DETAILED DESCRIPTION

[0065] A cooling component 10 is shown in the drawings, as it is used, for example, as part of the cooling of battery or of accumulator systems, respectively, of electric vehicles, in order to cool the respective batteries or the individual cells, respectively. In the present case, such a battery 25 is shown in an exemplary manner.

[0066] Such a cooling component 10 is thereby generally part of a superordinate cooling device, which ensures that cooling medium is continuously guided through the cooling component 10, which thereby absorbs waste heat of the object to be cooled and then dissipates said waste heat. The components of the cooling device, which are necessary for this, for example a suitable pump, inlet and outlet lines for the cooling medium, etc., are known in the prior art and are thus not explained in detail.

[0067] In the present case, the cooling component 10 can, for example when used, be connected to identical further cooling components of the cooling device, which are not shown here and can then cool several objects to be cooled at the same time, for example several batteries or battery cells, respectively.

[0068] The cooling component 10 has a metal profile 11 forming a heat sink, in the present case made of aluminum, which, when used, rests against the object to be cooled or is arranged at least directly adjacent thereto. In the present case, the profile 11 is made in one piece and was produced by means of the aluminum extrusion process, is thus an extruded profile. By nature, the metal profile or the extruded profile, respectively, can also consist of other metal materials.

[0069] The profile 11 is formed in an elongated manner, in the present case essentially as flat cuboid.

[0070] Based on the main direction of extension of the cooling component 10 or of the profile 11, respectively, a connection part 12 made of plastic is arranged in the region of an end 17 a thereof, via which cooling medium, such as, for example, cooling water or the like, can be fed to the cooling component 10, which cooling medium is then guided within a first group 14 a of elongated medium channels 14 in the main direction of extension of the profile 11 or in the longitudinal direction to the other end 17 b of the profile 11, respectively, is then diverted in a connector 13, which is arranged in a region of this other end 17 b, and flows in the opposite direction through a second group 14 b of elongated medium channels 14 in the opposite direction through the heat sink of the cooling component 10, until it reaches the connection part 12 again and is guided or discharged, respectively, out of the cooling component 10 via the connection part 12.

[0071] On its way through the profile 11 or through the medium cannels 14, respectively, the cooling medium absorbs the waste heat of the object to be cooled, here of the battery 25, during operation of the cooling device or of the cooling component 10, respectively, by cooling the object to be cooled and removes said waste heat.

[0072] In the present case, the profile 11 has four outer walls 15, namely a first large-surface, upper wall 15 a, a second large-surface lower wall 15 b lying opposite the upper wall in parallel at a distance, as well as two narrow side walls 15 c or 15 d, respectively, which run parallel to one another and which in each case connect the upper wall 15 a and the lower wall 15 b to one another.

[0073] The elongated medium channels 14 are arranged in the interior of the profile 11, thus in the interior of the space enclosed by the profile outer walls 15. The medium channels 14 thereby extend parallel to the main direction of extension of the profile 11 or parallel to the narrow side walls 15 c or 15 d, respectively. Based on a cross section through the profile 11, the individual medium channels 14 are arranged next to one another in a row.

[0074] Each elongated medium channel 14 is furthermore delimited by a circumferential medium channel wall 16 formed by the profile 11 on preferably all of its longitudinal sides, based on the main direction of extension of the respective medium channel 14. The circumferential medium channel wall 16 thereby describes a hollow cuboid orin the cross sectiona rectangle, respectively, wherein a cuboid is defined as special case of a rectangle in the context of this application.

[0075] In the present case, each circumferential medium channel wall 16 thereby in each case comprises concretely two pairs of wall sections each lying opposite one another at a distance.

[0076] On the one hand, each medium channel 14 is thereby delimited on two opposite longitudinal sides, which are vertical or run perpendicular, respectively, to the upper and lower large-surface wall 15 a or 15 b, respectively, namely in the transverse direction or perpendicular to the main direction of extension of the profile 11, respectively, by two lateral wall sections 16 a or 16 b, respectively, which in each case run parallel to one another in the main direction of extension of the profile 11 and which are spaced apart from one another. In the case of the two outer medium channels 14, one of said medium channel walls 16 a and 16 b is thereby in each case formed by the respective profile outer wall 15 of the profile 11, in the present case the narrow side wall 15 c or the narrow side wall 15 d, respectively.

[0077] On the other hand, each elongated medium channel 14 is in each case delimited on its other two longitudinal sides by an upper wall section 16 a and a lower wall section 16 b. The respective upper wall section 16 a is thereby in each case formed by a subsection of the upper large-surface wall 15 a of the profile 11 and the respective lower wall section 16 b is formed by a subsection of the lower large-surface wall 15 b.

[0078] In the present case, each medium channel 14 is furthermore not open on its ends but is closed in a fluid-tight manner on the two opposite profile ends 17 a and 17 b. As part of the manufacture of the cooling component 10, the wall sections 16 a and 16 b of the respective circumferential medium channel wall 16 of the respective medium channel 14 of the profile 11, which in each case initially lie opposite one another there at a distance, were, for this purpose, moved towards one another by means of a corresponding pressing device and were connected to one another in a fluid-tight manner, namely compressed in the present case while creating a weld seam, which was subsequently welded or soldered.

[0079] With regard to the connection part 12, the latter has an inlet chamber 18 with upper inlet opening 19, via which cooling medium can be fed to the cooling component 10 and consequently to the medium channels 14 of the first group 14 a of medium channels 14, as well as an outlet chamber 20, which is separated from the inlet chamber 18, with outlet opening 21, via which cooling medium can be discharged from the medium channels 14 of the second group 14 b of medium channels, in particular from the connection part 12 or from the cooling component 10, respectively.

[0080] In the present case, each circumferential medium channel wall 16 of each medium channel 14, namely in the present case in each case the upper wall section 16 a thereof, in each case has, for this purpose, in the region of the connection part 12, namely in the present case in the region of the first end 17 a of the profile 11, a through opening 22, via which the respective medium channel 14 is fluidically connected to the inlet opening 19 or to the outlet opening 21, respectively, of the connection part 12. This can in particular be a clearance, which is introduced there, for example, by means of a drilling tool or of a laser.

[0081] As can be seen, the individual through openings 22 of the circumferential medium channel walls 16 in each case merge into one another in the transverse direction of the profile 11 in the present case, are thus not spaced apart from one another, so that they form a common, cohesive profile opening 23, which in particular extends transversely to the medium channels 14, in the large-surface upper outer wall 15 a of the profile 11. However, this does not have to be the case, the individual through openings can also be spaced apart from one another.

[0082] The connection part 12 is placed onto the upper wall 15 a of the profile 11 so that the inlet chamber 18 and the outlet chamber 20 in each case covers the assigned through openings 22 for the fluidic connection of the respective medium channels 14 or that the through openings 22 lead into the inlet chamber 18, respectively, or the outlet chamber 20, respectively.

[0083] Concretely, the through openings 22 of the first group 14 a of medium channels 14 are arranged within the inlet chamber 18 so that the cooling medium can flow directly from the inlet chamber 18 into and/or via the through openings 22 into the medium channels 14 of said first group 14 a and the through openings of the second group 14 b of medium channels of the outlet chamber 20 in such a way that the cooling medium can flow directly from the outlet chamber 20 into and/or via the through openings 22 into the medium channels 14 of this second group 14 b.

[0084] With regard to the connector 13, through openings 22, which in the present case form a continuous profile opening 23, are in each case also introduced in the region of said connector, namely in the region of the second profile end 17 b, into the circumferential medium channel walls 16 of the medium channels 14, namely into the respective upper wall sections 16 a. In the case of this example, all of said through openings 22 are covered by this diverting space 24 or the through openings 22 lead into said diverting space, respectively.

[0085] Cooling medium, which flows there from the through openings 22 of the first group 14 a of medium channels 14 into the diverting space 24, is diverted in the diverting space 24 to the through openings 22 of the medium channels 14 of the second group 14 b of medium channels 14, enters into them in the opposite direction and then flowsin the second group 14 b of medium channelsthrough the profile 11 back to the connection part 12.

[0086] As already suggested abovein contrast to the profile 11the connection part 12 as well as the connector 13 do not consist of metal or optionally of a metal alloy but of plastic. In the present case, said components are thereby in each case formed in one piece and are produced as plastic injection molded part, for example of thermoplastic.

[0087] For the connection of the connection part 12 and of the connector 13 to the profile 11, connection regions or connection surfaces thereof, respectively, are in each case connected to connection regions or connection surfaces, respectively, of the profile 11 in a fluid-tight manner.

[0088] In the present case, the connection surfaces of the metal profile 11 in each case have three-dimensional nanostructures and/or microstructures, which are introduced into the respective surface by means of physical and/or chemical nano-structuring or micro-structuring methods, such as, for example, chemical etching or laser beam structuring.

[0089] Each of the connection surfaces of the profile 11, which are structured in the described manner, thereby in each case lies opposite an assigned connection surface of the connection part 12 or of the connector 13, respectively, and is connected thereto, namely for example compressed under thermal joining, as will be described in more detail below.

[0090] The concrete production of the cooling component 10 and in particular the above-mentioned connection of the metal cooling component 10 to the connection part 12 consisting of plastic and to the connector 13 consisting of plastic thereby takes place in a special way.

[0091] The profile 11, the connection part 12 and the connector 13 are initially prefabricated separately, extruded or injection molded, respectively, in the present case.

[0092] The through openings 22 are then introduced into the profile 11 by means of suitable manufacturing methods, such as separating and/or shaping. This can take place, for example, by means of drilling with a suitable, for example mechanical, drilling tool, or by means of a laser. Punching and/or bending and/or pressing of the profile material, preferably by means of punching, bending and/or pressing device, are also possible.

[0093] As already described in more detail above, the initially cuboid ends 17 a and 17 b of the profile 11 are additionally compressed by closing the ends of the medium channels 14 of the profile 11, which were previously open on the front side, so that a weld seam is created in each case. This weld seam is then welded or soldered in order to guarantee the fluid-tightness.

[0094] The above-mentioned components 11, 12, 13 are generally connected to one another thereafterit goes without saying that the order of different steps can also be changed. This will be described below in an exemplary manner using the connection of the connection part 12 to the profile 11. The connection of the profile 11 to the connection part 12 takes place analogously.

[0095] For the connection of profile 11 and connection part 12, said two components are initially moved and aligned relative to one another. For example, in that the connection part 12 is held in a stationary manner and the profile 11 is moved by means of a suitable conveying member in the direction of the connection part 12. It goes without saying that the process can also run in reverse or that both components can be moved towards one another.

[0096] In the course of the above-mentioned relative movement, the profile 11 is then moved relative to the connection part 12 in such a way that the connection surfaces of the profile 11 are placed so as to fit accurately, so that each of the connection surfaces of the profile 11 in each case lies opposite an assigned connection surface of the connection part 12.

[0097] Thereafter, during this time and/or before that, the metal profile 11, but at least the connection surfaces 26 of the profile 11, are then heated up or warmed up to a temperature, which corresponds at least to the softening temperature of the plastic of the connection part 12, in particular by means of an induction heater known in the prior art, but other heating techniques are obviously also conceivable.

[0098] The heat of the profile 11 is then transferred to the connection part 12 or the connection surfaces thereof, respectively, which then leads to a melting of the connection surfaces.

[0099] The respective connection surfaces are then pressed against one another and are thus connected in a fluid-tight manner, for example by means of a or optionally a respective pressing member, such as, for example, a pressing jaw, which is not shown here, which in each case pushes from the outside onto the walls of the connection part 12, which are to be connected, which is to be understood as thermal direct joining.

[0100] FIG. 8 shows an alternative design of a cooling component 10 with an individual channel control. The cooling component 10 comprises a metal profile 11 forming a heat sink, which is preferably extruded like the above-described profile 11 of FIG. 2. A connection part 12 made of plastic is arranged in the region of a first end 17a. Said connection part comprises an inlet chamber 18, via which the cooling medium can be fed into the cooling component 10. The connection part 12 furthermore comprises an outlet chamber 20, via which the coolant can be discharged from the cooling component 10. The second end 17b of the profile 11 comprises a connection part 13, by means of which a diversion of the coolant in the form of an individual channel control takes place between the medium channels 14, which are outlined in FIG. 11.

[0101] FIG. 9 shows an exploded view of the example according to FIG. 8. The profile 11 of the heat sink 10 comprises a plurality of through openings 22, wherein two through openings 22 for each medium channel 14 are in each case arranged on both ends 17a and 17b of the profile 11. The through openings 22.1 and 22.2 of the medium channels 14 of the first group 14a as well as the through openings 22.25 and 22.26 of the medium channels 14 of the second group 14b are identified in an exemplary manner in FIG. 9. The through openings 22 of the upper medium channel wall 16a are spaced apart from one another and do not merge into one another. Due to the fact that the medium channels 14 in each case have exactly one opening on both ends 17a and 17b, an individual control of the medium channels 14 with cooling medium is possible by means of a correspondingly formed connection part 12 as well as connector 13. An adaptation of the cooling component 10 can thus advantageously be adapted to the expected heat energy dissipation of a battery 25, for example.

[0102] The through openings 22 on the first end 17a of the profile 11 are covered completely by the connection part 12. The connection part 12 has the inlet chamber 18 with upper inlet opening 19. The inlet chamber 18 extends over both groups 14a and 14b of the medium channels 14. The connection part 12 furthermore has the outlet chamber 20 with the outlet opening 21. The outlet chamber 20 likewise extends over the two groups 14a and 14b of medium channels 14. As can be seen from FIG. 11, the through openings 22 are arranged on the first end 17a in such a way that they are covered by inlet chamber 18, outlet chamber 20 and diverting spaces.

[0103] FIG. 9 furthermore shows that the through openings 22 on the second end 17 of the profile 11 are covered completely by a connector 13.

[0104] FIG. 10 shows a further exploded view of the cooling component 10 according to FIG. 8. The cooling component 10 can be seen in a perspective view from the bottom. The connection part 12 comprises an inlet chamber 18, a part 18.1 of which is visible here. The outlet chamber 18.2 is covered by the profile 11 and can be seen in FIG. 11. The connection part 12 furthermore comprises an outlet chamber 20, the part 20.1 of which is visible here. The outlet chamber 20.2 is covered by the profile 11 and can be seen in FIG. 11. The connection part 12 furthermore comprises diverting spaces, the diverting space 24.3 of which is visible here. Further diverting spaces of the connection part 12 can be seen in FIG. 11.

[0105] FIG. 10 furthermore shows that the connector 13 comprises diverting spaces 24.1, 24.2, 24.4, 24.5, 24.7, 24.9, 24.10, 24.11, 24.13 and 24.14. The individual medium channels 14 outlined in FIG. 11 lead into them in order to divert the cooling medium in further medium channels 14.

[0106] FIG. 11 shows the cooling component 10 in a top view, wherein the connection part 12 and the connector 13 are cut longitudinally in a plane parallel to the heat sink. The connection part 12 has the inlet chamber 18, which is divided into two parts 18.1 and 18.2 in the sectional view. The inlet chamber parts 18.1 and 18.2 are communicatively connected to one another. In the sectional view, the outlet chamber 20 is likewise divided into two parts 20.1 and 20.2. Outlet chamber parts 20.1 and 20.2 are communicatively connected to one another.

[0107] The inlet chamber 18.1 leads into different medium channels 14 through the through openings 22.1, 22.5, 22.13 and 22.25. For the sake of clarity, the medium channels 14 are not individually provided with reference numerals in FIG. 11 but are outlined by means of arrows, which suggest the flow direction of the cooling medium. The cooling medium, which is fed into a medium channel through the through opening 22.1, is fed through the through opening 22.1 in the diverting space 24.1 and is guided from there via the through openings 22.3 into the adjacent medium channel and is finally fed into the outlet chamber 20.1. Starting at the inlet chamber 18.1, the coolant is furthermore fed through the through opening 22.5 into a medium channel 14 and is further guided through the through opening 22.6 to the diverting space 24.2 of the connector 13 and from there through the through opening 22.7 into a further medium channel 14. A diverting space 24.3, in which the cooling medium is guided from the through opening 22.8 via the through opening 22.9 into a further medium channel 14, is arranged in the connection part 12. The diverting space 24.4 then guides the cooling medium from the through opening 22.10 to the through opening 22.11 into the adjacent medium channel 14, which lastly leads into the outlet chamber 20.1 via the through opening 22.12.

[0108] Cooling medium is furthermore guided from the inlet chamber 18.1 via the through opening 22.13 into a medium channel 14. From there, the cooling medium flows through the through opening 22.14 into the diverting space 24.5 and from there through the through opening 22.15 into the adjacent media channel 14. The through opening 22.16 guides the cooling medium into the diverting space 22.6 and from there via the through opening 22.17 into the adjacent medium channel 14. The cooling medium is furthermore guided through the through opening 22.18 into the diverting space 22.7 and from there via the through opening 22.19 into the adjacent medium channel 14. The cooling medium is guided through the through openings 22.20 and 22.21 by means of the diverting space 24.8 into a further medium channel 14, which leads with the through opening 22.22 into the diverting space 24.9. From there, the cooling medium is guided via the through opening 22.23 into a medium channel and finally leads into the outlet chamber 20.1 via the through opening 22.24.

[0109] From the inlet chamber 18.1, the cooling medium furthermore flows through the through opening 22.25 into a further medium channel 14, which leads with the through opening 22.26 into the diverting space 24.10. From there, the cooling medium is guided through the through opening 22.27 into the medium channel 14 back through the through opening 22.28 into the outlet chamber 20.1.

[0110] The cooling medium is furthermore guided from the inlet chamber 18.1 through the through opening 22.25 into a medium channel 14 and from there through the through opening 22.26 into the diverting space 24.10. From there, the cooling medium is guided through the through opening 22.27 into the adjacent medium channel 14 and then through the through opening 22.28 into the outlet chamber 20.1.

[0111] Depending on the expected heat dissipation or cooling demands, respectively, the shown individual channel control can, however, not only control each medium channel 14 individually, but also several medium channels 14 at the same time. Starting at the inlet chamber 18.2, three medium channels 14 are thus fed through the through openings 22.29, 22.30 and 22.31. The medium channels 14 lead with the through openings 22.32, 22.33 and 22.34 into the diverting space 24.11, via which the cooling medium is further guided through the through openings 22.35, 22.36 and 22.37 into three further medium channels 14. A further diverting space 24.12 in the connection part 12 receives the cooling medium through the through openings 22.28, 22.39 and 22.40 and guides it into three adjacent medium channels 14 via the through openings 22.41, 22.42 and 22.43. In the diverting space 24.13, the cooling medium is guided from the through openings 22.44, 22.45 and 22.46 through the through openings 22.47, 22.48 and 22.49 into further medium channels 14. Said medium channels 14 lead via the through openings 22.50, 22.51 and 22.52 into the outlet chamber 20.2. The cooling medium furthermore flows from the inlet chamber 18.2 through the through openings 22.53 and 22.54 into the diverting space 24.14 and from there through the through openings 22.55 and 22.56 into the outlet chamber 20.2.

[0112] FIG. 12 shows a further alternative design of a cooling component 10 with individual channel control. The profile 11 as well as the connection part 12 with the inlet chamber 18 and the outlet chamber 20 as well as the connector 13 can be seen.

[0113] FIG. 13 shows an exploded view of the cooling component 10 according to FIG. 12. The profile 11 comprises a plurality of through openings 22, wherein the through openings 22.1, 22.5, 22.13, 22.25, 22.29, 22.30, 22.31 and 22.53, which are assigned to the inlet chamber 18, which is not visible here, are designed individually and are connected only via the inlet chamber 18, which can be seen in FIG. 15. The through openings 22.4, 22.12, 22.24, 22.28, 22.50, 22.51, 22.52 and 22.56 are also designed individually and are only connected via the outlet chamber 20, which can likewise be seen in FIG. 15. The remaining through openings 22, not all of which are provided with reference numerals here for the sake of clarity, are in particular those through openings 22, which lead into a diverting space 24 in the above-described design. In this example, however, the connection part 12 and the connector 13 do not comprise any diverting spaces. On the contrary, common wall sections of the circumferential medium channel wall 16 of the two adjacent medium channels 14 are interrupted in at least one region, which can be seen in an exemplary manner at the through opening 22.10. Cooling medium can flow in this way from the one to the other medium channel 14. In this design, the connector 13 seals the medium channels 14 towards the top in the region of the through openings 22 on the second end 17b.

[0114] FIG. 14 shows an exploded view of the cooling component 10 from the bottom. The connection part 12 comprises two inlet chambers 18.1 and 18.2, which are communicatively connected to one another and to the inlet opening 19. The connection part 12 furthermore comprises two outlet chambers 20.1 and 20.2, which are communicatively connected to one another and to the outlet opening 21. The connection part 12 does not comprise any diverting spaces. On the contrary, said connection part is designed in a flat manner on the side facing the profile 11 in the region of the through openings 22, which can be seen in FIG. 13 and the common wall sections of the circumferential medium channel wall 16 of which are interrupted in at least one region. The connection part 12 can thus seal exactly said through openings 22 towards the top.

[0115] The connector 13, which does not comprise any chambers or diverting spaces, can furthermore be gathered from FIG. 14. On the contrary, all through openings 22, which can be seen in FIG. 13, are sealed on the end 17b towards the top by means of the connector 13. The diverting spaces are not required in this example because common wall sections of the circumferential medium channel wall 16 are interrupted in at least one region, whereby the cooling medium can flow between the medium channels 14, which have the common medium channel wall 16.

[0116] FIG. 15 shows the cooling component 10 according to FIG. 12 in a top view, wherein the connection part 12 and the connector 13 are longitudinally cut in a plane parallel to the heat sink. The connection part 12 has the inlet chamber 18, which is divided into two parts 18.1 and 18.2 in the sectional view. The inlet chamber parts 18.1 and 18.2 are communicatively connected to one another. The inlet chamber 18.1, 18.2 leads through the through openings 22.1, 22.5, 22.13, 22.25, 22.29, 22.30, 22.31 and 22.53 into different medium channels 14, which are not illustrated here.

[0117] In the sectional view, the outlet chamber 20 is likewise divided into two parts 20.1 and 20.2. Outlet chamber parts 20.1 and 20.2 are communicatively connected to one another. Individual media channels 14 lead via the through openings 22.4, 22.12, 22.24, 22.28, 22.50, 22.51, 22.52 and 22.56 into the outlet chamber 20.1, 20.2.

[0118] Neither connection part 12 nor connector 13 comprise a diverting space because the cooling medium can flow between the medium channels 14 by means of the wall interruptions.

[0119] The medium channels 14 can advantageously be controlled with cooling medium by means of the individual channel control in the way it is required by an expected distribution of the heat dissipation of a heat source.
