[0037] Some embodiments of the arrangement for transporting media according to the present disclosure are explained in more detail below with reference to the figures. These show, each schematically:

[0038] FIG. 1 a first embodiment of an arrangement in section;

[0039] FIG. 2 a second embodiment of an arrangement in section;

[0040] FIG. 3 the arrangement according to FIG. 1 in cross-section.

DETAILED DESCRIPTION

[0041] The figures show an arrangement 1 for transporting media. In the present embodiments, the arrangement 1 serves to transport temperature control media in the form of a cooling liquid. The arrangement 1 is part of the temperature control unit of an electric vehicle. Accordingly, temperature control medium in form of cooling liquid flows through the flow channels 4, 5, 7 formed in the arrangement 1 to the batteries, the power electronics, the charging electronics and the electric motors.

[0042] The arrangement 1 comprises a base body 2 in form of a hollow body which forms a wall 3 delimiting flow channels 4, 5. A separating body 6 is embedded in the base body 2 to separate the two flow channels 4, 5 from each other.

[0043] The base body 2 is designed as a blow-molded part and is made of polymeric material.

[0044] To produce the arrangement 1, a separating body 6 is placed in a blow mold, then a preform which at least partially accommodates the separating body 6 is placed in the blow mold. In the present embodiment, the preform is formed as a tube which is slipped over the separating body 6. Depending on the design of the arrangement 1, functional elements 9, for example valves, pumps, sensors and the like, can then be arranged in the blow mold. The blow mold is then closed and the base body 2 is formed from the preform in the blow molding process. Due to the fact that the preform is slipped over the separating body 6, the separating body 6 is embedded in the base body 2 after blow molding. As a result of the blow molding, flow channels 4, 5, 7 are formed inside the base body 2, wherein the flow channels 4, 5, 7 are delimited from one another by the wall 3 of the base body 2 and the separating body 6.

[0045] According to an alternative method, a preform is first placed in the blow mold which comprises two mold halves provided with a cavity, wherein the preform preferably is formed as a tube, the blow mold is then closed by moving the two mold halves towards each other, and the base body 2 is first formed by means of blow molding. In a next step, the blow mold is opened, wherein the base body 2 is fixed in the blow mold in such a way that the base body 2 tears into two base body parts along the seam created between the two mold halves. The separating body 6 or several separating bodies 6 and, if necessary, one or more functional elements 9 are inserted between the two base body parts and the blow mold is closed again, wherein the two base body parts join again becoming materially bonded to form the base body 2. Preferably, the joining of the two base body parts takes place shortly after the shaping of the base body 2, so that the temperature of the base body parts is sufficient for a material bond.

[0046] FIG. 1 shows a first embodiment of the arrangement 1 in which the separating body 6 is plane. In the present embodiment, the separating body 6 is made of metallic material. In the present embodiment, the separating body 6 forms a heat transmitter. To improve heat transfer, the surfaces facing the flow channels 4, 5 are textured. According to an advantageous embodiment, the separating body 6 is formed from injection-moldable plastic.

[0047] The arrangement according to FIG. 1 has eight flow channels 4, 4, 4, 4, 5, 5, 5, 5, wherein the flow channels 4, 4, 4, 4 as well as the flow channels 5, 5, 5, 5 are each arranged one above the other and the flow channels 4, 4, 4, 4 are each adjacent to the flow channels 5, 5, 5, 5. Next to each other adjacent flow channels 4, 4, 4, 4, 5, 5, 5, 5 are separated from each other by the separating body 6, respectively, and the flow channels 4, 4, 4, 4, 5, 5, 5, 5 arranged one above the other are each delimited by the wall 3 formed from the base body 2.

[0048] In the embodiment according to FIG. 2, the separating body 6 is also a blow-molded part and forms a hollow body. The separating body 6 is made of polymeric material by blow molding. Further flow channels 7, 7, 7 are formed in the separating body 6.

[0049] The separating body 6 forms a further wall 8 separating the further flow channels 7, 7, 7 from the flow channels 4, 4, 4, 4, 5, 5, 5, 5. The base body 2 surrounds the separating body 6 in a shell-shaped manner. Accordingly, the arrangement has 13 flow channels, wherein flow channels are embedded one above the other and next to each other in the base body 2.

[0050] FIG. 3 shows an arrangement 1 according to FIG. 1 in cross-section, wherein the sectional plane extends through the base body 2. In this embodiment, a functional element 9 influencing the flow channels 4, 4, 4, 4, 4, 5, 5, 5, 5, 5 is arranged in the base body 2. The flow channels designated 5, 5, 5, 5, 5 are located in mirror image to the flow channels 4, 4, 4, 4, 4, wherein all flow channels end in the functional element 9. In the present embodiment, the functional element 9 is a valve, wherein the functional element 9 has openings 10 that are in contact with the flow channels 4, 4, 4, 4, 4, 5, 5, 5, 5, 5. Specifically, the valve is a rotary valve.

[0051] In this case, the flow channels 4, 4, 4, 4 4, 5, 5, 5, 5, 5 end in openings 10 of the rotary valve, wherein two openings 10 are arranged in a plane perpendicular to the longitudinal axis in each case. As a result, the flow channels 4, 4, 4, 4,4 and 5, 5, 5, 5, 5 respectively end one above the other, and the flow channels 4, 5 and 4, 5 and 4, 5 and 4, 5 and 4, 5 respectively open next to each other in a plane perpendicular to the longitudinal axis of the valve core pivoted in the rotary valve.

[0052] Embedded in the base body 2, is a further functional element (not shown) in the form of a check valve which influences a flow channel.
