DETAILED DESCRIPTION OF THE INVENTION

(18) FIG. 1 shows a heat pump 100 comprising an evaporator for evaporating working liquid within an evaporator space 102. The heat pump further includes a condenser for condensing evaporated working liquid within a condenser space 104 bounded by a condenser base 106. As shown in FIG. 1, which can be regarded both as a sectional representation and as a side view, the evaporator space 102 is at least partially surrounded by the condenser space 104. Moreover, the evaporator space 102 is separated from the condenser space 104 by the condenser base 106. In addition, the condenser base is connected to an evaporator base 108 so as to define the evaporator space 102. In one implementation, a compressor 110 is provided above the evaporator space 102 or at a different location, said compressor 110 not being explained in detail in FIG. 1 but being configured, in principle, to compress evaporated working liquid and to direct same into the condenser space 104 as compressed vapor 112. Moreover, the condenser space is bounded toward the outside by a condenser wall 114. The condenser wall 114 is also attached to the evaporator base 108, as is the condenser base 106. In particular, the dimensioning of the condenser base 106 in the area forming the interface with the evaporator base 108 is such that in the embodiment shown in FIG. 1, the condenser base is fully surrounded by the condenser space wall 114. This means that the condenser space extends right up to the evaporator base, as shown in FIG. 1, and that the evaporator base simultaneously extends very far upward, typically almost through the entire condenser space 104.

(19) This interleaved or intermeshing arrangement of the condenser and the evaporator, which arrangement is characterized in that the condenser base is connected to the evaporator base, provides a particularly high level of heat pump efficiency and therefore enables a particularly compact design of a heat pump. In terms of order of magnitude, dimensioning of the heat pump, e.g., in a cylindrical shape, is such that the condenser wall 114 represents a cylinder having a diameter of between 30 and 90 cm and a height of between 40 and 100 cm. However, the dimensioning can be selected as a function of the power class of the heat pump that may be used, but will range within the dimensions mentioned. Thus, a very compact design is achieved which additionally is easy to produce at low cost since the number of interfaces, in particular for the evaporator space subjected to almost a vacuum, can be readily reduced when the evaporator base in accordance with embodiments of the present invention is configured such that it includes all of the liquid feed inlets/discharge outlets and such that, as a result, no liquid feed inlets/discharge outlets from the side or from the top may be used.

(20) In addition, it shall be noted that the operating direction of the heat pump is as shown in FIG. 1. This means that during operation, the evaporator base defines the lower portion of the heat pump, however, apart from lines connecting it to other heat pumps or to corresponding pump units. This means that during operation, the vapor produced within the evaporator space rises upward and is redirected by the motor and is fed into the condenser space from top to bottom, and that the condenser liquid is directed from bottom to top and is then supplied to the condenser space from the top and then flows from top to bottom within the condenser space such as by means of individual droplets or by means of small liquid streams so as to react with the compressed vapor, which is supplied in a transverse direction, for the purposes of condensation.

(21) FIG. 2A and FIG. 2B show a condenser base 106 in accordance with an embodiment of the present invention. In addition, FIGS. 3A to 3E show an evaporator base 108 in accordance with an embodiment of the present invention, FIG. 4A showing a complete heat pump in a sectional representation, said heat pump including both the evaporator base 108 and the condenser base 106.

(22) As shown in FIGS. 3A to 4A or also in FIG. 1, the condenser base 106 has a cross-section tapering from an intake for the working liquid to be evaporated to an exhaust opening 115 coupled to the compressor, or motor, 110, i.e., where the used radial impeller of the motor exhausts the vapor generated within the evaporator space 102.

(23) As shown in FIGS. 3A to 3E, the evaporator base includes an evaporator intake 301 for the working liquid to be evaporated and an evaporator drain 312 for a working liquid cooled by the evaporation. In the embodiments shown in FIGS. 3A to 3E, the evaporator base further includes a condenser intake 322 for condenser liquid and a condenser drain 332 for a condenser liquid heated because of the condensation. The condenser intake 322 or the condenser drain 332 are arranged on the evaporator base 108 such that a connection from the condenser intake 322 and/or condenser drain 332 to the respective locations within the condenser space extends outside the evaporation space 102. In embodiments this means, as shown in FIG. 3A, that the condenser intake 322 and the condenser drain 332 are arranged externally on the evaporator base, specifically outside an interface shown at 340 in FIG. 3A, where the condenser base of FIG. 2A or FIG. 2B is placed for creating a pressure-tight connection. To this end, the condenser intake 322 is located within a recess 323, and the condenser drain 332 is also located within a recess 333 of the interface 340, the recesses 323, 333 relating to the circular shape of the evaporator-base bed plate.

(24) Said evaporator-base bed plate includes bores 342 on which the typically cylindrical condenser wall can be mounted, as will be described below with reference to FIG. 4A.

(25) The evaporator base further includes a first connection interface 346 for attaching a condenser wall as well as a second connection interface 342 for attaching a condenser base.

(26) In embodiments, in the evaporator base, the first connection interface 346 for attaching the condenser wall is configured such that is surrounds the second connection interface 342 for attaching the condenser base. Moreover, the first connection interface 346 for attaching the condenser wall is configured to be flat in further embodiments, and the second connection interface 342 for attaching the condenser base is configured to protrude in relation to the first connection interface. This can be seen in FIG. 3A, for example, the bores 342 being configured in the flat first connection interface.

(27) The condenser intake and the condenser drain are arranged on the edge of the evaporator base, while for optimum evaporation, the evaporator intake and/or the evaporator drain are arranged within a central region of the evaporator base. In particular, the evaporator intake 301 is located centrally, i.e., in the center of the circular evaporator base, as can be seen particularly in FIG. 3E. In addition, the evaporator drain is located relatively close to the evaporator intake at 312 in FIG. 3E, for example. The evaporator drain 312 is arranged as far away as possible from the evaporator intake. However, it is advantageous for a certain distance to be taken, specifically in order to facilitate reliable and durable sealing, on the one hand, and to achieve a good flow behavior of the cooled evaporator liquid on the evaporator base, on the other hand.

(28) Moreover, the region around the evaporator drain 312 is configured such that the level is lower than in the opposite region, so that the working liquid present on the evaporator base drains off toward the evaporator drain 312 from any position of the evaporator base and enters the drain pipe, if possible, without any cavitations and/or inevitable formation of eddies. This means that, for example within a region 343, the slope of the evaporator base toward the evaporator drain is less pronounced than within a region 344 since within the region 344 there is the problem that the drain 312 should be arranged as close as possible to the edge of the evaporator base in order to achieve good flow accumulation.

(29) In addition, the evaporator base further includes a first sensor connection 351 and a second sensor connection 352. The first sensor connection 351 serves to detect a filling level within the evaporator space. The second sensor connection 352 serves to detect a temperature within the condenser space. Similar to the connections 322, 332, it thus also comprises a recess 353 in the connection interface for the condenser base defining the evaporator space which during operation is almost under a vacuum. The connection interface 346, in contrast, is configured to be without any recesses and to be circular so that the condenser wall can be screwed on there, as the case may be, while using gaskets. However, the pressure within the condenser is not as low as that within the evaporator space, so that the requirements placed upon the connection via the interface 346 are substantially lower than those for the interface 340.

(30) The condenser intake 322 is configured to consist of several parts. It includes a first component 322a and a second component 322b as well as, depending on the implementation, a smaller third component 322c. The first connection 322a and the second connection 322b as well as the third connection 322c extend into a shared connection 322d on the other side of the evaporator base. The first side, i.e., the lower side of the evaporator base, thus comprises the circular connection 322d, which along the connection pipe 322e splits up into the three portions 322a, 322b, 322c, at a corresponding connection pipe 322e extending away from the evaporator base. Moreover, the condenser may have a condenser liquid distribution arrangement, as is schematically shown at 402 in FIG. 4A, which comprises two or more feeding points. A first feeding point is therefore connected to the first portion 322a of the condenser intake. A second feeding point is connected to a second portion 322b of the condenser intake. Should there be more feeding points for the condenser liquid distribution means, the condenser intake will be split up into further portions. The third condenser intake portion 322 is connectable to a hose leading to a motor cooling means so that condenser liquid can flow around the motor 110 so as to achieve liquid cooling, as it were, which in particular is water cooling when the liquid used is water, which is advantageous.

(31) As shown in FIG. 3B, the condenser intake includes the shared connection pipe 322e, which has a circular shape, whereas the individual portions 322a, 322b, i.e., the split-up condenser intake portions, have elliptical cross-sections, the principal axes of the two elliptical cross-sections being arranged in a mutually oblique manner, as shown in FIG. 3A, for example.

(32) In one embodiment, the condenser drain includes, on the upper side of the evaporator base, shown in FIG. 3A, an upholstery nozzle shape, as it were, while it again has a circular shape on the second side, or lower side, of the evaporator base 108, said circular shape being bounded by a nozzle 332a in the downward direction. The shape of the condenser drain 332 on the upper side is such that a first boundary is that segment of the circle which at the same time is the boundary of the circular evaporator base, as shown at 332b. In contrast, the second portion 332c has a rather crescent-type shape that has a more pronounced curvature than the first portion 322b, to the effect that the evaporator space will be impaired to as small an extent as possible by the recess 333.

(33) In general, the condenser drain has a rather eye-type shape on the upper side and has a round shape on the lower side at the end of the nozzle 332a. In particular, the connection pipe is configured, along its extension, such that a cross-sectional area along the connection pipe from the upper side to the lower side and to the end of the nozzle is identical within a tolerance of 10% and that an inner wall of the connection pipe extends without any steps and discontinuities.

(34) In the implementation shown in FIGS. 3A to 3E, the evaporator base includes a reinforcement rib 360 arranged between the evaporator intake 301 and the evaporator drain 312. The reinforcement rib 360 is arranged, in particular, on an outer surface of the evaporator intake, which outer surface extends for a certain stretch within the evaporator base, and on an inner surface of the evaporator drain pipe. The reinforcement rib 360 provides structural stability, on the one hand, and interrupts a flow around the evaporator intake, on the other hand. In particular, the reinforcement rib 360 is configured such that it intercepts, as it were, the liquid impinging upon the reinforcement rib and redirects same into the evaporator drain so that a good and efficient drain flow is achieved.

(35) FIG. 2A and FIG. 2B show a side view and a perspective view, respectively, of a condenser base as can be placed onto the evaporator base of FIGS. 3A to 3E. In particular, the condenser base includes, on its lower side, an essentially circular interface 150, which has recesses 151 arranged therein, however, specifically for the condenser intake and the condenser drain as well as for the second sensor connection 352 of FIG. 3A. In FIG. 2B, the perspective view shows merely the recess 151 for the condenser intake, whereas the recess, not shown in FIG. 2B, for the condenser drain is located opposite.

(36) The condenser base has an almost chimney-type shape and extends from bottom to top, the cross-section continually decreasing from the bottom toward the top, so that the condenser base blends into a pipe having a relatively small cross-section as compared to the overall cross-section of the evaporator base, which pipe is shown at 115 in FIGS. 2A and 2B and represents the suction mouth for the evaporated working liquid. In particular, the condenser base has a shape that is round, apart from the recesses 151, in an attachment region 150 for attachment to the evaporator base. Moreover, the condenser wall 114 has a round shape in the attachment region on the evaporator base as well, the diameter of which shape, however, being larger than that of the condenser base, so that the condenser space extends right up to the evaporator base and the condenser base is arranged within the condenser wall.

(37) FIG. 4A shows a cross-section through the entire heat pump. What is shown, in particular, is that a droplet separator 404 is arranged within the condenser base. Said droplet separator includes individual blades 405. So that the droplet separator remains in its position, said blades are inserted into corresponding grooves 406 which are shown in FIG. 4A and are also shown in FIG. 2A. Said grooves are arranged, within the condenser base, in a region pointing toward the evaporator base, in the inside of the evaporator base. In addition, as shown in FIG. 2B, the condenser base further has various guiding features which can be configured as small rods 407 or tongues 408 for holding hoses provided, e.g., for a condenser water guidance, i.e., which are placed onto the portions 322a, 322b and possibly 322c and which couple the feeding points of the condenser water feed inlet. Said condenser water feed inlet 402 may be configured, depending on the implementation, such as is shown at reference numerals 102, 207 to 250 in FIGS. 6 and 7.

(38) FIG. 6 shows an embodiment of a condenser, the condenser in FIG. 6 comprising a vapor introduction zone 102 extending completely around the condensation zone 100. In particular, FIG. 6 shows a part of a condenser which comprises a condenser base 200. The condenser base has a condenser housing portion 202 arranged thereon which is drawn to be transparent in the representation of FIG. 6 but in reality need not necessarily be transparent but may be formed from plastic, die-cast aluminum or the like. The lateral housing part 202 rests upon a rubber seal 201 so as to achieve good sealing with the base 200. Moreover, the condenser includes a liquid drain 203 and a liquid intake 204 as well as a vapor feed inlet 205 centrally arranged within the condenser and tapering from bottom to top in FIG. 6. It shall be noted that FIG. 6 represents the actually desired installation direction of a heat pump and of a condenser of said heat pump; in this installation direction in FIG. 6, the evaporator of a heat pump is arranged below the condenser. The condensation zone 100 is bounded toward the outside by a basket-like boundary object 207, which just like the outer housing part 202 is drawn to be transparent and is normally configured in a basket-like manner.

(39) Moreover, a grid 209 is arranged which is configured to support fillers not shown in FIG. 6. As can be seen from FIG. 6, the basket 207 extends downward to a certain point only. The basket 207 is provided to be permeable to vapor so as to obtain fillers such as so called Pall rings, for example. Said fillers are introduced into the condensation zone, but only within the basket 207 and not within the vapor introduction zone 102. The fillers, however, are filled in to such a level, even outside the basket 207, that the height of the fillers extends either to the lower boundary of the basket 207 or slightly beyond.

(40) The condenser of FIG. 6 includes a working liquid feeder which is formedin particular by the working liquid feed inlet 204 which, as shown in FIG. 6, is arranged to be wound around the vapor feed inlet in the form of an ascending turnby a liquid transport region 210 and by a liquid distributor element 212 which may be configured as a perforated plate. In particular, the working liquid feeder is thus configured to feed the working liquid into the condensation zone.

(41) In addition, a vapor feeder is also provided which, as shown in FIG. 6, may be composed of the feeding region 205, which tapers in a funnel-shaped manner, and the upper vapor guiding region 213. Within the vapor guiding region 213, a wheel of a radial compressor may be employed, and the radial compression results in that vapor is sucked from the bottom upward through the feed inlet 205 and is then redirected, on account of the radial compression, by the radial wheel by 90 degrees to the outside, as it were, i.e. from flowing bottom-up to flowing from the center to the outside in FIG. 6 with regard to the element 213.

(42) What is not shown in FIG. 6 is a further redirecting unit, which redirects the vapor that has already been redirected toward the outside by another 90 degrees so as to then direct it from above into the gap 215 which represents the beginning of the vapor introduction zone, as it were, which extends laterally around the condensation zone. The vapor feeder is therefore configured to be ring-shaped and provided with a ring-shaped gap for feeding the vapor to the condensed, the working liquid feed inlet being configured within the ring-shaped gap.

(43) Please refer to FIG. 7 for illustration purposes. FIG. 7 shows a view of the lid region of the condenser of FIG. 6 from below. In particular, the perforated plate 212 which acts as a liquid distributor element is schematically depicted from below. The vapor entrance gap 215 is drawn schematically, and FIG. 7 shows that the vapor introduction gap is configured to be merely ring-shaped, such that vapor to be condensed is fed into the condensation zone neither directly from above nor directly from below, but is fed in from the sides all around only. Thus, only liquid, but no vapor, will flow through the holes of the distributor plate 212. The vapor is sucked into the condensation zone only from the sides, namely because of the liquid that has passed through the perforated plate 212. The liquid distributor plate may be formed from metal, plastic or a similar material and can be implemented with different hole patterns. As shown in FIG. 6, what is also to be provided is a lateral boundary for liquid flowing out of the element 210, said lateral boundary being designated by 217. In this manner it is ensured that liquid which exits the element 210 already with an angular momentum due to the curved feed inlet 204 and is distributed on the liquid distributor from the inside toward the outside will not splash over the edge into the vapor introduction zone, provided that the liquid has not previously dropped through the holes of the liquid distributor plate and has condensed with vapor.

(44) The upper region of the heat pump of FIG. 4A may thus be configured just like the upper region in FIG. 6, to the effect that feeding of the condenser water takes place via the perforated plate of FIG. 6 and FIG. 7, so that condenser water 408 trickling down is obtained into which the working vapor 112 is introduced in a lateral manner, so that cross-flow condensation, which allows a particularly high level of efficiency, can be obtained. As also depicted in FIG. 6, the condensation zone may be provided with a filling wherein the edge 207, which is also designated by 409, remains free from fillers or the like, to the effect that the working vapor 112 can still laterally enter into the condensation zone not only at the top, but also at the bottom. The imaginary boundary line 410 is to illustrate this in FIG. 4A.

(45) In the embodiment shown in FIG. 4A, however, the entire area of the condenser is configured with a condenser base 200 of its own which is configured above an evaporator base not shown in FIG. 6.

(46) FIG. 4B shows an alternative heat pump having an evaporator space and a condenser space, which again are arranged in a mutually interleaved manner. Moreover, the heat pump includes the evaporator base 108 and the condenser base 106 which, however, may be configured to be different from the elements shown in FIGS. 2 to 4. Moreover, a condenser connecting line 500 is shown, which may correspond to the feeding line 204 of FIG. 6 when one considers that only the upper side of the condenser space is configured as shown in FIG. 6. In addition, the evaporated working liquid is again fed in laterally via a gap, as shown at 112, whereas the condenser liquid trickles down, within the entire condenser space, from top to bottom, in the shape of drops or droplets, as shown at 510.

(47) The condenser base of FIG. 4B is depicted in more detail in FIG. 5A and FIG. 5B and again includes a condenser intake 322, a condenser drain 332, an evaporator intake 301 and an evaporator drain 312. Moreover, the evaporator base is configured with reinforcement ribs as shown in FIG. 5B, so that it can be manufactured by means of plastics injection molding while exhibiting good structural stability.

(48) Even though the evaporator base is described, e.g. in accordance with the implementation of FIGS. 3A to 3E, in connection with the condenser base, it shall be noted that the condenser base and the evaporator base can be produced and employed separately since they are connected by screwed connections anyhow. Thus, the evaporator base may be connected to a condenser base deviating from FIGS. 2A and 2B. Likewise, the condenser base of FIGS. 2A and 2B may be connected to a different one than the evaporator base of FIGS. 3A to 3E.

(49) In addition, the heat pump as is schematically shown in FIG. 1 may be implemented with elements deviating from the embodiments described, provided that the interleaved condenser/evaporator combination is maintained wherein the condenser base is connected to the evaporator base, even though the specific design of the corresponding elements may vary. All of the descriptions contained within this application which relate to the evaporator base equally relate to the entire heat pump, and vice versa. This means that all of the descriptions of the heat pump which show the features of the evaporator base also relate to the evaporator base by itself, even though this was not explicitly stated every time. Finally it shall be noted that the heat pump and the evaporator base may be used in combination or separately from each other.
