[0032] The technical solution is described below in conjunction with specific implementation methods. Figures 1-9 As shown, Figure 1 and Figure 2 This is a three-dimensional schematic diagram of the first embodiment of the heat exchange assembly provided by the present invention from two directions. Figure 3 is a schematic diagram of the main viewing direction of the heat exchange component, Figure 4 for Figure 3 A schematic diagram of the AA section of the component shown, Figure 5 This is the exploded diagram of the component. Figure 5a is a partial schematic diagram of the first heat exchange part of the heat exchange assembly, Figure 6 is a three-dimensional schematic diagram of the bridge of this component, Figure 7 for Figure 6 The main view of the bridge and the schematic diagram of the BB direction section are shown. Figure 8 、 Figure 9The figure is a three-dimensional schematic diagram of the connecting parts of the component from two directions. As shown in the figure, the heat exchange component includes a first heat exchange part 10, a throttling element 110, a bridge 20, and a second heat exchange part 30. The bridge 20 is located between the first heat exchange part 10 and the second heat exchange part 30, or in other words, most of the bridge 20 is located between the first heat exchange part 10 and the second heat exchange part 30. In addition, there may be a connecting part 40, which is located on the other side of the second heat exchange part 30, or in other words, part of the second heat exchange part 30 is located between the bridge 20 and the connecting part 40, that is, the bridge 20 and the connecting part 40 are respectively arranged on both sides of the second heat exchange part. The first heat exchange part 10, the bridge 20, and the second heat exchange part 30 are fixed by welding, or the first heat exchange part 10, the bridge 20, the second heat exchange part 30, and the connecting parts are fixed by welding.

[0033] The first heat exchange part 10 has a heat exchange core. The first heat exchange part 10 may include at least two flow channels for fluid to flow through for heat exchange. The two fluid flow channels are separated. The first heat exchange part 10 includes interlayer flow channels separated by stacked plates. The first heat exchange part 10 can flow through at least two fluids. The two fluids can exchange heat in the first heat exchange part. For example, one fluid is a refrigerant and the other can be a coolant, such as used to cool heating elements such as batteries. In addition, it can also be used for three fluids, such as one fluid is a refrigerant and the other two can be coolants. The two coolants can be controlled to exchange heat with the refrigerant, and then the coolant can be used to cool the components that need to be cooled after heat exchange and cooling. The first heat exchange part 10 can also have only two channels, which are only connected to the refrigerant channel and are in contact with other components or media that need heat exchange for heat exchange. The following is an example of two fluids.

[0034] The heat exchange assembly includes a first interface 53, a second interface 54, a third interface 55, a fourth interface 56, and a fifth interface 57. In this embodiment, the bridge 20 is provided with the first interface 53, and the connector 40 is provided with the second interface 54, the third interface 55, the fourth interface 56, and the fifth interface 57. The throttling element 110 is fixed or positionally fixed to the first heat exchange portion 10. The first heat exchange portion 10 has four channels (not all of which are shown in the figure), including a first channel 103 and a second channel 104. The first heat exchange portion is also provided with a tube having a communication port 105 in channel 104, which is connected to the throttling element 110. The first heat exchange portion 10 includes a first coolant interface portion 101 and a second coolant interface portion 102. The first coolant interface portion 101 has a first coolant interface 51, and the second coolant interface portion 102 has a second coolant interface 52. The first coolant interface 51 and the second coolant interface 52 are connected through the coolant flow channel of the heat exchange core. The first heat exchange portion 10 has two channels connected to the first coolant interface 51 and the second coolant interface 52. The first channel of the first heat exchange portion is connected to the second channel through the refrigerant flow channel, and the coolant flow channel is not connected to the refrigerant flow channel. The first coolant interface portion 101 and the second coolant interface portion 102 can be part of the side plate of the first heat exchange portion, or they can be separately processed and fixed to the side plate and / or the heat exchange core of the first heat exchange portion by welding. The first coolant interface portion and the second coolant interface portion can also be fixed to the first heat exchange portion in the form of pipe fittings.

[0035] The bridge 20 has a first matching portion 200 and a second matching portion 200'. Correspondingly, the first heat exchange portion 10 has a matching portion 100, which matches the first matching portion 200 of the bridge. The second heat exchange portion 30 has a matching portion 300, which matches the second matching portion 200' of the bridge. The matching portion 100 of the first heat exchange portion 10, the matching portion 300 of the second heat exchange portion 30 and the two matching portions of the bridge all include a planar portion. The hole, groove or opening of the conducting portion for communication provided on the side of the first matching portion 200 of the bridge is located inside the first matching portion. Each opening for communication The first heat exchange part 10 is surrounded by the first matching part on all sides, and the first heat exchange part has a corresponding communicating mouth at a position corresponding to the position of each communicating mouth of the bridge, and the mouth of the first heat exchange part for communicating with the bridge is located inside its matching part and is surrounded by the matching part; in this way, after the matching part 100 of the first heat exchange part 10 and the first matching part 200 of the bridge are welded and sealed, the communicating mouth of the bridge can be communicated with the corresponding communicating mouth of the first heat exchange part, or in other words, each communicating mouth is surrounded by a part of the matching part, and both form a roughly closed structure at the relatively arranged matching parts. The matching portion 300 of the second heat exchange part 30 corresponds to the position of the second matching portion 200' of the bridge. After the two are welded and sealed, the mouth of the bridge on this side for communication is connected to the mouth of a channel of the second heat exchange part for communication. Specifically, the second heat exchange part 30 has two channel mouths on the side opposite to the bridge 20: the mouth of the third channel 301 and the mouth of the first channel 303. The bridge 20 has the mouth of the guide hole 202 and the mouth of the hole 2041 of the conductive part 204 on the side opposite to the second heat exchange part 30, that is, the second matching portion. The mouth of the third channel 301 of the second heat exchange part corresponds to and is connected with the position of the mouth of the guide hole 202, and the mouth of the first channel 303 corresponds to and is connected with the position of the mouth of the hole 2041 of the conductive part 204. The mouth of the hole 2041 is roughly extended up and down.

[0036] The terms "up" and "down" in this document are for clarity and should not be construed as limiting. They correspond to the height direction. Holes herein include, but are not limited to, through holes and blind holes. Holes can be circular or non-circular. Slots generally refer to non-through holes, but also include most non-through holes but partially through holes.

[0037] The bridge 20 includes a first interface portion 211, which has a first interface 53. The first interface portion 211 includes an outwardly protruding structure. The first interface portion 211 can be an integral structure of the bridge body, or a separately machined structure secured to the bridge body by welding. The flow guide hole 202 is similar to a through hole and communicates with the first interface 53. The flow guide hole 202 is connected to the connecting port 105 and the third channel 301 of the second heat exchange portion. The conducting portion 204 includes a hole 2041 and a groove 2042. The hole 2041 is similar to a through hole, and the groove 2042 is similar to a blind hole. The mouth of the groove 2042 is located on the side where the first mating portion is located. The groove 2042 is a blind hole, and other blind holes or grooves for communication can be provided on the bridge opposite the groove 2042. In this article, the side of the bridge facing the first heat exchange part is defined as the front side, and the side of the bridge facing the second heat exchange part is defined as the back side. In this example, the groove 2042 can also be a through hole, that is, the entire conductive part 204 can be configured as a through hole-like structure.

[0038] The connector 40 includes a main body 4010 and an extension 4011. The connector 40 is provided with a second interface 54, a third interface 55, a fourth interface 56, and a fifth interface 57. In addition, a fixing hole 409 is provided for cooperating with fixation or limiting. The connector 40 has a groove 405 on the side facing the second heat exchange portion 30. The groove 405 is a structure similar to a blind hole. The fifth interface 57 is provided in the groove 405 relatively close to the second interface 54. The third interface 55 is provided approximately in the middle of the groove 405. The third interface 55 is connected to the groove 405, and the fifth interface 57 is connected to the groove 405. The third interface 55 and the fifth interface 57 are roughly located between the second interface 54 and the fourth interface 56, making the connection relatively convenient. The connector may also include a fixing member 450 for fixing or limiting. The fixing member 450 can be fixed or limited in the fixing hole 409. In this embodiment, an extension portion 4011 is provided, and the main body 4010 and the extension portion 4011 have a groove 405, and the groove 405 is connected to the third interface 55 and the fifth interface 57. In this way, the second interface 54, the third interface 55, the fourth interface 56, and the fifth interface 57 can be provided on the main body 4010, so that the connection of each interface is relatively convenient and compact.

[0039] The heat exchange component can make the thermal management system easy to install and connect, reduce the number of connected pipes, and reduce the size of the system. Figure 5The heat exchange assembly is used in a vehicle thermal management system as an example for illustration. It should be noted that these components are fixed in actual use. For clarity of explanation, the flow of the refrigerant is shown in the exploded view. This is only for clarity of explanation. The vehicle thermal management system includes a battery thermal management system, which can include a first heat exchange part of the heat exchange assembly. The vehicle thermal management system includes a refrigerant flow channel and a coolant flow channel; the vehicle thermal management system includes a compressor, a condenser, at least one evaporator, and a heat exchange assembly. The coolant flow channel flows through the first coolant interface 101, the second coolant interface 102, and the flow channel portion of the first heat exchange portion that is connected to the first coolant interface 51 and the second coolant interface 52; the heat energy of the battery is transferred to the coolant, which flows through the first coolant interface 51 or the second coolant interface 52 through the flow channel of the first heat exchange portion, exchanges heat with the refrigerant in the other flow channel in the first heat exchange portion, and the coolant is returned after being cooled to cool the battery.

[0040] The refrigerant flow channel flows through the condenser, compressor, evaporator, and even the liquid storage tank, such as the first interface 53, the second interface 54, the third interface 55, the fourth interface 56, and the fifth interface 57, which are respectively used to connect with the refrigerant system. The inlet of the compressor can be connected to the second interface 54, such as the refrigerant cooled by the condenser enters the heat exchange component through the first interface 53, or the refrigerant through the liquid storage tank enters the heat exchange component through the first interface 53, so that the high-temperature and high-pressure refrigerant can be divided into two parts through the guide hole 202, one part goes to the third channel 301 of the second heat exchange part, and after heat exchange with the refrigerant in another channel in the second heat exchange part 30, it goes to the fourth channel 302, and the refrigerant in the fourth channel 302 flows out through the flow channel formed by the space where the groove 405 is located, formed by the cooperation of the connector 40 and the second heat exchange part, and flows out through the third interface 55 and the fifth interface 57, such as going to the front evaporator through the third interface 55 and to the rear evaporator through the fifth interface 57, or going to the rear evaporator through the third interface 55 and to the front evaporator through the fifth interface 57, in the front evaporator A throttling element can also be provided before the evaporator or the rear evaporator; another part of the refrigerant enters the throttling element 110 through the communication port 105 connected to the throttling element, enters the channel of the first heat exchange part 10 after being throttled by the throttling element 110, and exchanges heat between the refrigerant flow channel of the first heat exchange part and the coolant in the coolant flow channel, reaches the first channel 103, and passes through the flow channel formed by the conducting part 204 coordinated by the bridge, the first heat exchange part, and the second heat exchange part, reaches the first channel 303 of the second heat exchange part, and exchanges heat with the coolant in the coolant flow channel of the second heat exchange part. The refrigerant flowing from the second channel to the first channel converges and flows out through the second interface 54 connected to the first channel 303, such as returning to the compressor; in addition, the fourth interface 56 can be used to connect the refrigerant flowing back from the front evaporator and / or the rear evaporator. This part of the low-temperature refrigerant flows to the first channel 303 through the second channel 304 of the second heat exchange part, and performs heat exchange with the high-temperature refrigerant flowing from the third channel 301 to the fourth channel 302. In the first channel 303, the two parts of the refrigerant converge and can flow back to the compressor through the second interface. In this way, part of the low-temperature refrigerant is used to cool the high-temperature refrigerant, which can reduce the condensation temperature of the refrigerant without making the temperature of the refrigerant returning to the compressor higher. That is, the first flow channel and the second flow channel in this example are both parts of the guide hole, and the third flow channel is mainly the space where the conductive part 204 in the component is located.

[0041] The flow directions described herein are for illustrative purposes only and are not intended to be limiting or a requirement for closure. Other components, such as control valves before the compressor, may be added. Bridge 20 also features a first mounting portion 207 for mounting a sensor element 250, such as a temperature sensor. A temperature sensing head 2501 passes through the mounting portion and into the flow path where the conductive portion 204 is located. This allows the refrigerant temperature after passing through the first heat exchange section, or the evaporator outlet temperature, to be determined.

[0042] The heat exchange component can realize the heat exchange between part of the high-temperature refrigerant and part of the low-temperature refrigerant, reduce the temperature of the high-temperature refrigerant, and will not make the temperature of the refrigerant returning to the compressor too high, thereby improving efficiency. In addition, the setting of pipelines between interfaces can be reduced, and the system connection is simple and convenient. In addition, in order to further reduce the weight, the bridge can also be Figure 10 As shown, the bridge is an improvement of the above embodiment. The conducting portion 204' of the bridge is a through hole arranged approximately diagonally. The first mounting portion 207 is connected to the first end 204a of the conducting portion 204'. The temperature sensing head 2501 passes through the mounting portion and is located in the flow channel where the first end 204a of the conducting portion 204' is located; the first channel 103 of the first heat exchange portion is arranged opposite to and connected to the first end 204a of the conducting portion 204', the first channel 303 of the second heat exchange portion is arranged opposite to and connected to the second end 204b of the conducting portion 204', and the first channel 103 of the first heat exchange portion is connected to the first channel 303 of the second heat exchange portion through the third flow channel formed by the space where the conducting portion 204' is located; the bridge also removes two pieces of holes respectively formed for weight reduction. Hole 2032 can be of non-standard shape and can be removed as needed for welding. The hole is a through hole, and the bridge has a guide groove 202', which is connected to the guide hole 202. The distance between hole 2032 and the guide hole 202 of the bridge facing the first heat exchange unit for communication is greater than or equal to 1.5 mm, and the distance between hole 2032 and the conductive portion 204' of the bridge is greater than or equal to 1.5 mm. The distance between hole 2032 and the guide groove 202' of the bridge facing the second heat exchange unit is greater than or equal to 1.5 mm, and the distance between hole 2032 and the guide groove 202' of the bridge facing the second heat exchange unit for communication, or the distance between hole 2032 and the matching portions of the bridge for welding with the first and second heat exchange units is greater than or equal to 1.5 mm. However, weight-saving holes do not necessarily have to be through holes. For example, if both sides of the bridge are concave inward and blind holes or grooves are formed on both sides, both can reduce weight and facilitate welding. However, through holes are more suitable for processing. In this way, the area of ​​the first matching part of the bridge for matching with the first heat exchange part can be reduced, and similarly, the area of ​​the second matching part for matching with the second heat exchange part can be reduced. In this way, the area of ​​matching welding can be reduced, which helps to improve the welding quality and reduce the weight.

[0043] In this solution, one refrigerant connection port is located on the bridge, while the remaining refrigerant connections are located on the connector. This makes connection easier and keeps the piping on the same side. A sixth port can also be included to connect to the refrigerant outlet of another evaporator. The ports can also be located directly on the second heat exchange section, such as by providing a refrigerant port on the side panel of the second heat exchange section.

[0044] The flow directions in this article are for illustration only and are not intended to be limiting or a requirement for closure. Other components may be added, such as other control valves in front of the compressor.

[0045] The heat exchange components can also be Figure 11-14 As shown, Figure 11 is a three-dimensional schematic diagram of a second embodiment of a heat exchange assembly, Figure 12 for Figure 11 Schematic diagram of the explosion of the heat exchange component shown, Figure 13 for Figure 11 The main view of the bridge of the heat exchange component and the schematic diagram of the FF direction cross-section are shown.

The bridge 20 is mostly located between the first heat exchange section 10 and the second heat exchange section 30, and the connector is located on the other side of the second heat exchange section 30. That is, the bridge 20 and the connector are arranged on both sides of the second heat exchange section, or in other words, the second heat exchange section 30 is at least partially located between the bridge 20 and the first heat exchange section 10. The first heat exchange section 10, the bridge 20, and the second heat exchange section 30 are fixed by welding, or the first heat exchange section 10, the bridge 20, the second heat exchange section 30, and the connector are fixed by welding. In this embodiment, the first heat exchange section 10 is larger than the second heat exchange section 30.

[0046] The first heat exchange part 10 has a heat exchange core. The first heat exchange part 10 includes at least two flow channels for fluid to flow through for heat exchange. The two fluid flow channels are separated. The first heat exchange part 10 includes interlayer flow channels separated by stacked plates. The first heat exchange part 10 can flow through at least two fluids. The two fluids can exchange heat in the first heat exchange part. For example, one fluid is a refrigerant and the other can be a coolant, such as used to cool heating elements such as batteries or to cool the vehicle compartment. In addition, it can also be used for three fluids, such as one fluid is a refrigerant and the other two can be coolants. The two coolants can be controlled to exchange heat with the refrigerant, and then the coolant can be used to cool the components that need to be cooled after heat exchange and cooling. The following is an example of two fluids.

[0047] The heat exchange assembly has a first coolant port 51, a second coolant port 52, a first port 53, a second port 54, a third port 55, and a fourth port 56.

[0054] The heat exchange component can make the vehicle thermal management system easy to install and connect, reduce the number of connected pipes, and reduce the volume of the system. Taking the heat exchange component used in a vehicle thermal management system as an example, it should be noted that these components are fixed in actual use. For the sake of clarity, the flow of the refrigerant is shown in the exploded view. This is just for the sake of clarity. The vehicle thermal management system has a refrigerant flow path and a coolant flow path. The vehicle thermal management system includes a refrigerant system and also has a battery thermal management system. The battery thermal management system includes a part of the refrigerant system.

The heat of the battery can be transferred to the coolant, which flows through the first coolant interface 51 or the second coolant interface 52 through the flow channel of the first heat exchange portion, and exchanges heat with the refrigerant in the other flow channel in the first heat exchange portion. After cooling, the coolant returns to cool the battery. The first interface 53, the second interface 54, the third interface 55, and the fourth interface 56 are used for connecting the refrigerant system. For example, the refrigerant cooled by the condenser enters the heat exchange component through the first interface 53 of the bridge, or the refrigerant through the liquid storage device enters the heat exchange component through the first interface 53. In this way, the high-temperature and high-pressure refrigerant is divided into two parts through the guide hole 202.

A portion 441 flows out from the third interface 55, and is directed to the front evaporator or other evaporators through the third interface 55. A throttling element can also be provided in front of the front evaporator; the other portion of the refrigerant passes through the guide hole 202, the groove 2080 and the inclined hole 2082 of the bridge, enters the throttling element 110, and after being throttled by the throttling element 110, passes through the hole 2091 to the second channel 104 of the first heat exchange part 10, and performs heat exchange between the refrigerant flow channel of the first heat exchange part and the coolant in the coolant flow channel, and reaches the first channel 103, and passes through The through hole 2084 of the bridge is connected to the first channel 303 of the second heat exchange part, and the refrigerant flowing from the second channel 304 to the first channel 303 is merged and flows out through the second interface 54 connected to the first channel 303, such as returning to the compressor; In addition, the fourth interface 56 can be used to connect the refrigerant flowing back from the front evaporator or other evaporators, such as the refrigerant flowing out of the third interface is throttled by the throttling element, evaporated in the evaporator, and flows from the fourth interface to the second channel 304. This part of the low-temperature refrigerant passes through the second channel 304 of the second heat exchange part. 04 flows to the first channel 303 and exchanges heat with the high-temperature refrigerant flowing from the third channel 301 to the fourth channel 302. In the first channel 303, the two parts of the refrigerant converge and can flow back to the compressor through the second interface. In this way, part of the low-temperature refrigerant is used to cool part of the high-temperature refrigerant, which can reduce the condensation temperature of this part of the refrigerant without making the temperature of the refrigerant returning to the compressor too high, so that the high-temperature refrigerant can be supercooled to meet the needs of the system, and the high-temperature refrigerant that does not need to be supercooled can no longer pass through the second heat exchange part. The flow direction in this article is for illustration only and cannot be used as a limitation, nor is it a requirement for closure.

[0061] The heat exchange component can make the thermal management system easy to install and connect, reduce the number of connected pipes, and reduce the size of the system. Taking the heat exchange component used in a vehicle thermal management system as an example, it should be noted that these components are relatively fixed in actual use. For the sake of clarity, the flow of the refrigerant is shown in the exploded view. This is just for the sake of clarity. The vehicle thermal management system has a refrigerant flow path and a coolant flow path. The vehicle thermal management system includes a refrigerant system. Part of the refrigerant system is used for the battery thermal management system. Figure 16In other views, the battery thermal management system includes a first heat exchange part of the heat exchange component, and the coolant flow path includes a first coolant interface part 101, a second coolant interface part 102, and a flow channel part in the first heat exchange part that is connected to the first coolant interface and the second coolant interface. The heat of the battery can be transferred to the coolant, which flows through the coolant flow channel of the first heat exchange part through the first coolant interface 51 or the second coolant interface 52, and exchanges heat with the refrigerant in the refrigerant flow channel in the first heat exchange part. After cooling, the coolant returns to cool the battery. The first interface 53, the second interface 54, the third interface 55, and the fourth interface 56 are respectively used to connect with the refrigerant system. For example, the refrigerant cooled by the condenser enters the heat exchange component through the first interface 53, or the refrigerant through the liquid storage enters the heat exchange component through the first interface 53. In this way, the high-temperature and high-pressure refrigerant is divided into two parts through the first interface 53 of the bridge. One part passes through the guide hole 202, the second flow channel formed by the space where the guide groove 264 is located in cooperation between the bridge and the second heat exchange part, and reaches the third channel 301 of the second heat exchange part. After the heat exchange portion 30 exchanges heat with the refrigerant in another flow channel, it flows to the fourth channel 302 and flows out from the third interface 55 through the connector 45. For example, the third interface 55 leads to the front evaporator or other evaporators. A throttling element may be provided before the evaporator, or the refrigerant may be split to two evaporators after throttling, or may be split and throttled before entering the evaporator. Another part of the refrigerant passes through the guide hole 202 of the bridge and enters the throttling element 110 through the connecting port 105 connected to the throttling element. After throttling by the throttling element 110, it enters the second channel 104 of the first heat exchange portion 10. , and the refrigerant flow channel of the first heat exchange part exchanges heat with the coolant in the coolant flow channel, reaches the first channel 103, and passes through the third channel to the first channel 303 of the second heat exchange part. The third channel includes the groove 265, the hole 266, or at least a portion of the space of both, and merges with the refrigerant flowing from the second channel to the first channel and flows out through the second interface corresponding to the first channel 303, such as returning to the compressor; In addition, the fourth interface 56 can be used to connect the refrigerant from the previous evaporator and other evaporators that needs to flow back to the compressor. This part of low-temperature refrigerant flows through the connection piece 45 and the second heat exchange part in the flow channel formed by the space where the groove 455 is located to the second channel 304 of the second heat exchange part, and flows to the first channel 303, and exchanges heat with the high-temperature refrigerant flowing from the third channel 301 to the fourth channel 302. In the first channel 303, the two parts of refrigerant converge and can flow back to the compressor through the second interface 54. In this way, part of the low-temperature refrigerant is used to cool part of the high-temperature refrigerant, which can reduce the temperature of this part of the refrigerant without making the temperature of the refrigerant returned to the compressor too high. The bridge 20 is also provided with a first mounting portion 207 for mounting a sensor element 250, such as a temperature sensor element, so that the temperature sensing head 2501 passes through the mounting portion and is located in the third flow channel where the hole 266 or the groove 265 is located. In this way, the temperature of the refrigerant after passing through the first heat exchange part or the outlet temperature of the evaporator can be obtained.The second heat exchange part can realize heat exchange between high-temperature refrigerant and part of low-temperature refrigerant, reduce the temperature of high-temperature refrigerant, and will not make the temperature of refrigerant returning to the compressor too high, thereby improving efficiency.

[0062] The heat exchange component includes a first heat exchange part, a bridge, and a second heat exchange part. The bridge is at least partially located between the first heat exchange part and the second heat exchange part. The bridge is used for diversion, so that a part of the refrigerant flows to the first heat exchange part after throttling, and the other part flows to the second heat exchange part for supercooling. The fluid communication between the two heat exchange parts can be achieved relatively conveniently. Different system requirements can be achieved by changing the structure of the bridge, which makes the system pipeline simple, reduces the setting of pipelines between interfaces, and makes the system connection simple and convenient. The refrigerant flow channel of the first heat exchange part of the above-mentioned component can be a single flow, that is, flowing from the second channel 104 to the first channel 103, and can also be a three-flow flow, that is, the first heat exchange part is roughly divided into three parts horizontally. The first flow flows from the lowermost part of the second channel 104 to the lowermost part of the first channel 103, then flows from the middle part of the first channel 103 to the middle part of the second channel 104, and then flows from the upper part of the second channel 104 to the upper part of the first channel 103. Therefore, the embodiment only describes the outflow from the first channel 103. Unless otherwise specified, the thickness of the bridge refers to the thickness between the planar portions of the two mating parts of the bridge.

[0063] The flow directions described herein are for illustrative purposes only and are not intended to be limiting or a requirement for closure. Other components, such as control valves before the compressor, may be added. For example, the flow to the evaporator may include a throttling element or even a control valve before the evaporator. The second channel 104 of the first heat exchange unit is connected to the outlet of the throttling element 110. The channels of the first and second heat exchange units facing the bridge may not have an opening. These technical solutions can be modified based on the actual system, and the connectivity will be determined by the specific technical solution. For example, if the first coolant interface is connected to the second coolant interface, this does not preclude simultaneous connectivity with other interfaces.

[0064] In addition, the first heat exchange part can only have a refrigerant flow channel, and the throttling element is set on the bridge. The element or medium to be cooled is in contact with the outward side of the first heat exchange part, such as surface contact, for heat exchange, which can also achieve the purpose of heat exchange.

[0065] It should be noted that the above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. For example, with respect to the directional definitions of “front”, “back”, “left”, “right”, “up” and “down”, although this specification has described the present invention in detail with reference to the above embodiments, it should be understood by those skilled in the art that the present invention can still be modified, combined or replaced by equivalents, and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention should be included within the scope of the claims of this solution.
