The heat exchanger is a key component for transferring heat in the air to the refrigerant. Since heat transfer is required in the automobile heat pump system, and the heat in the air cannot be directly transferred to the refrigerant, the heat exchanger is used to transfer the heat in the air to the refrigerant, thereby achieving heating inside the automobile.

[0046] In some embodiments, the heat exchanger includes one or a combination of an evaporator, a condenser, a heater core, an intermediate heat exchanger, and a PTC heater.

[0047] In some embodiments, the heat exchanger can be an evaporator, which refers to a heat exchanger that absorbs heat from the inside of the vehicle by receiving low-temperature and low-pressure refrigerant circulating inside the vehicle, causing the refrigerant to evaporate and absorb heat from the inside of the vehicle, resulting in an increase in the temperature of the refrigerant.

[0048] In some embodiments, the heat exchanger can be a condenser, which refers to a heat exchanger that releases the heat absorbed by the refrigerant when it evaporates, causing the refrigerant to condense into a high-temperature and high-pressure state, while allowing external air to absorb heat.

[0049] In some embodiments, the heat exchanger can be an intermediate heat exchanger, which refers to a heat exchanger that connects the evaporator and the condenser, serving to transfer heat and lower the temperature of the refrigerant in the vehicle heat pump.

[0050] In some embodiments, the heat exchanger can be a PTC heater, which refers to a heat exchanger that generates heat by passing an electric current through PTC material, thereby achieving heating of an object. When the temperature exceeds a certain Curie temperature, the resistance value of the PTC material increases sharply with the increase in temperature, serving as a heat source.

[0051] In some embodiments, the heat exchanger can be a heater core, which refers to a heat exchanger that provides warm air.

[0052] The vehicle heat pump system is a new type of environmentally friendly and energy-saving technology that utilizes the heat in the air to heat the air inside the vehicle, thereby reducing dependence on traditional fuel. The heat exchanger in the vehicle heat pump system is an important component that plays a role in heat transfer. The heat exchanger is a key component that transfers heat from the air to the refrigerant. Since heat transfer is required in the vehicle heat pump system, and the heat in the air cannot be directly transferred by the refrigerant, a heat exchanger is needed to transfer the heat from the air to the refrigerant, thereby achieving heating inside the vehicle.

[0053] The working process of the heat exchanger is to transfer heat in the air to the refrigerant, thereby realizing heating of the interior of the automobile. The heat exchanger in the automobile heat pump system generally adopts a tube type or a plate type structure. In the working process, air passes through the pipeline or the plate of the heat exchanger, thereby transferring heat in the air to the refrigerant in the pipeline, so that the temperature of the refrigerant is increased. Then, the refrigerant enters the evaporator, at this time, the temperature of the refrigerant is higher than the temperature of the interior of the automobile, and the refrigerant releases heat, thereby increasing the temperature of the interior of the automobile. As can be seen, the heat exchanger is an important component in the automobile heat pump system. In the prior art, the PTC in the heat exchanger is electric heating, and the medium in the condenser or the warm air core body is water or refrigerant, so it needs to be spaced apart and cannot be integrated into one, resulting in a larger occupied space and lower heat exchange efficiency.

[0054] Therefore, in order to reduce the occupied space of the heat exchanger, the embodiment of the present application provides a heat exchanger as shown in the accompanying drawings. Figure 1 The heat exchanger comprises a first header 100, a second header 200, a heat exchange assembly 300 and a heat dissipation fin 400.

[0055] The first header 100 and the second header 200 are arranged in a spaced apart manner along a first direction X, and the first direction X is perpendicular to a vertical direction Y. It can be understood that the first header 100 and the second header 200 play a role of concentrating the medium.

[0056] The heat exchange assembly 300 is located between the first header 100 and the second header 200, and the two ends of the heat exchange assembly 300 are connected to the first header 100 and the second header 200 along the first direction X, respectively. It can be understood that the first header 100 and the second header 200 concentrate the medium at the two ends of the heat exchange assembly 300, respectively, so that the medium can be concentrated when flowing into or flowing out of the two ends of the heat exchange assembly 300, thereby improving the integration degree.

[0057] The heat exchange assembly 300 is arranged in a plurality of vertical directions Y, and the plurality of heat exchange assemblies 300 are arranged in a spaced apart manner, as shown in the accompanying drawings. Figure 2 The heat exchange assembly 300 comprises a first heat exchange layer 310 and a second heat exchange layer 320 arranged in the vertical direction Y. It can be understood that the first heat exchange layer 310 and the second heat exchange layer 320 can be attached, thereby increasing the contact area of the first heat exchange layer 310 and the second heat exchange layer 320 and reducing the occupied space of the single heat exchange assembly 300.

[0058] The heat dissipation fins 400 are located between any two adjacent heat exchange assemblies 300 along the vertical direction Y, so that any two adjacent heat exchange assemblies 300 along the vertical direction Y share the heat dissipation fins 400, and the first heat exchange layer 310 and the second heat exchange layer 320 are arranged in each heat exchange assembly 300 along the vertical direction Y, so that the heat dissipation fins 400 are in heat exchange with the first heat exchange layer 310 and the second heat exchange layer 320 in different heat exchange assemblies 300 along the two sides of the vertical direction Y, thereby improving the heat exchange efficiency.

[0059] It can be understood that the first heat exchange layer 310 and the second heat exchange layer 320 can be in heat exchange with the outside environment respectively, and the first heat exchange layer 310 and the second heat exchange layer 320 can also be in heat exchange with the outside environment simultaneously, and the first heat exchange layer 310 and the second heat exchange layer 320 can be stacked in the vertical direction, so that the integration of the heat exchange assembly 300 is higher.

[0060] In some embodiments, the first header 100 and the second header 200 can use a high-efficiency threaded copper pipe as an inner pipe, an outer treated galvanized steel pipe, and a metal pipe including but not limited to an aluminum pipe.

[0061] In other embodiments, the first heat exchange layer 310 is provided with a first heat exchange flow channel 311 for flowing a first medium, and the first medium includes but is not limited to one or more of water, refrigerant, coolant, or other refrigerant. The second heat exchange layer 320 is provided with a second heat exchange flow channel 321 for flowing a second medium, and the second medium includes but is not limited to one or more of water, refrigerant, coolant, or other refrigerant.

[0062] In the above scheme, the first medium and the second medium flow in the first heat exchange flow channel 311 and the second heat exchange flow channel 321 respectively, and the first medium and the second medium are two different mediums, so that the heat exchanger can select different heat exchange mediums to achieve different heat exchange speeds and heat exchange efficiencies.

[0063] In other embodiments, the first header 100 has a first medium inlet cavity 111 and a first medium outlet cavity 112. The first medium inlet cavity 111 concentrates the first medium flowing into the first heat exchange flow channels 311; and the first medium outlet cavity 112 concentrates the first medium flowing out of the first heat exchange flow channels 311.

[0064] The second header 200 has a first medium transfer cavity 211, which concentrates the first medium flowing out of part of the first heat exchange flow channels 311 and flowing into another part of the first heat exchange flow channels 311, plays a role of transferring the first medium, and can concentrate the first medium.

[0065] In some other embodiments, the first header 100 has a second medium inlet cavity 113 and a second medium outlet cavity 114. The second medium inlet cavity 113 collects the second medium flowing into the second heat exchange channels 321, and the second medium outlet cavity 114 collects the second medium flowing out of the second heat exchange channels 321.

[0066] The second header 200 has a second medium transfer cavity 212, which collects the second medium flowing out of some of the second heat exchange channels 321 and flowing into another part of the second heat exchange channels 321, plays a role of transferring the second medium, and can concentrate the second medium.

[0067] In some other embodiments, since the first header 100 and the second header 200 have the cavities described above, the integration of the heat exchanger is improved, which is conducive to improving the energy efficiency of the heat exchanger.

[0068] In some other embodiments, two ends of a part of the first heat exchange channels 311 are respectively in communication with the first medium inlet cavity 111 and the first medium transfer cavity 211. During heat exchange, the first medium in the first medium inlet cavity 111 flows through the part of the first heat exchange channels 311 to the first medium transfer cavity 211. It can be understood that the first medium is heat exchanged in the part of the first heat exchange channels 311 before entering the first medium transfer cavity 211.

[0069] Two ends of another part of the first heat exchange channels 311 are respectively in communication with the first medium transfer cavity 211 and the first medium outlet cavity 112. During heat exchange, the first medium in the first medium transfer cavity 211 flows through the other part of the first heat exchange channels 311 to the first medium outlet cavity 112. It can be understood that the first medium is heat exchanged in the other part of the first heat exchange channels 311 before entering the first medium outlet cavity 112.

[0070] Therefore, the first medium in the above scheme sequentially passes through the first medium inlet cavity 111, the part of the first heat exchange channels 311, the first medium transfer cavity 211, the other part of the first heat exchange channels 311, and the first medium outlet cavity 112. The first medium is heat exchanged in the two parts of the first heat exchange channels 311 respectively, which ensures the heat exchange effect.

[0071] In some other embodiments, two ends of a part of the second heat exchange channels 321 are respectively in communication with the second medium inlet cavity 113 and the second medium transfer cavity 212. During heat exchange, the second medium in the second medium inlet cavity 113 flows through the part of the second heat exchange channels 321 to the second medium transfer cavity 212. It can be understood that the second medium is heat exchanged in the part of the second heat exchange channels 321 before entering the second medium transfer cavity 212.

[0072] The other part of the plurality of second heat exchange channels 321 is in communication with the second medium switching cavity 212 and the second medium discharge cavity 114, respectively; when heat exchanging, the second medium in the second medium switching cavity 212 flows to the second medium discharge cavity 114 through the other part of the second heat exchange channels 321, and it can be understood that the second medium is heat exchanged in the other part of the second heat exchange channels 321 before entering the second medium discharge cavity 114.

[0073] Therefore, in the above scheme, the second medium sequentially passes through the second medium inlet cavity 113, the first part of the second heat exchange channel 321, the second medium switching cavity 212, the other part of the second heat exchange channel 321, and the second medium discharge cavity 114, and the second medium is heat exchanged in the two parts of the second heat exchange channel 321, respectively, which guarantees the heat exchange effect.

[0074] In other embodiments, the first manifold 100 is provided with a first partition plate 110 and a second partition plate 120 intersecting with each other, and the first partition plate 110 and the second partition plate 120 together separate the space in the first manifold 100 to form a first medium inlet cavity 111, a first medium discharge cavity 112, a second medium inlet cavity 113, and a second medium discharge cavity 114.

[0075] Specifically, the first partition plate 110 is divided into a first sub-plate 1101 and a second sub-plate 1102 by the second partition plate 120, and the second partition plate 120 is divided into a third sub-plate 1201 and a fourth sub-plate 1202 by the first partition plate 110; the first partition plate 110 and the second partition plate 120 simultaneously divide the inner wall of the first manifold 100 into a first inner wall 1001, a second inner wall 1002, a third inner wall 1003, and a fourth inner wall 1004; the cavity surrounded by the first sub-plate 1101, the third sub-plate 1201, and the first inner wall 1001 is the first medium inlet cavity 111, the cavity surrounded by the first sub-plate 1101, the fourth sub-plate 1202, and the second inner wall 1002 is the first medium discharge cavity 112, the cavity surrounded by the second sub-plate 1102, the fourth sub-plate 1202, and the third inner wall 1003 is the second medium inlet cavity 113, and the cavity surrounded by the second sub-plate 1102, the third sub-plate 1201, and the fourth inner wall 1004 is the second medium discharge cavity 114.

[0076] Therefore, in the above scheme, the first medium and the second medium in the first manifold 100 are separated by the second partition plate 120, realizing the concentration of different media in the same manifold; the inflow and outflow of the first medium and the inflow and outflow of the second medium are separated by the first partition plate 110, realizing the concentration of media in different directions in the same manifold; the integration is improved, and the occupied space is reduced.

[0077] In some other embodiments, the second manifold 200 is provided with a third partition plate 210, which divides the space in the second manifold 200 into two parts, forming a first medium transfer cavity 211 and a second medium transfer cavity 212.

[0078] Specifically, the third partition plate 210 also divides the inner wall of the second manifold 200 into a fifth inner wall 2001 and a sixth inner wall 2002. One side of the third partition plate 210 and the fifth inner wall 2001 form a cavity, which is the first medium transfer cavity 211. The other side of the third partition plate 210 and the sixth inner wall 2002 form a cavity, which is the second medium transfer cavity 212.

[0079] Therefore, in the above scheme, the first medium and the second medium in the second manifold 200 are separated by the third partition plate 210, realizing the concentration of different media in the same manifold, improving the integration and reducing the occupied space.

[0080] In some other embodiments, at least part or all of the first partition plate 110, the second partition plate 120 and the third partition plate 210 are made of heat-conducting material, so that the cavities in the first manifold 100 can exchange heat, and the cavities in the second manifold 200 can exchange heat, improving the heat exchange effect.

[0081] In some other embodiments, along the vertical direction Y, the first medium inlet cavity 111 and the second medium outlet cavity 114 are located on the same side, the first medium outlet cavity 112 and the second medium inlet cavity 113 are located on the other side, the first heat exchange layer 310 is connected with the first medium inlet cavity 111 and the first medium outlet cavity 112, and the second heat exchange layer 320 is connected with the second medium inlet cavity 113 and the second medium outlet cavity 114.
