[0036] This embodiment provides a thermal management integrated device. Refer to Figures 1 to 5As shown in the figure, the thermal management integrated device includes a compressor 1, a heating component 2, a circulation pump 3, and a controller 4. Among them, the heating component 2 includes a housing 21 and a heating element 22. The housing 21 has a heat exchange cavity, and the heating element 22 is arranged in the heat exchange cavity. The housing 21 is provided with a liquid inlet 2111 and a liquid outlet 2112 that communicate with the heat exchange cavity. The circulation pump 3 is fixedly arranged on one side of the housing 21. The circulation pump 3 has a pump inlet 31 and a pump outlet 32. The pump outlet 32 communicates with the liquid inlet 2111. Both the compressor 1 and the housing 21 are fixed on the controller 4. The compressor 1, the heating element 22, and the circulation pump 3 are all communicatively connected to the controller 4.

[0037] In this embodiment, the pump inlet 31 of the circulation pump 3 and the liquid outlet 2112 of the heating component 2 are externally connected to a heat exchange medium tank to form a heat exchange loop; the compressor 1 and the condenser, evaporator, expansion valve, etc. together form a refrigerant loop. In a complete refrigeration cycle, the compressor 1 compresses the low-temperature and low-pressure refrigerant into a high-temperature and high-pressure refrigerant, enters the condenser to exchange heat with the external environment, and after cooling, the refrigerant enters the expansion valve to reduce pressure. Subsequently, the low-temperature and low-pressure refrigerant enters the evaporator to exchange heat with the vehicle interior environment, and then returns to the compressor 1 to complete a cycle. The circulation pump 3 pumps out the heat exchange medium from the heat exchange medium tank, passes through the pump outlet 32 and the liquid inlet 2111 into the heat exchange cavity, is heated by the heating element 22 and then discharged from the liquid outlet 2112 to the vehicle's heating system. After heat exchange in the heating system, it returns to the pump inlet 31 of the circulation pump 3, and is driven by the circulation pump 3 to flow back into the circulation cavity again to form a complete heating cycle. In the above structure, the compressor 1, the heater, and the circulation pump 3 are integrated on a controller 4, and through this controller 4, the control of functions such as the refrigeration of the compressor 1, the heating of the heater, and the circulation of the heat exchange medium can be realized simultaneously, which can effectively improve the overall integration of the device, reduce the component settings that occupy space, effectively reduce the setting cost, and facilitate the overall maintenance of the device.

[0038] In this embodiment, the circulation pump 3 can be either a high-pressure pump or a low-pressure pump. Specifically, the controller 4 can selectively output high-voltage electricity to supply power to the high-pressure circulation pump 3, and can also selectively output low-voltage electricity to supply power to the low-pressure circulation pump 3. The control board of the circulation pump 3 can be directly placed inside the controller 4, or can be fixed outside the housing of the controller 4 or the housing of the compressor 1, and is still electrically connected to the controller 4. In this way, if the circulation pump 3 fails alone, its control board is convenient to disassemble, reducing the maintenance cost.

[0039] In this embodiment, the heat exchange medium is set as a fluid medium. Preferably, the heat exchange medium is set as water.

[0040] As an alternative embodiment, refer to Figures 1 to 3As shown, on the same side along the first direction, the housing 21 has a first end face 2101, the controller 4 has a second end face 41, the first end face 2101 and the second end face 41 are flush with each other, and the circulation pump 3 is fixed on the first end face 2101 and the second end face 41. Specifically, Figure 1 , Figure 3 in Figure 1 and Figure 3 , the direction indicated by a is the first direction. The first end face 2101 of the housing 21 and the second end face 41 of the controller 4 are flush with each other, so as to be able to install the circulation pump 3 more reliably. The circulation pump 3 is provided with a bottom plate 33, and the bottom plate 33 is fixedly attached to both the first end face 2101 and the second end face 41 at the same time.

[0041] Specifically, the pump outlet 32 of the circulation pump 3 penetrates through the bottom plate 33, and the liquid inlet hole is opened on the first end face 2101. When the bottom plate 33 on the circulation pump 3 is fixedly attached to the first end face 2101, the pump outlet 32 and the liquid inlet hole are in an aligned and communicating position.

[0042] Optionally, a seal may be provided between the pump outlet 32 and the liquid inlet hole for sealing the gap between the pump outlet 32 and the liquid inlet hole.

[0043] Specifically, the second end face 41 is provided with a plug hole 42, and the bottom plate 33 is correspondingly provided with a plug 331, and the plug 331 is fixedly inserted into the plug hole 42. The corresponding setting of the plug hole 42 and the plug 331 can realize a reliable and effective connection between the circulation pump 3 and the controller 4. Optionally, electrical connectors such as conductive contacts may also be arranged at the plug 331 for directly extending into the controller 4 to realize electrical connection with the controller 4.

[0044] In addition, the plug 331 can be replaced with a bus bar, and the bus bar is directly inserted into the plug hole 42 to directly realize the electrical connection between the circulation pump 3 and the controller 4.

[0045] It is worth mentioning that since using a bus bar will cause electromagnetic leakage, the housing of the circulation pump 3 can be set to be formed by casting a metal part. After the metal housing of the circulation pump 3 is attached to the housing of the controller 4, effective EMC shielding can be carried out.

[0046] As an alternative implementation manner, referring to Figure 4 as shown, on the same side along the first direction, the housing 21 has a first end face 2101, the controller 4 has a second end face 41, and the first end face 2101 and the second end face 41 are arranged in a staggered manner. It can be understood that along the first direction, the first end face 2101 and the second end face 41 are not flush with each other. In the figure, it is equivalent to that the length of the controller 4 along the first direction is less than the length of the housing 21. The housing 21 is provided with a third end face 2102 along the second direction, and both the controller 4 and the circulation pump 3 are fixed on the third end face 2102, and the circulation pump 3 is fixedly abutted against the second end face 41 and is flush with the first end face 2101.Figure 4 In the a direction, it indicates the first direction, and in the b direction, it indicates the second direction. The first direction is perpendicular to the second direction. Specifically, since the length of the controller 4 in the first direction is less than the length of the outer shell 21, a certain area can be vacated between the first end face 2101 and the second end face 41 on the third end face 2102. The circulation pump 3 is arranged in this area. One side of the circulation pump 3 is fixedly attached to the third end face 2102, and the other end is provided with a pump outlet 32 and is fixedly attached to the second end face 41. The second end face 41 is correspondingly provided with a liquid inlet 2111 and is communicated with the pump outlet 32. With such a setting, the space of the controller 4 can be further utilized, the overall volume of the device can be reduced, and the integration is higher.

[0047] As an alternative implementation, referring to Figure 5 As shown, the circulation pump 3 and the controller 4 are fixed on opposite sides of the outer shell 21. Specifically, along the second direction, the circulation pump 3 and the controller 4 are fixed on opposite sides of the outer shell 21, and along the second direction, the compressor 1 and the outer shell 21 are fixed on opposite sides of the controller 4, that is, the compressor 1, the controller 4, the heating component 2, and the circulation pump 3 are arranged in sequence along the second direction. With such a setting, the structure is simple and the arrangement is convenient.

[0048] Continuing to refer to Figures 1 to 3 As shown, the heat exchange chamber has two relatively arranged chamber walls. A plurality of flow guide plates 23 are arranged at intervals on each chamber wall. The plurality of flow guide plates 23 on the two chamber walls are alternately interspersed. The heat exchange chamber and the plurality of flow guide plates 23 together form an S-shaped bent heat exchange flow path. The liquid inlet 2111 is communicated with the first end of the heat exchange flow path, and the liquid outlet 2112 is communicated with the second end of the heat exchange flow path. Specifically, the heat exchange medium can enter the first end of the heat exchange flow path through the liquid inlet 2111, flow through the heat exchange flow path, and then flow out through the liquid outlet 2112, circulating in this way. The setting of the heat exchange flow path can effectively extend the flow path of the heat exchange medium, enable the heat exchange medium to fully exchange heat in the heat exchange chamber, and ensure the heating effect.

[0049] Specifically, the outer shell 21 includes a shell body 211 and a shell cover 212. The shell cover 212 is covered with the shell body 211 to form a heat exchange chamber. The flow guide plates 23 are arranged in the shell body 211. Specifically, the first end face 2101 of the outer shell 21 in the above content is arranged on the shell body 211. Setting the outer shell 21 into the openable and closable structure of the shell body 211 and the shell cover 212 is convenient for cleaning the heat exchange chamber regularly.

[0050] Furthermore, a support boss 2113 is provided in the shell body 211. The heating element 22 is supported on the support boss 2113, and the flow guide plates 23 are arranged inside the support boss 2113. By setting the support boss 2113, it is convenient to reliably support the heating element 22.

[0051] Optionally, the flow guide plate 23 is integrally formed with the housing body 211. With this arrangement, the connecting components for the separate assembly between the flow guide plate 23 and the housing body 211 can be omitted, and the production and assembly time can be saved.

[0052] Optionally, a sealing ring 24 is further provided between the housing body 211 and the housing cover 212. The setting of the sealing ring 24 can effectively seal the gap between the housing body 211 and the housing cover 212, prevent the leakage of the heat exchange medium, and ensure reliable sealing performance.

[0053] The material of the sealing ring 24 is set as rubber.

[0054] Optionally, the heating element 22 includes a printed circuit and insulating films provided on opposite sides of the printed circuit, and the printed circuit is communicatively connected to the controller 4. Optionally, the insulating film can be made of a mixture of CaO, Al2O3, SiO2 or equivalent materials. The printed circuit can be made of a mixture of Ag, Pd and glass ceramics or equivalent materials.

[0055] In this embodiment, the compressor 1 includes a suction hole 11 and an exhaust hole 12 that are spaced apart along the same side of the compressor 1 itself, and the exhaust hole 12 is arranged on the side away from the controller 4 compared with the suction hole 11.

[0056] Specifically, the exhaust hole 12 is farther away from the controller 4 compared with the suction hole 11, that is, the controller 4 is correspondingly arranged with the low-pressure refrigerant suction side of the compressor 1. With this arrangement, the controller 4 is close to the refrigerant inlet side of the compressor 1, and the controller 4 can also be effectively cooled by the low-temperature refrigerant, further improving the heat dissipation effect.

[0057] Optionally, the compressor 1 can be a rotary compressor 1, a swash plate compressor 1, a scroll compressor 1, a piston compressor 1, etc.

[0058] Optionally, the housing of the compressor 1 and the housing of the controller 4 can be connected through external connecting components such as bolts.

[0059] In this embodiment, the controller 4 can be set as an IPM control unit or an IGBT control unit.

[0060] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
