However, in the conventional integrated layout, the compressor, heating device, controller, and other components are integrated in sequence along the same direction, which will cause the entire integrated device to be too long, and in actual applications, it is usually difficult for a vehicle to have enough length to accommodate the component. In addition, during the long-term operation of the integrated device, the controller generates a lot of heat under high load and has poor heat dissipation, which will affect the stability and reliability of the controller and the entire integrated device in the long run. Summary of the invention

[0036] This embodiment provides a thermal management integrated device. Figures 1 to 3As shown, the thermal management integrated device includes a compressor 1, a heating component 2 and a controller 3. The compressor 1 has a working chamber 102 for the flow of refrigerant, and a connecting portion 11 is provided on the radial side of the compressor 1, and a cooling groove 111 is provided on the connecting portion 11. The controller 3 is fixedly arranged on the connecting portion 11, and together with the cooling groove 111, a cooling chamber 101 is enclosed. The cooling groove 111 is provided with an inflow hole 1111 and an outflow hole 1112 connected to the working chamber 102. The refrigerant in the working chamber 102 can enter through the inflow hole 1111 and flow through the cooling chamber 101 and then return to the working chamber 102 through the outflow hole 1112. The compressor 1 and the heating component 2 are both communicatively connected to the controller 3.

[0037] Exemplarily, the heating component 2 is externally connected to a heat exchange medium box to form a heat exchange circuit; the compressor 1, together with the condenser, evaporator, and expansion valve, forms a refrigerant circuit. In a complete refrigeration cycle, the compressor 1 compresses the low-temperature and low-pressure refrigerant into a high-temperature and high-pressure refrigerant, which enters the condenser to exchange heat with the external environment. After cooling, the refrigerant enters the expansion valve to reduce the pressure, and then the low-temperature and low-pressure refrigerant enters the evaporator to exchange heat with the internal environment of the vehicle, and then returns to the compressor 1 to complete a cycle. The heat exchange medium in the heat exchange medium box enters the heating component 2 for heating and is then discharged from the heating component 2 to the vehicle's heating system. After heat exchange in the heating system, it flows back into the heating component 2 to form a complete heating cycle.

[0038] In this embodiment, a connecting portion 11 is provided on the radial side of the compressor 1 itself, and the controller 3 is fixed on the connecting portion 11, that is, the controller 3 is arranged on the radial circumferential side of the compressor 1. Such an arrangement can effectively reduce the layout length of the thermal management integrated device along the axial direction of the compressor 1, reasonably layout the space, and facilitate the arrangement inside the vehicle in practical applications. In addition, by providing a cooling groove 111 on the connecting portion 11, an inflow hole 1111 and an outflow hole 1112 connected to the internal working chamber 102 of the compressor 1 are provided in the cooling groove 111, and the controller 3 is fixed to the connecting portion 11 and enclosed together with the cooling groove 111 to form a cooling chamber 101. When the compressor 1 is working, the refrigerant in the working chamber 102 flows in a directional manner, and a part of the refrigerant enters the cooling chamber 101 through the inflow hole 1111, and returns to the working chamber 102 through the outflow hole 1112 after flowing through the cooling chamber 101. This part of the refrigerant can effectively cool the controller 3, thereby reliably cooling and dissipating the controller 3, avoiding overheating of the controller 3, and ensuring that the integrated device as a whole performs reliable performance.

[0039] In this embodiment, the compressor 1 and the heating component 2 are both in communication connection with the controller 3, and the controller 3 is used to simultaneously realize the functions of cooling of the compressor 1 and heating of the heating component 2.

[0040] In this embodiment, the controller 3 may be configured as an IPM control unit or an IGBT control unit.

[0041] In this embodiment, the thermal management integrated device further includes a circulation pump 4 , which can be integrated at one side of the heating component 2 and connected to the heating component 2 .

[0042] Specifically, the compressor 1 has an air intake port 14 and an air exhaust port 15, which are spaced apart along the axial direction of the compressor 1. The air intake port 14 and the air exhaust port 15 are both connected to the working chamber 102.

[0043] In this embodiment, the heating component 2 is fixedly arranged at the end of the compressor 1 in the axial direction, and the heating component 2 has a first supporting end surface 21 arranged flush with the supporting end of the connecting portion 11, and the controller 3 is jointly supported on the connecting portion 11 and the first supporting end surface 21. Specifically, the heating component 2 is arranged at the end side of the compressor 1 itself in the axial direction. Such an arrangement can further reduce the layout length of the thermal management integrated device along the axial direction of the compressor 1 and reasonably arrange the space. In addition, the arrangement of the first supporting end surface 21 is equivalent to the compressor 1 and the heating component 2 jointly supporting the housing of the controller 3, which effectively improves the connection strength of the integrated device as a whole and ensures that the integrated device as a whole is more solid and reliable.

[0044] Further, the circulation pump 4 is connected to the liquid inlet end of the heating component 2, and the circulation pump 4 is in communication connection with the controller 3. The circulation pump 4 is arranged on the heating component 2, and has a second support end surface 41 arranged flush with the support end of the connection part 11, and the controller 3 is supported on the connection part 11, the first support end surface 21 and the second support end surface 41. In this arrangement, the controller 3 is supported by the first support end surface 21, the second support end surface 41 and the support end of the connection part 11, further ensuring that the overall strength of the integrated device is reliable and stable.

[0045] Specifically, the heating assembly 2 includes a shell and a heating element. The shell has a heat exchange cavity. The heating element is arranged in the heat exchange cavity. The shell is provided with a liquid inlet 22 and a liquid outlet 23 connected to the heat exchange cavity. The first support end surface 21 is arranged on the shell. The circulation pump 4 is fixedly arranged on one side of the shell. The circulation pump 4 has a pump inlet 42 and a pump outlet. The pump outlet is connected to the liquid inlet 22. The circulation pump 4 is also connected to the controller 3 for communication. Specifically, the circulation pump 4 pumps out the heat exchange medium from the heat exchange medium box through the pump outlet and the liquid inlet 22 into the heat exchange cavity. After being heated by the heating element, it is discharged from the liquid outlet 23 to the heating system of the vehicle. After heat exchange in the heating system, it returns to the pump inlet 42 of the circulation pump 4, and flows back into the circulation cavity after being driven by the circulation pump 4, forming a complete heating cycle.

[0046] In this embodiment, the controller 3 is provided with a first plug connector, and the supporting end of the connecting portion 11 is correspondingly provided with a first plug hole 112, and the first plug connector is fixedly plugged into the first plug hole 112. The cooperation between the first plug connector and the first plug hole 112 can realize a reliable connection between the compressor 1 and the controller 3. Furthermore, the first plug connector can also have an electrical communication function. The controller 3 is connected to the compressor 1 through the first plug connector. The controller 3 realizes an electrical communication function with the compressor 1 through the first plug connector, thereby controlling the operation of the compressor 1.

[0047] In this embodiment, the controller 3 is provided with a second plug connector, and a second plug hole 211 is correspondingly provided on the first support end surface 21, and the second plug connector is fixedly plugged into the second plug hole 211. The cooperation between the second plug connector and the second plug hole 211 can realize a reliable connection between the heating component 2 and the controller 3. Furthermore, the second plug connector can also have an electrical communication function. The controller 3 realizes an electrical communication function with the internal heating element of the heating component 2 through the second plug connector, thereby controlling the heating work of the heating element.

[0048] In this embodiment, the controller 3 is provided with a third plug connector, and a third plug hole 411 is correspondingly provided on the second support end surface 41, and the third plug connector is fixedly plugged into the third plug hole 411. The cooperation between the third plug connector and the third plug hole 411 can realize a reliable connection between the circulation pump 4 and the controller 3. Furthermore, the third plug connector can also have an electrical communication function. The controller 3 realizes an electrical communication function with the circulation pump 4 through the third plug connector, thereby controlling the circulation pump 4 to work.

[0049] In this embodiment, a support platform 12 for supporting the controller 3 is provided on the connection portion 11. Specifically, the support end of the support platform 12 is set as a plane, which can be adapted to the housing of the controller 3, so as to facilitate reliable fixing of the controller 3.

[0050] In this embodiment, the connection part 11 is integrally formed with the radial side of the compressor 1. Since the shell of the compressor 1 and the connection part 11 have a relatively simple structure, the integral forming is convenient and efficient, and the process of separate assembly of the compressor 1 and the connection part 11 is omitted, which is highly practical.

[0051] Furthermore, a sealing ring 13 is provided between the cooling groove 111 and the controller 3, and the sealing ring 13 is used to seal the gap between the cooling groove 111 and the controller 3. By providing the sealing ring 13, the gap between the cooling groove 111 and the controller 3 can be effectively sealed to prevent the refrigerant in the cooling cavity 101 from leaking.

[0052] Optionally, the material of the sealing ring 13 is set to rubber, which is easy to process and low in cost.

[0053] Furthermore, the controller 3 has an electrical connector 31, and the electrical connector 31 is used to be plugged into an external power source. The external power source is electrically connected to the controller 3 through the electrical connector 31, so as to supply power to the controller 3.

[0054] Reference Figure 4 As shown, in some other optional embodiments, the heating assembly 2 is fixedly arranged on the side of the controller 3 facing away from the compressor 1. Such an arrangement is equivalent to the compressor 1, the controller 3 and the heating assembly 2 being arranged in sequence along the radial direction of the compressor 1. Compared with the compressor 1, the controller 3 and the heating assembly 2 being arranged in sequence along the axial direction of the compressor 1, the overall length of the integrated device can be reduced to a certain extent, the space can be reasonably arranged, and it is convenient for the arrangement inside the vehicle in practical applications.
