The thermal management system includes a compressor assembly, which includes a first housing 1, a compressor control module 2, a second housing 4, and a third housing 14. The two ends of the first housing 1 are respectively connected to the third housing 14 and the second housing 4.
[0030] Specifically, the thermal management system includes a thermal management control module 3 and several first heat sinks 5. A third housing 14 has an intake port 6 and an exhaust port 7. A first housing 1 is located near the intake port 6 and has a first cavity. The compressor control module 2 is located within the first cavity. A second housing 4 has a second cavity, and the first and second cavities are connected. The thermal management control module 3 is located within the second cavity. Several first heat sinks 5 are spaced apart on the outer surface of the second housing 4. The compressor control module 2 and the thermal management control module 3 are communicatively connected. This system places the first housing 1 near the intake port 6. Through heat conduction, the refrigerant can carry away heat from the first housing 1 and the second housing 4. Simultaneously, the first heat sinks 5 can dissipate heat from the second housing 4, thereby cooling the compressor control module 2 and the thermal management control module 3. This bidirectional heat dissipation improves heat dissipation efficiency and prevents damage to the power component 16. Furthermore, integrating the thermal management control module 3 into the compressor assembly simplifies wiring, reduces wiring harnesses, and saves space.

Specifically, the first housing 1 and the second housing 4 are connected by bolts 15, and the seal 8 is disposed between the first housing 1 and the second housing 4 to seal against water vapor or oil mist entering the first and second cavities. Further, the seal 8 is a gasket.
[0032] Optionally, the thermal management system further includes a partition 9. The first housing 1 has a first opening, and the second housing 4 has a second opening. The partition 9 is disposed between the first housing 1 and the second housing 4 to seal the first and second openings.

[0033] Furthermore, the inner wall of the second housing 4 is provided with a stepped portion 41, and the partition 9 abuts against the end face of the stepped portion 41. Specifically, the inner wall of the second housing 4 is provided with a stepped portion 41 protruding circumferentially, and the partition 9 covers the stepped portion 41, completely enclosing the thermal management control module 3 in the second cavity, so as to ensure that there is no electromagnetic compatibility effect between the compressor control module 2 and the thermal management control module 3.
[0034] Optionally, the thermal management system further includes a first plug-in 10, which is disposed in the first housing 1 and electrically connected to the compressor assembly.

[0035] Optionally, the thermal management system further includes a second connector 11, which is disposed in the first housing 1 and electrically connected to the compressor control module 2. Specifically, the second connector 11 is a high-pressure connector, which connects the compressor control module 2 to the PTC heating device, and the compressor control module 2 controls the PTC heating device.

Specifically, the plurality of protrusions 13 are connected to form a region, and the first heat sinks 5 and the power components 16 on the thermal management control module 3 are respectively in close contact with the inner and outer sides of the region, so as to dissipate heat from the power components 16 by means of air.
[0038] Optionally, the thermal management system also includes a pin header 17, which passes through the partition 9, and whose two ends are connected to the compressor control module 2 and the thermal management control module 3, respectively. Compared with the traditional structure, this structure omits the low-voltage connector connection between the compressor control module 2 and the thermal management control module 3. Using the pin header 17 for internal connection is cheaper and reduces wiring. Furthermore, the compressor control module 2 and the thermal management control module 3 can share some modules, such as the communication module and the power management module, further reducing costs.
[0039] Optionally, the thermal management system also includes a plurality of second heat dissipation components 18, which are spaced apart on the outer surface of the end where the first housing 1 and the third housing 14 are connected, enabling the compressor control module 2 to dissipate heat by relying on low-temperature intake refrigerant and also by relying on air for additional heat dissipation, thereby enhancing the heat exchange effect.
