[0028] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. Additionally, it should be noted that for the sake of description, only parts related to the present invention are shown in the drawings, rather than all structures.

[0029] Figure 1 It is a schematic structural diagram of a thermal management system provided in Embodiment 1 of the present invention, Figure 2 It is another schematic structural diagram of a thermal management system provided in Embodiment 1 of the present invention, Figure 3 It is still another schematic structural diagram of a thermal management system provided in Embodiment 1 of the present invention. Referring to Figures 1 - 3 , the thermal management system includes: a refrigerant circuit and a water circuit; the refrigerant circuit includes a compressor module 10, a condenser WCC, a liquid storage tank RD, a first electronic expansion valve EXV1, and a cooler CH. The compressor module 10 includes two compressors C1, C2 or a double-headed compressor (two compressors C1, C2 share a controller and a motor rotating shaft, which is called a double-headed compressor); wherein, the outlet of the compressor module 10 is communicated with the refrigerant-side inlet of the condenser WCC, the refrigerant-side outlet of the condenser WCC is communicated with the inlet of the liquid storage tank RD, the outlet of the liquid storage tank RD is communicated with the refrigerant-side inlet of the cooler CH through the first electronic expansion valve EXV1, the refrigerant-side outlet of the cooler CH is communicated with the inlet of the compressor module 10, and the water-side of the condenser WCC and the water-side of the cooler CH are communicated with the water circuit.

[0030] Specifically, the inlet of the compressor module 10 sucks in low-temperature superheated gas. The low-temperature superheated gas is compressed by the compressor module 10 and discharged as high-temperature and high-pressure superheated gas. The high-temperature and high-pressure superheated gas flows into the condenser WCC. After being cooled by the condenser WCC, it enters the liquid storage tank RD. The saturated liquid refrigerant flows out of the liquid storage tank RD. After throttling through the first electronic expansion valve EXV1, it becomes a gas-liquid two-phase state and completes evaporation and heat absorption in the cooler CH. Moreover, by adjusting the opening degree of the first electronic expansion valve EXV1, the superheat degree at the outlet of the cooler CH is controlled, and thus the intake superheat degree of the compressor module 10 can be controlled, thereby completing the entire compression cycle.

[0031] The thermal management system provided in this embodiment includes: a refrigerant circuit and a water circuit; the refrigerant circuit includes a compressor module, a condenser, a liquid storage tank, a first electronic expansion valve, and a cooler. The compressor module includes two compressors or a double-headed compressor; wherein, the outlet of the compressor module is communicated with the refrigerant-side inlet of the condenser, the refrigerant-side outlet of the condenser is communicated with the inlet of the liquid storage tank, the outlet of the liquid storage tank is communicated with the refrigerant-side inlet of the cooler through the first electronic expansion valve, the refrigerant-side outlet of the cooler is communicated with the inlet of the compressor module, and the water-side of the condenser and the water-side of the cooler are communicated with the water circuit. In the thermal management system provided in this embodiment, the compressor module includes two compressors or a double-headed compressor. Compared with the traditional single-stage compression, under the working condition of a large pressure ratio load, the two compressors share the load, reducing the load on a single compressor, enabling each compressor to operate within a comfortable pressure ratio range, thereby improving the operating efficiency of the compressor and effectively enhancing the system performance.

[0033] This embodiment is based on Embodiment One. Refer to Figures 1 - 3 , optionally, the compressor module 10 includes a first compressor C1 and a second compressor C2.

The discharge port of the first compressor C1 is communicated with the suction port of the second compressor C2.

[0034] Specifically, the low-temperature superheated gas sucked in at the inlet of the compressor module 10 is compressed by the first compressor C1 and discharged as medium-temperature and medium-pressure gaseous refrigerant. The medium-temperature and medium-pressure gaseous refrigerant flows into the suction port of the second compressor C2. After being compressed by the second compressor C2, it is discharged as high-temperature and high-pressure superheated gas. The high-temperature and high-pressure superheated gas flows into the condenser WCC. Compared with the traditional single-stage compression, under the working condition of a large pressure ratio load, the two compressors share the load, reducing the load on a single compressor, enabling each compressor to operate within a comfortable pressure ratio range, thereby improving the operating efficiency of the compressor and effectively enhancing the system performance.
