[0068] As shown in Figure 7 , the water pump 7.3 is arranged in the liquid outlet pipeline, which can provide driving power for the cooling liquid in the cooling liquid circulation loop between the heat dissipation assembly and the cold plate assembly, so that the cooling liquid can realize circulating flow in the cooling liquid circulation loop, and ensure that the water cooling heat dissipation assembly can continuously provide water cooling heat dissipation for the power module 5.

[0069] Wherein, the cooling liquid is cooled by the heat dissipation assembly, then flows into the cooling liquid circulation channel of the cold plate assembly through the liquid inlet pipeline, and exchanges heat with the power devices of the power module 5. After the cooling liquid absorbs the heat of the power devices, the cooling liquid in the cold plate assembly is overheated and flows back to the heat dissipation assembly through the liquid outlet pipeline under the action of the water pump 7.3 for heat dissipation and cooling. Thus, the power module 5 can be continuously water-cooled and heat-dissipated.
