Fig. 14 is a schematic structural diagram of an evaporator of a driving module according to an embodiment of the present application. As shown in fig. 14, the evaporator 430 includes a plurality of evaporation fins 433 thereon; wherein, gaps 434 are formed among the evaporation fins 433, so that the circulation air ducts can be communicated. By providing evaporator 430 in a configuration that includes a plurality of evaporation fins 433, this facilitates airflow through evaporator 430; in addition, the surface area of the evaporator 430 can be increased, so that the cooling area of the evaporator 430 can be enlarged, and thus, a longer stroke can be provided when the air flow passes through the evaporation fins 433, thereby improving the heat exchange efficiency of the air flow.

The expansion valve 440 may be an electronic expansion valve, or may be other expansion valves, for example: the thermostatic expansion valve 440, etc., and in the present embodiment, the type of the expansion valve 440 is not particularly limited.
