technical field

The invention belongs to the field of charging bins for electric vehicles, and in particular relates to a cooling system used in charging bins.

Background technique

At present, the heat dissipation of the charging and discharging motor and the charging bin is basically carried out separately. The heat dissipation of the charging and discharging machine mainly adopts forced air cooling and water cooling. The forced air cooling mainly uses a fan to directly dissipate heat from the heating module of the charging machine. Its main advantages are low cost and mature technology, but it has low heat dissipation efficiency, large noise, Disadvantages such as poor thermal control effect and large space occupation; water cooling is to directly attach the water cooling plate to the surface of the heat dissipation module, and take away the heat through the forced convection of the liquid in the water cooling plate to achieve the effect of cooling. The advantages of this heat dissipation mode are: low thermal resistance, high heat dissipation power, and the coolant is not affected by gravity. Under the action of the water pump, it can dissipate heat to any module. The charging compartment mainly uses the air conditioner to dissipate heat. Its main advantages are convenient installation and use, safety and reliability, but it also has problems such as poor heat dissipation efficiency and low thermal control effect, and the charging and discharging machine and the charging compartment are separated for heat dissipation, which requires different equipment. , takes up a lot of space, high cost and inconvenient to control.
