A water-cooled heat dissipation system for an electric vehicle integrated charging compartment

Abstract

The invention relates to a water-cooled heat dissipation system integrated with a charging and discharging motor of an electric vehicle and a charging bin, comprising a water circulation module, a water cooling module and a heat dissipation module. The water cooling module is fixed in the charging and discharging cabinet, and the water circulation module and heat dissipation module are fixed in the charging compartment. The water circulation module is placed on the far right side of the charging compartment; the water cooling module is placed in the charging and discharging machine; the heat dissipation module is fixed on the middle plate between the working room of the charging compartment and the artificial rest room; the water circulation module, the water cooling module and the The heat dissipation modules are connected through water pipes, and the working state of the water cooling system is controlled through pipe valves to form the entire water cooling heat dissipation system. The invention integrates the charging and discharging motor with the water cooling and heat dissipation of the charging compartment, occupies little space, has simple equipment, and is easy to control.

Description

technical field [0001] 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 [0002] 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 ad...
