Problems solved by technology

[0002] At present, the heat dissipation of box-type power supplies mainly adopts two methods: air cooling and liquid cooling. Air cooling mainly uses air convection to achieve the purpose of heat dissipation. As a result, the temperature decreases and consumes a lot of energy. When the external environment temperature of the box-type power supply is too high, the convection of the air cannot reduce the temperature
Liquid cooling mainly adopts the direct contact liquid cooling method for cooling and heat dissipation, directly immersing the battery pack of the box-type power supply in the cooling liquid, which has low safety performance

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a box-type power supply non-contact liquid cooling system and a control method. Background technique [0002] At present, the heat dissipation of box-type power supplies mainly adopts two methods: air cooling and liquid cooling. Air cooling mainly uses air convection to achieve the purpose of heat dissipation. As a result, the temperature is reduced and a large amount of energy is consumed. When the external environment temperature of the box-type power supply is too high, the convection of the air cannot reduce the temperature. Liquid cooling mainly adopts the direct contact liquid cooling method for cooling and heat dissipation. The battery pack of the box-type power supply is directly immersed in the cooling liquid, which has low safety performance. Contents of the invention [0003] An object of the present invention is to provide a box-type power supply non-contact liqu...
