Abstract

The invention discloses a liquid-cooling circulating DC charging pile system, and solves the problems that a conventional device is large in size, is low in efficiency and is big in noise. The systemincludes a liquid-cooling circulating device, a charging module, and a monitoring module. The monitoring module is configured to monitor the power of the charging module and the temperature of the liquid-cooling circulation device, control the flowing and stopping of cooling liquid in the liquid-cold circulating device, and adjust the flow rate of the cooling liquid; the charging module is used tocharge an electric vehicle; the liquid-cold circulation device is used for conveying and returning the cooling liquid, and cooling the charging module through the heat dissipation function of the cooling liquid. The monitoring module monitors the charging module and feedbacks the adjustment of the liquid-cooling circulating device. The system has the advantages of high refrigeration efficiency and energy conservation, effectively prevents corrosion caused by liquid, effectively reduces noise, effectively reduces the size of a device, and improves power density.

Description

technical field [0001] The present application relates to the technical field of electric vehicle charging equipment, in particular to a DC charging pile of a liquid-cooled circulation system. Background technique [0002] The power supply of the charging module is the core component of the DC charging pile, and it is also the main heat source. High temperature will cause the performance of components to change or even fail, which will lead to the failure of the entire DC charging pile. High power density, high power and small volume will inevitably lead to more concentrated and difficult heat dissipation. The charging module is a highly integrated power electronic module. The traditional air-cooled heat dissipation cannot guarantee complete sealing, and the entry of small dust particles into the module will affect the product life. The use of a large number of fans can also create noise. The life of the fan also restricts the stability of the system. Therefore, it is urge...
