AI Technical Summary

Technical Problem

In an environment with large temperature and humidity changes, the condensation generated during liquid-cooling and cooling dissipation cannot be effectively exported, resulting in damage to the charging module and distribution components, posing safety hazards and affecting reliability and service life.

Method used

A charging module is designed, which includes a liquid-cooled channel and a flow-guiding structure. The flow guide structure includes a liquid joint surface and a surrounding bus channel, a flow guide channel running in the thickness direction of the charging module, and the condensation is exported from the top of the charging module to the bottom. Through the design of the bus channel and the flow guide channel, the rapid export of the condensation is achieved.

Benefits of technology

Effectively prevent condensation from dripping from damaging the charging module and distribution components, improve the reliability and service life of the charging pile, and reduce safety hazards.

Abstract

The present application provides a charging module and a charging pile, which can collect and discharge the liquid collected in the charging pile. The charging module has a cavity, in which a heating device is arranged; the charging module is provided with a liquid cooling channel and a guide structure, and the liquid cooling channel is used to liquid-cool the heating device; the guide structure is isolated from the cavity and the liquid cooling channel of the charging module; along the thickness direction of the charging module, the charging module has a top and a bottom; the guide structure includes a liquid receiving surface arranged at the top of the charging module and a confluence groove surrounding the liquid receiving surface, and the liquid receiving surface is used to receive the condensation generated when the charging module is liquid-cooled; the guide structure also includes a guide channel running through the charging module, and the guide channel has an inlet end located at the top of the charging module and an outlet end located at the bottom of the charging module, and the inlet end of the guide channel is located in the confluence groove. The charging module prevents liquid from entering the cavity to damage the heating device, thereby improving the reliability and service life of the charging pile.
