AI Technical Summary
Technical Problem
Existing charging stations struggle to effectively control temperature under high power density and high heat flux density, resulting in insufficient heat dissipation that affects charging efficiency, or excessively low temperatures that prevent the equipment from starting normally.
Method used
A liquid cooling system was designed, which uses parallel cooling and heating cycles and temperature sensors and heaters to control the switching of fluid between different channels to achieve rapid cooling or heating and ensure that the power module temperature is within the normal range.
Benefits of technology
It enables rapid cooling or heating, avoiding equipment failures caused by excessively high or low temperatures, and ensuring charging efficiency and safety.

Abstract
The present application relates to liquid cooling heat dissipation technical field, specifically propose a kind of liquid cooling cooling system of charging pile, comprising: liquid cooling part, transfer part and heat removal part;Liquid cooling part is set on power module, and it is provided with flow channel for fluid passing in it;Transfer part is provided with transfer cavity for fluid passing, and the water inlet of flow channel is communicated with transfer cavity, and the water outlet of flow channel and transfer cavity are connected in parallel with first channel and second channel;Heating assembly is provided in transfer cavity;Heat removal part is set on first channel;When the temperature of fluid is higher than first preset temperature, first channel opens, and second channel closes;When the temperature of fluid is lower than second preset temperature, second channel opens, and first channel closes.Overcome the problem of waiting for temperature to rise, avoid the temperature of power module too low and cannot normally start, improve cooling efficiency, also can avoid temperature too low, so as to maintain the temperature of power module in normal range, to ensure charging efficiency.
