Description

Technical Field

[0001] This utility model relates to the field of charging pile power cabinet technology, and in particular to a liquid-cooled charging pile power cabinet. Background Technology

[0002] As the number of electric vehicles on the road increases, the requirements for the construction of charging stations are also becoming more stringent. Among these requirements are increasingly higher charging speeds, reflected in both the demand for cables and battery packs, and the need for effective heat dissipation within the charging station system.

[0003] Under current technological conditions, charging pile systems mostly use air-cooling systems for cooling. Air is introduced into the cabinet through a cooling fan, and the air passes through the heat-generating components inside the cabinet and carries away the heat. The air is then discharged outside the cabinet through the air outlet, thereby achieving the purpose of cooling.

[0004] The disadvantages of this air-cooled system are: 1. The cabinet needs sufficient air intake and exhaust area, which reduces the cabinet's protection level; 2. It has poor heat dissipation effect on high-power charging piles. During operation, the heat generated by the components increases with the increase in charging speed and power, affecting the stable operation of the internal components of the charging pile; 3. The need to remove more heat requires more fans or higher fan speeds, resulting in noise pollution. This application is proposed to address these shortcomings. Utility Model Content

Liquid cooling is highly efficient and has low noise, avoiding noise pollution problems.
