The selection and application of heat exchangers are crucial in the liquid cooling system of electric vehicle charging stations. The following are several common types and applications of heat exchangers:

plate heat exchanger

Working principle: It is composed of a series of metal sheets with certain ripple shapes stacked together, and heat exchange between the cooling liquid and the external medium is achieved through the flow channels between the sheets.

Application scenario: Suitable for charging pile liquid cooling systems with high space requirements and large flow rates. It has a compact structure and high heat transfer efficiency, and can flexibly combine the number of plates and flow channel forms according to the power and heat dissipation requirements of the charging pile.

tube heat exchanger

Working principle: The tube bundle is composed of pipes, with cooling liquid flowing inside the pipes and external medium flowing outside the pipes, exchanging heat through the pipe walls.

Application scenario: Commonly used for charging stations with high reliability requirements and harsh working environments. Its structure is sturdy, resistant to high voltage and high temperature, and not easy to leak. It is suitable for some occasions with strict safety requirements, such as outdoor high-power charging piles.

microchannel heat exchanger

Working principle: Adopting microchannel structure increases the heat transfer area and improves the heat transfer efficiency. The coolant flows within the microchannel and efficiently exchanges heat with external air or other cooling media.

Application scenario: Especially suitable for electric vehicle charging stations that require high heat dissipation performance and space. It has a small volume and light weight, and can achieve efficient heat dissipation in a limited space. It is commonly used in compact charging stations or high-power charging modules with strict heat dissipation requirements.
