Study on Temperature Control Design and High Protection of Charger

There are many problems such as air inlet hole is easy to be blocked, external salt spray affects component's life and seeping water affects equipment's performance in the module of fast charger by using air-cooling. The advantages and disadvantages of four temperature control schemes such as air-cooling, heat exchanger, air conditioning and liquid cooling were compared and analyzed in this research. Four new temperature control schemes were designed to solve the high heat dissipation and high protection problem of the fast charger. In these schemes, compressor refrigeration is not required and the main power consumption components are fans. Maximizing the energy saving of products is an outstanding characteristic. The research result has certain guiding significance in the engineering design of fast charger with increasingly miniaturization and high power.
