Improvement direction of AC to DC Power Module
Improvement and optimization of heat dissipation methods. For Power Module, the failure rate of charging piles and noise nuisance are two major problems. The failure rate of charging stations directly affects the profitability of the site and the user experience. The main reason for the failure of charging stations is the failure of the charging module.
The current mainstream heat dissipation mode is the direct air cooling mode, which uses a high-speed fan to exhaust air. The air is sucked in from the front panel and discharged from the rear of the module, thereby taking away the heat of the radiator and the heating device. However, the charging pile is in an outdoor environment, and the air will be mixed with dust, salt spray and water vapor and adsorbed on the surface of the internal components of the module. The internal dust accumulation will cause the system insulation to deteriorate, the heat dissipation to deteriorate, the charging efficiency to be low, and the equipment life to be reduced; in the rainy season or humidity, the dust will absorb water and become moldy, corrode the device, and short-circuit and cause module failure. Secondly, the air cooling mode uses a high-speed fan to exhaust air, and the cooling fan of the charging stastions will generate a lot of noise. Therefore, in order to reduce the failure rate and noise of the AC to DC power module, it is necessary to improve and optimize the air cooling mode.
