The invention provides a refined monitoring device and method for air cooling heat dissipation of a direct-current charging pile. According to the invention, the temperature difference between the airinlet temperature and a charging module is monitored in real time; PWM with different duty ratios is dynamically output according to the temperature difference to control the air speed of a heat dissipation fan to dissipate heat; the purposes of energy conservation and emission reduction are achieved; the actual wind speed of the charging pile is monitored through a wind quantity sensor; and theactual running state of the heat dissipation fan is judged by comparing the actual wind speed with the set wind speed, so that when the air outlet is blocked or the heat dissipation fan is damaged, operation and maintenance personnel can be informed in time to perform onsite maintenance, safety accidents are avoided, a traditional regular inspection mode is changed, and the labor cost is reduced.

    本发明提供了一种直流充电桩风冷散热精细化监控装置及方法,本发明通过实时监测进风口温度与充电模块的温度差,并根据温度差动态输出不同占空比的PWM来控制散热风机的风速进行散热,以达到节能减排的目的,另外通过风量传感器监测充电桩的实际风速,并根据实际风速与设定风速进行对比,判断散热风机的实际运行状态,从而当出风口发生堵塞或者散热风机发生损坏时,可及时通知运维人员进行现场检修,避免安全事故的发生,改变了传统的定期巡检模式,降低了人力成本。
