The invention discloses a small-power direct-current charger fan cooling device and a control method, relates to the technical field of charger cooling, and solves the problems caused by the fact that a fan cannot work and is detached due to poor contact of a fan wire harness connector of a charger. Comprising a charger, a fan controller and a cooling fan. Power flow and information flow interaction is carried out between the charger and the fan controller in a wireless mode, and connecting wire harnesses of an external fan of the charger are reduced. The fan controller collects the temperature of the air outlet and the air inlet of the air duct at the bottom of the charger through the temperature sensor; after the battery charger receives the temperature related data, the temperature related data is compared with the set maximum temperature of the air inlet, the set maximum temperature of the air outlet and the set temperature difference value of the air outlet and the air inlet, and the fan control duty ratio Duty is obtained through calculation; and the fan controller is used for controlling the intelligent speed change of the cooling fan according to the fan control duty ratio Duty, so that the utilization rate of the system power is improved.

    本发明公开了一种小功率直流充电机风扇冷却装置及控制方法,涉及充电机冷却技术领域,解决了充电机因风扇线束接插件接触不良,风扇无法工作以及拆卸带来的问题;包括充电机、风扇控制器和冷却风扇;所述充电机和风扇控制器之间通过无线方式进行功率流和信息流交互,减少了充电机外部风扇连接线束;风扇控制器通过温度传感器对充电机底部风道的出风口和进风口的温度进行采集;充电机接收到温度相关数据后,会与进风口设定最大温度、出风口设定最大温度以及出风口和进风口的设定温度差值进行比较,计算得到风扇控制占空比Duty;风扇控制器用于根据风扇控制占空比Duty,实现对冷却风扇智能变速的控制,进而提升系统功率的利用率。
