The invention relates to an active cooling system for a battery pack of a new energy automobile. The cooling system comprises a cooling subsystem and a power generation subsystem which are electrically connected. Wherein the cooling subsystem comprises a semiconductor chilling plate, and the semiconductor chilling plate comprises a cold end and a hot end; the power generation subsystem comprises two motors which are fixed together, output shafts of the two motors face opposite directions, the output shafts of the two motors are provided with through holes in the axial directions of the output shafts, flywheels rotating in one direction are arranged in the through holes, lead screw nuts are arranged on the flywheels, and lead screw shafts forming a ball screw pair with the lead screw nuts are arranged on the lead screw nuts; according to the new energy automobile battery pack, electric power is generated by using bumping in the automobile running process as power, so that the semiconductor chilling plate can generate low temperature, air entering the battery pack is cooled, the cooled air is used for air cooling of the battery pack, the new energy automobile battery pack can be used as usual in summer, and the use safety of the battery pack is improved.

    本发明涉及一种新能源汽车电池包主动降温系统。该降温系统包括电连接的冷却子系统和发电子系统;其中,冷却子系统包括半导体制冷片,半导体制冷片包括冷端和热端;发电子系统包括两个固定在一起且输出轴朝向相反的电机,两个电机的输出轴设有沿输出轴轴向的通孔,通孔内设有单向转动的飞轮,飞轮上设有丝杠螺母,丝杠螺母上设有与其组成滚珠丝杠副的丝杠轴;本发明通过利用汽车行驶过程中的颠簸作为动力来产生电力,使得半导体制冷片能够产生低温,将进入到电池包内的空气冷却,利用冷却的空气对电池包进行风冷,使得新能源汽车电池包在夏季时能够照常使用,提高了电池包使用安全性。
