1、Induction heating power in normal work, the working current is usually up to hundreds of amp, thousands of amp or even thousands of amp, due to work loss, silicon control, capacitor and other devices, will produce a lot of heat, if no timely cooling or cooling effect is poor, the temperature of electrical components will rise sharply to the limit temperature and burn out, capacitor will also cause heat breakdown short circuit, so the cooling system to cool the induction heating equipment.
