How to solve the huge heat problem of induction melting capacitors?
Since the induction melting capacitors are working under high ripple current and high temperature, the huge heating will be generated during the operation. Thus the heat dissipation is of great importance. The induction heating & melting capacitors are mostly designed with cooling water tubes which enhance the capacitor performance, as well as its reliability. The capacitor with good heat dissipation will extend its lifespan, likewise capable of carrying higher power.
Furthermore, there are many other cooling methods, like self-cooling, forced ventilation.
The simplest way for cooling capacitor is providing enough space around the capacitors. Normally, it is largely insufficient for cooling down the capacitor. In super high power projects, the larger heat load may need additional cooling system, such as an external heat dissipator.
