How to solve the huge heat problem of induction melting capacitors?

Since the induction meltinging 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 disspitation 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.

What are resonant functions here in the induction heating/melting power system? 1. Clear off high leakage inductance 2. Adjust the input frequency 3. The formed tuned network could reduce the harmonic content, minimizing the generated  electromagnetic interference(EMI).The basic function for induction heating resonant capacitors? 1. Store a significant of reactive power 2. Handle high voltage, high current 3. Low losses for preventing overheating and capacitor failure.
