Design and Characteristics of Water Cooled Capacitors
In high-current and high-frequency applications, film/foil, metallized film water cooled capacitors are used for a wide range of induction heating, including filtering and tank circuit applications. The design of these capacitors makes them suitable for high-power, high-current, and high-frequency, such as broadcast transmitter, induction heating, melting, and high-frequency welding systems.
Using sets of small capacitors helps to distribute the heat generated by capacitors. The small capacitors are commonly used in power electronic circuits. Although this solution helps in thermal management, it is not a suitable option for applications with limited space. Capacitors with integrated water cooling systems are suitable for such applications. Using water-cooled capacitors also helps to reduce the cost and the number of capacitor components used.
Film and ceramic capacitors with integrated liquid cooling systems are increasingly becoming popular for high-current applications. The liquids that are commonly used in such systems are water, a mixture of water and chemical solutions, and de-ionized water. Liquid-cooled capacitors are a suitable choice for power electronic circuits with high energy densities. This cooling method is suitable for applications where the ambient temperature does not exceed the value 50℃ with common design.

The Medium Frequency Induction Heating Treatment
The current frequency of the medium frequency induction heating device is usually 500hz ~ 10000HZ. It is suitable for the surface quenching of steel parts with a heating layer depth of 3 ~ 16mm and a large workpiece diameter (20 ~ 500mm), and can also be used for tempering, normalizing, forging billet diheat or melting metal. In the automobile and tractor manufacturing industry, the surface quenching of crankshaft and camshaft parts is mostly heated by medium frequency equipments.
The medium frequency power supply of the medium frequency induction heating device has two kinds: medium frequency generator (machine type medium frequency power supply) and thyristor medium frequency power supply.
Working Principle of Water Cooled Capacitors
Water cooled induction heating uses an alternating magnetic field to generate induced current in a metal conductor, especially in the induction coil and power supply section, and converts this energy into thermal energy to achieve rapid heating. Its main working principle is as follows:
