How to design the cooling system and piping of induction heating equipment?

The piping materials should use copper pipes and stainless steel pipes as much as possible to prevent iron filings from entering the spare parts; the inlet and outlet pipe diameters should be designed according to the actual inlet and discharge volumes. The water inlet pipe is a pressure pipe, and the water outlet pipe has two types: a closed water return pipe and a self-pressure water return pipe. The former has pressure, and the pipe diameter can be relatively small, while the latter has no pressure, and the pipe diameter is much larger; the cooling water should avoid contact with air , so as not to reduce the cooling effect of water due to the presence of air bubbles in the water, especially for inductors with high current density.
