Device for protecting and cooling the poles of an electromagnetic inductor

摘要

A device achieves thermal protection and cooling of the poles of an electromagnetic inductor, in particular for an induction furnace. The furnace comprises a plurality of tubes, arranged side by side and substantially coplanar, through which a coolant fluid flows. The connection of the tubes to the inlet and outlet pipes for the coolant fluid is made by a combination of socket and O-rings designed to ensure both electrical discontinuity and leaktightness between each tube and the pipes.
