Abstract

Heat exchangers (14) with metallic or copper deflector plate (12), are connected in series or parallel to an iron core (11). A fluid conduit (13) with tube walls (13a-13d) extended from the plate in U-shaped fashion, is operationally connected to the iron core, to remove heat emitted from the iron core.
