Encapsulated housing for dissipating heat produced by electrical circuits
First Claim
1. Housing for the dissipation of heat produced by electrical circuits, comprising a metallic armature provided in its upper portion with a recess, the bottom of said recess being intended for the attachment of the electrical circuits, and lateral walls of said recess support connections through the intermediary of insulating seals, a cover being disposed at the surface of said recess in such a way as to render it hermetically sealed, and said armature having in a lower portion cooling means for the circulation of at least one cooling fluid, said cooling means comprising a metallic single-piece assembly having lateral walls and separating channels which are arranged in parallel directions and are regularly spaced apart, and said channels having openings formed between the ends of certain of said channels, in such a way as to obtain a circulation network, and two metallic elements disposed on lateral walls of said single-piece assembly so as to seal off the ends of the channels and the openings, the cooling means comprising at least two openings as an inlet and an outlet of the cooling fluid.
