Auxiliary-cooled electronics assembly with extruded cooling cavity

Abstract:

An auxiliary-cooled electronics assembly comprises a metal extrusion that includes: one or more cooling conduits extending axially along a length of the metal extrusion with a first open end in fluid communication with the cooling conduit(s); and a second open end in fluid communication with the cooling conduit(s); a first end cap coupled to the first open end forming a fluid-tight seal between the first end cap and the metal extrusion; a second end cap coupled to the second open end forming a fluid-tight seal between the second end cap and the metal extrusion; and one or more electrical circuit components, electrically linked together to form an electrical circuit, mounted to the metal extrusion.
