Abstract:
A circuit device comprising:a printed circuit card having a substantially planar card body comprised of insulative material and having a plurality of pads mounted along at least one edge thereof, said card having a pair of major surfaces and at least one electronic module mounted on each of said major surfaces in connection to one or more of said pads; anda heat exchanger including a flexible, thermally conductive strip having a first area affixed in thermally conductive contact to a surface of at least one electrical module on one of said major surfaces and a second area affixed in thermally conductive contact to a surface of at least one electrical module on the other of said major surfaces, said strip extending from its attachment to at least one module on said one major surface in spaced relation around a given edge of said card and into attachment to at least one module of said other major surface, and said strip being spaced from said given edge in an arched arrangement forming an open loop portion beyond said given edge so as to increase the area of said strip exposed to the ambient and to facilitate cooling of both sides of said strip in said open loop portion.
