Patent ID: 7391610

Claim:
An electronic module installation comprising: a metal chassis defining at least one slot adapted for receipt of an electronic module, said chassis comprising an exposed metal region of a rear wall that defines a heat input region to the chassis; an electronic module operatively installed in said at least one slot, said module comprising a cover assembly defining an interior space in which a printed circuit board with electronic components is received, said cover assembly including a thermal pathway that comprises: (i) a heat channel; (ii) a chimney that includes a base that lies closely adjacent and that is thermally coupled to at least one of said electronic components; and (iii) a projecting tail portion that is spaced from said chimney and at least partially defines a heat output block, wherein said heat output block lies closely adjacent and is thermally coupled said heat input region of said metal chassis, wherein said base of said chimney conducts heat from said thermally coupled electronic component into said heat channel and wherein said heat output block conducts heat from the heat channel to said chassis through said heat input region.
