Abstract:
A conduction cooled electronic card module comprising:(a) a convection cooled circuit card designed for mounting in a convection cooled card module chassis of an electronic device, the card having a front surface carrying at least a part of said electronic components, a rear surface and edge areas free of said components, wherein at least one of the edge areas has a plurality of thermal vias formed therethrough from the front surface to the rear surface; and (b) a thermally conductive frame carrying said circuit card and having a front surface in direct contact with said part of the electronic components and with said front surface of the circuit card at least at edge areas thereof including the edge area having the plurality of thermal vias such that at least some of the thermal vias are in direct contact with the thermally conductive frame; such that said frame is adapted for conducting heat generated by said electronic components, via the edge areas of the front surface and at least some of the thermal vias to said edge areas of the rear surface of the circuit card, and wherein said module is adapted for the insertion in a chassis designed for conduction cooled card modules, by means of said frame, so that said edge areas of the circuit card and at least some of the thermal vias are received in said chassis in thermal contact therewith to transfer to the chassis heat generated by electronic components of the module.
