Heat Transfer Assembly

Abstract

A heat transfer assembly includes a heat plate coupled to a spring and to a graphite sheet. The spring is at first location corresponding to a heat source in an assembled device. The graphite sheet extends over at least a middle portion of the spring and over portions of the heat plate. The graphite sheet is coupled to a thermal pad positioned above a given surface of the heat source. The spring provides a compressive force on the thermal pad when the device is in an assembled state. The compressive force enhances thermal conductivity between the heat source and the heat transfer assembly. The heat plate may be positioned within and thermally coupled to a cover of the device. Principally by use of the thermal pad, graphite sheet, and thermal plate, heat generated by the heat source is transferred to the cover and then to the external environment.
