HIGH THERMAL CAPACITY HEAT SINK

Abstract

A heat sink for cooling a heat generating device comprises: a housing, comprising: a heat transfer block for receiving heat from the heat generating device; and side walls, extending from the heat transfer block, the heat transfer block and side walls together defining an internal volume for receiving a coolant from external the heat sink; and a plurality of heat pipes and/or vapour chambers, each heat pipe and/or vapour chamber extending from the heat transfer block within the internal volume. A cooled electronic system comprises: an electronic device that generates heat in use, heat being dissipated from the electronic device through an external surface of the electronic device; and the heat sink, having the heat transfer block mounted on the external surface of the electronic device.
