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.

Abstract: A cold plate is configured to use isolated primary and secondary liquid coolants and comprises: a thermally conductive body defining an internal volume and arranged for mounting with respect to an electronic device, so as to transfer heat from the electronic device to the internal volume; a coolant inlet for receiving the secondary liquid coolant into the internal volume to receive the transferred heat; and a coolant outlet for the secondary liquid coolant to flow out of the internal volume. The thermally conductive body is configured to define an external receptacle having a volume arranged to receive and retain the primary liquid coolant for heat transfer between the primary and secondary liquid coolants. The cold plate may form part of a system for cooling electronic devices.

Abstract: A cold plate, comprises: a housing having a surface providing a thermal interface for cooling an electronic device; a channel within the housing proximate to the surface for a liquid coolant to flow therethough such that heat received by the thermal interface is transferred to the liquid coolant; and a coolant port extending outside the housing, for transferring liquid coolant to and/or from the channel. A cross-sectional area of an outlet from the coolant port to the channel may be no larger than that of the channel at the outlet. Pins and/or fins may be arranged within the channel adjacent to the coolant port. The coolant port may cause liquid coolant to enter and/or exit the channel in a direction perpendicular to the surface. The coolant port may comprise an independent rotating fluid connector thereby allowing adjustment in the direction of a pipe coupled to the coolant port.
