Abstract: A heat-activated pump removes waste heat from electronic components, at a data center, circuit board, or chip level. A set of evaporators receive heat from the electronics, converting a working fluid into vapor. Piping from the evaporators to a shared condenser(s) and back form a fluid circulation system. A pressure-control valve set for a specified electronic operating temperature allows vaporized working fluid to vent into a liquid-piston chamber, where it expands adiabatically, displacing pumped liquid in a pumping stage and expelling it from the chamber through a unidirectional valve to the shared condenser(s). The condenser(s) has a heatsink transferring heat away to a flow of cooler fluid. The pumped liquid returns in a suction cycle to the chamber through another unidirectional valve. An injector valve returns jets of condensed working fluid to the evaporator in successive brief spurts responsive to periodic pressure pulses in the chamber.

Abstract: A technique and corresponding device to provide for a floating heat sink is disclosed. The technique includes a method that allows for insertion of an electronic component (e.g., an optical transceiver) into a cage that has a pre-installed heatsink. At the beginning phases of insertion, no friction is present between the electronic component and the heatsink. At or very near an insertion end phase (the electronic component is almost fully inserted), an actuator (e.g., roller or button) is impacted to impart a pivot motion via a lever arm to cause lowering of the heatsink toward the electronic component. A thermal interface material (TIM) may therefore be present to establish a thermal coupling between the heatsink and the electronic component. The TIM and heatsink contact the electronic component via a downward motion (caused by the pivot) to provide a nearly frictionless sliding impact to the TIM.

Abstract: The disclosure provides a cooling device, for cooling devices that generate heat during their operation.

The cooling device may be used as part of an electronic rack, a data center, and in other environments.
