Hybrid cooler to thermally cool semiconductor devices inside and outside a chip package

An apparatus is described. The apparatus includes a chip package cooling assembly chamber having one or more features to receive one or more heat pipes that receive heat generated by one or more semiconductor devices that reside outside the chip package. In detail, the heat pipes that are thermally coupled to the VR FET heat sinks are attached to the outside of the cold plate (again, they can be screwed to the cold plate with a thermal interface material between them). Thus, heat generated by the VR FETs is transferred to the VR FET heatsinks and the chip package cold plate via the heat pipes. The heat is then transferred to the fluid while it runs through the cold plate and is removed from the system by the fluid as it exits the outlet.

Mitigation of seismic event effects on liquid immersion cooling systems

In some embodiments, an immersion cooling system comprises a spring damper, a crumple block, a frictional layer, and/or preloaded spring-based mounts to mitigate the effects of seismic events. In other embodiments, the combined mass of liquids in the immersion tank and a compensation tank is kept constant to maintain the system's response to seismic events. In still other embodiments, an immersion cooling system comprises a tunable mass to provide an active response to seismic events. In yet other embodiments, an immersion tank is located within a housing pallet and is moveable within the palette. Spring dampers dampen tank movement within the pallet and shutoff switches housed in the pallet cause power to components in the tank to be shut off in response to tank movement. Cooling liquid can be transferred from the tank to a secondary reservoir to avoid cooling liquid loss and protect the tank.
