摘要： The present disclosure is directed to systems and methods of improving the thermal performance of processor-based devices. Such thermal performance improvement may include limiting the degree of tilt experienced by a semiconductor device as a thermal solution coupled to the semiconductor device is tightened to the substrate. Such thermal performance improvements may include increasing the available heat transfer area associated with a particular heat producing semiconductor device. Such thermal performance improvements may include thermally coupling one or more cool blocks thermally coupled to one or more remote heat-producing devices to a central cool block that may be cooled using a cooling medium or coupled to a central heat-producing semiconductor device.

摘要： 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.

摘要： Methods and apparatus for an autonomous stage-switching multi-stage cooling device are disclosed are disclosed. A disclosed example coolant distribution unit (CDU) includes an enclosure, an inlet and an outlet of the CDU to be fluidly coupled to a cooling block associated with a heat generating source, at least one sensor to measure a first temperature corresponding to the inlet and a second temperature corresponding to the outlet, and a plurality of valves to be controlled by a controller to control a flow of fluid from the inlet to at least one of an ambient cooler or a sub-ambient cooler based on: (i) a comparison of the first temperature to an ambient temperature and (ii) a comparison of the second temperature to a target temperature.
