Abstract: Examples described in this disclosure relate to waste cold recuperation in fuel cell based power generation systems for datacenters. An example waste cold recuperation system includes a liquefied gas storage for supplying liquefied gas as a coolant to cool a first set of compute resources configurable to operate in a first cryogenic environment. The system is configurable to supply at least some of the vapor phase of the liquefied gas as a coolant to cool a second set of compute resources configurable to operate in a second cryogenic environment, resulting in the at least some of the vapor phase of the liquefied gas becoming a super-heated vapor phase of the liquefied gas. The system is configurable to supply the super-heated vapor phase of the liquefied gas as fuel to fuel cells for providing electrical power to a datacenter load including compute resources configurable to operate in a non-cryogenic environment.

Abstract: A thermal management system includes a high-pressure (HP) container, a low-pressure (LP) container in fluid communication with the HP container and having a fluid pressure less than the HP container, and a two-phase working fluid partially in the HP container and partially in the LP container. The two-phase working fluid has a vapor phase and a liquid phase. A pump is configured to move the working fluid through the system, and a condenser is configured to condense the vapor phase of the working fluid into the liquid phase.

Abstract: Techniques for dynamically changing a pressure within a pressurized cooling system to thereby allow different cooling rates to be used to cool electronic equipment are disclosed. A pressurized cooling system cools electronic heat generating components using dielectric heat transfer fluid disposed within a two-phase immersion cooling container. This container is operable to maintain different pressure levels. The pressurized cooling system includes a pressure system structured to modify a pressure within the container. The system operates in a first state when the pressure is above a threshold pressure. The system operates in a second state when the pressure is at the threshold pressure. The system operates in either one of the first state or the second state based on an operating state of the heat generating component.
