Abstract: The present disclosure includes a method for regenerating power in an information handling system. The method includes circulating a cooling fluid through a fluid flow loop connecting a thermosiphon, a turbine, and a condenser. The method further includes removing heat from a heated component of the information handling system, converting the cooling fluid from a liquid state to a gaseous state in the thermosiphon, and extracting energy from the cooling fluid in the gaseous state in the turbine. The method additionally includes removing thermal energy from the cooling fluid in the condenser, converting the cooling fluid from a gaseous state to a liquid state as the thermal energy is removed from the cooling fluid, and returning the cooling fluid in the liquid state to the thermosiphon. The disclosure also includes associated systems and apparatuses.

Abstract: A power regeneration system for use with an information handling system is disclosed. The power regeneration system may include a thermosiphon in thermal communication with a heated component of the information handling system, a turbine, a condenser, and a fluid flow loop. The thermosiphon may be configured to convert a cooling fluid from a liquid to a gaseous state as the cooling fluid absorbs heat from the heated component of the information handling system. The turbine may be configured to extract energy from the cooling fluid in the gaseous state after it leaves the thermosiphon. The condenser may be configured to remove thermal energy from the cooling fluid after it leaves the turbine, the condenser fluid converting the cooling fluid from a gaseous state to a liquid state as thermal energy is removed. The fluid flow loop may connect the thermosiphon, the turbine, and the condenser in order so that the cooling fluid flows in a closed loop through the power regeneration system.
