A recently granted patent (Publication Number: US12004329B1) discloses an innovative apparatus and system for efficient heat removal using a unique pumping apparatus. The apparatus comprises a driver with two chambers separated by a moveable barrier, a pump, and a compressor. The driver alternately expands and contracts the chambers in response to a pressure differential of a gaseous coolant, generating a mechanical force. The pump and compressor, mechanically coupled to the driver, pump liquid coolant and compress a second coolant, respectively. The system includes two thermodynamic cycles driven by the pump and compressor, removing heat from different fluid streams using the respective coolants.

The patent further details the components and operation of the system, including condensers, heat exchangers, and evaporators for efficient heat removal. The system is designed to remove heat from waste heat generating systems and other sources using environmentally friendly coolants with low global warming potential. Additionally, the system includes a third cooling loop with microchannel heat exchangers for heat removal from computer processors in data centers. The method outlined in the patent involves producing mechanical force from a gaseous coolant pressure differential, pumping liquid coolant in a thermodynamic cycle, and compressing a second coolant in another cycle for effective heat removal from different fluid streams. Overall, the patent presents a comprehensive and innovative approach to heat removal systems with a focus on efficiency and environmental sustainability.
