Self-Powered Magnetothermal Fluid Pump

Advances in the capabilities of electronics have enabled high power density devices. However, even in light of advances in electronics efficiency figures, the increased power density operational points result in the generation of excess heat. In order to maintain efficiency and to product sensitive components from thermally-induced failure, intelligent rejection of thermal energy is often a critically limiting constraint in system development. Novel concepts for thermal management are particular necessary in applications with finite energy stores, such as long-duration space missions. The Prime Photonics magnetothermal fluid pump provides for game-changing, autonomous self-powered thermal management systems. Our self-powered pump converts excess thermal energy into point-of-use mechanical energy with a low mass insertion penalty. The operational frequency of the pump is proportional to the magnitude of the thermal gradient, supplying additional pump capacity in response to increased thermal loads.
