As electronic devices develop rapidly toward high-power densities and miniaturization, waste heat, as inevitable byproducts, significantly influences the electronic apparatus and even induces malfunction and degradation of electronics. Recently, the room-temperature gallium-based liquid metal has been expected to be an ultra-high potential extreme thermal management coolant, mainly due to its superior thermal conductivity, high boiling point, low viscosity, and non-toxicity. However, its cooling capacity is significantly limited by the pumping method. The high electrical conductivity enables the liquid metal to be driven by electromagnetic force. This work developed a high-performance electromagnetic induction pump driven by rotating permanent magnets, which is then combined with the mini-channel heat sink and could dissipate a heat flux of up to 242 W/cm2. It also introduced the liquid metal thermal grease to reduce the thermal contact resistance efficiently. This work provides a powerful cooling strategy for thermal management of electric devices with a considerable heat power and high heat flux.[展开] ...
