The project proposes thermal management systems for batteries, power devices on electric vehicles, allowing efficient cooling/heating, low power consumption to increase driving range on a single charge, lightweight and compact, requires little to no maintenance. Specifically, we will develop: (1) a closed-loop heat pipe that can transmit large amounts of heat in thin thickness using a new multilayer capillary structure; (2) a closed-loop heat pipe capable of cooling from many sides of the heat source, high heat load, long heat transfer distance; (3) an injection flow system using a new heat sink structure combined with liquid additives to increase heat transfer efficiency and reduce energy consumption.
