Development and testing of a novel thermal switch

摘要

A novel thermal switch, named as Double Driving Devices-based Thermal Switch (DDDTSW) will be described. Some details will be focus on the structure and the work principle of this device, as well as something about experiment for the device's work performance and the test result from it will be introduced. In ground testing of using LN2 as cold resource, the DDDTSW demonstrated an "Off' resistance of 2450K/W and an "On" resistance of 6.0K/W. Finally, it is proposed to advance the DDDTSW design to increase the heat conduction, and it's also pointed out this kind of thermal switch has the potential feasibility used in the space cooling system.
