Description
A novel gas thermal switch is designed and tested in this paper. This thermal switch would be considerably useful in the cryogenic devices with cryocooler, especially for the helium free devices. It can cut off the conduction path with a simple and low cost design. It has an active operation mechanism driven by normal gas. The fine calculated switch gas type and amount can drive the thermal switch off with the instinctive heat load through CH itself.
A test rig with this thermal switch is built and several tests are conducted to verify the performance. The design principle and the test results will be presented in this paper.
