Flexible Thermal Link for Space Based Cryocooler: A review

Flexible Thermal Link plays very crucial role in the cryogenic component for transfer the heat. The purpose of these links is to provide a means of transfer the heat from a hot surface of cryocooler to the cold reservoir. Because of high heat dissipation component in cryocooler, skin temperature of cryocooler increases and it can be reason for lowering performance and reduce its life during work in satellite. Therefore flexible thermal link should be good in thermal performance in other low thermal resistance and also should have enough flexibility. This could maintain skin temperature of cryocooler and resist the vibration which comes on the cryocooler in satellite. Also flexible thermal link should have its flexibility, durability, and mass constraints. The present states of developments of flexible Thermal Links for space based cryocooler are reviewed in this paper. In the past years new research on these flexible thermal links has developed to vitally improve them and make suitable for even more applications.
