Simple and efficient thermal link assembly for cryocoolers

摘要

The thermal connection between a cryocooler cold tip and any object to be cooled (the thermal load) is very often a technical challenge. The allowed mechanical load on the cooler cold finger is generally strongly restricted. It is therefore difficult to design a mechanically anchored thermal link with low induced mechanical load and high thermal conductance. The proposed heat link concept is based on an evaporation/condensation process between the cooler cold tip and the thermal load.
