Descriptions

Gas gap heat switches are generally used to speed up the cool-down process in dilution refrigerators as well as to control thermodynamic cycles in adiabatic demagneti-zation refrigerator.The fundamental principle is by charging or discharging helium gas ((³He或4He) inside a small gap between two copper fingers, heat transfer can turn on or off between these two copper fingers. Lihan provides a series of standard heat switching products for extreme low temperature refrigerators. Tailor design can also be offered upon user request.
