“…The graph includes results obtained by other groups measuring thermal or electrical resistance. The data in the upper part of the graph correspond to thermal conductance measurements by Berman et al [17] and Salerno et al [18][19][20]. They are clearly well above our data, while following closely, too, a 1/P pressure dependence.…”

The thermal contact conductance is one of the important components in heat transfer mechanism. The accurate estimation of thermal contact conductance is necessary for the development of a conduction-cooled superconducting magnet system because the metallic materials are thermally connected to the refrigerator or heat sink to cool the superconducting magnet without cryogen. The contact resistance occurs at the interface between metals and the amount of conductance can be affected by various factors, such as surface roughness, contact area, and contact pressure. In the superconducting magnet system, there are several metal components in contact with each other for cooling magnet as well as supplying current to the magnet. Therefore, a temperature gradient exists between superconducting magnet and cryocooler. In this study, we have developed the thermal contact conductance measurement system and used the steady state method to measure the thermal conductance between metals. The effects of temperature, contact pressure and interfacial materials on the thermal contact conductance are also discussed.

“…Salemo, P.Kittel, A.L. Spivak (1994) [33] In this paper sample pairs were fabricated from OFHC copper,6061-T6 aluminium, free machining brass and 304 stainless steel. And thermal contact conductance was found to increase with increasing applied force and the addition of indium foil or apiezon grease between the contact surfaces resulted in an improvement over uncoated surfaces ranging from approximately a factor of 3 for stainless steel to an order of magnitude for copper contacts.…”
