Thermal contact conductance

That is, thermal contact resistance is the inverse of thermal contact conductance. Usually, thermal contact conductance is reported in the jiterature, but the concept of thermal contact resistance serves as a better vehicle for explaining the effect of interface on heat transfer. Note that represents thermal contact resistance per unit area. The thermal resistance for the entire interface is obtained by dividing by the apparent interface area/t.

Effect of metallic coatings on thermal contact conductance (from Peterson). 

There is considerable uncertainty in the contact conductance data reported in the literature, and care should be exercised when using them. In Table 3-2 some experimental results are given for the contact conductance between similar and dissimilar metal surfaces for use in preliminary design calculations. Note that the thermal contact conductance is highest (and thu.s the contact resistance is lowest) for soft metals with smooth surfaces at high pressure.

A 1-nun-thjck copper plate (fc = 386 W/m °C) is sandwiched between two. 3-mm-thick epoxy boards (it = 0.26 W/m °C) that are 15 cm X 20 cm in size. If the thermal contact conductance on both sides of the copper plate is estimated to be 60(X) W/m °C. determine the error involved in the total thermal resistance of die plate if the thermal contact conductances are ignored. 

When steady-state conduction occurs within and outside solids, or between two contacting solids, it is frequently handled by means of conduction shape factors and thermal contact conductances (or contact resistances), respectively. This chapter covers the basic equations, definitions, and relationships that define shape factors and the thermal contact, gap, and joint conductances for conforming, rough surfaces, and nonconforming, smooth surfaces.
