# Thermal contact conductivity¶

The thermal contact conductivity is the proportionality constant that links the heat flow to the temperature difference using the equation [1]. Use the thermal contact conducitivity for links with where two bushing or a bushing and a moving interface are linked.

$Q = TCC * (T_2 - T_1) [1]$
