thermal conductance
English
Noun
thermal conductance (plural thermal conductances)
Usage notes
The heat (thermal energy) flow Pth through a given body depends on the thermal conductance Cth of that body, and the temperature difference ΔT over it, and follows the formula:
Thus, the higher the conductance, the higher the heat flow. The unit of thermal conductance in SI system of units is W·K−1. For the special case of an ideal plate with area A, thickness d and thermal conductivity λ, the thermal conductance of the plate is:
The multiplicative inverse of thermal conductance is thermal resistance, denoted as Rth.
