thermal conductance

Noun

 * 1)  A measure of the ability of a particular body or assembly to conduct heat.

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:


 * $$P{_t}{_h} = C{_t}{_h} \times \Delta T$$

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:


 * $$C{_t}{_h} = \lambda \ \frac{A}{d}$$

The multiplicative inverse of thermal conductance is thermal resistance, denoted as Rth.
