thermal conductance

== English == === Noun === thermal conductance (countable and uncountable, plural thermal conductances) (physics) 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 × Δ T {\displaystyle 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 = λ A d {\displaystyle C{_{t}}{_{h}}=\lambda \ {\frac {A}{d}}} The multiplicative inverse of thermal conductance is thermal resistance, denoted as Rth. ==== Related terms ==== thermal conductivity ==== Translations ====
