Thermal Resistance Calculator
Overview This calculates a measurement of a temperature difference between two materials and their ability to resist the flow of heat. Rwall = Thermal resistance for conductive heat transfer through a plane wall (K/W) x = Thickness of a plane wall k = Average thermal conductivity A = Heat transfer area
To calculate for a plane wall:
$$Rwall = x/kA$$
Knowing the thermal resistance between two components of a device will calculate for temperature differences.
