Basics of Thermal Resistance and Heat Dissipation
Thermal resistance is represented as the quotient of the temperature difference between two given points by the heat flow between the two points (amount of heat flow per unit time). This means that the higher the thermal resistance, the more difficult it is for heat to be conducted, and vice versa. Temperature difference ΔT.
