Thermal Resistance Heat Sink Calculation
Thermal Resistance Heat Sink Calculation . • rθcs = thermal resistance of the thermal interface material, (tim), used between device and heat sink • rθsa = thermal resistance of the heat sink to the ambient (surrounding air). This calculator assumes 1°c/w for the thermal resistance of the resistor body to the heat sink case. Comparison and Evaluation of Power Factor Correction Topologies for from file.scirp.org The following equation is used to calculate r hs, the thermal resistance of the heat sink: Ap = 0.1 x 0.1 = 0.01 m 2. 6 obtaining heat sink thermal resistance value:
