Calculation of heatsink |
|
P = DT / [RTH(j-c) + RTH(c-a)] P = Expressed in W DT = Difference between maximum working temperature (125°C) and room temperature RTH(j-c) = Thermal resistance of the component RTH(c-a) = Thermal resistance of the heatsink and quality of fastening device Example: Ambient Temperature 30°C, Power Rating: 70W 1) P = DT / [RTH(j-c) + RTH (c-a)] 2) DT = 125°C - 30°C = 95 K 3) [RTH(j-c) + RTH (c-a)] = DT / P = 95K / 70W = 1,36K/W4) RTH (c-a) = 1,36K/W - 1K/W = 0,36K/W |
