Calculation of heatsink |
|
P = DT / [RTH(j-c) + RTH(c-a)] P = Expressed in W DT = Difference between maximum working temperature (155°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: 10W 1) P = DT / [RTH(j-c) + RTH (c-a)] 2) DT = 155°C - 30°C = 125K 3) [RTH(j-c) + RTH (c-a)] = DT / P = 125K / 10W = 12,5K/W4) RTH (c-a) = 12,5K/W - 2,5K/W = 10K/W |
