|
|
| 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 25°C, Power Rating: 10W 1) P = DT / [RTH(j-c) + RTH (c-a)] 2) DT = 155°C - 25°C = 130K 3) [RTH(j-c) + RTH (c-a)] = DT / P = 130K / 10W = 13K/W4) RTH (c-a) = 13K/W - 6,5K/W = 6,5K/W |
