In this numerical study, we investigated the performance of heat sink used in the inverter of industrial generator. The heat release performance was evaluated with heat input from the heat source, air flowrate of the fan, and ambient air temperature. We set the standard condition on the basis of regular power consumption of chips in the inverter as a 100% heat input, an actual operating flowrate of the fans, ambient air temperature of 298K, and 6 ㎜ spacing between fins. Heat inputs to the heat sink were varied from 100 to 50 % of standard condition. But the portion of heat release thru the heat sink, 89.8%, remains almost the same for the three cases, 100, 75, 50% heat inputs. The other 10.2% of heat was release to ambient thru the natural convection and radiation transfer. While, we changed the air flowrate to the heat sink as 75, 100, and 125%, and the portions of heat release thru the heat sink were 87.7, 89.8, and 91.2%, respectively. Also, the temperature of air flow into the heat sink was varied. In case of 293K, the heat release portion was almost same as that of the standard case, 298K. But the case of 303K, 5K higher than the standard condition, the portion of heat release thru the heat sink was 4% lower than that of standard condition.
