@article{(Open Science Index):https://publications.waset.org/pdf/1848, title = {Heat Release Performance of Swaged- and Extruded-Type Heat Sink Used in Industrial Inverter}, author = {Jung Hyun Kim and Min Ye Ku and Gyo Woo Lee}, country = {}, institution = {}, abstract = {In this experiment, we investigated the performance of two types of heat sink, swaged- and extruded-type, used in the inverter of industrial electricity generator. The swaged-type heat sink has 62 fins, and the extruded-type has 38 fins having the same dimension as that of the swaged-type. But the extruded-type heat sink maintains the same heat transfer area by the laterally waved surface which has 1 mm in radius. As a result, the swaged- and extruded-type heat sinks released 71% and 64% of the heat incoming to the heat sink, respectively. The other incoming heat were naturally convected and radiated to the ambient. In spite of 40% decrease in number of fins, the heat release performance of the extruded-type heat sink was lowered only 7% than that of the swaged-type. We believe that, this shows the increment of effective heat transfer area by the laterally waved surface of fins and the better heat transfer property of the extruded-type heat sink.}, journal = {International Journal of Industrial and Manufacturing Engineering}, volume = {6}, number = {12}, year = {2012}, pages = {2827 - 2830}, ee = {https://publications.waset.org/pdf/1848}, url = {https://publications.waset.org/vol/72}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 72, 2012}, }
