DFSS 기법을 이용한 글로우 플러그 컨트롤러 Heat Sink 설계

Controller of Glow plugs with Diesel Engine have been designed for focusing on improvement of cold starting and following emission standard after starting up the engine on the diesel engine vehicle. However, recently around the world, according as reinforced regulation of low emission, the Glow plugs with Controller , Pre glowing time has been controlled instantly for more less White Smoke, NOx, Soot and so on. Therefore, it is expected more advantages, on the other hands, Glow plug heating must be controller to instant time with duty control methods, semiconductor switching device must be needed, but it has more temperature rising for switching loss. On this research, we present result that it minimizes the heat sink capacity related to switching emperature spreading with optimization of Heat Sink Capacity. The research has an optimum design of heat sink dimension with DFSS technique.
