전자교환시스템 냉각을 위한 히트파이프 적용 연구 = A study on the application of heat pipe to the cooling of ATM switching system

다국어 초록 (Multilingual Abstract)

In the present study, the cooling package using the heat pipe has been developed to improve the thermal performance in the point of cooling characteristics of the electronic chip placed to the subrack being readily assembled and disassembled in ATM switching system. As the preliminary experiments, the cooling performances between a conventional way using a cooling fin and a proposed method applying the heat pipe are compared and analyzed. The cooling performance at a simulated electronic component packaging a heat pipe module is approximately achieved up to $5.0W/cm^2$ heat flux and the allowable temperature at the heated chip is sustained in the range within $70^{\circ}C$. From the results, it is confirmed that temperature oscillations are also settled by inserted wick in the evaporator section. From the user's viewpoint, the method to assemble and disassemble the heat pipe easily has been devised.
