통신장비용 공냉형 냉각시스템의 성능 특성에 대한 실험적 연구

The objective of this study is to analyze the cooling performance of an air-cooling system for telecommunication equipment. Temperature variation and capacity were measured in an actual unit for telecommunication equipment. In addition, the cooling performance was measured by installing a silicon rubber heater as a heat source in a cabinet. The standard thermal load for telecommunication equipment was approximately 293 W, and the maximum temperature of the heated surface was 64.5℃. The average and maximum temperatures of the heated surface were proportional to the inlet air temperature. When the heat load increased from 293 W to 400 W, the maximum temperature of the heated surface was higher than 64.5℃ even though the inlet air temperature decreased from 25 to 11℃.
