Abstract

The objective of this study is to investigate low temperature performance characteristics of the thermosyphon with/without wick. Thermosyphons using water as the working fluid are tested with variations of wick, charge amount of the working fluid, outdoor temperature, and heat load for the evaporator section at a low temperature. As a result, the heat transfer of thermosyphon was optimized at the charge amount of 40% and increased with the rise of the outdoor temperatures.

본 연구의 목적은 심지구조 유무에 따른 자동차에 적용된 써모사이폰의 저온 작동영역에서의 성능 특성을 고찰하는 것이다. 이를 위하여 작동유체로 물을 사용하는 써모사이폰을 제작하였고, 작동유체의 충진량, 심지 적용 유무, 외기온도 변화 그리고 증발부에 열부량 변화에 따른 성능 특성을 파악하였다, 결과적으로 작동유체의 충진량 40%에서 최적의 열전달 성능을 나타내고, 외기온도 증가에 따라 써모사이폰의 열전달 성능이 증가하였다.
