自動車の排熱利用を目指した kW 級ループヒートパイプの構築と過渡的熱流動特性の評価

抄録

This paper reports the test results of a newly developed kW-class loop heat pipe (LHP), which is passive heat transfer device, for effective heat utilization of automobile. The LHP has 2 μm wick made of stainless steel. Pure water was used as a working fluid. The LHP was designed, fabricated, and tested under atmospheric condition. The LHP could transport heat up to 1.9 kW. A transient thermal analysis model based on a mass-spring-dumper system was also developed and compared with the test results. The analytical result relatively agreed well with the test result.
