PROBLEM TO BE SOLVED: To provide a heat pipe preventing damage of a pipe body due to freezing of a working liquid in a cold district, and providing almost the same operation performance as a heat pipe using water as the working liquid. SOLUTION: The heat pipe uses water containing 0.5-10wt.% of glycol as the working liquid. It is preferable that the glycol is ethylene glycol and/or propylene glycol, and the water is distilled water or deionized water. COPYRIGHT: (C)2005,JPO&NCIPI
