PROBLEM TO BE SOLVED: To provide a loop type heat pipe with reduced heat resistance between a surface of an evaporation part and liquid-phase working fluid by increasing a contact area of the surface of the evaporation part and the working fluid.SOLUTION: In a loop type heat pipe 10, an evaporation part 11 removing heat from a heating element 8, and a condensation part 12 radiating heat to the outside are communicated with each other, so that a circulation path is formed by an evaporation pipe 13 and a liquid return pipe 14, and fluid with a condensation property is sealed as working fluid while inside of the circulation path is deaerated. The condensation part 12 is arranged at a position higher than the evaporation part 11 so as to radiate heat to the outside. The loop type heat pipe comprises liquid injection means 16, 17, 18, 22, 26 for making the working fluid into fine droplets and supplying it to the evaporation part 11 at high pressure. |
