HEAT ENGINE, RADIATOR FOR HEAT ENGINE, AND MANUFACTURING METHOD OF RADIATOR FOR HEAT ENGINE

摘要

PROBLEM TO BE SOLVED: To provide a heat engine, a radiator for the heat engine, and a manufacturing method of the radiator for the heat engine, which abolish a water transfer means such as a transfer pump transferring a working fluid for cooling.;SOLUTION: The heat engine has: a compression part 1 compressing a working fluid; the radiator 2 radiating heat of the working fluid compressed by the compression part 1; a heat absorption part 6; and an expansion part 3 obtaining cooling power or power from the radiated working fluid. The radiator 2 has: a heat receiving part 20 receiving heat of the compressed working fluid; a housing part 22 having a vaporization chamber 21 housing a cooling fluid W and promoting vaporization of the cooling fluid W by heat transferred from the heat receiving part 20; a liquefaction part 23 cooling the cooling fluid W vaporized by the vaporization chamber 21 and liquefying the cooling fluid W; and a return passage 25 returning the cooling liquid W liquefied by the liquefaction part 23 to the vaporization chamber 21. It is preferable that the vaporization chamber 21 is decompressed more than the atmospheric pressure.;COPYRIGHT: (C)2008,JPO&INPIT
