<p>PROBLEM TO BE SOLVED: To utilize cold heat of low-temperature fluid easily and wit high efficiency with thermoelectric conversion elements disposed at high density, by generating power with the condensation part of a heat pipe disposed in a low-temperature fluid passage, and disposing the vaporization part at a heater. SOLUTION: A cold heat power generation device is constituted by layering and disposing a number of flat heat pipes 31 formed by bonding a number of thermoelectric conversion element 33 to both surfaces of their vaporization parts. The vaporization part of the flat heat pipe 31 is disposed in a heating fluid passage, and its condensation part is disposed in a low-temperature fluid passage 36. At the outer surface of a portion 32 corresponding to the thermal insulation part of the flat heat pipe 31, crossing between the heating fluid passage 34 and the low-temperature fluid passage 36, if necessary, a thermal insulation material or the like is disposed, so as to thermally insulate. By using the flat heat pipe 31 for cold heat transmission, it is possible to dispose the thermoelectric conversion elements at high density, and generate power very effectively by utilizing the cold heat of low-temperature fluid, such as LNG, LPG, LN2 with high efficiency.</p> |
