PROBLEM TO BE SOLVED: To provide a power generator using cold LNG that can be utilized in a satellite base in the hinterland where sea water cannot be used, while facilitating maintenance of the thermoelectric conversion elements.SOLUTION: A power generator 1 using cold LNG uses an air temperature type carburetor 4 as an LNG vaporizer, and since thermoelectric conversion elements 21 are attached to both front and rear surfaces of a fin 20 formed on the outer periphery of an evaporation tube 18 of the air temperature type carburetor 4, the power generator can be utilized in a satellite base in the hinterland where sea water cannot be used, and maintenance of the thermoelectric conversion elements 21 can be facilitated. Furthermore, the power generator 1 using cold LNG can raise the surface temperature of the thermoelectric conversion element 21 on the atmosphere side above the atmospheric temperature, by blowing the air warmed in a box-shaped package of a cogeneration system forcibly to the surface of the thermoelectric conversion element 21 by means of a blower, and can increase temperature difference between the low temperature side (surface side of the fin 20) and the high temperature side of the thermoelectric conversion element 21. |
