摘要： PROBLEM TO BE SOLVED: To provide an LPG vaporizing mechanism capable of developing a high evaporating efficiency despite the fact that the mechanism is an evaporator of atmospheric heat absorbing type requiring no heat source. SOLUTION: Liquefied LPG is led from a liquid phase 11 in a container or a storage reservoir 10 to a double fin tube 14 through a tube 12 and a hydraulic pressure regulating valve 13. The pressure of the liquefied LPG is regulated by the hydraulic pressure regulating valve 13, for example, to 0.1 MPa (temperature of LPG -25 deg.C). On the other hand, vaporized gaseous LPG is led from a gas phase 15 in the container or the storage reservoir 10 to the tip part of the inner tube 18 of the double fin tube 14 through a tube 16 and a pressure reducing valve 17, and discharged from a small hole 19 at the bottom of the inner tube 18 into the liquefied LPG. The liquefied LPG receives an atmospheric heat absorbed from fins 21 and a heat quantity of the gaseous LPG while the LPG passes a clearance between the outer tube 20 and the inner tube 18 of the double fin tube 14 to increase the temperature so as to promote the evaporation. The pressure of the gaseous LPG led into the inner tube 18 is set higher than that of the liquefied LPG, i.e., set higher than 0.1 MPa.
