De-icing apparatus for vaporizer with enclosed walls

摘要

PURPOSE: A closed type anti-freezing device for a vaporizer is provided to prevent the lower part of a vaporizer from being frozen by heating the vaporizer with solar radiation energy in a state where the vaporizer is separated from atmosphere by a closed body having a transparent window. CONSTITUTION: A closed type anti-freezing device(100) for a vaporizer comprise a vaporizer(200) and a closed body(300). The vaporizer changes liquefied gas to evaporative gas by heat-exchanging the intake liquefied gas with atmosphere, and discharges. The vaporizer comprises a heat exchanger(230). In the heat exchanger, a liquefied gas intake pipe and an evaporative gas discharge pipe are respectively used as an inlet and an outlet. The closed body surrounds the vaporizer to be sealed, thereby blocking from external air.
