Claims

[Scope of Claim for Utility Model Registration] 1. In an open rack type liquefied gas vaporizer in which a heat exchange panel is constructed by connecting finch tubes and a heat medium flows down from a water sprinkler disposed above the heat exchange panel, A turbulence promoter with a small frictional pressure loss is inserted into the lower liquid phase and evaporation region of the entire length of the fluid passage, and a turbulence promoter with a larger frictional pressure loss than the turbulence promoter is inserted into the remaining upper gas phase region fluid passage. An open rack type liquefied gas vaporizer characterized by inserting a turbulence promoter. 2. The open rack type liquefied gas vaporizer according to claim 1, which is characterized in that an orifice is provided at the fluid passage outlet of the finch tube to increase pressure loss.
