Title:
HEAT TRANSFER PIPE AND VAPORIZER
Document Type and Number:
Japanese Patent JP2017150726
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a heat transfer pipe capable of suppressing ice accretion at a connection part of fins, and a vaporizer with the same.SOLUTION: A heat transfer pipe 1 vaporizes a liquid medium such as LNG by performing heat exchange between the liquid medium and water for heating, such as sea water at temperature higher than that of the liquid medium. The heat transfer pipe 1 is provided with: a tubular body part 2 including a flow channel 7 through which the liquid medium passes; and a plurality of fins 3 projecting outward from an outer peripheral surface of the body part 2. The plurality of fins 3 are spaced apart from each other in a circumferential direction of the body part 2. When the maximum radius of the flow channel 7 is considered as r, and the minimum thickness required to withstand pressure in vaporization of the liquid medium at the body part 2 is considered as t, a connection part 6 connecting root parts of the adjacent fins 3 has a straight part 11 contacting a circular arc Chaving curvature of radius (r+t).SELECTED DRAWING: Figure 1
