Title:
VAPORIZER
Document Type and Number:
Japanese Patent JP2019027619
Kind Code:
A
Abstract:
To provide a vaporizer capable of letting two fluids, flowing inside and outside a heat transfer tube constituting a multi-tube heat exchanger, not come into contact with each other even if the heat transfer tube has a pinhole, a crack, etc., generated.SOLUTION: A vaporizer 1 comprises a multi-tube heat exchanger 18 constituted by arraying many heat transfer tubes 20, and is configured to exchange heat between two fluids differing in temperature through the heat transfer tubes 20 by letting one fluid flow inside the heat transfer tubes 20 and the other fluid flow outside the heat transfer tubes 20. The heat transfer tube 20 has a double-tube structure consisting of an inner tube 21 inside which the one fluid flows and an outer tube 22 outside which the other fluid flows, and is provided with a gap 23 between the inner tube 21 and outer tube 22.SELECTED DRAWING: Figure 1
