Heat treatment device

Abstract

A heat treatment device causing a first fluid and a second fluid to flow therethrough includes heat transfer bodies including first flow channels through which the first fluid flows and second flow channels through which the second fluid flows adjacent to the first flow channels without contact, and pipe-like members detachably placed in the first flow channels and each including a pipe wall having an outer wall surface conforming to a wall surface defining each first flow channel and an inner wall surface with which the first fluid comes into contact.

What is claimed is: 
     
         1 . A heat treatment device causing a first fluid and a second fluid to flow therethrough, the device comprising:
 a heat transfer body including a first flow channel through which the first fluid flows and a second flow channel through which the second fluid flows adjacent to the first flow channel without contact; and   a pipe-like member detachably placed in the first flow channel, and including a pipe wall having an outer wall surface conforming to a wall surface defining the first flow channel and an inner wall surface with which the first fluid comes into contact.   
     
     
         2 . The heat treatment device according to  claim 1 , wherein the pipe-like member includes a projection projecting to an outside of the outer wall surface of the pipe wall at an opening on one side of the pipe-like member. 
     
     
         3 . The heat treatment device according to  claim 2 , wherein the pipe-like member is provided with a seal member for sealing a gap between the projection and the heat transfer body when the pipe-like member is placed in the first flow channel. 
     
     
         4 . The heat treatment device according to  claim 2 , wherein the heat transfer body includes a groove for housing the projection when the pipe-like member is placed in the first flow channel.
