PROBLEM TO BE SOLVED: To provide a heat exchanger in which an outer pipe for a group of pipes and heat transfer pipes can be precisely assembled, the number of assembling processes of the outer pipe for a group of pipes and the heat transfer pipes upon their alignment, a manufacturing cost is lowered and a decentering is not generated by simplifying the alignment when the outer pipe for a group of pipes and the transfer pipes are assembled. SOLUTION: Heat transfer pipes are supported in a tubular outer pipe 1 for a group of pipes through pipe support plates 3. The outer pipe 1 for the group of pipes are housed in a main body 100 in a heat exchanger. The outer pipe 1 for the group of pipes are divided into a plurality of parts in the longitudinal direction of the main body 100 and the respective parts are fixed to the main body 100. The pipe support plates 3 are provided between the divided outer pipes 1 for the group of pipes. The pipe support plates 3 are attached to the main body by providing aligning members between their outer peripheries and the inner periphery of the main body 100 so that the number of aligning processes is decreased. |
