PROBLEM TO BE SOLVED: To easily assemble a heat exchanger with a small number of processes simply by preparing a specific number of closed type heat exchangers that have been manufactured in advance and inserting them between a pair of side plates for assembly. SOLUTION: An electrically insulated support member 14 for U vent pipes where recesses 15 for gripping the outside of a flex section 12a consisting of the U vent pipes 12 in each closed type heat exchanger B are formed with an interval is provided in multiple stages above and below the inner surface of a pair of support side plates 13. Then, the outside of each flex section 12a in the closed type heat exchanger B is inserted into the recesses 14 from the inside. In this state, the pair of support side plates 13 is retained by a tension member with an interval in a vertical posture, and the plurality of closed type heat exchangers B are supported between the support side plates 13, thus assembling a heat exchanger T where an air passage is formed among all pipes 11 of the adjacent closed type heat exchangers B in multiple, upper and lower stages. |
