PURPOSE: To ensure disassembling of a heat exchanger and exchange of members, by coupling two parallely disposed host pipes through a bundle shaped molded small pipe, and holding a plurality of host pipe divisions with an internal tension resistant bar. CONSTITUTION: Host pipes 2, 3 of a heat exchanger 1 are formed from a plurality of host pipe divisions 5, 6 and are coupled through many molded small pipes 21. Tensile resistant bars 7, 8 are disposed in the host pipe divisions 5 in opposition to a pipe wall 22, are extended along an inner wall of the host pipe, and are finally fixed to host pipe end divisions 11 through a fixed flange 4 and a thread hole 23. Guide shoulders 24, 25 prevent sliding of the other end of the tensile resistant bars 7, 8 or mutual rotation of the host pipe divisions. The tensile resistant bars 7, 8 include a heat insulation layer 10 and a shielding thin plate 28 for shielding from an inner chamber 9 in the host pipe divisions 5. |
