: It was composed of: In order to assemble the meandering heat exchanger tubes 6 into the support plate 15, the straight tubes 6a constituting the meandering heat exchanger tubes 6 are penetrated into the through holes 16 of the support plate 15 one by one, and then the ends of the straight tubes 6a are attached to U3- It was assembled by sequentially connecting the vent pipes 6b and welding the joints.

かった。However, in the conventional exhaust heat recovery heat exchanger assembled as described above, a plurality of through holes 16 are bored in the support plate 15 constituting the support lattice frame unit. If the shortest distance between the edges of the pair of through holes 16 and 16 (hereinafter referred to as ligament length) is set below a certain limit, the strength of the support lattice frame unit will decrease, so the thickness of the support plate 15 is increased to ensure strength. This not only increases the weight of the support lattice frame unit, but also makes it difficult to drill holes with high precision. Furthermore, when inserting the straight pipe 6a of the meandering heat exchanger tube 6 through the support plate 15, the meandering heat exchanger tube 6 bends due to its own weight and comes into strong contact with the hole wall of the through hole 16, resulting in increased resistance and a long insertion process. In addition, the contact during insertion causes scratches and constrictions on the surface of the straight tube 6a, causing damage to the meandering heat exchanger tube 6. In addition, a large number of support plates 1

Therefore, it was difficult to insert the straight tube 6a of the meandering heat exchanger tube.

The work was difficult. In addition, if a welding defect in the U-vent @ 6b is discovered through a water pressure test, the U-vent pipe 6b must be cut and the straight pipe 6a must be handled, resulting in a number of problems such as troublesome work. there were.
