落ちるという欠点がある。2. Description of the Related Art Conventionally, a large number of gas-gas heat exchangers have been used industrially for the purpose of recovering heat of exhaust gas. For example, insert a large number of heat transfer tubes into the cylindrical body,
A multi-tubular cylindrical heat exchanger is known in which heat is exchanged between a heat transfer tube inner fluid and a body fluid. In such a heat exchanger, a large number of manufacturing steps are required because many heat transfer tubes are inserted into the main body. In particular, in order to reduce the size, it is necessary to use a large number of thin heat transfer tubes, the man-hours must be increased, and the processing accuracy must be increased. Further, there is a drawback that it is difficult to clean the outside of the heat transfer tube. The spiral plate type heat exchanger is a heat exchanger configured by a spacer formed by welding two parallel flat plates to a plate, spirally wound so as to maintain a uniform interval, and both ends thereof being sealed. As a method of sealing both ends, there are a method of sealing both ends by welding and a method of sealing both ends with packing. If both ends are sealed by welding, they cannot be cleaned directly. Further, when used for applications where the temperature fluctuates periodically, in the case of a packing seal, the packing may break due to the expansion and contraction of the spiral plate, and extra bypass may increase or erosion may occur in the cover. There is also a plate fin type heat exchanger in which corrugated fins are sandwiched between flat plates and a large number of layers with both ends sealed by side bars are stacked. In order to assemble to such a structure, the brazing material is clad on both sides of the flat plate, and the flat plate, the corrugated fins, and the side bar are brazed together,
A leak-free pipeline must be created. Therefore, the structure is complicated, and a high degree of brazing technique is required.
Further, there is a cross flow type heat exchanger in which a large number of flat heat transfer plates are stacked, spacers are provided between the heat transfer plates so as to be orthogonal to each other, and the ends of the heat transfer plates are sealed. In such a heat exchanger, it is unavoidable that leakage occurs at the end seals and spacers. Further, since heat is exchanged by a cross flow, there is a drawback that thermal efficiency is lowered.

FIG. 1 shows a basic corrugated heat transfer plate. FIG. 2 shows that the corrugated heat transfer plate shown in FIG. 1 is sealed at both ends and a fluid inlet / outlet port is added. As shown in the figure, the hot fluid and the cold fluid are separated by the corrugated heat transfer plate 1. The high temperature fluid flows in through the high temperature fluid inlet 4 and is discharged through the high temperature fluid outlet 5, and the low temperature fluid flows in through the low temperature fluid inlet 2 and is discharged through the low temperature fluid outlet 3. During that time, heat is exchanged through the heat transfer plate 1. In FIG. 3, only one flow path of the corrugated heat transfer plate is sealed, and fluid inlets and outlets are provided at both ends of the heat transfer plate.
