じる平面内応力である。When the above-mentioned conventional plate-fin type heat exchanger is used for heat exchange of a high-temperature fluid having a small flow rate and a small temperature change, the temperature in a plane based on the flow path shape of the fin plate 3 is increased. The main problem is thermal stress due to distribution and high temperature creep caused by the thermal stress. In this case, the steep slope of the steady temperature distribution due to the flow path arrangement of the heat transfer section, heat transfer performance, the position of the inlet / outlet header of the fluid, etc. , It is important to eliminate high temperature parts,
Although a temperature gradient may occur to the side plates 8 due to heat loss, most of the problems are in-plane stresses simultaneously generated in each stage of the fin plate 3.

コア部７に応力が集中するという問題があった。[0005] However, the conventional plate fin type heat exchanger has a problem to reduce the generation of in-plane thermal stress as described above, whereas the plate fin used for recovering exhaust heat of high-temperature exhaust gas from a gas turbine or the like, for example. In the type heat exchanger, the flow rate, the temperature, and the like change remarkably between several seconds and several tens of seconds when the load of the gas turbine changes greatly or at the time of emergency stop. At this time, the heat exchange between the high-temperature fluid having a small flow rate and a small temperature change is caused by the difference in the thermal responsiveness of the fin plate 3, the separator 6, and the side plate 8 that transfers the heat exchange between the heated fluid 1 and the heating fluid 4. In this case, a temperature distribution in the stacking direction, which did not occur, occurs. In particular, the side plate 8 integrally attached so as to sandwich the core portion 7 is formed as thick as several millimeters for the purpose of pressure resistance, high temperature resistance, or for the purpose of configuration such as connection with piping.
The fin plate 3 and the isolation plate 6 are formed of thin members of 1 mm or less in consideration of heat transfer performance. The plate 6 immediately follows the temperature change, and the response of the side plate 8 which is thick and has a large heat capacity is delayed even if there is a temperature change. As a result, a sharp temperature gradient occurs in the laminating direction as shown in FIG. There is a problem that stress concentrates on the core portion 7 near the position 8.

It is an object to provide a heat exchanger.
