摘要： An annular-shaped heat exchanger 2 provided with a high-temperature fluid passage inlet 11 at one end in the axial direction and a low-temperature fluid passage inlet 15 at the other end in the axial direction is supported inside a cylindrical outer casing 9 via a heat exchanger supporting ring 36. The heat exchanger supporting ring 36 connecting a low-temperature section near the low temperature fluid passage inlet 15 of the heat exchanger 2 and a rear flange 33 of the outer casing 9 is formed by bending a plate member in a cross-sectionally step shape so that it can readily undergo elastic deformation to offset the thermal expansion of the heat exchanger 2. This ensures positive sealing between the high-temperature fluid passage inlet 11 and the low-temperature fluid passage inlet 15 of the heat exchanger 2 while minimizing the thermal stress occurring in the heat exchanger 2 and the outer casing 9. The heat exchanger supporting ring 36 also has a function of partitioning between a combustion gas passage inlet 11 and an air passage inlet 15.

摘要： First heat transfer plates S1 and second heat transfer plates S2 folded along crest folding lines L1 and valley folding lines L2 are bonded to an inner periphery of an outer casing 6 and an outer periphery of an inner casing 7, so that the first and second heat transfer plates S1 and S2 are disposed radiately, thereby forming combustion gas passages and air passages circumferentially alternately. One end of both the combustion gas passages and the air passages is cut into an angle shape, and one side and the other side of the angle shape are closed to form combustion gas passage inlets 11 and air passage outlets 16. In a similar manner, combustion gas passage outlets 12 and air passage inlets 15 are formed at the other end of the combustion gas passages and the air passages. Thus, it is possible to provide a heat exchanger which has a simple structure and is easy to manufacture, and in which the pressure loss due to bending of flow paths can be suppressed to the minimum.
