HEAT EXCHANGING DEVICE

PROBLEM TO BE SOLVED: To provide a heat exchanging device capable of securing sealing performance of high-temperature fluid while reducing thermal stress added to a core as a heat exchanger in recovering heat energy from the high-temperature fluid, and being constituted with an inexpensive material, and composed of the core and a duct for high-temperature fluid. SOLUTION: A high-temperature fluid inlet 3a of the core 2 and an outlet 10a of the duct 10 for high-temperature fluid are opposed to each other, the core 2 and the duct 10 are supported by an outer wall 11 surrounding them and a heat insulating material 20 disposed in a clearance between the outer wall 11, and the core 2 and the duct 10, and the circulation of the high-temperature fluid H from the outlet 10a of the duct 10 and the high-temperature fluid inlet 3a of the core 2 can be secured.
