PROBLEM TO BE SOLVED: To provide a heat exchanging device 100 in which a high temperature structure 1 is arranged in a heat exchanger 75 and which has a heat insulating function capable of suppressing heat radiation from the inside high temperature structure 1 to the outside.SOLUTION: A heat device has a high temperature heat exchanging flowing channel 21 and a low temperature heat exchanging flowing channel 22 constituting heat exchanging flowing channels 21, 22 exchanging heat turning around a structure 1 in which a high temperature fluid and a low temperature fluid are adjacent to each other and which comprises a fuel cell 2 or others in a laminar state in a heat exchanger 75. The high temperature heat exchanging flow channel 21 turns the high temperature fluid discharged from the structure 1 and discharge it. The low temperature heat exchanging channel 22 turns the low temperature fluid from an outer peripheral side to an inner peripheral side and introduces it into the structure 1. The low temperature heat exchanging flowing channel 22 of the high temperature heat exchanging flowing channel 21 and the low temperature heat exchanging flowing channel 22 turns around the outermost periphery of the heat exchanging flowing channels are. The structure 1 is arranged so as to be surrounded by the heat exchanging flowing channels 21, 22 by the turning of the heat exchanging flowing channels 21, 22. |
