PROBLEM TO BE SOLVED: To provide a heat exchanger that promotes turbulence of a fluid flowing between an inner pipe and an outer pipe to improve heat exchange performance.SOLUTION: A heat exchanger includes an inner pipe 13 in which a first fluid flows and which comprises a plurality of pipes formed into a spiral shape, and an outer pipe 11 in which a second fluid flows. In the heat exchanger, the inner pipe 13 is arranged in the outer pipe 11, a plate-like member 18 through which the inner pipe 13 is passed is included, and a slewing part 19 is provided on the outer periphery of the plate-like member 18. Not only in the vicinity of the inner pipe formed into the spiral shape, but also in a place in which the gap between the inner pipe 13 and the outer pipe 11 becomes large, turbulence of the second fluid makes promoted, and heat transmission on the second fluid side can be improved. |
