Abstract
A heat exchangerincludes: an inner cylinderthrough which a first fluid can flow, the inner cylinderbeing configured to be capable of housing a heat recovery member; an outer cylinderdisposed so as to be spaced on a radially outer side of the inner cylindersuch that a second fluid can flow between the outer cylinderand the inner cylinder; and an intermediate cylinderdisposed between the inner cylinderand the outer cylinder, the intermediate cylinderpartitioning a flow path for the second fluid into an inner flow pathand an outer flow path. In the heat exchanger, the intermediate cylinderincludes communication holesthat are communicated in a radial direction, and the communication holesare provided in an axial direction of the intermediate cylinder
