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

Flow path structure of heat exchanger, and heat exchanger

A heat exchanger according to the present invention includes: a pillar shaped honeycomb structure having a plurality of cells, the cells providing first flow paths through which a first fluid is passed; an inner cylinder attached to an outer periphery of the honeycomb structure; and an outer cylinder disposed on an outer periphery of the inner cylinder, the outer cylinder providing a second flow path through which a second fluid is passed, the second flow path being arranged between the outer cylinder and the inner cylinder. The second flow path includes: an intermediate flow path extending in an axial direction of the honeycomb structure so as to include an outer peripheral position of the honeycomb structure; and side flow paths located on both sides of the intermediate flow path in the axial direction. The intermediate flow path has a height lower than that of each of the side flow paths.
