Abstract: A heat exchanger includes a plurality of fins that are spaced from each other and are arranged to divide a heat medium flow passage into a plurality of narrow passages. Each fin incudes a plurality of thick wall portions and a plurality of thin wall portions which are alternately arranged in a passage longitudinal direction. Each adjacent two of the plurality of fins, which are adjacent to each other, are defined as one fine and another fin, and each of the plurality of thick wall portions of the one fin is opposed to an adjacent one of the plurality of thin wall portions of the another fin in a fin arrangement direction, and each of the plurality of thin wall portions of the one fin is opposed to an adjacent one of the plurality of thick wall portions of the another fin in the fin arrangement direction.

Abstract: A flow path tube of a heat exchanger includes an inner fin having a meander shape in which a one-side top part and an other-side top part are alternately arranged via an intermediate part. The intermediate part includes a communication part with a communication port that communicates the adjacent fine flow paths. A one-side wall part is extended from the one-side top part, which is adjacent on one side, to the communication part and separates the adjacent fine flow paths. An other-side wall part is extended from the other-side top part, which is adjacent on the other side, to the communication part and separates the adjacent fine flow paths. An edge of the one-side wall part is formed such that an edge of the other-side wall part is shifted in parallel in the longitudinal direction of the flat cross sectional shape of the flow path tube.
