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.
