WIPO Patent Application WO/2014/013725
Kind Code:
A1
Abstract:
Provided is heat exchanger in which a rib (25) of a core plate (20) has a shape that is depressed from a flat surface (211) of a flat surfaced main-body part (21), and the rib (25) is provided with: a rib bottom part (251) including a base (251a) that is depressed from and parallel to the flat surface (211) of the flat surfaced main-body part (21); and a rib incline part (252) that is positioned between the rib bottom part (251) and a flat part (26). The rib (25) is positioned so that the rib incline part (252) overlaps, in the tube stacking-direction (Y), the edge (10a) of the tube (10) in the width-direction (Z). Accordingly, even if the core plate width is small, the rib (25) will overlap the tip part of the tube (10) in the tube stacking-direction, and the rib (25), which is positioned so that the flat part (26) is present between the rib (25) and a groove part (22), can be formed by press molding.
