Abstract

Official abstract text for this publication.

This heat exchanger includes a core and a header tank. The entire peripheral edge of an opening of the header tank welded to the core has a bevel inclined from the internal surface of the header tank toward the external surface thereof at a predetermined bevel angle. At least a portion of the peripheral edge of the opening of the header tank has a second inclined portion inclined from the external surface of the header tank toward the internal surface thereof at an angle larger than the predetermined bevel angle.

First claim

Opening claim text (preview).

The invention claimed is: 1. A heat exchanger, comprising: a core; and a header tank having an opening, an entire peripheral edge of the opening being welded to the core, wherein the entire peripheral edge of the opening of the header tank has a bevel inclined from an internal surface of the header tank toward an external surface thereof at a predetermined bevel angle, and at least a portion of the peripheral edge of the opening of the header tank has a second inclined portion inclined from the external surface of the header tank toward the internal surface thereof at an angle larger than the predetermined bevel angle such that a thickness of the header tank is reduced to a predetermined thickness, and only the bevel is welded. 2. The heat exchanger of claim 1 , wherein the core is a plate-fin core formed by stacking a plurality of plates on each other and brazing the plates together. 3. The heat exchanger of claim 1 , wherein the second inclined portion is provided in the entire peripheral edge of the opening of the header tank. 4. The heat exchanger of claim 2 , wherein the second inclined portion is provided in the entire peripheral edge of the opening of the header tank.
