Title:
INNER FIN
Document Type and Number:
WIPO Patent Application WO/2024/070441
Kind Code:
A1
Abstract:
This inner fin is configured from a plurality of protrusions that are continuous in the width direction, the plurality of protrusions extending in the flow-path direction. The protrusions have contact parts that contact one of two plate parts, the contact parts extending linearly along the flow-path direction. The protrusions have wave-form shapes that vary regularly in a period T along the flow-path direction as seen from the planar direction orthogonal to the flow-path direction and the width direction. The shape of a cross-section orthogonal to the flow-path direction in the protrusions has a first section that rises from the other of the two plate parts toward the one of the two plate parts and reaches the contact part, and a second section that falls from the contact part toward the other of the two plate parts. Within the cross-sectional shape of the protrusions in a reference cross-section and in a portion obtained by removing a cross-section at a site represented by period T/2 from the reference cross-section, the curvature at a site configured from a curve that reaches the contact part in the first section and the curvature at a site configured from a curve that extends from the contact part in the second section are different from one another.
