Document Type and Number:
WIPO Patent Application WO/2020/026921
Kind Code:
A1
Abstract:
A heat transfer member is provided with a group of heat transfer promoting portions (2) including a set of upstream side edge portions (20), a set of downstream side edge portions (21), and a recessed portion (22), provided on a fluid contacting surface (11). Adjacent sets of the upstream side edge portions protrude out from the contacting surface, each form an acute angle relative to the main direction of flow of the fluid, and extend in such a way as to approach one another with increasing distance toward the upstream side. Adjacent sets of the downstream side edge portions protrude out on the downstream side, to a greater extent than the upstream side edge portions, each form an acute angle relative to the main direction of flow, and extend in such a way as to approach one another with increasing distance toward the downstream side. The recessed portions are recessed to a greater extent than the upstream side edge portions and the downstream side edge portions, inside the sets of upstream side edge portions and the sets of downstream side edge portions. A plurality of the groups of heat transfer promoting portions are provided consecutively in the downstream direction. The downstream side edge portions of the upstream side heat transfer promoting portions are integral with the upstream side edge portions of the downstream side heat transfer promoting portions.
