Title:
HEAT EXCHANGE ELEMENT
Document Type and Number:
WIPO Patent Application WO/2021/156979
Kind Code:
A1
Abstract:
A heat exchange element (100) is formed by alternately stacking a first heat exchanger plate (1) and a second heat exchanger plate. The first heat exchanger plate (1) has: a first central portion (11) that forms a plurality of first partial channels (31) and a plurality of fourth partial channels (41); a first header portion (12) that forms a plurality of second partial channels (32); and a second header portion (13) that forms a plurality of third partial channels (33). The second heat exchanger plate has: a second central portion that forms a plurality of fourth partial channels (41) and a plurality of first partial channels (31); a third header portion that forms a fifth partial channel; and a fourth header portion that forms a sixth partial channel. The first central portion (11) has a first corrugated portion (14) of a corrugated shape and a first flat portion (15) of a flat shape. At least part of the first partial channels (31) and at least part of the fourth partial channels (41) are formed by the first corrugated portion (14) and the first flat portion (15).
