Title:
HEAT EXCHANGE ELEMENT AND HEAT EXCHANGE VENTILATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/053082
Kind Code:
A1
Abstract:
A heat exchange element (100) comprises first partition plates (1) and second partition plates (2) that are alternately layered. The first partition plates (1) and the second partition plates (2) respectively have counter flow parts (10, 20) that exchange heat between a fluid flowing through a plurality of first flow paths (3) and a fluid flowing through a plurality of second flow paths (4). The counter flow part (10) of each of the first partition plates (1) has a waveform shape in which a plurality of first flow path ribs (11) protruding from one surface in the layering direction are arranged in parallel. The counter flow part (20) of each of the second partition plates (2) has a waveform shape in which a plurality of second flow path ribs (21) protruding from one surface in the layering direction are arranged in parallel. The first flow path ribs (11) are longer in the layering direction as compared to the second flow path ribs (21). The counter flow part (20) of each of the second partition plates (2) is formed by a sheet material higher in moisture permeability than that of the counter flow part (10) of each of the first partition plates (1).
