Title:
TOTAL HEAT EXCHANGE ELEMENT AND VENTILATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/034640
Kind Code:
A1
Abstract:
This total heat exchange element is configured by partition plates (2), and space-holding members (3) processed into a corrugated shape with a plurality of pointed ends connected by side walls (32), being stacked in such a manner that the extension directions of the plurality of pointed ends of the adjacent space-holding members (3) intersect. This total heat exchange element has a plurality of flow paths (71x, 72x, 73x, 74x, 75x, 76x) between the two adjacent partition plates (2) in the stacking direction, which are surrounded by the partition plates (2) and the side walls (32). The plurality of flow paths (71x, 72x, 73x, 74x, 75x, 76x) include a flow path (71x, 74x) having line symmetry with respect to a straight line extending in the stacking direction, and a flow path (72x, 73x, 75x, 76x) having no line symmetry with respect to the straight line extending in the stacking direction. The length of the side walls (32) that define the flow path (72x, 73x, 75x, 76x) having no line symmetry is longer than the length of the side walls (32) that define the flow path (71x, 74x) having line symmetry.
