Title:
HEAT EXCHANGE ELEMENT, HEAT EXCHANGE VENTILATION DEVICE, AND METHOD FOR MANUFACTURING HEAT EXCHANGE ELEMENT
Document Type and Number:
WIPO Patent Application WO/2019/207733
Kind Code:
A1
Abstract:
A heat exchange element according to the present invention has a counterflow section provided with a plurality of partition plates exhibiting a flat shape and a plurality of spacer plates exhibiting a wavy shape in a cross-sectional view, the partition plates and spacer plates being stacked alternately such that the direction of advance of the wavy shape of the spacer plates is in the same direction. Side surfaces of the counterflow section are formed by bending the overlapped tip portions of the stacked partition plates and spacer plates. As a result of this configuration, in the heat exchange element according to the present invention the heat-insulating property between the flow paths of the heat exchange element and the outside air is higher, and the exchange of heat between a fluid inside the flow paths of the heat exchange element and the outside air can be reduced. Consequently, a heat exchange element having a higher heat exchange efficiency is obtained.
