る。Is this an example? As is clear from the above description, the heat exchanger of the present invention is constructed by laminating a plurality of unit members each having a plurality of rows of ribs on one side of a heat-conducting and moisture-permeable plate, thereby reducing the gap between each plate. νThis is a supply/receiver configured with multiple stages of back-row parallel flow paths formed by ribs, and the contact surface between two of the ribs on each unit member at both ends and one ribbed plate at the center is It has a rectangular rod shape that is wider than many other ribs, and the other ribs are configured in the shape of a single vibrator or round rod to increase the ventilation resistance in these parallel flow paths. Because of this, it is easy to layer unit members with each other, and the adhesion is good.The fitting of the plates and ribs during stacking is good because the contact surfaces of the ribs at both ends and the center are wide, and there are parallel flow paths with many other ribs. Since the ventilation resistance can be easily increased, the humidity exchange efficiency can be easily improved.
