Title:
HEAT EXCHANGE ELEMENT AND HEAT EXCHANGE TYPE VENTILATION DEVICE USING THE SAME
Document Type and Number:
Japanese Patent JP2019168148
Kind Code:
A
Abstract:
To solve the problem in which, by expansion/contraction of a flat plate, the height of an air passage changes, deviation occurs in the air flowing in a heat exchange element, and heat exchange efficiency deteriorates.SOLUTION: In a heat exchange element, a plurality of heat transfer plates are laminated with predetermined intervals, and in the plurality of intervals formed by the plurality of heat transfer plates, ventilation is performed in the intervals so that a supply airflow and an exhaust airflow are adjacent to each other alternately and perpendicular to each other, and heat is exchanged between the supply airflow and the exhaust airflow via the heat transfer plates. The intervals are formed by the ribs standing from the heat transfer plates, and air passages of the supply airflow and the exhaust airflow are formed in the intervals. The rib is constituted so that the heat transfer plate covers a rib reinforcing material. The rib reinforcing material is constituted by a material whose ratio of expansion and contraction according to temperature and humidity change is smaller than that of the heat transfer plate.SELECTED DRAWING: Figure 3
