PROBLEM TO BE SOLVED: To provide a heat exchange element capable of unvariably providing high heat exchange efficiency performance. SOLUTION: This heat exchange element 1 has an opposed part 5 of opposing an supply air duct 3 ventilating supply air A and an exhaust air duct 4 ventilating exhaust air B via heat transfer paper 2, for exchanging heat by ventilating the supply air A and the exhaust air B every one stage of a ventilation passage formed between a plurality of heat transfer paper 2 laminated at a predetermined interval, and an orthogonal part 6 orthogonally arranging the supply air duct 3 ventilating the supply air A and the exhaust air duct 4 ventilating the exhaust air B via the heat transfer paper 2, and also has a shielding rib 9 preventing leakage of an air current from a part except for an inflow port 7 and an outflow port 8 of the supply air A and the exhaust air B. The heat exchange element can be provided for eliminating a variation in the heat exchange efficiency performance even when deformation of the heat transfer paper is caused by influence such as humidity, by arranging the heat transfer paper 2 so that the hoop direction C of the heat transfer paper 2 becomes perpendicular to the flowing direction for ventilating the supply air A and the exhaust air B of the opposed part 5.

摘要:
A heat-transfer panel or sheet material comprises a woven wire mesh core of high thermal conductivity metal, for example copper or nickel, embedded in a closure layer of plastics material, for example a urethane, so that the mesh and the closure layer extend in the same longitudinal direction. The mesh core defines a nodal network and the nodes are located at or closely adjacent the outer surfaces of the closure layer so that satisfactory heat transfer between opposite sides of the panel is achieved over the whole outer surface area of the panel by virtue of heat conduction by the mesh core.

PURPOSE:To contrive to improve the performance of the sensible heat exchanger by a structure wherein hygroscopic and moisture permeable material is alternately employed in corrugated distance plates and plane partition plates so as to transfer moisture between flow passages in the heat exchanger, which exchanges only sensible heat between air flows with different temperature and humidity. CONSTITUTION:A first laminated sheet 30 is formed by laminating the two plane partition plates 21 and 22 to the distance plate 11 formed in corrugated manner. The distance plate 11 and the partition plate 21 contacting thereto are formed of material with hygroscopicity and moisture permeability, while the partition plate 22 is formed of material without hygroscopicity and moisture permeability. Furthermore, a second laminated sheet 31 is laminated to the first laminated sheet 30. In this case, the corrugated distance plate 12 and the plane partition plate 23 contacting thereto are formed of material with hygroscopicity and moisture permeability, while the partition plate 23 is formed of material without hygroscopicity and moisture permeability. A heat exchanger main body 10 is composed of the laminated sheets 30 and 31 alternately laminated to each other as mentioned above. Accordingly, fluid in cooling side passing within the first laminated sheet 30 is latent-heat-exchanged with fluid in the side to be cooled, which passes within the second laminated sheet 31, while accomplishing cooling action by vaporization.
