PURPOSE:To realize the extremely high total heat exchanging efficiency by a method wherein plural concave-convex parts are provided on the surface of a main plate of a total heat exchanger having a blowing function, a total heat exchanging area included between air flows on both surfaces of the main plate is extremely increased, and the growth of temperature and humidity boundary layer is prevented by the concave-convex parts. CONSTITUTION:A disc-shaped main plate 8 made of Ni porous material having 1mm. thickness finished by drying after impregnated with LiCl on the surface thereof is mounted on a rotating shaft 9. Plural blades 10 at the A air flow side and plural blades 11 at the B air flow side are joined on the both sides of the main plate 8. The blades 10 at the A air flow side are provided with a side plate 12 and a sucking port 13, the blades 11 at the B air flow side are provided with a side plate 14 and a sucking port 15, an impeller 16 is integrally composed of those members and fixed to the rotating shaft 9. Plural concave-convex parts 20 is provided on the surface of the main plate 8. The concave-convex parts 20 is formed in a long radial manner extended from the rotating center of the main plate 8. |
