<P>PROBLEM TO BE SOLVED: To provide a countercurrent total heat exchanger that is reduced in adhered portion and enlarged in effective heat transfer area, thus resulting in high heat exchanging efficiency in principal. <P>SOLUTION: In the countercurrent total heat exchanger, a plurality of heat exchange members 20 each composed of a partition film 1 and a channel forming member 2 adhered to the partition film 1 to form a channel 7 are laminated up and down to perform heat exchange between the sensible heat and the latent heat of two types of gases via the partition films 1. The channel forming member 2 includes: a plurality of frame members 3 located along an outer edge 1a of the partition film 1; and a thin rib material 4 located between the two frame members 3 at predetermined spaces and having a width smaller than that of the frame member 3. The channel forming member further includes a strip-shaped cardboard member 9A for preventing shape changes of an inlet 5 and an outlet 6 in the inlet 5 and the outlet 6 of the channel 7. <P>COPYRIGHT: (C)2012,JPO&INPIT |
