This invention is structured by:
forming a core body 5 by turning-up a strip-shaped metal plate in fanfold manner to create a large number of flat flow passages; blocking the individual flow passages at both ends thereof using the respective comb teeth of a pair of comb-state members 6; and fitting the casing 9 to the core body 5, while providing inlet/outlet port of the fluid at a side face of the casing. The object of the invention is to establish uniform communication of thefluidinindividual flat flow passages. As a means for achieving the object, a pair of header portions 31 are provided at both end portions of the cylindrical casing 9, the inlet/outlet ports 11 are provided at both edge portions of one side of the casing 9 via a pair of small tank portions 28, the small tank portion 28 at inlet side of the first fluid 10 has a buffer plate 30 arranged at a position closer to the outlet side of the first fluid 10 between the core body 5 and the inlet/outlet port 11, thereby allowing the first fluid 10 to bypass the buffer plate 30 in the small tank portion 28 and to enter an end portion of the first flow passage 3 from an edge opposite to the outlet. |
