HEAT EXCHANGER

PURPOSE:To enhance assembling workability and embody the cost reduction by engaging a heat exchanger element laminated body having elasticity in their lamination direction with a stopper installed to an end plate laid out on both ends and holding an engaged stopper of a column-shaped frame body in an assembled state. CONSTITUTION:A plurality of elastic plastic-made straws 3 are pasted on a rectangular-shaped heat exchanger sheet 2 as a segment member, thereby constituting heat exchanger elements 4. A larger number of the heat exchanger elements 4 thus constituted are stacked in such a manner that the direction of each adjacent member may be changed by 90 degrees, thereby constituting elastic element laminated bodies 1 in the lamination direction. A end plate 6 which forms a fine groove 8 as a stopper at each dihedral angle on the outer surface, is laid on both ends of the element laminated bodies 1 while a holding frame 5 is mounted so that both end plates 6 may be coupled with a column- shaped frame member 7, thereby assembling a heat exchanger. The column- shaped frame body 7 has engagement pieces 9 on both ends to which a claw 9a is installed to fit into the fine groove 8. The claw 9a engaged with the fine groove 8 holds the element laminated bodies 1.
