PCT No. PCT/SE93/00093 Sec. 371 Date Jul. 22, 1994 Sec. 102(e) Date Jul. 22, 1994 PCT Filed Feb. 5, 1993 PCT Pub. No. WO93/16346 PCT Pub. Date Aug. 19, 1993.A heat exchanger having plastic channel plates (10) is manufactured by stacking the plates with intermediate spacer members. The channel plates comprise two outer walls (12, 14) which are interconnected by a plurality of intermediate walls (16). The end-portions of the intermediate walls are melted along a predetermined length thereof, while the end-portions of the outer walls of each channel plate are caused to bend away from one another, such that the edges will form integrated unities with the edges of adjacent end-portions of adjacent channel plates. Prior to solidification of the resultant joins, the joins may be flattened-out with the aid of a roller. According to the invention, the spaces defined by the outer walls of the channel plates and the spacer members may be filled with plastic particles, which form an integrated unity with the end-portions of the channel plates. |
