摘要:
A crosscurrent heat exchanger body made up of a stack of joined, parallel flow web plates (1), and a hollow chamber (5) for flow across them between each two successive web plates, with the cover layers (2,2') of successive web plates being sloped toward one another at their ends over the hollow chamber (5) enclosed between them, and being joined tightly to one another over the entire width, is disclosed.
摘要:
The invention concerns a method for the production of a flat composite (5) from plastic parts by means of a thermal adhesion of two plastic parts (1,1′), heated on one side of their surfaces (1a,1a′), consisting of plastics A and B, wherein the surfaces (1a,1a′) are heated on the adhesion side to surface temperatures of 10 to 100° K. above the Vicat softening points VET (according to DIN ISO 306) of the pertinent plastics A and B, provided that the plastic parts (1,1′) retain their original shape during the preheating phase, and are pressed between a pair of rolls (2,3), at an advance rate between 5 and 200 mm/sec and with a pressing force between 10 and 500 N acting on the roll (3); preferably, the plastics (1,1′) exhibit engraving or embossing (6,6′), with which composite (5) can be produced with a three-dimensional inclusion (7) of a defined shape; furthermore, a flat or elongated object (8) is embedded between the plastic parts (1,1′) to be adhered during the adhesion of the composite (5).
