1. method for the manufacture of the many openings that comprise a plurality of retes, adverse current plate heat exchanger, described method comprises the following steps:

  • (a) by the first tabs is orientated as the first rete and is formed plate heat exchanger by the wall scroll continuous film band with the first edge and second edge;

    (b) described film band is carried out 180 ° and

    turn to first to be folded to form the second tabs that covers described the first tabs, described the second tabs comprises the second rete;

    (c) by beginning that from described the first burst the first side edge of described the first and second tabs is engaged the first manifold portion that then stops forming a plurality of the first manifold portion discontinuously, thereby form a plurality of the first film sealings, and by then stopping forming the first other manifold portion along described the first edge at the unsealing section joint that begins apart from previous described the first manifold portion one segment distance place described the first edge, thereby form a plurality of the first other film sealings, described the first manifold portion is limited by described the first film sealing;

    (d) by beginning the Second Edge edge of described the first and second tabs is engaged initial the second manifold portion that then stops forming in a plurality of the second manifold portion discontinuously apart from described the first burst one segment distance place, thereby form a plurality of the second film sealings, and by beginning then unsealing the second edge join is stopped forming the second other manifold portion along described the second edge apart from previous described the second manifold portion one segment distance place, thereby form other the second film sealing, described the second manifold portion is limited by described the second film sealing;

    (e) in described continuous film band, carry out 180 °

    turn to second be folded to form the 3rd tabs that covers described the second tabs, described the 3rd tabs comprises the tertiary membrane layer;

    (f) join the first edge of adjacent described the 3rd tabs to form a plurality of the 3rd manifold portion along described the first edge by unencapsulated the first edge with described the second tabs, thereby form a plurality of tertiary membrane sealings, described the 3rd manifold portion is limited by described tertiary membrane sealing;

    (g) join the second edge of adjacent described the 3rd tabs to form a plurality of the 4th manifold portion along described the second edge by unencapsulated the second edge with described the second tabs, thereby form a plurality of the 4th film sealings, described the 4th manifold portion is limited by described the 4th film sealing;

    (h) repeating step (e), (f), (g) form the continuous pleating membrane exchanger with stacked array path between described rete thus.
