  • Patent number: 7416018
    Abstract: The present invention relates to arrangement for a plate heat exchanger for connection to a system, of which the plate heat exchanger is designed to form part. The plate heat exchanger is of conventional construction with plates (2) parallel to one another, which constitute a package (1) and between them define flow channels. The outermost plates (2a, 2b) of the package (1) are at each short end partially covered by plate elements (6a, 6b), which essentially lie within the width of the package (1), of which the plate element (6a) situated nearest the system has throughholes (7) for assembly elements, which can be inserted into the holes (7) from above, since he pates (2) are formed with recesses (8). At each short end there are also clamping elements which effectively act between the plate elements (6a, 6b) and are designed to produce a symmetrical clamping force and to hold the package (1) together.
