  • Patent number: 7669646
    Abstract: A plate heat exchanger includes a heat exchanger block having a plurality of heat exchange passages. On the heat exchanger block, a header is mounted that extends over at least one part of one side of the heat exchanger block and establishes a flow connection between the heat exchange passages. The plate heat exchanger is provided with a fluid connection, which is formed by the header-side end of a pipeline. The fluid connection is essentially perpendicular to the side of the heat exchanger block over which the header extends. Within the pipeline directly in front of the header, there is a flow guide.

  • Publication number: 20070137844
    Abstract: In a plate heat exchanger having a heat exchanger block (1) with a number of heat exchange passages and a header (2) attached to the heat exchanger block, the header providing a flow connection between a portion of the heat exchange passages and a fluid connection (3), the header is defined by a cylinder jacket segment-shaped wall (7) and by a flat surface (12), which runs parallel to the axis of the cylinder (13) on a side (5) of the heat exchanger block. The length of the header extends over at least one portion of a side (5) of the heat exchanger block. At least one wall (7) of the header is connected to the side (5) of the heat exchanger block. The header is designed so that the axis (13) of the cylinder runs inside the header spaced at a distance (11) from the flat surface (12).

  • Patent number: 7100280
    Abstract: The invention relates to a method for producing a plate heat exchanger from a plurality of heat exchanger blocks (1a, 1b). Each heat exchanger block (1a, 1b) has mounted on it a header (6a, 7a, 6b, 7b) which extends over at least part of one side of the heat exchanger block (1a, 1b). The heat exchanger blocks (1a, 1b) are arranged next to one another, and the headers (6a, 6b; 7a, 7b) of two adjacent heat exchanger blocks (1a, 1b) are provided on their mutually confronting sides with orifices and are connected to one another in such a way that a flow connection occurs between the two headers (6a, 6b; 7a, 7b).

  • Patent number: 7051798
    Abstract: The invention relates to a plate heat exchanger with a heat exchanger block which has a multiplicity of heat exchange passages. The heat exchanger block has mounted on it a header which extends over at least part of one side of the heat exchanger block and makes a flow connection between part of the heat exchange passages. The header is provided with a fluid connection which is arranged essentially perpendicularly to that side of the heat exchanger block over which the header extends. (FIG.
