Definitions

  • the invention relates to a plate heat exchanger according to the preamble of patent claim 1.
  • the heat exchanger block of a plate heat exchanger consists of several layers of heat exchange passages, which are each delimited by separating plates against each other. End strips and cover plates form the outer frame of the heat exchanger block. Within a layer, further separating strips can be provided which separate heat exchange passages for different material flows from one another.
  • headers are welded over the inlet and outlet openings of the heat exchange passages, which are provided with a fluid connection.
  • headers are usually used semi-cylindrical shells, but may also have other shapes.
  • the walls of the header typically form an outside angle of 90 ° with the corresponding side of the block (see, for example, "The Standards of the Brazed Aluminum Plate-Fin Heat Exchanger Manufacturers' Association, ALPEMA," Second Edition, 2000, FIG. 5).
  • a "fluid port” serves to supply or discharge fluid into or out of the header.
  • a pipe socket which are arranged in the half-cylinder jacket of the header opposite the inlet and outlet openings; At these pipe sockets, the pipes for the incoming and outgoing fluid flows are connected.
  • plate heat exchangers can be used for the simultaneous heat exchange of many fluid streams.
  • appropriate headers are then to be attached above the respective inlet and outlet openings of the heat exchange passages and provided with pipelines (see, for example, "US Pat. The Standards of the Brazed Aluminum Plate-Fin Heat Exchanger Manufacturers' Association, ALPEMA, Second Edition, 2000 , Figure 1-1).
  • side of a heat exchanger block is to be understood geometrically, that is, it is a flat surface of the heat exchanger block, which is generally cuboid.
  • the invention has for its object to improve the flow characteristics within the header.
  • This object is achieved in that the side of the heat exchanger block and at least a portion of the wall of the header form an outer angle which is smaller than 90 °.
  • Outside angle is understood to mean the angle outside the header. In the event that the relevant wall portion of the header is accurately connected to the edge of the block, this outer angle is formed by the angle of the wall with the imaginary continuation of the block side beyond this edge.
  • the non-perpendicular connection of the header wall to the block side causes the flow area in the header to be increased without having to increase its base area facing the heat exchanger block.
  • an improved flow characteristic is achieved inside the header, which in turn causes a reduced pressure loss and a more uniform distribution of the fluid to the passages.
  • more than half of a cylinder jacket is used as a header instead of a half cylinder. If you move the cylinder axis of the header from the side of the heat exchanger with a constant diameter by about 10% of the cylinder diameter, the pressure loss can be reduced by about 35%.
  • This advantage is achieved even with the same nominal size of the header (ie the same connection dimensions and the same wall thickness) and even reduced footprint.
  • this eccentricity can be varied continuously.
  • the flow cross-section of the header can thus specifically adapted to the particular application and in particular a misallocation can be efficiently avoided.
  • the invention can also be applied to other types of headers, for example those with an oval, asymmetrical and / or angular cross-section.
  • the outer angle is preferably 87 ° or less, in particular 81 ° or less, in particular 75 ° or less and is at least equal to 40 °, in particular at least equal to 55 °, in particular at least equal to 65 °.
  • the invention is realized in that the header over a part of its length or over its entire length has a cross section in the form of a circle segment with an opening angle of more than 180 °.
  • the cuboid heat exchanger block 1 configured header 2, the fluid port 3 and the subsequent piping 4.
  • the illustrated header can serve as an inlet or outlet for a fluid.
  • the plate heat exchanger according to the invention further headers. These may be conventional or just like the header shown. Any mixture between inventive and conventional headers is possible within the scope of the invention.
  • the header 2 is arranged on the side 5 of the block 1 and formed in the form of a cylinder jacket segment with an opening angle 6 of more than 180 °, for example about 200 °.
  • the wall 7 of the header 2 forms an outer angle 8 with the side 5. (In order to make the outer angle visible, a tangent surface 9 of the header wall 7 is shown in FIG. 2).
  • the two embodiments differ by the orientation of the fluid port 3.
  • the fluid port 3 is oriented perpendicular to the side 5 of the block 1.
  • the fluid thus flows through the pipeline 4 parallel to the side 5 or from.
  • a baffle 10 located in the pipe 4, a baffle 10, as in the older German patent application 102005055676.0 (internal file number of the applicant: P05271-DE / AVA, filing date: 22.11.2005) and the corresponding applications.
  • the baffle is not arranged in the present case on the cylinder axis of the pipeline, but at a distance 11 to this.
  • the pipeline 4 has a cylindrical shape and continues to the left (not shown in FIG. 1).
