Definitions

  • the heat exchanger block of a plate heat exchanger consists of several layers of heat exchange passages, each against the other by dividers are delimited. End strips and cover plates form the outer frame of the Heat exchanger block. Additional separating strips can be provided within one layer be the heat exchange passages for different material flows from each other separate.
  • the heat exchanger blocks are not according to the invention Pipe socket and a manifold connected on the flow side, but the Fluid connection of the header of a heat exchanger block is made directly with the Fluid connection of the header of an adjacent heat exchanger block connected.
  • the fluid connection preferably extends over the entire cross section of the Headers and will keep the cross section on the adjacent header connected. The result is a continuous header that spans all Extends heat exchanger blocks.
  • the Heat exchanger blocks are preferably installed with a spacer connected to each other, usually welded together. Can be used as a spacer for example, an appropriately shaped sheet or a bar can be used.
  • the spacer is in the area of the header is arranged that the side of the header facing the heat exchanger blocks is completely covered by the spacer in the area of the gap.
  • the space inside the header is covered by the header itself, for example a semi-tubular shell, the side walls of the Heat exchanger blocks and part of the spacer limited.
  • a plate heat exchanger is shown schematically as he is also known from the prior art.
  • the plate heat exchanger has one Heat exchanger block 1 with a variety of heat exchange passages that the For the sake of clarity, the figures are not shown.
  • the inputs and Outlet openings of a group of heat exchange passages are located in the Area 2 on a side wall 3 of the heat exchanger block 1 or in area 4 on the bottom 5 of the heat exchanger block 1.
  • On the areas 2, 3 with the Einund Outlet openings are welded on semi-cylindrical headers 6, 7.
  • the headers 6, 7 are designed as semi-cylindrical shells with base areas 8, 9, 10, 11.
  • baffles 23, 24 are arranged, which the space within the Divide headers 6, 7 into a flow area 25 and a distribution area 26.
  • the Baffles 23, 24 are provided with a plurality of openings so that a gas and Liquid exchange between the flow region 25 and the Distribution area 26 is possible.
  • Both pipes 12, 13 are on the same side of the Heat exchanger blocks 1.
  • the connection of the heat exchanger and the others Piping is therefore easily possible.
  • the heat exchanger blocks 1a, 1b are first of all with their respective headers 6a, 6b, 7a, 7b subjected to a leak test and a pressure resistance test. To all bases 8a, 9a, 10a, 11a of headers 6a and 7a are successful of the heat exchanger block 1a and the bases 8b, 9b of the headers 6b, 7b of the Heat exchanger blocks 1b separated. On the two sides facing each other the header 6a, 6b, 7a, 7b is separated, as in FIG. 5 by dashed lines Lines 20 shown, oblique to the axis of the semi-cylindrical headers 6a, 7a, 6b, 7b. The base areas 8a, 9a of the heat exchanger block 1a become perpendicular to the axis the semi-cylindrical header 6a, 7a cut off.
  • the two heat exchanger blocks 1a, 1b are then at their lower ends a sheet 16 welded together.
  • the U-shaped sheet 16 is so on Heat exchanger blocks 1a, 1b attached that the base of the U-shaped plate 16 the Bottom sides 5a, 5b of the two blocks 1a, 1b connect so that one continuous level results.
  • the two Heat exchanger blocks 1a, 1b also connected to a U-shaped plate 27, whose base is in the plane of the drawing and from the upper edge 21a, 21b of the heat exchanger blocks 1a, 1b to the lower edge 22a, 22b of the headers 6a, 6b extends on which the semi-cylindrical header shell on the heat exchanger block 1a, 1b hits.
  • a fluid is supplied via pipeline 12, which fluid flows into the through the baffle 23 separated flow area 25 of the header 6a and over the pie-shaped connector 18 in the flow area 25 of the header 6b flows.
  • the baffles 23 of the two headers 6a, 6b have a plurality of Openings through which the fluid flows into the flow-reduced distribution areas 26 arrives.
  • the fluid is applied to the corresponding heat exchange passages of the heat exchanger blocks 1a, 1b distributed.
  • the headers 7a, 7b are also in one by a baffle 24 flow-reduced area 26 and a flow area 25 divided.
  • flow-calmed region 26 essentially serves for collecting and bringing together the fluid exiting the heat exchange passages and the flow region 25 for discharging the fluid to the pipeline 13.
