Definitions

  • Brazed plate heat exchangers made of aluminum are used in numerous systems at various pressures and temperatures. They are used for example in the separation of air, the liquefaction of natural gas or in plants for the production of ethylene.
  • the in FIG. 1 illustrated plate heat exchanger 1 is used to heat exchange five different process streams A, B, C, D and E.
  • the heat exchanger 1 is block-shaped and equipped with a variety of means 6 for supply and discharge of the individual process media. These means 6 are described below and in the context of this application referred to as nozzle.
  • the heat exchanger also has a plurality of means 7 for distributing and collecting the individual process streams A, B, C, D and E, which are referred to below and in the context of this application as headers.
  • the plate heat exchanger 1 consists of a plurality of stack-shaped arranged passages 3, which are separated by partitions 4 from each other.
  • the various media flow.
  • the heat exchange takes place indirectly via the heat contact, which is produced by the cover plates 5 and by the wave-shaped structure arranged in the passages (hereinafter referred to as fins in the context of this application).
  • the individual media A, B, C, D and E are guided in the header 7 and distributed to the respectively provided, stacked passages 3.
  • distributor fins 2 In the entrance area of the passages there are so-called distributor fins 2, which ensure an even distribution of the medium within the individual passages 3. The media thus flow transversely to the shaft direction of the fins 3 through the passages 3.
  • the fins 3 are connected to the baffles 4, whereby an intensive mecanical modifier is produced. This allows a heat exchange between two different media that flow in adjacent passages 3. As seen in the flow direction at the end of the passage are similar distributor fins 2, which lead the media from the passages in the header 7, where they are collected and withdrawn through the nozzle 6. The individual passages 3 are completed by so-called sidebars 8 to the outside. The entire heat exchanger block is limited by cover plates 5 to the outside.
  • Such plate heat exchangers are ideal for heat exchange of at least 2 media. By appropriate construction, however, as in FIG. 1 shown, even more than 2 media participate in the heat exchange. This allows a very effective process management and effective heat and cold utilization.
  • Such plate heat exchangers are brazed, for example, aluminum.
  • the individual passages with the fins, distributor fins, cover plates and sidebars are stacked on each other, provided with solder and brazed in an oven. On the resulting block then header and neck are welded.

  • the sidebars therefore form according to the prior art, virtually a frame on the cover plate.
  • This frame is welded to the cover plate of the adjacent module and made such a connection between two modules.
  • the two connected modules thereby form a new heat exchanger block, which is larger than the actual geometry of the brazing oven allowed. In this way, any number of modules can be connected together to form an arbitrarily large heat exchanger block.
  • two adjacent modules have at least one common header.
  • the present invention has for its object to design a plate heat exchanger with at least two modules, as described above, such that the most rigid and firm connection between two immediately adjacent modules is made. For example, forces due to thermal stress between two modules should be minimized and the mechanical strength of the entire block consisting of at least two modules should be increased.
