Definitions

  • the invention is in the field of plate heat exchangers.
  • Plate heat exchangers are used to transfer thermal energy between heat exchange fluids transferred to. At least two heat exchanger fluids flow through separate fluids Flow spaces formed between heat exchanger plates in the plate heat exchanger are.
  • the heat exchanger plates are usually arranged in a stack, which Is part of the plate heat exchanger.
  • the separate flow spaces are created using of openings formed in the heat exchanger plates and between the heat exchanger plates trained spaces.
  • a heat transfer between the at least two heat exchanger fluids essentially take place in the region of one central heat transfer section of the heat exchanger plates instead.
  • To transfer the Thermal energy flows through one of the heat exchanger fluids through a flow space on one Side of a heat exchanger plate and another heat exchanger fluid through a flow space on the other side of the heat exchanger plate. Through the heat exchanger plate heat is then passed between the two heat exchanger fluids flowing in countercurrent replaced.
  • plate heat exchangers in which the stacked heat exchanger plates each are designed as single-walled heat exchanger plates with a single plate element, plate heat exchangers are known, in which all relevant for heat transfer Heat exchanger plates of the stack are designed as double-walled heat exchanger plates are. Double-walled heat exchanger plates are made using two plate elements formed that closely at least in the area of the central heat transfer section come to rest against each other.
  • plate heat exchangers with a stack of double-walled heat exchanger plates can be used for applications where three separate flow spaces for three heat exchanger fluids with the help of the openings in the heat exchanger plates and the gaps between the heat exchanger plates in a plate heat exchanger are formed.
  • the object of the invention is to provide an improved plate heat exchanger with which the application possibilities for the use of plate heat exchangers are expanded.
  • the invention encompasses the idea of a plate heat exchanger with a stack of Heat exchanger plates that are permanently connected to each other and separated between them Flow spaces for at least two heat exchanger fluids are to be provided, in which a part of the heat exchanger plates usable for heat transfer each as a single-walled heat exchanger plate with one plate element and another Part of the heat exchanger plates usable for heat transfer each as a double wall Heat exchanger plate is designed with two plate elements.
  • plate heat exchangers can be manufactured, which as a single component sections in Have stacks of heat exchanger plates that meet various safety standards.
  • a plate heat exchanger enables plate heat exchangers for applications manufacture, in which to some extent the use of the more expensive double-walled Heat exchanger plates for the purpose of ensuring an adequate safety standard is necessary, but also at least a part of the heat exchanger plates can also be single-walled, because for some of the in the plate heat exchanger formed flow spaces a lower safety standard is sufficient.
  • Such use cases are particularly present when flow spaces in the plate heat exchanger are formed for more than two heat exchanger fluids. In this case it happens often before that regarding the heat transfer between one of the heat exchanger fluids and another of the heat exchanger fluids to ensure a higher safety standard is what the double-walled design of the heat exchanger plates requires. In terms of the heat transfer between the one heat exchanger fluid and another of the Heat exchanger fluids, however, a low safety standard is sufficient, so that the heat exchanger plates can be single-walled here.
  • the combination of double-walled and single-walled heat exchanger plates has this furthermore the advantage that in this way in a plate heat exchanger, which is usually is designed with double-walled heat exchanger plates, in some cases more efficient heat transfer used in connection with the single-walled heat exchanger plates can be.
  • using the combination of the two types of heat exchanger plates the manufacturing cost compared to the known, exclusively plate heat exchangers equipped with double-walled heat exchanger plates.
  • Figure 1 shows a schematic representation of an arrangement with several single-walled Heat exchanger plates 1 and several double-walled heat exchanger plates 2. Both Types of heat exchanger plates each have a central heat transfer section 3 and openings 4 in corner areas 5. In the area outside the openings 4 Embossments 6 are provided for forming surface structures. The embossing 6 support the spaced arrangement of the single-walled / double-walled heat exchanger plates 1, 2 for forming the flow spaces when using the single-walled / double-walled Heat exchanger plates 1, 2 in a plate heat exchanger.
  • a plate heat exchanger 20 is shown in front and side view.
  • the plate heat exchanger comprises a stack 21 with the arrangement of the single-walled / double-walled Heat exchanger plates 1, 2 according to Figure 1, the single-walled / double-walled Heat exchanger plates 1, 2 permanently connected to each other by means of soldering are.
  • the plate heat exchanger 20 further comprises two outer plates 22, 23 with Connections 24 for introducing and discharging the heat exchanger fluids. Between the several Heat exchanger plates 1, 2 are separate flow spaces for the connections 24 introduced / removed heat exchanger fluids formed.
  • the heat exchanger fluids are along the heat exchanger plates 1, 2 through the separate flow spaces in Countercurrent led.
  • the embossments 6 cause in the central heat transfer sections 3 of the single-walled / double-walled heat exchanger plates 1, 2 a highly turbulent Flow of the heat exchanger fluids between the several heat exchanger plates 1, 2.
  • FIG. 4 shows a cross-sectional illustration of the plate heat exchanger 20 according to FIG. 2 a line AA 'in Figure 2.
  • the stack 21 in the illustrated embodiment of the plate heat exchanger 20 comprises three double-walled heat exchanger plates 2a, 2b, 2c, each have two plate elements 2a ', 2a ", 2b', 2b" and 2c ', 2c ".
  • Both the single-walled as the double-walled heat exchanger plates 1, 2 have one opposite the plane of the central heat transfer section 3 raised edge 26.
  • an optional outer edge 27 is formed, which is bent outwards so that the outer edge 27 substantially parallel to the plane of the central heat transfer section 3 runs. In an alternative embodiment, can the outer edge 27 may be omitted.
  • heat exchanger fluid is what is due to a leak in one of the two plate elements 2a ', 2a “, 2b', 2b” or 2c ', 2c "between the plate elements 2a', 2a", 2b ', 2b “ or 2c ', 2c "and reaches the region of the edge 26 due to capillary action, already visible from the outside in an area 28.
  • the single-walled and double-walled heat exchanger plates 1, 2 each in separate stacks 21a, 21b summarized.
  • Heat exchanger plates 1, 2 can be provided, for example with several stacks of single-walled / double-walled heat exchanger plates 1, 2 in a plate heat exchanger.
