Definitions

  • the subject of the invention is the shape of the heat exchange area of the heating plate of the plate heat exchanger.
  • Plate heat exchangers consists of heating plates laid alternately. Due to the way of their construction, one can differentiate the disassembled (screwed, gasketed) heat exchangers, not disassembled heat exchangers (soldered, welded, shell-plate), and partly disassembled heat exchangers (semi-welded gasketed).
  • the essence of the construction of disassembled plate heat exchangers is the pressure of dis ountable heating plate package using the construction of frame and screws. Heating plates with a corrugated pattern contact each other by the tops of the notches are and guarantee tightness and creating channels, in which the working medium flows.
  • Brazed plate heat exchangers have heating plate packages that are permanently brazed together. They can be brazed with copper (common solution), nickel or stainless material to ensure adequate anti-corrosiveness in an aggressive work environment.
  • copper common solution
  • nickel nickel
  • stainless material to ensure adequate anti-corrosiveness in an aggressive work environment.
  • the method of joining plates deserves particular attention. They are welded in pairs, then sealed with gaskets. One of the working media flows through the channels formed by the heating plates, then the cooling fluid or the cooled fluid flows between the pairs of such plates.
  • the plate package is located in the shell.
  • each subsequent heating plate is rotated by 180°.
  • Such positioning and screwing, soldering, gluing or welding allows to create independent channels by means of which the heating and cooling medium will be able to participate in the heat exchange process.
  • the shape of the heat exchange area of the heating plate of the plate heat exchanger has a strong influence on the heat exchanger work parameters.
  • the important feature that characterizes each heat exchanger is the pressure drop. To determine the flow pressure drop, the pressure value at the exchanger input and the outlet are measured. The difference in the values obtained defines the flow pressure drop. In the case of heating plates with a corrugated pattern of high chevron angle geometry, the flow pressure drop is higher and the thermal efficiency is higher, while using lower chevron angle results in lower flow pressure drop, but also in decreased heat exchange.
  • the main advantages of plate heat exchangers include efficiency of heat exchange, compact design, small fluid volume, reliability and safety during work, flexibility of heat exchanger selection based on operating parameters, relatively low price in relation to the real efficiency of the device, relatively high turbulence of the working medium inside heat exchangers.
  • the number of points furthest from the axis along which the apex line of the corrugation is drawn, and at the same time lying on the apex line of the corrugation is at least 2 for every 200 mm of the length of the axis along which the apex line of the corrugation is drawn;
  • the apex line of the corrugations is preferably in the form of a polygonal curve, the angle between the axis along which the apex line of the corrugation is drawn and the axis parallel to the apex line of the corrugation, is the opening angle.
  • the heating plate (1 ) is part of a alternately laid heating plates package (6) being part of a plate heat exchanger (5).
  • the heat exchanger (5) may have cover plates (7) and nozzles (8) used for mounting and connecting heat exchanger (5) elements.
  • the elements of the heat exchanger (5), in particular the heating plates (1 ) are made of stainless steel, but can also be made of titanium, its alloys or of various metals and/or metal alloys and/or non-metals and/or plastics and or composite materials. Connecting the components of the heat exchanger (5) is done through the soldering process, but it can also be done by welding or gluing, or by screwing. This provides a wide range of applications in the industry, including energy, pharmaceutical, food, petrochemical, chemical, mining, at pool installations, HVAC, HVACR and sewage treatment plants.
