Definitions

  • the present invention relates to a plate heat exchanger, particularly but not exclusively useful for condensing and evaporating refrigerating fluids.
  • plate heat exchangers are devices used to transfer heat energy from one fluid to another and are constituted by a plurality of mutually facing metal plates shaped so as to form, in the spaces between two adjacent plates, a corresponding plurality of passage circuits for the fluids.
  • the plates are usually rectangular, are commonly obtained by pressing and have appropriate corrugations, substantially in the central region, and generally have four openings at their corners.
  • the corrugations are designed to stiffen the plates and to improve heat exchange, while the openings are designed to provide the ducts for the distribution and recovery of the fluids.
  • the plates are sealed at their perimeter and at their input and output ducts by means of gaskets or by welding and/or braze welding, so as to prevent the escape of the fluids from the respective ducts and from the circuits formed between the facing plates.
  • Operation of plate heat exchangers consists in producing the alternating flow, in the passage circuits, of a refrigerating fluid, which evaporates or condenses, and of a heat transfer fluid, which becomes cooler or warmer.
  • the aim of the present invention is to provide a plate heat exchanger with improved performance with respect to exchangers currently in use while maintaining a low production cost and achieving high reliability and durability.
  • a plate heat exchanger comprising a plurality of mutually facing plates that are hermetically coupled at at least one substantially peripheral portion and form at least two separate circuits for at least two fluids, each one of said plurality of plates having access ports that provide input ducts and output ducts for said at least two fluids, characterized in that at least one portion of at least one face of at least one of said plurality of plates is uneven.
  • FIG. 1 is a partially sectional perspective view of the plate heat exchanger according to the invention.
  • FIG. 2 is a perspective view of a plate of the plate exchanger according to the invention.
  • FIG. 3 is an enlarged-scale plan view of a portion of a plate of the heat exchanger according to the invention, with a surface that is uneven due to the presence of microengravings.
  • the plate heat exchanger generally designated by the reference numeral 1 , comprises a plurality of mutually facing plates 2 and generally at least two ducts, an input duct 3 a and an output duct 3 b , for a respective fluid.
  • the plates 2 are usually coupled hermetically to each other either by interposing gaskets, not shown in the figures, at a substantially peripheral portion 4 and at the ducts 3 a and 3 b , or by welding or braze welding.
  • each plate 2 has, as shown more clearly in FIG. 2, a main corrugation, generally arranged in a herringbone pattern, which is adapted to increase and facilitate the exchange of heat among passage circuits formed between two adjacent plates 2 .
  • At least one of the plates 2 has at least one face that comprises at least one uneven portion 5 .
  • said portion 5 is uneven thanks to the presence of microengravings and/or microgrooves and/or microindentations.
  • each plate 2 has at least one completely uneven face.
  • the adjacent plates 2 are assembled so that their completely or partially uneven faces form at least the ducts for the refrigerating fluid.
  • the uneven portion 5 of the plates 2 can be obtained in various manners. These manners can include, merely by way of non-limitative example, mechanical processes such as for example sanding, brushing, satin finishing, sandpapering, coining, drawing, rolling, mechanical incision and pressing.
  • the uneven portion 5 can also be obtained by way of processes of the chemical, electrochemical, electronic or chemical-physical type: these processes can include for example controlled corrosion, metallization, melting, plating, explosion, electronic or laser alteration, photoengraving, et cetera.
  • the materials used may be any according to requirements.
