Definitions

  • the present invention refers to an easy-to-install plate heat exchanger.
  • plate heat exchangers are used in particular.
  • the arrangement of the plates, positioned one above the other to form a series of interconnected chambers, has the advantage of limiting the external dimensions while exchanging the same amount of heat.
  • the dimensions and number of the chambers are chosen according to the type of exchange process required.
  • these distribution chambers are produced by superimposing a series of plates at a certain distance in order to create a series of chambers arranged on top of each other and intercommunicating in succession.
  • the chambers are alternated so that a first group of chambers provides a path for the primary fluid, while the second group provides the path for flow of the secondary fluid.
  • each plate there are at least four apertures, provided peripherally with collars that extend in a substantially perpendicular direction to the plate itself.
  • a first plate is provided with a first pair of collars extending in one direction and a second pair extending in the opposite direction.
  • a second plate having the four apertures in the same dimensions as those corresponding to the first plate, is provided with a first pair of collars extending in a direction opposite to that of the first pair of collars of the first plate, and a second pair of collars extending in the opposite direction to that of the second pair of collars of the first plate.
  • Juxtaposing alternatively plates of the above two types and joining, for example by brazing or welding, the respective collars extending one against the other, we obtain the series of the two groups of distribution chambers that interact in the thermal exchange.
  • the aim of the present invention is therefore to improve the plate heat exchangers previously mentioned and in particular to produce a plate heat exchanger with greater efficiency.
  • a further aim of the present invention is to produce a plate heat exchanger that can be manufactured simply, with a minimum number of parts, while at the same time being particularly functional.
  • an easy-to-install plate heat exchanger is shown, indicated overall by number 11, which in the example illustrated, according to the present invention, is produced by superimposing a number of plates 12 and 13, of different type, alternating them.
  • Figure 3 shows a first type of plate 12: it is substantially rectangular-shaped, with rounded corners, and has four through apertures 14, 15, 16 and 17.
  • a first aperture 14 is provided near a corner between a longer side 18 and a shorter side 19 of the rectangle.
  • Said first aperture 14 constitutes an inlet for a first fluid, for example the primary fluid, and a second aperture 15, provided beside the first aperture 14, provides, according to the present invention, an outlet for said fluid, once the same has passed through distribution chambers 20 on the sides of the exchanger between superimposed plates 12 and 13.
  • the inlet and outlet of the first fluid are located along a short side of the exchanger, in this case the short side 19.
  • the exchanger provides a third aperture 16, also located near a corner between a second long side 21 and a short side 22 of the rectangle.
  • Said third aperture 16 provides an inlet for a second fluid, for example the secondary fluid, and a fourth aperture 17, located beside the third aperture 16, provides, according to the present invention, an outlet for said second fluid. Also in this case, said outlet is used once said second fluid has passed through distribution chambers 23 on sides of the exchanger between superimposed plates 12 and 13.
  • the inlet and outlet of the second fluid are located along a short side of the exchanger, in this case the short side 22.
  • each aperture is provided peripherally with collars that extend in a direction substantially perpendicular to the plate.
  • the first plate 12 is provided with a first pair of collars that extends in one direction and a second pair of collars that extends in the opposite direction.
  • the second plate which has apertures with the same dimensions as those of the first plate, is provided with a first pair of collars, extending in a direction opposite to that of the first pair of collars of the first plate, and a second pair of collars, extending in a direction opposite to that of the second pair of collars of the first plate.
  • the apertures in general are provided near corners of the rectangular shape of the plates, but they could also be arranged in a different position, on condition that their extension and connection collars can be aligned.
  • the plates are shaped for example by the provision of a series of ribs 26 and 28, generally obtained by drawing, on the plates 12 and 13; said ribs 26 and 28 have a suitable depth for obtaining a labyrinth path for the circulation of the two fluids of the exchanger.
  • the ribs 26 and 28 can be straight or in a herringbone pattern and in general the arrangement of the ribs 26 of the primary circuit plate 12 is different from that of the ribs 28 of the secondary circuit plate 13.
  • the primary circuit plate 12 and the secondary circuit plate 13 are provided with central profiles 29 and 30 which separate the distribution chambers 20 and 23 between the plates.
  • the inlets and outlets can be arranged in various ways; for example the inlets 14, 16 can be moved to the position of the apertures 15', 17. In this way, naturally, the outlets which were previously located in the apertures 15, 17 are now located in 14, 16.
  • the inlet and outlet apertures for the two primary and secondary fluids that exchange heat are connected, generally by threaded couplings, or even without, to respective primary (heating) circuit and secondary (sanitary) circuit.
  • the characteristics of the easy-to-install plate heat exchanger subject of the present invention are clear, and likewise the related advantages, including simple and dependable use of the same and a reduction in construction costs of the primary and secondary circuit plates due, above all, to the fact that the two types of plates 12 and 13 can be obtained by simply reversing the arrangement of a single plate constructed in this way. Simple installation derives also from the fact that the two plates 12 and 13 can be obtained from one single plate, the position of which is rotated alternatively by 180°.
