Definitions

  • the present invention refers to a plated heat exchanger with simplified production.
  • an exchanger there is an energy transfer between a fluid at a certain temperature and one or more fluids at different temperatures.
  • the fluids normally in liquid or gas state, are isolated from each other and one of the fluids can consist of atmospheric air.
  • Plated heat exchangers have become widespread relatively recently and offer different advantages including, with the same heat exchanged, substantial containment of the outer size.
  • Such heat exchangers comprise a series of distribution chambers in which the fluids circulate, the characteristic size and the number of chambers being selected according to the type of exchange process.
  • the distribution chambers are realised by juxtaposing a series of plates: a certain distance is foreseen between one plate and the next, so as to create a series of stacked chambers.
  • two groups of chambers can be identified, alternating with each other.
  • One group is crossed by a primary fluid, whereas in the other a flow of secondary fluid is foreseen, also known as sanitary fluid, with particular reference to the case in which the exchanger is used in domestic boilers.
  • each group is connected together. This is realised by foreseeing on each plate at least four openings peripherally equipped with necks which extend in a direction substantially perpendicular to the plate itself.
  • a first pair of necks is foreseen which extends in one direction and a second pair which extends in the opposite direction.
  • a second plate having the four openings of a size analogous to those at the first plate, a first pair of necks is foreseen, which extends in an opposite direction to that of the first pair of necks of the first plate and a second pair of necks, which extends in an opposite direction to that of the second pair of necks of the first plate.
  • the purpose of the present invention is thus that of improving plated heat exchangers mentioned previously and in particular that of realising a plated heat exchanger with simplified production.
  • Another purpose of the present invention is that of realising a plated heat exchanger with simplified production which is particularly reliable, simple and functional.
  • a plated heat exchanger with simplified production is shown, wholly indicated with 10, which in the illustrated example, according to the present invention, is realised by juxtaposing a plurality of plates 20 and 30, alternating with each other.
  • Figure 4 shows a first type of plate 20, also known as a primary circuit plate or heating circuit plate: it is substantially quadrangular, generally rectangular with rounded corners, and it has at least four through openings 21, 22, 23 and 24.
  • a first opening 21 is realised near to a longer side of the rectangle, in an intermediate position of such side.
  • a second opening 22, a third opening 23 and a fourth opening 24 are, on the other hand, realised near to three corners of the rectangle.
  • Figure 3 shows a second type of plate 30, also known as a secondary circuit plate or sanitary circuit plate: it is substantially quadrangular, generally rectangular with rounded corners, it is of a size analogous to that of the primary circuit plate 20 and it has at least four through openings 31, 32, 33 and 34, of an analogous size and realised at respective through openings 21, 22, 23 and 24 of the primary circuit plate 20 itself.
  • a first opening 31 is realised near to a longer side of the rectangle, in an intermediate position of such side.
  • a second opening 32, a third opening 33 and a fourth opening 34 are, on the other hand, realised near to three corners of the rectangle.
  • the through openings 21, 22, 23 and 24 of the primary circuit plate 20 and the through openings 31, 32, 33 and 34 of the secondary circuit plate 30 are foreseen on the respective plates 20 and 30 on planes which are at two different heights.
  • a first pair of openings 21 and 23 which is situated on a plane at a first height and a second pair of openings 22 and 24 which is situated on a plane at a second different height lower than the first height is foreseen.
  • a first pair of openings 32 and 34 which is situated on a plane at a first height and a second pair of openings 31 and 33 which is situated on a plane at a second different height lower than the first height is foreseen.
  • the primary and secondary circuit plates 20 and 30 are equipped with a series of ribs 26 and 36, respectively, generally obtained with a drawing operation on the plates 20 and 30 themselves.
  • Such ribs 26 and 36 have a depth which approximately reaches the second height of the plates 20 and 30, respectively.
  • the ribs 26 and 36 advantageously have a rectilinear direction or a skew direction.
  • the orientation of the ribs 26 of the primary circuit plate 20 is different from that of the ribs 36 of the secondary circuit plate 30.
  • the primary and secondary circuit plates 20 and 30 are equipped with addressing profiles 25 and 35 respectively, which extend in a direction substantially perpendicular to the plates 20 and 30.
  • the heat exchanger 10 is realised by juxtaposing a series of plates 20 and 30, alternating a primary circuit plate 20 and a secondary circuit plate 30.
  • the plates 20 and 30 are joined together by connecting, generally by brazing or welding, the planes surrounding the pairs of opening 21 and 31, 22 and 32, 23 and 33, 24 and 34, which in juxtaposition are situated at coinciding heights. This connection is clear if one looks at figure 5 and one thinks of further lowering the plate 30 on the plate 20 until the hole 33 coincides with the hole 23.
  • the ribs 26 and 36 of the plates 20 and 30 are brazed or welded together in a discrete series of points of contact, deriving from the different orientation of the ribs 26 and 36 of two contiguous plates 20 and 30.
  • two groups of chambers can be identified, alternating with each other.
  • One group is crossed by a primary fluid, whereas in the other group a flow of secondary fluid is foreseen, also known as sanitary fluid, with particular reference to the case in which the exchanger is used in domestic boilers.
  • the distribution chambers of each group are connected together through the joining of the planes surrounding the pairs of openings 21 and 31, 22 and 32, 23 and 33, as explained above.
  • the addressing profiles 25 and 35 are foreseen in identical positions of the two plates 20 and 30 respectively: in the joining of two contiguous plates 20 and 30, the respective addressing profiles 25 and 35 extend towards each other and are for example brazed together. In this way paths for a flow of fluid are created which makes the fluid itself cross a path which mostly covers the whole surface of the plates 20 and 30 which are contiguous.
  • a flow of secondary fluid can go from the first opening 31 to the third opening 33 making it also pass near to the fourth opening 34: this is obtained by placing an L-shaped addressing profile 35 around the first opening 31, which prevents direct passage of the secondary fluid from the first opening 31 to the third opening 33.
  • a primary fluid can go from the second opening 22 to the fourth opening 24.
  • the plate which closes the heat exchanger 10 at the top has four through openings at the openings 21, 22, 23 and 24 of the primary circuit plates 20 and at the openings 31, 32, 33 and 34 of the secondary circuit plates 30.
  • Such openings, where the primary and secondary fluids which exchange heat enter and exit, are connected, generally with threaded joints, or even without, to respective primary or heating and secondary or sanitary circuits.
  • FIGS 8 and 9 illustrate a second possible practical embodiment of the invention, where components which are the same as and/or equivalent to those illustrated in figures 1-7 carry the same reference numerals increased by 100.
  • the primary and secondary circuit plate 120 and 130 are equipped with addressing profiles 125 and 135 respectively, which extend in a direction substantially perpendicular to the plates 120 and 130 and which are foreseen in identical positions as the two plates 120 and 130 respectively.
  • the addressing profiles 125 and 135 are L-shaped and are placed between the first opening 121 and 131 and the fourth opening 124 and 134, preventing direct passage for example of the secondary fluid from the first opening 131 to the fourth opening 134.
  • FIGS 10 and 11 illustrate a third possible practical embodiment of the invention, where components which are the same as and/or equivalent to those illustrated in figures 1-7 carry the same reference numerals increased by 200.
  • a first opening 221 is realised near to a longer side of the rectangle, in an intermediate position of such a side.
  • a second opening 222, a third opening 223 and a fourth opening 224 are, on the other hand, realised near to three corners of the rectangle: more specifically, the second opening 222 and the fourth opening are positioned at the longer side opposite the one at which the first opening 221 is realised, whereas the third opening 223 is realised at the shorter side of the second opening 222.
  • the primary and secondary circuit plate 220 and 230 are equipped with addressing profiles 225 and 235 respectively, which extend in a direction substantially perpendicular to the plates 220 and 230 and which are foreseen in identical positions as the two plates 220 and 230 respectively.
  • the addressing profiles 225 and 235 are arranged around the first opening 221 and 231, with one wall open towards the corner without openings, preventing direct passage for example of the secondary fluid from the first opening 231 to the second opening 232.
