Definitions

  • This patent relates to plate heat exchangers and in particular to a new asymmetrical plate heat exchanger with ancillary connection channels. It relates, in particular, to a plate-type heat exchanger corresponding to the preamble of claim 1, as disclosed in EP 2 267 391 A1 .
  • Prior art includes plate heat exchangers comprising at least two separate circuits respectively for the circulation of a primary fluid and a secondary fluid, where those paths are defined by a plurality of exchange plates with facing surfaces, featuring ridges and hollows, generally distributed in a herringbone pattern.
  • Prior art heat exchangers are made by stacking the plates in question alternating the rotation of every other one by 180° so that the ridges and hollows of one plate are crossed with respect to the ridges and hollows of the adjacent plate.
  • the plates are called symmetric when the ridges and hollows are such that the sections of the channels of both paths used by the two fluids are substantially equal, that is, resulting in equal head loss with equal flows.
  • These heat exchangers are commonly used to heat water for domestic use using the hot water of the heating system.
  • the temperature of the heating system fluid must be much higher than that of the domestic water.
  • the heating water inlet temperature is 75°C and the outlet temperature may be about 60°C.
  • the inlet water temperature for domestic use may be about 10°C and the outlet temperature about 55°C.
  • Prior art also includes plates specially shaped in such a way that the section for the heating fluid is wider than the section for the domestic hot water, and therefore the head losses are differentiated.
  • the prior art includes the so-called asymmetric heat exchangers, that is, formed by plates comprising ridges with a different shape than the hollows, such as, for example, flat ridges to make the section of the channel even wider.
  • asymmetric heat exchangers that is, formed by plates comprising ridges with a different shape than the hollows, such as, for example, flat ridges to make the section of the channel even wider.
  • Plates having different head losses with equal flows are also known, obtained by increasing the pitch of the ridges, that is, the distance between the ridges of two adjacent channels.
  • This type of heat exchanger is suitable for the exchange between water and cooling fluid, where the water flows through the path having lower head losses.
  • the narrowest channels are excessively smaller than the wider channels.
  • Heat exchangers with plates where the depth of the secondary hollow is at least 40% and preferably 50% of the depth of the larger hollow are known. Heat exchangers where the depth of the secondary hollows is diversified on different plates are also known.
  • exchangers where a single plate has secondary hollows having two different depths used in two different areas of the plate are also known.
  • One drawback is the fact that the pitch of the welding points is not constant and therefore there are areas where the plates may be less rigid, giving rise to localized deformations that impair the functioning and efficiency of the exchanger.
  • the main object of the present invention is to create paths with different head losses, while maintaining symmetrically distributed welding points as in the heat exchangers of the known type, to the benefit of resistance to pressure.
  • Another object of the present invention is to increase the turbulence of the flow in at least one path.
  • the new asymmetric plate heat exchanger includes in its main parts at least one series of superimposed plates in a pack, brazed together with possible perimeter seals to confine the fluids inside, and passage holes for at least two exchange fluids, these holes also having seals alternately arranged so as to convey the two fluids in the spaces between the plates, following at least two hydraulically isolated paths.
  • the heat exchanger therefore comprises at least two separate paths for a primary fluid and a secondary fluid, each of these two paths being defined by a pair of the facing plates, equipped with alternating ridges and hollows arranged substantially in a herringbone pattern, that is, arranged in two directions which intersect with each other, and where those two paths have different head losses.
  • the heat exchanger includes, in particular, two different types of plates, arranged alternately in the pack forming the heat exchanger, where the first type of plate comprises ridges and hollows at a constant pitch and constant height or depth.
  • the second type of plate also comprises ridges and hollows at a constant pitch and constant height or depth but has a particular shape as hereinafter described and claimed.
  • all the hollows of the plate have a constant depth, except for localized raised portions, that is, having a length much shorter than the length of the hollow.
  • One or more of the elevations are distributed along each hollow and variously distributed. These localized raised portions of one side of the plate correspond, on the opposite side of the plate, to localized lowered portions on the ridges.
  • a secondary path is created, with a greater head loss, formed by main channels, along the hollows of the two facing plates, where there are constrictions in the channels created by the raised portions, suited to increase the turbulence of the fluid and increase the head loss.
  • a primary path with a lower head loss is created between them, formed by two series of channels, a first series of main channels along the hollows, and a second series of ancillary channels, transverse to the main channels, created by the lowered portions that put the main channels in communication transversely.
  • these hollows and ridges are arranged in a herringbone pattern, that is, arranged specularly with respect to a central plane, thus creating two directions which intersect each other.
  • These raised portions and corresponding lowered portions are distributed preferably aligned along directions not intersecting the direction of the ridges and hollows.
  • these raised portions and lowered portions are aligned in a direction parallel to the direction of the ridges and hollows of the specular half.
  • Each type of plate is in fact made on a dedicated line so that, from each line, the plate obtained is already correctly positioned to be superimposed on the plate coming from the second line. Therefore, the need to rotate the plate 180° as in the assembly procedures of the known type of heat exchangers which use plates which are all the same is eliminated.
  • the ridges and hollows on one side of the plate are hollows and ridges on the opposite side.
  • ridges and hollows are relative to the side being observed. Therefore, the raised portions provided for in this patent may be placed on both the hollows and the ridges with an opposite effect on the opposite side of the same plate.
  • the main parts of the new asymmetric plate exchanger comprise plates (A, B) superimposed in a pack, brazed together with possible perimeter seals, to confine the fluids inside, and holes (C) for the passage of the exchange fluids, these holes (C) are themselves brazed together at the edges or equipped with seals alternately arranged so as to convey the two fluids in question in the spaces between the plates along at least two hydraulically isolated paths (1, 2) with different head losses.
  • the heat exchanger comprises at least two paths (1, 2) separated respectively for a primary fluid and a secondary fluid, each of the two paths (1, 2) being defined by a pair (A, B) of the aforementioned facing plates.
  • the heat exchanger includes two different types of plates, arranged alternately in the pack making up the heat exchanger, as shown for example in Figure 3 .
  • the first type of plate (A) comprises a plurality of alternating ridges (A2) and hollows (A3), arranged in a herringbone pattern, that is, arranged specularly with respect to a central plane (A4) according to two directions (X1, X2) intersecting each other.
  • Said ridges (A2) and hollows (A3) have a modular or constant pitch (A5) and have a constant height or depth, that is, the distance (A6) between the top of the ridges and the bottom of the hollows is constant.
  • the second type of plate (B) comprises a plurality of alternated ridges (B2) and hollows (B3), arranged in a herringbone pattern, that is, arranged specularly with respect to a central plane (B4) according to two directions (X1, X2) intersecting each other.
  • Said ridges (B2) and hollows (B3) have a modular or constant pitch (B5), equal to or different from the pitch (A5) of the first type of plate (A).
  • all the hollows (B3) of the plate (B) have a constant depth (B6), with the exception of localized raised portions (B31), that is, having a length much shorter than the length of the hollows (B3).
  • These raised portions (B31) or lowered portions (B21) are distributed along each hollow (B3) or ridge (B2), for example, one or more for each hollow (B3) or ridge (B2), at a modular or constant distance.
  • Each of these paths (1, 2) of the two fluids is created by placing one plate of the first type (A) with one plate of the second type (B), so that the hollows (A3, B3) and ridges (A2, B2) of the two plates are crossed.
  • the path in which the primary fluid circulates, or the primary path (1) is obtained by placing a plate of the first type (A) with a plate of the second type (B) on the side of the lowered portions (B21) of the ridges (B2).
  • This primary path (1) has a lower head loss and is formed by two series of channels (11, 12).
  • the first series of channels, or the main channels (11) are formed by the hollows (B3, A3) of the two plates (B, A) facing each other, while the second series of channels, or ancillary channels (12) are transverse to the main channels (11) and created by the lowered portions (B21) that put the main channels (11) in communication transversely.
  • the raised portions (B31) and corresponding lowered portions (B21) are distributed preferably aligned along directions (Y1, Y2) intersecting the direction of the ridges (B2) and hollows (B3).
  • the lowered portions (B21) are aligned in a direction (Y1, Y2) parallel to the direction (X1, X2) of the hollows (B3) of the opposite specular half, and in particular are aligned with the extension of the lowered portion (B3) of the opposite specular half, thereby creating a network of main (11) and crossed secondary (12) channels.
  • This path in which the secondary fluid circulates, or the secondary path (2) is obtained by placing the plate of the first type (A) with the plate of the second type (B) on the side of the raised portions (B31) of the hollows (B3).
  • This secondary path (2) has a greater head loss and is formed by a series of channels (21) formed by the hollows (B3, A3) of the two facing plates (B, A), where in the main channels (21) of the secondary path (2) there are narrowed portions (22) created by the raised portions (B31), which reduce the section for the passage of the fluid, increasing the turbulence of the fluid and increasing the head loss.
