Definitions

  • the present invention relates to the field of aeraulic systems, in particular of conditioning systems.
  • the present invention more specifically, relates to a fluid distributor assembly suitable for use in a heat exchanger, in particular an evaporator.
  • Heat exchangers used in conditioning systems are devices that, in the most general terms, comprise a casing - or mantle - inside which is housed a tube bundle. Within the tube bundle, a service fluid flows to exchange heat with a process fluid at a different temperature.
  • the service fluid is typically an evaporating refrigerant fluid that circulates inside the tube bundle and cools the process fluid.
  • the latter passes externally to the tube bundle housed within the mantle, passing through the heat exchanger.
  • a supply pipe feeds the heat exchanger with refrigerant fluid, engaging it at a head unit - or manifold - thereof.
  • the exchanger is generally equipped with a dedicated distributor device.
  • JPH1089885 discloses a tank for a heat exchanger wherein an inlet section is equipped with a junction element provided with sacrificial corrosion members.
  • the known distributor devices typically provide a plurality of fed conduits each engaging a respective tubular element of the tube bundle. Solutions of this type however have the drawback of being constructively complex due to expensive and sophisticate mechanical machining of the fed conduits connecting structure in order to maintain desired outlet conditions while conveying the fluid in each tube of the bundle.
  • the technical problem placed and solved by the present invention is then to provide a fluid distributor assembly, in particular a refrigerant fluid, within the tube bundle of a heat exchanger that allows to overcome the above-illustrated drawbacks with reference to the prior art.
  • the fluid distributor assembly according to present invention is structurally simple and economical to be realized, due to the presence of a lamination unit housed in a seat of the head unit in such a way that, a mixing chamber of refrigerant fluid that feeds the latter is defined.
  • the fluid distributor assembly comprises direction means provided with an impact surface and configured so as to direct the fluid outflowing from said lamination unit along a substantially orthogonal direction with respect to a fluid inlet direction into apertures of the tube plate engaging the tube bundle of the exchanger.
  • This solution overcome the need to provide complex, tricky and high-costly working process of single-engagements conduits intended to engage a respective tubular element of the tube bundle to feed each tube individually. Furthermore, the presence of said direction means allows to create fluid agitation conditions in the mixing chamber prior to its entry into the tube bundle. Particularly, said orthogonal flow to the fluid inlet direction into the tube plate is generated so as to sequentially lick the tube plate apertures and to allow each tube to suck the required amount of refrigerant, according to a kind of dynamical "self-regulation".
  • FIG 1 an exploded view of a preferred embodiment of a fluid distributor assembly 1, in particular a refrigerant fluid, according to the present invention is illustrated by way of example and not for limitative purposes.
  • the distributor assembly 1 of the present invention is intended for a preferred use in heat exchangers, preferably evaporators, such as direct evaporators.
  • the distributor assembly 1 is shown in association with a tube plate 100, the latter being an element to which the distributor assembly 1 is intended to be coupled.
  • the tube plate 100 is a plate with a circular geometry, exemplifying the tubular plates used in the considered technical field.
  • the tube plate 100 shown is not limitative for the purposes of the present invention.
  • the distributor assembly 1 comprises a head unit 10 - or manifold - configured to receive the refrigerant fluid inletting the heat exchanger and is intended to be coupled to the tube plate 100 at a coupling surface - denoted with reference A - thereof.
  • the head unit 10 therefore comprises at least one inlet 11 port, in fluid communication with the inlet refrigerant fluid flow, which allows the latter to enter said head unit 10.
  • the head unit 10 is thus a hollow element, that is an element in which is defined a transit region 12 through which the inlet fluid flow passes towards the tube plate 100.
  • the inlet 11 in the head unit 10 are intended to be two, however, in other embodiments, said inlet can be different in numbers, for example one or four, depending on the operating modes of the exchanger in which the distributor assembly according to the present invention will be mounted.
  • the coupling surface A - also with reference to the shown examples - is a peripheral region of the head unit 10 and of the respective tube plate 100, shaped so as to flange the above-mentioned two elements together.
  • this peripheral region defines a circular crown, however, different coupling geometries are possible.
  • the tube plate 100 of a heat exchanger comprises a zone having a plurality of apertures - or housings 101 - configured to put in fluid communication said head inlet 11 and tubes of the exchanger.
  • each aperture of said plurality is suitable for coupling with respective tubular elements (not shown in the figures) within which, in use, the refrigerant fluid flows.
  • the plurality of housings 101 - which in the examples are a plurality of through holes 101a of the plate 100 - are configured to allow the refrigerant fluid inletting the head unit 10 passing towards tubular elements which typically engage with their terminal end the plate 100 at said housings, and which form the tube bundle housed within the exchanger's casing.
  • housings 101 are obtained only on a portion of the plate 100, particularly on the portion corresponding to one of the two inlet 11 of the head unit 10.
  • the distributor assembly 1 can be coupled with a tube plate 100 having a housings distribution different from that one illustrated.
  • the head unit 10 is further provided with a seat 13 adapted to receive a lamination unit 20, in particular of a plate-shaped geometry, which lamination unit 20 is positioned in said seat 13 so as to divide the transit region 12 of the head unit 10 in a first collecting chamber 14 and in an outlet region 15 of the refrigerant fluid.
  • the plate-shaped lamination unit 20 comprises an inlet surface 21, an outlet surface 22 and one or more openings 23 to allow the fluid entering the head unit 10 to pass there through.
  • the first collecting chamber 14 is comprised between the inlet 11 adapted to receive the fluid entering the head unit 10 and said inlet surface 21.

  • the refrigerant fluid flow F entering the inlet 11 of the head unit 10 reaches the lamination unit 20 and crosses said one or more openings 23 of the latter being subjected to a pressure drop causing it to expand into the second mixing chamber 30 and to generate a turbulent flow regime.
  • mixing chamber 30 permits to improve the refrigerant fluid flow F' conditions before its inlet into the exchanger tube bundle, namely achieving a uniform mixing of the latter entering the through holes 101a of the tube plate 100.
  • the lamination unit 20 is locked to the seat 13 of the head unit 10 onto shoulders 13a thereof. It is preferably fixed to the latter in a removable manner, by means of fastening means known to the skilled person in the field.

  • the first portion is internally hollow and configured to engage a through hole 101a of the tube plate 100 and the second portion remains outside of the tube plate in such a way as to maintain the lamination unit in abutment onto said shoulders 13a of the head unit 10, spaced from the tube plate 100.
  • More than one spacer can be provided, the number of which is function of the operative condition of the distributor.
  • said spacers are provided in a homogeneous chessboard-like distribution.
