  • the said end plate means are provided with interengaging locating means for assisting assembling them together during formation of said end plate assembly.
  • the assembling together of the said end plate means and the permanent uniting together of the end plate means and of the end portions of the U-shaped tubes to the inner plate means are performed automatically, e.g. with robots.
  • the permanent uniting/fixing is performed by adhesive bonding.
  • the inner end plate means conveniently has recesses formed about each of said apertures, into which recesses adhesive is applied for bonding the said portions of the U-shaped tubes adjacent said free ends to the said inner plate means.
  • the adhesive typically­ly comprises heat curable adhesive, e.g. an epoxy resin, the heat exchanger being heated in an oven device to effect said heat curing.
  • heat curable adhesive e.g. an epoxy resin
  • the heat exchanger is tested for leaks in the said flow channels.
  • FIGS 1 to 10 show various parts of an evaporator 1 for a motor vehicle air conditioning system.
  • the evapor­ator 1 includes a plurality of metallic U-shaped tubes 3, typically made of aluminium or copper, each having free ends 3 a , 3 b which project through apertures 4 of an inner end plate 6, and a plurality of heat conductive fins 5, e.g. of aluminium, thermally connected to the U-shaped tubes.
  • the inner end plate 6 forms part of an end plate assembly comprising the inner end plate 6, an outer end plate 7 and, intermediate the inner and outer end plates 6 and 7, a first intermediate end plate 8 and a second intermediate end plate 9.

  • the end plates 6-9 of the end plate assembly are each provided with recesses, slots and/or passages as shown in Figures 1 to 10. These various recesses, slots and pas­sages communicate with each other in the completed end plate assembly to define:
  • Inlet and outlet tubes 30 and 31, respectively, are adhesively bonded to the outer end plate 7 to place the inlet tube 30 in communication with the distribution chamber 13 and the outlet tube 31 in communication with the collection chamber 21.
  • refrigerant is supplied via the inlet tube 30 to the distribution chamber 13 from where it passes to the flow inlets 11 via the inlet flow control channels 15 - 19.
  • the refrigerant then passes through the different fluid flow channels provided by the various interconnected U-shaped tubes 3 and is eventually collected in the collection chamber 21 before exiting via the outlet tube 31.
  • the temperatures of the refrigerant exiting the flow outlets 12 of the fluid flow channels should be substantially the same.
  • the amount of refrigerant supplied to the flow inlets 11 is dependent on the relative lengths and dimensions of the various inlet flow control channels 15 - 19 and in particular the first channel portions 15 a - 19 a thereof.
  • the different lengths of the channel portions 15 a - 19 a is to provide, in use of the evaporator, equal and/or consistent distribution or refrig­erant to the flow inlets 11.
  • the purpose of the second channel portions 15 b - 19 b is to ensure that the refriger­ant expands gradually when passing from the narrow first channel portions 15 a - 19 a to the wider flow inlets 11. This serves to ensure that the expansion occurs as silently as possible - i.e. without an accompanying generation of sound as the refrigerant passes into the fluid flow chan­nels provided by the U-shaped tubes 3.
  • FIG. 11 A process for automatically assembling the end plate assembly of the evaporator is shown schematically in Figure 11.
  • Partly formed evaporators 50, with the free ends of the tubes 3 projecting through the inner end plate 6, are passed through a warming oven 51 to warm the partly formed evaporators to a predetermined temperature, e.g. approxi­mately 30°C for the presently preferred adhesive.
  • the evaporator 50 is accurate­ly located and clamped at a first adhesive applying station 52.
  • heat curable adhesive e.g.
  • epoxy resin from a reservoir 53 is applied via an automatic programmable XY adhesive dispenser 54, movable in two dimensions, to the inner end plate 6 to flood the inner plate with adhesive around each tube end 3 a , 3 b .
  • the plate 6 is provided with elongate recesses 55 around pairs of holes 56 through which the ends 3 a , 3 b of different tubes project, with annular recesses 40 about holes 41 through which project the tube end 3 a defining the fluid inlets 11 and with annular recesses 42 about holes 43 through which project the tube ends 3 b defining the fluid outlets 12. It is there reces­ses 55, 40 and 42 into which the dispenser 54 floods the adhesives.
  • the adhesive reservoir 53 is heated to ensure that the adhesive is dispensed at a predetermined tempera­ture, e.g. 30°C.
  • the evaporator 50 is then moved to a second adhesive applying station 57 where it is accurately located and clamped.
  • An automatic programmable XYZ adhesive dispenser 58 movable in three dimensions dispenses beads of adhesive from the reservoir 53 over the inner end plate in a prede­termined pattern.
  • a 4-axis robot 59 then picks up the second intermediate end plate 9 from a support surface 60 heated to a predetermined temperature, e.g. 30°C, and places the plate 9 on top of the inner end plate 6.
  • Adhesive from the reservoir 53 is again applied in bead form via the dispenser 58 to the partially formed end plate assembly but this time to the second intermediate end plate 9.
  • the robot 59 picks up the first intermediate end plate 8 from the support 60 and places in on top of the second intermediate end plate 9.
  • the dispenser 58 then applies beads of adhesives to the first intermediate end plate 8 and the robot 59 picks up the outer end plate 7 from the support 60 and places it on top of the first intermediate end plate 8.
  • the robot 59 then picks up each of the inlet and outlet tubes 30 and 31 in turn and places them, correctly orientated, in inlet and outlet holes 61 and 62, respec­tively, formed in the outer end plate 7.
  • the dispenser 58 then applied adhesive into a raised elongate trough 63 formed in the plate 7 and which surrounds the inlet and outlet holes 61 and 62.
  • the location of the inlet and outlet tubes in the holes 61 and 62 requires the robot 59 to have a special gripper (not shown).
  • the location of, and application of adhesive to, the inlet and outlet tubes 30 and 31 may alternatively be performed manually at a separate station (not shown).
  • the evaporator assembly is then loaded into a curing oven (not shown) for a predetermined period of time, e.g. 15 minutes, to allow the applied adhesive to heat cure.
  • a predetermined period of time e.g. 15 minutes
  • a number e.g. about 20, of evaporator assemblies will be placed together in a batch in the curing oven for curing in any one curing operation.
  • each evaporator is tested for leaks using a helium mass spectrometer. Any rejected evaporators are returned for re-sealing - e.g. by the application of further adhesive around the periphery of a plate interface.
  • the end plates may be provided with interengaging locating means (not shown), e.g. studs and recesses, to assist in their accurate placement on top of each other by the robot 59.
  • interengaging locating means e.g. studs and recesses
  • the evaporator assemblies are suitably automatically transported from station to station on simple support platens operating on a "power and free" principle allowing platens to accumulate before a work station and be rapidly indexed in and out of the work station to maximise process time. After each evaporator assembly is manually off-­loaded from the support platen on to an oven jig trolley, the empty support platen is returned to the load station on an automatic transfer device.
  • the evaporator assembly, end plates 6 - 9, adhesive and inlet and outlet tubes 30, 31 are preferably all pre-­heated and predetermined temperatures so that the process can be accurately reproduced whatever the temperature of the premises in which the manufacturing process occurs.
  • Figure 12 shows an end plate assembly comprising an inner end plate 70, an outer end plate 71 and an inter­mediate end plate 72.
  • the inner end plate 70 is provided with a plurality of apertures 73 through which project the free ends 3 a , 3 b of the U-shaped tubes 3.
  • the intermediate plate 72 is of contoured form and defines connection channels 74 for connecting together pairs of tube ends 3 a , 3 b of different U-shaped tubes.
  • the inner end plate 70 is designed to be flooded with adhesive 75 to adhesively bond both the free ends 3 a , 3 b and the intermediate end plate 72 to the inner end plate 70.
  • the intermediate end plate 72 is of corrugated form and has crests 76 which define the connection channels 74 and trough 77 between the crests 76.
  • the other end plate 71 is adhesively bonded to the inter­mediate end plate in such a manner as to provide channels 78 between the base of the troughs 77 and the overlying end plate 71.
  • These channels 78 are designed to provide flow channels for distributing refrigerant to, and collecting refrigerant from, the flow channels formed by the intercon­nected U-shaped tubes 3.
  • Figure 13 is similar to the end plate assembly shown in Figure 12 with the exception that a further intermediate end plate 80 is provided to improve the curved shape of the connection channels 74.
  • the plate 80 need not be bonded in position since in use it will automatically adopt its correct position.
  • FIG. 14-17 A further embodiment of the invention is shown in Figures 14-17.
  • the end plate assembly is the same as that shown in Figures 1-10 with the excep­tion of the new design of the first intermediate end plate 108 (the same reference numbers + 100 have been used to designate similar parts).
  • the distribution chamber 113 is slightly longer than chamber 13, and the first channel portions 115 a - 119 a of the inlet flow control channels 115-119 are straight and of the same length.
  • the downstream section channel portions 115 b - 119 b incorporate expansion orifices 300, each in the form of a venturi-like passage. The provision of these expansion orifices 300 improves the efficiency of the evaporator since the refrigerant is not expanded until just before entering the U-shaped tubes 113 and dispenses with the need to connect a separate expansion valve to the inlet tube 130.
  • a modified end plate 208 is shown in Figures 18 and 19 in which the distribution chamber 213 and collection chamber 221 have varying cross-sectional throughout their lengths and are separated from each other by a thin"wavy" boundary wall.
  • the "wavy nature of this boundary wall increases its length over a straight boundary wall and thus improves the heat transfer between the collection and distribution chambers.
  • the "hot” liquid (typically about 50°C) in the "inlet” distribution chamber 213 is cooled by the "cold” vapour in the "outlet” collection chamber 221, the thin, wavy boundary wall ensuring good heat transfer between the two chambers.
  • the good heat exchange between the chambers and the "sub-cooling" of the liquid in the distribution chamber thus provides an im­proved thermal efficiency.
  • the metallic end plates may be ultrasonically welded together.
  • the ends of the U-shaped tubes may also be ultrasonically welded to the end plate assemblies. In this manner each tube/end plate assembly is permanently united as an integral structure.
  • the tubes-­/end plates may be adhesively bonded together as previously described in the earlier embodiments.
  • the invention has been specifically described herein with reference to an evaporator of a vehicle air condition­ing system.
  • the invention can be applied to other types of heat exchanger of the kind referred to.
  • the invention could find application in a condensor of a vehicle air conditioning system.
  • higher temperatures and pressures are employed in condensors and the adhesive used must, of course, be capable of withstand­ing these higher temperatures and pressures.
