Definitions

  • the invention relates to a method of forming a heat exchanger manifold, particularly, but not exclusively, a method of extruding features on a sheet of base material and folding the sheet of base material into a manifold for a Heating Ventilation and Conditioning (HVAC) system.
  • HVAC Heating Ventilation and Conditioning
  • heat exchanger manifolds prefferably have two longitudinal chambers; an inlet chamber for the flow of fluid into the manifold and an outlet chamber for the flow of fluid out of the manifold.
  • a method of forming a heat exchanger manifold from a sheet of base material comprising:
  • thermoelectric manifold formed from a sheet of base material, the heat exchanger manifold comprising:
  • the heat exchanger manifold in its initial unfolded configuration, comprises a sheet of base material 12 that is easily manipulated into the finished article and is suitably strong to withstand the environments it will be subjected to in use.
  • a suitable material is a sheet of aluminium alloy.
  • the sheet 12 is divided into first and second partition wall portions 14, first and second upper manifold wall portions 16, first and second side wall portions 18 and central portion 20. Division of the sheet may be assisted by the provision of discontinuities, such as score lines, formed in the surface of the sheet 12.
  • Opposed edges 22 have a series of short protrusions 24 and elongated protrusions 26 formed thereon.
  • the protrusions 24 and 26 combine to form ridged edges 22.
  • First and second partition wall portions 14 are each provided with fluid flow tube apertures 28 stamped therethrough.
  • Side wall portion 18 is also provided with a corresponding fluid flow tube aperture 30 as well as tube aperture 32.
  • Strengthening ribs 34 are provided in the remaining space between the apertures 30 and 32 on side wall portion 18 and along the entire length of the opposing side wall portion 18.
  • the apertures 28 and 32 are formed to allow a fluid flow tube F to be inserted therein as described in more detail subsequently.
  • Central portion 20 of the sheet 12 is formed with a series of tube insertion slots 36.
  • the tube insertion slots have a pair of opposed ledges 38 which protrude from the base sheet 12 to form the slot 36 therebetween, in which heat exchanger tubes T may be received.
  • the opposed ledges 38 also define locating channels 40 ( Fig. 1 B) on the base sheet material 12 between the ledges.
  • the series of tube insertion slots 36 do not span across the entire width of the central portion 20; to the contrary, side lips 42 are provided along either edge of the central portion 20 between either edge of the slots 36 and the adjacent side wall portions 18.
  • a longitudinal locating groove 21 is also provided along central portion 20.
  • the longitudinal locating groove 21 has regularly spaced mounting holes 44 which are of a shape and size which corresponds with the combined shape and size of the regularly spaced elongated protrusions 26 of the ridged edges 22.
  • strengthening ridges 34 and the locating groove 21 all of the above features are formed by stamping through the sheet of base material 12 with a stamping tool. Furthermore, certain features may also be formed by an extrusion process; for example, the apertures 28 and 32 may have extruded collars 28C, 32C to facilitate a fluid tight connection with the fluid flow tubes F.
  • the strengthening ridges 34 and locating groove 21 are formed by partially extruding portions of the base sheet in order to form indentations in the material wall without cutting there through.
  • the partition wall portions 14, upper manifold wall portions 16 and the side wall portions 18 are sequentially folded toward the central portion 20 in order to form the manifold 10 shown in Figs. 2 - 8 (this folding sequence is best described subsequently in relation to a second embodiment of the invention, although substantially the same sequence applies to this first embodiment).
  • the interior of the manifold 10 is divided by the partition walls 14W into a first longitudinal chamber 46 and a second longitudinal chamber 48 (one being for fluid flow into the manifold and the other being fro fluid flow out of the manifold).
  • aperture 30 in side wall 18W and the pair of apertures 28 in the partition walls 14W align with one another to provide a passage through which a fluid flow tube F may pass through chamber 46 and directly into chamber 48.
  • the elongated protrusions 26 of each ridged edge 22 pass into the mounting holes 44.
  • the elongated protrusions 26 may also be provided with an angled point in order to facilitate insertion into the mounting holes 44.
  • the series of short protrusions 24 sit snugly in the groove 21 within the series of channels 40 and allow brazing along all sides thereof.
  • the side lips 42 along the edge of the slots 36 allow the side walls 18 to be bent up from the plane of the base sheet 12 until they are very close to the tubes T. Indeed, the tubes T may be brazed directly to the side walls 18W to improve the overall structural rigidity of the manifold.
  • the separating web along the seam 50 of the tube T can be brazed to the edges of the partition walls 14W to provide a structural bond as well as a fluid tight seal therebetween.
  • FIG. 9A to 9E A second embodiment of the invention is shown in Figs. 9A to 9E .
  • the second embodiment of the invention is substantially similar to the first and has substantially the same advantages, with the exception of the apertures 128 which are, in this second embodiment, oval shaped and provided on the upper manifold wall 116W rather than through the side manifold walls 118W.
  • first and second partition wall portions 114 are folded toward the central portion 120 at approximately 90 degrees from the plane of the sheet of material to form partition walls 114W.
  • first and second upper manifold wall portions 116 are folded toward the central portion 120 at approximately 90 degrees from the plane of the sheet of material to form first and second upper manifold walls 116W and hence the partially closed box depicted in Fig. 9C .
  • a third folding step the first and second side wall portions 118, along with the previously folded partition walls 114W and previously folded first and second upper manifold walls 116W, are folded toward the central portion 120 as depicted in Fig. 9D .
  • the short protrusions 124 are meshed into the groove 121 in the channels 140 between the opposed ledges 136.
  • the elongated protrusions 126 of each opposed ridged edge 22 are jointly inserted into the mounting holes 44 to secure the manifold 10 in its final closed configuration depicted by Fig. 9E .
  • the manifolds of the present invention provide first and second inlet / outlet chambers which have a series of single heat exchanger tube insertion slots for both chambers and which provide optimum brazing properties.
  • the invention also improves the heat distribution, reduce the part count and complexity of the manifold over previous arrangements and minimises the likelihood of fluid leaks.
