Definitions

  • This invention relates to heat exchangers and, in particular, to heat exchangers having a plurality of parallel, spaced tubes for heat exchange fluid, the tubes being assembled into a unit using a tube plate having holes for receiving the tubes, and the plate extending transverse to the axes of the tubes.
  • An object of the invention is to provide an improved tube to tube plate assembly.
  • a heat exchanger comprises parallel, spaced tubes, a tube plate apertured to receive the tubes and extending transverse to the axes of the tubes, and a supplementary plate apertured to receive at least one of the tubes, the supplementary plate having over a peripheral region a portion extending transversely of the plane of the plate and secured to the tube plate whereby the supplementary plate is spaced from and parallel to the tube plate and fits over the associated tube or tubes to reinforce the tube and tube plate connection.
  • the peripheral region of the supplementary plate includes a flange portion which lies parallel to the tube plate and is secured thereto by, for example, welding.
  • the apertures in the tube plate and in the supplementary plate are each conveniently formed with upstanding rims which project from the plates in the same direction as one another.
  • the depths of the rims are preferably arranged to be less than the spacing between the tube plate and the supplementary plate.
  • the supplementary plate is conveniently of generally rectangular shape in plan view and the peripheral region extends over one or more edges of the plate.
  • a heat exchanger which consists of a header tank 10 defined by a header member 11 (only part of which is shown) and a tube plate 12 secured thereto by bolts 13 and including a gasket 14.
  • Tubes 15 communicate with the tank space 10 and lie parallel to one another and at right angles to the tube plate 12.
  • the tubes 15 are in this case of flattened elongate form.
  • the tubes 15 pass through secondary heat exchange surfaces in the form of fins 16, in known manner.
  • the tube plate 12 is formed with a plurality of apertures through which the tubes 15 pass to enter into the space 10 and it is arranged that a fluid passes along the tubes between the header tank 10 at the upper ends of the tubes and a further tank (not shown) at the opposite, lower ends of the tubes. A further fluid with which heat is to be exchanged passes over the fins 16 and over the exterior of the tubes 15.
  • the apertures in the tube plate 12 are formed in a manner, for example by plunging, such that an upstanding lip is defined around each of the apertures.
  • the connection between the tubes 15 and tube plate 12 comes under stress, particularly towards the outermost tubes, i.e. the tubes closest to the outer edges of the header tank. This is believed to be due, a ⁇ least in part, to the tube plate 12 acting as a diaphragm as the tubes expand and contract.
  • the reinforcing plate 20 is arranged to define apertures for receiving the outermost rows of tubes 15 in certain regions of the array of tubes and, over the apertured area of the plate 20, the plate 20 is parallel to and spaced from the tube plate 12.
  • the apertures in the plate 20 are formed in a similar manner to those in the tube plate 12 so that an upstanding lip is defined around each aperture, the lips being directed upwards and in the same direction as those of the tube plate 12.
  • the plate 20 is secured to the tube plate 12 along at least one of its peripheral edges by forming the edge with a transversely-directed bend 21 and a flange 22.
  • the flange 22 lies in contact with the tube plate 12 and is secured thereto by welding, preferably by spot welding at spaced positions longitudinally of the flange.
  • a turned-over portion 23 has its free end closely adjacent the surface of the tube plate 12.
  • Figs. 2 and 3 shows a specific form of tube plate 12', tubes 15' and reinforcing plates 20A' and 20B'.
  • lateral rows P of tubes 15' lie at right angles to the sides of a rectangular tube plate 12'.
  • the tubes 15' also lie in longitudinal rows R lying parallel to said sides, and at opposite ends of the rows R are arranged the reinforcing plates 20A' and 20B'.
  • Fig. 2 only one end of the assembly is shown.
  • the plates 20A I and 20B I take similar forms and each receive six of the rows P of tubes 15' through apertures aligned with apertures in the tube plate 12'.
  • the plates 20A' and 20B I together receive all the tubes across the longitudinal rows R over said six lateral rows P.
  • Each plate 20A' and 20B' is of generally rectangular shape and has a transverse bend 21' and flange 22' along two of its peripheral edges, the flanges 22' being secured to the tube plate 12' by welding as described in relation to Fig. 1.
  • the plates each have a turned over portion 23' along another peripheral edge, the portions 23' lying closely adjacent one another.
  • Figs. 4, 5 and 6 show a reinforcing plate 20'of Figs. 2 and 3 as a separate element before assembly with the tube plate 12'.
  • connection of the tubes to the tube plate and to the reinforcing plate are enhanced by soldering, for example by dipping the assembled unit into solder.
  • the tube to tube plate connection may be reinforced with different configurations of reinforcing plate.
  • the reinforcement plate may receive all the tubes in an array.
  • each reinforcing plate 20' with one or more V-shaped grooves or corrugations, the apex of the V being in contact with the tube plate 12' when assembled.
  • Each corrugation extends between two or more of the rows P and serves to additionally reinforce and support the tube to tube plate connection.
