Definitions

  • ABSTRACT OF DISCLOSURE An easily transportable and demountable heat transfer apparatus combination in which a low pressure fluid stream is directed across a braided array of flexible plastic tubes mounted transversely of a substantially unpressurized fluid conduit the transverse cross section of which corresponds to the dimensions of the braided array so that the action of the fluid stream causes uniform distribution of the flexible tubes across the conduit and causes cooperation of the tubes with the conduit walls to substantially eliminate bypassing and localized compaction of tubes.
  • This invention relates to the field of heat transfer or heat exchange, and more specifically to heat transfer apparatus combinations of the cross flow type utilizing flexible plastic tube elements mounted in substantially unpressurized casing members.
  • FIG. 1 is a partial general perspective view of one version of a heat transfer apparatus embodying features of the present invention, parts of the structure have been broken away and other parts shown displaced somewhat from their normal positions for a clearer showing.
  • FIG. 2 is an enlarged view of a portion of an apparatus similar to that shown in FIG. 1 illustrating a preferred arrangement for connecting the fluid supply means to the tubular elements of the bundle and illustrating the balfle means cooperating with the end portions of the bundle to limit fluid bypassing of the bundle at the end portions. Also illustrated is a preferred construction of the casing member which defines the main fluid passageway in which the bundles are positioned.
  • FIG. 3 is a partial enlarged exploded view showing a quick-disconnect fastener and a resiliently flexible selfsealing washer which cooperate with one end of a tie-rod member of the type which are used to secure the parts of the housing in operative position.
  • FIG. 1 An improved heat transfer apparatus embodying features of the invention is shown in FIG. 1 and comprises a box-like housing assembly formed by assembling opposed rectangular side elements 11, opposed end elements 10, corner elements 12 and side braces 20, all of suitable material such as for example, redwood for the side and end elements and metal for the corner or angle elements 12. Corner elements 12 and side braces 20 are fastened to side elements and end elements 12 by suittable fastening means 21, such as for example screws. The assembled elements are held together with a plurality of tie-rods or tie-bolts 17 having enlarged heads (not shown) at one end, and quickly disconnectable devices at the other end as generally shown in FIG. 3.
  • the boxlike housing assembly is provided with bottom corner elements 13 and legs or support elements L to maintain it in the preferred upright position, and a planar bottom element 14 formed of a suitable material such as for example redwood.
  • the housing assembly is further provided with a similar planar element 15 spaced from and parallel to bottom element 14 and secured by vertical tie-rod elements 17' and compressional support elements 16 in position as shown to form a chamber DC at the bottom of the housing assembly.
  • planar element 15 is also supported at its edge portions in closefitting grooves or recesses 59 formed in the side and end elements 10 and 11.
  • An inlet is provided in one of the lower end elements 10 to provide for supplying a fluid stream FS into the chamber DC as shown by the arrow in the lower left-hand corner of FIG. 1.
  • Each vertical manifold member is provided with a corresponding set of fittings 45, 46, 45', 46' between which are operatively connected bundles 47 of small diameter, thin-walled flexible tubular elements T as shown generally in FIG. 1.
  • FIG. 2 shows in more detail a somewhat ditferent preferred arrangement for connecting the bundles 47 to the appropriate fittings on the manifold members.
  • the bundle 47 is preferably in the form of a flat braided array which is closely fitted between opposing side elements 11.
  • the flexible tubular elements T of the bundle 47 are brought together at the ends of the bundles and bonded to each other and to an annular unit 75, the tubular elements T and unit 75 are preferably formed of a solid polymeric material, while the manifold members 40, 40', 40A (FIG. 2) are preferably formed of a suitable metallic composition such as stainless steel or cast iron.
  • the plastic units 75 are received in an annular sleeve element 73 of suitable material such as a metal.
  • Annular sleeve element 73 is radially spaced from the outer periphery of annular unit 75 to allow for thermal expansion of unit 75 at all desired operating conditions.
  • Element 73 is axially coextensive with unit 75 and both are clamped or secured between flange 70 of manifold member 40A and a flat annular ring element 71 by means of bolts 74. Ring element 71 is secured by bolts 72 to an interior cross wall element 60 which will be described at a later point in this specification.
  • An end face of the annular unit 75 is provided with a resilient sealing ring 76 positioned in an annular end groove as shown, in order to prevent leakage of a fluid passing from the manifold member 40A into and through the tubular elements T of the bundle 47. ISuflicient clearance is provided between the end face of unit 75 and the opposed flange 70 of the manifold member 40A to permit axial thermal expansion of unit 75 without detrimental contact between these parts or overstressing of the sealing ring 76.
  • the bundles 47 of flexible tubular elements are, as mentioned above, arranged in a braided configuration, preferably in a flat braided array. It is believed that any form of interlacing, braiding, or interweaving will be satisfactory so long as substantial overall uniformity is achieved with respect to its effects on fluid flow and tubular element packing. Bundles formed on braided sleevelike arrays, one inside the other, for example, have been found to perform satisfactorily.
  • Formation of the braided or interwoven bundles can be suitably accomplished on conventional well-known braiding machinery with a few minor modifications obviously necessary to convert them from operation with small solid wires or yarns to operation with the small flexible tubular elements utilized in the apparatus of this invention.
  • One example of a satisfactory arrangement for forming the interlaced bundles utilized in the apparatus of this invention is disclosed in Catalog 56 (ELF-20004- 1M11-64) on Braiders of the New England Butt Co., 304 Pearl St., Buffalo, R.I.
  • each bundle comprises a portion having a first plurality of tubular elements positioned in a first pattern and an interengaged, interlaced second plurality of tubular elements positioned in a second somewhat opposed pattern. It has been found that if the tubular elements are interwoven or braided together too tightly, a substantially closed pattern with prohibitive resistance to fluid flow, unacceptable susceptability to plugging, and undesirable kinking or distortion of individual tubular elements is formed. On the other hand, if the tubular elements are interwoven or braided too loosely, the bundle loses its desired coherence and compactness; also, the position of the elements relative to each other to maintain a desired uniform packing and resistance to fluid flow through the bundle cannot be established or maintained.
  • an inner transverse vertical wall is formed a short distance from each of the end walls and substantially parallel thereto to form end chambers which enclose the manifold members 40, 40'.
  • these inner transverse walls extend between the opposed side elements 11 and are formed by eorresponding abutting wall elements 22A and 22B which extend inwardly from the side wall elements 11.
  • Wall elements 22A and 22B are provided with cut out portions which engage and fit around the end portions of bundles 47.
  • the lower end elements are provided with openings or passageways O which provide free communication between the end chambers and space outside the overall casing assembly.

  • the transverse dimensions of this passageway correspond closely with the transverse dimensions of the central major portions of the bundles 47. It will be seen in FIG. 1 that the uppermost wall elements 22A, 22B terminate at a point lower than the cooperating side elements 11.
  • the central portion of the element 15, between the inner walls formed by elements 22A and 22B, is provided with an evenly distributed plurality of openings or small passageways 31 to provide free communication between chamber DC and the fluid passageway defined between opposed side elements 11 and opposed walls formed by elements 22A and 22B, in which fluid passageway the bundles 47 are positioned as shown.
  • baflle elements 52 which may be formed of any suitable material such as a cellular or foamed plastic composition.
  • baffle elements 52 are resilient and shaped as indicated in FIG. 1 to yieldingly engage the end portions of bundles 47, the wall elements 22A, 22B, and opposed side wall elements 11 to prevent fluid moving through the passageway in which the bundles are positioned from by-passing and channeling past the major portions of the bundles.
  • a top cover element 23 is provided to provide general protection for the plastic tubular elements of the bundles against debris and falling objects.
  • the housing assembly is constructed so that the end elements and side elements of one side of the apparatus can be removed as one sub assembly by suitable means such as a chain hoist or a light duty crane.
  • Lifting rings 19 are provided to assist in this removal or disassembly which, as shown, makes the entire interior and internal components of the apparatus readily accessible for inspection, testing, repair or removal of other components such as bundles 47.
  • the version of the apparatus shown in FIG. 1 is adapted to be used in an upright position as shown, being supported on legs or support elements L over an open drainage ditch or grating for conducting away one of the fluids used in the heat exchange operation.
  • One fluid supply conduit (not shown) is adapted to be operatively connected with inlet 30 at the end of the housing assembly and chamber DC.
  • Another fluid is supplied to the upper end 44 of manifold member 40 through a suitable connection, and removed from the upper end 44' of the other manifold member 40' after passing through the interiors of the tubular elements T of bundles 47.
  • the operation of the apparatus is believed to be clear.
  • the hot fluid to be cooled such as for example hot sulfuric acid is passed through the interior of the tubular elements T of the bundles 47 while the low pressure cooling fluid such as water is passed through the housing assembly as described above, entering distribution chamber DC through inlet 30, passing through openings 31 in element 15 and upwardly in full cross flow across the bundles 47, where most of the heat transfer occurs, and downwardly at each end through the end chambers surrounding the header members 40, 40', exiting through openings 0 to a suitable drain or disposal means.
  • Some heat is transferred between the fluid inside the header members and the fluid moving in the end chambers outside of the header members.
  • FIG. 2 The general arrangement and functioning of parts shown in FIG. 2 are essentially the same as the FIG. 1 embodiment, there being a different fluid connection unit acting betweenthe header 40A and the bundle 47, a somewhat different form of header members, a different form of battle element 52A which is held in position against the sides of the bundle end portions between opposed brackets 52B which are secured in position to the side wall elements 11, a somewhat different but equivalent means of assembling the various side, end and bottom elements, and a different inner wall structure which forms the end chamber enclosing the header member.
  • the inner wall which forms the end chamber comprises wall elements 60 each having the opening 61 formed therein to receive an end portion of the bundle 47.
  • Elements 60 as well as elements 15 are maintained in position by angle elements 12' which are secured to the side elements 11 by any suitable means.
  • a resilient tubular sealing element M is positioned as shown in cooperation with the side wall element 11, the angle elements 12, and the edge of wall element 60 to maintain a suitable sealing arrangement.
  • Reference numeral 62 indicates a limit stop element which is one of a number adapted to limit the downward movement of bundle 47 and support the bundle when the fluid stream is not moving through the housing assembly outside of the tubular elements of the bundle.
  • the rod 63 is shown mounted in a vertically extending slot 64 to permit selective positioning of the rod as it acts to limit the upward movement of the bundle 47 during upward flow of fluid across the bundle and maintain the other parts of the housing casing assembly in operative position.
  • FIG. 3 illustrates generally one preferred version of a conventional quickly disconnecta'ble device for securing the tie-rods or tie-bolts 63 and 17 in position.
  • the end of the tie-rod is provided with a recess or groove 90, a flexible bowed disc element 91 having a central depression 92 in which is formed an opening to receive the end of rod 17, is held against the side element 11 by engagement of a cam portion 93 of an actuating element 94 with the depression 92, the pivot pin 95 of element 94 being rotatably received in the recess in the end of the rod.
  • the end of a tie-rod with the recess 90 is positioned to extend through one of the openings 18 in the elements forming the casing assembly as shown in FIG. 3, the disc element 91 is placed against the side element 11 with the rod extending through its central orifice, then the pivot pin is positioned in the recess 90 with the actuating element 94 aligned generally as shown in this figure, and the actuating element is rotated about the pivot pin 95 to bring cam portion 93 into engagement with the recess in the disc and tension the tie-rod to to secure side element 11 in position.
  • the fluid stream moving across the bundles is evenly distributed over its transverse crosssection by the openings 31 which communicate with distribution chamber DC.
  • the flexible interwoven array of tubular elements of each bundle 47 under action of this fluid stream, distributes itself uniformly across this passageway in a open low resistance pattern which cooperates with the side elements defining the passageway to substantially eliminate by-passing over the major portion of the bundles and localized compaction of the tube elements, thereby avoiding dead or stagnant flow conditions and minimizing the risk of plugging due to foreign matter in this stream.
  • Elements 52A and 52 prevent the fluid stream from bypassing the bundle at the ends of the bundles 47.
  • Causing the fluid stream to move through the end chambers surrounding the manifold members makes possible additional heat transfer and controls the temperature of the manifold members and connections to the bundles which possess cooperating parts of plastic and metal as described above. Controlling the temperature of these connections is done in a way to minimize relative movement and generation of undesirable forces due to the diflerent coeflicients of thermal expansion of these parts.
