Definitions

  • the present invention has for its principal object the provision of a form of heat ex changer which will enable widely varying operating conditions to be met by a structure of standard form and dimensions. Further object is the provision of a form of heat exchanger which after being assembled may have its characteristics so altered that it may be rendered suitable for operating conditions other than those for which it was originally designed.
  • the object of the invention is the provision of apparatus in which a plurality of heat exchange tubes are placed in the confined path of a heat absorbing or rejecting fluid in such a manner that the free flow area for said fluid, and consequently its velocity, may be varied in any given passage.
  • a still further object of the invention is the accomplishment of the above objects by the use of heat exchange elements of a type wherein the free flow area past such elements through any given passage may be varied by the rotation ofsaid elements around their longitudinal axes.
  • FIG. 1a I have shown diagrammatically a passage 1, defined by walls 2, and adapted to convey absorbing or rejecting fluid in either of the directions indicated by the arrow in the figure.
  • a plurality of fluid carrying elements Located transversely of the flow of fluid through passage 1 are a plurality of fluid carrying elements, each of which comprises a plurality of individual pipes 3 which are joined at their ends to form single end portions 4, the latter being secured in suitable headers, connected by return bends.
  • A may be widely varied within the scope of the invention, but for purposes of illustration I have shown these elements arranged in horizontal rows, with the elements staggered with respect to each other vertically.
  • Fig. 1a I have shown the elements arranged with the individual pipes 3 set horizontally with respect to each other in the individual units, and it will be readily apparent from the figure that with this arrangement, the minimum free flow area is provided for the fluid passing these elements.
  • Fig. 1?) I have shown the same apparatus with the elements rotatedabout their longitudinal axis substantially 45' deg. from the position shown in Fig. 1a, and
  • Fig. 2 I have shown a section taken longitudinally of the elements, inwhich the passage 1 is defined by the side walls 2 and headers 80.
  • the flow of fluid through the passage 1 is at right angles to the plane of the paper, and in this instance the units are formed with single cylindrical ends 4 adapted to be rolled or otherwise suitably secured in the inner walls 5 of headers 30, the latter being provided with suitable handholes or cover plates 6.
  • the apparatus is not adapted to be changed readily after having been originally assembled, but-the invention enables 'an apparatus of this character and of a certain standard size to be adapted to various types of service, because of the various positions in which the elements may be initially set.
  • Fig. 3 I have shown the apparatus, in a section similar to Fig. 2, constructed in a form suitable for change or adjustment of the units after the apparatus as a whole has beenassembled.
  • the element ends 4 are provided at their ends w1th upset or other suitably formed rings 7, the latter being ground to form suitable seats, prefer- Header boxes 8 seat against rings 7 and are held in place by means of the studs 10, which pass through suitable bosses on the header boxes and are screwed into ears formed on the clamp rings 9 which seat against the opposite faces of rings 7.
  • headers receiving a large number of tubes such as headers 30 in Fig. 2, for if the a'd'ustable type of element is used between such eaders, it will be apparent that all of the elements joining any two headers must be of exactly the same finished overall length if tight joints are to be secured, and that an une ual expansion of elements between sucfi hea ers would tend to produce leaky joints. For these reasons, I prefer to use individual header boxes such as those shown at 8 in Fig. 3, at least at one end of the elements, as far as possible Where the adjustable type of element is used.
  • Apparatus ofthe character described comprising, in combination, means providing a passage for flow of a heat absorbing or re! jecting fluid, a plurality of rows of heat exchange elements disposed transversely of sald passage each of said elements comprising coaxial end sections of circular cross-section and an intermediate section comprising a pair of spaced parallel pipe portions connecting said end sections, the elements of the several rows being staggered with respect to the general line of fluid flow through the passage and fluid conveying members connected by said elements, said end sections being secured to said members in positions such that planes passing through the center lines of the pairs of pipe portions of the elements lie at an angle to said general line of fluid flow through the passage to provide less than the through the passage past the elements.
  • a passage adapted to convey a heat absorbing or rejecting fluid, of a plurality of hollow heat exchanging elements located in said passage and adapted to withstand internal pressure without distortion, said elements being formed entirely by Walls the opposite sides of which are exposed to different fluids, the form and arrangement of said elements being such that the free'flow area through said passage past said elements is varied by the changes in position of said elements efiected by rotation of the elements about their longitudinal axes, fluid conveying members connected by said elements, and releasable means for securing said elements to said members to permit rotation of the elements.
  • Apparatus of the character described comprising, in combination, means providing a passage for flow of a heat absorbing or rejecting fluid, a plurality ofheat exchange elements disposed transversely of said passage, each of said elements comprising co-axial end sections of circular cross-section and an intermediate section comprising a pair of spaced parallel pipe portions of circular cross-section connecting said end sections, and fluid conveying members connected by said elements, said end sections being secured to said members in positions such that planes passing through the center lines of the pairs of pipe portions of the elements lie at an angle
