Definitions

  • HEAT EXCHANGERS HEAT EXCHANGERS, FEE-HEATER, ECONOMIZERS AND THE LIKE Filed July 19, 1963 2 Sheets-Sheet 2 United States Patent 3,232,344 HEAT EXCHANGERS, PRE-HEATERS, EQUNUMIZERS AND THE LIKE Erik Sven Alvar Andersson, Orrstigen l2, and Uno Sven Johnson, Jarpstigen 7, both of Sodertalje, Sweden Filed July 19, 1963, Ser. No. 296,312 Claims priority, application Sweden, July 20, 1962, 8,091/62 Ciaims. (Cl.
  • the present invention relates to heat-exchangers, preheaters, economizers and similar apparatus in which a heat-absorbing or heat-delivering medium flows through a space in which one or more heat transfer elements are disposed solidly secured to at least one wall defining said space.
  • a general object of the invention is to provide a heat transfer element of a design which is new in its context and which makes it possible to utilize said element also for the purpose of guiding, or controlling, the flow of said medium.
  • a special object of the invention is to provide a heat transfer element of such a shape that one branch of said medium flow can pass inside the element.
  • a further object of the invention is to provide a heat transfer element permitting great variations as to the proportion between that branch of the medium flow, which passes inside the element, and that branch, which passes outside.
  • a still further object of the invention is to provide a heat transfer element which on the one hand is cheap per se and, on the other, can in a rapid and cheap way be fixed to said wall, such as through automatic welding, so that the manufacture costs of the complete apparatus become compartively low.
  • FiGURE 1 shows a heat transfer element according to a first embodiment of the invention.
  • FIGURE 2 shows a heat transfer element according to a second embodiment of the invention.
  • FIGURES 3a and 3b illustrate two ditferent ways of mounting a heat transfer element according to FIGURE 2.
  • FIGURE 4 is a fragmentary, sectional, perspective view showing a portion of a heat exchanging apparatus provided with heat transfer elements according to FIGURE 1.
  • FIGURE 5 illustrates the mounting of a heat transfer element according to FIGURES 2 and 3.
  • Reference numeral 1 designates a wall defining a space in e.g., a pre-heater, an economizer or some similar heatexchanging apparatus through which space there flows a heat-absorbing or heat-delivering medium.
  • On said wall 1 there are mounted a number of heat transfer elements 2.
  • these elements are constituted by pipes provided with substantially opposed or transverse holes, or perforations 3, while, according to the embodiment illustrated in FIGURE 2, each heat transfer element is constituted by a wire helically wound to a tube-like body. It is normally assumed that a wall corresponding to wall 1 is in close contact with the heat transfer elements at the opposite side thereof as shown in FIGURES 4 and 5. However, for the sake of surveyability no such wall has been shown in FIGURES 1 and 2.
  • elements 2 have been allotted two functions, i.e. they serve on one hand as heat transfer elements and, on the other, as means for controlling the medium flow.
  • the heat transfer element shown in FIGURE 2 and consisting of a helically wound wire is, as appears from that figure, somewhat flattened towards its longitudinal axis. Especially if this flattening is comparatively great, so that the loop-like portions at each of the two longitudinal sides of the element, where the individual winding turns meet, have a substantially greater radius of curvature at the one side than at the opposite one, it is an essential advantage that the joint between the element and the one of the two walls, the effective surface of which is increased by the element, is located at that side of the element, where the loops have the smaller radius of curvature.
  • FIGURE 5 in which element 2 accordingly is fixed to wall 1, e.g. through welding.
  • FIGURE 4 shows a portion of an apparatus, eg a heat-exchanging, in which the heat-delivering medium flows inside the element 2 whereas the heat-absorbing medium passes inside the big tube 1.
  • the winding turns of the wire may be located in planes which are either substantially axial or radial with respect to the co-axial tubes.
  • An apparatus for facilitating heat exchange between two fluids comprising:
  • said helical pipe having formed therein a plurality of substantially opposed perforations at spaced intervals along its length, whereby said helical pipe is adapted to carry a second fluid along a helical path through said helical pipe and along a second path, through said perforations, essentially parallel to the axes of said first and second tubes.
