Definitions

  • HEAT EXCHANGER UNIT ABSTRACT large transverse parallel plate finned heat 4 cum. 3 Dumb Figs exchanger section 18 constructed with a pluralltv of transverse horizontal spaced rows of vertically aligned fluid-conducting [52] US. Cl i 165/182 tubes of flat cross section soldered to the Parana] plates to 7 F285 1/30 form a bracing bar construction which will permit the [50] Field of Search 165I166(Cur.), exchange,- to be readily cut m a number f Small units along a vertical plane extending through the center of the flat tubes in a given row.
  • Rem-cums Cited vertical rows extending through the parallel plates can also be' UNITED STATESPATENTS used independently of the fluid-conducting tubes extending 1,823,993 9/1931 Stanford 165/ 182X therethrough to permit cutting of sections in a vertical plane 2, 3/1939 You!!! l 32X along these pieces without disturbing the fluid-carrying tubes.
  • the present invention seeks to improve the heat exchanger constructionin such a way that small units can be severed from a largerheat'exchanger block efficiently and economically without damage to the units severed.
  • aheat exchanger block unit comprising on one hand a plurality of thin-walled tubes of flat cross section which are arranged in rows and parallel to each other for the passage of the heat carrier, and on the other hand n lurality of parallel plates or tins soldered to said tubes and noting its air baffles; smaller units are formed by severing the heat exchanger block into a smaller unit width.
  • Heat exchanger units of the type indicated are used mainly in the construction of vehicles orfor stationary use as coolers.
  • FIG. 1 shows horizontally extending flat tubes Lofa heat exchangerunit form vertical and horizontal rows and are m adefof tinned brass, and the outside cross section has a width of 2 millimeters and a height of 12 millimeters.
  • the wallthickness is .25 millimeters, and the horizontal distance from tube center to tube center is millimeters.
  • the tubes 1 are ,fixedwith respect to each other by the fins 2 .rnounted thereon and serving as air-conducting baffles.
  • the fins 2 are, of .l millimeter thickness, are closely spaced and are made of leaded sheet iron.
  • tube half portions 1a of a verticalrow of tubes In the planes of the vertical longitudinal sidefaces 3 and 4, of the unit are arranged tube half portions 1a of a verticalrow of tubes (only the face3 is visible).
  • the tube halves 1a are made by joining tubes 1 and baffl'es 2 to form a block not. shown) of multiple unit width, then are soldered to each other and subsequently cut up into units of the desired size.
  • the saw cuts are passed through the middle of vertical tube rows. Due to the flat tube cross section and a correspondingly measured width of cut, there result the flat end or terminal strips in which thus are countersunk in recesses provided in the fin edges.
  • These strips 1a stabilize or brace the longitudinal side faces 3, 4 or respectively the edges of the baffles 2 which form said faces. Such stabilizing or bracing is effective during the process of separation and later on against mechanical stresses.
  • the end faces of the unit are formed by end plates 5 of which only one is visible in the drawing.
  • the longitudinal sides of the heat exchanger unit can also be stabilized by means of flat bars extending parallel to the tubes, countersunk in recesses of the, cross leaf edges and soldered to the cross leaves as shown in H0. 3.
  • stabilizing bars are bend during the severing operation which can proceed at high speed.
  • a further advantage is that the longitudinal sidefaces produced by severing a block into several units, are stabilized at once by the halves of said bars, Le. the mutual distances of the separating edges of the cross leaves are defined on the half portions of the stabilizing bars and protected from being bent due to mechanical influences, which is highly important for stocking, for transport and even in the mounted condition of the elements.
  • the invention is very significant for the use of 'heat exchanger unit as room-heating radiator. Although units of different widths are required for different building projects,
  • a heat exchanger unit comprising:
  • each of said bracing elements comprising approximately one-half of a longitudinal vertical section of said conducting tubes.
  • a heat exchanger unit comprising:
  • bracing elements in said recesses and rigidly secured to said heat exchanger fins, and each of said bracing elements comprising approximately one-half of a longitudinal vertical section ofa solid bar.
