Definitions

  • This invention refers to heat exchangers of the spiral sheet metal type, i. e. heat exchangers having the heat transmitting surfaces made of one or more metal sheets'wound to spirals, and 5 forming walls of the channels for the flowing media between which heatis to, be exchanged.
  • the chief purpose of this invention is to render such apparatus more resistive to shocks and other stresses and strains, without increasing the quantity of material used and the weight of the apparatus.
  • the heat exchanger in accordance with this invention may be constructed with a smaller quantity of material and have a lesser weight than that of ordi- 17, nary apparatus. 5
  • Another purpose of this invention is to render it possible to reduce the thickness of the spiral metal sheets, without impairing the function of the apparatus and without reducing its resist- I ance to shocks and strains.
  • FIG. 1 is across section through an apparatus in accordance with this invention, taken on the 5 line I-I in Fig; 2.
  • Fig. 2 shows an axial section on the line II -II in Fig. 1.
  • Figs. 3. and 4 show details of axial sections through otherembodiments, in which both of the spiral metal sheets are corrugated.
  • the spiral heat exchanger has two spiral metal sheets I and 2, of which the sheet I is smooth, while the sheet 2 is corrugated in such manner that the corrugations extend in the peripheral direction of the spiral, i. e. their longitudinal direction is at right angles to the axis of the spiral.
  • the cold medium is supplied through the pipe 3 and is drawn oil through the pipe 4 after having passed through the spiral channel 8.
  • the hot medium enters through the pipe 5, flows through the channel I and is drawn off through the pipe 6.
  • Fig. 3 shows an embodiment in which the two metal sheets are both corrugated, their corrugations being displaced somewhat in relation to each other. It is easily seen from the figure that the surface of heat transmission per unit of volume is increased in this apparatus, as comstrains are very must increased, without'any increase in the weight of the apparatus, or theapparatusmay be builtof thinner sheet metal,
  • corrugated as used herein, I mean 'a surface having alternate ridges and grooves without limitation to their particular shape. While I have shown and described several more or less specific embodiments of my inveninvention is not to be limited thereby but is to be determined by the appended claims viewed in the light of the prior art.
  • spiral walls of sheet metal forming therebetween spiral channels for flow of the fluids in spiral paths, said spiral walls being corrugated, the corrugations extending substantially parallel to the direction or flow, all the corrugations being substantially uniform in shape and abutting against each other on both sides substantially along the entire length of their crests so that all said walls abut directly against each other.
