Definitions

  • the invention relates to a counterflow heat exchanger according to the preamble of claim 1.
  • a heat exchanger is known from DE-A-1 501 586, at which the plates in the area of the actual heat exchange sections can be waved sinusoidally.
  • the above Publication is a variety of different fluid channel cross sections suggested by different designed waves of the plates can be achieved.
  • the one over there proposed channel cross sections is common that the Transition between the flat cross section of each Plate and the corrugated cross section of the respective plate is provided abruptly.
  • EP-A-0 732 552 is a counterflow heat exchanger known of a package of stacked plates has spaces that form gaps between them. On their the gaps to the direction of flow of the two alternating and flowing essentially antiparallel Edges parallel to fluid flows are the countercurrent heat exchanger forming plates tightly together connected. Each plate has a corrugated cross section Wave valleys and wave crests, the wave valleys against the wave crests of the plate adjacent on one side and the wave crests against the wave valleys of the other Apply to the adjacent plate.
  • a counterflow heat exchanger the generic described above To create a type whose efficiency is further increased and in which a trouble-free entry of the fluid flows into the approximately circular fluid channels is guaranteed.
  • the counterflow heat exchanger - in Direction of flow or seen in flow directions - both at one end and at the other End each an inlet section and an outlet section form, with a fluid flow through the inlet portion one end and the outlet section at the other end and the other fluid flow through the inlet section at the the other end and the outlet section at one end to be led.
  • the counterflow heat exchanger according to the invention can be used a comparatively low design effort and with the smallest possible number of different components produce according to claim 7.
  • Counterflow heat exchanger according to claim 8 essentially from only two types of plates.
  • a in Figure 1 in cross section of its actual countercurrent section illustrated countercurrent heat exchanger according to the invention is made up of plates 1, one of which Type of construction is shown in Figure 2.
  • the plates 1 In their the actual counterflow section of the counterflow heat exchanger middle sections 2 the plates 1 have a sinusoidally corrugated cross section 3 on.
  • each plate 1 With the troughs 4 of the sinusoidally corrugated cross section 3 lies each plate 1 on the wave crests 5 of sinusoidal corrugated cross section on one side adjacent plate 1; the same applies to the wave crests 5 and the troughs 4 on the other side neighboring plate 1.
  • each fluid channel 7, which flows through the one fluid or gas stream A. is surrounded on all sides by fluid channels 7, which by flow through the other fluid stream B.
  • the Plates 1 bent at right angles on their long sides Edges 8, the dimensions of which are approximately twice the average Distance of the plates 1 corresponds to each other.
  • the Edges 8 can be the plates 1 by welding or connect the adhesive seal.
  • each plate has 1 the middle section 2, in which they are shown in Figure 1 has sinusoidally corrugated cross section 3; on that formed by the sinusoidally corrugated cross section 3 middle section or counterflow section 2 of the Plate 1 closes a transition section on both sides 9 or 10.
  • transition sections 9 and 10 goes the plate 1 from the sinusoidally corrugated cross section 3 to a flat cross section 11 about how best to look Figures 3, 4 and 8 results.
  • the inlet section 12 and the outlet section 13 taper triangular from the transition section 9 or 10.
  • One leg 14 or 15 of the triangular inlet section or outlet section has a sealing edge 16 and 17 respectively, which in the case of the inlet section 12 on the left side of one shown in Figure 9 Plate longitudinal center line 18 and in the case of the outlet section 13 on the right side of this longitudinal plate center line 18 is arranged.
  • the gas or fluid flow A, B occurs in the area of the sealing edge free Leg 19 of the inlet portion 12 in the Counterflow heat exchanger enters and occurs in the area of the sealing bend-free Leg 20 of the outlet section 13 on the counterflow heat exchanger.
  • support elements 21 are provided, which are parallel to the sealing edge 16 or 17 of the Extend inlet section 12 or outlet section 13, so that the support elements 21 at the same time as fluid guide elements serve and those passing through the inlet portion 12 Gas or fluid flow A, B in the transition section 9 deflect or exit from the transition section 10 Gas or fluid flow A, B to the leg free of sealing bends Deflect 20 of the outlet portion 13.
  • the support elements 21 correspond in terms of their dimensions in the thickness direction of the plate 1 the plate distance in Area of the two end sections of the countercurrent heat exchanger, so that they rest against the adjacent plate 1. This also results in the area of the two end sections of the counterflow heat exchanger even at strong different pressures of the two gas or fluid flows A, B sufficient stability.
  • the counterflow heat exchanger according to the invention consists of Plates 1 of the type shown in Figure 2 and from plates 1 of the type of construction partially shown in FIG. 9, in which the sealing edges 16 and 17 as well as the support elements 21 perpendicular to the sealing edges 16, 17 and support elements 21 of the type of construction shown in FIG.
  • the depth and number of wave valleys 4 and wave crests 5 of the sinusoidally corrugated cross section 3 in the middle or counterflow section 2 of the counterflow heat exchanger is arbitrary and according to the requirement profiles regarding the pressure loss and the heat recovery suitably selectable.
  • the counterflow heat exchanger according to the invention can be due to the thermodynamic favorable countercurrent flow achieve high heat recovery rates; due to the smooth, almost circular cross-sections of the Fluid channels 7 in the middle or counterflow section 2 the pressure loss is comparatively low, being above in addition, the effort for the removal of dirt or the like. for this reason is significantly reduced.
  • the individual plates 1 of the counterflow heat exchanger according to the invention support each other and a comparative rigid structure of the invention Form countercurrent heat exchanger, there is a Stability, even with large pressure differences between the two gas or fluid streams A, B is sufficient.
