Definitions

  • the invention relates to a countercurrent heat exchanger according to the preamble of claim 1.
  • Such a countercurrent heat exchanger is known from EP-A-0 844 454.
  • profile channels are provided in the rectangular shape, which influence the heat exchange between the gas streams thermodynamically favorable.
  • some support elements are provided, which ensure sufficient stability in superimposed plates in the region of the two end portions and also serve as guide elements for the gases.
  • Another countercurrent heat exchanger is known from JP 08 200972 A.
  • This heat exchanger also shows hexagonal profile plates, wherein the profile plates for the first air flow and the profile plates for the second air flow in the plate plane are rotated by 180 ° from each other and between each two profile plates, a release layer is arranged.
  • each profile plate has a rectangular shape.
  • the heat exchanger in turn has a total of a hexagonal shape, wherein the inlet and outlet of the same air flow in the longitudinal direction of the heat exchanger takes place on the same side.
  • a countercurrent heat exchanger with profile plates is also known.
  • the counterflow heat exchanger has an overall hexagonal structure, but the profile plates have a rectangular shape. Even with a heat exchanger described in GB 12 23 752, the profile plates are rectangular overall.
  • the object of the invention is thus seen to develop the countercurrent heat exchanger of the type mentioned in such a way that a good temperature compensation and good heat recovery is achieved.
  • the countercurrent heat exchanger according to the preamble of claim 1 is formed according to the characterizing part of this claim according to the invention.
  • the entire base surface is covered with the hexagonal profile plates, so that seen over the entire longitudinal sectional area of this heat exchanger can be optimally used for heat recovery. This achieves good temperature compensation and good heat recovery.
  • the known heat exchanger could be used as efficient temperature compensation area only the rectangular part of the profile plates and thus not the entire longitudinal sectional area of this known heat exchanger for effective heat recovery.
  • each profile channel of the first triangular shape and each profile channel of the second triangular shape is fluidly with two profile channels of the rectangular shape or connected to a profile channel of the rectangular shape, which has twice the width compared to the width of the profile channel of each triangular shape, wherein the profile channels of the triangular shapes extend at an angle of 60 ° to the longitudinal direction.
  • the ratio of hypotenuse to height is 3.5 to 1.
  • the counterflow heat exchanger may be arranged in an air handling unit.
  • the ventilation device has an exhaust air chamber, an exhaust air intermediate chamber and an exhaust air chamber for the first air flow and a fresh air chamber, a fresh air intermediate chamber and a supply air chamber for the second air flow.
  • At least one Peltier element is arranged for cooling or heating the air streams between the exhaust air chamber and the fresh air chamber or the exhaust air chamber and the Zu Kunststoffsch, wherein the Peltier element forms a partition wall between the exhaust air chamber and the fresh air chamber or the exhaust air chamber and the supply air chamber substantially.
  • the countercurrent heat exchanger has individual, superimposed profile plates 1, 2, wherein each profile plate as a whole hexagonal is trained.
  • the profiled plates 1 for a first air stream 3 and the profiled plates 2 for a second air stream 4 are alternately superimposed, wherein the profiled plates 1 are rotated for the first air stream 3 and the profile plates 2 for the second air stream 4 in the plate plane by 180 ° against each other.
  • a release layer 5 is arranged between each profile plate 1 for the first air stream 3 and each profile plate 2 for the second air stream 4.
  • the separating layer 5 as shown schematically in FIG. 5 only on a small area of its surface, has embossing with diamond or scale pattern 15. As a result, an improved heat exchange is achieved.
  • the profile plates 1, 2 and the separating layers 5 may be made of plastic or metal such as aluminum, copper, steel or the like.
  • Each profile plate 1, 2 has a wave-shaped profile and consists of a first triangular shape 6, a second triangular shape 7 and a rectangular shape 8.
  • Each triangular shape 6, 7 is made so that each profile channel 12 of the triangular shape 6 and each profile channel 13 of the triangular shape 7 to two profile channels 14 of the rectangular shape 8 connects exactly.
  • This accurate determination of the widths of the profile channels 12, 13 and 14 is achieved by cutting or punching each triangular shape 6, 7 from a material such that the ratio of hypotenuse to height is 3.5 to 1 for each triangular shape.
  • the triangular shapes 6, 7 are identical.
  • the profile channels 12, 13 of the triangular shapes 6, 7 run obliquely, in particular at an angle of approximately 60 °, to the longitudinal direction 9, while the profile channels 14 of the rectangular shape 8 run parallel to the longitudinal direction 9.
  • the first air flow 3 flows through the profile channels 13 of the second triangular shape 7 to the profile channels 14 of the rectangular shape 8 and exits via the profile channels 12 of the first triangular shape 6.
  • the counter air flow or second air flow 4 basically flows in the same way through the profile plate 2, which is constructed identically to the profile plate 1. However, the profile plate 2 is rotated relative to the profile plate 1 in the plate plane by 180 °.
  • the profile plates 1, 2 may be formed either in one piece or in three parts according to their shapes.
  • the profile plates 1, 2 and the separating layers 5 are superimposed in a corresponding manner and provided with a base plate and a closure plate.
  • the items can be assembled into a compact design.
  • This countercurrent heat exchanger according to the invention gives a very high heat exchanger performance with small dimensions.
