Definitions

  • the invention relates to a heat exchanger in which the fluids participating in the heat exchange are guided in a single tube in cocurrent or countercurrent.
  • the surface sections through which heat is transferred from one fluid to the other should be dimensioned as large as possible in a heat exchanger.
  • this requirement means that the larger the total heat exchange surface, the larger the space occupied by the respective heat exchanger.
  • the fluids in a heat exchanger are usually guided in elongated components, for example pipes, such heat exchangers not only require a large amount of space, but also e.g. cylindrical shape, which means a disproportionately large space requirement, especially in small systems.
  • coaxial condensers and evaporators have coaxial tubes, which are arranged helically or helically. To produce these heat exchangers, a first tube is pushed into a second so that there is a coaxial arrangement and then these tubes are bent into a spiral.
  • the disadvantage of this design is that the inner tube with its outer jacket comes to rest on the inner jacket of the outer tube, which has the consequence that there is a severe impairment of the heat transfer from one fluid to the other at the linear contact point of the two tubes.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, solves the problem of creating a heat exchanger in which the fluids participating in the heat exchange are each guided in a single tube, in which the respective tubes lie flat against one another along their entire length.
  • the advantages achieved by the invention are essentially to be seen in the fact that the heat exchanger takes up a small space for a given flow volume and given total heat exchange surface, and that the shape of the heat exchanger can be easily adapted to predetermined spatial conditions.
  • the heat exchanger according to FIG. 1 has a first tube 1 and a second tube 2.
  • the first tube 1 has an inlet or outlet 3 and an outlet or inlet 5.
  • the second tube 2 has an inlet or outlet 4 and an outlet or inlet 6.
  • the fluids flowing through this heat exchanger obviously flow in cocurrent or countercurrent, depending on the respective technical circumstances.
  • the two tubes 1, 2 are close together and are spirally laid in turns. The spiral described by the pipes, i.e. the two spirals, on a flat surface. Because this form of training can be regarded as practically two-dimensional, because the third dimension depends only on the tube thickness, this heat exchanger takes up a relatively small space.
  • the tubes do not have a circular cross-sectional shape. Accordingly, an embodiment with tubes of square cross-sectional shape is shown in FIG. 2. These tubes, which are arranged in the spiral shape mentioned and have a square cross-sectional shape, abut one another with side walls. The tubes are soldered together to achieve good heat transfer. Correspondingly, a solder, a solder metal 7 is arranged between the side walls of the tubes. Obviously, the soldering also gives the heat exchanger the necessary mechanical strength.
  • the manufacture of the heat exchanger is carried out as follows. First, the pipes 1, 2, in their original, rectilinear shape, are placed parallel next to each other. A ribbon-shaped solder, a ribbon-shaped solder metal, is inserted between these tubes in such a way that the arrangement shown in FIG. 2 is present, but only two tubes are present on average. The tubes and the solder are then connected to one another at points, for example at one end. The tubes 1, 2 with the solder 7 located between them are then laid in turns so that they assume the shape shown in FIG. 1. Thereafter, tubes with 1, 2 are fixed in the wound position with the solder 7 by at least one further punctiform connection. The entire arrangement is then immersed in an induction bath. The solder melts in it, so that the pipes 1, 2 are soldered along their entire longitudinal extent and the heat exchanger is thus produced.
  • the tubes 1, 2 do not necessarily have to have the square cross-sectional shape shown in FIG. 2.
  • 3 shows an embodiment in which the tubes are in a triangular cross-sectional shape, the solder 7 again being arranged between the abutting side walls of the tubes.
  • This embodiment according to FIG. 3 is also a space-saving design.
  • these walls are structured according to a further embodiment.
  • Such a design is shown in FIG. 4.
  • the cross-sectional area of the first tube 1 is different from the cross-sectional surface of the second tube 2.
  • a vaporous fluid flows through the first pipe 1 and water flows through the second pipe 2, an application which is present, for example, in heat pump systems.
  • Side walls of the pipes 1, 2 which abut one another have successive depressions 9 and projections 8. These tooth-like designs mesh with one another, so that the area dimension of the heat transfer areas is increased.
  • the tubes are not soldered to one another here.
  • the tubes 1, 2 again have the same cross-sectional area and are connected to one another again with a solder 7.
  • the difference to the embodiment of FIG. 4 is that the two side walls of the pipes 1, 2 through which the heat transfer takes place have an increased areal area, the walls here being simply wave-shaped, the respective wave troughs and wave peaks engaging with one another.
  • FIG. 6 A further embodiment of the heat exchanger is shown in FIG. 6. It has been said in the description of FIG. 1 that the spiral, ie the two Spirals, which are described by the tubes 1,2, lie on a flat surface. 6, the tubes are also deformed in such a way that they describe the envelope of a hollow circular cone.
  • the advantage of this design is that there is a clear gradient in the pipes. A gradient is often necessary due to a given medium, for example if a medium enters in the gaseous state and is liquefied in the heat exchanger, and thus must have a gradient with respect to the horizontal.
  • the envelope of the heat exchanger i.e. at least its projection onto a surface, not circular (it should be understood that here the envelope of the spiral is viewed as a circle for simplicity).
  • the envelope curve can thus describe a rectangle, as in FIG. 6 or a hexagon as in FIG. 7, or any other polygon, polygon.
  • the heat exchanger can now be designed in any spatial and planar form, such that it can be arranged in an entire system, for example a heat pump system, in such a way that it takes up the smallest amount of space.
  • FIG. 9 shows an embodiment in which the tubes 1, 2 are arranged in the form of a hollow cylinder.
  • This embodiment has the particular advantage that apparatus, e.g. Pumps and other units of a plant containing the heat exchanger, e.g. a heat pump system, can be arranged in the cylindrical cavity circumscribed by the pipes 1,2. Significant space savings are possible.
