Definitions

  • the invention relates to a heat exchanger according to the preamble of claim 1.
  • Such heat exchangers are used, for example, in cooling towers.
  • a brine to be cooled is transported through a pipe register, which is sprinkled with water from the outside and in counterflow from
  • DE 32 16 877 C1 discloses a heat exchange element which can be installed in a pipe with a rectangular cross section and which consists of at least one mat body formed from flexible plastic tubes of approximately 2 mm in diameter, so-called capillary tubes, which intersect in a lattice manner.
  • This represents a wall penetrating the pipeline transversely to its longitudinal direction and, by folding around lines perpendicular to its axis, can be formed into a heat exchange element having a plurality of layers connected in series from one another and consisting of pipes which cross in a grid-like manner.
  • this is not sprinkled with water.
  • the tube register consists of parallel capillary tubes which are folded such that they are bent back by one or more lines perpendicular to their longitudinal direction to form layers of the tube register lying one above the other, and that the spaces between the capillary tubes are at least partially are filled with foam, compared to conventional heat exchangers, the heat exchange surface is multiplied on the one hand by the capillary tubes, which have a much smaller diameter than the tubes previously used, and on the other hand by the use of the foam.
  • the capillary tubes which are advantageously made of plastic, and the foam are inexpensive to manufacture.
  • the foam advantageously consists of mats arranged between adjacent layers of the capillary tubes or the space between the capillary tubes is completely foamed.
  • a conventional smooth tube heat exchanger made of tubes with an outer diameter of, for example, 15 mm and a depth of 100 cm has a heat exchange area of 60 m 2 per m 2 of air entry area.
  • these tubes are replaced by capillary tubes with an outer diameter of, for example, 3 mm, this area already increases to five times, namely 300 m 2 / m 2 air inlet area.
  • the foam takes up about 50% of the heat exchanger volume, so that the length of the Capillary tubes are cut by about 50%. Nevertheless, the heat exchange area of the heat exchanger increases to approximately 800 m 2 / m 2 of air entry area, since the foam itself has an internal surface area of approximately 1200 m 2 / m 3 .
  • a multistage mass and heat transfer is achieved in this way by the heat exchanger according to the invention. This consists successively of heating the water on the first tube layer, cooling the water by evaporation in the first foam layer, heating the water on the second tube layer, cooling the water by evaporation in the second foam layer, and so on.
  • the invention is explained in more detail below with reference to exemplary embodiments shown in the figures. Show it:
  • Fig. 1 is a schematic representation of a
  • Fig. 2 is a schematic representation of a
  • FIG. 3 shows a schematic illustration of the heat exchanger according to FIG. 2 used in a cooling tower in section in the plane of a capillary tube.
  • the individual capillary tubes 1 are folded in a meandering shape, so that they each extend over several layers.
  • brine to be cooled is supplied, which leaves the respective capillary tube 1 at its lower end in the cooled state.
  • the tube register consisting of the capillary tubes 1 is evenly sprinkled with water from above and flowed through by air supplied from below. Since the brine is piped from top to bottom, it is co-current with the water and with the air in counterflow. The heat required to evaporate the water is extracted from the brine so that it is cooled.
  • Capillary tubes 1 a mat made of foam 2 is arranged. Such a mat is preferably located between all adjacent capillary tube layers. Due to the large inner surface of the foam 2, the surface available for evaporation of the water is multiplied, so that the cooling effect is considerably improved.
  • Fig. 2 shows a heat exchanger in which the tube register consisting of the capillary tubes 1 was foamed in the block, so that the entire space between the capillary tubes 1 is filled with foam 2.
  • the heat exchange area can thus be increased to approximately 1200 m 2 / m 2 air inlet area under the conditions mentioned in the previous example.
  • FIG. 3 schematically shows the use of the heat exchanger in a closed cooling tower.
  • the air is adiabatically pre-cooled by evaporation in a known filler body before being introduced into the heat exchanger, and at the same time cleaned.
  • the foam mats can be wave-shaped transversely to the longitudinal direction of the capillary tubes 1.
  • the pipes are fixed in their position and are at a fixed distance from one another.
  • several capillary tubes can be guided in parallel be to avoid a pressure drop on the water side.
  • the heat exchanger according to the invention can not only be used for cooling the fluid flowing through the capillary tubes, but can also be used for the reverse heat and mass transfer. If the temperature of the fluid is below the temperature of the supplied air, it can be cooled and dehumidified.
  • Another possible use of the heat exchanger is to increase the concentration of a salt solution by trickling it through the heat exchanger and supplying the necessary heat of evaporation via the fluid.
  • this process can also be carried out in reverse in order to cool the air flowing through.
  • the salt water is then cooled below the dew point temperature of the air via the fluid, so that water vapor from the air passes into the salt solution.
  • the heat of condensation released is dissipated via the fluid.
  • capillary tubes for the heat exchanger, which are already covered with a foam layer during their manufacture.
  • the heat exchanger is then obtained directly by folding the capillary tubes.
  • the tubes can be manufactured in a two-stage extruder, in which in the first stage the

  • the material of the capillary tubes for example polypropylene, is expediently used as the base material of the foam layer. lent with a foaming agent. This has the advantage that the pipes can be welded without any problems since there is no foreign material.

Abstract

L'invention a pour objet un échangeur de chaleur muni d'un registre tubulaire à travers lequel circule un fluide à refroidir ou à réchauffer. Le registre tubulaire est arrosé par de l'eau, dans le sens de circulation du fluide, et est parcouru par de l'air, à contre-courant du fluide. Le registre tubulaire est formé de tubes capillaires (1) parallèles, pliés en couches. Les espaces entre les tubes sont remplis de produit mousse (2). On obtient ainsi une grande surface d'échange thermique. Un tel échangeur de chaleur est utilisé de préférence dans des tours de refroidissement.
