Definitions

  • the invention relates to a heat exchanger, in particular for heat pump systems, consisting of a secondary part, which consists of at least one helically turned pipe that guides the coolant, and a primary part with a heat pipe that also surrounds the pipe coil of the secondary part and also helical jacket pipe.
  • heat pump systems essentially two heat exchangers are used, namely an evaporator, in which the heat carrier of the primary circuit gives off its heat to a secondary circuit, which is also a central coolant circuit, and a condenser, in which the central coolant circuit in turn transfers its heat to a heat-emitting circuit transmits.
  • the aim in both heat exchangers is to achieve the greatest possible heat transfer and the lowest possible pressure loss.
  • the exchange area is increased, among other things, or the size - with the same exchange area - is reduced by a bundle of parallel tubes forming the secondary part, the ends of which are located in distributor caps Twisting the distributor caps against each other is first twisted around a central axis and then inserted into a jacket tube forming the primary part. The casing tube is then formed into a screw that is in contact with the gears. Both the twisted tube bundle of the secondary part and the jacket tube of the primary part thus form a coaxial screw, so that a small size with a large heat exchange surface is obtained.
  • the invention has for its object to achieve a further increase in the heat exchange area and at the same time an increase in the heat transfer coefficient with the same size, in order to maintain a high efficiency, especially when using the heat exchanger in heat pump systems.
  • the helically coiled tube of the secondary part with an approximately horizontal screw axis is arranged in the casing tube of the primary part and maintains its approximately horizontal screw axis, and in that the tube of the secondary part opens into a core tube near the heat transfer outlet of the primary part, which in the Screw axis of the tube of the secondary part is arranged and the outlet of which is located near the inlet of the primary part, so that the coolant in the secondary part first flows in cocurrent and then in countercurrent.
  • the helically coiled tube of the Sekun The surrounding casing tube is helically coiled with it, the screw axis of which is arranged essentially vertically, with the result that the horizontal screw axis of the tube is approximately retained in the secondary part, which results in a significant increase in the exchange area with the same size.
  • the heat transfer medium in Primary part is first performed in direct current with the coolant in the secondary part.
  • the direction of flow in the secondary part at the mouth of the helical tube into the core tube is reversed, so that the coolant is returned in countercurrent.
  • three parallel helically coiled tubes for the coolant are provided in the secondary part, each of which opens into the core tube near the heat transfer outlet of the primary part.
  • the helixes of all three tubes can lie side by side in the axial or radial direction.
  • the core tube has a larger cross section than the sum of the cross sections of the helically coiled tubes of the secondary part, the heat exchanger preferably being controlled so that the vapor phase is only on Transition between helically coiled tubes and core tube takes place.
  • Fig. 1 shows an evaporator, the primary part of which is formed from a cylindrical container 1.
  • the container 1 has an inlet 3 for the heat transfer medium, z. B. water, and below a drain 4.
  • the secondary part is formed by a helically extending tube 6 in the container 1, the screw axis 2 of which is arranged vertically and which has an inlet 5 for a coolant, for. B. Freon, and has a drain 7 below.
  • the level of the liquid phase - in the presence of the gaseous phase - is set in an inclined position, as is indicated in FIG. 1, and which is due to the vectorial addition of gravity t and which the centrifugal force c resulting from the flow velocity.
  • the liquid level is normal to the resultant R.
  • FIG. 4 shows a heat exchanger according to the invention in function as an evaporator for use in a water / water heat pump system.
  • the heat exchanger has a jacket tube 8 as the primary part, which is shown in a straight line in FIG. 4 for reasons of clarity, but in reality runs helically, as will be explained with reference to FIG. 5.
  • At one end of the casing tube 8 there is an inlet 9 for the heat transfer medium, here water, and at the other end an outlet 10 for the water.
  • the jacket pipe 8 is part of a known closed water circuit, which also includes a pipe system, not shown, that z. B. is arranged in the earth to absorb geothermal energy
  • the water flowing through the inlet 9 into the casing tube 8 is warmer than the water flowing out at the outlet 10.
  • a central core tube 11 is arranged in the casing tube 8 as part of the secondary circuit.
  • three parallel copper tubes 12, 13 and 14 are arranged in a helical shape.
  • the copper tubes 12, 13 and 14 are passed through the casing tube 8 and with an inlet box 15 for the coolant, for. B. Freon, which flows to the inlet box 15 through a line 16, the supply being controlled by a thermal valve 17.
  • the core tube 11 is closed by a face plate 18, and the ends of the copper tubes 12, 13 and 14 are each via a connection 19, 20 and 21, respectively, on the
  • the circumference of the core tube 11 is offset by 120 °, connected to the core tube 11 near its closed end.
  • the core tube 11 is at the corresponding end of the casing tube 8, i.e. H. near the inlet 9, through the jacket tube 8 to the outside to form an outlet connection for the coolant, as can be seen from FIG. 4.
  • the casing tube 8 consists of an insulating material, for example plastic or rubber.
  • the other components of the pipe system located outside the casing pipe 8 can also be thermally insulated.
  • FIG. 1 shows an embodiment of the heat exchanger (evaporator or condenser) according to the invention which is used in practice.
  • 5 corresponds to the casing pipe 8 shown in FIG. 4 in a straight line, while the helically wound pipe (s) 12, 13, 14 of the secondary part according to FIG. 4 can be seen in FIG. 5 at the broken point of the casing pipe 22 and is designated 25.
  • the heat exchanger according to FIG. 5 is thus obtained from the linear structure according to FIG. 4 in that the casing tube of the primary part is helically deformed about a vertical axis with the built-in coil of the secondary part. The horizontal screw axis of the inner coil is largely preserved.
  • the compressor 26 is arranged in the screw axis of the casing tube 22 and is therefore enveloped by the casing tube 22.
  • the heat transfer medium enters the jacket pipe via the inlet 24 and leaves it via the outlet 23 (corresponding to 9 and 10 in FIG. 4).
  • the inlet box 15 and thermo valve 17 and the outlet of the core tube 11 of the secondary part are not shown in FIG. 5. They are located on the lower turn of the screw of the casing tube 22 near the inlet 24 of the primary part.
  • the three helically extending tubes 12, 13 and 14 of the secondary part can each be returned to the inlet individually, whereby then the core pipe 11 is replaced by the return pipes.
  • the casing tube 8 (22) can also be coiled in a horizontal plane in the manner of a spiral.
