Definitions

  • the invention relates to a heat exchanger for heat transfer between two separate media.
  • Heat exchangers are often used in technology to realize a heat transfer between two media. So to be processed with heat exchangers media either heated or cooled.
  • a field of application for heat exchangers is the cooling of hot gases.
  • exhaust gases are expelled from the combustion chambers at temperatures of 1000 ° C. and more. In some cases it is desirable to cool these hot gases to temperatures of 50 ° C and less.
  • heat exchangers are typically used. In certain situations, where the space is cramped or where it is necessary for other reasons, to realize the exchange of heat on the shortest possible distance, heat exchangers of small or short design are desired.
  • no heat exchangers are known, which are particularly suitable for generating a high temperature gradient over the shortest distance (eg cooling of Hot gases from an inlet temperature of 1000 ° C and more to an outlet temperature of below 80 ° C, preferably below 50 ° C over a length of about 30 cm).
  • the heat exchanger according to the invention is characterized by a lying within a jacket tube inner tube, which is closed on one side.
  • the closed end of the inner tube is located on the inlet side of the jacket tube, in which, for example, to flow cooled hot gases or other hot media.
  • a coolant is first fed into the inner tube and cools both on the closed end face and on the pipe wall flowing past, to be cooled medium. From the inner tube, the cooling medium then passes into a spiral conduit wound around the inner tube and also leads there to a further cooling effect, before it leaves the heat exchanger.
  • the heat exchanger according to the invention is also suitable for conversely heating a cool medium flowing into the jacket tube with the aid of a heating medium flowing into the "coolant” inlet.
  • the terms “coolant inlet”, “coolant outlet” and “coolant outlet” are not to be construed as limited to a coolant, but they can equally well be used for a medium which is used for heating a medium flowing through the jacket pipe, thus a "warming agent" ,
  • An outlet pipe to be provided in accordance with claim 2 in the interior of the inner tube has the advantage that the coolant flowing into the inner tube must be distributed throughout the inner tube before it can pass into the spiral conduit through the outlet tube. In this way, the achieved on the wall of the inner tube cooling effect is enhanced, resulting in an overall better cooling performance and heat transfer performance of the heat exchanger. Of course, similar considerations apply to operation of the heat exchanger for heating a medium.
  • the spiral conduit is guided at least along the entire length of the inner tube surrounding it.
  • the individual turns of the spiral line are closely wound, but without touching. There must be a spacing between the individual turns of the spiral line so that contact can also take place between the medium to be cooled or heated and the surface of the spiral line through which the coolant or heat medium flows.
  • spiral duct is arranged at a radial distance to the wall of the inner tube and to the wall of the jacket tube, supports the desired turbulence of the flowing through the jacket tube medium and the associated increased heat exchange efficiency. It has been found that a radial distance of the spiral conduit to the wall of the inner tube, which is approximately equal to the radial distance of the spiral conduit to the wall of the jacket tube, shows particularly good results (claim 6).
  • At least the spiral duct of the heat exchanger consists of a material with good thermal conduction properties.
  • copper is preferably used, but other materials with good thermal conductivity properties are conceivable, such as, for example, silver.
  • the heat exchanger according to the invention is used to cool combustion gases from internal combustion engines, in particular combustion exhaust gases from motor vehicle engines.
  • a heat exchanger must, on the one hand, apply a high cooling power, in order to achieve that with approximately 1000 ° C and more emerging from the combustion chamber, hot exhaust gases to a temperature of 80 ° C and less, preferably below 50 ° C to cool.
  • the heat exchanger must also be of compact design, since the space in the exhaust system of the motor vehicle is limited.
  • the heat exchanger according to the invention is particularly well.
  • a heat exchanger 12 according to the invention is shown schematically in cross section.
  • the heat exchanger 12 according to the invention has a jacket tube 8, which opens via radial tapers in an inlet 1 shown in the drawing above and an outlet 2 shown in the drawing below.
  • This embodiment of the heat exchanger 12 is preferably designed for the cooling of hot gases.
  • the heat exchanger according to the invention can be used in all possible variants, including for cooling liquids, for heating gases or liquids or other heat transfers.
  • an inner tube 3 is arranged concentrically to this, which is closed at its front side facing the inlet 1 shown in the drawing above.
  • the closed end face of the inner tube 3 forms a baffle plate 11 for a medium flowing in via the inlet 1 into the heat exchanger 12, in particular gas.
  • this On the outlet 2 facing side of the inner tube 3, this has a coolant inlet 5, which is passed through the jacket tube 8 and connected to a coolant inlet 9.
  • Inside the inner tube 3 there is an outlet tube 6, which is drawn to just before the baffle plate 11 and there has an opening.
  • the outlet tube 6 leads out of the inner tube 3 and goes into a spiral conduit 7, which in tight turns, but with retention of a distance between the turns, along the entire length of the inner tube 3 to this is led around. At the end of the spiral line this goes into a coolant outlet 10, which is passed through the jacket tube 8.
  • the hot exhaust gases enter the jacket tube 8 via the inlet 1. There they meet the baffle plate 11, whereby the stream is divided and first turbulences arise. This is indicated schematically in the figure by corresponding arrows. There on the baffle plate 11 already takes place a first indirect contact with the flowing in the inner tube 3 cooling medium, so that already an initial cooling effect is effected.
  • the gas is deflected by the baffle plate 11, it enters the annular space formed between the casing tube 8 and the inner tube 3.
  • the spiral conduit which is arranged in this embodiment in the radial direction approximately centrally between the wall of the inner tube 3 and the wall of the outer tube 8.
  • the inflowing medium preferably gas, runs a markedly extended path within the jacket tube 8 and has intensive contact with the surfaces of the inner tube 3 and spiral conduit 7 which are traversed by the cooling medium.
  • the cooled medium preferably gas
  • the flow of the coolant from the coolant inlet 9 through the inner tube 3 and the spiral conduit 7 up to the coolant outlet 10 is also indicated by arrows.
  • the inner tube 3 has a diameter d of 60 mm, the diameter of the spiral line d s , measured from outer wall to outer wall, is 110 mm, the diameter D of the jacket tube 150 mm, the length L of the jacket tube 200 to 300 mm, the diameter of the inlet 1 and the outlet 2 (not indicated in the figures) about 50 to 60 mm.
  • a copper conduit is used as a spiral conduit 7 with a circular cross-section and a diameter of 15 mm.
  • This heat exchanger is used for cooling exhaust gases leaving about 1000 ° C. and more from an internal combustion engine up to temperatures of about 50 ° C.
  • n-butane is added at room temperature (about 25 ° C) in the coolant inlet, the n-butane has then left the coolant outlet at a temperature of about 120 ° C.
  • a 30 bar pump was used to promote the coolant n-butane.
  • water or another liquid or a liquid mixture can also be used as the coolant.
  • the heat exchanger according to the invention could be integrated into the exhaust system of a motor vehicle, for example as a replacement for a catalytic converter or a silencer.
  • the heat exchanger according to the invention is not limited to the use described in this embodiment, but can be used for cooling or heating of various media.
  • the heat exchanger can be used only for heat transfer.
