Definitions

  • the invention relates to a surface cooler as an air cooler according to the preamble of the main claim.
  • weather coolers For cooling mine weather, surface coolers are known as weather coolers, in which the weather (air) and the cooling water are separated from one another, the cooling water being passed through finned pipes made of a good heat-conducting material and bringing the weather into contact with the surface of these pipes will.
  • a fan is connected upstream or downstream of the weather cooler, which feeds a certain weather current to the cooler.
  • the cooler itself usually consists of an inlet hood from the actual heat exchanger, i. H. the cooling register, and an outlet hood, wherein a droplet separator and a condensate outlet can also be provided in front of the outlet hood.
  • Cooling water is pumped through the pipes of the cooling register, which is usually in the most thermodynamically effective manner, namely in countercurrent to Weather current, is led.
  • the pipes of the cooling register are assigned a distributor pipe at the beginning and a header pipe at the end of the register.
  • a surface cooler is known from DE-GM 86 31 320 in which the exchanger performance is improved and which should be mobile with high air performance.
  • this known arrangement also uses finned tubes that have a tendency to become blocked and contaminated.
  • the heat transfer in finned tubes is also only unsatisfactory that the heat transfer in finned tubes decreases with increasing size of the fin.
  • pipes with a large diameter are not to be used, since no turbulent flow of the cooling medium is effected within the pipes with a large diameter, but this is necessary to ensure the necessary heat transfer.
  • large pipes require a lot of space and create a large air resistance.
  • the finned tubes are equipped with very narrow fins, but this leads to contamination, especially when such surface coolers are used in underground mining operations.
  • the invention has for its object to provide a surface cooler of the generic type, in which a good heat transfer from the inside of the tube to the medium flowing around the tubes is possible, on the other hand, the flow resistance for the cooling water is not increased too much and finally the resistance against air flowing through is not increased too much.
  • this surface cooler should be usable in heavily soiled rooms, so that it e.g. B. can also be easily used underground.
  • the incoming air is opposed to a large surface of the exchanger tube, but this air now does not create a dead space behind the exchanger tube, as is the case with round tubes, but the large drop-shaped design that follows the round part of the tube Wall surface created, where the air passes and can continue to lead to an effective heat transfer.
  • the drop shape of the tube creates a very good heat transfer with a relatively small surface area and that the smooth tube used according to the invention leads to good self-cleaning of the surface cooler by means of the condensate water that occurs.
  • Fig. 1 denotes a surface cooler, which essentially consists of a housing 2, with an air inlet 3 and an air outlet 4.
  • a heat exchanger is arranged in the housing 2, the cooling register 5 of which is formed by a plurality of tubes 7 arranged in parallel and one above the other is formed, which are designed as smooth tubes with a teardrop shape in cross section, as shown more clearly in FIG. 2.
  • the inlet for the cold water to be supplied to the cooling register 5 can be seen at 9 in FIG. 1, and the outlet of the heated water which has flowed through the cooling register 5 can be seen at 10.
  • the water fed to the inlet 9 reaches the cooling register 5 via a distributor pipe 12 which is connected to the first series of pipes 7 of the cooling register 5.
  • the inlet 3 for the dirty air leads inside the housing 2 to a nozzle chamber 16, from which the air is now guided across the cooling register 5, then into a diffuser chamber 17 and from there to the outlet 4.
  • Fig. 2 shows that the tubes 7 have a teardrop shape when viewed in cross section, the round wall 8 of the tube 7 being flown by the air supplied through the inlet 3, which then, after flowing around the tube 7, also drops out to the outside of the upper, creates drop-shaped area 11 of the tube 7 and thus a large exchanger creates space.
