Definitions

  • the invention relates to a cooler, in particular for rotary compressors working with oil injection.
  • the invention has for its object to design such a cooler so that it can be arranged in a space-saving manner and used for cooling different media.
  • annular cooler is divided into two sections, one of which is designed to cool the oil and the other to cool the compressed air supplied by the compressor.
  • Such a ring cooler is particularly suitable for a compact compressor system with screw compressor, oil separator and air filter integrated in a housing, as described, for example, in German patent application P 29 38 757.
  • the compressor system has small dimensions, to which the cooler can be adapted by dividing it into ring sectors in a compact design.
  • sector-shaped inserts are arranged between the ring sectors of the cooler, which are designed as separating elements between the cooler sections and are provided with connections for compressed air or oil.
  • the sector-shaped cooler sections can extend over different angular ranges.
  • a condensate separator is formed in one of the sector-shaped inserts, which is provided with radially arranged connections for the condensate drain and the compressed air outlet, so that these connections are easily accessible.
  • baffles can be provided around the radially directed outlet opening for compressed air, which favor effective condensate separation.
  • FIG. 1 shows a ring cooler which is constructed from two ring-shaped cooler sections 1 and 2, between which sector-shaped insert parts 3 and 4 are fastened / welded, for example.
  • Two inlet openings or connecting pieces are formed on the insert part 3, between which a partition 5 is arranged.
  • the inlet 6 is for oil and the inlet 7 for compressed air.
  • the cooler section 1, which extends approximately over 180 °, serves as an oil cooler, while the cooler section 2, which extends approximately over 90 °, serves as an air aftercooler.
  • the insert parts 3 and 4 each occupy an angular range of approximately 30-45 °.
  • the insert part 3 is ring-shaped in accordance with the dimensions of the cooling sections 1 and 2 and is provided with axially directed inlet openings 6 and 7, the insert part 4 has an axially directed bore 8 and a radially directed outlet opening 9 for the compressed air only for the oil outlet.
  • the insert 4 is protruding on the outer circumference of the cooler, the radially outer boundary walls of this insert 4 being approximately vertical and horizontal. Due to the oblique arrangement of the partition 10, a condensate separator with a condensate drain 11 is formed on the compressed air side and is directed downward.
  • baffles 12 are arranged above and below the compressed air outlet bore, which can be formed as ribs in the insert 4, which extend between the front and rear walls of the insert 4. These ribs 12 are curved in the view from the right in FIG. 1. The lower rib 12 projects less far into the deposition space, so that there is no reduction in cross-section at this point with respect to the partition 10.
  • the cooler sections 1 and 2 can be designed such that the compressed air flows through them radially or axially.
  • the arrangement according to FIG. 2 is more advantageous in that the radiator fins 13 of a section can be designed identically, while the shell-shaped radiator fins 14 of the arrangement according to FIG. 3 have different dimensions.
  • the insert 4 with the condensate separator can also be designed in a different way. So it is also possible to arrange the condensate drain 11 axially directed laterally on the insert, while for the compressed air outlet a pipe socket extending from below into the condenser separator can be provided, over which an impact surface for the compressed air is arranged, so that the compressed air radially downward can be deducted at the location of the condensate drain 11 shown in FIG. 1. It is also possible to provide additional impact and deflection surfaces for the compressed air in the insert 4.
  • the thickness dimension of the insert parts 3 and 4 corresponds to that of the ring sectors 1 and 2.
  • the separation chamber can be filled with packing to further support the separation effect.
