Definitions

  • the invention relates to a cooler for rotary compressors operating with oil injection according to the preamble of claim 1.
  • a cooler for screw compressors is known in which a ring cooler is divided perpendicular to the axis into two sections, one of which is designed for cooling oil and the other for cooling the compressed air supplied by the compressor. With this construction, there is a certain longitudinal dimension of the ring cooler on the compressor unit.
  • the invention has for its object to provide a cooler of the type specified so that it can be attached to a compact compressor unit to save space.
  • 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, for example welded in.
  • 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 level. 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 designed 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 protrudes less far into the separation space, so that there is no reduction in cross-section at this point relative 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 4 additional baffle and deflection surfaces for the compressed air in the insert.
  • 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.

Claims (5)

1.- Dispositif de refroidissement pour compresseur rotatif opérant avec injection d'huile, dans lequel un dispositif de refroidissement annulaire est subdivisé en deux segments dont l'un est alors destiné à refroidir de l'huile et l'autre à refroidir ultérieurement l'air comprimé fourni par le compresseur, étant entendu que chaque segment est pourvu d'une entrée et d'une sortie pour l'agent à refroidir qui lui est attribué, caractérisé en ce que le dispositif de refroidissement annulaire est subdivisé en deux secteurs annulaires (1, 2) formant les segments.
2.- Dispositif de refroidissement suivant la revendication 1, caractérisé en ce qu'entre les secteurs annulaires (1, 2) sont disposées des pièces insérées en forme de secteur (3, 4) qui ont la forme d'éléments de séparation entre les segments du dispositif et qui sont pourvues de raccords pour des conduites d'air comprimé et des conduites d'huile.
3.- Dispositif de refroidissement suivant les revendications 1 et 2, caractérisé en ce que les secteurs annulaires (1, 2) ne sont pas pareils.
4.- Dispositif de refroidissement suivant les revendications 1 à 3, caractérisé en ce qu'un séparateur de condensat avec des sorties de condensat et d'air comprimé radiales (9, 11) est formé dans une des pièces insérées (4).
5.- Dispositif de refroidissement suivant la revendication 4, caractérisé en ce que des chicanes (12) sont prévues dans le sens circonférentiel de part et d'autre de la sortie d'air comprimé (9).
