Definitions

  • ABSTRACT A vortex tube for converting pressure air to hot and cold air fractions and constructed of a body and cap assembled together with the cap and body forming a vortex chamber and a surrounding plenum chamber with a cold air passage extending outwardly from the cap and an elongate hot air passage extending outwardly of the body with the parts formed of plastic and shaped to provide a plug fit with each other and mounting an annular air filter screen therebetween and with a nozzle and valve unit threaded onto an end of the body providing for a plurality of control positions whereby either maximum cold air may be emitted from the unit or high temperature air can be emitted from the other end of the unit.
  • This invention pertains to vortex tubes and, more particularly, to a vortex tube usable in the automotive field as a device for cooling automatic chokes in the process of testing thereof.
  • Vortex tubes are well known in the art with the early developmentthereof being by Georges Ranque. As stated in a textbook entitled Refrigeration and Air Conditioning" byJordan and Priester, Copyright 1948 by Prentiss-Hall, the tube has been known as the Ranque tube, the I-Iilsch tube, or the vortex tube. Since that time, others have worked on developments of such vortex tubes. Typical of these additional developments are the Bramley U.S. Pat. No. 2,581,168, Fulton U.S. Pat. No. 3,173,273, and Fulton U.S. Pat. No. 3,208,229.
  • valve structure at the end thereof from which the hot gas is emitted including Tildon U.S. Pat. No. 3,074,243, l-lendel U.S.Pat. No. 2,893,214, and I-Iardebol et al. US. Pat. No. 2,955,432.
  • the vortex tube disclosed herein overcomes the problems and disadvantages of the prior art referred to above and enables the production of aninexpensive vortex tube having use in the automotive field as a choke tester wherein it is necessary to cool down an automatic chokeas-part' of the testing procedure and wherein the vortex; tube may selectively emit usable high temperature air from the opposite end thereof and with suitable fitting attachments.
  • a primary feature of the invention is to provide a vortex tube structure whereinthe structure is basically formed from a body and cap of plastic material which are shaped to provide an interfitting-plug relation and to define therebetween a vortex chamber and a surrounding plenum chamber with a series of air channels therebetween entering tangentially into the vortex chamber and with an annular air filter screen positioned in the plenum chamber and held in position by the ends thereof engaged in annular grooves in opposed faces of the cap and body.
  • An additional feature of the invention is to provide a vortex tube as defined in the preceding paragraph wherein the body has an elongate passage and with a nozzle and valve unit threadably fitted onto the body with a restricted air passage and a nonrestricted air passage and with the nozzle and valve unit being selectively positioned to either permit flow only through the restricted air passage when hot air is desired and, alternatively, to permit positioning of the unit in a variety of positions to permit relatively nonrestricted air flow through the nonrestricted passage when it is desired to have colder air emitted from the cold end of the vortex tube.
  • An object of the invention is to provide a new and improved vortex tube having the features set forth above and overcoming the problems and shortcomings of the prior art.
  • FIG. 1 is a perspective view of the vortex tube as usable as a choke tester
  • FIG. 2 is a vertical section, on an enlarged scale, taken generally along the line 2-2 in FIG. 1;
  • FIG. 3 is a vertical section taken generally along the line 3-3 in FIG. 2;
  • FIG. 4 is an enlarged view of the nozzle and valve unit shown in association with an end of the body and with the nozzle and valve unit in a different position from that shown in FIG. 2.
  • the vortex tube is shown generally in FIG. 1 and has a body, indicated generally at 10, associated with a cap, indicated generally at 11.
  • the body 10 has a central recess 15 to receive a plug section 16 of the cap 11 in interfitting relation and with an O-ring l7 captured therebetween to seal the body and cap together and with the body and cap having abutting surfaces 18.
  • the body and cap are held in assembled relation by a series of attaching members 20.
  • a vortex tube has a vortex chamber 21 surrounded by a plenum chamber 22 and with a series of air channels 23 extending between the vortex chamber 21 and the plenum chamber 22 and entering tangentially into the vortex chamber.
  • the body 10 has a central section 25 coacting with the plug section 16 of the cap 11 to define the vortex chamber therebetween and with the air channels 23 being formed by grooves in the face of the central section 25 of the body and completely defined by the end face of the plug section 16 of the cap.
  • an annular pervious filter screen 31 is positioned in the plenum chamber with the opposite ends thereof seated in an annular groove 32 in the body and an annular groove 33 in the cap.
  • the annular screen 31 can be inserted into the groove 32 in the body 10 and the cap then placed in final position to seat the opposite end of the annular filter screen 31 in the groove 33 of the cap.
  • the cap 11 has a cold air passage 40 with a slight taper formed in a tubular part 41 thereof and which is of a diameter less than the vortex chamber 21.
  • the body 10 has a lateral tubular extension 45 with a passage 46 which is of a diameter less than the vortex chamber 21 and of a diameter greater than the cold air passage 40.
  • a nozzle and valve unit, indicated generally at 50, is associated with the free end of the lateral tubular extension 45 of the body 10, and controls the operation of the vortex tube with regard to the temperature of the air fractions delivered from the vortex tube.
  • the nozzle and valve unit 50 is generally cup-shaped and has a transverse wall 51 with a restricted air passage 52 concentric with the air passage 46.
  • the end of the passage 52 has a metal insert 53 with an orifice 54 providing for restricted air flow therethrough.
  • the only air that can flow to the left, as viewed in FIG. 2 is the air which travels through the orifice 54. This results in relatively high temperature air being emitted therefrom, while air emitted from the cold air passage 40 is not of a significantly low temperature.
  • the nozzle and valve unit 50 is threadably mounted to the tubular extension 45 by threads, indicated at 55, and is in an inner limit position, as shown in FIG. 2, with the transverse wall 51 in engagement with an end of the tubular extension 45.
  • the nozzle and valve unit 50 may be rotated and, due to its threaded relation with the tubular extension 45, moved to one of several positions away from the inner limit position with one of these positions being shown in FIG. 4.
  • the transverse wall thereof is moved away from the end of the tubular extension 45 of the body whereby air flowing through the passage 46 can flow to a nonrestricted air passage 60 through a peripheral wall 61 of the nozzle and valve unit whereby air passing through the passage 46 is not at a maximum high temperature, but the cold air emitted from the cold air passage 40 may be at or near the maximum cold temperature.
