The invention relates to refrigeration, and in particular to installations using a vortex effect split the gas into hot and cold streams, and can be used in air-conditioning systems and drying of air and other gases.

Known vortex tube containing to allow the input camera power division installed in it rasvijetnim hot stream, aperture and resveritol least three radially arranged plates with a length of 1.8-2.0 diameter camera separation and installed at a distance of 2.2-2.5 diameter chamber from the aperture.

This famous vortex tube is characterized by a high thermodynamic efficiency. However, at high humidity of the compressed gas may icing surfaces of respirates cold stream, and after prolonged use of the vortex tube in this case and the blockage of the bore of the socket.

The purpose of the invention to increase thermodynamic efficiency and reliability of operation of the vortex tube.

This objective is achieved in that in the known vortex tube comprising allow the input chamber of the energy separation of the cooling jacket and the pipe with rasvijetnim cold flow, according to the invention the pipe with rasvijetnim cold stream is enclosed in a chamber for collecting condensate, pipe fitting made of input and output parts, posted with a guaranteed axial clearance, resveritol installed in the output side of the pipe, the camera condensate communicated with a cooling water jacket.

The conclusion of the socket with rasvijetnim cold flow into the chamber for collecting condensate eliminates the loss of cold from cold flow and thereby improve thermodynamic efficiency.

Running pipe from the input and in the cabin allows you to form between parts of a guaranteed slot gap and thereby to exclude the icing surfaces of respirates, therefore, to improve the reliability of operation of the vortex tube and its thermodynamic efficiency.

Message camera collect condensate from cooling water jacket allows the use of the resulting condensate in the cooling jacket and thereby to provide a refrigeration system energy separation, and consequently, to increase thermodynamic efficiency.

Comparison of the characteristics of the proposed technical solution with the characteristics of the prototype showed that the difference lies in the fact that the tube with rasvijetnim cold stream is enclosed in a chamber for collecting condensate, pipe fitting made of input and output parts, posted with a guaranteed axial clearance, resveritol installed in the output side of the pipe, the camera condensate communicated with a cooling water jacket, which allows to make a conclusion on the conformity of the proposed technical solution the criterion of "novelty". Analysis of the known technical solutions in this field of technology has shown that the features distinguishing the claimed solution to the prototype, not identified and therefore they provide the claimed technical solution according to the criterion of "significant differences".

The proposed solution is illustrated the

Vortex tube 1 includes allow input 2, the camera 3 of the energy separation of the cooling jacket 4 and the pipe 5 with rasvijetnim 6 cold stream. Pipe 5 with rasvijetnim 6 cold stream is enclosed in a chamber 7 for collecting condensate. The pipe 5 is made from the input 8 and output 9 parts, posted with a guaranteed axial clearance. Resveritol 6 is installed in the output portion 9 of the socket 5. Camera 7 condensate communicated with a cooling water jacket 4. The output from the camera 3 energy separation from the hot flow is a valve 10, which regulates the ratio of hot and cold streams, and the valve 11, which provides the necessary pressure and the boiling temperature of the condensate in the cooling jacket 4.

Vortex tube operates as follows.

Compressed gas enters tangentially through to allow input 2 into the chamber 3 of the energy division, where the twist is its division into hot and cold streams. Hot thread exits the perforated area of the camera 3 power split through the valve 10. Swirling cold stream, including ice particles and condensate resulting from cooling in the compressed gas of water vapor the circulation of cold flow in the zone of guaranteed axial clearance of the ice particles and condensate under the influence of centrifugal force are discarded through this gap into the chamber 7 of the condensate. Accumulating the condensate flows through the pipe 12 into the cooling jacket 4, where it is heated and evaporation, resulting in camera 3 energy separation is cooled.

Thus, by the conclusion of the socket with rasvijetnim cold flow into the chamber for collecting condensate, running pipe from the input and output parts, posted with a guaranteed axial clearance, and placement of respirates to the output side of the pipe, and a communication chamber for collecting condensate from the cooling water jacket it is possible to significantly improve thermodynamic efficiency of the vortex tube, as well as to improve the reliability of its work.

Application of the proposed design of the vortex tube allows you to increase thermodynamic efficiency by 10-15% in comparison with the existing vortex tube.

VORTEX the TUBE containing the nozzle enter the camera's energy division and nipple with rasvijetnim cold flow, characterized in that it further comprises a cooling jacket and chamber condensate collection, and baggage energy separation is placed in a cooling jacket, a pipe with rasvijetnim cold flow is installed in the camera, the om, resveritol installed in the outlet part of the nozzle and the chamber for collecting condensate communicated with a cooling water jacket.
