00 00 The invention relates to home appliances, more specifically to air expansion refrigeration machines. A vortex tube is known, containing an energy separation chamber with a cooled wall and an internal coil spaced inside the chamber for additional cooling of the peripheral flow 13. However, this pipe is characterized by structural complexity. The vortex is also known to contain a compressed gas nozzle, a cooled flow diaphragm and a finned energy chamber. . separation with a cooling jacket. The fins are made on the outer perpendicular of the camera inside the shirt in the form of a corrugated tape. The water circulating in the jacket cools the ssaM & py energy separation 2}. However, such a tube has a non-sufficient thermodynamic efficiency due to the fact that the internal heat transfer surface of the chamber is made smooth for each other. Thermodynamic efficiency can be enhanced if the inner surface of the chamber of energetic separation is finned. In this case, the thermodynamic efficiency increases due to an increase in the heat-transfer surface from the side of the heated flow and, in addition, due to the additional spin-up of the heated flow on the surface of the riper. Closest to the proposed supply is a vortex tube, which contains a cooled energy separation chamber with a nozzle inlet and a beer trap. mu cold runout. At a distance of 2-3 calibers from the nozzle inlet, the chamber is equipped with ribs made in the form of corrugations from the wall of the chamber itself and placed along a helical line, which comes with the direction of twist of the compressed gas. Known vortex trdgba works as follows. The compressed gas enters the nozzle inlet and is divided into cooled and heated flows in the energy separation chamber. The emitted flow enters from the pipe through the diaphragm, and the heated flow through the throttle valve in the opposite direction, releasing heat through the walls of the corrugations oh / winter C 3. However, in this tube, there is no provision for intensive forced cooling of the energy separation chamber, which reduces those 4dynamic efficiency. In addition, the execution. the walls of the corrugated chamber greatly complicate the manufacture of the pipe. The purpose of the invention is to increase thermal efficiency. The goal is achieved by the fact that in the vortex tube containing the chamber of energy separation with ribbed cooled wall and nozzle inlet, the outlet diaphragm of the cooled stream and the throttle valve at the outlet of the heated stream, the wall of the chamber of energy separation is simple. coil with hermetically interconnected coils. FIG. 1 schematically shows the proposed vortex tube; in fig. 2 is a sectional view in FIG. 1. The vortex tube contains an energy separation chamber 1 with a nozzle inlet 2, a diaphragm 3 of the cooled flow outlet and a throttle valve 4 on the opposite end of the chamber 1, which serves to regulate the flow of the cooled and heated flows. At a length starting at a distance of 2-3 calibers from the nozzle inlet. 2, the wall of the chamber {1 1 is formed by a hake {{{}} with a tightly interconnected coil 5 of the prostatic coil 6 bent in a straight line coinciding with the direction of the gas in chamber 1. The diameters of coils 5 gradually increase in the direction of the throttle valve 4, forming a conical part chambers 1. The coil 6 has an inlet 7 and an outlet (8, respectively, for supplying and discharging the cooled liquid. The tightness of the connection of the coils 5 is provided, for example, by soldering. The proposed vortex tube works as follows. Compressed gas enters the nozzle inlet 2 chambers 1 1 1 in which the cooled and heated flows are divided. The cooled flow is removed from chamber 1 through diaphragm 3, and the heated flow through throttle valve 4. In the process of moving to valve 4, the heated flow is cooled, washing the surface tightly connected between by soldering the coils 5 of the coil 6, in which coolant flows through the pipe 7, is discharged from the coil 6 through the pipe 8.

BBIU of the fact that the wall of chamber 1 is made of a coil 6, inside which a very large flow occurs, {significantly improved cooling of the heated flow, FOC) increases the thermoannual I effect of the vortex tube.
