(57) Abstract:Usage: in the design of devices using a vortex effect the Market for changing the temperature of the gas stream. The inventive vortex tube has a spiral working surface (the snail), inlet and outlet nozzles. New in the invention is that the snail has a spiral working surface inclined in the direction of the outlet pipe. This improves workflow efficiency, 3 C.p. f-crystals, 5 Il. The invention relates to the use of a vortex effect the Market for changing the temperature (cooling or heating) of a moving gas stream.A device for changing the temperature of the gas stream containing the inlet pipe, tangentially directed into the spiral working surface (the snail), coupled to the output channels. Called this device "vortex tube". Implemented in the vortex tube so-called "effect Wound", which occurs when the tangential supply and the unwinding of the gas stream through the cochlea, resulting in cooling of some parts 
Used vortex tube, mainly for trubka "cold" and "hot", having a different diameter, of which while working out two gas flow having a substantially different temperature, and in hot tube goes a significantly larger amount of gas than in the cold. Therefore, there are design not only "cooling" and "heating" vortex tubes.Internal working surface known snails is based mainly on the spiral of Archimedes, the forming of which is parallel to the axis of the vortex tube, i.e., we can say that forming a spiral working surface parallel to the axis of the spiral (see  S. 9 and Fig. 1.4, S. 11). This snail is shown in Fig. 1.Schematically works known vortex tube as follows. Free rectilinear movement of the gas stream supplied to the input pipe to the cochlea becomes circular, internally, with its peripheral layers are compacted, and the Central are sparse. When you exit the snails rotating gas begins to split into two streams peripheral sealed his layers coming through the hot pipe of larger diameter become warmer than at the entrance. Therefore, a vortex tube can be used to heat the gas. Sparse layers located closer to the center of the tra. So it turns out that in a heated pipe goes considerably more gas than cold.Therefore, the known design of the cooling of the vortex tube has a low efficiency. This is a disadvantage.Low cooling capacity is known of the vortex tube is due to the fact that unstable turbulent nature of the gas to flow inside the vortex tube does not allow the full capabilities of cooling due to adiabatic expansion, which is implemented in the vortex tube. This can be explained by the imperfection of the organization of the circular motion of the gas stream.The objective of the proposed technical solution is to reduce this drawback by increasing the efficiency of the temperature change of the gas flow in the vortex tube, i.e., improving the efficiency of either cooling or heating.This objective is achieved in that the snail is performed with a beveled surface, i.e., forming a spiral working surface is at an angle to the axis of the spiral.The essence of the invention lies in the fact that the beveled surface snails makes more intensity to produce RA what is the lateral force component, forcing him some additional part to flow in a given direction.In Fig. 1A depicts a snail in the plan with the working surface is made in a spiral of Archimedes; Fig. 1B shows the cross section of the known snail forming its working surface parallel to the axis of the vortex tube (angle 0o); Fig. 2 and 3 shows the cross section of the proposed snails forming its working surface is not parallel to the axis of the vortex tube and makes it a kind of angle a.The device has no moving parts, therefore the dynamics of the device is determined by a motion filed in a vortex tube gas that is not part of the device in question.The proposed design is as follows. When the flow of gas in the spiral surface of the cochlea is unwinding and separation temperature fractions. Due to the inclination of the working surface directed toward the one of the output nozzle, the stream offset in the desired direction. Therefore, one of the nozzles will flow more gas than when using the known snail. In addition, thanks to the emergence (Fig. 2) broadening of the cavity (P), resulting due to the "bevel" (srmu, using the snail, you can increase one output stream by reducing the flow from the other of the outlet pipe at a constant total flow. That is, the snail inclined spiral surface allows you to redistribute the flow inside the vortex tube relative to the output sockets.Preliminary studies have shown that depending on the task and on the composition of the refrigerant gas, the half angle of the working solution of the spiral surface of the cochlea (angle) must be in the range from 1.5oto 24o, i.e., the angle formed between the spiral working surface and the axis of the spiral is equal to 1.5o.24oi.e. the whole solution of the angle between the generatrix of the opposed spaced parts of the spiral working surface of the cochlea is within 3.48o.Possible that the snail is performed with variable angle - like "twisted spiral. For example, a spiral, with the input "zero" angle, gradually twists, and at the output of the tilt angle reaches a maximum of 1.5o.24ovalues (Fig. 3 and 5). Therefore, such a device has a variable angle of inclination of the helical surface to the axis of the helix, i.e., has nesima spiral surface snails.In order to simplify the manufacture of the proposed snails them inclined surface may be formed at the expense of a pack of thin snails.Therefore, such a device (the snail) is performed from a set of thin snails with different parameters of the helix (e.g., pitch of the helix). This allows to simplify the production of such snails with different parameters, including different angles of inclination of the working surface through the use of various combinations of standardized elements (thin snails). Received snail has a stepped spiral surface (Fig. 4). 1.
