Description

Vortex tube

Technical field

The utility model relates to attemperating unit, but particularly about a kind of independent operation, novel structure and vortex tube easy to use.

Background technology

As shown in Figure 1, it is traditional vortex tube 1, be provided with a room 3 in one body 2, one supplies gases at high pressure to enter the inlet 4 of room 3, one cooling gas is by the cold air outlet 5 of discharging in the room 3, and a long tube 6 that extends by body 2, the end of long tube 6 is provided with a heat outlet 7, and one controlledly heats the control valve 8 that gas exports 7 sizes.

Traditional vortex tube 1 all needs by a compressor (figure does not show) gases at high pressure to be poured in the room 3 by inlet 4, in room 3, produce behind the eddy current along long tube 6 to the right in the shape of a spiral shape advance, when arriving heat outlet 7, the controlled valve 8 of a part of gas stops and refluxes left, remaining gas is discharged to the external world via control valve 8, the gas of Liu Donging is positioned at skin to the right, the gas of Hui Liuing is then for being positioned at internal layer left, the energy exchange meeting of the two heats the gas that flows to the right, make the gas cooling that refluxes simultaneously left, hereat higher by the gas temperature of heat outlet 7 discharges, the gas temperature of being discharged by cold air outlet 5 is then lower.

Because vortex tube 1 need not can be reached the effect of controlling temperature by cold coal, its application is day by day extensive, but traditional vortex tube can't independent operation, must an external air compressor pressure-air is poured in the room 3, convenience is not good enough during use, and general compressor volume is huge, how under the condition of limited of space vortex tube and compressor bank to be fitted together, and becomes troubling problem.

The innovation and creation content

But the purpose of this utility model provides a kind of vortex tube of independent operation, and it is simple for structure light and handy, and is very convenient during use.

For achieving the above object, the utility model is taked following technical scheme: a kind of vortex tube, it is characterized in that, it includes: a body, one control valve, one motor, and a turbine, wherein said body interior hollow and form a room, described body is provided with an inlet, one cold air outlet, and a long tube, an end of described long tube is communicated with described room, and the other end is provided with a heat outlet, described control valve is arranged on described heat outlet place, and described motor is arranged in the room of described body, and it has an axle, described axle hollow and have an axis hole, described axis hole is communicated with described cold air outlet, and described turbine is arranged on the described axle and is positioned at the room of described body, and described turbine tool also is provided with a centre bore that is communicated with described axis hole.

Description of drawings

Fig. 1 is the structural representation of conventional vortex tube.

Fig. 2 is the structural representation of the utility model one preferred embodiment.

The specific embodiment

For structure of the present utility model and characteristics are described, lift following preferred embodiment and conjunction with figs. now and be described in detail as follows:

As shown in Figure 2, be the vortex tube 10 that the utility model one preferred embodiment is provided, it includes a body 20, one control valve 30, one motors, 40, one turbines 50 and instlated tubulars 58.

It is cylindric that body 20 generally is, its inner hollow and form a stepped annular room 22, can be divided into a large-diameter portion 221 and a minor diameter part 222, body 20 is provided with an inlet 24, one cold air outlets 25, an and long tube 26, the left end 27 of long tube 26 is communicated with room 22, and right-hand member then forms a heat outlet 28, the long tube 26 outer instlated tubulars 58 that also are arranged with, instlated tubular 58 and long tube 26 intervals one preset distance, it can reduce long tube 26 and extraneous heat exchange.

Control valve 30 is arranged on heat outlet 28 places, adjusts the size of heat outlet 28, can control the discharge rate of hot gas on the one hand, has the effect of noise when reducing exhaust on the other hand.

Motor 40 is installed in the minor diameter part 222 of room 22, it has an axle 42 of being extended towards large-diameter portion 221 by room 22 minor diameter parts 222, axle 42 is for hollow and have an axis hole 43, its internal diameter is less than the internal diameter of long tube 26, and axle 42 is arranged on the same axle center with long tube 26, in addition, the left end of axis hole 43 is communicated with cold air outlet 25.

Turbine 50 is arranged on the axle 42, and be positioned at the room 22 of body 20, accurately, turbine 50 is positioned at the bearing of trend of the central shaft 241 of inlet 24, turbine 50 has a centre bore 52 that is communicated with axis hole 43, centre bore 52 is gradually opens taper, but the maximum diameter of hole of centre bore 52 is less than the internal diameter of long tube 26.

During operation, starter 40 makes axle 42 drive turbine 50 rotations, to air be entered in the large-diameter portion 221 of room 22 with a predetermined pressure via inlet 24, air is subjected to the disturbance of turbine 50 simultaneously, the eddy current of rotation at a high speed will be formed, flow to the right along long tube 26, because the internal diameter of long tube 26 is bigger than the axis hole 43 of the centre bore 52 of turbine 50 and axle 42, therefore, eddy current can not entered by the centre bore 52 of turbine 50 in the axis hole 43 of axle 42, when eddy current flows in long tube 26, because centrifugal action will make eddy current paste tube wall and advance, form a hot gas eddy current 60, hot gas eddy current 60 central authorities then stay undisturbed passage; When hot gas eddy current 60 arrives heat outlet 28, owing to be controlled the current limliting of valve 30, only some hot gas eddy current 60 discharges, all the other eddy current then reflux via centre gangway, its direction of rotation is identical with hot gas eddy current 60, form a cold air eddy current 62, energy (heat) exchange in cold air eddy current 62 and the hot gas eddy current 60 intersection processes will make hot gas eddy current 60 heat, make 62 coolings of cold air eddy current simultaneously, when cold air eddy current 62 continues to flow left, to enter the axis hole 43 of axle 42 via the centre bore 52 of turbine 50, discharge by cold air outlet 25 at last.

By this, vortex tube 10 can utilize self motor 40 and turbine 50 that outside air is sucked, another air compressor of need not arranging in pairs or groups during use, but the advantage that not only has independent operation, and overall volume more can effectively reduce, and is convenient to assembling, particularly under the condition of limited of space, more can highlight effect of the present utility model, effectively improve the shortcoming of conventional vortex tube structure, thereby reach the purpose of this utility model.
