Abstract
The invention relates to a retractable archimedes type line vortex tube nozzle which is characterized by comprising air inlets, a nozzle outside passage, a passage baffle plate, nozzle passages, a nozzle vortex chamber and peripheral baffle plates, wherein the nozzle outside passage is equally divided into two segments by the passage baffle plate; each segment of the nozzle outside passage is internally provided with the two nozzle passages; and the two semicircular peripheral baffle plates are arranged on the periphery of the nozzle outside passage and form the two air inlets. The nozzle passages adopt retractable archimedes type line design and double-layer passage design; in addition, the retractable archimedes type line vortex tube nozzle not only can enhance the heat exchange efficiency of inner air and outer air inside the vortex chamber by increasing the rotational speed of air in the vortex chamber through the retractable archimedes line type passages, but also can prevent the condition that the flow quantity and the pressure of compressed air are non-uniformly distributed on the nozzle passages because a single air inlet is adopted, thereby finally achieving the purpose of enhancing refrigerating efficiency.

Technical field
The invention belongs to refrigerating field, be specifically related to a kind of contraction type archimedes type line vortex pipe nozzle.
Background technology
Vortex tube is a kind of energy separation device, the normal temperature air of certain flow and pressure can be separated into a part of cold air and a part of hot-air.Vortex tube mainly partly is made up of minor air cell, nozzle, heat pipe, cold junction orifice plate, control valve etc.During work, compressed air feeds the minor air cell earlier, because the guide effect of nozzle flow channel, air-flow is rotating the hot gas end that flows to vortex tube with high speed, part air communication is crossed control valve and is flowed out, after another part gas is blocked, with same rotating speed reverse rotation, and flow to the cold air end of vortex tube at former air-flow inner ring.In this process, two bursts of air-flow generation heat exchanges, interior ring air-flow becomes terribly cold, and from the cold air end outflow of vortex tube, it is awfully hot that the outer shroud air-flow then becomes, from the hot gas end outflow of vortex tube.Wherein nozzle is the critical component of energy separation, and it can be converted into the speed energy with the pressure of Compressed Gas, and structure of nozzle directly affects the quality of refrigeration performance.
At present, conventional nozzle has linear pattern runner nozzle and spiral of Archimedes type runner nozzle, linear pattern runner nozzle section figure as shown in Figure 1, spiral of Archimedes type runner nozzle section figure as shown in Figure 2, be characterized in relatively simple for structure, but the lifting that enters the air velocity in the minor air cell is being subjected to certain restriction, so its refrigerating efficiency is relatively low.In the conventional vortex tube, compressed air enters into the minor air cell by an inlet, is unfavorable for that compressed air is distributed to the inlet of each nozzle flow channel uniformly, therefore can cause bigger energy loss, influences its refrigerating efficiency.
Summary of the invention
The objective of the invention is to propose a kind of contraction type archimedes type line vortex pipe nozzle, promote air, thereby improve the refrigerating efficiency of vortex tube by the rotary speed behind the nozzle; Make compressed air enter the porch that can be evenly distributed on each runner of nozzle behind the nozzle of vortex tube, reduce the loss that air pressure and flow distribution inequality cause, improve refrigerating efficiency.
A kind of contraction type archimedes type of the present invention line vortex pipe nozzle, see accompanying drawing 3 and accompanying drawing 4, this nozzle includes gas port 2, the outside runner 3 of nozzle, runner baffle plate 4, nozzle flow channel 1, nozzle minor air cell 5 and outer surrounding baffle 6, it is characterized in that, the outside runner 3 of nozzle is divided into two sections by runner baffle plate 4, in every section outside runner 3 of nozzle two nozzle flow channels 1 are arranged, two semicircular outer surrounding baffles 6 are arranged on the periphery of outside runner 3, and form two air intakes 2, compressed air from the outside is at first entered respectively in the outside runner 3 by two air intakes 2, and then enter nozzle minor air cell 5 by nozzle flow channel 1 and form eddy current, this nozzle has reduced the loss that compressed-air actuated flow and pressure are caused in each nozzle flow channel punishment cloth inequality.
Wherein, air intake 2 is 90 ° of distributions with the position of runner baffle plate 4 around the center of circle;
Wherein, nozzle flow channel 1 adopts the design of contraction type Archimedes line style, and its design process is seen accompanying drawing 5 and accompanying drawing 6.Curve 6 is original archimedes curve, satisfies formula:
x=aθsinθ
y=aθcosθ(0≤θ≤2π)
Be constant wherein for a.Nozzle flow channel curve of the present invention (curve 7) be by curve 6 around its central point rotate to an angle (the contraction angle that the size of institute's anglec of rotation will satisfy the nozzle flow channel of nozzle flow channel is 5 °~10 °) form, postrotational curve can form the nozzle flow channel curve through finishing.
A kind of contraction type archimedes type of the present invention line vortex pipe nozzle, its advantage is:
(1) nozzle flow channel adopts contraction type Archimedes molded lines, and after compressed air entered into the minor air cell, this nozzle can promote the speed of air rotation greatly, therefore can promote the heat exchange efficiency of ectonexine gas in the minor air cell, and then improves refrigerating efficiency.
(2) nozzle adopts double-layer channel, comprises outside runner of nozzle and nozzle flow channel.
(3) this nozzle adopts two air intakes, by baffle plate the outside runner of nozzle is divided into two sections, every section outside runner communicates with the nozzle flow channel of equal number, like this, the compressed air uniform distribution that enters into nozzle can be given each runner of nozzle, reduce the loss that air pressure and flow distribution inequality cause, improve refrigerating efficiency.
