Description

The novel vortex cooler of industry enclosure

Technical field

The utility model patent provides a kind of improved industry enclosure vortex cooler.

Background technology

Present widely used industry enclosure vortex cooler, after general employing compressed air enters nozzle expansion, in the cylindrical shape minor air cell, form free vortex flow, be introduced into the heat pipe section of minor air cell's one side, in heat pipe forward in the flow process, the internal layer gas flow temperature reduces gradually by the vortex flow air-flow, and the outer gas flow temperature raises, until being installed in heat pipe other end needle-valve adjuster, eddy current stagnation.The separating effect of hot and cold air in the heat pipe is regulated in the gap of metering pin valve adjuster and heat pipe.The interstitial row of high temperature gas flow process needle-valve adjuster and heat pipe is to atmosphere, and cold airflow produces axial flow, under the pressure of self promotes, backflows to the minor air cell, is drawn towards the cold pipe of opposite side of minor air cell then.The cold air diffluence refrigerating industry rack that flows out through cold pipe etc. needs the equipment, device of cooling etc.

Above-mentioned vortex cooler, the effect that produces eddy current owing to compressed air behind the cylindrical shape minor air cell is general, and refrigerating efficiency is low; The effect that the elimination eddy current of needle-valve adjuster separates with hot and cold air is not good enough; High temperature gas flow directly discharges, and has polluted working environment; Cold leg directly inserts in the industry enclosure, does not form the air-flow loop, has influenced the cooling-down effect of vortex cooler.

Summary of the invention

The purpose of this utility model is to provide a kind of improved industry enclosure vortex cooler, by improving the separating effect that compressed air forms the vortex quality of eddy current and improves hot and cold air, improves refrigerating efficiency; By changing the approach that moves towards of thermal current, reduce the temperature of discharging thermal current, improve the working environment of vortex cooler; Utilize adjunction cold airflow conduit in rack, to form large-scale cold airflow loop, make uniformity of temperature profile in the rack, improved cool effect.

The utility model is achieved in that with Archimedes spiral type minor air cell and substitutes the cylinder type minor air cell, improves the vortex quality, and uses the taper prevention blocking device to improve the separating effect of refrigerating efficiency and hot and cold air; The heat pipe section adopts the internal and external casing structure, allows thermal current through the taper prevention blocking device, and the heat pipe section of flowing through inner and outer pipes is discharged behind the space, to reduce the thermal current discharge temperature, improves working environment; Cold leg adopts the internal and external casing structure, prolongs the pipe range of pipe in the cold leg and increases the outlet of rack thermal current at the cold leg outer tube, thereby form large-scale cold airflow loop in industry enclosure, reaches the ideal uniform cooling-down effect.

Description of drawings

Be further described below in conjunction with the structure of accompanying drawing the utility model patent:

Fig. 1 is that the structure of the utility model vortex cooler is formed profile.

Fig. 2 is an Archimedes spiral type minor air cell profile in the utility model vortex cooler.

Fig. 3 is the structural representation of taper prevention blocking device in the utility model vortex cooler.

The specific embodiment

Referring to Fig. 1, wherein, 1 is cylindricality compressed air inlet nozzle, 2 is Archimedes spiral shape minor air cell, 3 are the thermal current outlet, and 4 is pipe in the heat pipe section, and 5 is heat pipe section outer tube, 6 are the taper prevention blocking device, 7 is the adjusting nut that is arranged on the taper prevention blocking device 6 on outer segment 5 tops, and 8 is the cold leg outer tube, and 9 is pipe in the cold leg, 10 is the external screw thread of cold leg outer tube 8, and 11 provide the outlet of rack hot gas for outer tube 8.When compressed air enters Archimedes spiral type minor air cell 2 from nozzle 1, referring to Fig. 2, utilize Archimedes spiral die cavity body, the compressed air of the feasible nozzle 1 of flowing through forms the axial higher eddy current of vortex quality, introduce pipe 4 in the heat pipe section, eddy current is pasting inwall and vortex flow, acutely rubs with pipe 4 inwalls in the heat pipe section, cause eddy current outer gas flow temperature to raise thus, the internal layer gas flow temperature reduces.Because the vortex quality of air-flow is higher, corresponding refrigerating efficiency is significantly improved compared with the refrigerating efficiency that forms free vortex flow in the cylinder type minor air cell.Adjusting nut [7] can cone governor shape prevention blocking device 6 and the heat pipe section in gap between the pipe 4, referring to Fig. 3, make the hot and cold air that flows along swirl direction effectively to separate, thermal current after the separation in taper prevention blocking device 6 enters the heat pipe section, manage 4 and outer tube 5 between, direction shown in thick arrow, discharge from thermal current outlet 3, the temperature the when hot stream temperature of this moment separates reduces greatly, has improved the working environment of vortex cooler.Meanwhile, the cold airflow that forms in the pipe 4 in the heat pipe section forms inverted draft in the pipe 4 in the heat pipe section under the effect of taper prevention blocking device 6, backflow to the minor air cell under self pressure effect, direction flows to and manages 9 in the cold leg shown in thin arrow, enters industry enclosure again.The screw thread 10 of cold leg outer tube 8 is used for the installation that is threaded between this refrigerator and the industry enclosure.When the industry enclosure volume is big, can be according to layout in the rack, pipe 9 adjunctions one cold airflow conduit in the cold leg, and make conduit outlet away from thermal current outlet 11, so just can form large-scale air-flow loop in the inner space of industry enclosure, the heat outlet 11 of thermal current on cold leg outer tube 8 in the industry enclosure discharged, reach ideal uniform cooling-down effect in the industry enclosure.

The utility model vortex cooler has following advantage: low noise, pollute little; No movable part, compact conformation is convenient to install, and is non-maintaining.Be specially adapted to precision instrument and equipment and the refrigeration requirement that requires occasions such as the little industry enclosure of cold scope, device.
