Description

Multi-way cyclone cold and heat separator

The utility model relates to a kind of multichannel cyclone cold-hot separator, belongs to technical fields such as refrigeration, air-conditioning, fresh-keeping, medical treatment.

Existing compression cyclone isolation technics, several patented technologies are also arranged both at home and abroad, the miniature vortex tube refrigerator of MX-Z type of the Soviet Union for example, the novel automobile air-conditioner system of U.S. A Sitelao company, domestic patent, for example 89213764.4 and 89212392.3 its operation principles have 2 kinds, the first is conveyed into the empty free-vortex one that forms of vortex through exchange of kinetic energy and cold and hot gas separation with subsonic speed or supersonic airstream continuously by nozzle, its shortcoming is that the temperature difference of hot and cold air is very little, efficient is also low, be difficult to realize big flow, practicality is not enough, and it two is that air inlet pipe rotation is carried out exchange of kinetic energy with compressed air through diffusion system intermittently cold air is provided, though and novel Cyclonic cold-hot separator also makes improvements, but cold air flow is still few, and refrigerating capacity is few, also is difficult to be applied to air-conditioning refrigeration system so have a narrow range of temperature, in second kind of operation principle, the short complex structure of the low rotational life of its refrigerating efficiency is huge, and noise is big, can not be used for window air conditioner, refrigerator, systems such as medical treatment.

The purpose of this utility model is that a kind of multichannel cyclone cold-hot separator will be provided, and it can overcome above-mentioned shortcoming, makes flow and temperature be applicable to the cooling or the intensification in fields such as air-conditioning system fridge freshness retaining system medical treatment more greatly.

The purpose of this utility model is achieved in that adopting a plurality of Laval nozzles to increase charge flow rate improves refrigerating efficiency.Heating pipe one end is connected with the insulated case that forms vortex chamber, the other end connects a control valve, the upper end of valve connects a flow divider again, the housing left end gland of also packing into, connect a flow divider again, gland has the through hole compressed air that communicates with the passage of flow divider to introduce vortex chamber along vortex chamber tangential direction position through the Lavalle nozzle and it is increased by subsonic speed be supersonic speed, spreading in the dextrorotation volute chamber and participating in the high speed rotation makes gas cold and hot disconnected from each other, adopting a plurality of Lavalles nozzle to be the tangential direction position along vortex disposes symmetrically, vortex chamber connects to be with nozzle connects, the multiple-series mode that parallel connection or connection in series-parallel combine, significantly improve separating property and flow, the temperature difference can be improved cooling effect by above-mentioned separator.

Now in conjunction with the accompanying drawings the structure of multichannel cyclone cold-hot separator is described in further detail.

By Fig. 1, by insulated case (8) the vortex chamber that forms (1), the left end of heating pipe (4) is connected with the screwed hole of screw thread with insulated case (8), insulated case (8) left end also has screwed hole, the gland (2) of packing in the hole, gland (2) has a through hole (9), flow divider (3) joins with gland (2), flow divider (3) also has a passage (10), this passage (10) can be connected with the through hole (9) of gland (2), control valve (6) is contained in the right-hand member of heating pipe (4), its valve body upside has a through hole (11) to communicate with the passage (12) of flow divider (5), the upper end of valve body is connected with flow divider (5), and cold air is from flow divider (3) stream, and hot gas flows out from flow divider (8).

Fig. 2 is the A-A cutaway view of accompanying drawing 1 separator, and the tangential direction position configuration of the even symmetrically cloth ground of 4 nozzles (7) along vortex chamber (1) arranged among the figure, further improves air-flow and rotates at a high speed, is convenient to cold and hot gas and shunts in order, improves the cyclone effect.Compressed Gas makes the flow velocity quickening increase from subsonic speed and is supersonic speed through Laval nozzle (7), enters at last to spread in the vortex chamber (2) to participate in rotating at a high speed, has improved the efficient of separator.

Vortex chamber (1) can be that mode in parallel or series connection also can be the multiple-series form that series and parallel combines with the connected mode of La Er nozzle (7).

When adopting parallel way, multichannel increases air flow rate, and at this moment shunting action does not all take place for flow divider (3), (5), has only cold air or hot gas to flow out respectively.

Flow divider (3) is brought into play its shunting action when adopting series connection or also the multiple-series form of series combination is freezed, and part cold air is introduced vortex chamber (1) again, draws cold gas, and at this moment flow divider (5) is only drawn hot gas.

Flow divider (5) has been brought into play shunting action when the form that adopts series connection or connection in series-parallel to combine heats, and (1) introduces vortex chamber again to part hot gas, and high temperature hot gas is drawn in (1), (2), and flow divider (3) is only drawn cold air.

Fig. 3 is the signal of parallel form, 4 nozzles (7) are contained in above the tangential direction position of vortex chamber (1) symmetrically and evenly, compressed air is introduced in from nozzle and reacts later hot gas the cyclone volute chamber (1) from left end heating pipe (4) stream, and cold air via through holes (9) is flowed out by flow divider (3).

Fig. 4 is the schematic diagram of series connection form, compressed air reacts the back and is flowed out by through hole (9) from vortex chamber (1), flow out cold air to the right through flow divider (3), and hot gas is to be flowed out by heating pipe (4), part cold air flows into the nozzle of upper right below again from two passages of flow divider (5), though continuation effect in vortex chamber is this minimum in conjunction with the little temperature of pattern flow.

Fig. 5 is and the multiply-connected mode of series combination, compressed air is introduced from the nozzle (7) of left upper end and lower end, the left and right sides, via through holes (9) and flow divider (3) be to right-hand member outflow cold air after revolving chamber (1) reaction, and a part of cold air flows out again from the passage of upper end and flows back to vortex chamber (1) again and together participate in reacting with new air once more.

Its cooling effect of the mode of Fig. 5 is better, but flow is still bigger in the mode of scheming (3) figure (5).

Compared with prior art, multichannel cyclone cold-hot separator has following advantage:

1, refrigerating capacity (or adding heat) is bigger, the efficient height, and power consumption is few.

2, volume in light weight is little, low cost of manufacture.

3, reliable operation, easy to repair.

4, can realize multiple connecting mode according to different purposes, flexible.
