The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, present embodiment comprises columnar main body 2.Visible from Fig. 4 and Fig. 5, the sealing of main body 2 right-hand member end faces, main body 2 left end end faces are provided with 3 shunt and portal 1; Also visible from figure; The left side of main body 2 is to the protruding inclined-plane of main center; 3 shunt are portalled and 1 are distributed near the circumferential edge of left side, and 1 the center line of portalling along separate routes is with respect to the center line outward inclining of main body 2, are convenient to each shunt tubes like this and are installed on each and portal along separate routes on 1.The inner chamber of main body 2 is shunting cavity 3, portal along separate routes 1 with shunting cavity 3 UNICOMs.From figure, can see; Be positioned on the body wall of main body 2 blind ends and have refrigerant ingate, a tangential 4; The center line of refrigerant ingate 4 is vertical but non-intersect with the center line of main body 2; Parallel with the inwall tangent line of shunting cavity 3 near also, the refrigerant tangential in the feed pipe that inserts in the refrigerant ingate is got in the shunting cavity 3.Main body 2 are one one end diameters greater than other end diameter be toy trumpet shape circle tube member, the cross-sectional area that is to say shunting cavity 3 is in i.e. increase gradually on 1 the direction of portalling along separate routes on the refrigerant flow direction.
For better mixing, the inwall of shunting cavity 3 also can be processed into screw thread form, with the uniformity coefficient of further reinforcement gas-liquid two-phase refrigerant mixing.
During operation of air conditioner, gas-liquid two-phase refrigerant at a high speed gets into from tangential, shunting cavity 3 right side shown in Figure 4, forms the helical flow that moves right along shunting cavity 3 inwalls; Gas-liquid is fully mixed under action of centrifugal force, because shunt body cavity 3 cross sections area on the refrigerant flow direction increases gradually, flow velocity reduces simultaneously; Static pressure raises; The part gas phase refrigerant becomes the liquid phase refrigerant mutually, in uniform pressure field of left bottom formation of shunting cavity 3, under same pressure effect; Refrigerant is evenly distributed in the middle of its corresponding stream from 1 outflow of portalling along separate routes.Also visible from Fig. 4, the left side in shunting cavity 3 is centered close to shunt portals near 1, and the processome of a vertebra shape is arranged, and this vertebra shape processome can be used for the water conservancy diversion of refrigerant.
Adopt the shunt body of the utility model, feed pipe is comparable traditional littler.Under same refrigerant mass flow, the speed that gets into shunt body cavity is bigger, and the intensity of its screw is also big more, and gas-liquid mixed gets more even, and shunting effect is better.The internal diameter of import feed pipe is bigger than orifice in tradition shunt body; The speed of cold-producing medium is lowered in the forward position, aperture; Biphase gas and liquid flow through the time lack of homogeneity (be prone to cause two be separated), and the utility model can be avoided being separated in the import feed pipe.
The utlity model has better separatory effect through experiment showed,, separatory is more even; Refrigerating capacity increases; Do not receive the influence of import mass velocity and steam mass dryness fraction, the power of its mixing is centrifugal force, thereby the inclination angle when installing also has only faint influence to its separatory effect.Install with the also fine small space that is applicable to of roughly 90 degree interlaced arrangement that portals along separate routes the refrigerant ingate.
