A kind of refrigerant distributor provided by the utility model due to separatory runner simple in structure, that do not need processed complex, therefore can adopt the red copper tubing that quality is softer, price is lower to process, thereby reduce material cost and processing cost; Simultaneously, when refrigerant distributor and separating tube when welding that is all the red copper material, the welding difficulty is little, the stifled or half stifled situation of weldering of separating tube weldering can not occur and causes separatory uneven, has improved stability.
Description of drawings
Fig. 1 is the structural representation of refrigerant distributor in prior art;
Fig. 2 is the main pseudosection of refrigerant distributor one preferred embodiment of the present utility model.
The realization of the utility model purpose, functional characteristics and advantage are described further with reference to accompanying drawing in connection with embodiment.
The specific embodiment
Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Referring to Fig. 2, refrigerant distributor one preferred embodiment of the present utility model is proposed, described refrigerant distributor integral body is cylindrical, comprise a distributor body, offer the inlet 100, separatory chamber 200 and the liquid outlet 300 that are communicated with successively in this distributor body, separatory chamber 200 inside have a separator 400, and separatory chamber 200 is separated into rectifying cavity 210 and mixed sap cavity 220 two parts, and wherein rectifying cavity 210 is near inlet 100, the close liquid outlet 300 of mixed sap cavity 220.Offer some spray holes 410 on separator 400 to be communicated with rectifying cavity 210 and mixed sap cavity 220, so that cold-producing medium is spurted into mixed sap cavity 220 from rectifying cavity 210 under pressure, the large I of spray hole 410 is decided according to the actual requirements, its shape is preferably tapered, its at the diameter of rectifying cavity 210 1 ends greater than the diameter at mixed sap cavity 220 1 ends, make cold-producing medium enter, spray from miner diameter end from bigger diameter end, further increase jet velocity and dynamics.After spurting into mixed sap cavity 220 due to cold-producing medium from rectifying cavity 210, cold-producing medium can evaporate and cause volume to increase, and the volume of therefore mixed sap cavity 220 is beneficial to the evaporation of cold-producing medium more preferably greater than the volume of rectifying cavity 210.Offer at least two fluid holes 310 after liquid outlet 300 end-encloseds, liquid outlet 300 ends also need with the separating tube welding of air-conditioner so that fluid hole 310 is communicated with separating tube.
the cold-producing medium of gas-liquid two-phase is pressed into rectifying cavity 210 endlessly by inlet 100, rectifying cavity 210 interior gather in a large number and pressurized after by the spray hole 410 on separator 400 to the interior injection of mixed sap cavity 220, the inwall of jet-stream wind at a high speed and mixed sap cavity 220 or the collision of the low velocity fluid in mixed sap cavity 220, make the air pocket in cold-producing medium break and form spray cone, minute bubbles wherein break on the top of spray cone, liquid in cold-producing medium becomes droplet, high velocity air disturbance low velocity fluid and form convection current simultaneously, make cold-producing medium stir in mixed sap cavity, thereby the cold-producing medium of gas-liquid two-phase is able to realize mixing fully in mixed sap cavity 220, become uniform fluid, be assigned to uniformly in each separating tube finally by separatory hole 310.
Because the refrigerant distributor of the present embodiment is simple in structure, do not need the separatory runner of processed complex, therefore can adopt the red copper tubing that quality is softer, price is lower to process, thereby reduce material cost and processing cost; Simultaneously, when refrigerant distributor and separating tube when welding that is all the red copper material, the welding difficulty is little, the stifled or half stifled situation of weldering of separating tube weldering can not occur and causes separatory uneven, has improved stability.
Further, separator 400 is hat-shaped, and the edge is tight against the inwall of separatory chamber 200 and near rectifying cavity 210 1 ends, protrude toward mixed sap cavity 220 directions at the middle part, and spray hole 410 is opened in the separator top.The main body of refrigerant distributor is copper tube, adds man-hour, sealing this end, then offers fluid hole 310 in copper tube one end welding one copper plate on copper plate; The separator 400 that then will offer spray hole 410 heads into its inner suitable position from the copper tube other end, because separator 400 is hat-shaped, push rod can be stretched into separator inside, and is convenient when therefore heading into, stable and be conducive to the location; Utilize ductility and the toughness of red copper material, draw at last copper tube, make it to form the large refrigerant distributor of the little middle bore of two ends bore, also further separator 400 is anchored on inside simultaneously.Thereby, improved the stability of working (machining) efficiency and product.
Further, the internal diameter of inlet 100 is less than the internal diameter of rectifying cavity 210, cold-producing medium the little inlet 100 of internal diameter interior when mobile the flow velocity elevated pressures larger, can swash when the inlet little from internal diameter 100 enters the large rectifying cavity 210 of internal diameter and penetrate in rectifying cavity 210, hang down the cold-producing medium of flow velocity in disturbance rectifying cavity 210 and form convection current, make cold-producing medium stir in rectifying cavity, thereby cold-producing medium is able to be pre-mixed in rectifying cavity 210, make refrigerant mixed get more full and uniform, cold-producing medium will be more even when being dispensed into separating tube.
Further, the internal diameter of liquid outlet 300 is less than the internal diameter of mixed sap cavity 220, cold-producing medium flows to the less liquid outlet of internal diameter 300 after fully mixing in mixed sap cavity 220, cause flow velocity and pressure to increase in the interior contraction of liquid outlet 300, then be able to be dispensed in each separating tube more rapidly, uniformly by each fluid hole 310, thereby further improved the uniformity that cold-producing medium distributes.
The red copper material that the preferred quality of the refrigerant distributor of above-described embodiment is softer, cost is lower, be conducive to process in fact also can adopt other materials according to actual needs.
The utility model proposes a kind of air-conditioner simultaneously, it comprises a refrigerant distributor, this refrigerant distributor comprises a distributor body, described distributor body comprises inlet, separatory chamber and the liquid outlet that is communicated with successively, has a separator in described separatory chamber, this separator is divided into described separatory chamber near the rectifying cavity of inlet and the mixed sap cavity of close liquid outlet, offers spray hole on described separator, offers at least two fluid holes after described liquid outlet end-enclosed.Refrigerant distributor described in the present embodiment is the related refrigerant distributor of above-described embodiment in the utility model, does not repeat them here.
Should be understood that; these are only preferred embodiment of the present utility model; can not therefore limit the scope of the claims of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
