Abstract
The invention discloses a structure of a flow divider. The structure comprises a flow divider body which comprises an inner flow passage, wherein the inner flow passage comprises a mixing chamber, an ejection hole, a distribution chamber and a pipe outlet, and a bubble refining device is arranged in the distribution chamber. By means of the bubble refining device, uniformity of flow dividing is ensured, and airflow sound generated during starting and liquid flow sound generated during normal operation are lowered down.
Description
Technical field
The present invention relates to a kind of air-conditioning duct assembly, relate in particular to a kind of diversion structure.
Background technology
Chinese patent CN201340150Y has proposed a kind of liquid-dividing head, this liquid-dividing head one end is provided with refrigerant entrance, the other end is provided with a plurality of tap holes, it is characterized in that: described tap hole equal and opposite in direction, be conical and be uniformly distributed, its root crosses, and forms cone shaped cavity, and this cone shaped cavity and refrigerant entrance joint are shrunk to neck, the outer imperial palace of refrigerant entrance is little, is bell mouth shape.Although this kind of current divider flow process pressure loss reduces to some extent, but do not improve in the performance aspect reduction noise, when air-conditioning start, existing current divider also has obvious liquid stream sound in the time of can producing obvious airflow noise and operation after compressor start, cause air conditioning comfortableness to decline, affect user and use.The patent that the application number that Wo Sixiang China national Department of Intellectual Property submits to is 2013205951131, a kind of current divider is also proposed, the nozzle arrangements of this current divider changes a plurality of small nozzles hole into by giant hole, but this structural flow dynamic resistance is larger, and because idle call current divider import refrigerant is gas-liquid two-phase, the flow in each small nozzle hole is subject to import refrigerant distribution influence larger, and shunting effect and noise problem still have much room for improvement.
summary of the invention
The present invention is mainly to provide a kind of diversion structure, has guaranteed the uniformity of shunting, the liquid stream sound when reducing the airflow noise producing because of starting up and normally moving.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: it comprises current divider body, described current divider body comprises inner flow passage, described inner flow passage comprises mixing chamber, spray-hole, distributor chamber and goes out pore, is provided with fining air bubbles device in described distributor chamber.When operation of air conditioner, gas-liquid two-phase refrigerant after throttling first flows into mixing chamber to be mixed, pass through afterwards nozzle ejection, refrigerant after injection is through fining air bubbles device, refrigerant is uniformly distributed, avoid the generation of larger bubble to reduce noise, and guarantee that the gas-liquid two-phase refrigerant that enters distributor chamber evenly mixes simultaneously, finally can guarantee uniformity and the better noise result of shunting.
As preferably, described fining air bubbles device is screen modules, and described screen modules comprises dictyosome.
As preferably, described screen modules also comprises holder, and described holder is annular fixed seat, and the edge of described dictyosome is connected with described holder.
As preferably, described holder is close to distributor chamber inwall.Can avoid like this fluid to walk around net-filter assembly and flow directly into distributor chamber.
As preferably, described dictyosome is convex-shaped, and dictyosome is provided with some mesh.
As preferably, described distributor chamber comprises forked chamber.
As preferably, described screen modules is arranged in described forked chamber, in forked chamber, is provided with entry, and described dictyosome stretches in the entry of forked chamber, and the cancave cambered surface of dictyosome goes out pore towards described.
Bubble disintegration device of the present invention is arranged in distributor chamber, gas-liquid two-phase refrigerant can fully mix in mixing chamber, spray-hole, distributor chamber like this, and the wire side area of dictyosome also increases greatly, flow resistance reduces further, airflow noise and liquid stream sound have obtained effectively controlling like this, and noise problem obtains larger improvement.
As preferably, in described distributor chamber, be provided with the branching block of cone shape.
As preferably, described fining air bubbles device is porous packing.
As preferably, described porous packing comprises sponge, described in go out pore and be provided with a plurality of.
The beneficial effect that the present invention brings is that the present invention has adopted fining air bubbles device, has guaranteed the uniformity of shunting, the liquid stream sound when reducing the airflow noise producing because of starting up and normally moving.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present invention;
Accompanying drawing 2 is a kind of structural representations of screen modules of the present invention;
Accompanying drawing 3 be in accompanying drawing 2 A-A cut open to a kind of structural representation.
Label declaration: 1, hand-hole; 2, mixing chamber; 3, spray-hole; 4, screen modules; 4-1, dictyosome; 4-2, holder; 5, distributor chamber; 6, go out pore; 7, branching block.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, technical scheme of the present invention is described in further detail.
Embodiment: a kind of diversion structure of the present embodiment is as shown in Fig. 1,2,3, comprise current divider body, current divider body comprises the inner flow passage setting within it, inner flow passage comprises and enters to manage the hand-hole 1 that is connected, mixing chamber 2, spray-hole 3, distributor chamber 5 and a plurality ofly go out pore 6, hand-hole 1, mixing chamber 2, spray-hole 3, distributor chamber 5 and go out pore 6 and be sequentially arranged in inner flow passage, be provided with fining air bubbles device in distributor chamber 5.
Fining air bubbles device comprises screen modules 4, and distributor chamber 5 comprises forked chamber, is provided with the branching block 7 of cone shape in distributor chamber 5, and screen modules 4 is fixed in forked chamber.
During work, gas-liquid two-phase refrigerant after throttling enters the mixing chamber 2 of current divider by hand-hole 1, then through nozzle bore, spray, refrigerant is evaporated rapidly and produce a large amount of bubbles, bubble disturbance fully mixes gas-liquid two-phase refrigerant, now the screen modules 4 in distributor chamber 5, by fining air bubbles, has effectively been improved air-flow and liquid stream sound, and the mixed uniformly gas-liquid two-phase refrigerant after refinement is assigned to equably and respectively goes out pore 6.
Below only just preferred embodiment of the present invention is described, but can not be interpreted as it is limiting the scope of the invention.The present invention is not only confined to above embodiment, and its concrete structure or shape allow to change.In a word, protection scope of the present invention should comprise those apparent conversion or alternative and remodeling to those skilled in the art.
