Abstract
This invention relates to a kind of knockout of air conditioner that belongs to refrigeration field. It settles the problem of refrigerants flow-splitting unevenly, which causes the problem that heat exchanging capacity of evaporator can not fully be given to play. The said distributing cavity draws out many liquid outputting cavities. The said distributing cavity has connecting opening which is communicated with the said branched liquid outputting cavity. The center line included angle a of the said mixed cavity and liquid outputting cavity is less than 90degree. The flow jetting end of knockout uses the design of inner spherical surface. It prevents one-off directly flow-splitting. The inputted and outputted liquids are arranged at the same side of knockout. The liquid inputting straight pipe is long. The flow-splitting is carried out evenly.
Description
Technical field
The present invention relates to a kind of knockout, particularly a kind of knockout that is used for air-conditioner.
Background technology
The traditional knockout that uses in air-conditioner evaporator, its cold-producing medium liquid in-out direction unanimity is following current.In the reality, usually owing to the restriction of knockout installing space, make the feed liquor flow development length of knockout be difficult to guarantee, thereby influenced the shunting uniformity of cold-producing medium, cause the evaporimeter exchange capability of heat to be not fully exerted, directly reduced the refrigeration of air-conditioner.For the knockout that has injector head, it also is one of uneven common cause of shunting that injector head is installed the location deflection, and this problem is difficult to control aborning.
Summary of the invention
The object of the present invention is to provide a kind of knockout of air-conditioner, it is inhomogeneous to have solved cold-producing medium shunting, the problem that causes the evaporimeter heat-exchange capacity not give full play to.
The object of the present invention is achieved like this: knockout, comprise the knockout body, sprue in the knockout body and go out sap cavity, described sprue comprises hybrid chamber, distribution cavity, it first is characterised in that: a plurality of sap cavities that go out are drawn by described distribution cavity branch, described distribution cavity has the connection opening that sap cavity communicates that goes out with described branch, described hybrid chamber and describedly go out the center line angle a of sap cavity less than 90 degree.
Its second is characterised in that described sprue is made up of two parts: a part is hybrid chamber, and described hybrid chamber is a cylindrical cavity; Another part is a distribution cavity, extends upward the part Internal Spherical Surface cavity that forms for described hybrid chamber cylinder; Described hybrid chamber and distribution cavity form the warhead shape cavity in described knockout body.
Its 3rd is characterised in that described sprue is made up of two parts: a part is hybrid chamber, and the cylinder cavity that described hybrid chamber is not waited by two sections diameters is formed ladder barrel shape cavity; Another part is a distribution cavity, and described distribution cavity is that described hybrid chamber path cylinder extends upward the part Internal Spherical Surface cavity that forms.
Its 4th is characterised in that described to go out sap cavity be the equal diameter cylindrical cavity.
Its 5th is characterised in that described to go out sap cavity be that the cylinder cavity that two sections diameters do not wait is formed ladder barrel shape cavity.
Its 6th is characterised in that described distribution cavity is arranged in the knockout chamber body, and goes out the sap cavity arc transition.
Advantage of the present invention is: (one), knockout inner chamber jet end adopt the Internal Spherical Surface design, and natural arc transition has been avoided disposable direct shunting, and cold-producing medium does not have bound process, and liquid stream can not produce airflow noise; (2), can adjust the injection stream distance, dwindled the fluid issuing diffusion angle, reduce dischargeable capacity in the chamber, increased inside static pressure; (3), not reducing of pipeline, not throttling of fluid issuing, reduced the noise that produces because of throttling; (4), the liquid in-out of knockout is positioned at homonymy, the length of feed liquor straight tube is long, shunting evenly; (5), compact conformation, flexible for installation.

The specific embodiment
Embodiment one:
Shown in Figure 2, the invention provides a kind of knockout of air-conditioner, described knockout comprises knockout body 1, sprue 40 in the knockout body 1 and go out sap cavity 30, described sprue 40 comprises hybrid chamber 2, distribution cavity 3, described distribution cavity 3 branch is radially drawn a plurality of sap cavities 30 that go out, and described distribution cavity 3 has the connection opening 6 that sap cavity 30 communicates that goes out with described branch, described hybrid chamber 2 and describedly go out the angle a of sap cavity 30 less than 90 degree.Described sprue 40 is made up of two parts: a part is hybrid chamber 2, and the cylinder cavity that described hybrid chamber 2 is not waited by two sections diameters is formed ladder barrel shape cavity; Another part is a distribution cavity 3, and described distribution cavity 3 extends upward the part Internal Spherical Surface cavity that forms for described hybrid chamber 2 path cylinders.According to actual needs, going out sap cavity 30 can be set to the identical cylindrical cavity of diameter or be set to the cylinder cavity composition ladder barrel shape cavity that two sections diameters do not wait.Go out the cylinder cavity that sap cavity 30 do not wait by two sections diameters in the present embodiment and form ladder barrel shape cavity.
As shown in Figure 1, be the vertical view of a kind of embodiment of the present invention, the number of the fluid hole 5 of this knockout is 8;
Described knockout can directly connect corresponding refrigerant tubing, carries out the shunting of cold-producing medium.One injector head 15 also can be set in the described knockout carry out the shunting of cold-producing medium;
As Fig. 4, shown in Figure 6, injector head 15 assigns in the sprue 40 of knockout body 1, because injector head 15 is a step structure, after hybrid chamber 2 and distribution cavity 3 cooperate, injector head 15 probes into distribution cavity 3, and has formed the cavity of crescent section in distribution cavity 3.Cold-producing medium enters from the runner 11 of injector head 15, spray into the cavity of the crescent section in the distribution cavity 3 again from its spray-hole 16, again by distribution cavity 3 with go out the connection opening 6 that sap cavity 30 communicates and enter out sap cavity 30, each runner of present embodiment makes cold-producing medium gas, liquid two-phase fully mix, thereby reaches the purpose of even shunting, energy-saving and noise-reducing.
Present embodiment adopts eight tunnel shuntings, and eight road fluid holes 5 evenly distribute on knockout body 1.
The distribution cavity of present embodiment can make the knockout body 1 inner Internal Spherical Surface cavity that forms, flow into again after cold-producing medium compiles in this cavity and respectively branch out sap cavity 30, because the change of fluid state can effectively solve the problem that gas-liquid is respectively pasted effluent, makes shunting more even.
Embodiment two:
Shown in Figure 3, different being of present embodiment and embodiment one maximum:
The hybrid chamber 2 of sprue described in the present embodiment 40 is isodiametric cylinder rather than the stepped cylinder be made up of two sections anisodiametric cylinders.
As Fig. 5, shown in Figure 7, injector head 15 assigns in the sprue 40 of knockout body 1, the distribution cavity 3 that cold-producing medium enters knockout body 1 from the spray-hole 16 of injector head 15 enters out sap cavity 30 by distribution cavity 3 with going out the connection opening 6 that sap cavity 30 communicates again, realizes the shunting purpose of cold-producing medium.
Above-mentioned explanation is not to be limitation of the present invention; the present invention also is not limited to above-mentioned giving an example, and those skilled in the art are in essential scope of the present invention; the variation of making, remodeling or other do not change the replacement of essential scope, belong to protection scope of the present invention yet.
