Specific embodiment
The air-conditioning and its knockout of the embodiment of the present invention, the description of the embodiment of the present invention are described referring to Fig. 1 and Fig. 2
In, "front", "rear", " on ", D score, " top ", " bottom ", " interior ", the orientation of the instruction such as " outward " or position relationship be based on accompanying drawing institute
The orientation or position relationship for showing, are for only for ease of the description present invention and simplify description, rather than the dress for indicating or implying meaning
Put or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to limit of the invention
System.
Fig. 1 is the structural representation of knockout according to an embodiment of the invention, and Fig. 2 is cuing open for knockout shown in Fig. 1
View.As depicted in figs. 1 and 2, a kind of knockout for air-conditioning is the embodiment of the invention provides, system is illustrated with arrow in figure
The flow direction of cryogen.
Knockout includes liquid-dividing head 100, dividing plate 400, feed tube 200 and multiple isocons 300.Wherein, in liquid-dividing head 100
A point of sap cavity 101 is defined, feed tube 200 divides sap cavity 101 and be fixed on liquid-dividing head 100 from the bottom insertion of liquid-dividing head 100,
Multiple isocons 300 divide sap cavity 101 and are fixed on liquid-dividing head 100 from the top insertion of liquid-dividing head 100.Knockout is used to be arranged on
In refrigeration system, wherein feed tube 200 is used to connect throttling arrangement, and each isocon 300 is used to connect each point of evaporator
Zhi Liulu.Enter a point sap cavity 101 through feed tube 200 from the gas-liquid two-phase cold-producing medium of throttling arrangement outflow, filled in point sap cavity 101
After point deceleration buffer again uniform divided flows to multiple isocons 300 so that each branch flow passage of uniform divided flows to evaporator, with most
The big exchange capability of heat for playing evaporator.
In knockout processing, storage, transport or air-conditioning assembling process, isocon 300 is located at the outside of liquid-dividing head 100
Part can usually be subject to the external force of miscellaneous part, and isocon is easily deformed or bent, caused under external force
The bearing of trend that it is located at the part inside point sap cavity 101 deviates preset direction, causes the angle produced between multiple isocons 300
Spend and produce deviation, so as to the flow for causing the refrigerant for entering each isocon 300 produces deviation, finally bring shunting inequality
Problem.To avoid this problem from occurring, the embodiment of the present invention is especially provided with dividing plate 400 in point sap cavity 101.As shown in Fig. 2 every
Plate 400 is fixed in point sap cavity 101, and has multiple perforates 410 thereon.Each isocon 300 passes through a perforate 410, with
Make the lower end of the divided flow method pipe 300 of perforate 410.The part for being so located at the outside of liquid-dividing head 100 in isocon 300 is extruded by external force
Or during bending, the part inside liquid-dividing head 100 is smaller by being influenceed, and still can keep original extension attitude, will not
Occur inclining or flat pipe.The quantity of dividing plate 400 can be one, or multiple, so that the position of isocon 300 is more steady
Gu.
In certain embodiments, as shown in Fig. 2 can make dividing plate 400 that sap cavity 101 will be divided to be divided into up and down the two of mutual isolation
Part, makes to enter isocon 300 after entering the lower part of point sap cavity 101 from the refrigerant of the outflow of feed tube 200, without entering
Enter the upper part of point sap cavity 101, it is to avoid the refrigerant partly flowed downward from point sap cavity 101 has influence on the bottom of point sap cavity 101
The pressure distribution of the refrigerant for dividing, causes the pressure of the porch of each isocon 300 uneven, influence uniform divided flows occur.
In certain embodiments, as shown in Fig. 2 it is preferred that making dividing plate 400 and liquid-dividing head 100 be using integral forming process system
Into single piece, to omit the assembly technology of dividing plate 400 and liquid-dividing head 100.
In addition, in the conventional venturi knockout of prior art, refrigerant is directly entered each and goes out liquid inclined hole from inlet opening,
Each goes out liquid inclined hole angle easily because machining accuracy not enough produces relatively large deviation, the problem uneven so as to shunting occur.And this hair
Bright embodiment can then avoid this problem from occurring.
In certain embodiments, as shown in Fig. 2 multiple isocons 300 are extended parallel to each other, and prolonging for dividing plate 400 is made
Direction is stretched perpendicular to isocon 300, in order to the processing of perforate 410.
Further, it is preferable to multiple isocons 300 and feed tube 200 is vertically extended, to eliminate refrigerant
Gravity negative effect that uniform divided flows are produced.It is enhancing uniform divided flows effect, can also further makes multiple isocons 300
Axis is distributed in a face of cylinder for the axle centered on the axis of feed tube 200.
Compared to the scheme that multiple isocons 300 and feed tube 200 clamp acute angle, make isocon 300 and feed tube 200 equal
Vertically extending can also facilitate the assembling of isocon 300 and feed tube 200.Because in production practices, it is ensured that Duo Geguan
Road is parallel to each other than clamping multiple pipelines, and identical acute angle is easily achieved and precision is easier to ensure that.
Further, it is preferable to make the lower end of whole isocons 300 be in sustained height position, make the upper end of feed tube 200
Higher than the lower end of isocon 300.After refrigerant can so flowed out through feed tube 200, dividing plate 400, pressure drop are first sprayed at a high speed
It is low, after sufficiently buffering is completed in point sap cavity 101, each isocon 300 is entered back into, more preferable uniform divided flows effect can be reached
Really.The refrigerant from the outflow of feed tube 200 is avoided to be injected directly into part isocon 300, it is easy to cause entering for each isocon 300
There is deviation in mouth pressure, the problem for bringing shunting uneven.
In certain embodiments, as shown in Fig. 2 liquid-dividing head 100 may include circular top wall 110, Upper cylindrical wall 120, cut
Tapered wall 130 and lower cylindrical wall 140.Wherein, foregoing multiple isocons 300, top circle are installed in circular top wall 110
Post jamb 120 is extended downwardly from the edge of circular top wall 110, and frusto-conical wall 130 is extended downwardly from the lower edge of Upper cylindrical wall 120
And it is tapered to center, lower cylindrical wall 140 is extended downwardly from the lower edge of frusto-conical wall 130, and lower cylindrical wall 140 be enclosed within into
The outside of liquid pipe 200.Preferably, arc transition can be used between circular top wall 110 and Upper cylindrical wall 120, to mitigate refrigeration
The loss coefficient of agent.
In some alternate embodiments, feed tube 200 and lower cylindrical wall 140 can be made to be formed in one structure, with letter
Change the manufacturing process of knockout.
Another aspect of the present invention provides a kind of air-conditioning.Air-conditioning carries out freezing/making using vapor-compression refrigerant cycle system
Heat, compressor that it is connected using pipeline, condenser, throttling arrangement, described in evaporator and any of the above embodiment
Knockout.The connection throttling arrangement of feed tube 200 of knockout, each isocon 300 connects each branch flow passage of evaporator, with
The gas-liquid two-phase cold-producing medium uniform divided flows that will be flowed out from throttling arrangement lift changing for evaporator to each branch flow passage of evaporator
Hot property.
So far, although those skilled in the art will appreciate that detailed herein have shown and described multiple of the invention and show
Example property embodiment, but, without departing from the spirit and scope of the present invention, still can be direct according to present disclosure
It is determined that or deriving many other variations or modifications for meeting the principle of the invention.Therefore, the scope of the present invention is understood that and recognizes
It is set to and covers all these other variations or modifications.
