Description
Technical field
The utility model relates to a kind of air-conditioner, relates in particular to a kind of air-conditioning refrigerant current equalizer.
Background technology
The uniform distribution of air-conditioning refrigerant is the constantly problem of research of heat exchanger producer always, and the uniform distribution of cold-producing medium also is the principal element that influences air-condition heat exchanger efficient, particularly to the many heat exchangers of pipe row's number.In the prior art, the cold-producing medium of air-conditioner is input to the heat exchanger tube of a lot of horizontally-arrangeds that are provided with in the heat exchanger by copper tube, because gravity effect, cold-producing medium is easy to generate the heat exchanger bottom after entering heat exchanger tube the cold-producing medium of heat exchanger tube is many, and the few lamination of top heat exchanger tube cold-producing medium, can cause the utilization rate of heat exchanger top heat exchanger tube very low, cause the heat exchange efficiency of heat exchanger integral body lower.Simultaneously this lamination also can cause heat exchanger the degree of superheat of top heat exchanger than higher, the degree of superheat of bottom heat exchanger tube is lower, the degree of superheat of heat exchanger integral body is difficult to control like this.
Summary of the invention
The utility model provides a kind of air-conditioning refrigerant current equalizer, and it can improve the whole heat exchange efficiency of air-condition heat exchanger, reduces the degree of superheat of heat exchanger integral body.
The technical solution of the utility model is: a kind of air-conditioning refrigerant current equalizer, described air-conditioning comprise pipeline and the heat exchanger of importing cold-producing medium, are provided with a plurality of heat exchanger tubes in the heat exchanger; Described current equalizer comprises, cylinder body and distributor; The inlet of described cylinder body is connected with described pipeline, and outlet is connected with described distributor; Described distributor is provided with a plurality of capillaries, and this capillary is inserted in the described heat exchanger tube.
Air-conditioning refrigerant current equalizer of the present utility model, by being set, can the cold-producing medium that enter in the cylinder body evenly be mixed cylinder body, the distributor left and right sides forms pressure differential under the effect of compressor of air conditioner, even so mixed cold-producing medium can distribute and flow in the capillary that is provided with on the distributor, and then cold-producing medium is evenly distributed in the heat exchanger tube of heat exchanger, make the cold-producing medium of heat exchanger tube of heat exchanger top and the bottom evenly distribute, lamination can not occur, improve the heat exchange efficiency of heat exchanger integral body.Because cold-producing medium is evenly distributed in the heat exchanger tube of heat exchanger, and the degree of superheat of heat exchanger top and the bottom heat exchanger tube is relatively more consistent like this, so just be easy to control the degree of superheat of heat exchanger integral body simultaneously.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done a detailed elaboration.
Air-conditioning refrigerant of the present utility model comprises that with current equalizer as Fig. 1, cylinder body 1 and distributor 5, this air-conditioning comprise pipeline 3 and the heat exchanger of importing cold-producing medium, are provided with the heat exchanger tube 8 of a plurality of horizontally-arrangeds in the heat exchanger; The inlet of cylinder body 1 is connected with pipeline 3, and outlet is connected with distributor 5; Distributor 5 is provided with a plurality of capillaries 9, and this capillary 9 is inserted into 8 li of heat exchanger tubes.Described pipeline 3 can be a copper tube in concrete the application.
By the cold-producing medium after the throttling, enter pipeline 3, drain in the cylinder body 1 by pipeline 3, in cylinder body 1, mix, under the effect of compressor of air conditioner, the distributor left and right sides forms pressure differential, and the cold-producing medium that mixes drains in each capillary 9 that is provided with on the distributor by distributor 5, and then cold-producing medium can be drained into more uniformly 8 li of each heat exchanger tubes of heat exchanger.
This shows, air-conditioning refrigerant current equalizer of the present utility model, by being set, can the cold-producing medium that enter in the cylinder body evenly be mixed cylinder body, the distributor left and right sides forms pressure differential under the effect of compressor of air conditioner, even so mixed cold-producing medium can distribute and flow in the capillary that is provided with on the distributor, and then cold-producing medium is evenly distributed in the heat exchanger tube of heat exchanger, make the cold-producing medium of heat exchanger tube of heat exchanger top and the bottom evenly distribute, lamination can not occur, improve the heat exchange efficiency of heat exchanger integral body.Because cold-producing medium is evenly distributed in the heat exchanger tube of heat exchanger, and the degree of superheat of heat exchanger top and the bottom heat exchanger tube is relatively more consistent like this, so just be easy to control the degree of superheat of heat exchanger integral body simultaneously.
Distribute in order further cold-producing medium to be carried out drainage, also be connected with Venturi tube 2 between the inlet of pipeline 3 and cylinder body 1, Venturi tube 2 can be distributed the cold-producing medium of coming in by pipeline 3 drainages and is mixed output to 1 li of cylinder body.Wherein the entrance side of cylinder body 1 can be arranged to the arc cavity, it is big that the arcuate structure of cylinder body 1 can form Venturi tube outlet space, can effectively reduce the flow velocity of cold-producing medium, avoids cold-producing medium cold-producing medium to occur and vertically clash into distributor 5, cause cold-producing medium to separate once more, lamination occurs.
In one embodiment, described distributor 5 specifically can be a liquid-distributing plate 10, and as Fig. 2 and Fig. 3, liquid-distributing plate 10 is provided with a plurality of capillaries 9, and this liquid-distributing plate 10 is connected with the exit seal of cylinder body 1.In the concrete application implementation, the outlet of liquid-distributing plate 10 and cylinder body can be tightly connected by gasket seal 4, adopts such being tightly connected can guarantee the pressure differential that forms in the cylinder body 1.
In order to stablize the distance between liquid-distributing plate 10 and the heat exchanger tube 8, on described liquid-distributing plate 10, also be provided with at least one landing nipple 6, be installed between capillary and the heat exchanger tube, be provided with intermediate throughholes in the middle of this landing nipple 6, capillary 9 is inserted in this intermediate throughholes, extend in the heat exchanger tube 8, as Fig. 4.For further secure heat exchanger tube 8, between heat exchanger tube 8, also be provided with tube sheet 7.
In one embodiment, each length capillaceous is identical with internal diameter, and the cold-producing medium that enters each heat exchanger tube with assurance is even, can further improve the heat exchange efficiency of whole heat exchanger, and control the degree of superheat of whole heat exchanger easily.
Above-described embodiment of the present invention does not constitute the qualification to protection domain of the present invention.Any modification of being done within the spirit and principles in the present invention, be equal to and replace and improvement etc., all should be included within the claim protection domain of the present invention.
