Specific embodiment
The embodiment 1 of refrigerant distributor of the present invention is illustrated below with reference to Fig. 1 and Fig. 2, which is set to a collection
In flow tube 2, header 2 is that distributor 1 conveys refrigerant by inlet tube 5, and the flat tube 30 of micro-channel heat exchanger 3 connects header
2, which is equipped with several branched pipes 10, and the refrigerant that inlet tube 5 enters enters branched pipe 10 from branched pipe input end
Interior, branched pipe outlet end is connected to flat tube 30 so that refrigerant is inputted flat tube.2 left end of header is equipped with a mixing chamber 4, mixing
Room left end is connected to inlet tube outlet end, and branched pipe input end is connected to mixing chamber 4.Several branched pipe input ends directly with it is mixed
Room connection is closed, the branched pipe is inShape.Inlet tube 5 exists in the outlet of mixing chamber 4 and several branched pipes
The import of mixing chamber then flows into branched pipe by reinforcing mixing uniformity after hitting using the structure of face be staggered, non-
Import.
Refrigerant distributor 1 is welded by being composed after two panels aluminium sheet punch forming with product.Refrigerant is from import
Pipe 5 enters refrigerant distributor 1 after being sufficiently mixed into mixing chamber 4, by the stream for designing each branched pipe 10 of refrigerant distributor
The bending radius of logical area and bend, keeps the flow resistance of each branched pipe 10 identical.Therefore, regardless of the refrigerant stream of inlet tube 5
Whether amount changes, and since the flow resistance of each branched pipe 10 is identical, it is also uniform for flowing through the refrigerant flow of each branched pipe 10.
The embodiment 2 that refrigerant distributor of the present invention is illustrated below with reference to Fig. 3 and Fig. 4, the difference with embodiment 1
It is, distributor 1 is drawn one from mixing chamber 4 and connected to the supervisor 11 of extension in the middle part of distributor, supervisor's input end and mixing chamber 4
Logical, supervisor outlet end is connected to several 10 input ends of branched pipe.11 outlet ends of the supervisor are located at 1 middle part of distributor, described
Branched pipe 10 is inShape is to scattering at left and right sides of distributor 1.Inlet tube 5 is being mixed in the outlet of mixing chamber 4 with supervisor 11
The import of room using face be staggered, non-structure, by reinforcing mixing uniformity after hitting, then flow into supervisor 11 into
Mouthful.
Refrigerant enters the supervisor 11 of refrigerant distributor 1 after being sufficiently mixed from inlet tube 5 into mixing chamber 4, then by leading
Refrigerant is distributed to each branched pipe 10 by pipe 11, similarly, by designing the circulation area of each branched pipe 10 and the bending of bend
Radius keeps the flow resistance of each branched pipe 10 identical, and the refrigerant flow for flowing through each branched pipe 10 is uniform.
The embodiment 3 that refrigerant distributor of the present invention is illustrated below with reference to Fig. 5, is with the difference of embodiment 2,
The input end of the supervisor of distributor 1 11 is directly connected to 5 outlet end of inlet tube.Mixing chamber is no longer set.
Refrigerant is directly entered the supervisor 11 of refrigerant distributor 1 from inlet tube 5, then is distributed to refrigerant by supervisor 11
Each branched pipe 10 similarly by designing the circulation area of each branched pipe 10 and the bending radius of bend, makes each branched pipe 10
Flow resistance is identical, and the refrigerant flow for flowing through each branched pipe 10 is uniform.
The embodiment 4 that refrigerant distributor of the present invention is illustrated below with reference to Fig. 6 and Fig. 7, the difference with embodiment 1
Be, a mixing chamber 4 is equipped in the middle part of distributor 1, and 5 outlet end of inlet tube is connected to the mixing chamber 4, mixing chamber 4 with it is several
10 input end of root branched pipe is directly connected to, and branched pipe 10 is inShape is to scattering at left and right sides of distributor 1.
Refrigerant is directly entered the mixing chamber 4 of refrigerant distributor 1 from inlet tube 5, mixes two phase of refrigerant air-liquid
Uniformly, then by mixing chamber 4 by refrigerant it evenly distributes to each branched pipe 10, similarly, by the circulation for designing each branched pipe 10
The bending radius of area and bend keeps the flow resistance of each branched pipe 10 identical, flows through the refrigerant flow of each branched pipe 10
Uniformly.
The embodiment 5 that refrigerant distributor of the present invention is illustrated below with reference to Fig. 8 is each side set in distributor 1
There is a mixing chamber 4,2 both ends of header are respectively provided with an inlet tube 5 and enter distributor 1 and be connected to the mixing chamber 4, the mixing chamber 4
It is connect with 10 input end of branched pipe, the branched pipe 10 drawn from mixing chamber 4 is inShape is dissipated at left and right sides of the mixing chamber 4
It opens.
The embodiment 6 of refrigerant distributor of the present invention is illustrated below with reference to Fig. 9,2 end of header is respectively provided with a mixing
It is respectively provided with a 11 pipe input ends of supervisor at left and right sides of 4 distributor of room and mixing chamber 4 is logical, supervisor outlet end and branched pipe input end
Connection is scattered from the 10 " shape of branched pipe that supervisor outlet end is drawn to the supervisor outlet end left and right sides.
When 30 quantity of flat tube more (i.e. 2 length of header is longer), in order to preferably distribute refrigerant, it is sometimes desirable to from
Both ends flow into refrigerant simultaneously, and both ends refrigerant is each assigned to each branched pipe by two supervisors of distributor 1.Here it is adopt
The structure of Example 5 and embodiment 6.
