So that the diameter of the first liquid feeding end 11 increases, if the diameter of the first liquid feeding end 11 is excessive, refrigerant will lead at each
Distribution between first diversion pipe 110 is uneven, and use each second diversion section 112 at least with two third diversion sections 113
The scheme of connection can make the quantity of the first diversion section 111 reduce, so that the diameter of the first liquid feeding end 11 is reduced, even if flat
The quantity of pipe increases, and the diameter of the first liquid feeding end 11, which not will increase, even to be reduced, and enables refrigerant in every first water conservancy diversion
It is evenly distributed in pipe 110.
As shown in Fig. 2, in one embodiment, every first diversion pipe 110 includes two third diversion sections 113, two
The setting of 113 relative spacing of third diversion section, and two third diversion sections 113 are connected to the second diversion section of same root 112.So that
Piece second diversion section 112 can carry out the supply of refrigerant to two third diversion sections 113 simultaneously.
In another embodiment, every first diversion pipe 110 includes three third diversion sections 113, three third water conservancy diversion
Section 113 relative spacings setting, and three third diversion sections 113 are connected to the second diversion section of same root 112.So that one second
Diversion section 112 can carry out the supply of refrigerant to three third diversion sections 113 simultaneously.
As shown in Figures 3 and 4, based on any of the above embodiments, refrigerant distributing device further includes at least two
Second diversion pipe 120, the second diversion pipe 120 are oppositely arranged with the first diversion pipe 110, and every second diversion pipe 120 is along refrigerant
The direction of the supply includes the 4th diversion section 121, the 5th diversion section 122 and the 6th water conservancy diversion being sequentially communicated, being mutually arranged in angle
Section 123, the 4th diversion section 121 is oppositely arranged with the first diversion section 111, the 4th water conservancy diversion of two adjacent second diversion pipes 120
Section 121 is bonded to each other setting, and the liquid feeding end of the 4th all diversion sections 121 cooperatively forms the second liquid feeding end 14, and the second feed liquor
End 14 cooperatively forms the liquid inlet joint 10 for being connected with feed liquid pipeline, two adjacent second water conservancy diversion with the first liquid feeding end 11
5th diversion section 122 of pipe 120 is bonded to each other setting, and all 5th diversion sections 122 cooperatively form and connect with the second liquid feeding end 14
The second logical circulation passage (not shown), every 6th diversion section 123 are arranged with 113 relative spacing of third diversion section, and all
The outlet end of 6th diversion section 123 cooperatively forms the second outlet end (not shown), and the second outlet end is connected to the second circulation passage,
And second outlet end the liquid outlet connector for matching with flat tube is cooperatively formed with the first outlet end 13.In this way, making refrigerant
Distributor can carry out the supply of refrigerant to the flat tube of the setting of upper and lower both direction or the setting of left and right both direction simultaneously,
Guarantee that refrigerant can be distributed uniformly in every flat tube；Further, can freeze to greater number of flat tube
Agent is evenly supplied, while overall structure can also be made to keep compact.
As shown in figure 3, further, the 4th diversion section 121 is arranged perpendicular to or approximately perpendicular to the 5th diversion section 122,
6th diversion section 123 is vertical or is arranged approximately perpendicular to the 5th diversion section 122.Since the 4th diversion section 121 is vertical or approximate vertical
Directly in the 5th diversion section 122, preferably the 4th diversion section 121 perpendicular to the 5th diversion section 122, the 6th diversion section 123 it is vertical or
Approximately perpendicular to the 5th diversion section 122, preferably the 6th diversion section 123 is perpendicular to the 5th diversion section 122, and the 4th diversion section
121 and the 6th diversion section 123 be respectively arranged at the two sides of the 5th diversion section 122, so as to by more second diversion pipes 120 into
Row is adjacent to split, so that the structure of refrigerant distributing device is more compact, meets the requirement of micro-channel heat exchanger, and add
Work simple process saves production cost；Further, more second diversion pipes 120, which carry out being adjacent to split, forms modular system
Refrigerant distribution device need to only carry out the splicing or dismounting of module when the quantity of flat tube changes according to the actual situation,
It is simple and convenient.And then when the first diversion pipe 110 and the second diversion pipe 120 are all made of this kind of structure, it can greatly improve entire
