In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Fig. 1 shows the structure of the flow distribution of refrigerant device that the utility model embodiment provides.Described device comprises current divider 11, capillary 12 and transition conduit 13.
Wherein, current divider 11 is used to receive the cold-producing medium of gas-liquid two-phase, and capillary 12 is connected with described current divider 11; Transition conduit 13 is connected with described capillary 12.
In specific implementation process, according to the flow path designs of the heat exchanger that is connected with described flow distribution of refrigerant device (scheming not shown), the flow distribution of refrigerant device of the utility model embodiment comprises some capillaries 12 and transition conduit 13.
See also Fig. 2, Fig. 2 is the schematic appearance of the capillary 12 of the utility model embodiment.
Described capillary 12 is structure in the shape of a spiral, and is conspicuous, changes the length of capillary 12, can change its resistance, thereby can carry out suitable allotment to the flow of the cold-producing medium of each inflow heat exchanger stream.The vibration and the noise that have produced when wherein, the utility model embodiment has avoided cold-producing medium to flow through capillary 12 by capillary 12 being arranged to helical structure.
See also Fig. 3, Fig. 3 is the structure of the transition conduit 13 of the utility model embodiment.
Wherein, the internal diameter of described transition conduit 13 from described capillary 12 junctions, be increase progressively successively stepped.Described transition conduit 13 comprises first order decompression tube 131, second level decompression tube 132, third level decompression tube 133, can certainly comprise more multistage decompression tube, is that example describes with three grades of decompression tubes only herein, and other situation is not just enumerated one by one.
First order decompression tube 131 connects capillary 12, and in specific implementation process, the length of first order decompression tube 131 is generally 20-25mm, and its caliber is than the big 0.5-1.5mm of caliber of capillary 12 direct-connected with it;
The length of second level decompression tube 132 is 1.1-1.2 times of first order decompression tube 131, and its caliber is than the big 0.5-2.5mm of caliber of first order decompression tube 131 direct-connected with it;
The length of third level decompression tube 133 is 1.1-1.2 times of second level decompression tube 132, and its caliber is than the big 0.5-2.5mm of caliber of its direct-connected second level decompression tube 132;
