As shown in Fig. 1～10, refrigerant flow dividing structure provided by the present invention comprises cylinder 1, is provided with shunting chamber 2, refrigerant inlet 4 and runner on cylinder 1.Wherein: described runner is the flute profile runner 5 arranging along the outer surface of cylinder 1, refrigerant inlet 4 and each shunting chamber 2 are communicated with via flute profile runner 5 fluids.Being not intended is herein confined to refrigerant inlet 4 and is directly communicated with each shunting chamber 2 fluid by flute profile runner 5, and refrigerant inlet 4 can also be shunted chamber 2 via flute profile runner 5 and the parts except flute profile runner 5 and each and carry out fluid and be communicated with.The present invention can be by one or more parameters in track curvature, path length, cross-sectional area and the shape of cross section of control flute profile runner, thereby can control the amount that enters the cold-producing medium in shunting chamber, for the sendout of accurately controlling cold-producing medium provides condition.
In above-described embodiment, several shuntings chamber 2 is all opened in cylinder 1 surface and distributes along the axially spaced-apart of cylinder 1, such as: respectively shunt chamber 2 and all can extend to cylinder 1 inside from the outer surface of cylinder 1, form comb teeth-shaped.Each shunting chamber 2 is for placing flat tube 3, the number of the flat tube 3 that it holds can be one, can be also multiple, that is to say, can several flat tubes 3 by same shunting chamber 2 the supply system cryogens, can on the comparatively limited cylinder 1 of volume, realize more flow manifold like this.Certainly, the thickness sum of each flat tube 3 and the height in this shunting chamber 2 in each shunting chamber 2 is suitable.
Refrigerant inlet 4 is opened on cylinder 1 and shunts the part outside chamber 2, between refrigerant inlet 4 and each shunting chamber 2, is connected by flute profile runner 5, and each flute profile runner 5 is offered along the surface of cylinder 1.As can be seen from the figure: flute profile runner 5 around refrigerant inlet 4 radially.Flute profile runner 5 has import 51 and outlet 52, and import 51 is connected with refrigerant inlet 4, and outlet 52 connects shunting chamber 2.Therefore, cold-producing medium enters the import 51 of flute profile runner 5 from refrigerant inlet 4, arrives outlet 52, then entered in coupled logical shunting chamber 2 by outlet 52 via flute profile runner 5, is finally entered in flat tube 3 by shunting chamber 2.
Certainly, refrigerant inlet 4 can directly be communicated with each shunting chamber 2 fluid by flute profile runner 5.Also flute profile runner 5 can be set to bifurcation structure, make flute profile runner 5 have import and at least two outlets, this import is communicated with refrigerant inlet 4 fluids, and each exports corresponding fluid and is communicated with a shunting chamber 2.In the present embodiment, the flute profile runner 5 of bifurcation structure can spread shunting to cold-producing medium step by step, this simple in structure, has solved cold-producing medium and has distributed difficult problem, for the sendout of accurately controlling cold-producing medium provides condition.
For relative altitude lower than for the shunting chamber 2 of refrigerant inlet 4, the cold-producing medium of carrying from refrigerant inlet 4 is because Action of Gravity Field must have certain gravitional force, this gravitional force can change into the kinetic energy of cold-producing medium, so relative altitude is more easily assigned to cold-producing medium than relative altitude higher than the shunting chamber 2 of refrigerant inlet 4 lower than the shunting chamber 2 of refrigerant inlet 4, therefore, the intermediate altitude that refrigerant inlet 4 is arranged on cylinder 1 by the present invention is comparatively suitable, to ensure that distributed uniform is as principle as far as possible.
As can be seen from the above analysis: by controlling flute profile runner 5, can distribute equably the amount that enters the cold-producing medium in shunting chamber 2, and the structure of refrigerant flow dividing structure provided by the present invention is more simple with respect to traditional finned tube exchanger in prior art, and can be by flat tube 3 horizontal positioned while installing and using, therefore cold-producing medium flowing in flat tube 3 can not be subject to the impact of gravity, thereby the height of total flow dividing structure can not be affected, and then the scope of application is wider.
In above-described embodiment, at least one parameter in track curvature, path length, cross-sectional area and the shape of cross section of flute profile runner 5 is adjustable.The pressure of the refrigerant fluid of refrigerant inlet 4 is identical, by regulating one or more in track curvature, path length, cross-sectional area and the shape of cross section of flute profile runner 5, cold-producing medium can be accurately controlled from refrigerant inlet 4 to the pressure drop shunting chamber 2, thereby the refrigerant flow that enters shunting chamber 2 can be controlled.Refrigerant inlet 4 is less to the pressure drop between shunting chamber 2, less along resistance and the pressure loss of flute profile runner 5, and flow velocity is also just faster, and unit interval flow is also just larger.Below by parameters, the impact of the refrigerant flow that enters shunting chamber 2 is described.
1,, about track curvature, it refers to route that flute profile runner 5 will be walked or the radius of track, such as being straight path, and also can curvilinear path.Straight path wherein and curvilinear path are compared known: under the identical situation of path length, cross-sectional area and shape of cross section, the radius of curvature of straight path is less, cold-producing medium is after the flute profile runner 5 of straight path, the pressure loss is less, pressure drop is also just less, thereby it is relatively larger to distribute to the flow in shunting chamber 2.
2,, about path length, it refers to the distance that flute profile runner 5 will be walked.Under the identical situation of track curvature, cross-sectional area and shape of cross section, the shorter pressure loss of path length is less, and pressure drop is also just less, thereby it is relatively larger to distribute to the flow in shunting chamber 2.
