When can shunt portion produce liquid stream sound, and then cause product operation noise it is big, influence usage experience.In order to solve above-mentioned ask
Topic, it is specific as follows this application provides a kind of current divider：
As depicted in figs. 1 and 2, the current divider of the present embodiment includes current divider body 10, fluidic channel 20 and split channel
40.Wherein, fluidic channel 20 is arranged in current divider body 10, and the first end of fluidic channel 20 extends to current divider body 10
Outer surface simultaneously forms inlet 30.Split channel 40 is arranged in current divider body 10, and split channel 40 is multiple, and each shunting is logical
The first end in road 40 connects with the second end of fluidic channel 20, and the second end of each split channel 40 extends to current divider body 10
Outer surface and form liquid outlet 50.Preferably, the length of fluidic channel 20 is more than or equal to any place of fluidic channel 20
Two times of diameter.
Using the technical scheme of the present embodiment, the length of fluidic channel 20 is more than or equal to the diameter of fluidic channel 20
Twice.Said structure causes fluidic channel 20 to have longer distance.When refrigerant flows in fluidic channel 20, gas phase refrigerant and
Liquid phase refrigerant can be sufficiently mixed, and then produce stable vaporific flow pattern, so as to reduce noise caused by liquid stream sound.Cause
The technical scheme of this present embodiment solves the problems, such as that noise is larger in air conditioner running of the prior art.
As shown in Fig. 2 in the technical scheme of the present embodiment, fluidic channel 20 includes the first big footpath section 21 interconnected
With the first path section 22, the first big footpath section 21 is located at the first end of fluidic channel 20, the length of the first path section 22 and first small
The diameter of footpath section 22 meets following relation：
L≥2*D；
Wherein, L is the length of the first path section 22, and D is the diameter of the first path section 22.
Specifically, the fluidic channel 20 in the present embodiment is in shoulder hole structure, what the length of above-mentioned fluidic channel 20 referred to
It is the length of the first path section 22, the diameter of above-mentioned fluidic channel 20 refers to the diameter of the first path section 22.It is being not shown
Embodiment in, if fluidic channel 20 is the reducing pore structure that gradually changes of internal diameter, the length of fluidic channel 20, which is more than, penetrates
Two times of the maximum gauge of circulation road 20, so as to meet that " it is any that the length of fluidic channel 20 is more than or equal to fluidic channel 20
Two times of the diameter at place ".
Further, inventor has found, can regard flowing of the fluid in jet orifice as orifice flow, by invention
People's experiment shows, as L >=2*D, by increasing the length of fluidic channel 20, gas-liquid two-phase is sufficiently mixed, and is formed
Stable vaporific flow pattern, while fluid may be formed " throat's polycondensation " in fluidic channel 20, when fluid expansion, it can percussion
Wall, so as to destroy the condition of vortex thin layer vibration, then reduce noise caused by liquid stream sound.
Further, the first big footpath section 21 is located at the lower section of the first path section 22, and the internal diameter of the first big footpath section 21 is more than the
The internal diameter of one path section 22.Meanwhile first the lower end of big footpath section 21 form above-mentioned inlet 30.In the present embodiment, when
When fluidic channel 20 is the passage of reducing, the less part of internal diameter meets that the length of passage is more than two times of the internal diameter of passage
Relation, namely the first path section 22 in the present embodiment meets above-mentioned relation.Certainly, fluidic channel 20 is that an internal diameter is equal
During even passage, as long as making the overall length of fluidic channel 20 be more than the internal diameter of fluidic channel 20.Said structure can be protected
