Device.
Further, it is in charge of in interface 2 two, the caliber of first branch outlet 22 is greater than the second branch outlet 23
Caliber.In this way, after refrigerant is in charge of the two of interface 2 with certain pressure inflow two and is in charge of entrance 21, due to the first branch outlet
22 caliber is greater than the caliber of the second branch outlet 23, in this way, flowing through the refrigerant of the first branch outlet 22 under identical pressure
Amount is greater than the coolant quantity for flowing through the second branch outlet 23, that is, the coolant quantity being flowed into upper pipeline, which will be more than, is flowed into down tube
Coolant quantity in road.If not considering the influence of refrigerant gravity, at this point, the coolant quantity in upper pipeline is compared with the coolant quantity in lower pipeline
More, the distribution of refrigerant in condenser is simultaneously unbalanced, but after considering the influence of refrigerant gravity in condenser, due to refrigerant gravity
Effect, it is believed that the refrigerant in upper pipeline is understood some and is flow in the lower pipeline of lower, when tune appropriate
After saving the parameters such as the caliber of refrigerant pressure, the caliber of the first branch outlet 22, the second branch outlet 23, refrigerant can be made to condense
Reach equally distributed state in device, i.e. upper pipeline is consistent with the coolant quantity in lower pipeline.It in this manner, can be into one
Step avoid refrigerant it is excessive be deposited in condenser bottom, cause during air-conditioning heating, the frosting of condenser bottom is not easy to melt
The case where occur.
Further, second branch outlet 23 includes that the first vertical section 231, back-flexing section 232 and second are vertical
Section 233, first vertical section 231 and the second vertical section 233 are connect with the both ends of back-flexing section 232 respectively, and refrigerant is upward
Flow through the first vertical section 231, using back-flexing section 232 carry out it is reversed after, by the second vertical section 233 to flowing down
It is dynamic, flow into lower pipeline inlet 103.Due to the acting in opposition of back-flexing section 232, make it possible to further divide inflow second
Coolant quantity in branch outlet 23 is limited, so that more refrigerants are flowed into from the first branch outlet 22 and are located at condensation
In the upper pipeline on device top.In practical applications, the comprehensive bending degree that back-flexing section 232 is set, first point can be passed through
Branch exports 22 calibers and the parameters such as 23 pipe diameter size of the second branch outlet and refrigerant feed liquor pressure, reaches equiblibrium mass distribution condenser
The purpose of middle refrigerant, so that condenser bottom is not easy frosting in air-conditioning heating work.
In the utility model, what " connection " word indicated is to have mutual access between pipeline, and refrigerant is existed
It is flowed between interconnected pipeline, and does not limit the concrete form of connecting line.Dotted line in Fig. 2 is illustratively to show
Connected relation between different U pipes out, does not limit the particular techniques index such as length, size, type of specific connecting line.
Specifically, the caliber of first branch outlet 22 are as follows: outer diameter 7mm, internal diameter 5.6mm；
