Logical point of liquid room 2, and the liquid outlet 3 connected with described point of liquid room 2, if be provided with described point of liquid room 2 first hybrid chamber 4,
The first branch pipe 5 that dry root is arranged in an axially parallel mode along described point of liquid room 2 and second of the axially vertical setting along described point of liquid room 2
Branch pipe 6, the both sides of inlet 1 set to be formed between two pieces of dividing plates 7, two pieces of dividing plates 7 and set in one section of opening, the opening
Restricting orifice 8 is equipped with, first branch pipe 5 is provided with the second liquid outlet 9, second liquid outlet 9 close to open at one end and set
Electric control valve 10 and pressure sensor 11 are equipped with, second branch pipe 6 sets the second feed liquor close to the side of the first branch pipe 5
Mouthfuls 12, opposite side sets the 3rd liquid outlet 13, and the branch pipe gradually shrinks in one end close to opening to inner side, in round table-like,
The length of the dividing plate 7 is slightly longer than the branch pipe, and the one end of the dividing plate 7 away from inlet 1 gradually shrinks to be formed to inner side
A bit of opening, the open height is the 1/2 of the height of inlet 1.
Specifically, gas-liquid two-phase cold-producing medium flows into the first branch pipe 5 from inlet 1, and the length of first branch pipe 5 can root
It is configured according to use requirement, the length of runner determines gas-liquid two-phase fluid mixture homogeneity.First branch pipe 5 does not have
Conventionally it is made uniform cylindrical shape, but in round table-like, is arranged such, refrigerant goes out flowing to second from inlet 1
During liquid mouthful 9, because the radius of runner is gradually reduced, the flow velocity of refrigerant is gradually stepped up, and is conducive to the uniform mixed of gas-liquid
Close.Cavity is formed between each described first branch pipe 5, refrigerant is after second liquid outlet 9 outflow, into the cavity,
Gas-liquid turbulent flow is formed in the cavities, secondary mixing is realized, the gas-liquid mixed uniformity is improved again.The refrigerant is in the cavity
Enter the second branch pipe 6 from the second inlet 12 after interior turbulent flow, second branch pipe 6 sets rectangular-shaped, the cavity volume of growing up
Larger, inside hoards a large amount of refrigerating fluids, and a large amount of refrigerant moments flow into from the second inlet 12, cause in second branch pipe 6
Portion's pressure increase, is compressed to the refrigerating fluid of entrance, the gas-liquid mixed uniformity is improved again, realizes that third time is mixed, mixing
Flowed out after uniform from the 3rd liquid outlet 13, the mixture homogeneity of gas-liquid two-phase cold-producing medium now is ideal.
The present invention is provided with restricting orifice 8 between the first hybrid chamber 4 and the second hybrid chamber 14, from the 3rd liquid outlet
The refrigerant of 13 outflows, due to section sudden contraction, improves the kinetic energy of refrigerant by the restricting orifice 8, flow velocity increase,
Both sides form pressure differential when by restricting orifice 8, and the rear side of restricting orifice 8 is provided with the second hybrid chamber 14, high speed
Refrigerant generates vortex after second hybrid chamber 14 is entered, so that refrigerant air-liquid two-phase is sufficiently mixed, and realizes the
Four mixing.

The pressure value of gas-liquid near liquid mouthful 3.
Expansion valve come gas-liquid two-phase cold-producing medium, by inlet 1 enter each first branch pipe 5 because each first
The pressure drop of branch pipe 5 is much larger than the pressure drop of evaporator, and the caliber of each the first branch pipe 5 is identical with length, so having phase on each branch pipe
Same resistance, can flow into the refrigerant of equivalent, but in actual motion, the resistance of each branch pipe is different, cause each
The difference of branch pipe liquid supply rate, so the present invention sets pressure sensor 11 in each mouth of pipe, the pressure sensor 11 is used for
Detect each mouth of pipe pressure.
Specifically, the pressure value detected is real-time transmitted to remote terminal, remote terminal root by each pressure sensor 11
Judge whether the resistance in each branch pipe is identical according to the pressure value received, if judging the pressure that some pressure sensor 11 is sent
When force value has abnormal, then to the corresponding output control signal of electric control valve 10 of the pressure sensor 11, the electric control valve 10
The aperture of the second liquid outlet 9 is adjusted according to the control signal received.For example, there is a pressure value less than normal, remote terminal is to the pressure
The corresponding electric control valve 10 of force snesor 11 exports the first control signal, and the electric control valve 10 reduces opening for the second liquid outlet 9
Degree, increases the pressure in correspondence branch pipe by reducing the flow of the second liquid outlet 9, reaches the mesh for balancing each branch pipe internal drag
's；If there is a pressure value bigger than normal, remote terminal is believed to the corresponding control of the output of electric control valve 10 second of the pressure sensor 11
Number, the electric control valve 10 increases the aperture of the second liquid outlet 9.
