Wherein, along the extending direction of the first transition section 11 to the second transition section 12, the flow cross-sectional area of the first transition section 11 gradually increases, and the flow cross-sectional area of the second transition section 12 gradually decreases.
Specifically, the inlet of the flow divider in this embodiment is introduced with refrigerant. By adopting the structure, the fluid at the inlet of the flow dividing structure 10 is firstly slowed down through the first transition section 11 and then is rapidly accelerated in the second transition section 12, so that the fluid forms vortex in high-speed movement, the gas phase and the liquid phase of the refrigerant are fully mixed, the mixed gas phase and the mixed liquid phase enter the flow dividing section 13, the speed is reduced along with the increase of the loss of the refrigerant flowing in the flow dividing section 13 Cheng Zuli, and the mixed gas phase and the mixed liquid phase flow enter the outlet of the evaporator, and then flow into coils of each path of the evaporator for heat exchange. Since the flow cross-sectional area of the first transition section 11 is gradually increased, no vortex is generated; the vortex is generated in the second transition section 12, and the flow cross-sectional area of the second transition section 12 is gradually reduced, so that the vortex corresponding to the vortex is smaller in size, the generation of large-size vortex is avoided, the noise generated by the large-size vortex can be avoided, the noise source is weakened, the scouring sound of the refrigerant is lower, and the scouring sound can be effectively reduced.

Specifically, the second transition section 12 in the present embodiment is a first tapered section having a taper angle α, which is 40 ° or more and α or less than 50 °. With such a structural arrangement, it is possible to facilitate rapid acceleration of the refrigerant in the second transition section 12, and to facilitate flow of the refrigerant at a higher speed.
Specifically, the first transition section 11 has a length L2, and the second transition section 12 has a length L 4 ，11≤L 2 /L 4 And is less than or equal to 15. With this arrangement, it is possible to facilitate ensuring that the refrigerant passes through the first transition section 11 of a sufficient length and undergoes a certain deceleration in the first transition section 11 and swiftly advances in the second transition section 12The speed is increased to facilitate a smaller size vortex being created in the second transition section 12 to better reduce the flushing sound of the refrigerant.

In this embodiment, the flow dividing structure 10 further has a throat section 14, and the throat section 14 is disposed between the second transition section 12 and the flow dividing section 13, so that the refrigerant enters the throat section 14 through the second transition section 12, the liquid film of the refrigerant in the throat section 14 becomes thinner, and the flow pattern in the corresponding gas phase is closer to the mist flow shape, thereby improving the flow dividing performance. And the experiment proves that the refrigerant flushing sound can be effectively weakened and the duration is very short by arranging the throat section 14, so that the use comfort of a user is greatly improved.

By adopting the structure, the flow velocity of the refrigerant at the inlet section 15 can be conveniently and effectively reduced through the first transition section 11, the condition that the refrigerant generates vortex with larger size at the first transition section 11 due to overhigh flow velocity is avoided, and the condition that the flushing sound of the refrigerant is overhigh is further avoided.

By adopting the arrangement, the refrigerant can be efficiently split, and the flushing sound of the refrigerant of the air conditioner can be effectively solved.

Assuming that the refrigerant enters the first transition section 11 after entering the flow divider at a speed of 5m/s, the first transition section 11 should be designed to be 14% larger than the sectional area of the inlet section 15, the first transition section 11 is in a gradually expanding shape, and the length dimension of the first transition section 11 should be designed to be 4.5 times larger than the length dimension of the inlet section 15, at this time, the kinetic energy of the refrigerant in the flow channel is reduced, and the speed is reduced to 4.7m/s. Then, the refrigerant enters the second transition section 12, the refrigerant forms a tapered taper shape before entering the throat section 14, the corresponding taper angle is 45 degrees, the speed gradient in the flow channel is enhanced, the high-speed area and the low-speed area start to differentiate, and the speed is increased to 8.8m/s.
