Problems solved by technology

[0003] In the related art, the flow divider used on the market has an accelerating chamber on the main channel to solve the problem of uneven refrigerant flow distribution, but this will reduce the inner diameter of the main channel, reduce the flow of refrigerant, and cause the flow rate of the evaporator to be relatively low. Small, reducing the heat transfer efficiency and causing the air conditioner to overheat

Embodiment 1

[0040] Example 1, please refer to figure 1 , figure 1 is a schematic cross-sectional view of the flow divider in the embodiment of the present application.

[0041] The flow divider 1 of the present application includes a main channel 2 and a branch channel 3 connected thereto. The main channel 2 includes a wide-diameter portion 21 and a narrow-diameter portion 23. The wide-diameter portion 21 is a relatively wide flow channel of the main channel, so The narrow-diameter portion 23 is a relatively narrow flow channel for the main flow channel, and a hollow ring groove 4 with a trapezoidal cross section is set in the narrow-diameter portion 23, see figure 1 , when the main flow channel 2 and the first branch branch 32 and the second branch branch 33 are on the same plane as the first viewing angle, in this viewing angle, the plane perpendicular to the radial direction of the main flow channel is taken as the section, the The radial direction is the direction of the radius or d...

Embodiment 2

[0043] Embodiment 2, in order to further increase the flow of refrigerant in the flow divider, the structural strength of the tank wall can be further strengthened, so that the tank wall of the flow divider can be made thinner, please refer to Figure 2-Figure 6 ,Specifically:

[0044] Based on the structure of the first embodiment above, at least two hollow ring grooves 4 are provided in the narrow diameter portion 23 .

[0045] see figure 2, the parallel short sides of the trapezoid that the cross section of the hollow ring groove 4 presents is the groove top 44, and the parallel long sides of the trapezoid that the cross section of the hollow ring groove 4 presents is the groove bottom 45, when at least two hollow ring grooves are set at the narrow diameter portion 23 4 o'clock, including the first hollow ring groove 41 and the second hollow ring groove 42, in the hollow ring groove, the groove top 44 close to the wide diameter part 21 is the first hollow ring groove 41, ...

Embodiment 3

[0052] Embodiment 3, when the refrigerant fluid flows into the flow divider, due to the fast flow speed, the refrigerant fluid hits the wall of the flow divider and generates a lot of noise. In order to solve the above problems, this application proposes a corresponding solution, please refer to Figure 7 ,Specifically:

[0053] see Figure 7 , on the basis of Embodiment 1, when at least two hollow ring grooves 4 are provided on the narrow diameter portion 23, the acute angles of the trapezoidal shapes presented by the cross sections of the first hollow ring groove 41 and the second hollow ring groove 42 are different. The acute angles are not the same, which means that when there are only two hollow ring grooves, the trapezoidal acute angles of the sections of the two hollow ring grooves are different. When there are three or more hollow ring grooves, at least one hollow ring groove The acute angle of the trapezoid presented by the section of the groove is different from the...

Abstract

The invention relates to a flow divider and an air conditioner comprising the same. The flow divider comprises a main flow channel and branch flow channels which communicate with each other, the main flow channel comprises a wide-diameter part and a narrow-diameter part which communicate with each other, the narrow-diameter part internally comprises a hollowed-out annular groove with a trapezoidal section, and the section is perpendicular to the radial direction of the main flow channel. The air conditioner comprises the flow divider. According to the scheme, the structural strength of the groove wall of the narrow-diameter part can be effectively improved, the groove wall of the hollowed-out annular groove in the scheme can be manufactured to be thinner under the same structural strength, and therefore the narrow-diameter part provided with the hollowed-out annular groove has the larger volume, the refrigerant circulation amount in the flow divider is increased, and the performance of the flow divider is improved; meanwhile, due to the fact that the refrigerant circulation amount in the flow divider is increased, the flow quantity of a refrigerant entering an evaporator is also increased, and the heat exchange efficiency of the air conditioner comprising the flow divider is improved.

Description

technical field [0001] The present application relates to the technical field of air conditioners, in particular to a flow divider and an air conditioner with the flow divider. Background technique [0002] At present, in order to improve the heat exchange efficiency of the air conditioner, a flow divider is often used to divide the throttling refrigerant into several processes and distribute it to the evaporator to complete evaporation. As an important auxiliary equipment of the evaporator, the performance of the flow divider directly affects the flow of refrigerant entering each process of the evaporator. [0003] In the related art, the flow divider used on the market has an accelerating chamber on the main channel to solve the problem of uneven refrigerant flow distribution, but this will reduce the inner diameter of the main channel, reduce the flow of refrigerant, and cause the flow rate of the evaporator to be relatively low. Small, reducing the heat exchange efficie...
