The structure arrangement ensures that when fluid flows into the second transition cavity section, the flow section of the fluid is gradually increased due to the fact that the second transition cavity section is the variable diameter cavity section, and acoustic impedance of noise is changed; and under the action of the cavity wall of the second transition cavity section, the sound wave propagating along the cavity of the second transition cavity section is reflected back towards the inlet port 12, so that the sound wave reflection and interference are caused, and the sound energy radiated to the outside of the shell 10 is reduced.

Specifically, the fluid flow cross section entering the cavity section 116 is smaller than the fluid flow cross section of the mixing cavity section 111, and a third transition cavity section 115 is arranged between the entering cavity section 116 and the mixing cavity section 111, so that the entering cavity section 116 is communicated with the mixing cavity section 111 through the third transition cavity section 115; i.e. in the direction of flow of the fluid in the flow-through chamber 11, the fluid flow cross-section of the third transition chamber section 115 gradually increases. Due to the structural arrangement, when the fluid flows into the third transition cavity section 115, the flow cross section of the fluid is gradually increased because the third transition cavity section 115 is a variable diameter cavity section, so that the acoustic impedance of the noise is changed; and under the effect of the cavity wall of the third transition cavity section 115, the sound wave propagating along the cavity of the third transition cavity section 115 is reflected back toward the inlet port 12, so as to cause sound wave reflection and interference, thereby reducing the sound energy radiated to the outside of the housing 10, so as to perform a noise reduction treatment on the fluid before the fluid enters the mixing cavity section 111, and further improving the noise reduction effect of the flow divider 100.
It should be noted that the outer circumference of the cross section of the cavity entering the cavity section 116 perpendicular to the flow direction of the fluid in the circulation cavity 11 is smaller than the outer circumference of the cross section of the cavity entering the cavity section 116 perpendicular to the flow direction of the fluid in the circulation cavity 11, the area of the cross section of the cavity entering the cavity section 116 perpendicular to the flow direction of the fluid in the circulation cavity 11 is smaller than the area of the cross section of the cavity entering the cavity section 111 perpendicular to the flow direction of the fluid in the circulation cavity 11, and the equivalent diameter of the cross section of the cavity entering the cavity section 116 perpendicular to the flow direction of the fluid in the circulation cavity 11 is smaller than the equivalent diameter of the cross section of the cavity entering the cavity section 111 perpendicular to the flow direction of the fluid in the circulation cavity 11.
For example, when the inlet chamber section 116 and the mixing chamber section 111 are both cylindrical chamber sections, the diameter of the cross section of the chamber body of the inlet chamber section 116 perpendicular to the flow direction of the fluid in the flow-through chamber 11 is smaller than the diameter of the cross section of the chamber body of the mixing chamber section 111 perpendicular to the flow direction of the fluid in the flow-through chamber 11.
It should be noted that the third transition cavity segment 115 is a tapered cavity; in the flow direction of the fluid in the circulation chamber 11, the outer perimeter of the cross section of the cavity of the third transition chamber section 115 perpendicular to the flow direction of the fluid in the circulation chamber 11 gradually increases, the area of the cross section of the cavity of the third transition chamber section 115 perpendicular to the flow direction of the fluid in the circulation chamber 11 gradually increases, and the equivalent diameter of the cross section of the cavity of the third transition chamber section 115 perpendicular to the flow direction of the fluid in the circulation chamber 11 gradually increases.
For example, when the third transition chamber section 115 is a conical chamber, the diameter of the cross section of the chamber body of the third transition chamber section 115 perpendicular to the flow direction of the fluid in the flow chamber 11 gradually increases in the flow direction of the fluid in the flow chamber 11.
In this embodiment, the entry cavity section 116 has a length L 1 The wavelength of the sound waves entering the cavity section 116 to be damped is λ 1 (ii) a Wherein L is 1 ＝(2n-1)×λ 1 And n is an integer greater than or equal to 1, namely n ═ 1,2,3 ….
In this embodiment, the size of the entry cavity segment 116 may also be set as follows: the equivalent diameter of the fluid flow cross-section entering the cavity section 116 is D 1 The equivalent diameter of the flow cross-section of the mixing chamber section 111 is D 2 (ii) a Wherein, 0.5D 1 ≤D 2 ≤2D 1 。
In the present embodiment, the swirling portion 20 includes a swirling body 21, the swirling body 21 has a cylindrical structure, and an extending direction of a central axis of the swirling body 21 is parallel to or the same as a flowing direction of the fluid in the circulation chamber 11.

In particular, as shown in fig. 6, the direction from the first end face to the second end face of the self-current body 21 is the same as the flow direction of the fluid in the circulation chamber 11.
It should be noted that, according to the two structural arrangement forms of the swirling portion 20, as shown in fig. 3, before the fluid passes through the swirling portion 20, the fluid has no definite tangential flow velocity, and after the fluid passes through the swirling portion 20, the fluid can obtain a larger tangential flow velocity, that is, the flow direction of the fluid can be deflected to a certain extent, so that the fluid has a tendency of flowing spirally, and after the fluid flowing spirally flows into the flow splitting cavity section 112, the fluid can be prevented from forming an obvious gas-liquid boundary under the action of gravity, thereby ensuring the mixing uniformity of the fluid; therefore, when the fluid is a gas-liquid two-phase mixture, the flow divider 100 can ensure the mixing uniformity of the gas-liquid two-phase mixture, and further ensure the distribution uniformity of the gas-liquid two-phase mixture, that is, the flow divider 100 has high flow dividing performance.
