[0061] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

[0062] The present invention is described in detail below in conjunction with the accompanying drawings of the specification.

[0065] Figure 2 It is a schematic diagram of the volute structure provided by the present invention, from Figure 2 It can be seen that the induced draft circle 20 provided by the present invention is an elliptical structure. The wind speed of the induced draft circle 20 of the present invention is faster in the elliptical position, so that a larger air intake volume can be obtained, thereby forming a wind field with a faster wind speed and a more uniform wind field inside the volute, thereby obtaining a larger air volume at the volute outlet 12, and reducing the noise of the volute.

It is flexible to change and widely applicable, and at the same time reduces the noise in the volute.

[0076] The present invention will be described in detail below in conjunction with specific implementation modes.

[0077] In some specific embodiments of the present invention, Figures 1 to 9 As shown, the present scheme provides a volute, comprising: a shell 10, an air flow channel 30 is formed inside, and an air inlet 11 and an air outlet 12 are respectively formed at the two side ends of the air flow channel 30; an induced draft ring 20, arranged at the air inlet 11 of the air flow channel 30; wherein the induced draft ring 20 comprises: two induced draft sub-rings 21 arranged in a semicircular shape and two transition sections 22; the centers of the two induced draft sub-rings 21 are eccentrically arranged; and each transition section 22 is respectively connected to the same side of the two induced draft sub-rings 21.

[0078] It should be noted that the existing volute draft ring 20 is circular, which has certain advantages during processing. However, since the airflow channel 30 is respectively connected to the air inlet 11 and the air outlet 12, and the direction of the airflow channel 30 is not a perfect circle, the circular draft ring 20 has a problem that after the airflow enters the airflow channel 30, the flow velocity is affected by the inner wall of the airflow channel 30, and is unevenly distributed in the airflow channel 30, causing a large noise problem. At the same time, the airflow flow at the air outlet 12 is insufficient.

[0079] It can be understood that in order to solve the above-mentioned defects, the present invention sets the air induction ring 20 of the volute to an elliptical structure, which improves the aerodynamic performance of the airflow channel 30, optimizes the distribution of the wind field in the airflow channel 30, and reduces the noise when the airflow passes through the airflow channel 30. At the same time, the optimized airflow channel 30 also improves the airflow flow rate at the volute outlet 12.

[0080] Furthermore, the wind field of the induced draft ring 20 of the present invention has a faster wind speed in the elliptical position, so that a larger air intake volume can be obtained, thereby forming a faster and more uniform wind field inside the volute, thereby obtaining a larger air volume at the volute outlet 12.

[0081] In a possible embodiment, the induced draft ring 20 is configured to include two induced draft sub-rings 21 and two transition sections 22, and the two induced draft sub-rings 21 are respectively connected through the transition sections 22, so that the induced draft ring 20 forms an elliptical induced draft structure, thereby optimizing the distribution and flow velocity of the airflow inside the airflow channel 30, improving the overall performance of the airflow channel 30 and even the volute, and optimizing the electrical equipment installed with the volute.

[0082] In some possible implementations of the present invention, the direction of the line connecting the centers of the two induced draft subcircles 21 is inclined toward the air outlet 12 .

[0083] Specifically, this embodiment provides an implementation method of two induced draft sub-rings 21, by tilting the two induced draft sub-rings 21 toward the side of the air outlet 12, so that the airflow can obtain a better inlet angle when entering the airflow channel 30, thereby optimizing the distribution and flow rate of the airflow in the airflow channel 30, and reducing the problem of large noise caused by the airflow hitting the inner wall of the airflow channel 30.

[0084] In some possible embodiments of the present invention, it also includes: a first direction N, which is perpendicular to the air outlet direction of the air outlet 12 and the air inlet direction of the air inlet 11; wherein the connecting line direction forms an eccentric angle 23 with the first direction N, and the eccentric angle 23 is greater than 0° and less than or equal to 85°.

[0085] Specifically, this embodiment provides an implementation of the eccentric angle 23 of two induced draft sub-rings 21. By setting the eccentric angle 23, the specific quantification of the inclination of the induced draft ring 20 is achieved, and the induced draft ring 20, air flow channel 30, etc. can be optimized according to different needs.

[0086] It should be noted that factors such as fan type, volute thickness, motor power, etc. will cause the eccentric angle 23 to change.

[0087] In a possible embodiment, generally, the larger the outlet angle of the fan blade is and the smaller the inlet angle is, the smaller the value of the eccentric angle 23 is; the smaller the outlet angle is and the larger the inlet angle is, the larger the value of the eccentric angle 23 is. The size of the inlet angle determines the flow rate and distribution of the airflow after entering the airflow channel 30, thereby affecting the speed and flow rate of the airflow when it flows out from the air outlet 12.

[0088] In some possible implementations of the present invention, the ratio of the eccentric distance 24 of the two induced draft element rings 21 to the diameter of the induced draft element ring 21 is greater than 0 and less than or equal to 0.09.

[0089] Specifically, this embodiment provides an implementation method of the eccentric distance 24 of the two induced draft sub-rings 21. By setting the eccentric distance 24, the two induced draft sub-rings 21 are eccentric and separated, and in conjunction with the transition section 22, the induced draft ring 20 finally forms an elliptical induced draft structure.

[0090] It should be noted that the size of the eccentric distance 24 generally depends on the height of the volute itself, and is generally about 5% of the height of the volute, and will be appropriately adjusted according to actual conditions.

[0091] In some specific embodiments of the present invention, Figures 1 to 10 As shown, this solution provides a method for optimizing the volute, comprising:

[0092] Determine the spiral line 13 based on the fan characteristic value of the fan, and determine the position characteristic values ​​of the air inlet 11 and the air outlet 12 of the volute based on the spiral line 13, wherein the fan characteristic value at least includes the type parameter, size parameter and structure parameter of the fan, and the position characteristic value at least includes the position parameter and contour parameter of the air inlet 11 and the air outlet 12;

[0093] Determine the characteristic value of the air inlet 11, the air outlet 12 and the spiral line 13;

[0094] The optimization decision of the volute is determined based on the helix 13, the position characteristic value and the induced draft ring 20 characteristic value.

[0095] In some possible implementations of the present invention, the step of determining the characteristic value of the air inlet 11, the air outlet 12 and the spiral line 13 of the air inlet 11 includes:

[0096] Based on the air inlet 11, the air outlet 12 and the spiral line 13, the channel trajectory characteristics of the air flow channel 30 of the volute are determined;

[0097] Based on the air inlet 11 , the air outlet 12 and the channel trajectory characteristics, the eccentric angle 23 and the eccentric distance 24 of the induced draft coil 20 are determined, and the characteristic value of the induced draft coil 20 is determined according to the eccentric angle 23 and the eccentric distance 24 .

[0098] Specifically, this embodiment provides an implementation method for determining the characteristic value of the induced draft ring 20, and determines the channel trajectory characteristics of the air flow channel 30 inside the volute according to the air outlet 12, the air inlet 11 and the spiral line 13, that is, the approximate position of the air flow channel 30 in the volute, thereby providing a basis and reference for determining the eccentric angle 23 and the eccentric distance 24 of the induced draft ring 20, and then determining the relevant parameters of the final volute and the induced draft ring 20 according to the flow velocity, distribution and flow rate changes of the air flow at different eccentric angles 23 and eccentric distances 24.

[0099] In some possible implementations of the present invention, based on the air inlet 11, the air outlet 12 and the channel trajectory characteristics, the step of determining the eccentric angle 23 of the air induction ring 20 specifically includes:

[0100] Based on the air inlet 11, the air outlet 12 and the channel trajectory characteristics, determine the first direction N and the initial position of the air induction ring 20;

[0101] Based on the initial position and the first direction N, a reference diameter of the air induction ring 20 parallel to or overlapping the first direction N is determined;

[0102] When the performance threshold of the volute is met, the offset angle of the induced draft ring 20 is determined.

[0103] Specifically, this embodiment provides an implementation method for determining the eccentric angle 23 of the induced draft coil 20. The initial position and the first direction N of the induced draft coil 20 are determined according to the air inlet 11, the air outlet 12 and the channel trajectory characteristics, and the offset angle of the induced draft coil 20 is determined in combination with the reference diameter of the induced draft coil 20.

[0104] In some possible implementations of the present invention, the step of determining the eccentric distance 24 of the air inlet 11, the air outlet 12 and the channel trajectory characteristics specifically includes:

[0105] Based on the first direction N and the induced draft circle 20, two induced draft subcircles 21 are determined, and a dividing line between the two induced draft subcircles 21 is perpendicular to the first direction N;

[0106] When the performance threshold of the volute is met, the eccentric distance 24 of the two induced draft element rings 21 is determined based on the reference diameter and the offset angle.

[0107] Specifically, this embodiment provides an implementation method for determining the eccentric distance 24 of the induced draft circle 20. After the two induced draft circle 21 are determined, the two induced draft circle 21 are offset in combination with the first direction N. At the same time, the flow velocity, flow rate and distribution of the airflow in the airflow channel 30 are simulated to determine the performance threshold that can meet the volute. The eccentric distance 24 is determined based on the reference diameter and the offset angle, and the elliptical structure of the induced draft circle 20 is further determined.

[0108] In some possible implementations of the present invention, the performance threshold of the volute includes at least: the airflow velocity and airflow distribution of the airflow through the airflow channel 30 , and the airflow flow rate of the airflow through the air inlet 11 .

[0109] Specifically, this embodiment provides an implementation method for the performance threshold of the volute, and the performance threshold of the volute is a corresponding reference indicator provided according to the setting of relevant parameters, the involvement of national standards or performance requirements. Through the fine-tuning of the position, shape and ellipse of the induced draft ring 20, the performance threshold required by the volute is finally determined, and then the elliptical induced draft ring 20 of the optimized volute is determined.

[0110] It should be noted that the judgment on whether the performance threshold of the volute is met is based on a real-time simulation based on parameters such as the instant spiral line 13, air inlet 11, air outlet 12, air flow channel 30, eccentric angle 23 and eccentric distance 24, combined with actual product operating parameters. The simulation content includes the velocity, distribution and flow of the air flow in the air flow channel 30, at the air inlet 11, at the air outlet 12, etc., and the corresponding noise estimation.

[0111] In some specific embodiments of the present invention, Fig.11 As shown, the present solution provides a volute optimization device, comprising: a first determination module 40, a second determination module 50 and a decision generation module 60;

[0112] The first determination module 40 is used to determine the spiral line 13 based on the fan characteristic value of the fan, and determine the position characteristic values ​​of the air inlet 11 and the air outlet 12 of the volute based on the spiral line 13, wherein the fan characteristic value at least includes the type parameter, size parameter and structure parameter of the fan, and the position characteristic value at least includes the position parameter and contour parameter of the air inlet 11 and the air outlet 12;
