[0031] Reference Figures 1 to 4 The present invention provides an integrated flow divider, comprising:

[0032] An input section 10, wherein the input section 10 is provided with an input channel 11 and a buffer chamber 12; and

[0033] The flow dividing section 20 is provided with a plurality of flow dividing channels 21. The input channel 11 and the plurality of flow dividing channels 21 are connected through the buffer chamber 12. The input section 10 and the flow dividing section 20 are integrally provided. The cross-sectional area of ​​the input channel 11 is S 1 The sum of the maximum cross-sectional areas of the plurality of diversion channels 21 is S 2 , S 1 >S 2 .

[0034] The integrated diverter in the technical solution of the present invention includes an input section 10 and a diverter section 20. The input section 10 is provided with an input channel 11 and a buffer chamber 12. The diverter section 20 is provided with multiple diverter channels 21. The input channel 11 and the multiple diverter channels 21 are connected through the buffer chamber 12. The input section 10 and the diverter section 20 are integrally arranged. Compared with the diverter formed by welding in the prior art, the integrally arranged diverter reduces the smoke and harmful substances generated during the welding process, reduces environmental pollution and physical damage to employees; at the same time, it also reduces the possibility of desoldering during the later welding process of the refrigeration equipment main unit and the pipeline, reduces the possibility of refrigerant leakage, and improves the reliability of the refrigeration equipment system; further, the integrally arranged diverter also avoids welding impurities from entering the diverter channel 21, reduces the possibility of clogging the diverter channel 21, and further improves the reliability of the refrigeration equipment system.

[0035] Furthermore, the cross-sectional area of ​​the input channel 11 is S 1 The sum of the maximum cross-sectional areas of the plurality of diversion channels 21 is S 2 , S 1 >S 2 . In the process of the fluid passing through the diverter, due to the large cross-sectional area of ​​the input channel 11, the flow rate of the fluid therein is relatively low, so the pressure loss generated by the fluid during the flow process will also be reduced accordingly, which helps to maintain the pressure stability of the fluid during the diversion process, thereby improving the operating efficiency of the entire refrigeration equipment system. At the same time, the larger cross-sectional area of ​​the input channel 11 allows the fluid to flow more smoothly when entering the diverter, reducing the retention and eddy current phenomenon of the fluid in the channel, thereby reducing the noise and wear generated by the diverter, and thus increasing the service life of the diverter.

[0036] Furthermore, the diameter of the input channel 11 is R 1 , the diameter of the buffer cavity 12 is R 2 , R 1 <R 2, that is, the cross-sectional area of ​​the buffer chamber 12 is larger than the cross-sectional area of ​​the input channel 11, so that when the gas or liquid enters the buffer chamber 12 from the input channel 11, the flow rate of the gas or liquid will be reduced, thereby reducing the impact on the internal structure of the diverter section 20, reducing the wear and noise of the diverter, and thus improving the stability and service life of the diverter. At the same time, the buffer chamber 12 is a transition area for the fluid from the input channel 11 to the multiple diverter channels 21, and its larger diameter helps the fluid to form a relatively stable flow state in the cavity. In this way, when the fluid enters each diverter channel 21 from the buffer chamber 12, it can be more evenly distributed to each channel, ensuring that the flow rate obtained by each channel is relatively consistent, thereby improving the diversion accuracy and efficiency. Furthermore, the fluid will generate a certain pressure loss when passing through the pipeline. In the diverter, since the diameter of the input channel 11 is smaller than the diameter of the buffer chamber 12, the fluid will undergo a diameter expansion process when entering the buffer chamber 12. During this process, the velocity of the fluid is reduced, and the kinetic energy is converted into pressure energy, thereby reducing the pressure loss in the subsequent flow process to a certain extent. Finally, the design of the buffer chamber 12 allows the fluid to be fully mixed and stabilized before entering the diversion channel 21, avoiding the problem of uneven diversion caused by uneven fluid velocity or unstable flow state. This design helps to improve the diversion efficiency of the diverter and ensure that each diversion channel 21 can receive fluid simultaneously and stably.

[0037] In one embodiment, the diverter channel 21 includes a first diverter section 211, the first diverter section 211 is connected to the buffer chamber 12, and the maximum spacing between the inner walls of the first diverter sections 211 of the diverter channels 21 is L, R 2 ≥L. If R 2 <L, the wall of the buffer cavity 12 will block part of the first diversion section 211, thereby reducing the amount of the buffer cavity 12 flowing into the diversion channel 21, thereby reducing the diversion efficiency of the diverter. 2 ≥L, so that the fluid in the buffer cavity 12 can flow out smoothly through the diverter channel 21, thereby improving the stability and reliability of the diverter, and further improving the diverter efficiency.

[0038] Specifically, the shunt channel 21 is stepped, and the diameter of the shunt channel 21 is increased in the direction away from the input channel 11. It can be understood that the flow velocity of the fluid in the pipeline is inversely proportional to its cross-sectional area. Therefore, when the diameter of the shunt channel 21 increases, the flow velocity of the fluid in the channel will be reduced accordingly, which helps to reduce the friction resistance between the fluid and the inner wall of the pipeline, thereby reducing energy loss, while also reducing wear and damage inside the pipeline, thereby increasing the service life of the diverter. At the same time, slowing down the flow rate also helps to reduce the generation of eddies and turbulence, thereby further reducing the resistance and pressure loss of the fluid. Further, high-speed fluids tend to generate greater noise and vibration, so by increasing the diameter of the shunt channel 21 to reduce the flow velocity, noise and vibration can be effectively reduced, thereby improving the stability of the refrigeration equipment system during operation.

[0039] In one embodiment, the wall thickness of the input section 10 is t 1 , t 1 ≥0.5mm; and / or the thickness of the wall of the buffer cavity 12 is t 2 , t 2 ≥0.5mm. Thus, the wall thickness of the input section 10 is increased, so that the input section 10 can still work stably under high pressure environment, thereby enhancing the pressure resistance of the diverter and thus increasing the service life of the diverter. If t 1 <0.5mm or t 2 If the thickness of the input section 10 is less than 0.5 mm, the input section 10 will be too thin, so that the high-pressure fluid entering the input section 10 may easily cause the diverter to be deformed and damaged, thereby reducing the service life of the diverter.

[0040] In one embodiment, the input section 10 includes an input main section 101, a connecting section 102 and a buffer section 103 which are arranged in sequence. The input main section 101, the connecting section 102 and the buffer section 103 are arranged in one piece. The buffer section 103 is arranged in one piece with the diversion section 20. The input channel 11 is located in the input main section 101, the buffer cavity 12 is located in the buffer section 103, and a first fillet 104 is formed between the input main section 101 and the connecting section 102. The radius of the first fillet 104 is r 1 , r 1 ≥0.5mm; and / or a second fillet 105 is formed between the connecting section 102 and the buffer section 103, and the radius of the second fillet 105 is r 2 , r 2≥0.5mm. The first fillet 104 is used as the transition part between the input main section 101 and the connecting section 102, and the second fillet 105 is used as the transition part between the connecting section 102 and the buffer section 103. The reasonable limitation of the diameter can enhance the structural strength of this area. The fillet design can reduce the stress concentration of the input section 10, reduce the risk of fracture due to material fatigue or external impact, and thus improve the stability and service life of the diverter. Furthermore, by 1 ≥0.5mm and / or r 2 ≥0.5mm, thereby improving the transition smoothness between the input main section 101, the connecting section 102 and the buffer chamber 12, which can indirectly promote the smooth flow of the fluid. A smaller fillet diameter may increase the resistance of the fluid flow, and a reasonable fillet design can reduce this resistance, ensuring that the fluid can smoothly enter the buffer chamber 12 from the input channel 11, thereby reducing the wear of the input section 10, thereby increasing the service life of the splitter. At the same time, the design of the first fillet 104 and the second fillet 105 can also reduce the accumulation and retention of the medium at the sharp corners, reduce the corrosion rate, and thus improve the corrosion resistance of the splitter.

[0041] Specifically, the maximum diameter of the diversion channel 21 is R 3 , R 3 ≥2mm. It can be understood that the diameter of the shunt channel 21 directly determines the flow rate of the fluid therein. Therefore, by limiting the diameter of the shunt channel 21, the flow rate of the fluid in the shunt channel 21 can be accurately controlled, thereby ensuring that the fluid enters each branch at an appropriate speed, thereby reducing the energy loss and fluid instability caused by the excessive flow rate of the fluid, thereby improving the stability and reliability of the diverter. At the same time, the diameter restriction of the shunt channel 21 also helps to control the flow in each shunt channel 21, ensuring a more uniform flow distribution, and avoiding excessive or insufficient flow in some channels, which affects the performance of the overall system.

[0042] The present invention also provides a method for processing an integrated flow divider, comprising the following steps:

[0043] S1. Processing a solid tube material to form a main flow channel 106 and a plurality of branch flow channels 21, wherein the main flow channel 106 and the plurality of branch flow channels 21 are connected;

[0044] S2, spinning the tube material at the main flow channel 106 to process the main flow channel 106 into an input channel 11 and a buffer cavity 12, wherein the input channel 11 and the plurality of branch flow channels 21 are connected through the buffer cavity 12, and the diameter of the input channel 11 is R1, and the diameter of the buffer cavity 12 is R 2 , R 2 >R 1 .

[0045] The basic principle of the spinning process is to install the metal preform to be processed on the core mold of the spinning machine, press it against the core mold through the tail top, and drive the metal preform at a certain speed under the drive of the spinning machine spindle. At the same time, the spinning wheel presses against the metal preform in a certain direction, causing plastic deformation at the contact point between the metal preform and the spinning wheel, thereby obtaining the required parts. Among them, the spinning process is simple and the production cost is low. It avoids the defects of the existing technology of segmented welding and pickling of the diverter causing pollution. At the same time, the amount of cutting in the production process is also small, and the material cost is low.

[0046] Further, the step S1 includes: S11, punching the solid pipe material to punch out the main flow channel 106 and a plurality of the branch flow channels 21 in the pipe material, wherein the maximum diameter of the branch flow channel 21 is R 3 , R 3 ≥5mm; or S12, first punching the solid tube material to punch out the main flow channel 106 in the tube material, and then drilling a plurality of branch flow channels 21, the maximum diameter of the branch flow channel 21 is R 3 , R 3 Understandably, when the diameter of the water diversion channel is less than 5 mm, the stamping process is difficult to process, so the punching process is replaced by the drilling process, thereby reducing the processing difficulty of the diversion channel 21, improving the production and processing efficiency of the diverter, and reducing the production cost of the diverter.

[0047] In one embodiment, the step S1 also includes a step S13, and the step S13 is located after the step S11 or the step S12; step S13, punching the tube material to punch out a weight-reducing hole 22 on the cavity wall of the mainstream channel 106, and the weight-reducing hole 22 is connected to the buffer cavity 12. By providing the weight-reducing hole 22, the material used in the diverter is reduced, thereby reducing the production and manufacturing cost of the diverter, and is also conducive to the lightweight of the diverter. Furthermore, the weight-reducing hole 22 is connected to the buffer cavity 12, so that it can play a role in buffering the flow of the fluid to a certain extent, and then when the fluid enters the buffer cavity 12 from the input channel 11, the design of the weight-reducing hole 22 optimizes the distribution and flow rate of the fluid, thereby helping to achieve a more uniform fluid distribution, thereby improving the diversion effect of the diverter.

[0048] In one embodiment, the step S1 includes: S14, punching the pipe material to punch out a positioning hole 23 at the end of the pipe material away from the input channel 11, and the positioning hole 23 is arranged opposite to the weight-reducing hole 22. By setting the positioning hole 23, the installation and limiting of the diverter are facilitated, thereby improving the installation efficiency of the diverter. It can be understood that the positioning hole 23 mainly serves to limit the radial direction of the diverter. At the same time, the positioning hole 23 and the weight-reducing hole 22 are arranged oppositely, and the central axis of the positioning hole 23 and the weight-reducing hole 22 are both located on the central axis of the diverter, so that the wall thickness of the same cross section of the diverter is always consistent, so that when the positioning hole 23 limits the diverter, the force in each direction is more uniform, thereby improving the stability and service life of the diverter.

[0049] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
