Abstract
Description
Technical Field
[0001] This utility model belongs to the field of heat exchanger technology, and specifically relates to an external spiral turbulence component. Background Technology
[0002] The distributor of a heat exchanger is a key component in the heat exchange system, mainly used to ensure uniform fluid distribution to improve heat exchange efficiency and system stability. It can evenly distribute the fluid (liquid or gas) entering the heat exchanger into each heat exchange tube or channel, avoiding flow deviation caused by uneven local flow.
[0003] In practical use, the fluid entering the distributor may be uneven, which directly affects the consistency and uniformity of subsequent distribution. However, in existing technologies, most distributors do not have corresponding flow-dispersing components at their upstream end, making it impossible to guarantee the uniformity of the fluid to be distributed. Utility Model Content
[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing an external spiral-type turbulence component.
[0005] To achieve the innovative objectives of this utility model, the following technical solutions can be used:
[0006] An external spiral turbulence assembly can be installed inside the input pipe of a distributor. It includes a cylindrical turbulence column, and a spiral turbulence structure is provided on the outer side wall of the turbulence column. A fluid channel is formed between the spiral turbulence structure and the inner wall of the input pipe.
[0007] The turbulence-dispersing component of this invention is installed in the input pipe and can turbulently mix the fluid to be distributed, ensuring the uniformity and consistency of subsequent distribution. Specifically, it is achieved through a spiral turbulence-dispersing structure, which is set between the outer wall of the turbulence-dispersing column and the inner wall of the input pipe. The fluid is conveyed backward in a spiral manner through the fluid channel. The rotation process helps to improve the mixing degree, and after flowing out of the fluid channel, the fluid may remain in a rotating state, which is conducive to further mixing of the various branches.
[0008] In the aforementioned external spiral turbulence assembly, the spiral turbulence structure includes a turbulence groove disposed on the outer wall of the turbulence column. The turbulence groove is radially recessed and extends spirally along the axial direction.
[0009] The turbulence channel is radially recessed on the outer wall of the turbulence column, and the channel extends spirally, which can guide the fluid passing through in a circumferential rotation, which is conducive to thorough mixing. Furthermore, from the axial direction, the openings at both ends of the turbulence channel do not overlap in a continuous manner.
[0010] In the aforementioned external spiral-shaped flow-dispersing assembly, at least three sets of flow-dispersing grooves are evenly distributed circumferentially. This helps ensure fluid flowability.
[0011] In the aforementioned external spiral-type turbulence assembly, the cross-section of the turbulence groove is semi-circular, square, or triangular. However, a semi-circular shape is preferred to avoid the problem of incomplete mixing caused by sharp corners.
[0012] In the aforementioned external spiral turbulence assembly, a fluid channel is formed between the inner wall of the input pipe and the turbulence groove, and the fluid channel extends spirally in the axial direction.
[0013] The fluid channel is formed between the inlet pipe and the turbulence channel. Its spiral extension allows the fluid to be transported backward by axial movement and circumferential rotation, ensuring a good mixing effect.
[0014] In the aforementioned external spiral turbulence assembly, the distributor includes a conical distribution section and an input pipe connected to the liquid inlet end of the distribution section, and the turbulence column is detachably fixed in the input pipe.
[0015] The baffle column and the input pipe are fixed in a flexible and detachable manner, making them easy to install and remove.
[0016] In the aforementioned external spiral turbulence assembly, the outer wall of the turbulence column is provided with an external thread, the inner wall of the input pipe is provided with an internal thread, the external thread and the internal thread are engaged, and the outer end face of the turbulence column is provided with a non-circular twisting part.
[0017] The spoiler column and the input pipe are detachably fixed by threaded engagement. The screwing part at the outer end is used to rotate the spoiler column. The specific forms can be common ones such as cross hole, slotted hole, external hexagon, internal hexagon, etc.
[0018] In the aforementioned external spiral turbulence assembly, the inner wall of the turbulence groove is provided with a turbulence thread, the spiral direction of the turbulence thread is adapted to the spiral direction of the internal thread, and a fluid channel is formed between the turbulence thread and the internal thread; the inner side wall of the inner end of the input pipe is provided with a positioning inner step, and the outer periphery of the inner end of the turbulence column abuts against the positioning inner step.
[0019] The turbulence column is tightened so that its inner end is tightly against the positioning inner step, and the tightening direction of the turbulence column is opposite to the spiral direction of the turbulence channel. When the fluid is input, it exerts an impact force on the sidewall of the turbulence channel, which can generate a component force in the tightening direction, preventing the turbulence column from automatically unscrewing. Moreover, turbulence threads are provided in the turbulence channel, which is equivalent to forming a threaded structure on the inner sidewall of the fluid channel, which can further turbulently mix the passing fluid.
[0020] In the aforementioned external spiral turbulence assembly, the inner wall of the inner end of the input pipe is provided with a positioning inner step, the inner end of the turbulence column abuts against the positioning inner step, a limiting piece is provided on the outer end face, a limiting groove is provided on the inner wall of the input pipe, and the front end of the limiting piece extends into the limiting groove.
[0021] As another way to detachably fix the spoiler column, the outer side of the inner end of the spoiler column abuts against the inner positioning step, and the outer end is limited by a limiting piece. The limiting piece is attached to the outer end face of the spoiler column, and the front end is inserted into the limiting groove to restrict the spoiler column from coming out.
[0022] In the aforementioned external spiral turbulence assembly, the limiting plate is detachably fixed to the outer end face of the turbulence column by at least two connecting bolts;
[0023] Alternatively, the outer end face of the turbulence column is provided with a radially extending groove with a T-shaped cross-section, the limiting piece slides in the groove and is connected to the elastic element, having a radially extending elastic tendency;
[0024] The positioning inner step is provided with an axially penetrating step notch, which corresponds to and communicates with the inner end of the fluid channel.
[0025] The limiting plate can be fixed using connecting bolts, resulting in a simple structure. The two connecting bolts are distributed along the length of the limiting plate, preventing rotation and effectively restricting both axial and circumferential movement of the turbulence column. Alternatively, the limiting plate can be positioned within a groove, utilizing an elastic element such as a spring to extend outwards, ensuring stable insertion into the groove. To allow only axial movement, the groove's cross-section can be T-shaped or other feasible shapes. A lever can be installed on the limiting plate, extending from the groove along the axial direction of the turbulence column for easy maneuvering and flexible assembly / disassembly. Since the limiting plate is located between the turbulence grooves, it does not obstruct the fluid channel, and the stepped notch prevents the positioning step from blocking fluid output from the fluid channel.
[0026] Compared with the prior art, the present invention has the following main advantages:
[0027] 1. The spiral turbulence structure is set between the outer wall of the turbulence column and the inner wall of the input pipe. The fluid is transported backward in a spiral manner through the fluid channel. The rotation process is conducive to improving the mixing degree. Moreover, after flowing out of the fluid channel, the fluid may remain in a rotating state, which is conducive to further mixing of the various branches.
[0028] 2. The turbulence column and the input pipe are detachably fixed by threaded engagement. The turbulence column is tightened so that its inner end is in close contact with the positioning inner step. Moreover, the tightening direction of the turbulence column is opposite to the spiral direction of the turbulence channel. When the fluid is input, it exerts an impact on the side wall of the turbulence channel. This impact can form a component force in the tightening direction, which can prevent the turbulence column from automatically unscrewing.
[0029] 3. A turbulence thread is provided in the turbulence channel. The turbulence thread plus the internal thread is equivalent to forming a threaded structure on the inner sidewall of the fluid channel, which can further turbulently mix the fluid passing through.
[0030] 4. The inner end of the spoiler column abuts against the positioning inner step, and the outer end is limited by a limiting plate. Two connecting bolts are distributed along the length of the limiting plate to prevent it from rotating. This allows the limiting plate to not only effectively restrict the axial movement of the spoiler column, but also to prevent its circumferential rotation.
[0031] 5. The limiting piece can also be set in the slide groove, and the elastic element can be used to obtain the tendency to extend outward, so as to ensure that the limiting piece is stably inserted into the limiting groove. Attached Figure Description

[0037] In the figure, the components are: distributor 1, input pipe 2, turbulence column 3, spiral turbulence structure 4, fluid channel 5, turbulence groove 6, distribution part 7, turning part 8, positioning inner step 9, limiting plate 10, limiting groove 11, connecting bolt 12, and step notch 13. Detailed Implementation
[0038] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0039] Example 1
[0040] Specific implementation examples Figures 1-3 As shown, the external spiral turbulence assembly can be installed inside the input pipe 2 of the distributor 1. It includes a cylindrical turbulence column 3, a spiral turbulence structure 4 on the outer wall of the turbulence column 3, and a fluid channel 5 formed between the spiral turbulence structure 4 and the inner wall of the input pipe 2.
[0041] Specifically, this turbulence-disrupting component is installed in the input pipe 2, which can turbulently mix the input fluid to ensure the uniformity and consistency of subsequent distribution. This is achieved through a spiral turbulence-disrupting structure 4, which is located between the outer wall of the turbulence-disrupting column 3 and the inner wall of the input pipe 2. The fluid is conveyed backward in a spiral manner through the fluid channel 5. The rotation process helps to improve the mixing degree, and after flowing out of the fluid channel 5, the fluid may remain in a rotating state, which is conducive to further mixing of the various branches.
[0042] like Figure 1 , Figure 3 As shown, the spiral turbulence structure 4 includes four turbulence grooves 6 evenly distributed circumferentially on the outer wall of the turbulence column 3. The turbulence grooves 6 are radially concave and extend spirally in the axial direction, and the cross-section of the turbulence grooves 6 is semi-circular. A fluid channel 5 is formed between the inner wall of the input pipe 2 and the turbulence grooves 6, and the fluid channel 5 extends spirally in the axial direction.
[0043] Specifically, the turbulence channel 6 is radially recessed on the outer wall of the turbulence column 3, and the channel extends spirally, which can guide the fluid passing through in a circumferential rotation, which is conducive to thorough mixing. Furthermore, from the axial direction, the openings at both ends of the turbulence channel 6 do not overlap in a continuous manner. The fluid channel 5 is formed between the input pipe 2 and the turbulence channel 6, and its spiral extension allows the fluid to be transported backward by axial movement and circumferential rotation, ensuring the mixing effect.
[0044] like Figure 2 , Figure 3 As shown, the distributor 1 includes a conical distribution section 7 and an input pipe 2 connected to the inlet end of the distribution section 7. A turbulence column 3 is detachably fixed in the input pipe 2. The outer wall of the turbulence column 3 has external threads, and the inner wall of the input pipe 2 has internal threads. The external and internal threads mesh with each other. A non-circular turning part 8 is provided on the outer end face of the turbulence column 3. A turbulence thread is provided on the inner wall of the turbulence groove 6, and the helical direction of the turbulence thread corresponds to the helical direction of the internal thread. A fluid channel 5 is formed between the turbulence thread and the internal thread. The inner end of the input pipe 2 has a radially protruding positioning inner step 9, and the outer periphery of the inner end of the turbulence column 3 abuts against the positioning inner step 9.
[0045] Specifically, the turbulence column 3 is flexibly detachable from the input pipe 2, facilitating assembly and disassembly. The turbulence column 3 and input pipe 2 are detachably fixed via threaded engagement. The outer end, a rotating part 8, is used to rotate the turbulence column 3; specifically, the rotating part 8 is an internal hexagonal hole. After the turbulence column 3 is tightened, its inner end is tightly against the positioning inner step 9, and the tightening direction of the turbulence column 3 is opposite to the spiral direction of the turbulence groove 6. When the fluid is input, it exerts an impact on the sidewall of the turbulence groove 6, creating a component force in the tightening direction, preventing the turbulence column 3 from automatically unscrewing. Furthermore, the turbulence groove 6 is provided with turbulence threads, equivalent to a threaded structure on the inner sidewall of the fluid channel 5, which further turbulently mixes the passing fluid.
[0046] Additionally, internal threads, external threads, and turbulence threads are not specifically shown in the figure.
[0047] The specific working principle is as follows: The fluid to be distributed is input from the front end of the input pipe 2. When it flows to the turbulence column 3, the fluid is dispersed into multiple streams and enters the fluid channel 5. It is then spirally conveyed backward. At the same time, the turbulence thread and internal thread cause each stream of fluid to rotate further. After flowing out of the fluid channel 5, each stream of fluid mixes again with its final rotation state. After being fully mixed, it is distributed and output backward from the distribution section 7.
[0048] Example 2
[0049] The working principle of this embodiment is basically the same as that of embodiment 1, except that the detachable fixing method of the turbulence column 3 is different.
[0050] Specific implementation examples Figure 4 , Figure 5 As shown, the inner wall of the inner end of the input pipe 2 is provided with a positioning inner step 9. The inner end of the turbulence column 3 abuts against the positioning inner step 9. A limiting piece 10 is provided on the outer end face between the turbulence grooves 6. A limiting groove 11 is provided on the inner wall of the input pipe 2. The front end of the limiting piece 10 extends into the limiting groove 11. The limiting piece 10 is detachably fixed to the outer end face of the turbulence column 3 by at least two connecting bolts 12. The positioning inner step 9 is provided with an axially penetrating step notch 13, which corresponds to and communicates with the inner end of the fluid channel 5.
[0051] Specifically, the outer side of the inner end of the spoiler column 3 abuts against the positioning inner step 9, and the outer end is limited by a limiting piece 10. The limiting piece 10 is in contact with the outer end face of the spoiler column 3, and its front end is inserted into the limiting groove 11 to prevent the spoiler column 3 from coming out. The limiting piece 10 is fixed by connecting bolts 12, which is simple in structure. Moreover, the two connecting bolts 12 are distributed along the length of the limiting piece 10, which can prevent its rotation. This allows the limiting piece 10 to not only effectively limit the axial movement of the spoiler column 3, but also prevent its circumferential rotation.
