Abstract
Description
Technical Field
[0001] This utility model belongs to the field of heat exchanger technology, and specifically relates to an internally threaded turbulence-disrupting 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 internally threaded turbulence component.
[0005] To achieve the innovative objectives of this utility model, the following technical solutions can be used:
[0006] An internally threaded flow-dispersing assembly includes a cylindrical body, with its two ends connected to a distributor and an inlet pipe, respectively, and a spiral flow-dispersing structure provided inside the cylindrical body.
[0007] This utility model discloses an internally threaded flow-dispersing component positioned between the inlet pipe and the distributor. It turbulently directs the fluid output from the inlet pipe to the distributor, which then distributes it to subsequent parts. The flow-dispersing component ensures uniform mixing of the fluid output from the inlet pipe, guaranteeing the evenness and consistency of subsequent distribution. The main part of the flow-dispersing component is a cylindrical body with an axially extending inner cavity. A spiral flow-dispersing structure is installed within this cavity, which guides the passing fluid in a spiral rotation, ensuring fluid uniformity.
[0008] In the aforementioned internal thread type turbulence assembly, the spiral turbulence structure includes a turbulence groove disposed on the inner wall of the cylindrical body, and the turbulence groove extends spirally.
[0009] The turbulence channel extends in a spiral shape, similar to an internal thread structure. It treats the fluid passing through it as approximately cylindrical. The turbulence channel can disturb the fluid from the radial outside, causing the fluid to twist and flow downstream from the outside in, ensuring uniform mixing.
[0010] In the aforementioned internal thread type turbulence assembly, the turbulence groove has at least two turns.
[0011] Setting multiple loops helps ensure sufficient turbulence.
[0012] In the aforementioned internally threaded turbulence assembly, the inner wall of the cylindrical body is provided with spirally extending turbulence ribs, and the turbulence grooves are formed between the turbulence ribs.
[0013] The turbulence channel is formed between adjacent turbulence ribs. The turbulence ribs protrude from the inner wall of the cylindrical body, making the cross-sectional flow rate of the spiral turbulence structure smaller than the cross-sectional flow rate of the inner cavity of the cylindrical body. This ensures that after the fluid is input from the upstream end of the cylindrical body, it can fully enter the spiral turbulence structure and ensure the turbulence effect of the turbulence channel.
[0014] In the aforementioned internally threaded turbulence assembly, the cylindrical body is provided with a detachably mounted cylindrical turbulence member, the outer wall of the turbulence member is in contact with the inner wall of the cylindrical body, and the turbulence member is provided with the turbulence groove.
[0015] The turbulence channel is set inside the cylindrical body by turbulence components, and the turbulence components are fixed in a flexible and detachable manner, making them easy to assemble and disassemble.
[0016] In the aforementioned internal thread type spoiler assembly, the cylindrical body is provided with an annular step, one end of the spoiler abuts against the annular step, and the other end abuts against the external thread nut. The external thread nut is screwed to the inner wall of the cylindrical body, and an axially extending anti-rotation protrusion and anti-rotation groove are provided between the inner wall of the cylindrical body and the outer wall of the spoiler.
[0017] The annular step is used to position the spoiler, the external thread nut is used to limit the spoiler and lock it in the cylindrical body, and the anti-rotation protrusion slides in the anti-rotation groove to prevent the spoiler from rotating circumferentially.
[0018] In the aforementioned internal thread type spoiler assembly, a limiting screw hole is provided through the side wall of the cylindrical body, and a set screw is provided in the limiting screw hole. The front end of the set screw abuts against the outer side wall of the spoiler, and a sealing ring is provided between the head of the set screw and the outer side wall of the cylindrical body.
[0019] As another method of fixing the spoiler, the limiting screw passes through the limiting screw hole, with its front end abutting against the outer wall of the spoiler, achieving limiting through friction. Furthermore, a limiting blind hole can be provided on the outer wall of the spoiler, with the front end of the limiting screw extending into the limiting blind hole to achieve circumferential and axial limiting fixation. The sealing ring is fitted onto the set screw and clamped between the inner side of the limiting screw head and the outer side of the cylindrical body, sealing the gap between the set screw and the limiting screw hole.
[0020] In the aforementioned internally threaded turbulence assembly, a turbulence cone is coaxially disposed inside the downstream end of the cylindrical body, with the tip of the turbulence cone facing the spiral turbulence structure. A liquid-passing gap is formed between the turbulence cone and the cylindrical body, and the turbulence cone is connected to the inner wall of the cylindrical body via a connecting rod.
[0021] The turbulence cone is located downstream of the helical turbulence structure. The fluid is first turbulent by the rotation of the helical structure, and then radially turbulent by the turbulence cone. Since the rotational turbulence directly disturbs only the radially outer fluid, while the inner fluid is only slightly disturbed (i.e., the disturbance level is relatively low), the turbulence cone can further mix and turbulent the inner and outer fluids, ensuring the turbulence effect. An annular liquid passage gap exists between the large-diameter end of the turbulence cone and the inner wall of the cylindrical body, ensuring smooth fluid passage. The turbulence cone is fixedly connected to the cylindrical body by several circumferentially distributed and radially extending connecting rods, providing good fixation with minimal impact on fluid flow.
[0022] In the aforementioned internally threaded turbulence assembly, the cylindrical body includes a main body section and connecting sections located at both ends of the main body section. The two connecting sections are respectively sleeved on the liquid outlet end of the liquid inlet pipe and the liquid inlet end of the distributor. The main body section is provided with the aforementioned spiral turbulence structure.
[0023] The connecting sections at both ends of the cylindrical body are connected to the inlet pipe and the distributor through an outer sleeve. Compared with the internal connection method, it is not necessary to set the connecting section with a very small outer diameter in order to adapt to the inner diameter of the inlet or outlet end, thus avoiding affecting the fluid flow.
[0024] In the aforementioned internal thread type turbulence assembly, the connecting section is connected to the liquid outlet and liquid inlet respectively by threads, tight fit, or adhesive bonding.
[0025] The connection section and the liquid outlet end can be achieved through methods including but not limited to threaded connection, tight fit insertion, and bonding fixation after insertion, which can be selected according to actual needs.
[0026] Compared with the prior art, the present invention has the following main advantages:
[0027] 1. The inner cavity of the cylindrical body is equipped with a spiral turbulence structure, which can guide the fluid in a spiral rotation to ensure the uniformity of the fluid.
[0028] 2. The spiral extension of the turbulence channel is similar to the structure of an internal thread. The turbulence channel can disturb the fluid from the radial outside, driving the fluid to twist and flow downstream from the outside in, ensuring uniform mixing.
[0029] 3. The turbulence channel is formed between adjacent turbulence ribs. The turbulence ribs protrude from the inner wall of the cylindrical body, so that the cross-sectional flow rate of the spiral turbulence structure is less than the cross-sectional flow rate of the inner cavity of the cylindrical body. This ensures that after the fluid is input from the upstream end of the cylindrical body, it can fully enter the spiral turbulence structure and ensure the turbulence effect of the turbulence channel.
[0030] 4. The turbulence channel is set inside the cylindrical body by turbulence components. The turbulence components are fixed in a flexible and detachable manner, making them easy to disassemble and assemble.
[0031] 5. The turbulence cone is located downstream of the spiral turbulence structure. The fluid is first turbulent by the spiral turbulence structure and then radially turbulent by the turbulence cone. The turbulence cone can further mix and turbulent the fluid on the inside and outside, ensuring the turbulence effect.
[0032] 6. The connecting sections at both ends of the cylindrical body are connected to the inlet pipe and the distributor by means of an outer sleeve to avoid affecting the fluid flow. Attached Figure Description

[0039] 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.
[0040] Example 1
[0041] Specific implementation examples Figures 1-3As shown, this internal thread type turbulence assembly includes a cylindrical body 1, with both ends of the cylindrical body 1 connected to a distributor 2 and an inlet pipe 3, respectively. The cylindrical body 1 is provided with a spiral turbulence structure 4.
[0042] Specifically, this internally threaded turbulence assembly is located between the inlet pipe 3 and the distributor 2. Its main part is a cylindrical body 1, which has an axially extending inner cavity. A spiral turbulence structure 4 is provided in the inner cavity, which can guide the fluid through the flow in a spiral rotation to ensure the uniformity of the fluid.
[0043] like Figure 2 , Figure 3 As shown, the spiral turbulence structure 4 includes multiple turbulence grooves 5 disposed on the inner wall of the cylindrical body 1, the turbulence grooves 5 extending spirally. The inner side wall of the cylindrical body 1 is provided with spirally extending turbulence ribs 6, and turbulence grooves 5 are formed between the turbulence ribs 6.
[0044] Specifically, the turbulence channel 5 extends spirally, resembling an internal thread structure. The fluid passing through it is approximated as cylindrical. The turbulence channel 5 agitates the fluid radially outward, causing it to twist and flow downstream from the outside inward, ensuring uniform mixing. The turbulence channel 5 is formed between adjacent turbulence ribs 6, which protrude from the inner wall of the cylindrical body 1. This ensures that the cross-sectional flow rate of the spiral turbulence structure 4 is less than the cross-sectional flow rate of the inner cavity of the cylindrical body 1, guaranteeing that the fluid, after being input from the upstream end of the cylindrical body 1, can fully enter the spiral turbulence structure 4, thus ensuring the turbulence effect of the turbulence channel 5.
[0045] In this embodiment, the cylindrical body 1 includes a main body section 14 and connecting sections 15 located at both ends of the main body section 14. The two connecting sections 15 can be respectively sleeved on the liquid outlet end 16 of the liquid inlet pipe 3 and the liquid inlet end 17 of the distributor 2, and are fixed by threads. The main body section 14 is provided with a spiral turbulence structure 4.
[0046] Specifically, the connecting sections 15 at both ends of the cylindrical body 1 are connected to the inlet pipe 3 and the distributor 2 by means of an outer sleeve. Compared with the internal connection, it is not necessary to set the connecting section 15 to a structure with a very small outer diameter in order to adapt to the inner diameter of the inlet or outlet end, so as to avoid affecting the fluid flow.
[0047] Specific working principle: During installation, the upstream end of the cylindrical body 1 is sleeved and screwed onto the outlet end 16 of the inlet pipe 3, and the downstream end is sleeved and screwed onto the inlet end 17 of the distributor 2. In use, the liquid to be distributed is input through the inlet pipe 3. The liquid flows into the cylindrical body 1 from the outlet end 16. When passing through the turbulence groove 5, the liquid on the radially outer side is spirally rotated and guided. This liquid further drives the inner part of the fluid to rotate. During the rotation process, the uniformity of liquid mixing is improved. Then, the liquid flows into the distributor 2 from the inlet end 17 and is distributed to subsequent parts by the distributor 2.
[0048] Example 2
[0049] The working principle of this embodiment is basically the same as that of embodiment 1. The difference is that the turbulence groove 5 is set in the cylindrical body 1 by an independent turbulence component 7.
[0050] Specific implementation examples Figure 4 As shown, a cylindrical body 1 is provided with a detachably mounted cylindrical baffle 7. The outer wall of the baffle 7 is in contact with the inner wall of the cylindrical body 1, and a baffle groove 5 is provided inside the baffle 7. An annular step 8 is provided inside the cylindrical body 1. One end of the baffle 7 abuts against the annular step 8, and the other end abuts against an externally threaded nut 9. The externally threaded nut 9 is screwed to the inner wall of the cylindrical body 1. An axially extending anti-rotation protrusion 10 and an anti-rotation groove 11 are provided between the inner wall of the cylindrical body 1 and the outer wall of the baffle 7.
[0051] Specifically, the turbulence groove 5 is set inside the cylindrical body 1 by the turbulence component 7. The turbulence component 7 is flexibly detachable, making it easy to assemble and disassemble. The annular step 8 is used to position the installation position of the turbulence component 7, and the external thread nut 9 is used to limit the turbulence component 7, locking it inside the cylindrical body 1. The anti-rotation protrusion 10 slides in the anti-rotation groove 11, preventing the circumferential rotation of the turbulence component 7.
[0052] Example 3
[0053] The working principle of this embodiment is basically the same as that of embodiment 1, except that a turbulence cone 12 is also provided inside the cylindrical body 1.
[0054] Specific implementation examples Figure 5 As shown, a turbulence cone 12 is coaxially disposed inside the downstream end of the cylindrical body 1. The tip of the turbulence cone 12 faces the spiral turbulence structure 4. A liquid passage gap 13 is formed between the turbulence cone 12 and the cylindrical body 1. The turbulence cone 12 is connected to the inner wall of the cylindrical body 1 by three circumferentially distributed and radially extended connecting rods 18.
[0055] Specifically, the turbulence cone 12 is located downstream of the spiral turbulence structure 4. The fluid is first turbulent by the spiral turbulence structure 4, and then radially turbulent by the turbulence cone 12. Since the rotating turbulence directly disturbs only the radially outer fluid, while the inner fluid is disturbed, i.e., the degree of disturbance is relatively low, the turbulence cone 12 can further mix and disturb the inner and outer fluids, ensuring the turbulence effect. There is an annular liquid passage gap 13 between the large-diameter end of the turbulence cone 12 and the inner wall of the cylindrical body 1, ensuring the smooth passage of the fluid.
