Description

Technical Field

[0001] The invention relates to the technical field of heat exchange equipment, in particular to a heat exchanger fin tube with high heat conduction efficiency. Background Art

[0002] Heat exchanger finned tubes, also known as finned tubes or ribbed tubes, are a type of extended surface tube. By adding fins to the surface of the heat exchange tube, the heat transfer area is significantly increased, making heat transfer more efficient. This design is particularly suitable for scenarios requiring efficient heat exchange, such as heat exchange between air and liquid. When the hot fluid flows through the base tube, the heat is transferred to the fins through the tube wall. The fins then transfer the heat away through contact with the external medium.

[0003] Due to the existence of thermal resistance, it takes a certain amount of time for heat to be transferred from the fluid in the tube to the fin surface. Traditional fins, especially those with simple flat fins or simple corrugated fins, usually have a linear or planar heat dissipation path. After the heat is conducted out of the base tube, it mainly relies on the thickness and surface area of ​​the fin itself to dissipate the heat. The heat transfer path is relatively simple, and the heat dissipation mainly relies on direct convection and radiation between the outer surface of the fin and the air. There is no internal or more complex structure to enhance heat dispersion and transfer, and the heat dissipation efficiency is low. Summary of the Invention

[0004] The object of the present invention is to provide a heat exchanger fin tube with high heat conduction efficiency to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a heat exchanger fin tube with high heat conduction efficiency, comprising a heat exchange tube, a preset groove being provided on one side of the inner wall of the heat exchange tube, and a plurality of groups of insertable grooves being provided on the heat exchange tube, wherein the preset grooves and the insertable grooves are connected; An inner heat exchanger is movably connected to one side of the insertable slot near the inner side, and a U-shaped heat sink is movably connected to one side of the insertable slot near the outer side. A group of oblique deformable plates are welded to one side of the inner heat exchanger near the U-shaped heat sink. An embedded protrusion is provided on one side of the oblique deformable plate away from the inner heat exchanger. An oblique support reset plate supported on the inner wall of the oblique deformable plate is welded to one side of the inner heat exchanger near the U-shaped heat sink. A set of outer oblique positioning plates are welded to the side of the U-shaped heat sink close to the inner heat exchanger. The embedded protrusions are movably engaged in the grooves provided in the outer oblique positioning plates. The inner heat exchanger and the U-shaped heat sink are assembled by the structural coordination between the inner heat exchanger and the U-shaped heat sink. Heat exchange connecting plates are welded and fixed to the inner heat exchange component and the proximal side of the U-shaped heat dissipation plate, and the two heat exchange connecting plates are fixed by a heat exchange connecting sleeve.

[0006] Preferably, the two embedded protrusions are arranged away from each other.

[0007] Preferably, the obliquely deformable plate and the embedded protrusion are an integrally formed structure.

[0008] Preferably, the distance between the two outwardly inclined positioning plates gradually increases from the side close to the U-shaped heat dissipation plate to the side away from the U-shaped heat dissipation plate.

[0009] Preferably, a central heat sink is welded and fixed at the center of the inner wall of the U-shaped heat sink, a T-shaped heat sink is provided at one end of the central heat sink away from the U-shaped heat sink, and the central heat sink and the T-shaped heat sink are an integrally formed structure.

[0010] Preferably, side heat sinks are welded and fixed to both sides of the central heat sink, and the bent sides of the side heat sinks are welded and fixed to the side surfaces of the T-shaped heat sink.

[0011] Preferably, four inner assembly annular plates are movably installed on the inner side of the heat exchange tube, and the four inner assembly annular plates form a complete annular structure. Locking bolts are threadedly installed on the inner assembly annular plates, and the locking bolts are threadedly installed on the inner heat exchange component.

[0012] Preferably, a semicircular groove is provided at the edge of the inner assembly annular sheet, and the fitting parts of the two inner assembly annular sheets are combined to form a complete thread groove, and the thread groove is adapted to the locking bolt.

[0013] Preferably, a threaded groove is provided in the inner heat exchanger, a threaded pipe is connected to the thread in the threaded groove, a hexagonal nut is provided at the end of the threaded pipe not inserted into the threaded groove, a connecting pipe is fixedly installed at the end of the hexagonal nut away from the threaded pipe, a rotating sleeve is rotatably connected to the connecting pipe, a connecting liquid supply pipe is rotatably connected to the rotating sleeve, and the other end of the connecting liquid supply pipe is symmetrically provided with a rotating sleeve, a connecting pipe, a hexagonal nut and a threaded pipe.

[0014] Preferably, the rotating sleeve and the connecting pipe are fixedly welded, and both ends of the connecting liquid delivery pipe are provided with convex rings located inside the rotating sleeve and rotatably connected to the rotating sleeve.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The installation of components on the heat exchange tube is achieved by assembling the internal heat exchange parts and the U-shaped heat sink structure. The assembled structure enables the individual replacement of each accessory on the heat exchange tube. The U-shaped heat sink realizes the heat dissipation operation. The heat on the U-shaped heat sink is dissipated through the central heat sink, T-shaped heat sink, and side heat sink. The existence of multi-stage heat dissipation can achieve efficient heat exchange. When the components are aged, damaged or the performance degrades, the components can be removed and replaced separately without replacing the entire expensive heat exchanger fin tube, which greatly reduces maintenance costs and downtime. The central heat sink, T-shaped heat sink and side heat sink are arranged inside the U-shaped heat sink to form a three-dimensional, multi-stage heat transfer and dissipation path. These heat sinks greatly increase the contact area with the surrounding air, so that the heat can be dissipated more quickly and fully.

[0016] 2. Different effects can be achieved by choosing to install or not install the inner assembly annular sheet in the heat exchange tube. After installing the inner assembly annular sheet, the heat exchange tube is installed on the pipe that needs heat exchange by welding, and a relatively complete annular surrounding structure is formed inside the heat exchange tube. The larger annular surrounding structure can increase the contact area between the heat exchange tube and the pipe. You can also choose not to install the inner assembly annular sheet. This method can reduce the overall weight of the heat exchange tube and the components inside the heat exchange tube. The inner assembly annular sheet forms a larger annular surrounding structure inside the heat exchange tube. When the heat exchange tube is installed on the pipe that needs heat exchange by welding or other methods, this annular structure can ensure that the inner wall of the heat exchange tube and the outer wall of the pipe have a larger and more uniform contact area. The larger contact area means that the path for heat transfer from the pipe to the heat exchange tube is shorter and the contact is more complete, which reduces the contact thermal resistance and thus significantly improves the overall heat conduction efficiency.

[0017] 3. The installation of two threaded tubes realizes the connection between the two heat exchange tubes. The structure composed of the threaded tube and the connecting liquid delivery tube is a hollow structure, and hot water can be injected into its interior to achieve better and faster heat exchange. The threaded tube and the connecting liquid delivery tube together constitute a continuous, hollow channel, which directly becomes the path for the hot water to flow through. This means that heat can be transferred between the two heat exchange tubes through the flowing hot water, or continuously take away the absorbed heat and deliver the heat to the next heat exchange area, thereby improving the heat exchange speed.

DETAILED DESCRIPTION

[0031] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0032] See also Figure 1As for the threaded tube 12 in FIG. , the present invention provides a technical solution: a finned tube for a heat exchanger with high heat conduction efficiency, comprising a heat exchange tube 1, a preset groove 101 being provided on one side of the inner wall of the heat exchange tube 1, and a plurality of groups of insertable grooves 102 being provided on the heat exchange tube 1, and the preset grooves 101 and the insertable grooves 102 being connected; An inner heat exchanger 2 is movably connected to the inner side of the insertable slot 102, and a U-shaped heat sink 3 is movably connected to the outer side of the insertable slot 102. A group of obliquely deformable plates 201 are welded to the side of the inner heat exchanger 2 close to the U-shaped heat sink 3. An embedded protrusion 202 is provided on the side of the obliquely deformable plate 201 away from the inner heat exchanger 2. An oblique support reset plate 203 supported on the inner wall of the obliquely deformable plate 201 is welded to the side of the inner heat exchanger 2 close to the U-shaped heat sink 3. The embedded protrusion 202 is engaged in the groove body of the outer oblique positioning plate 301, which plays a role of precise positioning, ensuring that the inner heat exchanger 2 and the U-shaped heat dissipation plate 3 can be accurately in the designed relative position after being inserted into the insertable groove 102, avoiding installation deviation. The welding provides strong axial and radial fixing force, ensuring that the components will not easily loosen or shift when subjected to thermal stress, vibration or fluid impact. The design of the oblique deformable plate 201 is likely to play a guiding role during the insertion process, so that the inner heat exchanger 2 can be inserted into the vicinity of the U-shaped heat dissipation plate 3 more easily and accurately. After being inserted into place, the embedded protrusion 202 automatically snaps into the groove body. This is an obvious "in place" signal, which simplifies the assembly process, reduces the need for human judgment and adjustment, and improves the efficiency and consistency of mass production. When the heat exchanger is working, different components will produce different thermal expansion due to temperature changes. The slight deformation ability of the oblique deformable plate 201 can absorb part of the stress caused by thermal expansion and contraction, prevent the welding points or buckles from premature failure due to stress concentration, and improve the durability of the structure under temperature cycling.

[0033] A set of outer oblique positioning plates 301 are welded to the side of the U-shaped heat sink 3 close to the inner heat exchanger 2. The embedded protrusions 202 are movably engaged in the grooves provided on the outer oblique positioning plates 301. The inner heat exchanger 2 and the U-shaped heat sink 3 are assembled together through the structural coordination between the inner heat exchanger 2 and the U-shaped heat sink 3. The outer oblique positioning plate 301 and the groove thereon provide a precise guiding and positioning path for the embedded protrusion 202. When the inner heat exchanger 2 moves toward the U-shaped heat sink 3, the embedded protrusion 202 is guided into a specific groove position, ensuring that the two components are always assembled in the correct manner and angle, thus avoiding misalignment or deviation during installation. The engagement of the embedded protrusion 202 with the groove of the outer oblique positioning plate 301 provides an additional locking force, which helps to resist axial pull-out forces and ensure that the inner heat exchanger 2 will not easily slip out of the U-shaped heat sink 3, especially when subjected to vibration or thermal expansion and contraction stress.

[0034] When the inner heat exchanger 2 and the U-shaped heat sink 3 need to be assembled, first align the side of the inner heat exchanger 2 close to the U-shaped heat sink 3 (with the embedded protrusion 202) with the outer oblique positioning plate 301 on the U-shaped heat sink 3. The shape and position of the outer oblique positioning plate 301 are designed so that the embedded protrusion 202 can only move along a specific path. The shape of the protrusion 202 matches the groove body. This design plays a guiding role, ensuring that the inner heat exchanger 2 can be accurately moved to the correct position to avoid misalignment during installation.

[0035] The inner heat exchanger 2 and the U-shaped heat sink 3 are both welded with heat exchange connecting plates 4 on their near sides, and the two heat exchange connecting plates 4 are fixed by means of heat exchange connecting sleeves 5. The two ends of the heat exchange connecting sleeves 5 are respectively sleeved on the two heat exchange connecting plates 4. Each heat exchange connecting plate 4 is provided with corresponding holes or protrusions for the connecting sleeves 5 to pass through or position. After sleeved, the connecting sleeves 5 need to be fixed to the heat exchange connecting plates 4 by welding to prevent them from loosening or falling off. The welded sleeve fixation can ensure very good physical contact between the inner heat exchanger 2 and the U-shaped heat sink 3.

[0036] The two embedded protrusions 202 are arranged to be away from each other.

[0037] The obliquely deformable plate 201 and the embedded protrusion 202 are an integrally formed structure.

[0038] The one-piece molding structure refers to a one-time molding process in which the oblique deformable plate 201 and the embedded protrusion 202 are directly manufactured into a whole, without the need for subsequent splicing or assembly. This design has the following significant advantages: it reduces the connection interface, avoids the contact thermal resistance and stress concentration problems that may exist in traditional splicing, improves the overall stability of the structure, and enhances strength and reliability. Since there is no welding or bolt connection, the overall structure is more solid and not prone to loosening due to vibration or temperature changes, simplifying the production process. One-piece molding reduces processing steps, reduces production costs, and improves production efficiency. One-piece molding can better ensure the geometric accuracy between components, thereby improving heat transfer efficiency or other functional performance.

[0039] The distance between the two outer oblique positioning plates 301 gradually increases from the side close to the U-shaped heat dissipation plate 3 to the side far away from the U-shaped heat dissipation plate 3 .

[0040] A central heat sink 6 is welded and fixed at the center of the inner wall of the U-shaped heat sink 3. A T-shaped heat sink 7 is provided at one end of the central heat sink 6 away from the U-shaped heat sink 3, and the central heat sink 6 and the T-shaped heat sink 7 are an integrally formed structure.

[0041] The central heat sink 6 is welded and fixed at the center position of the inner wall of the U-shaped heat sink 3. The selection of this position is very critical because it is usually the area with the closest contact with the inner heat exchanger 2 and the most concentrated heat transfer. As the first bridge for heat transfer, the heat transferred from the inner heat exchanger 2 is first transferred to the inner wall of the U-shaped heat sink 3 through the contact surface, and then conducted more efficiently and more concentratedly through the welded central heat sink 6.

[0042] The T-shaped heat sink 7 is arranged at the end of the central heat sink 6 away from the U-shaped heat sink 3, which means that the T-shaped heat sink 7 extends from the central heat sink 6. The T-shaped horizontal bar part greatly increases the surface area of ​​the heat sink, and the vertical bar part is connected to the central heat sink 6, ensuring a good heat conduction path. The main function of the T-shaped heat sink 7 is to further expand the heat dissipation area. It will dissipate the heat conducted from the central heat sink 6 to the surrounding medium through its own surface area. The T-shaped structure may also provide certain structural support to enhance the stability of the central heat sink 6 in the extension direction.

[0043] The central heat sink 6 and the T-shaped heat sink 7 are manufactured as a whole, rather than being welded or assembled later. The one-piece molding eliminates the thermal resistance that may be introduced by welding or other connection methods, making the heat conduction from the central heat sink 6 to the T-shaped heat sink 7 more efficient and uniform.

[0044] The overall structure is more robust and less prone to stress concentration or failure at the joints, which may simplify the production process, improve production efficiency and product consistency, and make it easier to design complex and optimized heat sink shapes to maximize heat dissipation efficiency. Side heat sinks 8 are welded and fixed to both sides of the central heat sink 6 , and the bent sides of the side heat sinks 8 are welded and fixed to the side surfaces of the T-shaped heat sink 7 .

[0045] The side heat sinks 8 are welded and fixed on both sides of the central heat sink 6. The welding provides a firm connection and ensures good heat conduction. The bent sides of the side heat sinks 8 are welded and fixed on the sides of the T-shaped heat sink 7. The connection points are on the sides of the T-shaped heat sink 7, which means that the side heat sinks 8 do not extend directly from the central heat sink 6, but are connected through the "bridge" of the T-shaped heat sink 7.

[0046] Heat is transferred from the internal heat exchanger 2 to the inner wall of the U-shaped heat sink 3, and then conducted through the central fins 6. Some of this heat continues to dissipate outward through the T-shaped fins 7, while another portion is transferred through the sides of the T-shaped fins 7 to the welded side fins 8, from which it is then dissipated. The side fins 8 add additional surface area to the heat dissipation system. This increase in surface area is particularly significant if the side fins 8 themselves are curved or have a special shape. While the T-shaped fins 7 primarily expand the heat dissipation area in one direction, the side fins 8 can dissipate heat outward from the sides of the T-shaped fins 7, potentially directing heat in different directions or areas for more even heat distribution and preventing localized overheating. The attachment of the side fins 8 to the sides of the T-shaped fins 7 acts as a heat dissipation flap, helping to more efficiently utilize the heat conducted from the T-shaped fins 7. The addition of the side fins 8 also provides support for the overall structure, especially when subjected to external forces or vibrations.

[0047] Four inner assembly annular sheets 9 are movably installed inside the heat exchange tube 1 , and the four inner assembly annular sheets 9 form a complete annular structure. Locking bolts 10 are threadedly installed on the inner assembly annular sheets 9 , and the locking bolts 10 are threadedly installed on the inner heat exchange component 2 .

[0048] The removable mounting of the inner assembly annular plate 9 and its bolted connection to the inner heat exchange element 2 give the entire internal structure a high degree of modularity. If the inner heat exchange element 2 or the annular plate 9 needs to be replaced or repaired, they can be disassembled and reassembled relatively easily without replacing the entire heat exchange tube 1. The bolted connection provides a precise and repeatable fixing method, ensuring that the inner heat exchange element 2 is accurately and stably positioned within the heat exchange tube 1.

[0049] A semicircular groove is provided at the edge of the inner assembly annular piece 9 , and the fitting parts of the two inner assembly annular pieces 9 are combined to form a complete thread groove, and the thread groove is adapted to the locking bolt 10 .

[0050] A threaded groove 11 is provided in the inner heat exchanger 2, and a threaded pipe 12 is connected to the inner thread of the threaded groove 11. A hexagonal nut 13 is provided at the end of the threaded pipe 12 that is not inserted into the threaded groove 11. A connecting pipe 14 is fixedly installed at the end of the hexagonal nut 13 away from the threaded pipe 12. A rotating sleeve 15 is rotatably connected to the connecting pipe 14, and a connecting liquid supply pipe 16 is rotatably connected to the rotating sleeve 15. The other end of the connecting liquid supply pipe 16 is symmetrically provided with the rotating sleeve 15, the connecting pipe 14, the hexagonal nut 13 and the threaded pipe 12.

[0051] The hexagonal nut 13 is fixed to the end of the threaded tube 12 that is not inserted into the thread groove 11 , providing a torque transmission point for facilitating tightening or disassembling the threaded tube 12 .

[0052] The cooperation between the rotating sleeve 15 and the connecting liquid supply pipe 16 allows a certain angle of deflection. Under the conditions of installation error, thermal expansion and contraction or mechanical vibration, it can effectively absorb displacement and stress, extend the life of the system, and transport the heated water to multiple heat exchange tubes through the connecting liquid supply pipe 16 to form a continuous heat exchange path.

[0053] The rotating sleeve 15 is fixedly welded to the connecting pipe 14 , and both ends of the connecting liquid delivery pipe 16 are provided with convex rings located inside the rotating sleeve 15 and rotatably connected to the rotating sleeve 15 .

[0054] Working principle: The first step: different effects can be achieved by choosing to install the inner assembled annular sheet 9 or not in the heat exchange tube 1. After the inner assembled annular sheet 9 is installed, the heat exchange tube 1 is installed on the pipe that needs heat exchange by welding. A relatively complete annular surrounding structure is formed inside the heat exchange tube 1. The larger annular surrounding structure can increase the contact area between the heat exchange tube 1 and the pipe. When installing the inner assembled annular sheet 9, four inner assembled annular sheets 9 need to be placed separately in the heat exchange tube 1 in advance. Multiple inner assembled annular sheets 9 form a complete annular structure in the preset groove 101, and the multiple inner assembled annular sheets 9 are fixed by locking bolts 10. The locking bolts 10 are threadedly installed in the groove body pre-opened on the heat exchange tube 1 to realize the installation and fixation of the four inner assembled annular sheets 9. You can also choose not to install the inner assembled annular sheet 9, and realize the heat exchange of the pipe by contacting the inner heat exchange component 2 with the pipe. This method can reduce the overall weight of the heat exchange tube 1 and the components inside the heat exchange tube 1.

[0055] The second step: the installation of the components on the heat exchange tube 1 is realized by assembling the inner heat exchange member 2 and the U-shaped heat dissipation plate 3 structure. The assembled structure can realize the separate replacement of each accessory on the heat exchange tube 1. When the U-shaped heat dissipation plate 3 and the inner heat exchange member 2 are assembled, the oblique deformable plate 201 on the inner heat exchange member 2 moves between the two outer oblique positioning plates 301. During the movement of the oblique deformable plate 201, the oblique deformable plate 201 is deformed by the pressure exerted by the outer oblique positioning plates 301. The oblique deformable plate 201 is deformed and exerts pressure on the oblique support reset plate 203. The existence of the oblique support reset plate 203 ensures the restoration of the oblique deformable plate 201 after deformation. After the embedded protrusion 202 reaches the slotted position on the outer oblique positioning plate 301, the embedded protrusion 202 is engaged with the outer oblique positioning plate 301 to realize the outer oblique positioning plate 301 and the oblique deformable plate 201. After the internal heat exchange component 2 and the U-shaped heat sink 3 are assembled by snap-fit ​​connection, the two heat exchange connecting plates 4 are also connected by the heat exchange connecting sleeve 5. The heat received by the internal heat exchange component 2 is transferred to the oblique deformable plate 201, and then to the U-shaped heat sink 3 through the oblique deformable plate 201. At the same time, the internal heat exchange component 2 can also transfer heat to another heat exchange connecting plate 4 through the heat exchange connecting plate 4, and then to the U-shaped heat sink 3 through the heat exchange connecting plate 4. The heat dissipation operation is achieved through the U-shaped heat sink 3. The heat on the U-shaped heat sink 3 is transferred through the central heat sink 6. The central heat sink 6 transfers part of the heat to the T-shaped heat sink 7. The U-shaped heat sink 3 can also transfer part of the heat to the side heat sink 8, and further heat dissipation is achieved through the T-shaped heat sink 7 and the side heat sink 8. The heat dissipation operation and the existence of multi-stage heat dissipation can achieve efficient heat exchange.

[0056] Step 3: After multiple heat exchange tubes 1 are installed on the pipeline, the multiple heat exchange tubes 1 can be assembled to improve the assembly stability of the heat exchange tubes 1. A threaded tube 12 is installed on the threaded groove 11 on the inner heat exchange component 2. The threaded tube 12 is installed by twisting the hexagonal nut 13. After the threaded tube 12 is installed, another threaded tube 12 is installed. The installation of the two threaded tubes 12 realizes the connection between the two heat exchange tubes 1. During the installation of the threaded tube 12, the hexagonal nut 13 can be rotated to achieve installation. During the rotation of the hexagonal nut 13, the rotating sleeve 15 can rotate around the connecting liquid supply pipe 16 to ensure the installation of the hexagonal nut 13 and the threaded tube 12. The structure composed of the threaded tube 12 and the connecting liquid supply pipe 16 is a hollow structure, and hot water can be injected into its interior to achieve better and faster heat exchange.
