Description

Technical Field

[0001] This utility model belongs to the technical field of bathroom heating equipment, specifically relating to a segmented bathroom heating radiator. Background Technology

[0002] Bathroom radiators are core components for heating bathroom spaces, requiring a balance between heat dissipation efficiency and spatial adaptability. They are widely used in residential and commercial buildings. Current mainstream products mostly feature an integrated pipe design, consisting of two parallel vertical pipes fixedly connected to multiple horizontal heat dissipation pipes to form a single integrated heat dissipation unit. According to common industry specifications, the horizontal width of these pipes is generally 40cm-60cm, and the vertical height exceeds 100cm. By extending the vertical dimension, the heat dissipation area is increased to meet the vertical heat dissipation needs of bathrooms.

[0003] However, this integrated long-size structure has obvious technical defects in industrial applications, causing problems throughout the product's entire life cycle: 1. Preparation process: When welding long vertical pipes to horizontal pipes, stress concentration and insufficient positioning accuracy can easily lead to deviations in the straightness of the pipe body. In addition, the large longitudinal span makes it difficult to control the sealing of the connection, increasing the molding difficulty and scrap rate, and raising the manufacturing cost. At the same time, the anti-corrosion coating, powder coating and other surface treatments of long pipe bodies require large equipment, which places high demands on the production site and investment.

[0004] 2. Transportation: The integrated long-size radiator is bulky, and the packaging requires a customized anti-damage structure, resulting in high material consumption and low efficiency. During transportation, the protruding parts of the tube are easily deformed by collisions, especially the welded joints, which are prone to cracking, leading to heat dissipation failure and increasing logistics losses and after-sales costs.

[0005] 3. Installation: Bathroom spaces are often limited by building design. In older homes or small apartments, doorways and passageways are narrow, making it difficult to move long products into the home. In summary, the existing integrated long-size design has technical bottlenecks in terms of manufacturing adaptability, transportation safety, and installation convenience, and cannot meet the industry's requirements for low cost, high efficiency, and high reliability. There is an urgent need for a bathroom-type heating radiator technology solution with optimized structural dimensions. Utility Model Content

[0006] To address the problems and shortcomings of the existing technology, this utility model provides a segmented bathroom heating radiator. By segmenting the design, the size and weight of a single radiator are reduced, thus lowering the difficulty of manufacturing, transportation losses, and installation barriers. At the same time, it ensures the sealing of connections and structural stability, ensuring heat dissipation efficiency and meeting the industry's requirements for low cost, high efficiency, and high reliability.

[0007] This utility model is achieved through the following technical solution: A segmented bathroom heating radiator includes an upper heat dissipation unit and a lower heat dissipation unit that are split vertically, and a docking component for realizing a detachable and sealed connection between the upper heat dissipation unit and the lower heat dissipation unit. The upper heat dissipation unit includes two parallel and spaced upper vertical pipes, and multiple upper heat dissipation horizontal pipes that are spaced along the length of the upper vertical pipes and whose two ends are fixedly connected to the two upper vertical pipes respectively. The bottom end of each upper vertical pipe is integrally formed with a downwardly extending upper connecting pipe section. The lower heat dissipation unit includes two lower vertical pipes that correspond one-to-one with the upper vertical pipes, and multiple lower heat dissipation horizontal pipes that are spaced apart along the length of the lower vertical pipes and whose two ends are fixedly connected to the two lower vertical pipes respectively. The top of each lower vertical pipe has an integrally formed lower connecting pipe section that extends upward. The docking assembly includes a connecting pipe located inside the upper docking pipe section and the lower docking pipe section, and an annular seal embedded at the connection between the upper docking pipe section and the lower docking pipe section.

[0008] By vertically splitting traditional integrated radiators into upper and lower heat dissipation units, the size and weight of individual heat dissipation units can be significantly reduced, solving the technical challenges of long-length tubes from the manufacturing stage. On one hand, this reduces stress concentration during welding of long upper and lower vertical tubes to their corresponding horizontal heat dissipation tubes, minimizing tube straightness deviations due to insufficient positioning accuracy, thus lowering the scrap rate. Simultaneously, it eliminates the need for large processing equipment for surface treatment, reducing production space and initial investment barriers, making it suitable for the production needs of small and medium-sized enterprises. On the other hand, in terms of transportation, the split units do not require customized large-scale damage-resistant packaging, reducing packaging material consumption and packaging time, while also reducing the risk of collision deformation of protruding parts and cracking of weld joints, thus reducing logistics losses and after-sales maintenance costs. In terms of installation, the split units can easily pass through narrow doorways and passageways in old residential buildings or small apartments, avoiding structural modifications and significantly improving installation convenience. In addition, the connecting pipe in the docking assembly can achieve precise connection between the upper docking pipe section and the lower docking pipe section, while the annular seal can fill the gap at the connection between the two, providing double protection for the sealing reliability and structural stability after the segmented connection, ensuring that the heat dissipation medium does not leak, maintaining the original heat dissipation efficiency of the radiator, and breaking through the technical bottleneck of the existing integrated design from the perspective of the whole life cycle.

[0009] Furthermore, an upper limit step is provided between the upper vertical pipe and the upper connecting pipe section, and the inner diameter of the upper vertical pipe is larger than the inner diameter of the upper connecting pipe section; a lower limit step is provided between the lower vertical pipe and the lower connecting pipe section, and the inner diameter of the lower vertical pipe is larger than the inner diameter of the lower connecting pipe section. The top end of the connecting tube abuts against the end face of the upper limit step, and the bottom end of the connecting tube abuts against the end face of the lower limit step.

[0010] The upper limit step between the upper vertical pipe and the upper connecting pipe section, and the lower limit step between the lower vertical pipe and the lower connecting pipe section, combined with the structure that the inner diameter of the upper vertical pipe is larger than that of the upper connecting pipe section and the inner diameter of the lower vertical pipe is larger than that of the lower connecting pipe section, can achieve precise axial positioning of the connecting pipe. When the top end of the connecting pipe abuts against the end face of the upper limit step and the bottom end abuts against the end face of the lower limit step, the coaxiality of the upper and lower vertical pipes can be strictly guaranteed, avoiding uneven sealing gaps at the joint caused by pipe misalignment, thus preventing seal failure. At the same time, the abutment fit between the limit step and the end face of the connecting pipe can disperse the axial force to the step surface, rather than concentrating it at the joint gap. This effectively resists the thermal expansion and contraction stress caused by temperature changes of the heat dissipation medium during long-term use, as well as external impacts during installation or use, preventing loosening at the segmented connection and extending the service life of the radiator. In addition, this limiting structure does not require additional positioning tools, which simplifies the assembly process and improves assembly accuracy and efficiency.

[0011] Furthermore, the inner wall of the upper connecting pipe section is provided with an internal forward thread, and the inner wall of the lower connecting pipe section is provided with an internal reverse thread, and the pitch of the internal forward thread and the internal reverse thread are the same and the thread profile is the same. The outer wall of the connecting pipe is provided with an external reverse thread and an external forward thread at intervals along its axial direction. The external reverse thread is located directly above the external forward thread, and the external reverse thread is adapted to the internal forward thread on the inner wall of the upper connecting pipe section, while the external forward thread is adapted to the internal reverse thread on the inner wall of the lower connecting pipe section.

[0012] The inner forward thread on the inner wall of the upper connecting pipe section and the inner reverse thread on the inner wall of the lower connecting pipe section are matched with the outer reverse thread and outer forward thread on the outer wall of the connecting pipe. Furthermore, the inner forward and inner reverse threads have the same pitch and thread profile, allowing the rotation of the connecting pipe to drive the upper and lower connecting pipe sections to approach and lock synchronously along the axial direction, eliminating the need for separate operations on the upper and lower sections. This significantly reduces assembly time and improves assembly efficiency. The threaded connection structure offers excellent disassembly. When a single heat dissipation unit malfunctions, the upper and lower heat dissipation units can be separated by rotating the connecting pipe in the reverse direction, allowing for individual replacement or repair of the faulty unit without needing to replace the entire heat dissipation unit, thus reducing maintenance costs. Simultaneously, the threaded fit itself has self-locking properties, resisting vibration interference during use and preventing loosening of the threads at the segmented connection due to vibration. This further ensures connection stability and sealing reliability, preventing leakage of the heat dissipation medium.

[0013] Furthermore, the outer wall of the connecting pipe also has an annular transition section, which is located between the external reverse thread and the external forward thread. The outer diameter of the annular transition section is smaller than the outer diameter of the external reverse thread, and the axial length of the annular transition section is 2mm-10mm.

[0014] The annular transition section on the outer wall of the connecting pipe, located between the external counter-rotating thread and the external forward-rotating thread, has an outer diameter smaller than that of the external counter-rotating thread, creating a dedicated space for the seal installation. During assembly, the annular seal precisely embeds into the gap formed by the annular transition section and the inner walls of the upper and lower connecting pipe sections, preventing compression or friction between the seal and the threaded structure, thus preventing seal deformation and failure and ensuring a tight seal. Simultaneously, the annular transition section reduces the contact area between the connecting pipe and the inner walls of the upper and lower connecting pipe sections, lowering the frictional resistance during tightening and making assembly easier. Furthermore, the annular transition section disperses stress concentration at the connection point of the external counter-rotating thread and the external forward-rotating thread, preventing localized weakness in the connecting pipe due to abrupt changes in the thread structure, thus improving the overall structural strength of the connecting pipe and extending its service life.

[0015] Furthermore, the annular seal is a temperature- and water-resistant sealing ring, and the sealing ring is made of silicone. The sealing ring is located between the upper and lower connecting pipe sections, and the inner wall of the sealing ring abuts against the outer wall of the annular transition section.

[0016] The ring-shaped seal, made of temperature- and water-resistant silicone, possesses excellent elasticity, aging resistance, and resistance to water vapor erosion. It can adapt to the long-term temperature fluctuations and high humidity environment of bathroom spaces, preventing the seal from hardening and cracking due to temperature changes or mold growth and failure due to water vapor erosion, ensuring stable long-term sealing performance. Simultaneously, the sealing ring is located between the upper and lower connecting pipe sections, with its inner wall abutting against the outer wall of the annular transition section, forming a dual sealing structure of "connecting pipe section gap sealing + transition section outer wall contact sealing." This effectively prevents the heat dissipation medium from leaking from the joint, further improving sealing reliability. The easy processing of silicone material also reduces the production difficulty of the sealing ring, and precise assembly can be achieved without complex installation structures, balancing sealing effect and ease of assembly.

[0017] Furthermore, a strip-shaped rotating hole is provided inside the connecting pipe. An extended wrench can be used to screw the connecting pipe through the upper or lower vertical pipe. The strip-shaped rotating hole connects the upper and lower vertical pipes.

[0018] The strip-shaped perforation inside the connecting pipe serves two purposes. First, it provides an operating position for an extended wrench, allowing it to pass through either the upper or lower vertical pipe and directly into the perforation. This eliminates the need for additional operating space outside the radiator, preventing damage to the radiator's overall structure and appearance while adapting to the tool. Second, the extended wrench design reduces assembly difficulty, enabling precise tightening of the connecting pipe even in confined bathroom installation spaces, thus improving assembly efficiency. Furthermore, the perforation, penetrating the entire connecting pipe, directly connects the upper and lower vertical pipes, ensuring smooth flow of the heat dissipation medium through both sections without obstruction, thus preserving the overall heat dissipation efficiency of the radiator.

[0019] Furthermore, the annular seal is a sealant, which is filled between the upper and lower connecting pipe sections.

[0020] By using an annular sealant to fill the gap between the upper and lower connecting pipe sections, the sealant's fluidity can fill all the tiny gaps between the two sections, forming a seamless seal. Compared to traditional sealing rings, this sealant is more adaptable to machining errors at the mating surfaces, preventing leaks caused by uncovered gaps and significantly improving sealing reliability. Furthermore, the sealant has lower requirements for the machining precision of the mating surfaces, eliminating the need for strict control over the flatness of the end faces of the upper and lower connecting pipe sections, thus reducing the difficulty of pipe processing and production costs. Simultaneously, the sealant, suitable for bathroom heating environments, possesses excellent water and temperature resistance, and is not prone to aging or peeling even after long-term contact with heat dissipation media and bathroom moisture, reducing the risk of seal failure and lowering the frequency and cost of subsequent maintenance.

[0021] Furthermore, the upper connecting pipe section has the same thickness as the upper vertical pipe section, the outer diameter of the upper connecting pipe section is larger than the outer diameter of the upper vertical pipe section, and there is a transition pipe section between the upper connecting pipe section and the upper vertical pipe section. The lower connecting pipe section has the same thickness as the lower vertical pipe section, and the outer diameter of the lower connecting pipe section is larger than the outer diameter of the lower vertical pipe section. There is a transition pipe section between the upper connecting pipe section and the upper vertical pipe section.

[0022] The upper connecting pipe section has the same thickness as the upper vertical pipe section, ensuring consistent load-bearing and deformation resistance between the two sections. This avoids localized stress concentration due to thickness differences and prevents cracking at the joint during long-term use. The outer diameter of the upper connecting pipe section is larger than that of the upper vertical pipe section, increasing the contact area between the upper and lower connecting pipe sections, improving structural stability after connection, and reducing stress deformation at the joint. The transition pipe section between the upper connecting pipe section and the upper vertical pipe section allows for a smooth transition in pipe diameter from the vertical pipe to the connecting pipe section, avoiding increased flow resistance caused by abrupt changes in pipe diameter. It also further disperses structural stress, preventing fatigue damage at the joint due to structural abrupt changes. Similarly, the same design for the lower connecting pipe section achieves the same effect, resulting in a natural overall structural transition and enhancing the overall appearance and aesthetics of the radiator.

[0023] Furthermore, the connecting pipe is assembled between the upper and lower connecting pipe sections using a cold extrusion process.

[0024] The connecting pipe is assembled between the upper and lower connecting pipe sections using a cold extrusion process, eliminating the need for additional bolts, nuts, or adhesives, thus simplifying the assembly process and significantly improving efficiency. During cold extrusion, the connecting pipe forms a tight interference fit with the inner walls of the two connecting pipe sections, resulting in a fit strength far exceeding that of traditional threaded connections or adhesives. This effectively resists external impacts and media pressure, enhancing the stability of the connection structure. Furthermore, the cold extrusion process eliminates the need for high-temperature heating, preventing damage to the anti-corrosion coatings or powder coatings on the surfaces of the upper and lower connecting pipe sections. This avoids a decrease in the pipe's anti-corrosion performance due to processing, extending the overall service life of the radiator. In addition, the cold-extruded assembly provides excellent sealing, reducing the risk of heat dissipation medium leakage and ensuring the safe operation of the radiator.

[0025] Furthermore, sealing sleeves are provided on the outer sides of the upper and lower connecting pipe sections.

[0026] Installing sealing sleeves on the outer sides of the upper and lower connecting pipe sections creates a double-seal structure on top of the existing annular seal, further enhancing the sealing reliability at the joint. Even if the internal annular seal experiences minor failure, the sealing sleeves can prevent the heat dissipation medium from leaking outwards, improving safety. Simultaneously, the sealing sleeves completely cover the connection area of ​​the two connecting pipe sections, protecting the internal connecting pipes, threaded structures, and annular seals from external impacts, dust accumulation, and moisture erosion, reducing wear on internal components and extending the service life of the connecting components. Furthermore, the sealing sleeves conceal gaps and connection structures at the joint, resulting in a smoother and more uniform external appearance of the radiator, enhancing the product's aesthetics and market competitiveness.

[0027] The beneficial effects of this utility model are: This segmented bathroom heating radiator breaks through the technical bottleneck of traditional integrated long-size radiators from the perspective of the entire product life cycle through the collaborative design of "segmented structure + precise docking components", and achieves multi-dimensional performance optimization.

[0028] In the manufacturing process, the radiator is divided into an upper heat dissipation unit and a lower heat dissipation unit, which greatly reduces the size and weight of a single unit. This not only reduces stress concentration when the upper and lower vertical pipes are welded to the upper and lower horizontal heat dissipation pipes respectively, but also reduces the deviation in pipe straightness caused by insufficient positioning accuracy, effectively reducing the scrap rate. Furthermore, it eliminates the need for large processing equipment for surface treatment processes such as anti-corrosion coating and powder coating, significantly reducing the production site and initial investment threshold, and making it suitable for the production needs of small and medium-sized enterprises.

[0029] During transportation, the disassembled units do not require customized large-scale damage-resistant packaging, reducing the consumption of packaging materials and packaging time. At the same time, it avoids the problems of long tubes being easily deformed by collisions and welded joints being easily cracked, greatly reducing logistics losses and subsequent after-sales maintenance costs.

[0030] During installation, the upper and lower heat dissipation units can be transported separately, easily passing through narrow doorways and passageways in older residences or small apartments, without requiring structural modifications, greatly improving installation convenience. Regarding structural reliability and sealing performance, the connecting components play a crucial role: the connecting pipes, through adaptive connections with the upper and lower connecting pipe sections (such as threaded fit or cold extrusion assembly), combined with the precise positioning of the upper and lower limit steps, ensure the coaxiality of the upper and lower vertical pipes, dispersing axial forces to resist thermal expansion and contraction and external impacts, preventing loosening at the connection; the annular seal (silicone sealing ring or sealant) adapts to the temperature and humidity environment of the bathroom, effectively preventing leakage of the heat dissipation medium through a double sealing structure (such as the sealing ring abutting against the annular transition section, and sealant filling the gaps). Simultaneously, the annular transition section avoids interference between the seal and the threads, the strip-shaped rotating hole adapts to the extended wrench to improve assembly efficiency without affecting media flow, and the outer sealing sleeve further provides protection, protecting the internal connection structure from impact and moisture erosion and optimizing the appearance.

[0031] Furthermore, segmented bathroom heating radiators combine ease of use and maintenance with economy. The detachable design, such as threaded connections, allows for individual replacement and repair of faulty upper or lower heating units without the need for complete replacement. The stable connection through cold extrusion or threaded fit, along with the protection of anti-corrosion coating, extends the product's service life. Ultimately, this achieves a comprehensive advantage of low manufacturing cost, low transportation loss, high installation efficiency, and high reliability, fully meeting the core requirements of bathroom heating equipment for heat dissipation efficiency, space adaptability, and full-cycle economy.

[0042] In one embodiment, a segmented bathroom-type heating radiator includes an upper heat dissipation unit 1 and a lower heat dissipation unit 2, which are split vertically, and a docking assembly 3 that enables a detachable and sealed connection between the two. In the upper heat dissipation unit 1, two parallel and spaced upper vertical pipes 11 are distributed with multiple upper horizontal heat dissipation pipes 12 at intervals along their length.

An upper limit step 14 is provided between the upper vertical pipe 11 and the upper connecting pipe section 13. The inner diameter of the upper vertical pipe 11 is larger than the inner diameter of the upper connecting pipe section 13. The inner wall of the upper connecting pipe section 13 is provided with an internal positive spiral thread 131. The upper connecting pipe section 13 has the same thickness as the upper vertical pipe 11 but a larger outer diameter. A transition pipe section 15 is provided between the two. The lower heat dissipation unit 2 is structurally compatible with the upper heat dissipation unit 1. Two lower vertical pipes 21 correspond one-to-one with the upper vertical pipe 11. Multiple lower horizontal heat dissipation pipes 22 are fixedly connected to the two lower vertical pipes 21 at both ends. The top of each lower vertical pipe 21 is integrally formed with an upwardly extending lower connecting pipe section 23. A lower limit step 24 is provided between the lower vertical pipe 21 and the lower connecting pipe section 23. The inner diameter of the lower vertical pipe 21 is larger than the inner diameter of the lower connecting pipe section 23. The inner wall of the lower connecting pipe section 23 is provided with an internal reverse thread 231. The pitch of the internal forward thread 131 and the internal reverse thread 231 are the same and the thread profile is the same. The lower connecting pipe section 23 has the same thickness as the lower vertical pipe 21 but a larger outer diameter. A transition pipe section 15 is provided between the two.

[0043] In the docking assembly 3, the connecting pipe 31 is located inside the upper docking pipe section 13 and the lower docking pipe section 23. Its top end abuts against the end face of the upper limit step 14, and its bottom end abuts against the end face of the lower limit step 24. The outer wall of the connecting pipe 31 is provided with an external reverse thread 311 and an external forward thread 312 spaced apart along the axial direction. The external reverse thread 311 is located directly above the external forward thread 312. The external reverse thread 311 is adapted to the internal forward thread 131 of the upper docking pipe section 13, and the external forward thread 312 is adapted to the internal forward thread 131 of the upper docking pipe section 13. The lower connecting pipe section 23 has an internal reverse thread 231 for fitting; the outer wall of the connecting pipe 31 also has an annular transition section 313, which is located between the external reverse thread 311 and the external forward thread 312, and its outer diameter is smaller than that of the external reverse thread 311; the connecting pipe 31 has a strip-shaped rotating hole 314 inside, which connects the upper vertical pipe 11 and the lower vertical pipe 21.

[0044] During assembly, first, place the silicone sealing ring 321 on the outside of the annular transition section 313 of the connecting pipe 31. Then, insert the top of the connecting pipe 31 into the upper connecting pipe section 13, and then align the lower connecting pipe section 23 with the bottom of the connecting pipe 31. Use an extended wrench to pass through the upper vertical pipe 11 and insert it into the strip-shaped rotating hole 314. Rotate the connecting pipe 31 clockwise. Due to the thread direction design, the upper connecting pipe section 13 and the lower connecting pipe section 23 approach each other synchronously until the top of the connecting pipe 31 abuts against the upper limit step 14 and the bottom abuts against the lower limit step 24, thus pressing the sealing ring 321 to achieve a seal. Finally, put the sealing sleeve 4 on the outside of the two connecting pipe sections (the sealing sleeve is put on the outside of the upper vertical pipe 11 or the lower vertical pipe 21 in advance) to complete the assembly.
