Description

Technical Field

[0001] This utility model relates to the field of heating equipment technology, and in particular to a detachable, weld-free heating radiator. Background Technology

[0002] In modern architecture, heating radiators, as important heat transfer devices, are widely used in residential, commercial, and industrial buildings. Radiators conduct heat to the surrounding environment through media such as water or steam to increase indoor temperature and ensure people's comfort. However, traditional heating radiators have some unavoidable drawbacks in installation, use, and maintenance, which directly affect system efficiency and maintenance costs.

[0003] Traditional heating radiators are typically installed using welded or threaded connections. While this structure ensures a stable connection between the radiator and the heating pipe system, it also presents some inconveniences. Especially when equipment malfunctions and requires repair or replacement, the traditional design makes disassembly extremely complex. In case of radiator failure, repair personnel need to use specialized tools to disassemble the radiator, sometimes even damaging the original structure. This disassembly method is not only time-consuming and labor-intensive but also increases maintenance costs.

[0004] Disassembly of traditional radiators is complex during maintenance, especially in older buildings where the piping system is more intricate and narrow, making disassembly even more difficult. In some cases, maintenance personnel may need to extensively alter the piping system, or even remove walls or floors, significantly increasing maintenance costs and placing a substantial financial burden on users.

[0005] Besides the disassembly issues, traditional radiators are also inconvenient for routine maintenance. Over time, dust and debris accumulate on the surface and inside the radiator, reducing its cooling efficiency. Because traditional radiators are installed in a fixed manner, cleaning requires disassembly, which is time-consuming and laborious, especially in confined spaces. Users may therefore neglect regular cleaning of the radiators, affecting the normal operation of the equipment.

[0006] In summary, the design of existing heating radiators presents significant challenges and costs in terms of disassembly, maintenance, and cleaning, impacting user convenience and experience. Therefore, designing a heating radiator that can be quickly disassembled, easily installed, and without welding has become a pressing technical challenge in this field. Solving this problem would significantly reduce maintenance and replacement costs, improve equipment versatility, and enhance user convenience, especially in older buildings, reducing space modifications required for maintenance and improving the overall economy and efficiency of the system. Utility Model Content

Detailed Implementation

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] Reference Figures 1-7 One embodiment of this utility model is a detachable, weld-free heating radiator, comprising:

[0044] Heating pipe 1 is used to connect to the house heating pipe system to realize the input of heat and the discharge of circulating water. Heating pipe 1 includes at least two sets, one set of which is connected to the heating pipe of the house heating system and the other set of which is connected to the drain pipe of the house heating system. The two sets of heating pipe 1 are interconnected to realize the circulation of the heating system.

[0045] The heat dissipation component 2, after being connected to the heating pipe 1, works with the heating pipe to achieve indoor heating. After the heat dissipation component 2 is connected to the heating pipe 1, the hot water in the heating system enters through the heating pipe 1 and is injected into the interior of the heating pipe 1. The heat dissipation structure of the heat dissipation component 2 is used to dissipate the heat in the heating system into the room, thereby completing the heating of the room. This principle is a common existing technology, and will not be elaborated on here.

[0046] Please see the appendix Figure 3 Appendix Figure 4 and attached Figure 6The connecting component 5 is used for the rapid assembly and connection of the heating pipe 1 and the heat dissipation component 2. The connecting component 5 includes an upper connecting part 52 and a lower connecting part 51 respectively placed on the upper and lower sides of the heating pipe 1. The lower connecting part 51 and the upper connecting part 52 are connected by bolts 57 and nuts 58. After the heating pipe 1 is placed between the lower connecting part 51 and the upper connecting part 52, the assembly between the heating pipe 1 and the lower connecting part 51 and the upper connecting part 52 can be realized by tightening the bolts 57 and nuts 58. The bottom of the lower connecting part 51 is equipped with a connector 53 that connects to the heat dissipation component 2 to realize the connection between the heating pipe 1 and the heat dissipation component 2. The connector 53 is inserted into the heat dissipation component 2 to realize the connection between the heating pipe 1 and the heat dissipation component 2, thereby ensuring the delivery of hot water. The heating pipe 1 includes a connecting pipe 11, a fitting 12, and a pipe hole 13. The pipe hole 13 is located on the outside of the connecting pipe 11 and is aligned with the middle channel of the lower connector 51. After the heating pipe 1 and the heat dissipation assembly 2 are connected by the connector 53, the upper connector 52, and the lower connector 51, the hot water entering through the connecting pipe 11 enters the heat dissipation assembly 2 through the pipe hole 13. The fitting 12 is sleeved on the end of the connecting pipe 11 and has threads on its inner wall. This threaded structure facilitates the connection of the connecting pipe 11 to the heating pipes inside the house. The heating pipe 1 also includes a rubber sealing ring 14, which is sleeved on the outside of the fitting 12. The fitting 12 is tightly fitted to the inner wall of the connecting pipe 11 through the rubber sealing ring 14. The outside of the fitting 12 has a groove that matches the rubber sealing ring 14 to ensure the stable installation of the rubber sealing ring 14. After the fitting 12 is inserted into the connecting pipe 11, the rubber sealing ring 14 is deformed by the compression of the connecting pipe 11 and the fitting 12, thereby achieving a sealed connection between the fitting 12 and the connecting pipe 11.

[0047] Please see the appendix Figure 1 - Appendix Figure 4 The heat dissipation component 2 includes a branch pipe 21 and a heat dissipation fin 22. The heat dissipation fin 22 is fixedly connected to the outer wall of the branch pipe 21. The branch pipe 21 is connected to the connecting pipe 11 to realize the transportation of hot water. The heat dissipation fin 22 is closely attached to the outer wall of the branch pipe 21. The branch pipe 21 is sleeved on the outside of the connector 53 and connected to the connecting pipe 11 through the connector 53 and the lower connector 51. The heat dissipation fin 22 is used to conduct the heat carried by the hot water inside the branch pipe 21 to the room, thereby realizing indoor heating.

[0048] Please see the appendix Figure 7 The heat sink 22 includes a heat-conducting part 221 that is tightly fitted to the branch pipe 21, multiple sets of heat dissipation parts 222 distributed around the heat-conducting part 221, and a protective part 223 connected to the heat-conducting part 221 and the heat dissipation parts 222. The heat-conducting part 221 and the heat dissipation parts 222 are used for heat introduction and heat dissipation, respectively, while the protective part 223 is used to shield and protect the front end of the heat sink.

[0049] The connecting component 5 also includes a mounting groove 54 and a gasket 56. The mounting groove 54 is located inside the lower connector 51. A second rubber sealing ring 55 is installed inside the mounting groove 54. The mounting groove 54 restricts the position of the second rubber sealing ring 55 to ensure the stability of the installation of the second rubber sealing ring 55. After the connecting pipe 11 is embedded inside the lower connector 51, the second rubber sealing ring 55 abuts against the outer bottom wall of the connecting pipe 11. When the connecting pipe 11 is installed between the lower connector 51 and the upper connector 52, under the continuous locking action of the bolt 57 and the nut 58, the connecting pipe 11 gradually squeezes the second rubber sealing ring 55 and causes the second rubber sealing ring 55 to deform. At this time, the second rubber sealing ring 55 is tightly attached to the outside of the lower connector 51 and the pipe hole 13, thereby achieving a tight connection between the connecting pipe 11 and the pipe fitting 12. The gasket 56 is sleeved on the outside of the connector 53 and provides protection.

[0050] Please see the appendix Figure 4 and attached Figure 6 The protective shell 3 is installed on the outside of the heating pipe 1 and the connecting assembly 5 to protect the connecting assembly 5. The protective shell 3 includes an outer shell 31 and a snap-fit ​​strip 32. The snap-fit ​​strip 32 is located inside the outer shell 31 and is integrally formed with the outer shell 31. The front side of the outer shell 31 is slightly higher than the rear side to ensure effective protection of the connecting assembly 5 structure and further improve the aesthetics of the radiator itself. The connecting assembly 5 also includes a stepped groove 1 59 and a stepped groove 2 510. Stepped groove 1 59 is located on the outside of the lower connector 51, and stepped groove 2 510 is located on the outside of the upper connector 52. After the protective shell 3 is fitted onto the outside of the connecting assembly 5, stepped groove 2 510 and stepped groove 1 59 are positioned between the two snap-fit ​​strips 32, forming a snap-fit ​​opening. When the protective shell 3 is inserted, the two snap-fit ​​strips 32 are engaged between the two openings, thereby ensuring the stability of the protective shell 3 installation.

[0051] Please see the appendix Figure 1 - Appendix Figure 3 The heating radiator also includes a side guard plate 4, which is placed outside the heating pipe 1 and snapped into the end of the protective shell 3. The side guard plate 4 has a notch in the middle for the heating pipe 1 to pass through. After installation, the side guard plate 4 is snapped into the end of the protective shell 3 to seal both sides of the protective shell 3 and provide a protection level.

[0052] A method for assembling a detachable, weld-free heating radiator includes the following steps:

[0053] The connecting component 5 is locked to the branch pipe 21 and the connecting pipe 11 using a rubber sealing ring 55, bolts 57, and nuts 58 to achieve sealing and fixation. During assembly, first, the nut 58 is inserted into the mounting hole at the bottom of the lower connecting component 51. Then, the gasket 56 is fitted onto the outside of the connector 53, and the connector 53 is inserted into the branch pipe 21 to achieve initial connection of the components. After that, the rubber sealing ring 55 is placed inside the mounting groove 54, and the pipe hole 13 at the bottom of the connecting pipe 11 is aligned with the channel inside the lower connecting component 51. Then, press down on the upper surface of the lower connector 51, and place the upper connector 52 corresponding to the lower connector 51 on the upper part of the connecting pipe 11, ensuring that the through holes around the upper connector 52 are aligned with the through holes around the lower connector 51. Then, insert the bolt 57 from the upper part of the upper connector 52, so that it passes through the through holes around the upper connector 52 and the lower connector 51 and is connected to the nut 58. Tighten the bolt 57 to lock the upper connector 52 and the lower connector 51, thereby completing the connection between the connecting pipe 11 and the branch pipe 21.

[0054] The protective shell 3 is then assembled onto the outside of the connecting component 5 via a snap-fit ​​structure, and cooperates with the pre-set side guard plate 4 to complete the protection of the component. The outer shell 31 is inserted from the side of the connecting component 5, so that the two protruding snap-fit ​​strips 32 on the inner side of the outer shell 31 are respectively placed at the bottom of the first step groove 59 and the top of the second step groove 510. The connection between the outer shell 31 and the connecting component 5 is achieved through the snap-fit ​​relationship between the first step groove 59 and the second step groove 510 and the snap-fit ​​strips 32, thereby protecting the entire component of the connecting component 5.

[0055] Finally, insert the two end fittings 12 into the connecting pipe 11 and connect them to the house heating system using the rubber sealing ring 14 to achieve a weld-free, detachable overall assembly. After assembling the radiator body, insert the fittings 12 into both ends of the connecting pipe 11, and connect the fittings 12 and the connecting pipe 11 using the rubber sealing ring 14 connected to the outside of the fittings 12. In this way, the radiator can be connected to the house heating pipeline through the fittings 12, completing the installation of the entire device.

[0056] Working principle: During assembly, first, insert the nut 58 into the mounting hole at the bottom of the lower connector 51. Then, fit the washer 56 onto the outside of the connector 53 and insert the connector 53 into the branch pipe 21 to achieve initial connection of the components. Next, place the rubber sealing ring 55 inside the mounting groove 54. Align the pipe hole 13 at the bottom of the connecting pipe 11 with the channel inside the lower connector 51 and press it onto the upper surface of the lower connector 51. Then, place the upper connector 52, corresponding to the lower connector 51, on the upper part of the connecting pipe 11 and ensure... Align the through holes around the upper connector 52 with the through holes around the lower connector 51. Then, insert the bolt 57 from the top of the upper connector 52, allowing it to pass through the through holes around both the upper and lower connectors 52 and connect with the nut 58. Tighten the bolt 57 to lock the upper connector 52 and lower connector 51, thus completing the connection between the connecting pipe 11 and the branch pipe 21. Then, connect the other branch pipes 21 to the connecting pipe 11 in the same manner to complete the assembly of the main pipeline. After this, the pipe... The fitting 12 is inserted into both ends of the connecting pipe 11. The connection between the fitting 12 and the connecting pipe 11 is completed through the rubber sealing ring 14 connected to the outside of the fitting 12. In this way, the radiator can be connected to the house heating pipe through the fitting 12, completing the installation of the entire equipment. Before this, the outer shell 31 is inserted from the side of the connecting assembly 5, so that the two protruding snap-fit ​​strips 32 on the inner side of the outer shell 31 are respectively placed at the bottom of the first step groove 59 and the top of the second step groove 510. The snap-fit ​​strips 32 are connected to the first step groove 59 and the second step groove 510 through the snap-fit ​​strips 32. The snap-fit ​​relationship of 2 is used to connect the outer shell 31 and the connecting component 5, thereby protecting the entire component of the connecting component 5. After the outer shell 31 is installed, the side guard plate 4, which is pre-fitted onto the heating pipe of the house, is snapped into the outer shell 31 to protect the side of the outer shell 31, thereby further improving the protection level of the connecting component 5. The above is the entire installation process of the equipment. When a component is damaged, it can be disassembled by a single person to facilitate the repair and maintenance of the radiator, greatly reducing maintenance costs.

[0057] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
