[0002] A heating coil is a piping device used to transfer heat energy and achieve heating function. It is usually made of metal tubes wound into a specific shape, with hot water, steam or heat transfer oil flowing inside. It exchanges heat with the surrounding medium through the tube wall, thereby transferring heat to the object being heated. It is widely used in heating processes in industrial production, air heating in HVAC systems, and heating and hot water supply in civil fields. It has the advantages of high heating efficiency, compact structure and flexible installation.

[0003] Existing patent CN218106759U discloses a steam heating coil assembly, including a housing, with a pair of support seats arranged below the housing and the housing communicating with the support seats. A heating coil is arranged inside the housing, and flanges are respectively provided at both ends of the heating coil. Quick-connect interfaces are provided on the flanges, with one quick-connect interface being a steam inlet and the other being a steam outlet. This prior art has a simple structure, is easy to disassemble and clean, and is small in size, lightweight, and highly efficient.

[0004] However, in the aforementioned existing technologies, since the cabinet is integrally molded and the heating coil is installed inside the cabinet, if the heating coil malfunctions, it can only be disassembled by breaking part of the cabinet structure, resulting in high maintenance costs. Utility Model Content

[0005] The purpose of this utility model is to provide a steam heating coil assembly that is easy to maintain. The housing is composed of a detachable upper panel and a lower panel. When the heating coil malfunctions, the detachable fasteners can separate the upper panel and the lower panel, and then the heating coil can be taken out for maintenance without damaging the housing structure, which effectively reduces maintenance costs and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A steam heating coil assembly for easy maintenance includes an upper panel, a lower panel, and a heating coil. Several upper fixing blocks are connected to the edge of the upper panel, and a lower fixing block is connected to the edge of the lower panel. Fasteners are connected to the upper and lower fixing blocks so that the upper and lower panels enclose a sealed enclosure. The heating coil is housed between the upper and lower panels, and its two ends are a steam inlet and a steam outlet, respectively. Both the steam inlet and the steam outlet are connected to quick-connect interfaces, and the two quick-connect interfaces extend to the outside of the enclosure.

[0007] A further improvement of this utility model is that the upper fixing block and the lower fixing block are vertically aligned, and both the upper fixing block and the lower fixing block are provided with fixing holes; the fastener is a bolt and nut assembly, which fixes the upper fixing block and the lower fixing block through the fixing holes.

[0008] A further improvement of this utility model is that a protruding strip is connected to the open end face of the upper box plate, and a groove is provided on the open end face of the lower box plate. A sealing strip is placed in the groove, and the protruding strip is inserted into the groove and abuts against the sealing strip.

[0009] A further improvement of this invention is that the material of the sealing strip includes, but is not limited to, EPDM rubber or silicone rubber, with silicone rubber being preferred as it is more heat-resistant.

[0010] A further improvement of this utility model is that the heating coil inside the box is a serpentine coil or a spiral coil, and the cross-section of the heating coil is circular.

[0011] A further improvement of this utility model is that a clamping component is connected inside the box, and the heating coil is connected to the clamping component.

[0012] A further improvement of this utility model is that the clamping member includes an upper clamping frame and a lower clamping frame. The upper clamping frame is connected to the top wall of the upper box plate, and the lower clamping frame is connected to the bottom wall of the lower box plate. Both the upper clamping frame and the lower clamping frame abut against the heating coil.

[0013] A further improvement of this utility model is that the opposing ends of the upper clamping frame and the lower clamping frame are arc-shaped and connected with a buffer pad. The buffer pad abuts against the outer wall of the heating coil. The material of the buffer pad is preferably high-temperature resistant silicone rubber.

[0014] The beneficial effects of this utility model are: This utility model provides a convenient steam heating coil assembly. The housing is composed of a detachable upper and lower panel. When the heating coil malfunctions, the detachable fasteners can separate the upper and lower panels, and then the heating coil can be removed for repair without damaging the housing structure, effectively reducing maintenance costs.

[0015] This utility model provides a convenient steam heating coil assembly. The sealing structure effectively enhances the sealing performance after the upper and lower boxes are closed, preventing steam from leaking from the box connection during the heating process. This avoids steam waste and reduces energy consumption, while also preventing leaked steam from causing adverse effects on the surrounding environment and equipment.

[0016] This utility model provides a convenient steam heating coil assembly. The clamping component provides stable support for the heating coil, ensuring that the heating coil is fixed in position within the housing and will not shake or shift due to steam flow or other external forces. This guarantees the stability of the contact between the heating coil and the steam, thereby maintaining a stable heating effect. At the same time, the reasonable clamping design also facilitates the installation and removal of the heating coil, allowing for quick operation when maintenance or replacement is needed, thus improving maintenance efficiency.

[0017] This utility model provides a convenient steam heating coil assembly. During equipment operation, the buffer pad can play a shock absorption role, reducing the impact of steam flow or equipment vibration on the heating coil, further extending the service life of the heating coil, reducing the probability of equipment failure, and improving the operational stability and reliability of the entire steam heating coil assembly.

Detailed Implementation

[0026] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1: As Figures 1-7As shown, a steam heating coil assembly that is easy to maintain includes an upper box plate 1, a lower box plate 2, and a heating coil 3. Several upper fixing blocks 4 are connected to the edge of the upper box plate 1, and lower fixing blocks 5 are connected to the edge of the lower box plate 2. Fasteners are connected to the upper fixing blocks 4 and the lower fixing blocks 5 so that the upper box plate 1 and the lower box plate 2 enclose a sealed box. The heating coil 3 is housed between the upper box plate 1 and the lower box plate 2. The two ends of the heating coil 3 are a steam inlet and a steam outlet, respectively. Quick connectors 6 are connected to both the steam inlet and the steam outlet, and the two quick connectors 6 extend to the outside of the box.

[0028] The upper fixing block 4 and the lower fixing block 5 are vertically aligned, and both the upper fixing block 4 and the lower fixing block 5 are provided with fixing holes; the fastener is a bolt and nut assembly 7, which fixes the upper fixing block 4 and the lower fixing block 5 through the fixing holes.

[0029] In this embodiment, the combined design of the upper box plate 1, lower box plate 2, heating coil 3, and multiple bolt and nut assemblies 7 provides a stable and effective structural foundation for steam heating. The upper box plate 1 covers the lower box plate 2 directly above it, and a stable connection is achieved through multiple components set between corresponding upper fixing blocks 4 and lower fixing blocks 5. Compared with a one-piece molded box, this split design eliminates the need to damage the box structure when the heating coil 3 malfunctions. Only the bolt and nut assemblies 7 need to be disassembled to separate the box, greatly reducing maintenance costs. At the same time, the quick-connect interfaces 6 set at both ends of the heating coil 3 facilitate the access and discharge of steam, improving the overall ease of use and efficiency.

[0030] In this embodiment, one of the quick interfaces 6 is set as a steam inlet and the other as a steam outlet. This facilitates the circulation of steam along a predetermined path, ensuring that the steam can fully exchange heat with the surrounding environment, improving the efficiency and effect of steam heating, avoiding uneven heating caused by chaotic steam flow, and making the working performance of the entire steam heating coil 3 assembly more stable and reliable.

[0031] A protruding strip 8 is connected to the open end face of the upper box plate 1, and a groove 9 is provided on the open end face of the lower box plate 2. A sealing strip 10 is placed in the groove 9. The protruding strip 8 is inserted into the groove 9 and abuts against the sealing strip 10. The sealing strip 10 is made of silicone rubber.

[0032] In this embodiment, this design effectively enhances the sealing performance of the upper box plate 1 and the lower box plate 2 after they are closed; it can prevent steam from leaking from the box connection during the heating process, thus avoiding steam waste and reducing energy consumption; on the other hand, it prevents leaked steam from causing adverse effects on the surrounding environment and equipment.

[0033] The heating coil 3 inside the box is a serpentine coil, and the cross-section of the heating coil 3 is circular.

[0034] Example 2: This example is a further improvement on Example 1. The main improvement is that, in Example 1, the heating coil 3 would shake or shift due to steam flow or other external forces during use; however, in this example, the above-mentioned defects can be avoided. Specifically: A clamping device is connected inside the housing, and the heating coil 3 is connected to the clamping device. The clamping device includes an upper clamping frame 11 and a lower clamping frame 12. The upper clamping frame 11 is connected to the top wall of the upper housing plate 1, and the lower clamping frame 12 is connected to the bottom wall of the lower housing plate 2. Both the upper clamping frame 11 and the lower clamping frame 12 abut against the heating coil 3. The opposing ends of the upper clamping frame 11 and the lower clamping frame 12 are arc-shaped and connected to a buffer pad 13. The buffer pad 13 abuts against the outer wall of the heating coil 3. The material of the buffer pad 13 is preferably high-temperature resistant silicone rubber. In this embodiment, the clamping device provides a stable support for the heating coil 3, ensuring that the heating coil 3 is fixed in position inside the housing and will not be affected by external forces. The swaying or displacement caused by steam flow or other external forces ensures the stability of the contact between the heating coil 3 and the steam, thereby maintaining a stable heating effect. At the same time, the reasonable clamping design facilitates the installation and disassembly of the heating coil 3, enabling quick operation when maintenance or replacement is required, thus improving maintenance efficiency. In addition, during equipment operation, the buffer pad 13 can play a shock absorption role, reducing the impact of the impact force generated by steam flow or equipment vibration on the heating coil 3, further extending the service life of the heating coil 3, reducing the probability of equipment failure, and improving the operational stability and reliability of the entire steam heating coil 3 assembly.

[0035] Apart from the above, this embodiment is exactly the same as Embodiment 1, and will not be described again here.

[0036] The specific principle of this utility model is as follows: During assembly, the lower box plate 2 is placed stably in a suitable position, and the heating coil 3 is initially fixed to the bottom wall of the lower box plate 2 by the lower clamping bracket 12 of the clamping component to ensure accurate and stable positioning. Then, the upper box plate 1 is aligned and covered directly above the lower box plate 2, so that the protrusion 8 on the outer edge of the upper box plate 1 abuts against the sealing strip 10 in the groove 9 on the outer edge of the lower box plate 2 to ensure good sealing. Subsequently, multiple bolt and nut assemblies 7 are installed between the corresponding upper fixing block 4 and lower fixing block 5 to complete the firm connection between the upper box plate 1 and the lower box plate 2.

[0037] During operation, the steam source is connected to one of the quick-connect interfaces 6 set as the steam inlet, and the other quick-connect interface 6 set as the steam outlet is connected to the steam recovery or utilization system. During operation, the upper clamping frame 11 and the lower clamping frame 12 work together to provide stable support for the heating coil 3, and the buffer pad 13 at the point where the two clamping frames meet the heating coil 3 can reduce compression and vibration. When the heating coil 3 malfunctions and needs to be repaired, simply disassemble the bolt and nut assembly 7, separate the upper box plate 1 and the lower box plate 2, and then use the clamping components to remove the heating coil 3 for inspection or replacement.

[0038] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent transformations or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
