Description

Technical Field

[0001] The utility model relates to the technical field of air - energy coils, and specifically, to an air - energy coil assembly. Background Art

[0002] In the field of air - energy technology, the coil assembly is a crucial part, and its performance directly affects the efficiency and stability of the entire system. Traditional air - energy coil assemblies usually adopt a welding method for hard connection. Although this connection is firm, there are some problems in the actual operation process.

[0003] Especially when the pipe wall is relatively thin (for example, 0.7 mm), in order to ensure excellent heat transfer capacity, it is very easy to cause excessive welding during the welding process. This excessive welding not only affects the strength of the connection between the coil and the base, but also may cause rust or perforation at this place during the later use process. Once a perforation occurs, the coil will be filled with water, which may lead to the scrapping of the whole machine, seriously affecting the service life and reliability of the equipment. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an air - energy coil assembly to solve the problems that the excessive welding not only affects the strength of the connection between the coil and the base, but also may cause rust or perforation at this place during the later use process as mentioned in the above background art.

[0005] To achieve the above purpose, the utility model provides an air - energy coil assembly, including a housing. A fixing plate is installed on the top of the housing. Two connecting components are installed on the fixing plate. The top end of the connecting component is connected to a single pipe. The bottom end of the single pipe passes through the housing and is helically wound with each other to form a coil. The connecting component includes a base. A channel is arranged in the middle of the base. The single pipe passes through the channel. A nut sleeve is installed on the outer side of the top of the base. A rubber ring is installed at the top opening of the channel of the base.

[0006] Preferably, the cross - section of the rubber ring is a triangular structure, and the inner circle fits on the outer wall of the single pipe.

[0007] Preferably, the outer side wall of the rubber ring is an inclined surface, which is in butt - joint fit with the top opening of the base.

[0008] Preferably, the top of the rubber ring is a horizontal plane, and the inner side of the top of the nut sleeve abuts on the horizontal plane at the top of the rubber ring.

[0009] Preferably, a non - slip ring is installed at the top opening of the channel of the base. The inner side of the non - slip ring fits with the rubber ring, and the outer side of the non - slip ring is bonded to the base.

[0010] Preferably, the outer wall of the base is provided with external threads, and the inner wall of the nut sleeve is provided with internal threads.

[0011] Preferably, the diameter of the internal passage of the base is larger than the outer wall diameter of the single pipe.

[0012] Preferably, the outer wall of the nut sleeve is of a circular structure or a hexagonal structure.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] In this air energy coil assembly, through innovative design, the stability and service life of the system are significantly improved. Especially in the design of the connection assembly, a soft connection method of rubber ring extrusion is adopted, replacing the traditional welded hard connection. This method not only avoids problems such as over-welding, rust, and perforation that may occur during the welding process, but also enhances the firmness and reliability of the connection through the sealing and fixing effects of the rubber ring. At the same time, the threaded connection design between the base and the nut sleeve makes the installation and disassembly processes more convenient and rapid, greatly improving the maintenance efficiency. In addition, the setting of the anti-slip ring further enhances the friction between the rubber ring and the base, preventing the rubber ring from sliding or falling off during use. In summary, the air energy coil assembly of the present utility model has achieved significant improvements in technology, providing a strong guarantee for the efficient and stable operation of the air energy system.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model provides an air - energy coil assembly, as Figures 1 - 3 shown, which includes a housing 1. A fixing plate 2 is installed at the top of the housing 1. Two connecting components 5 are installed on the fixing plate 2. The top ends of the connecting components 5, which facilitate the fixed connection between the single pipe 3 and the housing 1, are connected to the single pipe 3. The bottom ends of the single pipes 3 pass through the housing 1 and are helically wound with each other to form a coil 4. The connecting component 5 includes a base 52. A bottom plate 53 is installed at the bottom of the base 52. A channel is provided in the middle of the base 52. The single pipe 3 passes through the channel. A nut sleeve 51 is installed on the outer side of the top of the base 52. A rubber ring 54 is installed at the top opening of the channel of the base 52, which plays a good role in extruding and fixing the single pipe 3.

[0022] In this embodiment, the cross - section of the rubber ring 54 is a triangular structure, and the inner ring fits on the outer wall of the single pipe 3 to ensure the pressing and positioning of the outer wall of the single pipe 3 by the rubber ring 54.

[0023] Specifically, the outer side wall of the rubber ring 54 is an inclined surface, which is in butt - joint cooperation with the top opening of the base 52 to ensure the support and positioning of the rubber ring 54 by the base 52.

[0024] Furthermore, the top of the rubber ring 54 is a horizontal plane, and the inner side of the top of the nut sleeve 51 abuts against the top horizontal plane of the rubber ring 54. A downward acting force is applied to the rubber ring 54 through the nut sleeve 51, thereby realizing the fixation of the rubber ring 54.

[0025] Furthermore, a non - slip ring 522 is installed at the top opening of the channel of the base 52. The inner side of the non - slip ring 522 fits with the rubber ring 54, and the outer side of the non - slip ring 522 is bonded to the base 52, which plays a non - slip operation on the rubber ring 54 to avoid the sliding and deviation of the rubber ring 54.

[0026] Furthermore, an external thread 521 is provided on the outer wall of the base 52, and an internal thread 511 is provided on the inner wall of the nut sleeve 51. The nut sleeve 51 is screwed and pressed on the base 52 to further squeeze the rubber ring 54, thereby pressing and fixing the single pipe 3.

[0027] Furthermore, the diameter of the internal channel of the base 52 is larger than the outer diameter of the single pipe 3 to facilitate the flexible passing of the single pipe 3.

[0028] Furthermore, the outer wall of the nut sleeve 51 is a circular structure or a hexagonal structure, which is convenient for manual or tool screwing operation.

[0029] When the air - energy coil assembly of the present utility model is in use, first, the single pipe 3 is passed through the channel in the middle of the base 52 to ensure that the single pipe can fit flexibly and tightly in the channel. Subsequently, the rubber ring 54 is installed at the top opening of the channel of the base 52. The triangular cross - section design of the rubber ring enables it to fit tightly on the outer wall of the single pipe 3, providing a preliminary pressing and positioning effect.

[0030] To further fix the single tube 3, a nut sleeve 51 is installed on the outer side of the top of the base 52. The nut sleeve 51 is threadedly connected to the base 52. When the nut sleeve 51 is screwed downwards, the inner side of its top will abut against the top horizontal plane of the rubber ring 54, exerting a downward force on the rubber ring. During this process, the rubber ring 54 is squeezed, and the outer inclined surface fits tightly with the top opening of the base 52. At the same time, the anti-slip ring 522 enhances the friction between the rubber ring and the base, preventing the rubber ring from sliding.

[0031] As the nut sleeve 51 is continuously tightened, the pressing force of the rubber ring 54 on the single tube 3 gradually increases, thus achieving a firm fixation of the single tube. This connection method not only avoids problems that may be brought about by traditional welding methods, such as over-welding, rusting, and perforation, but also provides a more flexible and reliable connection method, ensuring the long-term stable operation of the air energy coil assembly.

[0032] The above shows and describes the basic principles, main features, and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
