Description

Technical Field

[0001] This utility model relates to the field of heating tube technology, and in particular to a spiral high-efficiency energy-saving heating tube. Background Technology

[0002] A spiral heating element is a tubular electric heating element with a spiral coil as its core structure. Its main frame consists of a hollow tube, inlet / outlet water connectors, and flow guiding components. It is widely used in showers, industrial heating equipment, and other applications requiring uniform heating and scale prevention.

[0003] Existing spiral high-efficiency energy-saving heating tubes mostly rely on simple fixation at both ends, lacking effective support in the middle section. This leads to stress concentration due to thermal expansion and contraction under long-term high-temperature operation or media impact. Furthermore, the unique spiral structure of the spiral heating tube easily forms turbulence, resulting in insufficient heat exchange. Summary of the Invention

[0004] Based on this, it is necessary to address the aforementioned technical problems. Spiral heating tubes often rely on simple fixation at both ends, lacking effective support in the middle section. This leads to stress concentration due to thermal expansion and contraction under long-term high-temperature operation or media impact. Furthermore, the unique spiral structure of spiral heating tubes easily generates turbulence, resulting in insufficient heat exchange.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A spiral high-efficiency energy-saving heating tube includes a spiral heating tube with a stabilizing mechanism inside. The stabilizing mechanism includes positioning rings and connecting components. Two positioning rings are provided and installed at both ends of the spiral heating tube, respectively, and the two positioning rings are symmetrical. The connecting component includes a rotating disk with arc-shaped frames at both ends of the rotating disk. The arc-shaped frames cooperate with the positioning rings. Multiple flow guiding mechanisms are uniformly arranged on the surface of the spiral heating tube.

[0006] In a preferred embodiment of the spiral high-efficiency energy-saving heating tube provided by this utility model, a protruding block is fixedly installed at one end of the two positioning rings that are far apart from each other. The surface of the arc frame is in contact with the surface of the positioning ring. A positioning plate is provided at the end of the arc frame. The positioning plate is close to the surface of the protruding block. The positioning plate and the protruding block are fixedly connected by bolts.

[0007] In a preferred embodiment of the spiral high-efficiency energy-saving heating tube provided by this utility model, a light rod is fixedly installed directly below the rotating disk, and a plurality of protruding columns are arranged on the surface of the light rod.

[0008] In a preferred embodiment of the spiral high-efficiency energy-saving heating tube provided by this utility model, a protective sleeve is fitted onto the end of the protruding column.

[0009] As a preferred embodiment of the spiral high-efficiency energy-saving heating tube provided by this utility model, the flow guiding mechanism includes a flow guiding block and a pressure groove. The flow guiding block is disposed on the inner wall of the spiral heating tube, the surface of the flow guiding block is set as a smooth arc surface, and the shape of the flow guiding block is set as an arc. The flow guiding block and the pressure groove are disposed on the outer surface of the spiral heating tube, and the pressure groove corresponds to the flow guiding block.

[0010] In a preferred embodiment of the spiral high-efficiency energy-saving heating tube provided by this utility model, the surface of the spiral heating tube is fitted with an outer cover.

[0011] In a preferred embodiment of the spiral high-efficiency energy-saving heating tube provided by this utility model, both the protective sleeve and the outer cover are made of silicone material.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The two ends are connected by bolts through positioning rings, protrusions, arc-shaped frames and positioning plates to form a ring-shaped fixation, which can effectively maintain the end shape of the spiral heating tube and buffer the stress of thermal expansion and contraction. The middle section uses the precise matching of the thread pitch of the spiral heating tube with the smooth rod and the protruding column to form multiple constraints, avoiding deformation or sagging of the spiral structure due to its large span, and achieving full-section stability with fixed ends and middle support. The flow guide block can guide the orderly flow of fluid, reducing the disorderly impact between the fluid and the pipe wall and the turbulent noise. At the same time, the stable flow state reduces the periodic impact force of the fluid on the pipe wall, reduces the vibration of the spiral heating tube, and improves the stability and quietness of the equipment operation. In addition, the flow guide block increases the contact area between the spiral heating tube and the fluid, accelerating heat transfer. The groove on the outer wall creates a concave-convex structure on the outer surface of the spiral heating tube, expanding the contact area with the external heat source and accelerating the transfer of heat from the outside to the pipe wall, and then through the pipe wall to the internal fluid, thus improving the overall heat transfer speed.

[0016] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0017] As described in the background section, spiral heating tubes often rely on simple fixation at both ends, with a lack of effective support in the middle section. This leads to stress concentration due to thermal expansion and contraction under long-term high-temperature operation or media impact. Furthermore, the unique spiral structure of spiral heating tubes easily generates turbulence, resulting in insufficient heat exchange.

[0018] To solve this technical problem, this utility model provides a spiral high-efficiency energy-saving heating tube, which includes a spiral heating tube 1. The spiral heating tube 1 is provided with a stabilizing mechanism, which includes a positioning ring 2 and a connecting component 13. There are two positioning rings 2, which are respectively installed at both ends of the spiral heating tube 1 and are symmetrical. The connecting component 13 includes a rotating disk 4, and arc-shaped frames 5 are provided at both ends of the rotating disk 4. The arc-shaped frames 5 cooperate with the positioning rings 2. Multiple flow guiding mechanisms are evenly provided on the surface of the spiral heating tube 1. By setting a stabilizing mechanism on the surface of the spiral heating tube 1, multiple constraints can be formed on the spiral heating tube 1, achieving full-section stability with both ends fixed and the middle supported; By setting a flow guiding mechanism on the surface of the spiral heating tube 1, the fluid can be guided to flow in an orderly manner, reducing the disorderly impact between the fluid and the tube wall and the turbulent noise, reducing the vibration of the spiral heating tube 1, improving the stability and quietness of the equipment operation, and also improving the overall heat transfer speed.

[0019] Example 1

[0020] Please refer to Figure 1 , 2 : Two positioning rings 2 are fixedly installed with protruding blocks 3 at their far ends. The surface of the arc frame 5 matches the surface of the positioning rings 2. A positioning plate 6 is provided at the end of the arc frame 5. The positioning plate 6 is close to the surface of the protruding block 3. The positioning plate 6 and the protruding block 3 are fixedly connected by bolts. The surface of the arc-shaped frame 5 is in contact with the surface of the positioning ring 2, and its curved design matches the curvature of the positioning ring 2, ensuring a tight contact between the connecting component 13 and the positioning ring 2, forming a ring-shaped support structure to reinforce the shape of the spiral heating tube 1. The positioning plate 6 at the end of the arc-shaped frame 5 is close to the surface of the protrusion 3, and the two are rigidly connected by bolts. The bolt connection not only ensures a tight fit between the positioning plate 6 and the protrusion 3, but also provides an adjustable preload, making the fit between the arc-shaped frame 5 and the positioning ring 2 more stable. At the same time, it allows for disassembly and adjustment during installation or maintenance. Through the cooperation of the positioning ring 2 and the connecting component 13, the stability between the two ends of the spiral heating tube 1 can be significantly enhanced, ensuring the stability of the spiral heating tube 1 during the trial period.

[0021] A light rod 7 is fixedly installed directly below the rotating disk 4. Multiple protruding posts 8 are arranged on the surface of the light rod 7. The light rod 7 can be engaged in the thread pitch of the spiral heating tube 1 by rotation. Multiple protruding posts 8 are arranged along the length of the smooth rod 7, and the size and spacing of the protruding posts 8 match the thread pitch of the spiral heating tube 1. When the smooth rod 7 rotates with the rotating disk 4, the protruding posts 8 can be precisely engaged in the thread pitch of the spiral heating tube 1 to form support for the spiral structure in the middle section. Each protruding post 8 is embedded in a corresponding thread gap, and the spiral tube is constrained by mechanical clamping to ensure the stability of the spiral part of the spiral heating tube 1.

[0022] Example 2

[0023] Further optimizations to Example 1, specifically, such as... Figure 3-5 As shown: The flow guiding mechanism includes a flow guiding block 11 and a pressure groove 12. The flow guiding block 11 is disposed on the inner wall of the spiral heating tube 1. The surface of the flow guiding block 11 is a smooth arc surface. The shape of the flow guiding block 11 is arc-shaped. The flow guiding block 11 and the pressure groove 12 are disposed on the outer surface of the spiral heating tube 1. The pressure groove 12 corresponds to the flow guiding block 11. The guide block 11 is arc-shaped and has a smooth surface, protruding from the inner wall of the spiral heating tube 1. Its shape is adapted to the spiral path of the spiral heating tube 1. The guide block 11 guides the fluid to flow in an orderly manner, reducing the disorderly impact of the fluid on the tube wall and the turbulent noise. At the same time, the stable flow state reduces the periodic impact force of the fluid on the tube wall. Furthermore, the guide block 11 increases the contact area between the inside of the spiral heating tube 1 and the fluid, accelerating heat transfer. The pressure groove 12 on the outer wall forms a concave-convex structure on the outer surface of the spiral heating tube 1, expanding the contact area with the external heat source.

[0024] Example 3

[0025] Further optimizations to Examples 1 and 2, such as Figure 1-3 As shown: A protective sleeve 9 is fitted onto the end of the protruding post 8; After the protective sleeve 9 is fitted onto the end of the protruding post 8, when the protruding post 8 contacts the thread gap of the spiral heating tube 1, it avoids the protruding post 8 directly contacting the surface of the spiral heating tube 1, thus avoiding rigid collision or friction between the two.

[0026] The surface of the spiral heating tube 1 is fitted with an outer cover 10; The outer cover 10 reduces wear, corrosion, or scaling on the surface of the spiral heating tube 1 by isolating it from external impurities, corrosive substances, and mechanical impacts.

[0027] Both the protective case 9 and the outer cover 10 are made of silicone material; Silicone is resistant to aging, high and low temperatures, and chemical corrosion. It can maintain stable performance in the long-term high-temperature working environment of the spiral heating tube 1, greatly extending the service life of the protective sleeve 9 and the outer cover 10 and reducing the replacement frequency.

[0028] The application process of the spiral high-efficiency energy-saving heating tube provided by this utility model is as follows: First, the spiral heating tube 1 is fixed by a stabilizing mechanism. Two positioning rings 2 are fixedly installed at both ends of the spiral heating tube 1. The arc-shaped frame 5 of the connecting assembly 13 is used to fit the curved surface of the positioning ring 2, so that the positioning plate 6 at the end of the arc-shaped frame 5 is close to the protrusion 3 on the positioning ring 2. Then, it is rigidly connected by bolts to form a ring-shaped support, which strengthens the overall shape of the spiral heating tube 1. The light rod 7 below it will rotate with the rotating disk 4. When the arc-shaped frame 5 fits the curved surface of the positioning ring 2, the protrusion 8 on the surface of the light rod 7 can be accurately engaged in the thread pitch of the spiral heating tube 1, thus strengthening the spiral structure. The middle section forms a mechanical constraint, further enhancing the stability of the spiral heating tube 1 and preventing structural deformation caused by vibration during operation. The fluid to be heated enters the interior of the spiral heating tube 1, while the external heat source acts on the outer surface of the spiral heating tube 1. When the fluid flows inside the tube, it is guided by the arc-shaped guide block 11 on the inner wall. The smooth arc surface of the guide block 11 is adapted to the spiral path of the spiral heating tube 1, so that the fluid flows along an orderly path, reducing disordered impact and turbulence, and reducing flow noise. At the same time, the guide block 11 increases the contact area between the inside of the tube and the fluid, accelerating the transfer of heat from the tube wall to the internal fluid.
