Description

Technical Field

[0001] The utility model relates to a heating tube with fins, belonging to the technical field of heating tube equipment. Background Technique

[0002] An electric heating tube is a tubular electric heating element, which is composed of a metal tube, a spiral resistance wire, crystalline magnesium oxide powder, etc. Electric heating tube products generally use high-quality imported stainless steel tubes, imported high-temperature magnesium oxide powder, high-quality electric heating wires and other materials to make heating elements, and use stainless steel to make other structural parts, with excellent overall performance, long service life and easy maintenance. In the prior art, in order to accelerate the diffusion of heat, heat dissipation fins are often sleeved on the tube body of the heating tube. In order to fix the heat dissipation fins, welding is usually used.

[0003] Publication No.: CN217721516U mentions a heating tube with fins. In the initial state of the device, the clips on the heat dissipation fins expand outwards, which is convenient for sleeving the heat dissipation fins on the vertical tube of the U-shaped tube through the jacks. Then, the clips are clamped as a whole with tools, so that the clips are attached to and finally pressed against the vertical tube. In this way, the heat dissipation fins are clamped and fixed to the vertical tube through the clips, and then the remaining heat dissipation fins are sleeved in this way; since the heat dissipation fins are purely physically pressed by the clips and no welding is required, the heat dissipation fins can be directly pressed and fixed to the heating tube, and it is difficult to be oxidized at high temperature when being in water for a long time and is not easy to fall off. However, after the heat dissipation fins are physically pressed by the clips in this device, it is inconvenient to disassemble them from the heating tube. Once damaged, the whole needs to be replaced, which is rather inconvenient. Now there is an urgent need for a heating tube with fins to solve the above problems. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a heating tube with fins to solve the problems put forward in the above background technique. The utility model designs a detachable protective fin heating tube structure, which can realize the rapid disassembly between the heating tube and each fin, and at the same time does not affect its heat conduction effect.

[0005] To achieve the above object, the present utility model is realized through the following technical solutions: A finned heating tube, comprising a heating tube main body, a heat conducting cylinder, an arc-shaped bent tube, a first internal thread block and a second internal thread block. External screw grooves are engraved on both the left and right sides of the heating tube main body. There are two heat conducting cylinders. A first ceramic external screw tube and a second ceramic external screw tube are longitudinally fixed at the upper ends of the two heat conducting cylinders respectively. An arc-shaped opening groove is formed at the front end of the arc-shaped bent tube. A first U-shaped clamping block and a second U-shaped clamping block are symmetrically fixed at the left and right ends inside the arc-shaped opening groove. The arc-shaped section of the heating tube main body is clamped into the arc-shaped bent tube through the arc-shaped opening groove. The left and right ends of the heating tube main body respectively pass through the two heat conducting cylinders, the first ceramic external screw tube and the second ceramic external screw tube. The first internal thread block and the second internal thread block pass through the left and right sides of the upper end of the heating tube main body.

[0006] Furthermore, a plurality of heat dissipation fins are arranged on the outside of the two heat conducting cylinders, and a plurality of auxiliary fins are arranged at the rear side of the arc-shaped bent tube.

[0007] Furthermore, the arc-shaped bent tube is in contact with the lower ends of the two heat conducting cylinders.

[0008] Furthermore, honeycomb holes are formed on the outside of the two heat conducting cylinders and the outside of the arc-shaped bent tube.

[0009] Furthermore, the first internal thread block is screwed onto the outside of the first ceramic external screw tube and the left external screw groove by the thread principle.

[0010] Furthermore, the second internal thread block is screwed onto the outside of the second ceramic external screw tube and the right external screw groove by the thread principle.

[0011] The beneficial effects of the present utility model: For a finned heating tube of the present utility model, due to the addition of a heat conducting cylinder, a first ceramic external screw tube, a first internal thread block, an arc-shaped bent tube, an arc-shaped opening groove, auxiliary fins, a first U-shaped clamping block, a second ceramic external screw tube, a second internal thread block, a second U-shaped clamping block and an external screw groove in the present utility model, through our design improvement and actual use, it shows that the structure of this device is reasonable, has good practicability, and designs a detachable protective fin heating tube structure, which can realize the rapid disassembly between the heating tube and each fin, and at the same time does not affect its heat conduction effect.

Specific embodiments

[0018] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please refer to Figures 1-4 , the present utility model provides a technical solution: a finned heating tube, including a heating tube body 1, a heat conduction cylinder 2, an arc-shaped bent tube 6, a first internal thread block 5 and a second internal thread block 11. External screw grooves 13 are engraved on both the left and right sides of the heating tube body 1. There are two heat conduction cylinders 2, and a first ceramic external screw tube 4 and a second ceramic external screw tube 10 are longitudinally fixed at the upper ends of the two heat conduction cylinders 2 respectively. An arc-shaped opening groove 7 is opened at the front end of the arc-shaped bent tube 6, and a first U-shaped clamping block 9 and a second U-shaped clamping block 12 are symmetrically fixed at the left and right ends inside the arc-shaped opening groove 7. The arc-shaped section of the heating tube body 1 is clamped into the arc-shaped bent tube 6 through the arc-shaped opening groove 7. The left and right ends of the heating tube body 1 respectively pass through the two heat conduction cylinders 2, the first ceramic external screw tube 4 and the second ceramic external screw tube 10. The first internal thread block 5 and the second internal thread block 11 pass through the left and right sides of the upper end of the heating tube body 1. This design solves the problem that in the original device, after the heat dissipation fins are physically pressed by the clip pieces, it is inconvenient to disassemble them from the heating tube. Once damaged, the whole needs to be replaced, which is rather inconvenient.

[0020] As the first embodiment of the present utility model: A plurality of heat dissipation fins 3 are arranged on the outside of the two heat conduction cylinders 2, and a plurality of auxiliary fins 8 are arranged at the rear side of the arc-shaped bent tube 6. The addition of the plurality of auxiliary fins 8 at the rear side of the arc-shaped bent tube 6 does not affect the opening and use of the arc-shaped opening groove 7. The arc-shaped bent tube 6 is attached to the lower ends of the two heat conduction cylinders 2, and the added arc-shaped bent tube 6 and the two heat conduction cylinders 2 together can protect the heating tube body 1.

[0021] Honeycomb holes are provided on the outer parts of both of the two heat conducting cylinders 2 and the outer part of the arc-shaped elbow 6. By adding the honeycomb holes, the overall weight of the two heat conducting cylinders 2 and the arc-shaped elbow 6 can be reduced without affecting the heat dissipation and heat conduction of the heating tube main body 1.

[0022] The first internal thread block 5 is screwed onto the outer parts of the first ceramic external thread tube 4 and the left external thread groove 13 by the thread principle. By adding the first internal thread block 5 which is screwed onto the outer parts of the first ceramic external thread tube 4 and the left external thread groove 13 by the thread principle, the screwing and fixing on the left side of the upper end of the heating tube main body 1 is thus ensured. The second internal thread block 11 is screwed onto the outer parts of the second ceramic external thread tube 10 and the right external thread groove 13 by the thread principle. By adding the second internal thread block 11 which is screwed onto the outer parts of the second ceramic external thread tube 10 and the right external thread groove 13 by the thread principle, the screwing and fixing on the right side of the upper end of the heating tube main body 1 is thus ensured, and the installation of the heating tube main body 1 becomes more convenient.

[0023] As the second embodiment of the present utility model: When the heating tube main body 1 needs to be installed and used, first, the arc-shaped section of the heating tube main body 1 is snapped into the arc-shaped elbow 6 through the arc-shaped opening groove 7, so that the left and right ends of the heating tube main body 1 are respectively snapped into the first U-shaped clamping block 9 and the second U-shaped clamping block 12. Then, the two heat conducting cylinders 2 can be sleeved from the left and right sides of the upper end of the heating tube main body 1 until the lower ends of the two heat conducting cylinders 2 contact the arc-shaped elbow 6. Next, the first internal thread block 5 is screwed onto the outer parts of the first ceramic external thread tube 4 and the left external thread groove 13 by the thread principle, and the second internal thread block 11 is screwed onto the outer parts of the second ceramic external thread tube 10 and the right external thread groove 13 by the thread principle, and thus the overall installation of the heating tube main body 1 can be completed. The added honeycomb holes can reduce the overall weight of the two heat conducting cylinders 2 and the arc-shaped elbow 6 without affecting the heat dissipation and heat conduction of the heating tube main body 1, and the two heat conducting cylinders 2 and the arc-shaped elbow 6 are made of copper material with good heat conduction effect.
