[0002] The star-shaped finned tubes on the ambient air vaporizer play an important role and significance in the ambient air vaporization process. As the core part of the heat exchange device, the star-shaped finned tubes can obtain heat energy from the atmosphere and realize the liquid endothermic vaporization process through heat transfer with the vaporization medium. The design of the finned tubes gives them a large surface area, increasing the contact area with the surrounding air, thereby effectively exchanging heat and improving the vaporization efficiency.

[0003] According to the star-shaped finned tube for an ambient air vaporizer disclosed in patent publication number CN 221006016 U, the U-shaped connecting tube of this device is threadedly connected to the central tube of two adjacent star-shaped finned heat dissipation tubes through a sleeve. Compared with the traditional welding technology, the threaded connection is simpler and does not require complicated welding equipment and technology, which makes the installation and maintenance of the U-shaped connecting tube more convenient. However, when replacing or repairing the U-shaped tube, the sleeve needs to be rotated multiple times, which is inconvenient for disassembly and assembly, thus affecting the replacement efficiency.

[0015] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0016] Example 1 like Figure 1-5 As shown, this utility model provides a technical solution: a high-efficiency heat transfer type air-temperature vaporizer finned tube, including a central tube 1, a U-shaped tube 2 disposed on one side of the central tube 1, a mounting sleeve 4 fixedly installed at the end of the U-shaped tube 2, and a connecting assembly 3 disposed between the central tube 1 and the U-shaped tube 2. The connecting assembly 3 includes a mounting mechanism 31 disposed between the central tube 1 and the U-shaped tube 2. A heat transfer mechanism 32 is disposed inside the central tube 1. The mounting sleeve 4 is connected to the U-shaped tube 2. The mounting mechanism 31 includes a sealing gasket 31 fixedly connected to the inner wall of the mounting sleeve 4. 1. The mounting sleeve 4 has an internal movable groove 312. A movable block 313 is slidably connected to the inner wall of the movable groove 312. An inclined plate 314 is fixedly connected to one side of the movable block 313. A connecting rod 315 is fixedly connected to the side of the movable block 313 away from the inclined plate 314. A first spring 316 is fixedly connected to the inner wall of the movable groove 312. A guide push plate 317 is fixedly connected to the outer end of the connecting rod 315. A positioning groove 3110 is opened in the inner wall of the mounting sleeve 4. A positioning block 318 is fixedly connected to the outer wall of the central tube 1. A slot 319 is opened in the outer wall of the central tube 1.

[0017] In this embodiment, the inclined plate block 314 is movably inserted through the movable groove 312, and the inclined plate block 314 is engaged with the groove 319. Through the cooperation of the sealing gasket 311, the movable groove 312, the movable block 313, the inclined plate block 314, the connecting rod 315, the first spring 316, the guide push plate 317, the positioning block 318, the groove 319, and the positioning groove 3110, it is convenient for manual disassembly and assembly of the U-shaped tube 2, thereby facilitating manual repair or replacement of the U-shaped tube 2, and the disassembly and assembly operation is simple and convenient.

[0018] Furthermore, the outer end of the connecting rod 315 extends through the movable groove 312, and one end of the first spring 316 is fixedly connected to the movable block 313.

[0019] When installing the central tube 1 and the U-shaped tube 2, simply insert the mounting sleeve 4 into the port of the central tube 1 manually, and engage the positioning block 318 fixed to the outer wall of the central tube 1 with the positioning groove 3110. This facilitates the subsequent alignment of the inclined plate block 314 and the groove 319. Then, press the mounting sleeve 4 inward. When the end of the central tube 1 enters the mounting sleeve 4, the inclined plate block 314, being inclined on the outside, presses against it, causing it to be pushed into the movable groove 312. At this time, the first spring 316 is compressed, allowing the central tube 1 to continue moving into the mounting sleeve 4, thus making the end of the central tube 1 press against the sealing gasket 311. Under the action of the spring 316, the movable block 313 can drive the inclined plate block 314 to move inward, thereby allowing the fixed inclined plate block 314 to engage with the slot 319, thus fixing the central tube 1 inside the mounting sleeve 4, thus completing the installation operation of the central tube 1 and the U-shaped tube 2. When disassembling the U-shaped tube 2, it is only necessary to manually push the guide plate 317 outward, thereby allowing the connecting rod 315 fixedly connected to the inner side of the guide plate 317 to drive the movable block 313 to move outward, thereby allowing the inclined plate block 314 fixedly connected to one side of the movable block 313 to separate from the slot 319. Then, the U-shaped tube 2 can be manually removed outward, which facilitates manual maintenance or replacement of the U-shaped tube 2. The disassembly and assembly of the U-shaped tube 2 is simple and convenient, increasing the applicability of the device.

[0020] Example 2 Based on Example 1, a preferred embodiment of the high-efficiency heat transfer type air-temperature vaporizer finned tube provided by this utility model is, for example... Figures 1 to 5 As shown: The heat transfer mechanism 32 includes a limiting ring 321 fixedly connected to the outer wall of the central tube 1, heat exchange fins 322 installed on the outside of the U-shaped tube 2, a connector 323 fixedly installed on the outer end of the heat exchange fins 322, short protrusions 324 and long protrusions 325 fixedly connected to the inner wall of the port of the central tube 1 respectively, and spiral baffles 326 installed inside the central tube 1.

[0021] In this embodiment, the positioning block 318 is snapped into the positioning groove 3110. Through the cooperation of the limiting ring 321, heat exchange fins 322, connector 323, short protrusion 324, long protrusion 325, and spiral baffle 326, the heat conduction and heat exchange between the medium and the inner wall of the central tube 1 can be enhanced, thereby improving the heat exchange effect.

[0022] Furthermore, there are several heat exchange fins 322, which are equidistantly distributed on the outside of the central tube 1.

[0023] In use, the device increases the heat exchange surface area by setting short protrusions 324 and long protrusions 325 on the inner wall of the port of the central tube 1, and expands the contact area between the inner walls of both ends of the central tube and the medium, thereby providing more heat exchange surface and realizing heat transfer more effectively. At the same time, the groove formed between the short protrusions 324 and long protrusions 325 can change the flow characteristics of the medium and generate turbulence effect, which can enhance the heat conduction and heat exchange between the medium and the central tube 1 and the heat exchange fins 322. Furthermore, the spiral turbulence plate 326 can disturb the medium and introduce irregularity and turbulence. Compared with laminar flow, turbulence has a greater stirring and mixing effect, which can enhance the heat conduction and heat exchange between the medium and the inner wall of the finned tube. At the same time, turbulence can increase the rate and efficiency of heat transfer, thereby further improving the heat exchange efficiency.
