Description

Technical Field

[0001] This utility model relates to the field of finned tube heat exchanger technology, specifically a finned tube heat exchanger that is easy to install. Background Technology

[0002] Finned heat exchangers are the most widely used heat exchange equipment in gas-liquid heat exchangers. They enhance heat transfer by adding fins to ordinary base tubes. The base tubes can be made of steel, stainless steel, copper, etc., and the fins can be made of steel strips, stainless steel strips, copper strips, aluminum strips, etc.

[0003] According to a public notice regarding a finned tube heat exchanger designed for easy maintenance (Notice No.: CN217131916U3), the aforementioned application utilizes a driving moving component to allow one end of an L-shaped plate to enter a fixed frame, facilitating the installation of the finned tube heat exchanger within the mounting frame. This makes it easier to disassemble and maintain the finned tube heat exchanger later, avoiding the cumbersome disassembly and maintenance associated with bolt-fixed finned tube heat exchangers. The finned tube heat exchanger, designed for easy maintenance, uses a driving component to move a pushing plate, allowing the heat exchanger body to be easily removed from the mounting frame, thus improving the maintenance efficiency for staff.

[0004] However, in actual use, the above-mentioned equipment requires manual pulling of the moving parts to install and disassemble the finned tube heat exchanger. The drive components on both sides cannot synchronously and effectively fix the finned heat exchanger, resulting in an unstable fixing effect. In view of this, we propose a finned tube heat exchanger that is easy to install. Utility Model Content

[0005] The purpose of this invention is to provide a finned tube heat exchanger that is easy to install, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A finned tube heat exchanger that is easy to install includes a mounting frame. An installation groove is formed on the upper inner surface of the mounting frame, and a guide groove is formed on the side wall of the installation groove. An equipment groove and a limiting groove are formed inside the mounting frame. An installation mechanism is provided within the limiting groove. The installation mechanism includes:

[0007] A limiting plate, wherein the side wall of the limiting groove is slidably connected to the side wall of the limiting plate, and a telescopic sleeve is fixedly connected to the bottom surface of the limiting plate. A telescopic spring is sleeved on the outer surface of the telescopic sleeve. One end of the telescopic spring is fixedly connected to the lower surface of the limiting plate, and the other end of the telescopic spring is fixedly connected to the bottom surface of the limiting groove.

[0008] The connecting frame has the upper surface of the limiting plate fixedly connected to the lower surface of the connecting frame, a first toothed plate fixedly connected to one side of the inner wall of the connecting frame, a fixed shaft rotatably connected to the side wall of the equipment slot, a rotating gear fixedly connected to the outer surface of the fixed shaft, a second toothed plate meshing with the lower surface of the rotating gear, and a limiting block fixedly connected to the fixed end of the second toothed plate.

[0009] Preferably, a sliding groove is provided at the end of the equipment groove, a limiting block is slidably connected to the inner wall of the sliding groove, a baffle is fixedly connected to the end of the limiting block away from the installation groove, a handle is fixedly connected to the end of the baffle away from the limiting block, and a sliding plate is slidably connected to the side wall of the limiting groove.

[0010] Preferably, the length of the limiting groove matches the size of the limiting block, and a rubber plate is fixedly connected to the upper surface of the limiting plate, and a silicone pad is fixedly connected to the end of the limiting block away from the handle.

[0011] Preferably, the number of installation mechanisms is set to multiple sets, and the multiple sets of installation mechanisms are distributed in a mirror-symmetrical manner inside the limiting grooves and equipment grooves at both ends of the installation frame.

[0012] Preferably, an auxiliary mechanism is provided at the end of the limiting block away from the baffle. The auxiliary mechanism includes a telescopic rod. A circular groove is provided at the end of the limiting block away from the baffle. The bottom surface of the circular groove is fixedly connected to one end of the telescopic rod. A fixing block is fixedly connected to the other end of the telescopic rod. A telescopic spring is sleeved on the outer surface of the telescopic rod.

[0013] Preferably, the shape of the fixing block is set to an arc, and the size of the fixing block matches the size of the circular groove.

[0014] Preferably, the size of the equipment slot matches the size of the limiting block, and the size of the limiting block is greater than the width of both ends of the mounting frame.

[0015] Compared with the prior art, this utility model provides a finned tube heat exchanger that is easy to install and has the following advantages:

[0016] 1. This easy-to-install finned tube heat exchanger, through its installation mechanism and components including a limiting plate, telescopic sleeve, telescopic spring one, connecting frame, first toothed plate, rotating gear, and second toothed plate, achieves quick and stable installation of the heat exchanger core. When installation is required, the operator simply places the core into the installation slot and presses down the connecting frame. This drives the limiting plate to move downwards against the resistance of the telescopic spring one, simultaneously moving the first toothed plate. The first toothed plate drives the rotating gear to rotate, which in turn moves the meshing second toothed plate and the limiting block laterally, causing them to extend from the equipment slot and lock the heat exchanger core. After release, the limiting block automatically maintains its locked state under the reset action of the telescopic spring one.

[0017] 2. This easy-to-install finned tube heat exchanger features an auxiliary mechanism. During installation, when the limiting block is pressed against the heat exchanger core surface, the fixed block, under pressure, retracts along the telescopic rod into the circular groove inside the limiting block, simultaneously compressing the second telescopic spring. The arc-shaped design provides a good guiding contact surface. The elastic force generated by the second telescopic spring ensures the fixed block fits tightly against the core surface, effectively absorbing vibrations or minor impacts during installation and use, protecting the core from damage. The adaptive adjustment of the spring force can compensate for minor tolerances in the finned tube diameter or slight installation deviations. Attached Figure Description

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a finned tube heat exchanger that is easy to install, including a mounting frame 1. The upper surface of the mounting frame 1 is provided with a mounting groove 11, and the side wall of the mounting groove 11 is provided with a guide groove 12. The inside of the mounting frame 1 is provided with an equipment groove 13 and a limiting groove 14. An installation mechanism 2 is provided in the limiting groove 14. The installation mechanism 2 includes: a limiting plate 21, a telescopic sleeve 22, a telescopic spring 23, a sliding plate 24, a connecting frame 25, a first toothed plate 26, a fixed shaft 27, a rotating gear 28, a second toothed plate 29, a limiting block 210, a baffle 211, and a handle 212.

[0024] In one embodiment of this utility model, the sidewall of the limiting groove 14 is slidably connected to the sidewall of the limiting plate 21. A telescopic sleeve 22 is fixedly connected to the bottom surface of the limiting plate 21. A telescopic spring 23 is sleeved on the outer surface of the telescopic sleeve 22. One end of the telescopic spring 23 is fixedly connected to the lower surface of the limiting plate 21, and the other end of the telescopic spring 23 is fixedly connected to the bottom surface of the limiting groove 14. The telescopic spring 23 can ensure that the limiting plate 21 can be reset during the disassembly of the heat exchanger. The upper surface of the limiting plate 21 is fixedly connected to the lower surface of the connecting frame 25. A first toothed plate 26 is fixedly connected to one side of the inner wall of the connecting frame 25. A fixed shaft 27 is rotatably connected to the side wall of the equipment slot 13. A rotating gear 28 is fixedly connected to the outer surface of the fixed shaft 27. When the limiting plate 21 moves vertically downward or upward, it will synchronously drive the connecting frame 25 to move. Furthermore, the first toothed plate 26 on the inner side of the connecting frame 25 will drive the rotating gear 28 to rotate. A second toothed plate 29 meshes with the lower surface of the rotating gear 28. A limiting block 210 is fixedly connected to the fixed end of the second toothed plate 29. When the rotating gear 28 rotates, it will synchronously drive the connecting frame 25 to move. The second toothed plate 29 is moved by the step. Because the size of the second toothed plate 29 is smaller than the size between the connecting frames 25, the second toothed plate 29 will not affect the normal vertical movement of the connecting frames 25. A sliding groove is provided at the end of the equipment groove 13. A limit block 210 is slidably connected to the inner wall of the sliding groove. A baffle 211 is fixedly connected to the end of the limit block 210 away from the mounting groove 11. A handle 212 is fixedly connected to the end of the baffle 211 away from the limit block 210. The baffle 211 can block the outer wall of the sliding groove, so that the limit block 210 will not fall out of the sliding groove. By pulling the handle 212, the limit block 210 can be moved. 12 allows for the disassembly of the heat exchanger. The side wall of the limiting groove 14 is slidably connected to a sliding plate 24, which protects the normal operation of the telescopic spring 23. The length of the limiting groove 14 matches the size of the limiting block 210, making the limiting block 210 more compatible with the entire installation mechanism 2. A rubber plate is fixedly connected to the upper surface of the limiting plate 21, and a silicone pad is fixedly connected to the end of the limiting block 210 away from the handle 212. This increases friction to ensure stability while preventing damage to the outer surface of the heat exchanger caused by rigid connection.

[0025] Additionally, an auxiliary mechanism 3 is provided at the end of the limiting block 210 away from the baffle 211. The auxiliary mechanism 3 includes a telescopic rod 31. A circular groove is formed at the end of the limiting block 210 away from the baffle 211. The bottom surface of the circular groove is fixedly connected to one end of the telescopic rod 31. A fixing block 33 is fixedly connected to the other end of the telescopic rod 31. A telescopic spring 32 is sleeved on the outer surface of the telescopic rod 31. The fixing block 33 is arc-shaped, and its size matches the size of the circular groove. By providing the auxiliary mechanism 3, when the limiting block 210 presses against the surface of the heat exchanger core during installation, the core is fixed. When subjected to pressure, block 33 can retract along the telescopic rod 31 into the circular groove inside the limiting block 210, while simultaneously compressing the telescopic spring 32. This allows the entire auxiliary mechanism 3 to better fit the outer surface of the heat exchanger. The arc-shaped design provides a good guiding contact surface, enabling better installation and disassembly of the heat exchanger. The elastic force generated by the telescopic spring 32 allows the fixing block 33 to fit tightly against the core surface, effectively absorbing vibrations or minor impacts during installation and use, protecting the core from damage. Through adaptive adjustment of the spring force, it can compensate for minor tolerances in the finned tube diameter or slight installation deviations.

[0026] In the embodiments of this utility model, multiple sets of installation mechanisms 2 are provided, and the multiple sets of installation mechanisms 2 are distributed in a mirror symmetrical manner inside the limiting grooves 14 and equipment grooves 13 at both ends of the mounting frame 1. By designing the installation mechanisms 2 at both ends of the mounting grooves 11, a stable fixing force can be provided to the heat exchanger. The shape of the fixing block 33 is set as an arc, and the size of the fixing block 33 matches the size of the circular groove, which can ensure the smooth and stable operation of the auxiliary mechanism 3. The size of the equipment groove 13 matches the size of the limiting block 210, so that the limiting block 210 is not affected by the equipment groove 13 during the movement, thus ensuring the stable operation of the entire installation mechanism 2. Furthermore, the size of the limiting block 210 is greater than the width of both ends of the mounting frame 1, and the length of the limiting block 210 is greater than the width of the mounting frame 1, which can ensure the stable fixing force of the installation mechanism 2.

[0027] In this utility model, during use, the two ends of the heat exchanger are placed close to the upper surface of the limiting plate 21. At this time, the limiting plate 21 will move downward along the limiting groove 14. Furthermore, the connecting frame 25, which is fixedly connected to the upper surface of the limiting plate 21, moves downward, driving the first toothed plate 26 to move downward. Furthermore, the rotating gear 28 rotates, driving the second toothed plate 29 and the limiting block 210 to slide into the mounting groove 11, clamping the heat exchanger. At the same time, because the baffle 211 is provided, it can prevent the limiting block 210 from moving excessively. The fixing block 33 abuts against the heat exchanger, and the extension spring 32 further clamps it. When disassembly is required, the handle 212 can be pulled to unlock the clamping and fixing of the heat exchanger, making it easy for the staff to remove the heat exchanger.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
