Technical Field

[0001] This utility model relates to the field of finned condenser technology, and in particular to a finned condenser tube assembly anti-loosening fixing device. Background Technology

[0002] A finned condenser is a device that transfers heat by enhancing the heat exchange surface. Its core principle is to transfer the heat released by the refrigerant when it flows inside the tube through the tube wall to the dense "fins" on the outside, and then carry away the heat with the help of air (natural convection or forced convection). Finally, the high-temperature and high-pressure refrigerant inside the tube condenses from a gaseous state to a liquid state, completing the "heat release" stage in the refrigeration cycle.

[0003] The existing methods for fixing finned condenser tube assemblies mostly use simple tube clamps or cable ties. These fixing structures lack effective anti-loosening designs. Under long-term vibration conditions caused by compressor operation, the fixing components are prone to fatigue and loosening, thus failing to achieve stable fixing of the tube assembly.

[0004] To address this, a device for preventing loosening of finned condenser tube bundles is proposed. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 The present invention provides the following technical solution:

[0027] A finned condenser tube assembly anti-loosening fixing device includes a mounting base 1, a finned tube assembly 2 is provided on the top of the mounting base 1, and fixing components 3 that cooperate with the finned tube assembly 2 are provided on the front and rear sides of the top of the mounting base 1. Anti-loosening limiting components 4 are provided on both sides of the fixing components 3.

[0028] The fixing component 3 includes a lower fixing plate 31 and an upper fixing plate 32. A fixing plate 33 is fixedly connected to the bottom of the lower fixing plate 31. Multiple damping shock absorbers 34 are fixedly connected to the bottom of the fixing plate 33. The bottom of the damping shock absorbers 34 is fixedly connected to the top of the base. Multiple arc-shaped slots 35 are provided on the top of the lower fixing plate 31 and the bottom of the upper fixing plate 32. First connecting blocks 36 are fixedly connected to the bottom of both sides of the upper fixing plate 32. Second connecting blocks 37 are fixedly connected to the top of both sides of the lower fixing plate 31. A fixing bolt 38 is provided on the top of the first connecting block 36. The bottom of the fixing bolt 38 passes through the first connecting block 36 and the second connecting block 37 in sequence.

[0029] In this embodiment: by setting up a mounting base 1, a finned tube assembly 2, a fixing component 3, and an anti-loosening limiting component 4, during use, the mounting base 1 provides a mounting and fixing foundation for the finned tube assembly 2, the fixing component 3, and the anti-loosening limiting component 4. The fixing component 3 can stably fix the finned tube assembly 2 and absorb the vibration energy generated during condenser operation, reducing the impact of vibration on the finned tube assembly 2 and preventing fatigue damage and loosening of the finned tube assembly 2 due to long-term high-frequency vibration. The anti-loosening limiting component 4 can limit and lock the key connection parts of the fixing component 3, preventing the fixing component from loosening and failing under long-term vibration, temperature changes, and other operating conditions. Even in extreme scenarios of high-frequency vibration of the condenser, it can ensure that the fixing component 3 always maintains a stable fixed state, thereby effectively solving the problem of finned tube assembly loosening.

[0030] Specifically, such as Figure 1 , Figure 4 , Figure 5 As shown, the anti-loosening limiting component 4 includes a rotating shaft 41. The bottom of the rotating shaft 41 is fixedly connected to one side of the top of the upper fixed plate 32. A connecting strip 42 is rotatably connected to the surface of the rotating shaft 41 via a bearing. A positioning block 43 is fixedly connected to the side of the connecting strip 42 away from the top center of the upper fixed plate 32. A spring 44 is fixedly connected to the bottom of the positioning block 43. An anti-loosening limiting sleeve 45 is fixedly connected to the bottom of the spring 44. The internal shape of the anti-loosening limiting sleeve 45 is the same as the shape of the bolt head of the fixing bolt 38. The anti-loosening limiting sleeve 45 is fitted onto the surface of the bolt head of the fixing bolt 38.

[0031] Specifically, such as Figure 1 , Figure 4 , Figure 5 As shown, the top of the anti-loosening limiting sleeve 45 is fixedly connected to a limiting strip 46, and the top of the limiting strip 46 passes through the spring 44 and the positioning block 43 in sequence and is fixedly connected to a handle 47.

[0032] Specifically, such as Figure 5As shown, the bottom of the positioning block 43 has a square opening 5 that works in conjunction with the limiting strip 46, and the surface of the limiting strip 46 is slidably connected to the inner wall of the square opening 5.

[0033] In this embodiment: by setting a rotating shaft 41, connecting bar 42, positioning block 43, spring 44, release limit sleeve, limit bar 46, handle 47, and square opening 5, in use, first pull the handle 47 upward to drive the limit bar 46 to slide upward along the square opening 5 of the positioning block 43. The limit bar 46 simultaneously pulls the anti-loosening limit sleeve 45 upward, so that the spring 44 between the anti-loosening limit sleeve 45 and the positioning block 43 is compressed. Then, with the rotating shaft 41 as the center, rotate the connecting bar 42 so that the connecting bar 42... The positioning block 43, spring 44, and anti-loosening limit sleeve 45 are rotated to be directly above the bolt head of the fixing bolt 38. Then, the handle 47 is released, the spring 44 returns to its elastic deformation, and pushes the anti-loosening limit sleeve 45 downward, so that the anti-loosening limit sleeve 45 is precisely fitted onto the bolt head surface of the fixing bolt 38. At this time, the anti-loosening limit sleeve 45 tightly fits the bolt head of the fixing bolt 38 through the thrust of the spring 44, restricting the rotation of the bolt head, thereby effectively preventing the fixing bolt 38 from loosening due to vibration and other factors.

[0034] Specifically, such as Figure 1 , Figure 3 As shown, a rubber pad 6 is fixedly connected inside the arc-shaped groove 35, and the inner side of the rubber pad 6 is tightly attached to the surface of the heat exchange tube of the finned tube assembly 2.

[0035] Specifically, such as Figure 6 As shown, the top of the first connecting block 36 and the second connecting block 37 are both provided with threaded holes 7 for use with fixing bolts 38, and the surface of the fixing bolts 38 is connected to the inner wall of the threaded holes 7 by threads.

[0036] In this embodiment: by setting the rubber pad 6, not only can the friction be increased to prevent the heat exchange tube of the finned tube assembly 2 from sliding, but the tube body can also be avoided from being damaged by hard compression. By setting the threaded hole 7, the fixing bolt 38 can pass through the first connecting block 36 and the second connecting block 37 and be connected and fixed by the thread.

[0037] Specifically, such as Figure 1 , Figure 2 As shown, side baffles 8 are fixedly connected to both sides of the top of the mounting base 1. The side baffles 8 are in contact with the heat dissipation fins of the finned tube assembly 2 on the side closest to the heat dissipation fins of the finned tube assembly 2.

[0038] Specifically, such as Figure 1 , Figure 2 As shown, multiple mounting blocks 9 are fixedly connected to both sides of the mounting base 1, and mounting holes 10 are provided on the top of the mounting blocks 9.

[0039] In this embodiment: by setting the side baffle 8, the heat dissipation fins of the finned tube assembly 2 can be laterally limited and protected. By setting the mounting block 9 and the mounting hole 10, the mounting base 1 can be installed and fixed to the condenser by bolts.

[0040] Working principle: In use, first place the finned tube assembly 2 on the two lower fixing plates 31 on the top of the mounting base 1, and insert the heat exchange tubes of the finned tube assembly 2 into the corresponding arc-shaped grooves 35 on the lower fixing plate 33. Then, cover the lower fixing plate 31 with the upper fixing plate 32, so that the arc-shaped groove 35 at the bottom of the upper fixing plate 32 is in contact with the top of the heat exchange tubes of the finned tube assembly 2. At this time, the rubber pad 6 in the arc-shaped groove 35 is in close contact with the surface of the heat exchange tubes of the finned tube assembly 2, which not only enhances the friction to prevent the heat exchange tubes of the finned tube assembly 2 from sliding, but also avoids hard squeezing and damage to the tube body. Then, tighten the fixing bolts 38 from the first... A connecting block 36 is inserted and rotated at its top, allowing the fixing bolt 38 to pass through the first connecting block 36 and the second connecting block 37 sequentially via threads. This connects and fixes the first connecting block 36 and the second connecting block 37 via threads. After tightening the fixing bolt 38, the upper fixing plate 32 and the lower fixing plate 31 clamp the heat exchange tubes of the finned tube assembly 2 together through the arc-shaped groove 35, achieving initial stable fixation of the finned tube assembly 2. At the same time, the damping shock absorber 34 at the bottom of the lower fixing plate 31 is in a natural support state, preparing for subsequent vibration absorption. After fixing, the handle 47 can be pulled upwards to move the limiter. The positioning bar 46 slides upward along the square opening 5 of the positioning block 43. Simultaneously, the limiting bar 46 pulls the anti-loosening limiting sleeve 45 upward, compressing the spring 44 between the anti-loosening limiting sleeve 45 and the positioning block 43. Then, with the pivot 41 as the center, the connecting bar 42 rotates, causing the positioning block 43, spring 44, and anti-loosening limiting sleeve 45 to rotate directly above the bolt head of the fixing bolt 38. Then, the handle 47 is released, and the spring 44 returns to its elastic deformation, pushing the anti-loosening limiting sleeve 45 downward, ensuring that the anti-loosening limiting sleeve 45 precisely engages with the bolt head surface of the fixing bolt 38. At this point, the anti-loosening limiting sleeve 45... The spring 44 tightly grips the bolt head of the fixing bolt 38, restricting the rotation of the bolt head. This effectively prevents the fixing bolt 38 from loosening due to vibration or other factors. After this device is installed on the condenser, during the operation of the condenser, the vibration generated by the compressor and fan will be transmitted to the damping shock absorber 34 through the mounting base 1. The damping shock absorber 34 absorbs the vibration energy through its own damping characteristics, reducing the transmission of vibration to the fixing component 3 and the finned tube assembly 2. This effectively reduces the impact of vibration on the finned tube assembly 2 and prevents the finned tube assembly 2 from fatigue damage and loosening due to long-term high-frequency vibration.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
