[0022] The protection assembly 2 comprises a mounting frame 21 arranged on the outer frame 11, and a heat preservation assembly 3 and a self-cleaning assembly 4 are installed on the inner wall of the mounting frame 21 and are arranged away from the fin tubes 12 in sequence.
[0023] The heat preservation assembly 3 comprises a plurality of heat preservation pad layers 31 which are slidably installed on the inner side of the mounting frame 21 in the vertical direction of the mounting frame 21, each heat preservation pad layer 31 is arranged in one-to-one correspondence with each fin tube 12, and each heat preservation pad layer 31 is arranged in close contact with the fin tube 12 through a pressing assembly 5.
[0024] The self-cleaning assembly 4 comprises a plurality of vibrating scales 42 which are swingably installed on the inner wall of the mounting frame 21.
[0025] Specifically, the protection assembly 2 is installed on the outer frame 11 through the mounting frame 21, forming a protective layer covering the fin body 1 to isolate the external environment; the heat preservation pad layer 31 of the heat preservation assembly 3 is tightly attached to the fin tube 12 under the action of the pressing assembly 5, reducing heat loss; the vibrating scale 42 of the self-cleaning assembly 4 is in a shielding state under the condition of no wind force, isolating the external environment; the vibrating scale 42 vibrates under the action of wind force, realizing the automatic cleaning function.
[0026] Referring to Figures 4 to 5 A plurality of vertically corresponding longitudinal sliding grooves 32 are formed on the inner side of the mounting frame 21 at the upper and lower ends, a vertical rod 33 is slidably connected between each vertically corresponding longitudinal sliding groove 32, a C-shaped plate 34 is integrally arranged on one end of the vertical rod 33 close to the fin tube 12, the heat preservation pad layer 31 is fixedly arranged on the C-shaped plate 34, and the pressing assembly 5 is arranged in the longitudinal sliding groove 32 and makes the heat preservation pad layer 31 tightly attached to the surface of the fin tube 12.
[0027] Specifically, each longitudinal sliding groove one 32 is arranged corresponding to each finned tube 12 to avoid shielding the heat exchange air duct between adjacent finned tubes 12, and to ensure that the heat exchange efficiency of the finned tube 12 is not affected; the vertical rod 33 slides in the longitudinal sliding groove one 32, drives the C-shaped plate 34 and the thermal insulation pad 31 to move, and realizes the close adhesion of the thermal insulation pad 31 to the finned tube 12, thereby improving the thermal insulation effect.
[0028] Please refer to Figure 4 , the pressing assembly 5 includes a permanent magnet block one 51 fixedly embedded in the longitudinal sliding groove one 32 away from the fin body 1 on one side, and the vertical rod 33 is fixedly embedded with a permanent magnet block two 52 repelling the permanent magnet block one 51 away from the fin body 1 on one side.
[0029] Specifically, the permanent magnet block one 51 and the permanent magnet block two 52 of the pressing assembly 5 repel each other, push the vertical rod 33 to drive the C-shaped plate 34 and the thermal insulation pad 31 to closely adhere to the finned tube 12, thereby ensuring the thermal insulation effect. Each vertical rod 33 is independently arranged and is equipped with a pressing assembly 5, which can avoid the deviation of individual finned tubes 12 and thus reduce the thermal insulation effect.
[0030] Please refer to Figure 4 and Figures 6 to 7 , the inside of the mounting frame 21 is provided with a plurality of left and right corresponding longitudinal sliding grooves two 431 on both ends, and each longitudinal sliding groove two 431 is slidably provided with a cooperative vibration mechanism one 43, and the left and right corresponding cooperative vibration mechanisms one 43 are fixedly connected with a horizontal rod 41, and a plurality of vibration scales 42 are uniformly mounted on each horizontal rod 41 through a cooperative vibration mechanism two 44.
[0031] Specifically, the horizontal rod 41 balances the heat exchange wind force between the corresponding longitudinal sliding grooves two 431 through the cooperative vibration mechanism one 43, thereby forming a vibration effect. Under the synergistic action of the cooperative vibration mechanism two 44, different levels of vibration are generated, thereby driving the vibration scales 42 to present a complex vibration mode, thereby realizing the automatic cleaning function.
[0032] Please refer to Figure 6 , the cooperative vibration mechanism one 43 includes a sliding block 432, the sliding block 432 is fixedly embedded with a permanent magnet block three 433 away from the fin body 1 on one side, and the longitudinal sliding groove two 431 is fixedly embedded with a permanent magnet block four repelling the permanent magnet block three 433 away from the fin body 1 on one side.
[0033] Specifically, the permanent magnet block three 433 and the permanent magnet block four of the cooperative vibration mechanism one 43 repel each other, push the sliding block 432 to slide in the longitudinal sliding groove two 431, thereby driving the horizontal rod 41 to move, so that the horizontal rod 41 can automatically adjust the position according to the wind force, and form a resistance to the wind force, thereby realizing the first layer vibration cleaning effect. At the same time, this design can also strengthen the adhesion of the thermal insulation pad 31 to the finned tube 12, thereby further improving the thermal insulation performance. Please refer to Figure 7 The crossbar 41 comprises an axis connecting rod 411, a plurality of square rods 412 corresponding to the vibration scales 42 are rotatably sleeved on the axis connecting rod 411, and a clamping mechanism 6 for preventing the square rods 412 from rotating too much is arranged between the axis connecting rod 411 and the square rods 412. The clamping mechanism 6 comprises a clamping block one 61 integrally arranged on the outer periphery of the axis connecting rod 411, and a clamping block two 62 integrally arranged on the abutting surface of the square rods 412 and the axis connecting rod 411 and matched with the clamping block one 61.
[0034] Specifically, the axis connecting rod 411 is the core part of the crossbar 41, and a plurality of square rods 412 are rotatably sleeved thereon, and each square rod 412 corresponds to a vibration scale 42. This design enables each vibration scale 42 to independently swing by a certain angle. The clamping mechanism 6 further limits the rotation range of the square rods 412. Through the cooperation of the clamping block one 61 and the clamping block two 62, it is ensured that the square rods 412 will be limited after being rotated to a certain angle, preventing them from causing wind loss due to excessive rotation and affecting the overall vibration effect and stability. This design not only ensures the flexibility of the vibration scales 42, but also ensures their stability during vibration, thereby realizing efficient automatic cleaning function.
[0035] Please refer to Figure 7 Each of the square rods 412 is provided with a containing groove 441 on one side, the second vibration coordination mechanism 44 comprises a guide rod 442 arranged in the containing groove 441, permanent magnet blocks five 443 are fixedly arranged at both ends of the guide rod 442, the vibration scale 42 is slidably sleeved on the guide rod 442, and the vibration scale 42 is suspended between the two permanent magnet blocks five 443.
[0036] Specifically, the second vibration coordination mechanism 44 is arranged in the containing groove 441 of the square rod 412, and the structure is compact; the guide rod 442 provides a guide for the sliding of the vibration scale 42; the two permanent magnet blocks five 443 repel each other, so that the vibration scale 42 is suspended between them. When the crossbar 41 is vibrated due to wind force, the vibration scale 42 slides on the guide rod 442 and generates a complex vibration mode due to the action of the permanent magnet blocks five 443, thereby realizing the automatic cleaning function.
[0037] Please refer to Figure 7 The vibration scale 42 has a multilayer structure.
[0038] Please refer to Figure 7 The vibration scale 42 has a three-layer structure, which comprises an inner heat preservation layer, a middle vibration coordination layer, and an outer smooth isolation layer.
[0039] Specifically, the inner thermal insulation layer, the middle vibration assisting layer and the outer smooth isolation layer; the multi-layer vibration scale 42 can produce more complex and stronger vibration effect under the action of wind, compared with the single-layer structure, can more effectively remove the dust and sundries on the surface of the finned tube 12, further improve the cleaning effect, reduce the frequency and difficulty of manual cleaning, and reduce the operation and maintenance cost.
[0040] Please refer to Figures 1 to 4 The mounting frame 21 is fixedly provided with an elastic thermal insulation layer 7 close to the connecting surface of one end of the fin body 1.
[0041] Specifically, the elastic thermal insulation layer 7 can fill the gap between the mounting frame 21 and the fin body 1, strengthen the connection air tightness, further reduce heat loss, and effectively guarantee the heat preservation effect of the finned tube 12 together with the thermal insulation assembly 3, compared with the traditional heat preservation mode, can better maintain the system temperature, and does not affect the heat exchange efficiency.
[0042] The working principle of the application is as follows: when the heat preservation device for the fin of the air cooling system starts to work, the protection assembly 2 is stably installed on the outer frame 11 through the mounting frame 21, forming effective protection for the fin body 1. At this time, the thermal insulation pad layer 31 in the thermal insulation assembly 3 is tightly attached to the finned tube 12 under the action of the pressing assembly 5. Specifically, the permanent magnet block one 51 and the permanent magnet block two 52 in the pressing assembly 5 generate a pushing force due to the same polarity repulsion, push the vertical rod 33 to slide in the longitudinal sliding groove one 32, and then drive the C-shaped plate 34 and the thermal insulation pad layer 31 to approach and tightly attach to the finned tube 12, effectively reducing heat loss and guaranteeing the heat preservation effect of the finned tube 12.
[0043] At the same time, the self-cleaning assembly 4 starts to work. The permanent magnet block three 433 and the permanent magnet block four in the vibration assisting mechanism one 43 repel each other, push the sliding block 432 to slide in the longitudinal sliding groove two 431, drive the horizontal rod 41 to move. The horizontal rod 41 abuts against the vertical rod 33, further enhancing the attachment of the thermal insulation pad layer 31 to the finned tube 12. When the air cooling system is running, the wind blows out from the gap between the finned tubes 12 and generates a counterforce with the horizontal rod 41, realizing the first layer vibration cleaning effect and removing part of the dust and sundries on the surface of the vibration scale 42.
[0044] When there is no wind, the vibration scales 42 are in a shielding state under the action of gravity, forming a protective layer to isolate the external environment from the finned tube 12. When the wind hits the vibration scales 42, the permanent magnet block 443 in the coordination vibration mechanism 44 makes the vibration scales 42 in a suspended state, and the suspension force of the vibration scales 42 and the wind force form a counterforce, generating a second layer of vibration cleaning effect. Moreover, the multi-layer structure of the vibration scales 42 can generate complex vibration modes of different frequencies and amplitudes under the action of wind, enhancing the cleaning effect and preventing dust and debris from accumulating. In addition, the clamping mechanism 6 on the shaft connecting rod 411 is positioned when the vibration scales 42 are opened to a certain angle, and a third layer of vibration cleaning effect is achieved under the impact of wind.
[0045] The square bar 412 rotates along the shaft connecting rod 411 to open, ensuring the flow of wind for heat exchange treatment and ensuring the normal operation of the air cooling system. The elastic heat preservation layer 7 of the mounting frame 21 near one end of the fin body 1 enhances the connection air tightness, further ensuring the heat preservation performance. The entire device improves the heat preservation effect and heat exchange efficiency of the fin of the air cooling system through heat preservation, automatic adjustment and self-cleaning functions, and reduces the operation and maintenance cost.
