Description

Technical Field

[0001] This invention relates to the field of air-cooled equipment technology, specifically a detachable noise reduction structure and an air-cooled device containing the structure. Background Technology

[0002] Air cooling is a type of cooling method that uses air as a medium to cool the object that needs to be cooled. This typically involves increasing the surface area of ​​the object, increasing the rate at which air flows over it per unit time, or a combination of both. The former can be achieved by adding heat sinks to the object's surface, usually hanging them on the outside or fixing them to the object for more efficient heat dissipation. The latter uses fans to enhance ventilation and improve cooling. Sound-absorbing materials, such as sound-absorbing cotton or fiberglass, are used on the inner walls of the air-cooled equipment's casing or ventilation ducts; these materials absorb noise generated during operation and reduce noise propagation.

[0003] The patent with authorization announcement number CN222835978U describes a fan noise reduction structure. This structure solves the problems of reduced lifespan of the drive structure, noise reduction structure causing difficulty in heat dissipation, and cooling structure affecting the use of high-temperature airflow when the fan is used in applications requiring high-temperature airflow. The structure also addresses the issues of the fan noise reduction structure often needing to be manufactured according to the fan size, and the fan generating more noise when the air outlet and air inlet pipes are at a certain angle.

[0004] However, the noise reduction structure described in the aforementioned patent still has many shortcomings in practical use. On the one hand, the fixed connection between the noise reduction structure and the fan makes the disassembly and replacement of both extremely inconvenient. If the fan or noise reduction structure malfunctions or requires an upgrade, the repair and replacement work is time-consuming and labor-intensive, significantly reducing equipment maintenance efficiency. On the other hand, noise reduction through sound-absorbing panels surrounding the fan can only reduce some of the noise generated by fan vibration. The noise reduction effect is not ideal for the noise generated by airflow impact and friction at the fan's inlet and outlet.

[0005] Based on this, a detachable noise reduction structure and an air-cooling device containing the structure are provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In one embodiment, such as Figures 1-8 As shown, a detachable noise reduction structure includes a noise reduction mechanism 100. The noise reduction mechanism 100 includes a mounting base 200 for installing air-cooled equipment, a sound-absorbing module 300 disposed at the air inlet end of the air-cooled equipment, and a sound-absorbing module 400 disposed at the air outlet end of the air-cooled equipment. The air-cooled equipment is bolted to the mounting base 200, and both the sound-absorbing module 300 and the sound-absorbing module 400 are threaded to the air-cooled equipment. During installation, the air-cooled equipment is first installed on the mounting base 200, then the sound-absorbing module 300 is installed at the air inlet end of the air-cooled equipment, and the sound-absorbing module 400 is installed at the air outlet end of the air-cooled equipment. Through the combined action of the mounting base 200, the sound-absorbing module 300, and the sound-absorbing module 400, noise reduction of the air-cooled equipment is achieved.

[0028] In one embodiment, such as Figure 2As shown, the mounting base 200 includes a base 201, with two movable seats 202 symmetrically hinged on both sides of the base 201. A first support seat 203 is provided in the middle of the base 201. Semi-circular mounting grooves 204 are provided on the base 201 and the first support seat 203. A first rubber pad 205 is provided on the semi-circular mounting grooves 204. Four tension springs 206 are symmetrically provided on the bottom plate of the base 201. Bolt holes 213 for installing air-cooled equipment are provided at both ends of the base 201 and the movable seats 202. A second support seat 207 is provided in the middle of the movable seat 202. A quarter-circular mounting groove 208 is provided on both the movable seat 202 and the second support seat 207. A second rubber pad 209 is provided on the quarter-circular mounting groove 208. An electric telescopic rod 210 is provided inside the movable seat 202. An arc-shaped pressure plate 211 is provided at the output end of the electric telescopic rod 210. A side of the movable seat 202 is provided with The connecting blocks 212 are connected by bolts. During installation, the air-cooled equipment is placed in the semi-circular mounting groove 204, and then the tension spring 206 is connected to the lower end of the air-cooled equipment. Next, the two movable seats 202 are closed so that the quarter-circular mounting groove 208 is locked onto the upper end of the air-cooled equipment, and the connecting blocks 212 are fixed by bolts. Then, the two ends of the air-cooled equipment are bolted to the bolt holes 213 at both ends of the mounting seat 200. Then, the electric telescopic rod 210 is extended to drive the arc-shaped pressure plate 211 to provide lateral pressure to the air-cooled equipment. The arc-shaped pressure plate 211 is equipped with a pressure sensor to control the pressure. During the use of the air-cooled equipment, the vibration of the air-cooled equipment is limited by the combined action of the tension spring 206, the arc-shaped pressure plate 211, the first rubber pad 205, and the second rubber pad 209, thereby reducing the noise caused by vibration.

[0029] In one embodiment, such as Figure 3 As shown, the sound-absorbing module 300 includes a porous sound-absorbing cover 301. One end of the porous sound-absorbing cover 301 is provided with a first connecting seat 302. The inner side of the first connecting seat 302 is provided with a first internal thread 303. The inner side of the porous sound-absorbing cover 301 is provided with a plurality of sound-absorbing holes 304. The inner side of the porous sound-absorbing cover 301 is also provided with sound-absorbing plates 305 that have a guiding function. During installation, the first connecting seat 302 of the sound-absorbing module 300 is connected to the external thread of the air inlet end of the air-cooling equipment. The sound-absorbing module 300 is fixed to the air inlet end of the air-cooling equipment by rotating the thread. The sound-absorbing holes 304 can absorb noise in the air entering the air-cooling equipment. The sound-absorbing plates 305 play a guiding role, so that the air enters the air-cooling equipment more evenly and reduces the noise generated by the airflow impact.

[0030] In one embodiment, such as Figures 4-6As shown, the silencing module 400 includes a silencing box 401. One end of the silencing box 401 has a second connecting seat 402, and the inner side of the second connecting seat 402 has a second internal thread 403. The silencing box 401 contains a silencing plate assembly 500, and the silencing plate assembly 500 has a driving component 600. The silencing plate assembly 500 includes several silencing plates 501 arranged at equal intervals within the silencing box 401. One side of each silencing plate 501 has a fixed shaft 502, both ends of which are rotatably connected to the silencing box 401. The side of the silencing plate 501 opposite to the fixed shaft 502 has a connecting post 503, and a connecting rod 504 is rotatably mounted on the connecting post 503. The driving component 600 includes a linkage rod 601, the middle of which is rotatably mounted on the upper end of the silencing box 401 via a rotating shaft 602. One end of the linkage rod 601 is connected to the fixed shaft 504 at the upper end of one of the silencing plates 501 through a connecting hole 603. A fixed shaft 502 is fixedly connected, and a strip groove 604 is provided at the other end of the linkage rod 601. A gantry frame 605 is provided above the strip groove 604, and a motor 606 is provided on the gantry frame 605. A circular plate 607 is provided on the output shaft of the motor 606, and a drive column 608 is provided at the lower end of the circular plate 607. The drive column 608 is slidably installed in the strip groove 604. During installation, the second connecting seat 402 of the silencing module 400 is connected to the external thread of the air outlet of the air-cooled equipment. The silencing module 400 is fixed to the air outlet of the air-cooled equipment by rotating the thread. After the motor 606 is powered on, the circular plate 607 rotates and drives the drive column 608 to slide in the strip groove 604. Through the transmission of the linkage rod 601, the silencing plate 501 swings back and forth around the fixed shaft 502, extending the sound wave reflection path. Through multiple reflections, the sound energy is consumed, thereby reducing the noise diffused outward during the operation of the air-cooled equipment and reducing noise pollution.

[0031] The present invention also provides an air-cooled device, such as... Figure 7 and Figure 8 As shown, the device includes a fan 700 and the aforementioned detachable noise reduction structure. The fan 700 has third connecting seats 701 at both ends for connection to the mounting base 200, and a fourth connecting seat 702 at the lower end for connection to a tension spring. A sound-absorbing module 300 is threadedly connected to the air inlet end of the fan 700, and a noise-reducing module 400 is threadedly connected to the air outlet end. During installation, the third connecting seat 701 of the fan 700 is aligned with the bolt holes 213 of the mounting base 200, and the fan 700 is fixed with bolts. The fourth connecting seat 702 is connected to the tension spring 206. The sound-absorbing module 300 and the noise-reducing module 400 are respectively installed at the air inlet and air outlet ends of the fan 700. Through the vibration damping and fixing effect of the mounting base 200, and the noise reduction effect of the sound-absorbing module 300 and the noise-reducing module 400, the noise generated by the fan 700 during operation is effectively reduced.

[0032] The above embodiments disclose a detachable noise reduction structure and an air-cooled device containing the structure. During installation, the fan 700 is placed in the semi-circular mounting groove 204, and then the tension spring 206 is connected to the fourth connecting seat 702 at the lower end of the fan 700. Next, the two movable seats 202 are closed so that the quarter-circular mounting groove 208 is locked at the upper end of the fan 700, and the connecting block 212 is fixed by bolt connection. Then, the fourth connecting seats 702 at both ends of the fan 700 are bolted to the bolt holes 213 at both ends of the mounting seat 200. Then, the electric telescopic rod 210 is controlled to extend, driving the arc-shaped pressure plate 211 to press the air-cooled device. Then, the sound-absorbing module 300 and the noise-absorbing module 400 are respectively installed at the air inlet and air outlet of the fan 700. Through the shock absorption and fixing effect of the mounting seat 200, and the noise reduction effect of the sound-absorbing module 300 and the noise-absorbing module 400, the noise generated by the fan 700 during operation is effectively reduced.

[0033] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
