Description

Technical Field

[0001] This invention relates to the field of ventilation window technology, and in particular to a noise-reducing ventilation window. Background Technology

[0002] In equipment enclosure applications such as communication cabinets, power supply rooms, and electrical control cabinets, ventilation windows are typically installed to ensure the heat dissipation of internal electrical components. Traditional ventilation windows primarily function as ventilation, heat dissipation, dustproofing, and waterproofing, and often employ perforated, louvered, or filter-type structures, with airflow channels directly connecting the inside and outside.

[0003] While such structures can meet the equipment's heat dissipation and protection requirements, they lack sound insulation and noise reduction structures, failing to effectively block electromagnetic noise and fan noise generated by internal equipment operation. This easily leads to noise diffusion outwards, affecting the surrounding environment and personnel's work. Furthermore, existing ventilation windows generally suffer from a trade-off between ventilation protection and sound insulation, making it difficult to achieve effective noise reduction while ensuring protection. This fails to meet the dual requirements of low noise and high protection for equipment such as server racks and electrical rooms. Summary of the Invention

[0022] The following is for reference. Figures 1 to 10 A noise-reducing ventilation window according to an embodiment of the present invention is described.

[0023] like Figures 1 to 10 As shown, the noise-reducing ventilation window according to an embodiment of the present invention includes a protective window body 100 and a noise-reducing window assembly. The protective window body 100 includes a protective window frame 110 and a protective blade assembly 120 disposed within the protective window frame 110. The noise-reducing window assembly is disposed behind the protective window body 100. The noise-reducing window assembly includes at least one noise-reducing window body 200. The noise-reducing window body 200 includes a noise-reducing window frame 210 and a noise-reducing blade assembly 220 disposed within the noise-reducing window frame 210. The noise-reducing blade assembly 220 includes a plurality of noise-reducing blades 300 spaced apart in the vertical direction. The noise-reducing blades 300 include a blade outer frame 310 and a sound-absorbing medium 320. A sound-absorbing cavity is disposed inside the blade outer frame 310, and the sound-absorbing medium 320 is disposed inside the sound-absorbing cavity. The blade outer frame 310 is provided with a first connecting hole 311 communicating with the sound-absorbing cavity.

[0024] The ventilation and protection effect is achieved by the protective window 100 located on the front side. When the noise emitted by the equipment inside the ventilation window is transmitted through the ventilation window, the noise enters the silencing cavity through the first connecting hole 311 and is absorbed or weakened by the silencing medium 320, thereby reducing the noise transmitted through the ventilation window and achieving the noise reduction effect.

[0025] In some embodiments of the present invention, the sound-absorbing medium 320 is a porous sound-absorbing medium such as rock wool, polyester fiber sound-absorbing cotton, melamine foam, felt, non-woven fabric or porous ceramic.

[0026] In some embodiments of the present invention, the inner wall of the silencing cavity is provided with a silencing layer to further improve the silencing effect.

[0027] In some embodiments of the present invention, the sound-absorbing layer can be formed by attaching sound-absorbing fleece or applying a sound-absorbing coating.

[0028] In some embodiments of the present invention, the first connecting hole 311 is opened on the inner side of the noise reduction blade 300 facing the noise reduction ventilation window (either facing forward or at an angle), so that the noise emitted by the equipment inside the ventilation window can directly enter the silencing cavity through the first connecting hole 311 for silencing treatment, thereby achieving a better noise reduction effect.

[0029] like Figure 8 , Figure 9 As shown, in some embodiments of the present invention, the blade outer frame 310 includes a profile 330 and a cover plate 340. The profile 330 is an elongated structure and has an inner cavity 331 extending along its length. The inner cavity 331 has an opening. The cover plate 340 is detachably mounted on the opening to form a sound-absorbing cavity in the inner cavity 331. A first connecting hole 311 is provided on the cover plate 340. The profile 330 is easy to manufacture and can be directly mass-produced and cut by processes such as extrusion molding. The first connecting hole 311 on the cover plate 340 can be formed by machining or stamping. After the sound-absorbing medium 320 is filled into the profile 330 and the cover plate 340 is installed, a blade with noise reduction function can be obtained. The manufacturing process is convenient and the cost is low.

[0030] In some embodiments of the present invention, the profile 330 can be an aluminum profile, which can be quickly produced by extrusion molding, and the cover plate 340 is a metal plate, which can be quickly produced by stamping or machining. Both have low production costs, thereby reducing the overall manufacturing cost of the noise reduction ventilation window.

[0031] In some embodiments of the present invention, the cover plate 340 is inclined relative to the air inlet and outlet direction. Of course, in specific implementation, the cover plate 340 can also be set perpendicular to the air inlet and outlet direction, both of which can achieve a good noise reduction effect.

[0032] like Figure 10 As shown, in some embodiments of the present invention, the blade outer frame 310 has a parallelogram cross section, and the cover plate 340 is obliquely upward along the air outlet direction of the ventilation window, which can not only form a protective air duct and meet the effect of ventilation and protection, but also achieve a good noise reduction effect.

[0033] In some embodiments of the present invention, the profile 330 is provided with a second connecting hole 312 that connects to the silencing cavity, so as to further expand the connection between the silencing cavity and the outside and improve the noise reduction effect.

[0034] like Figure 8 and Figure 9As shown, in some embodiments of the present invention, the blade outer frame 310 has a parallelogram cross section, and the second connecting hole 312 is disposed on the vertical surface of the profile 330 facing the noise reduction ventilation window.

[0035] It is understood that in some embodiments of the present invention, the second connecting hole 312 may also be provided on the inclined surface of the blade outer frame 310, which will not be described in detail here.

[0036] like Figure 9 As shown, in some embodiments of the present invention, the edge of the opening is provided with an insertion groove 332 corresponding to the edge of the cover plate 340. The cover plate 340 can be inserted into the profile part 330 along the insertion groove 332, which is convenient and quick to install. Moreover, the insertion groove 332 can be directly formed when the profile part 330 is formed, which is simple in production process and low in cost.

[0037] It is understood that, in some embodiments of the present invention, the cover plate 340 may also be installed to the profile part 330 by means of a snap-fit ​​mechanism, a screw mechanism, etc.

[0038] like Figure 3 , Figure 4 , Figure 5 , Figure 8 and Figure 9 As shown, in some embodiments of the present invention, mounting members 350 are respectively provided at both ends of the noise reduction blade 300. The mounting member 350 extends upward or downward and is provided with a spacing portion 351. The noise reduction window frame 210 is provided with a mounting groove 201 corresponding to the mounting member 350. Multiple noise reduction blades 300 can be slidably installed into the noise reduction window frame 210 in the vertical direction through the sliding cooperation between the mounting member 350 and the mounting groove 201. And adjacent noise reduction blades 300 can form a gap through the spacing portion 351. Multiple noise reduction blades 300 can be installed into the noise reduction window frame 210 at intervals in the vertical direction, which is convenient and quick to assemble.

[0039] like Figure 3 , Figure 4 , Figure 5 As shown, in some embodiments of the present invention, the noise-reducing window frame 210 is a square structure assembled from four frame strips, with a mounting groove 201 formed in the middle of the frame strips. During assembly, the noise-reducing window frame 210 is first initially assembled into a U-shaped structure. The noise-reducing blades 300 can be sequentially inserted into the noise-reducing window frame 210 from top to bottom through the cooperation of the mounting parts 350 and the mounting grooves 201 of the left and right frame strips. Finally, the upper frame strip is sealed to complete the assembly of the noise-reducing window 200.

[0040] In some embodiments of the present invention, the mounting member 350 is provided with an insertion position for inserting the end of the noise reduction blade 300, that is, the end of the noise reduction blade 300 is inserted into the mounting member 350, which makes assembly convenient and quick.

[0041] It is understood that, in some embodiments of the present invention, the noise-reducing blade 300 may also be installed to the noise-reducing window frame 210 by other means, such as by a clip-on mechanism, a screw fixing mechanism, etc.

[0042] like Figure 6 As shown, in some embodiments of the present invention, the noise reduction window group includes two sets of noise reduction windows 200 distributed along the front-back direction, the noise reduction blades 300 have a parallelogram cross-section, and the noise reduction blades 300 of the two sets of noise reduction windows 200 are distributed in a V-shape to form an inverted V-shaped air channel, thereby achieving better ventilation, protection and noise reduction effects.

The noise reduction blades 300 of the two sets of noise reduction window bodies 200 are staggered along the air inlet and outlet directions, so that the air and noise propagation paths are diverted multiple times, achieving better ventilation, protection and noise reduction effects.

[0044] like Figure 5 , Figure 6 As shown, in some embodiments of the present invention, the noise reduction window assembly includes at least two sets of noise reduction window bodies 200. The rear side of the noise reduction window frame 210 is provided with annularly distributed protrusions 211, and the front side of the noise reduction window frame 210 is provided with recesses 212 corresponding to the protrusions 211. The protrusions 211 of the front noise reduction window frame 210 can be inserted into the recesses 212 of the rear noise reduction window frame 210 to connect adjacent noise reduction window bodies 200, so that multiple noise reduction window bodies 200 can be assembled and combined in a front-to-back layout, thereby satisfying the modular combination of window bodies, meeting different noise reduction and protection requirements, having high flexibility of use, and facilitating the production of different types of noise reduction ventilation windows.

[0045] In some embodiments of the present invention, adjacent noise-reducing window frames 210 can be connected by rivets, screws, clips or other mechanisms to improve the overall stability and reliability of the noise-reducing ventilation window.

[0046] like Figure 6 As shown, in some embodiments of the present invention, the noise-reducing ventilation window further includes a filter assembly 400, and the inner side of the protrusion 211 forms a stepped structure 213 that allows the filter assembly 400 to be installed, so as to facilitate the installation of the filter assembly 400 and improve the dustproof effect.

[0047] Specifically, the filter assembly 400 is configured as a square plate structure, and the stepped structure 213 forms a square groove corresponding to the filter assembly 400 on the rear side of the noise reduction window frame 210. The filter assembly 4000 can be placed into the square groove and limited in the square groove by a limiting mechanism such as a limiting member or screw.

[0048] like Figure 6 As shown, in some embodiments of the present invention, a protruding structure 111 corresponding to the recessed portion 212 is provided on the rear side of the protective window frame 110. The protruding structure 111 can be inserted into the recessed portion 212 of the noise-reducing window 200 located on the rear side of the protective window frame 110 to connect the protective window frame 110 and the noise-reducing window 200, so as to facilitate the assembly of the protective window frame 110 and the noise-reducing window 200.

[0049] Specifically, the connection stability between the protective window frame 110 and the noise reduction window 200 can be enhanced through screw mounting mechanisms, riveting mechanisms, etc.

[0050] In some embodiments of the present invention, the blade cross-section of the protective blade assembly 120 is V-shaped, W-shaped or U-shaped, and various blade combinations can be used to achieve different protection requirements.
