Description

Technical Field

[0001] This utility model relates to the field of cabinet technology, and in particular to an air guide structure and cabinet. Background Technology

[0002] Server racks are used to install equipment and are equipped with air inlets. Air enters through these inlets, and the cooled air is used to cool the interior of the rack. Some high-end equipment on the market has high requirements for the environment inside the rack, so air filtration systems are installed at the air inlets. These air filters need to be cleaned after prolonged use. However, most server racks on the market only allow for simple filter removal and cleaning, without cleaning the air guides or other components. This results in poor cleaning quality of the air inlets and inconvenient disassembly and maintenance.

[0031] This application provides an air guiding structure, including a cabinet door 11 with ventilation holes 12. The structure is characterized by an air guiding device 2 located inside the ventilation holes 12. This air guiding device 2 includes a mounting frame 221, air guide plates 210, and a filter element 217. A first fastener 220 detachably mounts the mounting frame 221 onto the cabinet door 11. A plurality of air guide plates 210 are obliquely arranged within the mounting frame 221. A first mounting groove 224 is provided at the bottom of the mounting frame 221, and a first mounting plate 226 is provided at the top of the mounting frame 221. The bottom of the filter element 217 is inserted into the first mounting groove 224, and the first mounting plate 226 presses down on the top of the filter element 217. The ventilation holes 12 are a plurality of holes arranged in a matrix on the cabinet door 11. The first fastener 220 is preferably a spring screw or a screw; in this embodiment, the first fastener 220 is a spring screw. The first fastener 220 secures the mounting frame 221 to the cabinet door 11. To remove the air guide device 2, simply loosen the first fastener 220. When removing the filter element 217, loosen the first mounting plate 226 and then pull the filter element 217 out of the first mounting groove 224. Therefore, the entire air guide device 2 is detachable and can be cleaned separately, resulting in better cleaning quality and convenient maintenance.

[0032] Preferably, the upper edge of the air guide plate 210 is bent to form a first baffle 211, which is blocked by the mounting frame 221; the lower edge of the air guide plate 210 is bent to form a second baffle 212, which has several notches 213; the second baffle 212 is blocked by the cabinet door 11. The first baffle 211 has an L-shaped structure, and the second baffle 212 has a straight plate structure. The corresponding shapes of the first baffle 211 and the second baffle 212 can position the air guide plate 210, prevent it from rotating, and improve the stability of the installation. In addition, the L-shaped structure of the first baffle 211 can slightly reduce the wind speed, which helps to reduce wind noise. At the same time, the several notches 213 on the second baffle facilitate air inflow and also reduce the noise generated by the air being cut by the second baffle 212. That is, the shapes of the first baffle 211 and the second baffle 212 not only fix the air guide plate 210, but also greatly reduce wind noise.

[0033] Preferably, the left and right edges of the air guide plate 210 are bent to form a second mounting plate 215; the mounting member 214 passes through the second mounting plate 215 and the mounting frame 221. The mounting member 214 is preferably a screw or rivet. The mounting member 214 installs the air guide plate 210 in the mounting frame 221, which is very convenient and has a simple structure.

[0034] Preferably, a first spring screw 225 passes through the first mounting plate 226, and the first spring screw 225 fixes the first mounting plate 226 to the mounting frame 221. Loosening the first spring screw 225 allows the first mounting plate 226 to release the filter element 217. At this time, the filter element 217 can be pulled out from the first mounting groove 224, and then the filter element 217 can be cleaned.

[0035] Preferably, the mounting frame 221 has mounting edges 222 formed by bending around its perimeter; the second spring screw 223 passes through the mounting edges 222 and fixes the mounting frame 221 to the cabinet door 11. The mounting frame 221 can be formed by stamping or by welding. Tightening the second spring screw 223 can fix the mounting frame 221 to the cabinet door 11, and untightening it can remove the mounting frame 221 from the cabinet door 11, which is very convenient.

[0036] Preferably, the air guiding device 2 further includes an electrostatic dust removal grille 216; the bottom of the electrostatic dust removal grille 216 is inserted into the first mounting groove 224, and the filter element 217 is pressed onto the electrostatic dust removal grille 216. The electrostatic dust removal grille 216 is a device that uses the principle of electrostatics for dust removal. It uses an electric field to adsorb airborne particles onto electrodes, and then removes the particles through a dust removal system, thereby achieving air purification. The electrostatic dust removal grille 216 can adsorb dust particles in the air, and this design can improve the service life of the filter element 217. The electrostatic dust removal grille 216 is also detachable. Simply disconnect the power supply, loosen the first mounting plate 226, and then pull the filter element 217 out of the first mounting groove 224.

[0037] Preferably, the filter element 217 includes a filter screen 218 and a filter element 217 body arranged sequentially from the outside to the inside; the filter element 217 body is pressed onto the filter screen 218. The filter screen 218 can be a plastic filter screen 218, a cotton filter screen 218, a composite filter screen 218, an activated carbon filter screen 218, etc. The filter element 217 can be a sponge, a cotton filter element 217, an activated carbon filter element 217, a HEPA filter element 217, etc. Both the filter screen 218 and the filter element 217 body can be replaced separately, which helps to reduce costs.

[0038] Preferably, a sealing groove is pressed into the inner side of the cabinet door 11, and a sealing ring is provided in the sealing groove; the mounting frame 221 presses on the sealing ring. The sealing groove is formed by stamping on the cabinet door 11. The mounting frame 221 presses on the sealing ring. This design can improve the sealing degree, and air can only enter the cabinet 1 through the air guide plate 210.

[0039] The tilt angle A of the air guide plate 210 is between 30° and 60°, for example, one of 30°, 45°, 50°, or 60°. This design can reduce wind noise and improve quietness.

[0040] Example 2

[0041] This application provides a server rack 1, including the aforementioned air guide structure; the server rack 1 includes a main body 10 and a cabinet door 11 that can be opened and closed on the main body 10; a plurality of cooling fans 13 are provided on the side of the main body 10. When the cooling fans 13 draw hot air out of the server rack 1, cool air from outside enters the server rack 1 through the air guide structure. This type of server rack 1 has good noise reduction and is easy to clean and maintain. Furthermore, cooling fans are provided on both sides, allowing air to be exhausted from both sides, resulting in good heat dissipation.

[0042] In summary, the key design feature of this utility model is that its air guide structure can be disassembled from the cabinet door 11, and the filter element 217 can be disassembled from the mounting frame 221. This design makes disassembly, maintenance, and cleaning convenient and results in better cleaning quality.
