Description

Technical Field

[0001] This utility model relates to the field of server racks, and more particularly to ventilated and filtered server racks. Background Technology

[0002] The storage environment (operating and idle storage) of a server directly determines its stability, lifespan, and data security. The core requirements revolve around six dimensions: temperature and humidity, cleanliness, power supply, vibration and shock, electromagnetic interference, and space ventilation. However, hosting a server in a standard storage room is very expensive, so some small businesses put their servers in idle rooms. Current server racks are designed according to cleanroom standards and do not have the ability to filter dust. This means that storing servers in ordinary environments will cause a large amount of dust to accumulate on the surface and inside of the server, which is not conducive to the long-term preservation of the server. Summary of the Invention

[0003] To address the aforementioned issues, this utility model provides a ventilated and filtered server cabinet.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A ventilated and filtered server rack includes a rack body and a door hinged to the rack body for opening and closing. The rack body is a hollow rack body consisting of a top plate, a left side plate, a bottom plate, and a right side plate surrounding a back plate. The door is a rectangular frame, with an inward-facing filter cover mounting groove on the inner side of the outer frame of the door's outward-facing side for installing a filter cover. The rack body is characterized by further including a filter cover, a first filter plate, a second filter plate, a third filter plate, and a fan. An exhaust vent is located on the back plate of the rack body, with a partition covering the end of the exhaust vent. A fan is mounted on the partition and installed inside the exhaust vent. The filter cover is fixedly connected to the mounting groove. The filter cover is a rectangular box, and the size and shape of its outer ring match the size and shape of the inner ring of the mounting groove. Ventilation holes are located on the side of the filter cover away from the door body. The first filter plate is fixedly connected inside the filter cover, and the second and third filter plates are fixedly connected inside the door body. The shape and size of the third filter plate match the shape and size of the inner frame of the door body. When the fan is under negative pressure, the design allows air to pass through three layers of filter plates from the door into the cabinet and then be discharged from the exhaust vent. The filter plates ensure that the air entering the cabinet is clean air.

[0005] Furthermore, the first filter plate is made of spunbond polyester fiber (PET) nonwoven fabric or polypropylene (PP) spunbond nonwoven fabric to intercept large particulate impurities in the air and prevent them from clogging the subsequent second and third filter plates.

[0006] Furthermore, the second filter plate uses modified PP meltblown nonwoven fabric or coated glass fiber felt to capture medium-sized dust particles, further reducing the filtration load on the third filter plate.

[0007] Furthermore, the third filter plate uses PTFE (polytetrafluoroethylene) membrane filter material or nano-silica coated glass fiber filter paper to intercept fine dust and aerosols.

[0008] Furthermore, the ventilation and filtration server rack is also equipped with a locking device, which includes a locking groove and a locking buckle that cooperates with the locking groove. The locking groove is located on the outer wall of the left side panel of the rack near the opening, and the locking buckle is located on the outer wall of the left side frame of the door near the opening. The position of the locking buckle corresponds to the position of the locking groove. The locking groove has a rectangular groove, and the top surface of the locking groove has a locking groove hole that connects to the rectangular groove. The locking buckle has a ring buckle, the size and position of which are adapted to the rectangular groove. The ring buckle has a ring buckle hole that runs longitudinally through the ring buckle.

[0009] Furthermore, the fan includes an impeller and blades mounted on the side of the impeller. The impeller is a rearward impeller, and the blades are bent in the opposite direction to the rotation direction. The impeller is mounted on a partition plate, and the connection of the drive motor passes through an opening in the partition plate and is connected to the impeller. This design enables the fan to perform negative pressure ventilation.

[0010] Furthermore, the partition is a circular grid panel with several openings for ventilation. The size of the partition matches the size of the ventilation openings. This design allows the gas inside the cabinet to be discharged normally, thereby achieving gas circulation.

[0011] Furthermore, a sealing groove is provided on the opening surface of the cabinet, and the sealing groove is in close contact with the edges of the top panel, left side panel, bottom panel and right side panel of the cabinet; a sealing gasket is provided on the side of the door that closes with the opening surface of the cabinet, and the position, shape and height of the sealing gasket match the position, shape and depth of the sealing groove; this design seals the opening and closing of the cabinet and the door to prevent external gas from entering the cabinet from the opening and closing seam.

[0012] Furthermore, the bottom plate of the cabinet is equipped with wiring holes; this design is used to connect the server's connection cable to the outside world.
