Description

Technical Field

[0001] This utility model relates to the field of blade server technology, specifically a shielding and anti-interference mechanism suitable for blade servers. Background Technology

[0002] A blade server is a compact server that integrates multiple server blades in a standard rack. Each blade has an independent processor, memory, storage, and network adapter, sharing the same infrastructure for easy centralized management. It offers high density and is suitable for data center environments, reducing space footprint and power consumption.

[0003] Electromagnetic interference (EMI) is a type of energy generated by electromagnetic fields that can affect the normal operation of electronic devices. When blade servers are installed inside racks, there are often many electrical devices in a typical data center that generate a lot of electromagnetic fields. In order to reduce the impact of EMI on the blade server components, shielding and anti-interference mechanisms are needed to provide external EMI protection for the blade servers installed inside the racks.

[0004] However, when using shielding and anti-interference mechanisms for blade servers to provide external electromagnetic interference protection, the ventilation inside the anti-interference components can easily bring external dust and foreign objects into the anti-interference mechanism, causing a large amount of dust to accumulate inside the blade server. This reduces the blade server's fault filtration capability and is therefore insufficient. It does not have the ability to simultaneously provide ventilation and dust prevention within the shielding and anti-interference structure.

[0005] Now, a novel shielding and anti-interference mechanism suitable for blade servers is proposed to address the above-mentioned shortcomings. Utility Model Content

[0006] The purpose of this invention is to provide a shielding and anti-interference mechanism suitable for blade servers, so as to solve the problem mentioned in the background art that it is inconvenient to ventilate the interior of the shielding and anti-interference structure while preventing dust.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a shielding and anti-interference mechanism suitable for blade servers, including a shielding cover, an exhaust fan fixedly installed at the top of the shielding cover, grooves respectively opened at the top and bottom of the rear end of the shielding cover, and an air inlet hole opened at the front end of the groove, a metal filter screen is provided inside the groove, and magnetic strips are fixed at the top, bottom and sides of the front end of the metal filter screen.

[0008] Preferably, three sets of magnetic strips are provided at equal intervals at the top and bottom of the rear end of the shield.

[0009] Preferably, six sets of air inlets are equally spaced at the front end inside the groove, and the air inlets penetrate the interior of the rear end of the shield and are connected to the interior of the shield.

[0010] Preferably, storage boxes are symmetrically arranged at the bottom of both sides inside the shield, and a plug is fixed on the right side of the storage box. Slots are respectively opened at the bottom of both sides inside the shield. A cover plate is provided at the top of the storage box. Activated carbon particles are filled inside the storage box. Through holes are respectively opened inside the two sides of the storage box.

[0011] Preferably, the through holes penetrate the interior of both sides of the storage box, and multiple sets of through holes are equally spaced inside both sides of the shielding cover.

[0012] Preferably, the cover plate has pins fixed at the four corners at the bottom, and the storage box has holes at the four corners at the top.

[0013] Preferably, the shielding cover is fixed with a mounting base on each side, and the left side of the mounting base has an internal mounting groove, and the mounting groove is hinged to a handle, which is symmetrically arranged about the vertical center line of the shielding cover.

[0014] Preferably, mounting side plates are welded and fixed to the bottom ends of both sides of the shielding cover, a door is provided at the front end of the shielding cover, a fixing frame is fixed to the top and bottom of the left front end of the shielding cover, a connecting foot is fixed to the top and bottom of the left side of the door, and the connecting foot is hinged to the inside of the fixing frame, a viewing window is fixed inside the door, a locking rod is provided to the top and bottom of the right front end of the door, a threaded hole is provided to the top and bottom of the right front end of the shielding cover, the rear end of the locking rod passes through the inside of the door and is rotatably connected to the inside of the threaded hole, and a wire groove is provided at the bottom of the rear end of the shielding cover.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the shielding and anti-interference mechanism suitable for blade servers not only facilitates ventilation and dust prevention inside the shielding and anti-interference structure, but also facilitates moisture protection inside the shielding and anti-interference structure, and makes it easy to move and relocate the shielding and anti-interference structure.

[0016] (1) By setting up a shield, air inlet, door, exhaust fan, metal filter, groove and magnetic strip, the shield is installed on the outside of the blade server. The metal shield can shield some external electromagnetic interference. During ventilation, the exhaust fan on the top of the shield can be started to draw in external air from the air inlet, which can assist the internal blade heat sink in ventilation and heat dissipation. At the same time, during ventilation, the metal filter is magnetically fixed in the groove at the rear end of the shield by magnetic strip. The metal filter can assist in filtering and removing some lint, dust and debris in the air drawn in from the air inlet, reducing the amount of dust and foreign objects entering the shield and anti-interference structure during ventilation. Ventilation and heat dissipation can also prevent dust.

[0017] (2) By setting up a shielding cover, slots, plugs, storage boxes, cover plates, activated carbon particles and through holes, the shielding and anti-interference structure is installed on the outside of the blade server. Storage boxes are inserted and installed at the bottom of both sides inside the shielding cover. The activated carbon particles loaded inside the storage boxes can communicate with the inside of the shielding cover through the through holes and can help adsorb the moisture in the air inside the shielding cover, dehumidify the air, maintain a dry environment inside the shielding and anti-interference structure, and reduce the moisture failure of the blade server inside the shielding and anti-interference structure.

[0018] (3) By providing a shielding cover, a fixed base, a mounting slot and a handle, the shielding anti-interference structure can be easily lifted and aligned by flipping the handles on both sides of the fixed base until they are perpendicular to the fixed base. The shielding anti-interference structure can then be easily moved and installed on the outside of the server by using the two sets of fixed bases. Attached Figure Description

[0027] Example 1: Please refer to Figure 1-6 A shielding and anti-interference mechanism suitable for blade servers includes a shielding cover 2, an exhaust fan 6 is installed and fixed at the top of the shielding cover 2, grooves 11 are respectively opened at the top and bottom of the rear end of the shielding cover 2, and an air inlet 4 is opened at the front end of the groove 11. A metal filter 12 is provided inside the groove 11, and magnetic strips 17 are respectively fixed at the top, bottom and sides of the front end of the metal filter 12.

[0028] The magnetic strips 17 are arranged in three sets at equal intervals at the top and bottom of the rear end of the shield 2, and the air inlet holes 4 are arranged in six sets at equal intervals at the front end inside the groove 11. The air inlet holes 4 penetrate through the interior of the rear end of the shield 2 and are connected to the interior of the shield 2.

[0029] Specifically, such as Figure 1 and Figure 2 As shown, after the shielding cover 2 is installed on the outside of the blade server, the metal shielding cover 2 can shield against some external electromagnetic interference. During ventilation, the exhaust fan 6 on the top of the shielding cover 2 can be started to draw in external air through the air inlet 4, which can provide auxiliary ventilation and heat dissipation for the internal blade heat sink. At the same time, during ventilation, a metal filter 12 is magnetically fixed inside the groove 11 at the rear end of the shielding cover 2 by magnetic strips 17. The metal filter 12 can help filter and remove some lint, dust and other debris in the air drawn in from the air inlet 4, reducing the amount of dust and foreign objects entering the shielding and anti-interference structure during ventilation.

Plugs are fixed at the four corners at the bottom of the cover plate 18. Plug holes are respectively opened inside the four corners at the top of the storage box 9.

[0031] Specifically, such as Figure 1 and Figure 3 As shown, storage boxes 9 are inserted and installed at the bottom of both sides inside the shielding cover 2. The activated carbon particles 19 loaded inside the storage box 9 can communicate with the inside of the shielding cover 2 through the through hole 20, and can assist in adsorbing the moisture in the air inside the shielding cover 2, dehumidifying the air, and maintaining a dry environment inside the shielding and anti-interference structure. This can reduce the moisture failure of the blade server inside the shielding and anti-interference structure. The activated carbon particles 19 can be replaced after pulling out the storage box 9 and opening the cover plate 18.

[0032] Example 3: Fixing bases 3 are fixed on both sides of the shielding cover 2, and the interior of the left side of the fixing base 3 is provided with a mounting groove 21, and a handle 22 is hinged to the interior of the mounting groove 21. The handle 22 is symmetrically arranged about the vertical center line of the shielding cover 2.

[0033] Specifically, such as Figure 1 and Figure 4 As shown, the handles 22 on both sides of the shielding cover 2 can be flipped upwards to be perpendicular to the fixed bases 3. The shielding anti-interference structure can be easily lifted and aligned and installed on the outside of the server through the two sets of fixed bases 3. The shielding anti-interference structure can be moved quickly.

[0034] The bottom ends of both sides of the shielding cover 2 are welded and fixed with mounting side plates 1. The front end of the shielding cover 2 is provided with a door body 14.

The bottom of the rear end of the shielding cover 2 is provided with a wire groove 10.

[0035] Working Principle: When in use, the shielding cover 2 is installed on the outside of the blade server. The metal shielding cover 2 can shield against external electromagnetic interference. During ventilation, the exhaust fan 6 on top of the shielding cover 2 can be activated to draw in external air through the air inlet 4, providing auxiliary ventilation and heat dissipation for the internal blade heat sink. Simultaneously, during ventilation, a metal filter 12 is magnetically fixed inside the groove 11 at the rear end of the shielding cover 2 via a magnetic strip 17. This metal filter 12 can auxiliaryly filter and remove lint, dust, and other debris from the air drawn in through the air inlet 4. This provides ventilation and heat dissipation while preventing dust and providing shielding against dryness. When the anti-interference structure is installed on the outside of the blade server, storage boxes 9 are inserted and installed at the bottom of both sides inside the shielding cover 2. The activated carbon particles 19 loaded inside the storage boxes 9 can communicate with the inside of the shielding cover 2 through the through holes 20, and can assist in adsorbing the moisture in the air inside the shielding cover 2, dehumidifying the air and maintaining a dry environment inside the shielding anti-interference structure. When using the shielding anti-interference structure, the handles 22 set in the fixing seats 3 on both sides of the shielding cover 2 can be flipped upwards until they are perpendicular to the fixing seats 3. The shielding anti-interference structure can then be easily lifted and aligned and installed on the outside of the server through the two sets of fixing seats 3.
