Description

Technical Field

[0001] This utility model belongs to the field of server technology, and more specifically, it relates to a server heat dissipation filter structure. Background Technology

[0002] Servers generate a significant amount of heat during operation. If this heat cannot be dissipated effectively and promptly, it can lead to decreased server performance, shortened lifespan, and even malfunctions. To ensure long-term normal operation, servers are typically equipped with cooling filters to effectively dissipate heat from the internal components. These filters also prevent external dust from entering the server during the cooling process. However, traditional server cooling filters are often statically mounted, which allows dust to accumulate. Over time, the filter's pores become clogged, significantly reducing airflow and hindering the entry of cool air for heat exchange. This results in heat buildup inside the server, severely impacting cooling efficiency, causing the server to operate at high temperatures for extended periods, accelerating hardware aging, and reducing server stability and lifespan. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a server heat dissipation filter structure to solve the technical problem in the prior art where traditional static filters cause dust accumulation that clogs ventilation holes, reduces ventilation, affects heat dissipation, and leads to high-temperature operation of the server.

[0004] The purpose and effect of this utility model's server heat dissipation filter structure are achieved by the following specific technical means:

[0005] A server heat dissipation filter structure includes a cabinet, on which a detachable back panel and a top panel are provided. The three are connected to form a main cavity. An air inlet duct is provided on the back panel, and multiple sets of air outlet ducts are provided on the top panel. The air inlet duct and the air outlet duct are both connected to the main cavity. The three are connected to form a heat dissipation path for dissipating heat from inside the server.

[0006] The air inlet duct is equipped with a filter assembly and multiple sets of air intake fans. The air intake fans are installed at one end of the air inlet duct near the cabinet and are used to blow the air filtered by the filter assembly into the main body cavity.

[0007] The filter assembly includes a filter screen, the top of which is rotatably connected to the air inlet duct via a rotating shaft, and the filter screen swings about the rotating shaft.

[0008] According to a preferred embodiment, a baffle is provided inside the air inlet duct, and an air inlet channel is formed between the baffle and the air inlet duct. The air inlet channel is divided into an air inlet end and an air outlet end. The height of the air inlet end is greater than the height of the air outlet end. The filter screen is located at the air inlet end. An installation plate is provided inside the air outlet end, and the air intake fan is installed on the installation plate.

[0009] Multiple sets of springs are installed between one side of the filter screen and the air inlet duct, and a retractable sealing curtain is installed between the other side of the filter screen and the baffle. The air inlet channel is divided into two spaces by the sealing curtain and the baffle, so that the air entering at the air inlet end must pass through the filter screen to enter the air outlet end.

[0010] According to a preferred embodiment, the filter assembly further includes a rotating rod, which is rotatably connected to the air inlet duct and located on one side of the filter screen, on the same side as the spring;

[0011] The rotating rod is provided with multiple sets of eccentric wheels, and the two ends of the eccentric wheels are protruding ends. When the protruding ends contact the filter screen, the filter screen swings towards the baffle, the spring stretches, and the sealing curtain retracts.

[0012] When the protruding end is not in contact with the filter screen, the spring returns to its original position, the filter screen returns to its original position due to the elasticity of the spring, and the sealing curtain stretches.

[0013] A motor is installed on one side of the air inlet duct, and the motor is connected to the rotating rod.

[0014] According to a preferred embodiment, a fixing groove is provided at the bottom of the air intake channel and on one side of the baffle. A dust collection component is installed in the fixing groove. The dust collection component is funnel-shaped. The two sets of dust collection components are connected to a dust collection fan through a connecting pipe.

[0015] The two sets of vacuum cleaners are located on both sides of the sealing curtain, respectively within the two spaces separated by the sealing curtain.

[0016] According to a preferred embodiment, the main body cavity is provided with multiple sets of exhaust fans, the exhaust fans are installed in the exhaust duct, and the exhaust duct is provided with two sets of exhaust ducts at one end above the top plate, and the air outlet is connected to the exhaust duct.

[0017] The air outlet faces the outside of the cabinet, and the air inside the main cavity is exhausted to the outside through the air outlet duct and the air outlet.

[0018] According to a preferred embodiment, one end of the air outlet is configured as a downward inclined surface, the angle between the inclined surface and the top surface of the air outlet is 50°, and a silicone plate is provided on the opening surface of the air outlet. The silicone plate is connected to the top of the air outlet and covers the inclined surface.

[0019] The air outlet is also equipped with a dustproof net.

[0020] According to a preferred embodiment, a protective plate is provided on one side of the cabinet, the protective plate is installed at one end of the air inlet duct, an electrostatic adsorption plate is provided on the protective plate, and ventilation slots are provided on both the protective plate and the electrostatic adsorption plate, through which air enters the air inlet duct.

[0021] An electrostatic generator is installed on one side of the air inlet duct, and the electrostatic generator is connected to the electrostatic adsorption plate.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. Inside the air intake duct, the top of the filter screen is rotatably connected to the duct via a rotating shaft, allowing it to swing around this shaft. A baffle is installed inside the duct to form an air intake channel, with the intake end higher than the outlet end. The filter screen is located at the intake end, with a spring on one side connecting it to the duct and a retractable sealing curtain on the other side connecting it to the baffle, dividing the air intake channel into two spaces. Simultaneously, an eccentric wheel on the rotating rod, driven by a motor, causes the filter screen to swing periodically, with the spring and sealing curtain moving in coordination. This design prevents the filter screen from being statically fixed; during air intake, the oscillation of the filter screen shakes off some dust, preventing dust accumulation and clogging of the ventilation holes. This significantly increases ventilation, ensuring that cool air can fully enter the server for heat exchange, preventing heat buildup inside the server, significantly improving heat dissipation, and ensuring the server operates stably at a suitable temperature.

[0024] 2. A funnel-shaped dust collector, located at the bottom of the air intake channel and on one side of the baffle, is connected to a dust extraction fan via a connecting pipe and situated in the spaces on both sides of the sealed curtain. This effectively removes dust shaken off the filter, further reducing dust residue on the filter. Multiple exhaust fans within the main body cavity, working in conjunction with the exhaust ducts and vents on the top panel, efficiently expel hot air from inside the server. The exhaust vents are tilted downwards at 50° and equipped with silicone mats and dust filters, preventing backflow of rainwater and debris while further filtering out airborne dust. An electrostatic adsorption plate on the protective panel on one side of the cabinet, activated by an electrostatic generator, adsorbs airborne dust, further optimizing the air quality entering the server. This comprehensive approach ensures excellent heat dissipation and a superior operating environment for the server, extending its lifespan. Attached Figure Description

[0033] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0034] Example:

[0035] like Figures 1 to 6As shown, this utility model provides a server heat dissipation filter structure, including a cabinet 11. The cabinet 11 serves as the basic support for the entire server heat dissipation filter structure, providing installation and housing space for other components, ensuring orderly assembly and stable operation of each component. The cabinet 11 is equipped with a detachable back panel 21 and a top panel 31. After the back panel 21 and top panel 31 are connected to the cabinet 11, the three together form a main cavity. The main cavity is used to house servers and other equipment, serving as the space for server operation and air circulation for heat dissipation. An air inlet duct 22 is provided on the back panel 21, guiding outside air into the main cavity to provide a source of cool air for server heat dissipation. Multiple sets of air outlet ducts 32 are provided on the top panel 31, expelling hot air absorbed by the server from the main cavity. Both the air inlet ducts 22 and the air outlet ducts 32 are connected to the main cavity, forming a heat dissipation path for expelling heat from inside the server, achieving air circulation within the server, carrying away the heat generated during server operation, and maintaining a suitable operating temperature for the server.

[0036] The air intake duct 22 is equipped with a filter assembly and multiple intake fans 23. The filter assembly is responsible for filtering the incoming air to prevent dust and other impurities from entering the main body cavity and affecting the normal operation of the server. The intake fans 23 are installed at the end of the air intake duct 22 near the cabinet 11. Their function is to generate suction to blow the air filtered by the filter assembly into the main body cavity, promote airflow in the heat dissipation path, and accelerate heat dissipation efficiency.

[0037] The filter assembly includes a filter screen 24, the top of which is rotatably connected to the air inlet duct 22 via a rotating shaft 25, allowing the filter screen 24 to swing around the rotating shaft 25. This connection method makes the filter screen 24 movable; when air flows through, the swinging of the filter screen 24 can shake off some dust, preventing dust from continuously accumulating on the filter screen and clogging the ventilation holes, thereby maintaining good ventilation and ensuring sufficient cool air enters the main cavity for heat exchange with the server.

[0038] like Figures 2 to 5 As shown, a baffle 26 is installed inside the air inlet duct 22, and the baffle 26 cooperates with the air inlet duct 22 to form an air inlet channel. The air inlet channel is divided into an air inlet end and an air outlet end, with the height of the air inlet end being greater than that of the air outlet end. This structure creates a certain pressure difference when the air flows within the air inlet channel, which helps the air to flow more smoothly. The filter screen 24 is located at the air inlet end, and can filter the air as soon as it enters the air inlet channel. A mounting plate 27 is installed inside the air outlet end, and the intake fan 23 is mounted on the mounting plate 27. The mounting plate 27 provides a fixed position for the intake fan 23, ensuring that the intake fan 23 operates stably.

[0039] Multiple springs are installed between one side of the filter screen 24 and the air inlet duct 22, providing elastic support and resetting. A retractable sealing curtain 28 is installed between the other side of the filter screen 24 and the baffle 26. The sealing curtain 28 and the baffle 26 divide the air inlet channel into two spaces, ensuring that air entering at the inlet must pass through the filter screen 24 before reaching the outlet. This design guarantees that air can only be filtered by the filter screen 24 before entering subsequent channels. Simultaneously, the sealing curtain 28 can extend and retract with the swing of the filter screen 24, maintaining the relative independence of the two spaces within the air inlet channel during the swing of the filter screen 24, preventing unfiltered air from bypassing.

[0040] The filter assembly also includes a rotating rod 41, which is rotatably connected to the air inlet duct 22 and located on one side of the filter screen 24, on the same side as the spring. Multiple eccentric wheels 42 are mounted on the rotating rod 41, with protruding ends at both ends. When the eccentric wheels 42 rotate with the rotating rod 41, their protruding ends contact the filter screen 24, pushing it to swing towards the baffle 26. At this time, the spring stretches, and the sealing curtain 28 retracts. When the protruding ends are not in contact with the filter screen 24, the spring returns to its original position, and the filter screen 24 returns to its original position due to the spring's elasticity, while the sealing curtain 28 stretches. In this way, the eccentric wheels 42 periodically cause the filter screen 24 to swing when the motor drives the rotating rod 41 to rotate, enhancing the dust removal effect. A motor is located on one side of the air inlet duct 22, connected to the rotating rod 41. The motor provides power for the rotation of the rotating rod 41, thereby controlling the swing of the filter screen 24.

[0041] Both the bottom of the air inlet duct 22 and one side of the baffle 26 have fixing grooves, and dust collection components 43 are installed in the fixing grooves. The dust collection components 43 are funnel-shaped, which facilitates dust collection. The two sets of dust collection components 43 are connected to a vacuum fan through connecting pipes. The vacuum fan generates suction to suck away the dust collected by the dust collection components 43. The two sets of dust collection components 43 are located on both sides of the sealing curtain 28, respectively in the two spaces separated by the sealing curtain 28. They can promptly remove the dust shaken off the filter screen 24, further reducing dust residue on the filter screen and maintaining the filtration effect of the filter screen 24.

[0042] like Figure 2 , Figure 6 As shown, multiple sets of exhaust fans 33 are installed inside the main body cavity. These fans 33 are mounted within the exhaust duct 32. The function of the exhaust fans 33 is to generate thrust, rapidly pushing the hot air inside the main body cavity towards the exhaust duct 32, accelerating the exhaust of the hot air. Two sets of air outlets 34 are located at one end of the exhaust duct 32 above the top plate 31. The air outlets 34 are connected to the exhaust duct 32, exhausting the hot air inside the exhaust duct 32 to the outside of the main body cavity. The air outlets 34 face outwards from the cabinet 11, allowing the air inside the main body cavity to be exhausted to the outside through the exhaust duct 32 and the air outlets 34, completing the circulation of cooling air.

[0043] One end of the air outlet 34 is designed with a downward-sloping surface, and the angle between the sloped surface and the top surface of the air outlet 34 is 50°. This sloped design prevents rainwater and debris from entering the main body cavity through the air outlet 34 and damaging the server. A silicone plate 35 is provided on the opening surface of the air outlet 34. The silicone plate 35 is connected to the top of the air outlet 34 and covers the sloped surface. The silicone plate 35 further blocks rainwater and debris from entering, and at the same time, it buffers the airflow speed to a certain extent and reduces noise. A dust filter 36 is also provided inside the air outlet 34. The dust filter 36 can perform secondary filtration of the exhaust air to prevent dust and other impurities carried in the exhaust air from re-entering the server's surrounding environment.

[0044] like Figure 2 As shown, a protective plate 12 is installed on one side of the cabinet 11. The protective plate 12 is installed at one end of the air intake duct 22, protecting the air intake duct 22 from collisions with external objects. An electrostatic adsorption plate 13 is installed on the protective plate 12. Both the protective plate 12 and the electrostatic adsorption plate 13 have ventilation slots 14, through which air enters the air intake duct 22. The ventilation slots 14 ensure that air can smoothly pass through the protective plate 12 and the electrostatic adsorption plate 13 into the air intake duct 22. Under the action of the electrostatic generator 15, the electrostatic adsorption plate 13 can adsorb dust in the air, further optimizing the air quality entering the server. An electrostatic generator 15 is installed on one side of the air intake duct 22, connected to the electrostatic adsorption plate 13, providing static electricity to the electrostatic adsorption plate 13, enabling it to adsorb dust. The electrostatic generator 15 can be a FRAS-20K electrostatic generator.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
