Description

Technical Field

[0001] This invention relates to the field of cooling equipment technology, specifically to a sealed, self-cleaning server immersion liquid cooling device. Background Technology

[0002] Server immersion liquid cooling equipment mainly involves completely immersing the entire server motherboard and chip heat-generating components in a special thermally conductive but insulating coolant. Utilizing the liquid's thermal conductivity, which far exceeds that of air, it directly and efficiently removes the enormous heat generated during server operation. It is particularly suitable for high-density computing and artificial intelligence scenarios. It abandons traditional fans and heat sinks, directly immersing all the server's heat-generating components in a highly insulating and thermally conductive coolant. Through direct contact and flow between the liquid and the heat-generating surfaces, the heat is efficiently removed.

[0003] The installation sockets for server immersion liquid cooling equipment primarily supply power to the liquid cooling system itself and to the submerged equipment. When the plug is inserted and removed from the socket, dust particles are suspended in the surrounding air. Inserting and removing the plug compresses and draws air from the socket, creating a weak airflow. This airflow disturbs and carries away the dust particles accumulated on the surface of the socket, causing them to float and scatter near the socket. The airflow can easily carry dust particles into the socket, where they accumulate on the live metal parts. The accumulation of dust inside the socket increases contact resistance, causing overheating at the plug-socket connection. Dust accumulation can also lead to poor contact resistance and a fire risk. Summary of the Invention

[0004] The purpose of this invention is to provide a sealed, self-cleaning server immersion liquid cooling device to solve the problem mentioned in the background art that airflow disturbs and carries up dust particles accumulated on the surface of the socket, and the dust particles can then float near the socket. Airflow can easily carry dust particles into the socket and accumulate on the charged metal parts.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sealed, self-cleaning server immersion liquid cooling device, comprising;

[0006] The liquid cooling equipment enclosure has an internal cavity for placing the server;

[0007] The socket has a pre-drilled slot for the plug to be inserted into the socket.

[0008] A sliding electrostatic dust collection component is installed on the back of the liquid cooling equipment housing. It is used to generate electrostatic adsorption to attract dust particles near the sockets, thereby reducing the contact resistance of metal parts.

[0009] The unblocking extension component is located on one side of the sliding electrostatic dust collection component, and intermittently sucks in stationary dust particles as the sliding electrostatic dust collection component returns to its original position.

[0010] A rotating closure assembly, located inside the unblocking extension assembly, is used to adjust the passage area for dust particles to be drawn in by rotating.

[0011] The sliding electrostatic dust collection component and the unblocking extension component can pre-capture dust near the socket by electrostatic adsorption, making it easy for stationary dust to be collected intermittently through the unblocking extension component.

[0012] Preferably, the sliding electrostatic dust collection assembly further includes a package box, a servo motor, a first gear, a first straight rack, an extension rod, multiple package sleeves, multiple L-shaped plates, multiple arc plates, multiple vertical brush strips, multiple contact grooves, and multiple insulating rods.

[0013] Since the vertical brush bar is made of nylon and the inner wall of the contact groove is made of polyester, as the first gear rotates forward and backward, it drives the vertical brush bar to move back and forth repeatedly, thus rubbing against the contact groove repeatedly. During the friction process, the contact groove itself carries a strong negative charge, while the vertical brush bar carries a strong positive charge. The two generate static electricity through friction.

[0014] Preferably, the back of the liquid cooling equipment housing is provided with an abutment plate, and the interior of the abutment plate is provided with multiple socket components. The socket pre-reserved slots are used to receive the socket components. Insertion flat racks are provided on both sides of the multiple socket components. The package box is installed on the back of the abutment plate for the protection of the transmission structure.

[0015] The outer shell of the parcel box is made of aluminum alloy, which has a certain degree of hardness and can withstand external impacts, thus protecting the mechanical components inside.

[0016] Preferably, the transmission structure comprises a servo motor, a first gear, and a first straight rack. The servo motor is located inside the package box, and its output shaft is connected to one end of the first gear. The first gear meshes with the first straight rack to drive the extension rod to move left and right, causing the multiple vertical brush strips installed on both sides to repeatedly rub against the corresponding contact grooves to generate static electricity.

[0017] The vertical brush bar and the contact groove generate static electricity through friction. This static electricity can attract dust particles in the air around the insertion flattening frame to its surface, reducing the amount of dust spreading. Furthermore, the insertion flattening frame and multiple insulating rods are all made of insulating material, which can create a barrier between the socket and the vertical brush bar to prevent static electricity from affecting the current.

[0018] Preferably, the unblocking extension assembly further includes a mini vacuum cleaner, a vacuum head, a positioning disc, a hose, and a translation tube. The mini vacuum cleaner is located on one side of the package box and is electrically connected to an external power source via a plug. The hose is located between the mini vacuum cleaner and one of the package sleeves, and the package sleeve, L-shaped plate, arc plate, and vertical brush bar are interconnected. One end of the vertical brush bar has a round hole to provide a suction transmission space to accurately suck the clumps of dust particles into the dust collection chamber inside the mini vacuum cleaner.

[0019] Electrostatic adsorption ensures that the mini vacuum cleaner can not only suck up dust in a free state, but also pull out the dust that was originally stuck in the dead area before sucking it up.

[0020] Preferably, the rotary closing assembly further includes a displacement tube, a support rod, an extension plate, a second straight rack, a second gear, a closing disc, a through hole, a closing wheel, and a transmission bar.

[0021] With the support rod and extension plate connected, the second straight rack moves to the right, which in turn causes the second gear meshing with it to rotate counterclockwise.

[0022] Preferably, one end of the displacement tube is inserted and connected to one end of the translation tube to transmit the thrust to the second straight rack, which drives the second gear meshing with it to rotate, thereby adjusting the coverage area of ​​the closed wheel and the through hole.

[0023] As the second gear rotates, it drives the closing wheel to rotate clockwise. The bottom surface of the closing wheel gradually approaches the top of the through hole. When the two are in contact, the through hole is closed, and the air pressure of the mini vacuum cleaner will not continue to suck up dust through this position.

[0024] Preferably, after the second straight rack meshes with the second gear, it drives the closed wheel, which is fixedly sleeved at one end of the transmission bar, to rotate circumferentially. As the closed wheel rotates, the protruding part of the closed wheel fits against the surface of the closed disc and rotates. The closed wheel gradually covers the through hole. The opening and closing of the through hole allows the airflow of the suction head to be transmitted to multiple vertical brush bar ports through this part, which quickly sucks in the dust particles that have condensed near the ports, preventing the airflow from dispersing and feeding back to the dust particles and spreading.

[0025] By automatically adjusting the exposed area of ​​the through hole, the exposed area of ​​the through hole gradually increases, allowing the air pressure generated by the mini vacuum cleaner to be slowly transported through this part into the hose. This allows more air to be sucked in per unit time, thus enabling the rapid intake of a large amount of light, dispersed dust particles and preventing excessive suction from disrupting the airflow around the socket.

[0026] Preferably, the liquid cooling equipment housing has a liquid injection hole on the side of the outer shell, which allows coolant to be injected from the outside when necessary without opening the main cavity, forming a "bottom inlet, side replenishment" dual circuit with the bottom liquid supply. Electrochemical halogen sensors are installed at the four corners of the gap between the inner cavity and the outer shell of the liquid cooling equipment housing, and the electrochemical halogen sensors are linked to the alarm system.

[0027] When coolant leaks and vaporizes, the sensor can detect changes in halogen gas concentration and issue an alarm when the threshold is reached. The electrochemical halogen sensor is located between the inner cavity and the outer shell, which avoids direct contact between the electrochemical halogen sensor and the main coolant flow, thus improving the anti-interference capability of the liquid level sensor reading.

[0028] Preferably, the plurality of insulating rods are arranged at equal intervals on the inner surfaces of the plurality of inserting flattening frames.

[0029] The insulating rods are set up as a barrier, which physically isolates the electrostatically charged surface from the surrounding environment, cuts off any unintended current path, and ensures that the static charge is only used to attract dust and will not cause safety accidents.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] In this invention, a first straight rack, an extension rod, multiple wrapping sleeves, multiple L-shaped plates, multiple arc-shaped plates, multiple vertical brush bars, multiple contact grooves, and multiple insulating rods are used. With the start of the servo motor, its output shaft rotates in both directions, which in turn drives the first gear connected to it to rotate in both directions. When the first gear rotates forward, it drives the first straight rack, which meshes with it, to move. The first straight rack gradually extends from one side of the wrapping box. With the forward and reverse rotation of the first gear, it drives the vertical brush bars to move back and forth repeatedly, thus repeatedly rubbing against the contact grooves. During this friction process, the contact grooves themselves become strongly negatively charged, while the vertical brush bars become negatively charged. A strong positive charge is generated by friction between the two, which can attract dust particles in the air around the insert and flatten it to its surface, reducing the amount of dust. Before the plug is inserted into the socket, it can attract nearby dust particles, avoiding a large number of dust particles from fluctuating with the airflow when the plug is inserted into the socket. The hose is set between the mini vacuum cleaner and one of the sleeves, and the sleeve, L-shaped plate, arc plate and vertical brush bar are connected. One end of the vertical brush bar has a round hole to provide a space for the suction to accurately suck the clumps of dust particles into the dust collection chamber inside the mini vacuum cleaner.

[0032] In this invention, the displacement tube moves to the left via the second straight rack, the second gear, the closed disc, the through hole, the closed wheel, and the transmission bar. This causes the second straight rack connected to it to move to the left, and then drives the second gear, which meshes with it, to rotate clockwise. The closed wheel is fixedly sleeved on one end of the transmission bar, and the second gear is also fixedly sleeved on the other end of the transmission bar. As the second gear rotates, it drives the closed wheel to rotate clockwise. The bottom surface of the closed wheel gradually approaches the top of the through hole. As the closed wheel rotates, the protruding part of the closed wheel fits and rotates against the surface of the closed disc. The closed wheel gradually covers the through hole. The opening and closing of the through hole allows the airflow of the suction head to be transmitted to multiple vertical brush bar ports through this part, preventing the airflow from being dispersed and fed back to the dust particles, causing them to diffuse.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] To address the problem that existing sealed self-cleaning server immersion liquid cooling systems suffer from airflow disturbance during operation, which stirs up dust particles accumulated on the socket surface, causing these particles to float near the socket and easily enter the socket, accumulating on charged metal components, this invention provides a sealed self-cleaning server immersion liquid cooling system. (Refer to...) Figure 1 and Figure 2 As shown, it includes:

[0044] The liquid cooling equipment enclosure 100 has an internal cavity for placing the server;

[0045] The socket has a 300mm pre-drilled groove for the plug to be inserted into the socket.

[0046] A sliding electrostatic dust collection component 1 is installed on the back of the liquid cooling equipment housing 100 to attract dust particles near the sockets by generating electrostatic adsorption, thereby reducing the contact resistance of metal parts.

[0047] The unblocking extension component 2 is located on one side of the sliding electrostatic dust collection component 1, and intermittently sucks in stationary dust particles as the sliding electrostatic dust collection component 1 returns to its original position.

[0048] The rotating closure component 3, which is located inside the unblocking expansion component 2, is used to adjust the passage area when dust particles are sucked in by rotating.

[0049] The abutment plate 400 is fixed to the back of the liquid cooling equipment housing 100 by bolts. At this time, multiple socket pieces 411 are gradually inserted into the socket reserved slot 300. The inner surface of the socket reserved slot 300 is respectively attached to the outer wall of the socket piece 411 to ensure that there is no gap between them. The socket piece 411 mainly supplies power to the liquid cooling system itself and to the submerged equipment. Before the power plug is inserted into the socket hole opened on the surface of the socket piece 411, the liquid cooling equipment housing 100 is in a de-energized state. The servo motor 102 is started. The output shaft installed on the servo motor 102 rotates in the forward direction, driving the first gear 103 connected to its output shaft to rotate synchronously, and then driving the first straight rack 104 meshed with it to move. The first straight rack 104 gradually extends out from one side of the packaging box 101. With the connection of the extension rod 105, it drives multiple packaging sleeves 106. The L-shaped plate 107, the arc-shaped plate 108, and the vertical brush strips 109 move synchronously. At this time, the outer surfaces of the multiple vertical brush strips 109 rub against the inner wall of the contact groove 110. Since the vertical brush strips 109 are made of nylon and the inner wall of the contact groove 110 is made of polyester, the vertical brush strips 109 move back and forth repeatedly with the forward and reverse rotation of the first gear 103, thus repeatedly rubbing against the contact groove 110. During this friction, the contact groove 110 carries a strong negative charge, while the vertical brush strips 109 carry a strong positive charge. Static electricity is generated through friction. This static electricity can attract dust particles from the air surrounding the inserted flat support 511 to its surface, reducing the amount of dust. Furthermore, the inserted flat support 511 and the multiple insulating rods 111 are all made of insulating material, creating a barrier between the socket component 411 and the vertical brush strips 109 to prevent static electricity from affecting the current. (Reference) Figure 2 When the first straight rack 104 moves to the right, the extension rod 105 will also gradually move to the right, causing the displacement tube 301 inside the translation tube 205 to move to the right, which in turn drives the second straight rack 304 to move to the right, thereby causing the second gear 305 meshing with it to rotate counterclockwise. (Reference) Figure 8The diagram shows the state of the closed wheel 308 rotating counterclockwise. At this time, the through hole 307 is exposed. When the mini vacuum cleaner 201 is activated, a low-pressure zone is instantly created inside the mini vacuum cleaner 201 by the high-speed rotating fan inside. The normal atmospheric pressure outside will force the air and dust together to be "pressed" into the vacuum cleaner, thus achieving vacuuming. The exposed through hole 307 allows atmospheric pressure to be transmitted to the inside of the hose 204 through this part. Due to the wrapping sleeve 106, L-shaped plate 107, arc plate 108 and vertical The straight brush bar 109 is interconnected, and atmospheric pressure precisely sucks the clumps of dust particles into the dust collection chamber inside the mini vacuum cleaner 201. Electrostatic adsorption ensures that the mini vacuum cleaner 201 can not only suck up free dust, but also pull out the dust that was originally "adhered" to the dead area before sucking it up. At the same time, because the dust is pre-gathered, vacuuming does not require repeated back and forth cleaning, which greatly improves efficiency. It solves the problem that airflow can easily carry dust particles into the socket and accumulate on the charged metal parts, thus improving the safety of the liquid cooling equipment.

[0050] Preferred, according to Figure 1 As shown, the liquid cooling equipment housing 100 has a liquid injection hole on the side of the outer shell, which allows coolant to be injected from the outside when necessary without opening the main cavity, forming a "bottom inlet, side replenishment" dual circuit with the bottom liquid supply. Electrochemical halogen sensors 200 are installed at the four corners of the gap between the inner cavity and the outer shell of the liquid cooling equipment housing 100. The electrochemical halogen sensors 200 are linked with the alarm system. When the coolant leaks and vaporizes, they can detect the change in halogen gas concentration and issue an alarm when the threshold is reached.

[0051] The alarm system can detect abnormal halogen gas concentrations shortly after a coolant leak occurs and issue an alarm, enabling maintenance personnel to intervene in advance, shortening the response time to potential accidents, and preventing greater equipment damage and coolant loss.

[0052] The electrochemical halogen sensor 200 is positioned between the inner cavity and the outer shell, which avoids direct contact between the electrochemical halogen sensor 200 and the main coolant flow, thereby improving the anti-interference capability of the liquid level sensor reading and significantly reducing false alarms and monitoring failures caused by sensor malfunctions.

[0053] according to Figure 3 As shown, the sliding electrostatic dust collection assembly 1 also includes a package box 101, a servo motor 102, a first gear 103, a first straight rack 104, an extension rod 105, multiple package sleeves 106, multiple L-shaped plates 107, multiple arc-shaped plates 108, multiple vertical brush bars 109, multiple contact grooves 110, and multiple insulating rods 111.

[0054] The back of the liquid cooling equipment housing 100 is provided with an abutment plate 400. The abutment plate 400 has multiple socket pieces 411 inside. The socket reserved slot 300 is used to receive the socket pieces 411. Insertion flat racks 511 are provided on both sides of the multiple socket pieces 411. The package box 101 is installed on the back of the abutment plate 400 for the protection of the transmission structure.

[0055] The servo motor 102 is fixedly installed inside the package box 101. One end of the first gear 103 is connected to the output shaft of the servo motor 102. Translation slots are provided on both sides of the package box 101. The translation slots are used to hold the first straight rack 104 so that it can move smoothly. One side of the first straight rack 104 is fixedly connected to one end of the extension rod 105. Multiple package sleeves 106 are fixedly sleeved on one end of the extension rod 105. L-shaped plates 107 are fixedly inserted and connected to both sides of the multiple package sleeves 106. Arc plates 108 are inserted and connected to one side of the multiple L-shaped plates 107. Multiple vertical brush strips 109 are inserted and connected to one side of the multiple arc plates 108. Contact grooves 110 are provided on one side of the multiple insertion flattening frames 511. Multiple isolation insulating rods 111 are fixedly installed on one side of the multiple insertion flattening frames 511.

[0056] Preferably, the specific working process of the sliding electrostatic dust collection component 1 is as follows: Figure 4 As shown, the transmission structure consists of a servo motor 102, a first gear 103, and a first straight rack 104. The servo motor 102 is located inside the package box 101, and its output shaft is connected to one end of the first gear 103. The first gear 103 meshes with the first straight rack 104 to drive the extension rod 105 to move left and right, causing the multiple vertical brush strips 109 installed on both sides to repeatedly rub against the corresponding contact grooves 110 to generate static electricity.

[0057] The servo motor 102 and the first gear 103 are located inside the parcel box 101, preventing damage from external forces colliding with their surfaces, extending their service life, and reducing maintenance costs. When the servo motor 102 starts, it drives its output shaft to rotate in both directions, which in turn drives the connected first gear 103 to rotate in both directions. When the first gear 103 rotates forward, it drives the first straight rack 104, which meshes with it, to move. The first straight rack 104 gradually extends out from one side of the parcel box 101. (Refer to...) Figure 3The extension rod 105 moves to the left. Since the wrapping sleeve 106 is fixedly fitted to one end of the extension rod 105, it also moves to the left. With the connection of the L-shaped plate 107 and the arc-shaped plate 108, multiple vertical brush strips 109 can move to the left. These multiple vertical brush strips 109 sequentially rub against the inner surface of the contact groove 110 to the left. Because the vertical brush strips 109 are made of nylon and the inner wall of the contact groove 110 is made of polyester, the forward and reverse rotation of the first gear 103 drives the vertical brush strips 109 to move back and forth repeatedly, thus repeatedly rubbing against the contact groove 110. During this friction, the contact... The slot 110 carries a strong negative charge, while the vertical brush bar 109 carries a strong positive charge. The two generate static electricity through friction. This static electricity can attract dust particles in the air around the insert flat bracket 511 to its surface, reducing the amount of dust. Before the plug is inserted into the socket on the surface of the socket 411, it can attract nearby dust particles, preventing a large number of dust particles from entering the socket with the airflow when the plug is inserted into the socket and coming into contact with the metal parts inside the socket. If these dust particles accumulate on the surface of the metal parts for a long time, it will increase the contact resistance, causing the plug and socket connection to overheat and thus posing a fire risk.

[0058] It should be noted that when the extension rod 105 moves back and forth, the liquid cooling equipment housing 100 is in a de-energized state and the plug is not connected to the socket. Only after using electrostatic adsorption to clean the dust particles in the surrounding air is the plug of the equipment connected to the socket.

[0059] Furthermore, the insert flat bracket 511 and multiple insulating rods 111 are all made of insulating material, which can set a barrier between the socket component 411 and the vertical brush bar 109 to prevent static electricity from affecting the current. The insulating material is polycarbonate, which has high strength, impact resistance and good insulation. The core purpose of setting up this insulating barrier is to avoid its potential risks while taking advantage of the benefits of electrostatic adsorption, and to improve the safety and reliability of the entire system. The insulating barrier physically isolates the static-charged surface from the surrounding environment, cuts off any unintended current path, and ensures that the static charge is only used to adsorb dust and will not cause safety accidents.

[0060] according to Figure 5 As shown, a support base is fixedly installed on the inner wall of the package box 101. The servo motor 102 is set on the top of the support base to keep it stable. The first gear 103 is set at the bottom of the support base, and the first straight rack 104 is set on one side of the first gear 103. The two are meshed together.

[0061] When the servo motor 102 starts, its output shaft drives the first gear 103 to rotate synchronously. When the first gear 103 rotates, it can apply pressure to the first straight rack 104. When the two are meshed, the first straight rack 104 is driven to move horizontally, thereby adjusting the position of the multiple vertical brush bars 109 rubbing against the contact groove 110.

[0062] according to Figure 6 The diagram shows the positional distribution of the package box 101 and the mini vacuum cleaner 201. The mini vacuum cleaner 201 is located on the left side of the package box 101. When the extension rod 105 moves to the left, continue to refer to... Figure 7 The translation tube 205 installed on the mini vacuum cleaner 201 moves to the left, for reference. Figure 8 The displacement tube 301 moves to the left, causing the second straight rack 304 connected to it to move to the left, and then causing the second gear 305 meshing with it to rotate clockwise. The closing wheel 308 is fixedly sleeved on one end of the transmission bar 309, and the second gear 305 is also fixedly sleeved on the other end of the transmission bar 309. As the second gear 305 rotates, it causes the closing wheel 308 to rotate clockwise. The bottom surface of the closing wheel 308 gradually approaches the top of the through hole 307. When the two are in contact, the through hole 307 is closed, and the air pressure of the mini vacuum cleaner 201 will not continue to vacuum through this position.

[0063] This structure allows the sliding electrostatic dust collection component 1 to pre-aggregate dust particles in the air before targeted suction. The sliding electrostatic dust collection component 1 and the unblocking extension component 2 complement each other. After multiple vertical brush strips 109 repeatedly rub and electrostatically attract dust particles, as the extension rod 105 continues to move to the right, it drives the translation tube 205 to move to the right. The displacement tube 301 connected to the translation tube 205 moves to the right. Under the connection of the support rod 302 and the extension plate 303, it drives the second vertical... As the rack 304 moves to the right, it causes the second gear 305, which meshes with it, to rotate counterclockwise. This causes the closing wheel 308 to rotate counterclockwise, gradually exposing the through hole 307. Air pressure at one end of the suction head 202 is then transported through the through hole 307 and the hose 204 into the sleeve 106, L-shaped plate 107, arc-shaped plate 108, and vertical brush strip 109. The airflow through the port of the vertical brush strip 109 draws the condensed dust particles into the dust collection chamber within the miniature vacuum cleaner 201. Specifically, the sliding electrostatic suction component 1 not only attracts dust by generating static electricity through friction, but also triggers the rotational closing component 3 by moving the extension rod 105, achieving airflow regulation while preventing dust from spreading during the suction process.

[0064] When the vertical brush bar 109 rubs repeatedly against the contact groove 110, the through hole 307 is in a closed state. The purpose is to first electrostatically attract the floating dust particles and make them clump together, so as to avoid the atmospheric pressure generated when the mini vacuum cleaner 201 is started, which would further disturb the airflow and increase the speed of dust particle diffusion, and prevent dust particles from entering the socket and consuming power.

[0065] After the vertical brush 109 repeatedly rubs against the contact groove 110 to electrostatically attract dust particles, as the extension rod 105 continues to move to the right, the closing wheel 308 can rotate counterclockwise, and the through hole 307 is gradually exposed. The air force sucks the condensed dust particles into the mini vacuum cleaner 201 through the port of the vertical brush 109. The two work together to improve the efficiency of dust removal.

[0066] Preferably, the specific working process of the unblocking extension component 2 is as follows: Figure 7 As shown, the unblocking extension component 2 also includes a mini vacuum cleaner 201, a vacuum head 202, a positioning plate 203, a hose 204, and a translation tube 205. The mini vacuum cleaner 201 is located on one side of the package box 101 and is electrically connected to an external power source via a plug. The hose 204 is located between the mini vacuum cleaner 201 and one of the package sleeves 106. The package sleeve 106, the L-shaped plate 107, the arc plate 108, and the vertical brush strip 109 are interconnected. One end of the vertical brush strip 109 has a round hole to provide a space for the suction to accurately suck the clumps of dust particles into the dust collection chamber inside the mini vacuum cleaner 201.

[0067] The mini vacuum cleaner 201 is snapped onto one side of the package box 101. The vacuum head 202 is located inside the mini vacuum cleaner 201. The positioning plate 203 is fixedly installed inside the mini vacuum cleaner 201. One end of the hose 204 is inserted and connected to the bottom of the mini vacuum cleaner 201. One end of the translation tube 205 is movably inserted and connected to one side of the mini vacuum cleaner 201. The hose 204 is composed of foldable corrugated sheets. As the extension rod 105 moves, the hose 204 will be stretched and deformed under force without affecting the air pressure delivery.

[0068] The battery powers the small DC motor of the mini vacuum cleaner 201. When the mini vacuum cleaner 201 is turned on, the motor starts to rotate at high speed, driving the fan impeller connected to it to rotate as well. The fan blades rotate at high speed, quickly "throwing" the air inside the dust collection chamber of the mini vacuum cleaner 201 towards the exhaust port. As the air is continuously expelled and new air cannot be replenished in time, a low-pressure area with a partial vacuum is formed inside the dust collection chamber and behind the nozzle. Fluid will automatically flow from the high-pressure area to the low-pressure area. At this time, the outside of the mini vacuum cleaner 201 is normal atmospheric pressure, while the inside is low pressure. This pressure difference will generate a strong force, forcing the air near the hose 204 to flow rapidly into the dust collection chamber, thus sucking in dust particles through the hose 204.

[0069] It should be noted that the mini vacuum cleaner 201 has a rechargeable battery and an internal filter for easy dust removal.

[0070] Preferably, the specific working process of the rotary closure component 3 is as follows, according to Figure 8 As shown, the rotary closing assembly 3 also includes a displacement tube 301, a support rod 302, an extension plate 303, a second straight rack 304, a second gear 305, a closing disc 306, a through hole 307, a closing wheel 308, and a transmission bar 309. One end of the displacement tube 301 is inserted and connected to one end of the translation tube 205 to transmit thrust to the second straight rack 304, which drives the second gear 305 meshing with it to rotate, thereby adjusting the coverage area of ​​the closing wheel 308 and the through hole 307.

[0071] After the second straight rack 304 meshes with the second gear 305, it drives the closed wheel 308, which is fixedly sleeved at one end of the transmission bar 309, to rotate circumferentially. As the closed wheel 308 rotates, the protruding part of the closed wheel 308 fits and rotates against the surface of the closed disc 306. The closed wheel 308 gradually covers the through hole 307. The opening and closing of the through hole 307 allows the airflow of the suction head 202 to be transmitted to the ports of multiple vertical brush bars 109 through this part, which quickly sucks in the dust particles that have condensed near the ports, preventing the airflow from dispersing and feeding back to the dust particles and spreading.

[0072] Multiple insulating rods 111 are arranged at equal intervals on the inner surface of multiple inserting flat supports 511.

[0073] The closed disc 306 is fixedly installed inside the positioning disc 203, with no gap between them and a tight fit. A transmission bar 309 is inserted and connected to the middle of the top of the closed disc 306. The two ends of the transmission bar 309 are respectively fixedly fitted with a closed wheel 308 and a second gear 305. One end of the displacement tube 301 is fixedly connected to one end of the translation tube 205. One end of the support rod 302 is fixedly connected to the other end of the displacement tube 301. One side of the extension plate 303 is fixedly connected to one side of the outer wall of the support rod 302. The bottom of the second straight rack 304 is fixedly connected to the top of the extension plate 303. The second straight rack 304 and the second gear 305 are meshed together.

[0074] The rotating closing assembly 3 is located inside the miniature vacuum cleaner 201 and at the bottom of the positioning disk 203. It mainly adjusts the coverage area of ​​the closing wheel 308 and the through hole 307 through transmission.

[0075] After the dust particles are electrostatically attracted by the repeated friction of multiple vertical brush strips 109, as the extension rod 105 continues to move to the right, it drives the translation tube 205 to move to the right. The displacement tube 301 connected to the translation tube 205 moves to the right. Under the connection of the support rod 302 and the extension plate 303, it drives the second straight rack 304 to move to the right, which in turn drives the second gear 305 meshing with it to rotate counterclockwise. The closing wheel 308 can then rotate counterclockwise, and the through hole 307 is gradually exposed. The air pressure at one end of the suction head 202 will be transported through the through hole 307 and the hose 204 into the interior of the sleeve 106, L-shaped plate 107, arc plate 108 and vertical brush strips 109. The wind force sucks the condensed dust particles into the dust collection chamber opened in the mini vacuum cleaner 201 through the port of the vertical brush strip 109.

[0076] This structure allows for automatic adjustment of the exposed area of ​​the through hole 307. The through hole 307 gradually increases its exposed area, allowing the air pressure generated by the mini vacuum cleaner 201 to be slowly transported through this part into the hose 204. This enables the vacuum cleaner to draw in more air per unit time, thereby quickly drawing in a large amount of light, dispersed dust particles and preventing excessive suction from disrupting the airflow around the socket.

[0077] Server immersion liquid cooling systems primarily involve completely submerging the entire server motherboard and its heat-generating chips in a special thermally conductive yet insulating coolant. Utilizing the liquid's significantly higher thermal conductivity than air, it directly and efficiently removes the enormous heat generated during server operation. This is particularly suitable for high-density computing and artificial intelligence scenarios. It eliminates traditional fans and heat sinks, directly immersing all heat-generating components in a highly insulating and thermally conductive coolant. Through direct contact and flow between the liquid and the heat-generating surfaces, heat is efficiently dissipated. The installation sockets in server immersion liquid cooling systems primarily power the liquid cooling system itself and the submerged devices. When the plug is repeatedly inserted and removed from the socket, the air in the vicinity contains suspended dust particles. Inserting and removing the plug compresses and draws air from the socket, creating a weak airflow. This airflow disturbs and carries away the dust particles accumulated on the socket surface, causing them to float and disperse near the socket. The airflow easily carries the dust particles into the socket. Inside the socket, dust accumulates on the charged metal parts. This dust buildup increases contact resistance, causing overheating at the plug-socket connection and posing a fire risk. The abutment plate 400 is fixed to the back of the liquid cooling equipment housing 100 with bolts. At this time, multiple socket pieces 411 are gradually inserted into the socket pre-drilled slots 300. The inner surface of the socket pre-drilled slots 300 fits against the outer wall of the socket pieces 411, ensuring no gaps. The socket pieces 411 primarily supply power to the liquid cooling system itself and to the submerged equipment. Before the power plug is inserted into the socket on the surface of the socket piece 411, the liquid cooling equipment housing 100 is in a de-energized state. With the start of the servo motor 102, its output shaft rotates in both directions, which in turn drives the first gear 103 connected to it to rotate in both directions. When the first gear 103 rotates forward, it drives the first straight rack 104, which meshes with it, to move. The first straight rack 104 gradually extends out from one side of the packaging box 101. (Reference) Figure 3The extension rod 105 moves to the left. Since the wrapping sleeve 106 is fixedly sleeved to one end of the extension rod 105, it also moves to the left. With the connection of the L-shaped plate 107 and the arc-shaped plate 108, multiple vertical brush strips 109 can move to the left. The multiple vertical brush strips 109 rub against the inner surface of the contact groove 110 to the left in sequence. Since the vertical brush strips 109 are made of nylon material and the material of the inner wall of the contact groove 110 is polyester, with the forward and reverse rotation of the first gear 103, the vertical brush strips 109 move back and forth repeatedly, thus repeatedly rubbing against the contact groove 110. During the friction process, the contact groove 110 itself carries a relatively large amount of... The vertical brush bar 109 carries a strong negative charge, while the vertical brush bar 109 carries a strong positive charge. Through friction, they generate static electricity. This static electricity attracts dust particles from the air surrounding the insert flattening bracket 511, reducing the amount of dust dispersed. Before the plug is inserted into the socket 411, it attracts nearby dust particles, preventing a large amount of dust particles from entering the socket with the airflow when the plug is inserted. This avoids dust particles from accumulating on the metal parts inside the socket over time, increasing contact resistance, and causing overheating at the plug-socket connection, potentially posing a fire risk. When the extension rod 105 moves to the left, continue referring to... Figure 7 The translation tube 205 installed on the mini vacuum cleaner 201 moves to the left, for reference. Figure 8The displacement tube 301 moves to the left, causing the second straight rack 304 connected to it to move to the left, which in turn causes the second gear 305 meshing with it to rotate clockwise. The closing wheel 308 is fixedly sleeved on one end of the transmission bar 309, and the second gear 305 is also fixedly sleeved on the other end of the transmission bar 309. As the second gear 305 rotates, it causes the closing wheel 308 to rotate clockwise. The bottom surface of the closing wheel 308 gradually approaches the top of the through hole 307. When the two are in contact, the through hole 307... When in a closed state, the air pressure of the mini vacuum cleaner 201 will not continue to draw dust through this location. As the vertical brush strips 109 repeatedly rub against the contact groove 110, the through hole 307 remains closed. This is to first electrostatically attract floating dust particles, causing them to clump together. This prevents the atmospheric pressure generated when the mini vacuum cleaner 201 starts from further disrupting the airflow and accelerating the spread of dust particles, thus preventing dust particles from entering the socket and wasting power. After multiple vertical brush strips 109 repeatedly rub against and electrostatically attract dust particles, they are then... As the extension rod 105 continues to move to the right, it drives the translation tube 205 to move to the right, and the displacement tube 301 connected to the translation tube 205 moves to the right. Under the connection of the support rod 302 and the extension plate 303, it drives the second straight rack 304 to move to the right, which in turn drives the second gear 305 meshing with it to rotate counterclockwise. The closing wheel 308 can then rotate counterclockwise, and the through hole 307 is gradually exposed. The air pressure at one end of the suction head 202 will pass through the through hole 307 and the hose 204 to the wrapping sleeve 106 and the L-shaped... The plate 107, the curved plate 108, and the vertical brush bar 109 are internally transported. The air force sucks in the condensed dust particles through the port of the vertical brush bar 109. This structure can automatically adjust the exposed area of ​​the through hole 307. The through hole 307 slowly increases the exposed area, allowing the air pressure generated by the mini vacuum cleaner 201 to be slowly transported to the hose 204 through this part. More air can be sucked in per unit time, thereby quickly sucking in a large amount of light, dispersed dust particles and preventing excessive suction from disturbing the airflow around the socket.
