Description

Technical Field

[0001] The present invention relates to the technical field of server heat dissipation, and in particular to a self-dusting radiator for an AI server. Background Art

[0002] A server radiator is a device specifically designed to dissipate the heat generated during the operation of an AI server. Since AI server components such as the CPU (central processing unit) and GPU (graphics processing unit) generate a lot of heat when performing complex deep learning calculations and big data analysis tasks, the main function of the radiator is to effectively transfer this heat to the surrounding environment, thereby ensuring that the server components operate normally within the appropriate temperature range. If the server temperature is too high, it may cause performance degradation, calculation errors, or even hardware damage.

[0003] In the operation of AI servers, the radiators used mainly include air cooling and water cooling. A large amount of dust accumulation will seriously weaken the heat dissipation efficiency. For air-cooled radiators, the dust accumulated on the cooling fins is the main factor leading to poor heat dissipation. These closely arranged fins are intended to increase the heat dissipation area, but the dust accumulated in them greatly hinders heat transfer. In water-cooled radiators, the dust attached to the radiator becomes the key to affecting heat dissipation. It covers the surface of the radiator and reduces the efficiency of the radiator in dissipating the heat of the coolant to the air.

[0004] In order to maintain good heat dissipation performance, it is essential to regularly remove dust from the radiator. However, in reality, when removing dust from the cooling fins of air-cooled radiators and the radiators of water-cooled radiators, the radiator often has to be removed from the AI ​​server first. This process involves disconnecting various connection lines, unscrewing fixing screws, and many other operations. Not only is the process complicated, but it also requires caution to avoid damage to the server and radiator. Summary of the invention

[0005] The object of the present invention is to provide a self-dusting AI server radiator to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the present invention provides a radiator of a self-dust-removing AI server, comprising a heat-conducting base, wherein the heat-conducting base is fixedly mounted with heat-conducting fins, and the heat-conducting fins are fixedly mounted with heat-conducting pipes, and a mounting ring is arranged inside the heat-conducting pipe, and a servo motor is fixedly mounted on the top of the mounting ring, and a servo motor is fixedly mounted on the top of the mounting ring, and a driving end of the mounting ring is connected with an umbrella-shaped gear, and the umbrella-shaped gear is meshingly connected with a first bevel gear ring, and the first bevel gear ring is rotatably connected with the top of the mounting ring, and the first bevel gear ring is meshingly connected with a second bevel gear ring; a slider is fixedly mounted on the mounting ring, and a plurality of mounting tubes are fixedly mounted on the circumferential outer wall of the slider, an air cavity is opened inside the slider, and one end of the mounting tube extends into the air cavity; two round blocks are fixedly mounted on one end of the mounting tube away from the slider, and the other round block is rotatably connected to one end of the mounting tube close to the slider, and a plurality of air outlet pipes are fixedly mounted between the two round blocks, and the second bevel gear ring is fixedly mounted on the outer wall of the round block close to the slider.

[0007] Furthermore, a plurality of telescopic springs and a multi-section telescopic rod are fixedly installed between the mounting tube and the round block away from the slider, and the telescopic spring is sleeved on the outer wall of the multi-section telescopic rod.

[0008] Furthermore, a mounting plate is fixedly mounted on the top of the heat conducting tube, an air pump is fixedly mounted on the top of the mounting plate, the air pump is connected to a telescopic air pipe, and one end of the telescopic air pipe is connected to the air cavity.

[0009] Furthermore, a DC motor is fixedly installed on the top of the mounting plate, a fixed rod is connected to the driving end of the DC motor, a fixed block is fixedly installed on the bottom of the fixed rod, a guide rod is installed on the bottom of the fixed block, the fixed rod, the fixed block and the guide rod form a Z shape, a reciprocating screw is fixedly installed between the heat-conducting base and the mounting plate, and the slider is threadedly connected to the outer wall of the reciprocating screw.

[0010] Furthermore, a limit block is fixedly mounted on the bottom end of the guide rod, and the other end of the limit block is sleeved on the outer wall of the reciprocating screw rod.

[0011] Furthermore, a heat insulation layer is installed on the top of the heat-conducting base and the bottom of the mounting plate.

[0012] Furthermore, a protective cover is provided on the exterior of the DC motor.

[0013] Furthermore, a dust cover is provided on the outer wall of the servo motor.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, after the motor is started, its driving end drives the bevel gear to rotate at high speed. Through the meshing between the gears, the rotational power is transmitted to the first bevel gear ring and the second bevel gear ring in sequence, making them rotate counterclockwise. The guide telescopic rod limits the round block away from the slider so that it can only stretch back and forth, ensuring that one end of the air outlet pipe is fixed. When the second bevel gear ring rotates, it drives the two round blocks connected to it to rotate synchronously, causing the air outlet pipe to twist. The system will increase the speed of the servo motor, increase the rotation amplitude of the round block driven by the second bevel gear ring, and increase the helicity. The spiral air outlet pipe makes the ejected gas form a rotating airflow, which generates a strong centrifugal force when impacting the heat sink fins, which can effectively remove dust. The larger the amount of dust, the stronger the centrifugal force. The radiator can automatically adjust the dust removal force accordingly to ensure the cleanliness of the heat sink fins and maintain the stable operation of the AI ​​server.

[0015] 2. In the present invention, when the amount of dust is small, the servo motor, the bevel gear and the first bevel gear ring work together to rotate the second bevel gear ring clockwise, driving the air outlet pipe to be straight. At this time, the end of the air outlet pipe away from the slider pushes the round block outward, stretching the slider, and the air outlet pipe in a straight state can provide a gentle and concentrated airflow to clean the dust. By adjusting the above gear matching, the movement of the second bevel gear ring is accurately controlled, and then the state of the air outlet pipe is controlled to achieve accurate control of the dust removal force, which avoids excessive airflow due to large spirality, prevents energy waste and unnecessary impact on the heat sink fins.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 6 , the present invention provides a technical solution: See also Figure 1-Figure 6 As shown, a radiator of a self-dusting AI server comprises a heat-conducting base 1, on which a heat-dissipating fin 2 is fixedly mounted, on which a heat-conducting pipe 3 is fixedly mounted, inside of which a mounting ring 4 is arranged, a servo motor 5, fixedly mounted on the top of the mounting ring 4, a driving end of the mounting ring 4 is connected with a parasol gear 6, the parasol gear 6 is meshedly connected with a first bevel gear ring 7, the first bevel gear ring 7 is rotatably connected to the top of the mounting ring 4, and the first bevel gear ring 7 is meshedly connected with a second bevel gear ring 8; a slider 13, fixedly mounted on the mounting ring 4, a plurality of mounting tubes 9 are fixedly mounted on the circumferential outer wall of the slider 13, an air cavity 12 is opened inside the slider 13, and one end of the mounting tube 9 extends into the air cavity 12; two round blocks 10, fixedly mounted on one end of the mounting tube 9 away from the slider 13, the other round block 10 is rotatably connected to one end of the mounting tube 9 close to the slider 13, a plurality of air outlet pipes 11 are fixedly mounted between the two round blocks 10, and the second bevel gear ring 8 is fixedly mounted on the outer wall of the round block 10 close to the slider 13.

[0020] When the detection system accurately detects that excessive dust has accumulated on the surface of the heat sink fins 2, it will immediately start the servo motor 5 intelligently according to the specific amount of dust accumulation. The servo motor 5 serves as the power starting point of the entire dust removal mechanism. Once started, its driving end begins to rotate at a high speed and stably, and with the help of a tight mechanical connection, it drives the connected bevel gear 6 to rotate synchronously.

[0021] The rotation of the bevel gear 6, with the help of the precise meshing relationship between the teeth, efficiently transmits the rotational power to the first bevel gear ring 7, pushing the first bevel gear ring 7 to start rotating smoothly at a predetermined speed. Since the first bevel gear ring 7 is also tightly meshed with the second bevel gear ring 8, this rotational power can continue to be transmitted, thereby driving the second bevel gear ring 8 to start rotating in the counterclockwise direction.

[0022] During the entire transmission process, the guide telescopic rod plays an indispensable role. It limits the movement of the round block 10 away from the slider 13, so that it can only telescope and move along the front and rear directions, and cannot perform any rotational movement at all. This precise constraint mechanism ensures that one end of the air outlet pipe 11 is always in a fixed state, laying the foundation for the subsequent unique movement of the air outlet pipe 11.

[0023] As the second bevel gear ring 8 continues to rotate, the round block 10 fixedly mounted on the outer wall thereof near the slider 13 and another round block 10 connected thereto through the mounting tube 9 begin to rotate synchronously. Since a plurality of air outlet pipes 11 are evenly distributed between the two round blocks 10, when the round block 10 near the slider 13 rotates, the air outlet pipes 11 will twist accordingly.

[0024] The spiral shape formed by twisting the outlet pipe 11 is not fixed, but is closely related to the amount of dust on the heat sink fins 2. When the amount of dust detected is larger, the system will automatically adjust the operating parameters of the servo motor 5, such as increasing its rotation speed, so that the second bevel gear ring 8 drives the round block 10 to rotate with a larger amplitude, thereby causing the outlet pipe 11 to form a larger spiral shape.

[0025] During the gas injection stage, the path and method of the gas ejected from the outlet pipe 11 will be significantly changed due to the spiral shape of the outlet pipe 11. The spiral outlet pipe 11 allows the ejected gas to form a unique rotating airflow. When this rotating airflow hits the heat sink fin 2, it will generate a stronger centrifugal force on the dust attached to its surface.

[0026] Compared with the traditional linear jet method, the effect of this centrifugal force is extremely significant. Under the strong action of centrifugal force, the dust that was originally tightly attached to the surface of the heat sink fin 2 can be more easily detached from the fin surface. Moreover, the greater the amount of dust, the greater the spirality of the outlet pipe 11, and the stronger the centrifugal force generated. This means that the radiator can automatically adjust the dust removal intensity according to the actual situation of dust accumulation, ensuring that the heat sink fins 2 can be efficiently and thoroughly cleaned under various dust pollution levels, thereby always maintaining the excellent heat dissipation performance of the AI ​​server radiator and ensuring the stable and efficient operation of the AI ​​server.

[0027] See also Figure 6 A plurality of telescopic springs 23 and a multi-section telescopic rod are fixedly installed between the mounting tube 9 and the round block 10 away from the slider 13, and the telescopic springs 23 are sleeved on the outer wall of the multi-section telescopic rod.

[0028] When the amount of dust is relatively small and the spirality of the air outlet pipe 11 is not required to be large, the servo motor 5, the bevel gear 6, and the first bevel gear ring 7 can cooperate with each other to make the second bevel gear ring 8 move clockwise, and the state of the air outlet pipe 11 is in a relatively straight state. The end of the air outlet pipe 11 away from the slider 13 will generate an external thrust on the round block 10 away from the slider 13, and the slider 13 is stretched by the thrust.

[0029] When the amount of dust is small, the air outlet pipe 11 is in a relatively straight state, and can provide a relatively gentle and concentrated airflow to clean the dust. The movement direction of the second bevel gear ring 8 is finely adjusted through the cooperation of the servo motor 5, the umbrella gear 6 and the first bevel gear ring 7, so as to control the state of the air outlet pipe 11. It is possible to achieve precise dust removal force control according to the actual situation of the dust amount. This precise control avoids the situation where the amount of dust is small and the air outlet pipe 11 has a large spirality, which may cause excessive airflow, resulting in energy waste or unnecessary impact on the heat sink fins 2.

[0030] See also Figure 1 A mounting plate 19 is fixedly installed on the top of the heat conducting pipe 3 , an air pump 20 is fixedly installed on the top of the mounting plate 19 , the air pump 20 is connected to a telescopic air pipe 21 , and one end of the telescopic air pipe 21 is connected to the air cavity 12 .

[0031] Since the mounting plate 19 is located on the top of the heat pipe 3, the effect of the heat conducted by the heat pipe 3 on the air pump 20 can be reduced to a certain extent. The heat pipe 3 is a component used to transfer and disperse heat, and the air pump 20 is a device for driving the flow of gas. Separating the two by the mounting plate 19 can prevent excessive heat from being conducted to the air pump 20, thereby ensuring the performance and life of the air pump 20 and avoiding failure or reduced efficiency of the air pump 20 due to overheating.

[0032] The air pump 20, as the core component for generating airflow, provides a stable gas power source for the entire dust removal system. It can generate sufficient airflow as needed to provide strong support for subsequent dust removal operations. For example, when dust removal operations are required, the air pump 20 can generate sufficient air pressure to transport the gas to the corresponding position through the telescopic air pipe 21, thereby pushing the clean gas to the outlet pipe 11 to remove dust from the heat sink fins 2.

[0033] The use of the telescopic air tube 21 is very flexible. When the slider 13 drives the mounting tube 9 and the air outlet pipe 11 to perform various complex movements, such as the up and down movement and circular rotation of the slider 13 on the reciprocating screw 18, the telescopic air tube 21 can be extended or contracted accordingly to avoid damage to the pipeline or restriction of the movement of the slider 13 caused by the rigid connection. For example, when the slider 13 moves up and down or rotates, the telescopic air tube 21 can be extended and contracted to adapt to the change of its position, thereby ensuring that the gas passage between the air pump 20 and the air cavity 12 is always unobstructed.

[0034] See also Figure 3-4 A DC motor 14 is fixedly installed on the top of the mounting plate 19, a fixing rod 15 is connected to the driving end of the DC motor 14, a fixing block 16 is fixedly installed on the bottom of the fixing rod 15, a guide rod 17 is installed on the bottom of the fixing block 16, the fixing rod 15, the fixing block 16, and the guide rod 17 form a Z shape, a reciprocating screw 18 is fixedly installed between the heat-conducting base 1 and the mounting plate 19, and the slider 13 is threadedly connected to the outer wall of the reciprocating screw 18.

[0035] When the spirality of the air outlet pipe 11 is successfully adjusted to a suitable state through the above operation, the system will start the DC motor 14. The driving end of the DC motor 14 serves as a power source and starts to drive multiple components connected to it, including the fixed rod 15, the bevel gear 6 and the guide rod 17. During this process, the slider 13 is sleeved on the outer wall of the guide rod 17, and the guide rod 17 starts to rotate under the drive of the DC motor 14.

[0036] Due to the unique matching relationship between the slider 13 and the reciprocating screw 18, when the guide rod 17 starts to rotate, the slider 13 will rotate on the outer wall of the reciprocating screw 18. At the same time, more importantly, the slider 13 will move up and down along the thread while rotating according to the thread structure of the reciprocating screw 18.

[0037] The up and down movement and rotational motion of the slider 13 can drive the mounting tube 9 and the air outlet pipe 11 to perform complex and orderly movements. On the one hand, the mounting tube 9 and the air outlet pipe 11 will clean the heat sink fins 2 from different heights above as the slider 13 moves up and down, thereby realizing multi-directional cleaning of the heat sink fins 2 in the vertical direction. On the other hand, the circular rotation of the slider 13 will further drive the mounting tube 9 and the air outlet pipe 11 to perform circular rotational motion together, so that the airflow ejected from the air outlet pipe 11 can cover various circumferential positions of the heat sink fins 2, avoiding cleaning dead corners that may occur in traditional cleaning methods.

[0038] This multi-dimensional cleaning method makes full use of the linkage between the slider 13, the mounting tube 9 and the exhaust pipe 11, and combines the unique structure of the guide rod 17 and the reciprocating screw 18 to provide a more comprehensive, efficient and dead-angle cleaning service for the heat sink fins 2, thereby ensuring that the heat sink fins 2 always maintain good heat dissipation performance and providing strong guarantee for the stable operation of the AI ​​server.

[0039] See also Figure 5 A limit block 22 is fixedly installed on the bottom end of the guide rod 17 , and the other end of the limit block 22 is sleeved on the outer wall of the reciprocating screw rod 18 .

[0040] One end of the limit block 22 is fixedly installed on the bottom end of the guide rod 17 to prevent the guide rod 17 from accidentally falling off the reciprocating screw 18 during the process of rotating and driving the slider 13 to move. When the entire system is working, the guide rod 17 will drive the slider 13 to perform complex movements, such as rotation and up and down movement along the reciprocating screw 18. These movements may generate a certain centrifugal force or axial force. The limit block 22 is like a safety lock, which is firmly fixed on the guide rod 17 to prevent the guide rod 17 from detaching from the reciprocating screw 18 when subjected to external force or vibration, thereby ensuring the stability and safety of the system structure.

[0041] The other end of the limit block 22 is sleeved on the outer wall of the reciprocating screw 18, which can limit the movement range of the guide rod 17 and the slider 13. It can prevent the slider 13 from excessively moving on the reciprocating screw 18 and prevent the slider 13 from sliding out of the effective working area of ​​the screw. For example, when the slider 13 moves up and down along the reciprocating screw 18, the limit block 22 can serve as a boundary to ensure that the slider 13 does not exceed the top or bottom limit position of the reciprocating screw 18, thereby avoiding structural damage or collision between moving parts caused by overtravel, thereby ensuring the normal operation of the entire motion system.

[0042] See also Figure 1-2 The top of the heat-conducting base 1 and the bottom of the mounting plate 19 are both installed with a heat insulation layer.

[0043] The thermal insulation layer at the bottom of the mounting plate 19 can effectively prevent the heat conducted by the heat pipe 3 and the heat base 1 from being transferred to the air pump 20. When the AI ​​server is running, the heating element generates a large amount of heat, which is transferred through the heat base 1 and the heat pipe 3. If the air pump 20 is heated for a long time, the performance of its internal motor and electronic components will be affected, such as the insulation performance of the motor windings will decrease and the parameters of the electronic components will drift, resulting in failure of the air pump 20 or shortened life. The thermal insulation layer can keep the working environment temperature of the air pump 20 suitable to ensure its stable operation.

[0044] For temperature-sensitive components mounted near the mounting plate 19, the thermal insulation layer can prevent performance degradation due to overheating.

[0045] See also Figure 1 The DC motor 14 is externally covered with a protective cover.

[0046] During the daily operation, maintenance or transportation of the radiator, some accidental collisions may occur. The protective cover can protect the DC motor 14 from direct collisions with external objects and reduce the risk of physical damage to the motor. For example, when personnel accidentally touch the motor or other equipment parts during server maintenance operations, the protective cover can withstand part of the impact force to avoid damage to key parts such as the motor casing, motor shaft or terminal, thereby ensuring the integrity and safety of the motor.

[0047] See also Figure 4 The outer wall of the servo motor 5 is provided with a dust cover.

[0048] For the bearing part of the motor, the invasion of dust may increase the friction, making the rotation of the motor become unsmooth, and further affecting the speed and torque output of the motor. With a dust cover, the moving parts such as the bearings can be kept clean, ensuring that the servo motor 5 can drive the bevel gear 6 and other parts with stable performance, ensuring the normal operation of the dust removal system, and enabling the heat sink fins 2 to perform dust removal operations in a predetermined manner.

[0049] In the operating environment of the server, dust is everywhere. The servo motor 5 is a key power component in the radiator dust removal system. There are many precise structures inside it, such as windings, bearings, and brushes. If it is a brush motor, the dust cover can effectively prevent dust from entering the motor and prevent dust from accumulating on these precise components. For example, too much dust attached to the motor windings may affect the heat dissipation performance of the motor, causing the winding temperature to be too high, thereby reducing the insulation performance and even causing a short circuit failure. The dust cover is like a loyal guard, which greatly reduces this risk.
