Description

Technical Field

[0001] The invention relates to the technical field of heat dissipation, in particular to an auxiliary heat dissipation device for installing a computer graphics card. Background Art

[0002] Most computer graphics cards use air cooling to reduce the temperature of the graphics card. That is, the high-speed rotation of the rotating blades generates airflow to bring out the heat generated by the operation of the graphics card, thereby cooling the GPU.

[0003] The deflection angle of the fan blades will directly affect the direction and speed of air flow. In the prior art, the fan blade angle of the cooling fan of the graphics card is fixed. If the fan blade angle does not meet the current cooling requirements, it will cause poor air flow and reduce the cooling efficiency. If the fan cannot adjust the fan blade angle according to the actual cooling requirements, a higher speed will be required to maintain the cooling effect, thereby increasing energy consumption. The fixed fan blade angle will cause the temperature of the graphics card body to fluctuate greatly. At high loads, the heat dissipation is insufficient, and at low loads, the heat dissipation is excessive, affecting the stability and life of the graphics card body. Since the fan blade angle cannot be adjusted according to actual needs, the fan will work at a high speed for a long time, which will increase wear and shorten the service life of the fan.

[0004] When the cooling fan rotates, dust particles in the air will be sucked in and attached to the isolation plate. The graphics card body will generate heat when it is running. In areas with higher temperatures, the air density is usually lower, because the increase in temperature causes the average kinetic energy of gas molecules to increase, and the distance between molecules increases, making the air thinner. In this case, the air flow is not as stable as in areas with lower temperatures, and the movement path of dust particles in the air is more difficult to be discharged, and it is easier to accumulate in these areas, and then the areas with higher temperatures are more likely to absorb dust. If dust adheres to the isolation net of the graphics card (usually refers to the dust net near the graphics card fan), it will hinder air circulation and reduce the fan's air intake and exhaust efficiency, thereby reducing the heat dissipation effect. Due to the reduced heat dissipation efficiency, the temperature of the graphics card's radiator will increase. Long-term high-temperature operation will accelerate the aging of the hardware and even damage the graphics card. Poor heat dissipation will cause unstable system operation, blue screen, freeze or restart problems. In order to cope with poor heat dissipation, the graphics card fan will increase the speed to increase the heat dissipation efficiency, which will cause the fan noise to increase. Long-term work in a high-temperature environment will shorten the service life of the graphics card and other related hardware.

[0005] Therefore, an auxiliary heat dissipation device for installing a computer graphics card is proposed to solve the above problems. Summary of the invention

[0006] In view of this, the technical problem to be solved by the present invention is to propose an auxiliary heat dissipation device for installing a computer graphics card, so as to solve the problem that the fan blade angle of the cooling fan of the graphics card in the prior art is fixed. If the fan blade angle does not meet the current heat dissipation requirements, it will cause poor air flow and reduce the heat dissipation efficiency. When the heat dissipation efficiency is reduced, the radiator temperature of the graphics card will increase. Long-term high-temperature operation will accelerate the aging of the hardware and even damage the graphics card. Poor heat dissipation will cause unstable system operation and cause blue screen, freeze or restart.

[0012] Preferably, the graphics card body is internally rotatably connected to a second rotating column, an arc groove is provided inside the second rotating column, a sliding rod is slidably connected inside the second rotating column, the bottom surface of the second rotating column is rotatably connected to a second cylinder, and the arc surface of the second cylinder is fixedly connected to a nozzle.

[0013] Preferably, the auxiliary cleaning mechanism also includes a rack, which is fixedly connected to a side of the graphics card body close to the electric telescopic rod, and the electric telescopic rod is fixedly connected to a side of the graphics card body close to the rack, and a third rotating column is rotatably connected to the side of the auxiliary frame close to the rack.

[0014] Preferably, the top surface of the third rotating column is fixedly connected to the first gear, the bottom surface of the third rotating column is fixedly connected to the direction converter, the inner wall of the auxiliary frame is rotatably connected to a cleaning roller, and the cleaning roller is fixedly connected to the end of the direction converter away from the third rotating column, the interior of the auxiliary frame is fixedly connected to a dust suction pipe, the side of the auxiliary frame is fixedly connected to a collecting trough, and the bottom surface of the graphics card body is connected to a dust net through a transmission column.

[0015] Preferably, the sliding rod is slidably connected to the inside of the second cylinder.

[0016] Preferably, the dust suction pipe is connected to the collecting tank.

[0017] Compared with the prior art, the present invention provides an auxiliary heat dissipation device for installing a computer graphics card, which has the following beneficial effects:

[0018] 1. The deflection angle of the fan blade body can be adjusted by cooperating with the first bevel gear, the second bevel gear and the fan blade in the auxiliary heat dissipation mechanism. The fan blade body can be optimized by optimizing the inclination angle to increase the fan's wind output, so that more cold air can flow through the radiator, thereby improving the heat dissipation efficiency. Adjusting the fan blade angle can increase the fan's wind pressure, so that the airflow can pass through the heat dissipation fins more effectively to help take away the heat. A larger inclination angle of the fan blade can increase the fan's wind output, because a larger angle means that the fan blade can push more air when rotating, thereby improving the heat dissipation efficiency. A larger inclination angle of the fan blade can increase the fan's wind pressure, so that the airflow can pass through the heat dissipation fins more effectively to help take away the heat. When the graphics card body is running at high load, more air volume and air pressure are needed to dissipate heat. A larger fan blade tilt angle can better adapt to this scenario. A smaller fan blade tilt angle can reduce the noise generated by the airflow at the edge of the fan blade, making the fan run quieter. A smaller fan blade tilt angle means that the fan requires less energy when running, thereby reducing energy consumption. When the graphics card body is in low load or standby state, a smaller fan blade tilt angle can provide sufficient air volume while maintaining a low noise level. A smaller fan blade tilt angle can reduce the load of the fan, thereby extending the service life of the fan.

[0019] 2. By cooperating with each other to form a piston movement among the second rotating column, the sliding rod, the second cylinder and the nozzle in the auxiliary heat dissipation mechanism, sound-absorbing paint can be sprayed on the fan blades. The sound-absorbing paint can absorb part of the sound waves, reduce the reflection and propagation of the sound waves, and thus reduce the noise level when the fan is running. The movement of the piston can ensure that the sound-absorbing paint is evenly sprayed on the surface of the fan blades to form a uniform coating, which helps to ensure the consistency of the sound absorption effect and improve the acoustic performance. Using a piston for spraying can complete the work faster than manual brushing and improve production efficiency. The movement of the piston can reduce the impact of human factors on the coating quality, such as uneven brushing, missing coating and other problems. For fan blades with complex shapes, the piston can more easily spray the sound-absorbing paint to hard-to-reach parts to ensure full coverage. The uniform coating of the sound-absorbing paint can provide better sound absorption performance and reduce the noise generated when the fan is running. The sound-absorbing paint can also provide a certain protection to prevent the fan blades from corrosion, wear or other damage.

[0020] 3. Through the cooperation between the third rotating column, the direction converter and the cleaning roller in the auxiliary cleaning mechanism, the dust on the isolation net can be cleaned by the rotation of the cleaning roller. The cleaning roller can be used to quickly clean the dust without disassembling the graphics card, saving the time of disassembling and reinstalling the graphics card body. Users do not need to have professional skills and anyone can operate it easily. Manual disassembly of the graphics card body will cause some risks, such as electrostatic damage, connector damage or other accidental damage, and using a cleaning roller for cleaning can avoid these risks and protect the integrity of the graphics card body and other hardware. The cleaning roller can clean small gaps and hard-to-reach places, and can more effectively remove accumulated dust. Combined with the dust suction device, it can ensure that dust no longer spreads to other components and keep the internal environment clean. Regular use of the cleaning roller can effectively prevent dust accumulation, thereby reducing the risk of overheating of the graphics card body and other components, which can extend the service life of the equipment and reduce the performance degradation of the graphics card body caused by overheating.

[0034] The present invention is further described in detail below based on the accompanying drawings and embodiments.

[0035] Example

[0036] Please refer to Figures 1 to 6 As shown:

[0037] In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides an auxiliary heat dissipation device for installing a computer graphics card, comprising: a graphics card body 1, a temperature sensor 2 is fixedly connected to the inside of the graphics card body 1, an auxiliary heat dissipation mechanism for assisting the graphics card body 1 in dissipating heat is arranged inside the graphics card body 1, and an auxiliary cleaning mechanism for cleaning dust is arranged on the outer surface of the graphics card body 1;

[0038] The auxiliary heat dissipation mechanism comprises a first cylinder 301, and an auxiliary cylinder 303 for controlling the heat dissipation angle is fixedly connected to the bottom surface of the first cylinder 301;

[0039] The auxiliary heat dissipation mechanism also includes an auxiliary cone 309. The first cylinder 301 is fixedly connected to the inside of the graphics card body 1. The auxiliary cone 309 is fixedly connected to the inside of the graphics card body 1. The bottom surface of the first cylinder 301 is fixedly connected to the first cylinder 302. The auxiliary cylinder 303 is located inside the first cylinder 302.

[0040] A pawl 304 is fixedly connected to one side of the auxiliary cylinder 303 away from the first cylinder 301, a ratchet 305 is meshed on the outer surface of the pawl 304, a first bevel gear 306 is fixedly connected to the bottom surface of the ratchet 305, and the first bevel gear 306 is rotatably connected to the inside of the first cylinder 302, a fan blade 308 is rotatably connected to the inside of the first cylinder 302, and the fan blade 308 is arranged in a circular array around the center of the first cylinder 302, and a second bevel gear 307 is fixedly connected to one side of the fan blade 308 close to the first bevel gear 306.

[0041] The graphics card body 1 is internally rotatably connected to a second rotating column 310, an arc groove is provided inside the second rotating column 310, a sliding rod 311 is slidably connected inside the second rotating column 310, and the bottom surface of the second rotating column 310 is rotatably connected to a second cylinder 312, and a nozzle 313 is fixedly connected to the arc surface of the second cylinder 312.

[0042] Among them: the temperature sensor 2 is electrically connected to the driving device, the driving device drives the auxiliary cylinder 303 to rotate clockwise and counterclockwise, the pawl 304 cannot drive the ratchet 305 to rotate when it rotates clockwise, and the pawl 304 drives the ratchet 305 to rotate when it rotates counterclockwise, the auxiliary frustum 309 is provided with sound-absorbing material, a belt is connected between the first cylinder 301 and the second rotating column 310, and a spray hole is opened on the arc surface on one side of the nozzle 313 close to the fan blade 308.

[0043] In the prior art, the angle of the cooling fan blade 308 of the graphics card body 1 is fixed. If the angle of the fan blade 308 does not meet the current cooling demand, it will cause poor air flow and reduce the cooling efficiency. If the fan cannot adjust the angle of the fan blade 308 according to the actual cooling demand, a higher speed will be required to maintain the cooling effect, thereby increasing energy consumption. The fixed angle of the fan blade 308 will cause the temperature of the graphics card body 1 to fluctuate greatly. Under high load, the heat dissipation is insufficient, and under low load, the heat dissipation is excessive, affecting the stability and life of the graphics card body 1. Since the angle of the fan blade 308 cannot be adjusted according to actual needs, the fan will increase wear and shorten the service life of the fan when working at a high speed for a long time. Compared with the prior art, the deflection angle of the fan blade 308 can be adjusted by cooperating with the first bevel gear 306, the second bevel gear 307 and the fan blade 308 in the auxiliary cooling mechanism. By optimizing the inclination angle of the fan blade 308, the fan's air volume output can be increased, so that more cold air can flow through the radiator, thereby improving the cooling efficiency. Adjusting the angle of the fan blade 308 can increase The wind pressure of the fan allows the airflow to pass through the cooling fins more effectively to help remove heat. A larger inclination angle of the fan blades 308 can increase the fan's air volume output, because a larger angle means that the fan blades 308 can push more air when rotating, thereby improving the heat dissipation efficiency. A larger inclination angle of the fan blades 308 can increase the fan's wind pressure, allowing the airflow to pass through the cooling fins more effectively to help remove heat. When the graphics card body 1 is running at high load, more air volume and air pressure are required to dissipate heat. A larger inclination angle of the fan blades 308 can better adapt to this scenario. A smaller inclination angle of the fan blades 308 can reduce the noise generated by the airflow at the edge of the fan blades 308, making the fan run quieter. A smaller inclination angle of the fan blades 308 means that the fan requires less energy when running, thereby reducing energy consumption. When the graphics card body 1 is in low load or standby state, a smaller inclination angle of the fan blades 308 can provide sufficient air volume while maintaining a low noise level. A smaller inclination angle of the fan blades 308 can reduce the load of the fan, thereby extending the service life of the fan.

[0044] For further examples, please refer to Figures 7 and 8 As shown:

[0045] The auxiliary cleaning mechanism includes an electric telescopic rod 402, one end of which is fixedly connected to an auxiliary frame 403 for cleaning the graphics card body 1;

[0046] The auxiliary cleaning mechanism also includes a rack 401, which is fixedly connected to one side of the graphics card body 1 close to the electric telescopic rod 402, and the electric telescopic rod 402 is fixedly connected to one side of the graphics card body 1 close to the rack 401. The auxiliary frame 403 is rotatably connected to a third rotating column 404 on one side close to the rack 401.

[0047] The top surface of the third rotating column 404 is fixedly connected to the first gear 405, the bottom surface of the third rotating column 404 is fixedly connected to the direction converter 406, the inner wall of the auxiliary frame 403 is rotatably connected to the cleaning roller 407, and the cleaning roller 407 is fixedly connected to the end of the direction converter 406 away from the third rotating column 404, the interior of the auxiliary frame 403 is fixedly connected to the dust suction pipe 408, the side of the auxiliary frame 403 is fixedly connected to the collecting tank 409, and the bottom surface of the graphics card body 1 is connected to the dustproof net 410 through a transmission column.

[0048] Among them: the cylinder drives the electric telescopic rod 402 to extend and retract, the rack 401 is meshed and connected with the first gear 405, the outer surface of the cleaning roller 407 is provided with a soft brush, the inside of the dust suction pipe 408 is provided with a dust suction device, and the dust suction pipe 408 is provided with a dust suction hole on the arc surface close to the cleaning roller 407.

[0049] In the prior art, if dust adheres to the isolation net of the graphics card body 1 (usually refers to the dust net 410 near the fan of the graphics card body 1), it will hinder air circulation and reduce the air intake and exhaust efficiency of the fan, thereby reducing the heat dissipation effect. Due to the reduced heat dissipation efficiency, the temperature of the radiator of the graphics card body 1 will increase. Long-term high-temperature operation will accelerate the aging of the hardware and even damage the graphics card body 1. Poor heat dissipation will cause unstable system operation, blue screen, freeze or restart problems. In order to cope with poor heat dissipation, the fan of the graphics card body 1 will increase the speed to increase the heat dissipation efficiency, which will cause the fan noise to increase. Long-term operation in a high-temperature environment will shorten the service life of the graphics card body 1 and other related hardware. Compared with the prior art, the auxiliary cleaning mechanism is used to improve the heat dissipation efficiency of the graphics card body 1. The third rotating column 404, the direction converter 406 and the cleaning roller 407 cooperate with each other, and the dust on the isolation net can be cleaned by the rotation of the cleaning roller 407. Compared with manual dust blowing or wiping with a cloth, the cleaning roller 407 can more thoroughly remove the dust that is difficult to reach on the heat dissipation net. When manually blowing dust or wiping, the surface of the graphics card body 1 may be accidentally scratched or damaged. The cleaning roller 407 will not cause such a risk and the graphics card body 1 can be safely cleaned. The use of the cleaning roller 407 is very simple. Just roll the roller on the heat dissipation net without complicated operating steps. The cleaning roller 407 can reduce the problem of imbalance of the fan blades 308 caused by dust accumulation, thereby reducing the noise generated during heat dissipation and shortening and extending the life of the fan blades 308.

[0050] Everything in the above example works like this:

[0051] In the initial state: the auxiliary frame 403 is located at one end of the graphics card body 1.

[0052] The following is the working process of the auxiliary heat dissipation mechanism adjusting the tilt angle of the fan blade 308:

[0053] When in use, the driving device drives the auxiliary cylinder 303 to rotate clockwise, and the rotation of the auxiliary cylinder 303 drives the first cylinder 301 fixedly connected thereto to rotate, and the rotation of the first cylinder 301 drives the first cylinder 302 fixedly connected thereto to rotate, and the rotation of the first cylinder 302 drives the fan blade 308 rotatably connected thereto to rotate together, thereby performing heat dissipation treatment on the graphics card body 1. When the temperature sensor 2 detects that the temperature inside the graphics card body 1 is too high, the driving device drives the auxiliary cylinder 303 to rotate counterclockwise, and the clockwise rotation of the pawl 304 cannot drive the ratchet 305 to rotate, and the counterclockwise rotation of the auxiliary cylinder 303 drives the The pawl 304 fixedly connected thereto rotates, because the counterclockwise rotation of the pawl 304 can drive the ratchet 305 to rotate, that is, the rotation of the pawl 304 drives the ratchet 305 to rotate, and the rotation of the ratchet 305 drives the first bevel gear 306 fixedly connected thereto to rotate together, and the rotation of the first bevel gear 306 drives the second bevel gear 307 meshing therewith to rotate together, so that the fan blade 308 fixedly connected to the second bevel gear 307 deflects, thereby controlling the deflection angle of the fan blade 308, and then the driving device continues to drive the auxiliary cylinder 303 to rotate clockwise to dissipate heat for the graphics card body 1, and by optimizing the fan blade 308 The tilt angle of the fan can increase the air volume output of the fan, so that more cold air can flow through the radiator, thereby improving the heat dissipation efficiency. Adjusting the angle of the fan blade 308 can increase the wind pressure of the fan, so that the airflow can pass through the heat dissipation fins more effectively to help take away the heat. A larger tilt angle of the fan blade 308 can increase the air volume output of the fan, because a larger angle means that the fan blade 308 can push more air when rotating, thereby improving the heat dissipation efficiency. A larger tilt angle of the fan blade 308 can increase the wind pressure of the fan, so that the airflow can pass through the heat dissipation fins more effectively to help take away the heat. When the graphics card body 1 is running at high load, When the graphics card body 1 is in low load or standby state, the smaller fan blade 308 tilt angle can provide sufficient air volume while maintaining a low noise level. The smaller fan blade 308 tilt angle can reduce the noise generated by the airflow at the edge of the fan blade 308, making the fan run more quietly. The smaller fan blade 308 tilt angle means that the fan requires less energy when running, thereby reducing energy consumption. When the graphics card body 1 is in low load or standby state, the smaller fan blade 308 tilt angle can provide sufficient air volume while maintaining a low noise level. The smaller fan blade 308 tilt angle can reduce the load of the fan, thereby extending the service life of the fan.

[0054] Since a belt is provided for transmission connection between the first cylinder 301 and the second rotating cylinder 310, and an arc groove is provided inside the second rotating cylinder 310, which is mainly used to control the sliding rod 311 to slide up and down, that is, the rotation of the first cylinder 301 drives the second rotating cylinder 310 connected thereto to rotate together, and the rotation of the second rotating cylinder 310 drives the sliding rod 311 connected thereto to move up and down inside the second cylinder 312. Since a spray hole is provided on the arc surface of the nozzle 313 on one side close to the fan blade 308, that is, when the sliding rod 311 moves downward, the sound-absorbing paint in the second cylinder 312 is sprayed onto the surface of the fan blade 308 through the nozzle 313. When the sliding rod 311 moves upward, the sound-absorbing paint is injected into the second cylinder 312 through the automatic sound-absorbing paint device. The sound-absorbing paint can absorb part of the sound waves and reduce the sound waves. The reflection and transmission of noise can be reduced, thereby reducing the noise level when the fan is running. The movement of the piston can ensure that the sound-absorbing paint is evenly sprayed on the surface of the fan blade 308 to form a uniform coating, which helps to ensure the consistency of the sound absorption effect and improve the acoustic performance. Using a piston for spraying can complete the work faster than manual brushing, thereby improving production efficiency. The movement of the piston can reduce the impact of human factors on the coating quality, such as uneven brushing and missing coating. For fan blades 308 with complex shapes, the piston can more easily spray the sound-absorbing paint to hard-to-reach areas to ensure full coverage. The uniform coating of the sound-absorbing paint can provide better sound absorption performance and reduce the noise generated when the fan blade 308 is in operation. The sound-absorbing paint can also provide a certain degree of protection to prevent the fan blade 308 from corrosion, wear or other damage.

[0055] Please refer to the above working process Figures 1 to 6 .

[0056] The following is the working process of the auxiliary cleaning mechanism cleaning the dust on the surface of the dustproof net 410:

[0057] During use, when the temperature sensor 2 detects that the temperature inside the graphics card body 1 is too high, the cylinder drives the electric telescopic rod 402 to extend, and the extension of the electric telescopic rod 402 drives the auxiliary frame 403 to move on the surface of the dustproof net 410. Due to the rotation and heat dissipation of the fan blades 308, a large amount of dust will adhere to the surface of the dustproof net 410, that is, the movement of the auxiliary frame 403 drives the third rotating column 404 rotatably connected to it to move together. Since the side of the graphics card body 1 close to the auxiliary frame 403 is fixedly connected with a rack 401, and the rack 401 is meshed with the first gear 405, that is, when the auxiliary frame 403 moves, the first gear 405 will rotate, and the rotation of the first gear 405 drives the third rotating column 404 fixedly connected to it to rotate, and the rotation of the third rotating column 404 drives the direction converter 406 fixedly connected to it to rotate, and the rotation of the direction converter 406 drives the cleaning roller 407 fixedly connected to it to rotate. Since the outer surface of the cleaning roller 407 is provided with a soft brush , that is, the surface of the dustproof net 410 is cleaned by rotating the cleaning roller 407. The cleaning roller 407 can quickly clean dust without disassembling the graphics card, saving time for disassembling and reinstalling the graphics card body 1. The user does not need to have professional skills and anyone can easily operate it. Manual disassembly of the graphics card body 1 may lead to some risks, such as electrostatic damage, connector damage or other accidental damage, and the use of the cleaning roller 407 can avoid these risks and protect the integrity of the graphics card body 1 and other hardware. The cleaning roller 407 can clean small gaps and hard-to-reach places, and can more effectively remove accumulated dust. Combined with the dust suction device, it can ensure that dust is no longer spread to other components and keep the internal environment clean. Regular use of the cleaning roller 407 can effectively prevent dust accumulation, thereby reducing the risk of overheating of the graphics card body 1 and other components, which can extend the service life of the equipment and reduce the performance degradation of the graphics card body 1 caused by overheating.

[0058] Since a dust suction device is provided inside the dust suction tube 408, and a dust suction hole is opened on the arc surface of the dust suction tube 408 near the cleaning roller 407, that is, when the cleaning roller 407 rotates to clean the dust, the dust suction device is started to absorb the dust swept by the cleaning roller 407. By collecting the flying dust, it is possible to avoid the dust from causing tiny dust pollution to the surrounding electronic equipment and affecting its performance, thereby reducing the secondary pollution to the equipment, which helps to maintain the efficiency and cleanliness of the cleaning operation. By effectively collecting the flying dust, the number of cleanings required can be reduced. By collecting the flying dust, the risk of dust splashing in some sensitive electronic equipment or precision instrument working areas, which may lead to safety problems such as short circuit and fire, can be reduced, thereby improving the safety of the working environment.
