Description

Technical Field

[0001] The utility model relates to the technical field of graphics card heat dissipation, and specifically relates to a low-noise graphics card heat dissipation device. Background Technique

[0002] The graphics card is an important component of a personal computer. During the normal use of the computer, the graphics card is responsible for the correct display of the monitor. During this process, the load on the graphics card is often large and a large amount of heat is generated. Therefore, the heat dissipation of the graphics card has always been a topic of research.

[0003] Existing graphics cards generally use fans for heat dissipation, and usually install two or more fans. In some high-load working conditions, the rotation speed of the fans will increase accordingly. Although the heat dissipation effect is good, it will generate relatively large noise and affect our working state.

[0004] In view of the problem of noise generated by the above-mentioned heat dissipation, a method of active noise reduction by using temperature reduction compensation and sound insulation is designed to overcome the above-mentioned problems. Content of the Utility Model

[0005] In order to overcome the problem of noise generated by the existing graphics card heat dissipation.

[0006] The technical solution of the utility model is: a low-noise graphics card heat dissipation device, which includes a graphics card main body, a side plate and an interface; it also includes a turbo fan, a temperature sensor and a control switch. One side of the graphics card main body is fixedly installed with a side plate, and there is an air outlet for ventilation and heat dissipation on one side of the side plate. There is an interface for connecting to the host on one side of the side plate. A turbo fan is installed on the graphics card main body. A temperature sensor is fixedly installed on one side of the side plate, and the sensing end of the temperature sensor is arranged at the air outlet of the side plate. A control switch for controlling the rotation speed of the turbo fan is fixedly installed on one side of the side plate, and one end of the control switch is connected to the temperature sensor through a circuit. A water-cooled auxiliary heat dissipation mechanism is provided on the graphics card main body, and a disassembly and assembly mechanism for realizing quick disassembly and assembly by magnetic adsorption is provided on one side of the graphics card main body.

[0007] Preferably, the hot air in the graphics card is discharged from the ventilation opening on the side plate. The temperature sensor senses the temperature of the hot air in real time. When the temperature is too high, the control switch receives the electrical signal transmitted by the temperature sensor and increases the rotation speed of the turbo fan. When the temperature of the graphics card is too high, the auxiliary heat dissipation mechanism reduces the temperature inside the graphics card main body, avoiding the noise caused by the high-speed rotation of the turbo fan. The coolant has a sound insulation effect, avoiding noise while ensuring the heat dissipation effect. The disassembly and assembly mechanism facilitates the installation and disassembly of the auxiliary heat dissipation mechanism. Compared with the traditional bolt installation, this mechanism can be quickly disassembled, facilitating the maintenance of the auxiliary heat dissipation mechanism.

[0008] Preferably, the auxiliary heat dissipation mechanism includes a liquid storage tank, a diversion pipe, a condensation pipe, a connecting plate, an outer frame, heat sinks, and a circulation pump. A liquid storage tank is slidably connected to the graphics card body. One side of the liquid storage tank is fixed with a diversion pipe, and a condensation pipe is fixedly arranged on the diversion pipe. One side of the liquid storage tank is fixedly connected with a connecting plate, and an outer frame is fixedly connected to the connecting plate through bolts. Heat sinks are fixedly connected to the outer frame. A circulation pump is fixedly connected to the upper end of the graphics card body. When the turbine fan works, the hot air in the graphics card is discharged from the ventilation openings on the side plate. The temperature sensor continuously senses the temperature of the hot air. When the temperature is too high, the control switch receives the electrical signal transmitted by the temperature sensor and increases the rotation speed of the turbine fan. At this time, the circulation pump is started simultaneously. The coolant in the liquid storage tank enters the condensation pipe through the diversion pipe under the action of the circulation pump. The air flow blown by the turbine fan further cools the coolant in the condensation pipe, and the heat sinks enable the heat to be quickly dissipated, enhancing the heat dissipation performance.

[0009] Preferably, the liquid storage tank is adapted to the graphics card body, and the inner wall of the liquid storage tank is in contact with the surface of the graphics card body. The condensation pipes are arranged on both sides above the turbine fan. The adaptation of the liquid storage tank to the graphics card body facilitates the coolant in the liquid storage tank to absorb the heat in the graphics card. The arrangement of the condensation pipes on both sides above the turbine fan ensures the full utilization of the air flow for heat dissipation and does not affect ventilation.

[0010] Preferably, the outer frame is provided with grooves for engaging with the diversion pipe, and the heat sinks are provided with grooves for engaging with the diversion pipe and the condensation pipe. The engagement of the groove of the outer frame with the diversion pipe can achieve the quick positioning of the outer frame, facilitating the connection between the outer frame and the liquid storage tank. The engagement of the grooves of the heat sinks with the diversion pipe and the condensation pipe ensures full contact of the heat sinks, ensuring the heat dissipation effect.

[0011] Preferably, the disassembly and assembly mechanism includes a support frame, a handle, a clamping block, a magnetic strip, and a clamping groove. A support frame is fixedly installed on one side of the liquid storage tank. A handle is fixed on one side of the support frame, and a clamping block is fixedly connected to the other side of the support frame. A magnetic strip is fixedly connected to the end of the clamping block. A clamping groove adapted to the clamping block is provided on one side of the graphics card body. The groove on the outer frame is engaged with the diversion pipe, and then the connecting plate and the outer frame are fixed together with bolts, thus completing the preliminary installation of the auxiliary heat dissipation mechanism. Subsequently, the handle on the support frame is lifted, and the liquid storage tank is assembled in adaptation with the graphics card body. The clamping block is adapted to the clamping groove, and the magnetic strip at one end of the clamping block is adsorbed on one side of the graphics card body, thereby completing the fixation of the auxiliary heat dissipation mechanism.

[0012] Preferably, there is a distance between the bottom surface of the support frame and the end of the graphics card body. A recess is provided on one side of the graphics card body. The distance between the bottom surface of the support frame and the end of the graphics card body facilitates putting the hand into the recess of the graphics card body, facilitating the release of the adsorption between the clamping block and the clamping groove.

[0013] Preferably, a shock pad is provided in the card slot, and the shock pad in the card slot is laid on the four walls of the card slot. Laying the shock pad on the four walls of the card slot ensures the tightness between the card block and the card slot, and ensures that no abnormal noise will be generated due to the gap during the operation of the graphics card.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. When the temperature of the graphics card is too high, the auxiliary heat dissipation mechanism drives the coolant through the circulation pump, and uses the turbine fan and the condensation pipe to accelerate the cooling of the coolant, so that the temperature in the graphics card body drops. In this way, the noise caused by the high-speed rotation of the turbine fan is avoided, and the coolant in the liquid storage chamber has a sound insulation effect, avoiding noise while ensuring the heat dissipation effect.

[0016] 2. The disassembly and assembly mechanism facilitates the installation and disassembly of the auxiliary heat dissipation mechanism. Compared with the traditional bolt installation, this mechanism can be quickly disassembled, facilitating the maintenance of the auxiliary heat dissipation mechanism. Description of the Drawings

The hot air in the graphics card is discharged from the ventilation opening on the side plate 2. The temperature sensor 5 senses the temperature of the hot air in real time. When the temperature is too high, the control switch 6 receives the electrical signal transmitted by the temperature sensor 5 and increases the rotation speed of the turbo fan 4. When the temperature of the graphics card is too high, the auxiliary heat dissipation mechanism reduces the temperature in the graphics card main body 1, avoiding the noise caused by the high-speed rotation of the turbo fan 4. The coolant has a sound insulation effect, avoiding noise while ensuring the heat dissipation effect. The disassembly and assembly mechanism facilitates the installation and disassembly of the auxiliary heat dissipation mechanism. Compared with the traditional bolt installation, this mechanism can be quickly disassembled, facilitating the maintenance of the auxiliary heat dissipation mechanism.

The liquid storage tank 7 is adapted to the graphics card main body 1, and the inner wall of the liquid storage tank 7 is in contact with the surface of the graphics card main body 1. The condensation pipe 9 is arranged on both sides above the turbo fan 4. The outer frame 11 is provided with a groove for engaging with the diversion pipe 8, and the heat sinks 12 are provided with grooves for engaging with the diversion pipe 8 and the condensation pipe 9. When the turbo fan 4 works, the hot air in the graphics card is discharged from the ventilation openings on the side plate 2. The temperature sensor 5 senses the temperature of the hot air in real time. When the temperature is too high, the control switch 6 receives the electrical signal transmitted by the temperature sensor 5 and increases the rotation speed of the turbo fan 4. At this time, the circulation pump 18 is started simultaneously. The coolant in the liquid storage tank 7 enters the condensation pipe 9 through the diversion pipe 8 under the action of the circulation pump 18.

The adaptation of the liquid storage tank 7 to the graphics card main body 1 facilitates the coolant in the liquid storage tank 7 to absorb the heat in the graphics card. The arrangement of the condensation pipe 9 on both sides above the turbo fan 4 ensures full utilization of the airflow for heat dissipation and does not affect ventilation. The engagement of the groove of the outer frame 11 with the diversion pipe 8 can achieve the quick positioning of the outer frame 11, facilitating the connection between the outer frame 11 and the liquid storage tank 7. The engagement of the grooves of the heat sinks 12 with the diversion pipe 8 and the condensation pipe 9 ensures full contact of the heat sinks 12, ensuring the heat dissipation effect.

[0028] Please refer to Figures 4-7, in this embodiment, the disassembly and assembly mechanism includes a support frame 13, a handle 14, a clamping block 15, a magnetic strip 16 and a clamping groove 17. A support frame 13 is fixedly installed on one side of the liquid storage chamber 7. A handle 14 is fixed on one side of the support frame 13. The other side of the support frame 13 is fixedly connected to a clamping block 15. A magnetic strip 16 is fixedly connected to the end of the clamping block 15. A clamping groove 17 adapted to the clamping block 15 is provided on one side of the graphics card main body 1. There is a certain distance between the bottom surface of the support frame 13 and the end of the graphics card main body 1. A recess is provided on one side of the graphics card main body 1. A shock pad is arranged in the clamping groove 17, and the shock pad in the clamping groove 17 is laid on the four walls of the clamping groove 17. The groove on the outer frame 11 is engaged with the diversion pipe 8, and then the connecting plate 10 and the outer frame 11 are fixed together with bolts, thus completing the preliminary installation of the auxiliary heat dissipation mechanism. Then, the handle 14 on the support frame 13 is lifted, and the liquid storage chamber 7 is assembled with the graphics card main body 1 in a matching manner. The clamping block 15 is adapted to the clamping groove 17, and the magnetic strip 16 at one end of the clamping block 15 is adsorbed on one side of the graphics card main body 1, thereby completing the fixation of the auxiliary heat dissipation mechanism. The distance between the bottom surface of the support frame 13 and the end of the graphics card main body 1 facilitates putting the hand into the recess of the graphics card main body 1, which is convenient for releasing the adsorption between the clamping block 15 and the clamping groove 17. The shock pad is laid on the four walls of the clamping groove 17 to ensure the tightness between the clamping block 15 and the clamping groove 17, ensuring that no abnormal noise will be generated due to the gap during the operation of the graphics card.

[0029] During use, before using the graphics card, the groove on the outer frame 11 is engaged with the diversion pipe 8, and then the connecting plate 10 and the outer frame 11 are fixed together with bolts, thus completing the preliminary installation of the auxiliary heat dissipation mechanism. Then, the handle 14 on the support frame 13 is lifted, and the liquid storage chamber 7 is assembled with the graphics card main body 1 in a matching manner. The clamping block 15 is adapted to the clamping groove 17, and the magnetic strip 16 at one end of the clamping block 15 is adsorbed on one side of the graphics card main body 1, thereby completing the fixation of the auxiliary heat dissipation mechanism. During the operation of the graphics card, the turbine fan 4 operates, and the hot air in the graphics card is discharged from the ventilation openings on the side plate 2. The temperature sensor 5 senses the temperature of the hot air in real time. When the temperature is too high, the control switch 6 receives the electrical signal transmitted by the temperature sensor 5 and increases the rotation speed of the turbine fan 4. At this time, the circulation pump 18 is started simultaneously. The coolant in the liquid storage chamber 7 enters the condensation pipe 9 through the diversion pipe 8 under the action of the circulation pump 18. The airflow blown by the turbine fan 4 further cools the coolant in the condensation pipe 9. The heat sink 12 enables the heat to be quickly dissipated, enhancing the heat dissipation performance. In this way, the temperature inside the graphics card main body can be decreased, thereby reducing the rotation speed of the turbine fan 4. The coolant in the liquid storage chamber 7 has a certain sound insulation effect, so active noise reduction can be achieved. When the auxiliary heat dissipation mechanism needs to be disassembled for maintenance, press the groove on one side of the graphics card main body 1 with one hand, hold the handle 14 with the other hand, and pull the handle 14 outwards to release the adsorption between the clamping block 15 and the clamping groove 17.

[0030] Through the above steps, when the temperature of the graphics card is too high, the auxiliary heat dissipation mechanism drives the coolant through the circulation pump 18, and uses the turbine fan 4 and the condenser tube 9 to accelerate the cooling of the coolant, thereby reducing the temperature inside the graphics card main body 1. This avoids the noise caused by the high-speed rotation of the turbine fan 4, and the sound insulation effect of the coolant in the liquid storage tank 7 avoids noise while ensuring the heat dissipation effect.
