Description

Technical Field

[0001] The invention relates to the technical field of cooling fans, in particular to a computer high-efficiency cooling fan based on centrifugal force diversion. Background Art

[0002] Computer cooling refers to the transfer of heat generated inside the computer through various means to prevent performance degradation or hardware damage caused by overheating. The main heat sources inside the computer include the CPU, motherboard, graphics card and other components. They consume electrical energy when working, and part of the electrical energy will be converted into heat. The main purpose of heat dissipation is to maintain these components within a safe operating temperature range. Common computer heat dissipation methods include: fan cooling, which uses a fan to blow air into the radiator to take away the heat. This method is simple and practical, but it may generate noise and dust accumulation and requires regular cleaning; heat sink cooling, which uses a large number of heat sinks to take away the heat. The advantages of this method are low noise and good heat dissipation effect, but the heat dissipation efficiency is limited by the area and number of heat sinks; water cooling, which uses a water pump to circulate the coolant through the radiator to take away the heat. This method has high heat dissipation efficiency and low noise, but the coolant needs to be replaced regularly, and the installation process is relatively complicated; air cooling, which uses heat dissipation components such as copper tubes and air to dissipate heat. This method is low in cost and easy to install, but the heat dissipation efficiency is low;

[0003] The most commonly used cooling methods are air cooling and water cooling. In the field of personal computer cooling, although air-cooled radiators have basically escaped the vicious circle of high-noise and violent cooling, they are generally developing in the direction of large volume, multiple heat pipes, and overweight. This brings great inconvenience to users in the actual use and installation of radiators, and also brings great challenges to the load-bearing and pressure-bearing capacity of computer accessories. As a mature cooling technology, liquid cooling has always been widely used in industrial applications, such as cooling of automobiles and aircraft engines. The application of liquid cooling technology in the computer field is not because air cooling has reached its end, but because the heat dissipation speed of liquid is much greater than that of air. Therefore, liquid cooling radiators often have good heat dissipation effects, and noise can also be well controlled. Due to its various advantages in heat dissipation efficiency and quietness, liquid cooling also appeared soon after computer air cooling became popular. Water cooling and air cooling are essentially the same, except that water cooling uses circulating liquid to move the heat of the CPU from the water cooling block to the radiator and then dissipate it, replacing the homogeneous metal or heat pipe of air cooling. The cooling The radiator part is almost a replica of the air-cooled radiator. The biggest features of the water-cooled heat dissipation system are two: balanced CPU heat and low-noise operation. Due to the large specific heat capacity of water, it can absorb a large amount of heat while keeping the temperature from changing significantly. The temperature of the CPU in the water-cooled system can be well controlled, and sudden operations will not cause a large instantaneous change in the internal temperature of the CPU. Due to the large surface area of ​​the heat exchanger, only a low-speed fan is needed to dissipate the heat to achieve a good effect. Therefore, water cooling is mostly equipped with a fan with a low speed. In addition, the working noise of the water pump is generally not very obvious, so the overall cooling system is very quiet compared to the air-cooled system. However, the heat dissipation efficiency of the radiator is related to the fin area of ​​the radiator. Under the condition of the same fin area, the heat dissipation effect can only be enhanced by increasing the speed of the cooling fan to drive the air flow faster or increasing the load. At the same time, the cold head has a large load when driving the heat transfer medium to flow quickly, and the pump body in the cold head must work continuously when the computer is in use. Long-term uninterrupted work plus a large load will reduce the service life of the water pump of the cold head, which is not conducive to the stable operation of the computer.

[0043] The piston plate 10 is connected to the heat-conducting blade 7 by sliding friction. The mounting groove 11 is located at the end of the piston plate 10 away from the central rotating column 6. The magnetic poles of the end of the magnetic block 12 facing the magnetic plate 22 are the same, and the magnetic plate 22 is of arc design.

At this time, when the water pump is started, the heat-conducting medium is injected into the radiator for heat dissipation, and then the radiator injects the heat-conducting medium into the absorption groove 19 through the insertion hole 23. At this time, the micro motor 5 on the mounting frame 4 drives the heat-conducting blade 7 and the mounting ring 14 to rotate at a high speed relative to the contact guide ring 15 through the ball 16 through the central rotating column 6. During the process, when the connecting hole 21 on the side of the mounting ring 14 rotates to the absorption groove 19 on the side surface of the contact guide ring 15, the heat-conducting medium in the absorption groove 19 is injected into the interior of the heat-conducting blade 7 through the connecting hole 21 The piston plate 10 is supported so that the piston plate 10 slides up and stretches the support spring 13.

During the process, the heat-conducting medium inside the heat-conducting blade 7 is accelerated to dissipate heat through the intense contact between the surface of the heat-conducting blade 7 and the air. The heat-conducting medium is conducted between the first installation frame 1, the second installation frame 2 and the third installation frame 3 by plugging the discharge pipe 18 into the insertion hole 23 until the heat-conducting medium flows back to the water-cooled water pump.

[0047] One end of the insertion hole 23 is mounted on the injection pipe 17, and the inner diameter of the insertion hole 23 is the same as the outer diameter of the discharge pipe 18. The limit column 25 is a T-shaped design with a larger upper part and a smaller lower part, and the cross section of the limit column 25 is a semicircular design. The limit ring 27 and the engaging groove 26 are concentrically designed, and the limit ring 27 is mounted on the opposite limit column 25 through the giving groove 28. The outer surface of the limit ring 27 is in contact with the inner surface of the engaging groove 26. The rotating rod 29 is a T-shaped design with a larger upper part and a smaller lower part, and the upper end side surface of the rotating rod 29 is a vertical plane design. The sliding groove 30 is a semi-annular design. The upper end of the rotating rod 29 passes through the sliding groove 30, and the upper end plane of the rotating rod 29 is in contact with the outer surface of the magnetic adsorption block 31.

[0048] When installing the first installation frame 1, the second installation frame 2 and the third installation frame 3, the discharge pipe 18 on one side of the third installation frame 3 is inserted into the insertion hole 23 on one side of the first installation frame 1, and then the discharge pipe 18 on one side of the first installation frame 1 is inserted into the insertion hole 23 on one side of the second installation frame 2 to complete the plug-in connection of the first installation frame 1, the second installation frame 2 and the third installation frame 3. At this time, the limit ring 27 in the engaging groove 26 engages with the limit column 25 through the yield groove 28, and then the rotating rod 29 is rotated, and the rotating rod 29 is separated from the adsorption of the magnetic adsorption block 31 on one side and slides in the sliding groove 30. At this time, the yield groove 28 rotates toward the connecting groove 24, and the rotating rod 29 is adsorbed on another magnetic adsorption block 31. At this time, the limit ring 27 engages with the limit column 25 to ensure stable installation.
