Description

Technical Field

[0001] This invention relates to the field of cooling fan technology, specifically to a high-efficiency computer cooling fan based on centrifugal force flow guidance. Background Technology

[0002] Computer cooling refers to the process of removing heat generated inside a computer through various means to prevent overheating that could lead to performance degradation or hardware damage. The main heat sources inside a computer include the CPU, motherboard, graphics card, and other components. These components consume electrical energy during operation, some of which is converted into heat. The primary purpose of cooling is to maintain these components within a safe operating temperature range. Common computer cooling methods include: fan cooling, which uses a fan to blow air into the heatsink to remove heat; this method is simple and practical, but may generate noise and dust, requiring regular cleaning; fin cooling, which uses numerous heatsinks to remove heat; this method has the advantages of low noise and good cooling effect, but its efficiency is limited by the area and number of heatsinks; water cooling, which uses a water pump to circulate coolant through the heatsink to remove heat; this method has high cooling efficiency and low noise, but requires regular coolant replacement and has a relatively complex installation process; and air cooling, which uses heat dissipation components such as copper pipes to dissipate heat through the air; this method is inexpensive and easy to install, but its cooling efficiency is relatively low.

[0003] The most common heat dissipation methods are air cooling and liquid cooling. In the field of personal computer cooling, although air cooling has largely escaped the vicious cycle of high noise and violent heat dissipation, it has generally developed towards larger size, more heat pipes, and greater weight. This brings great inconvenience to users in terms of actual use and installation, and also puts a great test on the load-bearing capacity of computer components. As a mature cooling technology, liquid cooling has long been widely used in industrial applications, such as automobile and aircraft engine cooling. The application of liquid cooling technology to the computer field is not because air cooling has reached its limit, but because the heat dissipation rate of liquid is much greater than that of air. Therefore, liquid cooling radiators often have good heat dissipation effect, and the noise level is also well controlled. Due to its advantages in heat dissipation efficiency and quietness, liquid cooling emerged shortly after air cooling became popular in computers. Liquid cooling and air cooling are essentially the same, except that liquid cooling uses circulating fluid to transfer the heat of the CPU from the water cooling block to the radiator and then dissipate it, replacing the homogeneous metal or heat pipes of air cooling. The radiator section is almost a carbon copy of an air cooler. The biggest advantages of a water cooling system are twofold: balanced heat distribution on the CPU and low noise operation. Due to water's extremely high specific heat capacity, it can absorb a large amount of heat while maintaining a relatively stable temperature. In a water cooling system, the CPU temperature can be well controlled, and sudden operations will not cause a sudden and drastic change in the CPU's internal temperature. Because the heat exchanger has a large surface area, only low-speed fans are needed for effective cooling. Therefore, water cooling systems are mostly equipped with low-speed fans. In addition, the operating noise of the water pump is generally not very noticeable. Thus, the overall cooling system is much quieter than an air cooling system. However, the cooling efficiency of a radiator is related to the fin area. With the same fin area, the only ways to improve cooling are to increase the fan speed to drive airflow or to increase the water load. At the same time, the water block bears a heavy load when rapidly moving the heat transfer medium, and the pump in the water block must work continuously during computer use. Prolonged continuous operation under a heavy load will reduce the lifespan of the water pump in the water block, which is detrimental to the stable operation of the computer.

[0039] 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.

[0040] Please see Figure 1-10 This invention provides a technical solution: a high-efficiency computer cooling fan based on centrifugal force flow guidance, comprising a first mounting frame 1, a second mounting frame 2 and a third mounting frame 3 respectively arranged on both sides of the first mounting frame 1, and a mounting bracket 4 fixedly arranged on the lower inner surface of the first mounting frame 1, the second mounting frame 2 and the third mounting frame 3, and a micro motor 5 fixedly mounted in the center of the mounting bracket 4, a central rotating column 6 fixedly mounted on the upper end of the output shaft of the micro motor 5, and heat-conducting blades 7 fixedly arranged on the side surface of the central rotating column 6. A flow guiding mechanism is arranged on the inner side of the first mounting frame 1, the second mounting frame 2 and the third mounting frame 3, and the centrifugal force of the rotation of the heat-conducting blades 7 causes the heat-conducting medium to pass through the heat-conducting blades 7 for rapid heat dissipation.

[0041] The flow guiding mechanism includes: a sealing plate 8, which is snapped onto the upper surface of the heat-conducting blade 7, and the heat-conducting blade 7 is hollow. A pressure relief hole 9 is provided on the outer surface of the sealing plate 8. A piston plate 10 is provided on the inner surface of the heat-conducting blade 7, and an installation groove 11 is provided on the upper surface of the piston plate 10. A magnetic block 12 is fixedly installed inside the installation groove 11. A support spring 13 is connected between the lower surface of the piston plate 10 and the inner bottom surface of the heat-conducting blade 7. An installation ring 14 is fixedly installed on the outer surface of the heat-conducting blade 7.

[0042] The flow guiding mechanism also includes: a contact guide ring 15, which is embedded in the inner surface of the first mounting frame 1, the second mounting frame 2, and the third mounting frame 3; a rotating ball bearing 16 is provided at the connection between the mounting ring 14 and the contact guide ring 15; an injection pipe 17 is provided on one side surface of the contact guide ring 15, and a discharge pipe 18 is provided on the other side surface of the contact guide ring 15; an absorption groove 19 is provided on the inner surface of the end of the contact guide ring 15 where the injection pipe 17 is provided; a discharge groove 20 is provided on the inner surface of the end of the contact guide ring 15 where the discharge pipe 18 is provided; a connecting hole 21 is provided on the side surface of the mounting ring 14; and a magnetic plate 22 is fixedly provided on the inner surface of the first mounting frame 1, the second mounting frame 2, and the third mounting frame 3.

[0043] The piston plate 10 and the heat-conducting blade 7 are connected 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 magnetic block 12 and the magnetic plate 22 are the same at the opposite ends. The magnetic plate 22 is arc-shaped. The mounting ring 14 and the contact guide ring 15 are concentrically arranged. One end of the injection pipe 17 is connected to the absorption groove 19. The discharge pipe 18 passes through the outer surfaces of the first mounting frame 1, the second mounting frame 2 and the third mounting frame 3. One end of the discharge pipe 18 is connected to the discharge groove 20. The discharge groove 20 is arc-shaped. The two ends of the connecting hole 21 pass through the inner and outer surfaces of the mounting ring 14 respectively.

[0044] In use, first connect the output hose of the radiator to the insertion hole 23 on one side of the third mounting frame 3 and connect it to the injection pipe 17. Then, connect the discharge pipe 18 on one side of the second mounting frame 2 to the input end of the water pump through the hose. When the water pump starts, it injects the heat transfer medium into the radiator for heat dissipation. Then, the radiator injects the heat transfer medium into the absorption groove 19 through the insertion hole 23. At this time, the micro motor 5 on the mounting bracket 4 drives the heat transfer blades 7 and the mounting ring 14 to rotate at high speed relative to the guide ring 15 through the ball bearings 16 via 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 guide ring 15, the heat transfer medium in the absorption groove 19 is injected into the interior of the heat transfer blades 7 through the connecting hole 21. The piston plate 10 is supported so that it slides up and stretches the support spring 13. The pressure relief hole 9 on the sealing plate 8 is responsible for eliminating the pressure difference generated by the sliding of the piston plate 10. When the connecting hole 21 rotates to the discharge groove 20, under the centrifugal force and the repulsive action of the magnetic plate 22 on the magnetic block 12 in the mounting groove 11, the heat conduction medium inside the heat conduction blade 7 is discharged through the discharge groove 20 and the discharge pipe 18. During the process, the heat conduction medium inside the heat conduction blade 7 accelerates heat dissipation through the intense contact between the surface of the heat conduction blade 7 and the air. The heat conduction medium is conducted between the first mounting frame 1, the second mounting frame 2 and the third mounting frame 3 through the insertion of the discharge pipe 18 and the insertion hole 23 until the heat conduction medium flows back to the water-cooled water pump.

[0045] The upper side surfaces of the first mounting frame 1, the second mounting frame 2, and the third mounting frame 3 are provided with plug-in mechanisms, which ensure the normal flow of the heat transfer medium by connecting the first mounting frame 1, the second mounting frame 2, and the third mounting frame 3 in pairs.

[0046] The insertion mechanism includes: an insertion hole 23, which is opened on one end side surface of the first mounting frame 1, the second mounting frame 2, and the third mounting frame 3; a connecting groove 24 is provided on the upper surface of the first mounting frame 1 and the second mounting frame 2 at the end where the insertion hole 23 is opened; a limiting post 25 is fixedly provided inside the connecting groove 24; a locking groove 26 is opened on the upper surface of the first mounting frame 1 and the third mounting frame 3 facing the second mounting frame 2; a rotating limiting ring 27 is installed inside the locking groove 26; a clearance groove 28 is opened on one end of the limiting ring 27; a rotating rod 29 is fixedly provided on the upper surface of the limiting ring 27; a sliding groove 30 is opened on the upper surface of the first mounting frame 1 and the third mounting frame 3 above the clearance groove 28; and magnetic adsorption blocks 31 are fixedly provided at both ends of the sliding groove 30.

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

[0048] When installing the first mounting frame 1, the second mounting frame 2, and the third mounting frame 3, insert the drain pipe 18 on one side of the third mounting frame 3 into the insertion hole 23 on one side of the first mounting frame 1, and then insert the drain pipe 18 on one side of the first mounting frame 1 into the insertion hole 23 on one side of the second mounting frame 2, thus completing the connection of the first mounting frame 1, the second mounting frame 2, and the third mounting frame 3. At this time, the limiting ring 27 in the engaging groove 26 engages with the limiting post 25 through the clearance groove 28. Then, rotate the rotating rod 29, and the rotating rod 29 disengages from the magnetic adsorption block 31 on one side and slides in the sliding groove 30. At this time, the clearance groove 28 rotates towards the connecting groove 24, while the rotating rod 29 adheres to and is adsorbed by another magnetic adsorption block 31. At this time, the limiting ring 27 engages with the limiting post 25, making it impossible for the first mounting frame 1, the second mounting frame 2, and the third mounting frame 3 to separate, thus ensuring stable installation.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
