Description

Technical Field

[0001] The invention relates to the technical field of computer chip heat dissipation, and in particular to an air-cooled radiator capable of detecting a chip locking state. Background Art

[0002] As the core of an electronic computer, the CPU includes calculations and control, and its integration has become increasingly higher. The CPU is responsible for reading instructions, decoding instructions and executing instructions for all operations in the computer. With the advancement of scientific and technological research and development, this core component has grown into a core area with highly concentrated heat and high temperature. In addition, a large number of DIY players or friends who love hardware like to overclock, but the better the overclocking effect, the greater the temperature and heat of the CPU. Therefore, cooling the CPU is an essential hardware for normal use of the computer and overclocking. It is indispensable. As the CPU integration becomes denser and higher, cooling the CPU is also a trend that must be done.

[0003] CPU radiators can be divided into air-cooled radiators, heat pipe radiators, water-cooled radiators and other products. The most mainstream CPU radiators in the world are air-cooled radiators and heat pipe radiators, which are recognized and purchased by consumers because of their affordable prices, excellent performance and high quality. Among them, the two types of products, air-cooled radiators and heat pipe radiators, have been integrated at the mid-to-high-end level.

[0004] The heat dissipation method of the air-cooled radiator is to place a heat sink with good thermal conductivity against the CPU chip, and then use a fan to blow or extract the temperature on the heat sink. This method ensures that the temperature of the heat sink is always at a low temperature, so that the CPU chip is continuously cooled;

[0005] In actual production, it is inevitable that the screws of the radiator will be missed or not locked in place. It is also possible that during operation, the long-term rotation and vibration of the fan will cause the bolts locking the radiator to loosen, which will cause a gap between the radiator and the chip. In the short term, there will be almost no problems with this situation, but there is still a great risk in long-term use. The gap will prevent the chip from contacting the heat sink, greatly reducing the heat dissipation effect. Air is a very poor thermal conductor. The air gap between the radiator and the chip will cause poor contact between the main chip and the radiator, which will affect the contact thermal resistance between the main chip and the radiator, causing the main chip temperature to be too high, affecting product performance and safety.

[0006] Based on this, the present invention designs an air-cooled heat sink capable of detecting the locking state of a chip to solve the above-mentioned problem. Summary of the invention

[0007] The purpose of the present invention is to provide an air-cooled radiator that can detect the locking state of a chip. It can monitor whether the radiator of a computer is fitted to the chip at all times without disassembling the computer, and can timely lock the radiator and chip where a gap is generated, ensuring that the radiator and the chip are in a tight fit, thereby ensuring that the radiator has the best heat dissipation effect on the chip.

[0008] The present invention is implemented as follows: an air-cooled heat sink capable of detecting the locking state of a chip comprises a fan and a bottom plate, wherein a limiting groove is provided on the bottom plate, and the limiting groove is located directly below the blades of the fan;

[0009] A locking bolt, which is detachably installed and fastened in the limiting groove;

[0010] A spring, wherein the spring is arranged between the locking bolt and the limiting groove;

[0011] The top of the locking bolt tightly installed in the limiting groove does not contact the blades of the fan.

[0012] Furthermore, an anti-damage soft cover is fixed to the top of the locking bolt, and the anti-damage soft cover is an annular integral structure made of rubber.

[0013] Furthermore, there is a height gap H between the installed anti-damage soft cover of the locking bolt and the blades of the fan, and the distance of the gap H does not exceed 0.8 mm.

[0014] Furthermore, the fan is a CPU fan with rotation speed monitoring.

[0015] Furthermore, the spring is a compression spring.

[0016] The beneficial effect of the present invention is as follows: the present invention arranges the locking bolt under the blades of the fan, and the gap between the anti-damage soft cover on the top of the locking bolt and the blades is no more than 0.8 mm. Therefore, as long as the locking bolt is not locked in place, the locking bolt will block the rotation of the blades, the fan will stop working, and the heat dissipation effect of the radiator will be sharply reduced. Therefore, the fan speed and the actual operating temperature of the CPU can be easily checked from the computer operating software. As long as the fan speed decreases and the CPU temperature increases, it means that a gap is generated between the radiator and the chip. Therefore, the device can check at any time whether the radiator is in close contact with the chip and whether the radiator is in the best heat dissipation state without disassembling the chassis for inspection.

[0024] See also Figures 1 to 4 As shown, the present invention provides a technical solution: an air-cooled heat sink capable of detecting the locking state of a chip, comprising a fan 3 and a bottom plate 5, wherein a limiting groove 4 is provided on the bottom plate 5, and the limiting groove 4 is located directly below the blade 31 of the fan 3;

[0025] A locking bolt 1, which is detachably installed and fastened in the limiting groove 4;

[0026] A spring 2, wherein the spring 2 is arranged between the locking bolt 1 and the limiting groove 4;

[0027] The top of the locking bolt 1 tightly installed in the limit groove 4 does not contact the blade 31 of the fan 3, so that the computer's radiator and chip fit can be monitored at all times without disassembling the computer, and the radiator and chip with a gap can be locked in time to ensure that the radiator and the chip are in a tight fit, so as to ensure that the radiator has the best heat dissipation effect on the chip.

[0028] Among them, an anti-damage soft cover 11 is fixed on the top of the locking bolt 1. The anti-damage soft cover 11 is an annular integral structure made of rubber. The anti-damage soft cover 11 can stop or slow down the fan 3 without causing damage to the blades 31 due to hard collision;

[0029] There is a height gap H between the anti-damage soft cover 11 of the locking bolt 1 and the blade 31 of the fan 3 after installation. The distance of the gap H does not exceed 0.8 mm. This distance can be adjusted to ensure that the blade 31 rotates normally when dissipating heat, and can react immediately when a small gap is generated between the chip and the heat sink 51.

[0030] Fan 3 is a CPU fan with speed monitoring, which is a commonly used device and has the same function as the fan 3 of the chip radiator of the computer;

[0031] The spring 2 is a compression spring, which ensures that the locking bolt 1 can always press the chip between the base plate 5 and the heat sink 51, and can ensure that the locking bolt 1 rises and presses against the blade 31 when loose.

[0032] In a specific embodiment of the present invention:

[0033] The present invention encounters the technical problem that the radiator and the CPU chip of the computer are not locked tightly, resulting in a gap between the radiator and the chip, which makes it difficult for the chip to dissipate heat, and it is difficult to find out what the cause is; the technical means adopted are: the spring 2 will always support the locking bolt 1, once any locking bolt 1 of the radiator is not locked tightly or loose, the spring 2 will support the locking bolt 1 to hold the blade 31 of the fan 3, the speed of the fan 3 will be immediately reduced, and the heat dissipation effect will also drop sharply. Through the software on the computer, it is easy to see that the speed of the fan 3 is abnormal, and the machine can be disassembled in time to lock the radiator tightly; this technical means follows the principle of reducing the speed of the fan 3 and dissipating When the thermal effect is reduced, it means that there is a problem with the fan. It is very likely that there is a gap between the radiator and the chip, resulting in poor heat dissipation. This information could not be obtained before. Now, through the blocking of the locking bolt 1, the operation status of the radiator can be checked at any time; it is possible to check in time whether the radiator and the chip are installed tightly, and there is no need to disassemble the machine to check, nor to measure with a measuring tool, and there is no need to shut down the computer to check whether there is a gap between the radiator and the chip. If a gap occurs, the locking bolt 1 of the radiator can be calibrated and locked in time to prevent the chip from working in a state of poor heat dissipation for a long time. The technical effects are as follows:

[0034] The embodiment of the present invention provides an air-cooled heat sink capable of detecting the locking state of a chip. The technical problems solved by the present invention are as follows: 1. When the computer is running, the fan 3 of the CPU runs for a long time, generating rotation and vibration, which may cause the locking bolt 1 that fixes the heat sink and the chip to be loosened. When the locking bolt 1 is loosened, an air gap is generated between the chip and the heat sink. This gap makes it difficult for the heat emitted by the chip to be transferred to the heat sink, causing the heat to accumulate at the chip. In this way, the chip works in a hot state for a long time, which may cause the chip to run unsmoothly and cause the computer to freeze; 2. The original locking bolt 1 is loose, which may cause the chip to run unsmoothly and cause the computer to freeze. For the convenience of installation, the bolt 1 is installed at a position that does not interfere with the blade 31 of the fan 3. Generally, there is a locking bolt 1 at each of the four corners of the radiator, and the locking bolt 1 will not block the blade 31 when it is raised; 3. Under the action of gravity, the locking bolt 1 will not rise even if it is loose, so there is still a gap between the chip and the radiator, but the locking bolt 1 will not block the blade 31, and at present, many radiators do not use practical bolts but use a buckle structure, which is easy to install, but the assembly is more loose, and it is easy to produce a gap between the radiator and the chip, resulting in poor heat dissipation effect of the chip;

[0035] The technical effects achieved are as follows: 1. Without disassembling the machine, the blades 31 of the fan 3 can be prevented from rotating normally by loosening the locking bolt 1, so that if the rotation speed of the fan 3 is abnormal, the gap between the heat sink and the chip can be found in time;

[0036] 2. When the blades 31 are blocked, the soft anti-damage cover 11 is used to block them, which will not damage the blades 31 and can slow down or stop the fan 3;

[0037] 3. The locking bolts 1 are used to continuously tighten the bottom plate 5 and the heat sink 51 of the radiator through the spring 2, and the chip is installed in the gap between the heat sink 51 and the bottom plate 5. That is, the locking bolts 1 are kept in a tight working state through the spring 2, and once any locking bolt 1 is loosened, the loosened locking bolt 1 will rise to support the blade 31. At the same time, even if the locking bolt 1 is loosened, the heat sink 51 and the bottom plate 5 will be tightly pulled together under the elastic force of the spring 2, ensuring that the chip fits tightly with the radiator to ensure the heat dissipation effect.

[0038] The technical solution in the embodiment of the present invention is to solve the above problems, and the overall idea is as follows:

[0039] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] During installation, the chip is placed between the bottom plate 5 and the heat sink 51 of the heat sink, and then a plurality of locking bolts 1 are installed just below the blades of the heat sink fan 3, such as Figure 2As shown, this embodiment installs 4 pieces instead of using a snap-on installation method. At the same time, a spring 2 is set on the outside of each locking bolt 1, and one end of the spring 2 is against the limiting groove 4 of the bottom plate 5, and the other end of the spring 2 is against the top of the locking bolt 1, ensuring that the locking bolt 1 and the limiting groove 4 compress the spring 2, and then each locking bolt 1 is tightened. At this time, the installed spring 2 is already in a compressed and tight state. In this state, as long as the locking bolt 1 is loosened, it will be lifted up by the spring 2 to block the rotation of the blade 31, and the speed of the fan 3 will be reduced. Although the locking bolt 1 is raised, at this time, under the elastic force of the spring 2, the chip and the heat sink 51 will fit tightly together, and the speed of the fan 3 will be reduced or stopped, which can be cleared through Master Lu or similar computer software. The real-time rotation speed of the fan 3 can be clearly checked, and it is easy to judge whether the locking bolt 1 is loose. If there is only the spring 2, it cannot completely ensure that the chip and the heat sink 51 are tightly fitted for a long time. Because the height difference H between the anti-damage soft cover 11 and the blade 31 of the device does not exceed 0.8mm, as long as the locking bolt 1 is loosened by more than 0.8mm of the vertical distance, the fan 3 will be immediately blocked and react. The user can immediately understand the fit between the chip and the radiator and react quickly without disassembling the machine or shutting down the computer. It can be checked in real time to ensure that the computer chip and the radiator are always in a tightly fitted state, ensuring the best heat dissipation effect of the chip, avoiding continuous heating of the chip due to the gap, and making the chip run to achieve the best computing effect.

[0041] And when the gap is small, the blades of fan 3 are not completely blocked by the anti-damage soft cover 11 of the locking bolt 1, and can still rotate but slow down. At this time, the fan can easily hear the sound of the blades 31 of fan 3 hitting the anti-damage soft cover 11. When the gap is large, the anti-damage soft cover 11 of the locking bolt 1 will completely block the rotation of fan 3. At this time, fan 3 is completely silent, and it is easy to judge the rotation of fan 3. It can be known that there is a large gap between the radiator and the chip. The locking bolt 1 has been extended for a long distance, at least exceeding the actual gap H distance, which is generally 0.8mm, blocking the rotation of fan 3. And through the computer status running software such as Master Lu, it can be checked that the speed of the computer's CPU fan 3 is 0, and the gap between the radiator and the chip can also be judged.

[0042] The use steps are as follows: Step 1, install the chip on the bottom plate 5 of the radiator;

[0043] Step 2, pass the locking bolt 1 through the blade 31 of the fan 3, and press and install the spring 2 on the limiting groove 4 through the locking bolt 1;

[0044] Step 3, tighten the locking bolt 1, press the chip onto the base plate 5, and make the heat sink fit tightly to the chip;

[0045] Step 4, if the speed of fan 3 is normal when running, the locking bolt 1 is not loose, and the blades 31 of fan 3 are not blocked from rotating; if the speed of fan 3 is abnormal when running, it means that the locking bolt 1 may have been loosened and pushed upward by the spring 2. The locking bolt 1 is directly below the fan 3, and the gap is less than 0.8 mm. Therefore, as long as the locking bolt 1 is slightly loosened and raised, the blades 31 of fan 3 will be blocked from rotating, so that the rotation of fan 3 is blocked and the speed is reduced. At the same time, through computer software, such as Master Lu, it can be detected that the temperature of the CPU increases and the speed of fan 3 decreases. At this time, it means that the tightening bolt 1 has loosened and risen and needs to be tightened. Then disassemble the computer case and tighten the locking bolt 1 of the radiator. The speed of fan 3 can be detected at any time through this device, and then it can be found whether the radiator is loose from the chip, so as to avoid the gap between the chip and the radiator, effectively avoid poor heat dissipation of the chip, and overheating of the chip will affect the performance of the computer. The device can monitor whether the chip fits the radiator at any time through the computer.
