Description

Anti-vibration mechanism for heat sink

technical field

The utility model relates to an anti-vibration mechanism of a heat dissipation device, in particular to an anti-vibration mechanism for eliminating the vibration generated by the heat dissipation device during operation.

Background technique

The mainframe of the computer is equipped with major devices such as the motherboard, CPU, various disk drives, and power supplies. The components that mainly generate high heat must be properly dissipated to avoid damage to electrical components due to overheating.

Existing computer mainframes dissipate heat by installing a cooling fan directly on the casing to form an air flow through the cooling fan to discharge the hot air in the casing and send cold air into the casing to dissipate heat. However, the cooling fan is directly fixed to the casing with screws, so that the cooling fan is in direct contact with the casing, and the cooling fan will vibrate when it is running, which will generate noise, and the high-frequency vibration will affect the installation on the casing. The hard disk drive in the casing causes the hard disk drive to be damaged when the read-write head collides with the magnetic track when the hard disk drive is performing an access action during high-speed operation. Therefore, in order to prevent the cooling fan in operation from affecting the hard disk drive, shock absorbing measures must be taken between the cooling fan and the casing to avoid damage to the hard disk drive.

As shown in Figure 1, Taiwan Patent Announcement No. M283493 "Shock Absorbing Structure for Cooling Fan" is installed in the electronic equipment with at least one cooling fan to provide heat dissipation for each component in the electronic equipment. In the cooling fan 11 The four corners are provided with combining holes 110, in which a shock-absorbing assembly 12 made of a shock-absorbing material is installed, and then the fixing components 13 such as bolts or rivets pass through the combining holes 110 and are fixed on the On the fixing frame 14 of the electronic device, the shock-absorbing component 12 is wrapped between the fixing component 13 and the coupling hole 110 to achieve a shock-absorbing effect.

The vibration energy generated by the cooling fan 11 is absorbed by the shock absorber assembly 12 to reduce the transmission of the vibration energy to the fixing frame 14, thereby reducing vibration noise and avoiding the impact of vibration on the hard disk drive.

But this radiating fan 11 directly contacts this fixing frame 14, there is not any shock-absorbing facility therebetween, so the shock-absorbing effect is not good, still needs to be improved.

Also as shown in Figure 2, the Chinese Taiwan Patent No. M269691 "radiating fan installation device with shock-absorbing structure" includes a fan frame 2 with a flange 21 and a plurality of buffer washers 22 arranged on the fan frame 2 , the flange 21 has a perforation 210, and the buffer washer 22 has a positioning portion 223 extending from a flange-shaped elastic buffer portion 221, so that the buffer washer 22 is assembled in the perforation 210 of the flange 21 of the fan frame 2, The positioning part 223 is hooked into the through hole 210 of the flange 21, and the elastic buffer part 221 has a through hole 225; After being installed on a supporting member (not shown in the drawings) such as a computer mainframe, the elastic buffer portion 221 of the buffer washer 22 is sandwiched between the flange 21 of the fan frame 2 and the supporting member, and can pass through the buffer washer. 22 Absorb shock energy.

Although there is a buffer washer 22 between the flange 21 of the fan frame 2 and the support, and the shock energy can be absorbed by the elastic buffer portion 221 of the buffer washer 22, the hole wall in the through hole 210 is still in contact with the fixing assembly. contact, and the fixing component is directly assembled on the support of the computer host, when the motor in the fan frame 2 is running, the vibration energy generated by it is transmitted to the fixing component through the hole wall of the through hole 210 and then transmitted to the computer The supporting member of the main engine; although the elastic buffer portion 221 of the buffer washer 22 is used to absorb shock energy between the fixed assembly and the flange 21 of the fan frame to reduce energy transmission, it is still fixed in the through hole 210 of the flange 21 The components are in contact and there is vibration energy transmission, so the effect of shock absorption cannot be fully achieved.

In addition, network-type servers have higher requirements for cooling conditions, because the computing speed of the server is much higher than that of a terminal stand-alone computer, and the higher the computing speed, the higher the heat energy will be. Only a single number of cooling fans It seems that the necessary heat dissipation effect cannot be achieved. In order to reduce heat and improve heat dissipation efficiency, the most direct way is to increase the number of cooling fans, so as to improve heat dissipation efficiency by increasing the speed and flow of airflow; but in the case of increasing the number of cooling fans, Relatively, the vibration energy generated by the heat dissipation fan increases, which has a huge impact on the hard disk drive running at high speed.

Therefore, to improve the existing cooling fan fixed in the casing, the vibration energy cannot be absorbed through the shock absorber assembly 12 or the buffer washer 22 to avoid the impact of vibration factors on the lack of damage to the hard disk drive, especially for servers that use a large number of heat sinks , The impact on the hard disk drive is relatively improved, and it has become a problem that the server is eager to solve.
