Description

Fan Shock Assemblies

technical field

The invention relates to a shock absorbing structure, in particular to a fan shock absorbing assembly applied to an electronic device.

Background technique

Most of the computer casings are equipped with a plurality of cooling fans to generate air convection through the operation of the cooling fans, and to dissipate heat for the electronic components inside the casing. The cooling fan must be fixed on the casing, and the traditional fixing method mostly uses screws to directly lock the fan inside the casing or the fan frame inside the casing, but the method of locking the fan with screws is time-consuming and expensive. strenuous. Therefore, some people have proposed a related design of using the fan frame to quickly disassemble and install the fan. This fan frame can be fitted and fixed by multiple fans at one time, and then be inserted into the casing together with the fan and the fan frame to fix the fan in the casing. in the chassis. Using the fixing method of the fan frame, multiple fans can be disassembled from the casing at one time without using screws, which improves the efficiency of installation.

However, because the running fan will generate vibration, no matter the fan is directly screwed or indirectly fixed to the casing by the frame, the vibration generated by the fan will be transmitted to the casing directly or through the frame, which will affect the storage device of the computer host. For example, the operation of hard drives and optical drives. This situation most often occurs on large-scale server hosts or industrial computer hosts equipped with many cooling fans, because the cooling fans inside these two computer hosts are not only large in number but also have a high speed, such as the 1U cooling fan commonly used in the industry . Although there are some vibration isolation solutions in the industry, such as placing a rubber pad between the fan fixing hole and the frame, using the rubber pad as a medium for contact between the frame and the fan, and then using the rubber pad to absorb the vibration generated by the fan. However, because each fan has quite a lot of fixing holes, and a frame needs to be assembled with multiple fans, the process of assembling the fan and rubber pads to the frame is quite labor-intensive (usually a fan needs to assemble 4 to 8 rubber pads). Although the way of installing rubber pads on the fan body can absorb the vibration of the fan, it makes the procedure of disassembling and replacing the fan more complicated, and cannot meet the requirement of improving economic efficiency.
