The dustproof bushing 31 in which the support jaw 31b is spaced apart from the support jaw 31b is inserted, and the support jaw 61a is provided at both ends at one end of the central through hole 11 of the plurality of upper and lower cooling fan fixing holes. The formed dustproof tube 61 is inserted, and the cooling fan fixing pin 45 is inserted into one end of the dustproof tube 61 through the dustproof bushing 31. .
이때, 방진튜브(61)는 그 길이가 냉각팬의 상하간격보다 길지만, 길이방향으로 압출시킬 수 있으므로 압축시켜 냉각팬의 고정구멍 사이에 끼울수 있고, 삽입 후에는 진동을 효과적으로 흡수할 수 있는 역할을 하게 된다.At this time, the dustproof tube 61 is longer than the upper and lower intervals of the cooling fan, but can be extruded in the longitudinal direction can be compressed and inserted between the fixing holes of the cooling fan, the role that can effectively absorb the vibration after insertion.

상기한 구성에서는, 냉각팬 고정나사없이도 간편하게 냉각팬을 조립하여 냉각팬이 약간의 틈새가 있는 상태로 고정되므로, 냉각팬에 의해 발생된 진동을 효과적으로 흡수할 수 있게 된다.In the above configuration, the cooling fan is easily assembled without the cooling fan fixing screw, and the cooling fan is fixed in a state where there is a slight gap, so that the vibration generated by the cooling fan can be effectively absorbed.
이상에서 상세히 설명한 바와 같이, 본 발명의 방진재가 부설된 냉각팬 및 냉각팬 고정체는, 냉각팬에서 발생한 진동이 냉각팬 고정구멍과 고정나사를 통해 고정체에 전달되는 단점을 지닌 종래기술과는 달리, 냉각팬 고정구멍에 방진부싱과 너트가 삽설된 방진재 또는 방진튜브를 부착하여 냉각팬에서 발생된 진동이 고정체을 통하여 시스템에 전달되는 것을 방지할 수 있고, 고정너트를 용이하게 고정체에 조립할 수 있으며, 냉각팬 고정나사 없이 조립할 수 있는 본 발명의 냉각팬 및 냉각팬 고정체는 방진에 효과적이면서 간편하게 냉각팬을 고정체에 고정할 수 있다.As described in detail above, the cooling fan and the cooling fan fixing body in which the vibration isolator of the present invention is installed are different from the related arts in which vibration generated in the cooling fan is transmitted to the fixing body through the cooling fan fixing hole and the fixing screw. Alternatively, by attaching a dustproof material or a dustproof tube in which a dustproof bushing and a nut are inserted into the cooling fan fixing hole, vibration generated from the cooling fan can be prevented from being transmitted to the system through the fixing body, and the fixing nut can be easily assembled to the fixing body. The cooling fan and the cooling fan fixing body of the present invention, which can be assembled without the cooling fan fixing screw, can effectively fix the cooling fan to the fixing body while being effective in dustproofing.
