Embodiment 1

[0035] like Figure 1-3 As shown, this embodiment provides a vibration performance testing device for a chassis fan module. A ventilation hole 8 is arranged on the upper cover of the chassis 1, and a rotating windshield 2 is arranged at the ventilation hole 8. The rotating windshield 2 can rotate downward and When dismantled, rotate the wind deflector 2 and fix it with the upper cover of the chassis 1 when it is in a horizontal state, and cover the ventilation holes 8. After rotating downward, the bottom end can be in sealing contact with the bottom wall of the chassis 1.

[0036] During the test, first make the rotating wind deflector 2 in a horizontal state, cover the ventilation holes 8, and conduct a hard disk vibration test. At this time, the hard disk 7 is affected by the mechanical vibration of the fan and the vibration of the wind flow, and the attenuation value of the hard disk is the mechanical vibration factor plus the wind flow. vibration factor. Then adjust the r...

Abstract

The invention discloses a device and method for testing the vibration performance of a chassis fan module. The upper cover of the chassis is provided with ventilation holes, and the ventilation holes are provided with a detachable rotating windshield. Make the rotating wind deflector in a horizontal state and fix it on the upper cover of the chassis, cover the ventilation holes to conduct a fan vibration test, and obtain the first hard disk attenuation value affected by mechanical vibration factors and wind flow vibration factors; The bottom end is in sealing contact with the bottom wall of the chassis, so that the ventilation holes are opened, and the fan vibration test is carried out to obtain the attenuation value of the second hard disk affected by the mechanical vibration factor; the attenuation value of the first hard disk is subtracted from the attenuation value of the second hard disk to obtain the wind flow vibration factor The affected third hard disk attenuation value; the ratio of mechanical vibration factor and wind flow vibration factor is obtained through the second hard disk attenuation value and the third hard disk attenuation value. The invention realizes the analysis of the mechanical vibration performance and the wind flow vibration performance, is easy to operate and flexible to use, and provides important assistance for the optimization design of the vibration reduction of the lifting fan.

Description

technical field [0001] The invention relates to the field of vibration testing of fan modules, in particular to a device and method for testing vibration performance of a chassis fan module. Background technique [0002] With the rapid development of electronic components, there are more and more electronic components with high density and high power consumption, and the heat generation inside the server also increases significantly. At this time, a high-speed fan is required to dissipate heat. The higher the fan speed, the faster the air flow velocity, the greater the mechanical vibration caused by the fan and the air flow vibration caused by the flow field, and the greater the impact on the hard disk, and the more obvious the fan vibration. Therefore, when the fan module is introduced, it is necessary to conduct vibration performance testing and tuning to judge whether the vibration performance of the fan module is good or bad, so as to optimize and tune the fan module wit...
