Vibration and noise levels are one of the most important characteristics of the coolers quality, which are widely used for cooling in modern electronic equipment (personal computers, medical equipment, etc.).
By order of one of the medical equipment manufacturers, we carried out balancing coolers batch in the amount of 100 pieces.
For this purpose, a special stand was manufactured, which was a light platform suspended on rigid steel strings.
An epoxy quick-hardening compound was used as a corrective weight, applied to the coolers blades to compensate for the imbalance. It should be noted that the corrective loads weights were not higher than several hundredths of a gram.
As a result of balancing, coolers residual vibration decreased on average by more than 10 times and ranged from 0.01 to 0.05 mm/s for the entire batch of products.
