Industrial motherboard cooling fan is mainly bracket type, no frame protection, fan blade counter clockwise rotation design, vertical type, the wind yearns to blow around, but also blow down. An important problem to be noted is that the single fan should not fall to the ground
As can be seen from the above figure, the leaves are thin and long, and the contact area between the leaves and the wheel drum is very small. It is easy to break the fan when the leaves fall to the ground. If one of the fan blades is broken, the whole cooling fan will lose its balance and cause damage
Therefore, the cooling fan manufacturers are aiming at the samples. Because there is no standard outer box for the samples, they usually wrap them in bubble bags. It is recommended that the samples be taken out on the desktop, so that the chances of falling to the ground are much less.
