The fans of LED mobile advertising vehicles may not be worth mentioning at all, but there is also an important link between fans and mobile advertising vehicles. The fan is an electronic component that can give heat to a mobile advertising vehicle and it is relatively easy to dissipate heat. In order to stabilize the speed of driving a mobile advertising vehicle, there will be some failures. The maintenance of LED mobile advertising fan fans is an urgent task. 1.

The fan needs to be cleaned regularly so that it can be used without affecting the use and it can be reduced to a certain extent. 3. If the fan of the LED mobile advertising vehicle is performing heat dissipation, the obtained effect is not very good. It may be caused by the fact that the center of gravity of the fan blade of the LED mobile advertising vehicle fan is not caused by the axis. This is also what the old drivers often say about eccentricity. Although this kind of failure seems to be not very serious at the moment, it will be a big danger after a long time. At this point you can remove it, use a thin line and drop it in the middle, wait for a while, see if it sinks in that direction, and then gently place on the grinding wheel where it will sink.
