Why do LED displays need to install a cooling fan?
2025-09-22
High temperatures can rapidly increase the probability of electronic component failure, leading to a decrease in the reliability of LED displays. High temperature has a significant impact on the reliability of LED displays, so heat dissipation design is necessary.
The difference between DC cooling fan and AC fan
2025-09-22
Cooling fans can be divided into two types based on voltage: AC fans and DC fans. Apart from the difference in voltage, what are the differences in their internal structures?
Firstly, the internal structure of the AC fan consists of two coil windings (starting winding and running winding) connected in series, creating three crossing points. The series connection point is the common terminal. The ……
How to determine the minimum starting voltage for a cooling fan?
2025-09-22
Many people may think that the starting voltage of a cooling fan is the voltage written on the label, but in fact, the smaller starting voltage is much smaller than the rated voltage. Let me introduce these two voltages to you: starting voltage refers to the small voltage that can start the cooling fan when it is suddenly powered on. The working voltage refers to the voltage at which the cooling f……
