Cooling fan experts know that as long as we disassemble the motor of the DC cooling fan, we can see that the DC cooling fan uses a variable frequency motor, which can be identified from the location of the coil. The frequency conversion motor control circuit board and the control chip will integrate the DSP function and the driving device, which simplifies the circuit structure. By programming the control chip, the motor speed can be changed.
Why is the micro fan installed on the computer, the computer will not drop? Many people have experienced that it is easy to drop the computer when the computer is used for a little longer, and the "cat" indicator ADSL (the link light is flashing) The ACT light is off), LAN (the link light is red, the ACT light is off), the indicator light of my wireless router is flashing normally, my laptop is connected to the Internet wirelessly, if the laptop is disconnected The desktop computer also dropped together, and the drop time ranged from 10 minutes to 1 hour.
Computer experts pointed out that this kind of problem will occur, and there may be a problem with the uplink circuit; where is the problem? To find it step by step, I have been engaged in network transmission for nearly 30 years. "Cat" ADSL; because the cat is very small, it is not valued by the main user, this phenomenon mostly occurs in the summer of high temperature, the main problem is: (ADSL) long-term operation is hot and does not work, it is enough to solve the problem of heat dissipation. Now computer experts teach you how to cool the computer without dropping the line. As long as we install a miniature fan on our computer, then the Internet will be smooth and no longer disconnected.
Micro fans - What are the applications of cooling fans? The following editor will take you to understand: Micro fans are widely used in various high-precision, high-density electronic products, handheld computers, micro cameras, micro projectors, and negative ion generation. devices, small high-speed cameras, car coffee machines, LED lighting, cooling modules, and other fields. If necessary, welcome to inquire and purchase, Chengda cooling fans welcome your calls.
