used as a wind turbine. Because the only usable part is the fan.
The computer radiator fan
is a sort of
generator
. Because we all know that the
coil
part of the computer radiator fan consists of
the stator

Ring-shaped
The permanent magnet
serves as the
rotor
, and it This is what generators do
Build
. Personally, I don't recommend using a computer heatsink fan as a wind turbine, because even the largest computer heatsink fans have limitations. We know that the number of
turns of the coil
determines the
voltage
("the speed of rotation and the fluxmagnetic are constant"), that is to say
p>
Cutting of the magnetic flux lines
The number of wires
. We also know that in simple terms, the thickness of the coil determines the size of the current Computer radiator fan coils are relatively thin, which means that we cannot get a relatively large current. the voltage, it will not be too high
(At a wind speed of 8 meters per second
) It is estimated that the voltage generated by. the fan on a general computer radiator is about 6 to 30 volts, and the maximum current is probably only 100 to about 800 mA
If you want to do this, you need to. always remove the frequency conversion circuit
circular
under the computer radiator fan
1·Then the coil heads with the. same winding direction of each turn of the coil can be connected in parallele, so that a larger current can be obtained, but the voltage is relatively low and the two wires drawn are
Alternating current
If you want direct current, you You can add a rectifier stack (diode group) later.
2. Each turn of the coil can be connected in series (pay attention to the connection sequence, just like when multiple batteries are connected in series, pay attention to the positive pole connections and negatives), that is, the start of one coil is connected to the end of the previous coil, and they are connected in sequence, leaving the end of the first turn of the coil and the start of the last turn of the coil as conductive wires.
Such a connection can obtain a relatively high voltage but a low current. It's alternating current. If you want direct current, you can add a rectifier stack (diode group) later.
3. Take each turn out of the spool. This is the acquisition
of three-phase electricity
., this type of connection is very flexible, and the voltage and current can be adjusted within the range after its output, that is to say according to 1· and 2· above. The biggest advantage is flexibility.
