Miniature radiator cooling fan can adjust speed?

Hot sunny days in this June, it was like the steamed stuffed bun, our car the host needs to be moved out to blow air conditioning, so a cooling fan is very important, can adjust the micro cooling fan speed? And a cooling fan manufacturer tong chi below small make up let's look at the


1, the common micro cooling fans, if not treated with special design, the fan is not according to the environment temperature to adjust temperature, because of the micro cooling fan motor is fixed, as long as the voltage constant, fan power, the speed of the fan is much.


2, micro cooling fan voltage change, if you can change the fan power, which may also affect the speed of the cooling fan. Voltage can't change, but the cooling fan can adjust down, because if the voltage is too high, can cause the cooling fan too much electricity, drive IC current is too large, the temperature rise leads to a cooling fan is burn out.


3, inside the miniature cooling fan motor series a temperature resistance, higher or lower when the temperature changes, temperature resistance will also change accordingly, let series mini fan motor resistance change with it, so that the micro cooling fan speed changing.


4, using the PWM function of micro cooling fans, when environment temperature change, PWM set motherboard will be affected by the temperature of the earth through the send a message to the fan, changing the PWM duty cycle, mini fan will be compared with the size of the rotational speed of a linear change.
