Tips: Speed ​​and temperature control of DC cooling fan
The operation of DC cooling fan changes with the heat condition. If it runs at a slower speed, the fan will generate less noise and consume less energy. In most design requirements, the air temperature is usually lower than the maximum design temperature after the cooling fan has been running for several hours. Under normal circumstances, a low-speed cooling fan is sufficient to complete its work. However, it should also be considered when selecting and installing: First, the selected fan must be able to provide sufficient exhaust air volume (speed) to cool the hot air inside the equipment under high temperature conditions; When I was young, I did the opposite. Secondly, when selecting the installation position of the sensor, care should be taken to place the sensor in an appropriate position so that the sensor can be directly clamped on the surface to be cooled. In operation, a temperature-controlled fan will run at a faster speed if the thermistor feels that the temperature is higher, and at a lower temperature, it will run at a lower speed; In the middle, the fan speed will hardly change due to temperature. When the temperature of the fan changes slowly, the speed of the fan changes slowly, and the speed and noise of the fan will not change suddenly. The length of the response time depends mainly on the sensitivity of its sensor to thermal induction.
