Auto cooling fan using temperature control technology, let you fondle admiringly.

the principle of temperature control cooling fan is: on the basis of fans around the rise of heat to improve the fan speed, at the same time increase the flow of air ( Exhaust air) 。 Temperature control fan using a thermistor temperature sensor, mounted on the fan hub sensors to detect the temperature of the fan. In this configuration will xu properly installed fan, when the fan installation is complete, thermistor can be induced by special connection wire.

fan operation is changed by the condition of the heat, operating at a slower speed, fan will produce less noise, and consume less energy. In most of the design requirements, the fan speed running hours after the design of the air temperature is usually bigger than zui temperature value is lower. Usually, low speed of cooling fan can work enough to finish it. But also should consider when choosing and installation: first, the selected fan must be able to provide enough air output ( Speed) High temperature circumstances, the cooling of hot air inside the equipment; When the temperature is lower and the heat flow is less time to do instead of work. Secondly, on the sensor installation position should be paid attention to when the choice, the sensor in place, can make the sensor directly clamped on the surface of need cooling. In operation, a temperature control fan, if feel thermistor temperature is higher when operating at a rapid speed; And the temperature is lower, will be operating at low speed; In the middle of the high and low, the fan speed will almost will not change by temperature. Fan of the temperature change is slow, the fan speed change is slower, not suddenly change fan speed and noise. The length of the reaction time mainly depends on its sensor for thermal sensitivity.
