The Benefits of Using Temperature-controlled Fans in Mobile Radios

The vehicle-mounted radio refers to a radio walkie-talkie that can be installed on vehicles, ships, airplanes, and other vehicles, is directly powered by an external power source, and uses an external antenna.

The thermal effect of the current will convert the electrical energy into heat when the current passes through the conductor. Due to the internal resistance of the power supply and electrical components of the vehicle-mounted station, the vehicle-mounted station will emit heat after being used for a period of time. In order to dissipate the heat inside the vehicle-mounted station in time, Generally, a cooling fan is used to speed up the airflow in the vehicle station to speed up the heat dissipation of the equipment in the vehicle station.

But sometimes the ambient temperature is relatively low, the car station is in the standby state, and the heat generated by the device is slower than the speed of heat exchange with the surrounding air. At this time, the cooling fan continues to work with the original power, which is undoubtedly a waste of energy.

So now many vehicle-mounted stations are equipped with temperature-controlled fans, and the air pressure and air volume of the fans are controlled by the temperature changes in the vehicle-mounted stations to achieve the effect of energy-saving.
