Operation Control Conditions of Power Supply Cooling Fan

Article Source：Kinri Energy | Author：Kinri Energy | Issuing Time：2024.03.27
The cooling fan in the power supply is designed to help dissipate the heat generated inside the power supply and maintain its normal operating temperature. Therefore, controlling the operation of the cooling fan is very important. Next, let's explore the control conditions for the operation of the cooling fan.



The working temperature of the supplier

Firstly, we need to understand the operating temperature of the power supply. When the temperature of the power supply is too high, it can affect its normal operation and even lead to equipment failure. Therefore, the primary condition for controlling the operation of the fan is to monitor the temperature of the power supply. Once the temperature exceeds the preset safety range, the fan should start running to reduce the temperature.

Power supply load

Secondly, the load of the power supply is also an important control condition. When the load of the power supply increases, the heat generated will also increase accordingly. To ensure that the power supply can maintain a suitable temperature under various load conditions, we need to adjust the operation of the fan according to changes in load. When the load increases, the speed of the fan should increase accordingly to maintain a suitable working temperature.

Ambient temperature

In addition, environmental temperature is also a control condition that cannot be ignored. If the ambient temperature is too high, even if the temperature of the power supply is within a safe range, the operation of the fan should be strengthened to prevent adverse effects of external hot air on the power supply.

In summary, for power supplies with cooling fans, the control conditions for fan operation mainly include the working temperature, load, and ambient temperature of the power supply. By properly controlling these conditions, we can ensure that the cooling fan starts operating at the appropriate time, thereby maintaining the normal working state of the power supply.
