Server switching fan is one of the essential components in the server equipment, it works mainly by absorbing and distributing the heat in the air to achieve the purpose of server cooling. There are many types of server switching fans, generally divided into rotating fans, radiator fans and air-cooled coil fans. The following is a detailed introduction to the working principle, application scenarios and selection criteria of server switching fans.

1. Working Principle

The working principle of server switching fan is mainly to absorb and emit heat from the air to achieve the purpose of server cooling. When the server switching fan is activated, the fan will suck in air, then accelerate the air through the blades inside the fan and blow it towards the server's heat sink. The heat sink absorbs the heat from the air and radiates it into the air through the fins on the surface of the heat sink. After the heat in the air is absorbed by the radiator, the fan will draw the air in again and repeat the above process, thus realising the heat dissipation of the server.

2. Application Scenarios

Server switching fans are mainly used in data centres, server rooms and other environments that require high performance and high reliability. In these environments, servers need to run for a long time, and need to maintain a stable temperature and humidity to ensure the normal operation of the server. The server switching fan can effectively absorb and emit heat from the air, thus ensuring stable server temperature and prolonging the service life of the server.

3. Selection criteria

When choosing a server switching fan, you need to consider the following aspects:

(1) Airflow: The airflow of the server switching fan is one of the important factors for selection. The larger the airflow, the better the cooling effect. Generally speaking, the airflow of the server switching fan should be selected according to the power consumption of the server and the size of the heat sink.

(2) Noise: The noise of the server switching fan is also one of the important factors in the selection. The lower the noise, the lower the impact on the environment. Generally speaking, the noise of the server switching fan should be below 50 decibels.

(3) Life expectancy: The life expectancy of the server switching fan is also an important factor in the selection. The longer the lifespan, the lower the maintenance cost. Generally speaking, the lifespan of the server switching fan should be more than 5 years.

(4) Voltage: The voltage of the server switching fan is also an important factor in the selection. The higher the voltage, the faster the speed of the fan and the better the cooling effect. Generally speaking, the voltage of the server switching fan should be above 12V.

(5) Size: the size of the server switching fan is also an important factor in the selection. The larger the size, the better the cooling effect. Generally speaking, the size of the server switching fan should be selected according to the size of the server and the size of the heat sink.

To sum up, server switching fan is one of the essential components in server equipment, and it works mainly by absorbing and distributing heat from the air to achieve the purpose of server cooling. When choosing a server switching fan, you need to consider factors such as airflow, noise, life span, voltage and size to ensure the normal operation of the server and the cooling effect.
