A cooling fan is a type of fan used to carry away the heat generated by a device or system, and is widely used in a variety of devices such as computers, servers, and automobiles. They absorb and discharge heat by moving it quickly through the air, thus keeping the equipment within the normal temperature range. The following is an introduction to the specifications and performance of cooling fans.
1. Specifications
The specifications of a cooling fan usually consist of parameters such as size, rated voltage, fan speed, airflow, noise, bearings, service life, and fan connectors.
Size: The size of cooling fan is measured in mm, and the common ones are 8mm, 12mm, 14mm, 18mm and so on.
Rated voltage: 12V is common in the market.
Fan speed: in rpm, an important indicator of the fan's ability is the airflow in CFM.
Airflow: in CFM, an important indicator of fan capability.
Noise: in dBA, an indicator of fan noise.
Bearing: It is the soul part of the cooling fan, common ones are ball bearing, oil bearing, magnetic levitation bearing and so on.
Service life: is the time the fan can run normally.
Fan connector: is an easily overlooked detail part, the working voltage range is related to the DIY homemade cooling fan governor.
2. Performance
The performance of a cooling fan is mainly determined by the following aspects:
Airflow: Airflow is one of the main performance indicators of the cooling fan, which determines how much heat the cooling fan can take away. Generally speaking, the larger the airflow, the better the cooling effect.
Noise: the noise of the cooling fan is also an important performance indicator. Generally speaking, the lower the noise, the better the cooling fan experience.
Lifespan: The lifespan of a cooling fan is the amount of time that the fan can operate normally. Generally speaking, the longer the lifespan of the cooling fan, the lower the cost of use.
The performance of cooling fans is also affected by other factors, such as air cleanliness, temperature and humidity, current stability and human collision.
In conclusion, the specifications and performance of cooling fans are important factors to consider when choosing a cooling fan. When choosing a cooling fan, you need to select the appropriate specifications and performance according to the specific needs of the equipment and the use of the environment. At the same time, the correct use of cooling fans, including doing maintenance and choosing the right specifications and sizes, can extend the life.
