As an important component in a computer system, a cooling fan provides heat dissipation within the computer to ensure that components can operate at a stable temperature. The choice of material for the cooling fan is crucial to the cooling effect. In this paper, we will discuss the advantages and disadvantages of different materials of cooling fans, and accordingly talk about the relationship between volumetric efficiency and cooling fan materials.

Firstly, we need to understand the working principle of a cooling fan. A cooling fan generates airflow by rotating to remove heat from inside the computer. The choice of material for a cooling fan affects its cooling effectiveness because different materials have different thermal conductivity and thermal emissivity, which affects the cooling ability of the cooling fan.

Metal alloy cooling fans are a common material for cooling fans and are more effective at dissipating heat. Metal alloy cooling fans have a high thermal conductivity, which can quickly transfer heat to the heat sink, thus improving the cooling effect. In addition, metal alloy cooling fans also have a higher heat radiation rate, which can radiate heat into the surrounding environment, further improving the cooling effect.

Plastic cooling fans are also a common material for cooling fans, and their cooling effect is relatively poor. The thermal conductivity of plastic cooling fans is low, and it takes a long time for the heat to be transferred to the heat sink, thus affecting the cooling effect. In addition, the thermal radiation rate of the plastic cooling fan is also low, unable to radiate heat to the surrounding environment, further reducing the cooling effect.

Fibre reinforced material cooling fan is a new type of cooling fan material, which has a better heat dissipation effect. The thermal conductivity and thermal radiation rate of the fibre-reinforced cooling fan are both higher, which can rapidly transfer heat to the heat sink and radiate heat to the surrounding environment, thus improving the heat dissipation effect. In addition, the weight of the fibre reinforced material cooling fan is lighter, which can reduce the weight of the computer and improve the portability of the computer.

In summary, the choice of material for cooling fans is critical to the effect of heat dissipation. Metal alloy cooling fans, plastic cooling fans and fibre-reinforced cooling fans all have their own advantages and disadvantages. When choosing a cooling fan, you need to choose the right material according to the actual needs of the computer and the cooling environment. At the same time, the volumetric efficiency of the cooling fan is also an important consideration, you need to choose the right cooling fan according to the actual needs of the computer.
