Then the last part continues to discuss the important influence of blade material on the performance of the cooling fan.

(1) Blade material

Plastic blade:They are lightweight, low in manufacturing cost and can be quickly produced by injection molding. However, plastic blades generally produce more noise than other materials and may have lower strength and durability.

Fibrous composite material:It has good strength and durability, can provide lower noise and higher airflow efficiency, can improve the efficiency and output power of the fan.

Aluminium alloy:It is a commonly used blade material, with high strength, light weight and easy processing characteristics. Aluminum alloy has good thermal conductivity, can effectively dissipate heat, and improve the heat dissipation effect of the fan. The blades of our AC-F60300 air radiator cross flow fan are made of high-quality aluminum alloy metal material, which is not easy to deform, well-made, strong and durable frame, and long service life. In addition, the working temperature of the air radiator cross-flow fan is -10℃ ~ 70℃ ultra-high temperature range, aluminum structure, waterproof function is strong, suitable for most outdoor environments, this waterproof moisture-proof AC cross-flow cooling fan is especially suitable for outdoor advertising display heat dissipation.

The importance of air density for cooling fans

The air density is the key factor affecting the cooling performance of the cooling fan. Under different environmental conditions (such as temperature, altitude and climate), the air density will change, which will affect the heat dissipation effect. As a professional cooling fan manufacturer, our products cover 110V AC cooling fan and 220V AC cooling fan. We are both a professional 110 v ac cooling fan factory and a reliable 220 v ac cooling fan factory , committed to providing high-quality cooling solutions in various air density environments.

Influence of air density on cooling effect of cooling fan

High-density air (cold air) environment: In an environment with higher air density, such as a low temperature environment, the air contains more molecules per unit volume, making the air able to carry more heat, so the heat dissipation effect is better.

Low-density air (hot air) environments: At higher temperatures or at high altitudes, the air is less dense, reducing its heat transfer capacity. In this environment, the efficiency of the cooling fan will be reduced, especially for 220V AC cooling fans, and the performance in low-density air is an important design consideration.
