What conditions must a cooling fan need to meet the dual 85 standard?

Cooling fan is usually found in computers, water dispensers, refrigerators, air conditioners, air purifiers, cars, and other internal devices. It is currently a popular cooling device in many industries.Axial flow fans are a type of heat dissipation fan, where the impeller of the axial flow fan drives the air to flow in the same direction as the shaft. The impeller of an axial flow fan is similar to a propeller. When it works, most of the gas flow is parallel to the shaft, which is simply along the shaft. When the inlet gas flows into free air with zero static pressure, the power consumption of the axial flow fan is low.

1. High temperature standard: The cooling fan needs to be able to work normally in a high temperature environment, usually requiring it to be able to operate for a long time in a high temperature environment of 85°C without damage.Cooling fans are usually made of high temperature resistant materials, such as high temperature plastic or metal materials, to ensure that they can maintain structural stability and electrical performance in high temperature environments.

2. High humidity standard: The cooling fan also needs to be able to work normally in a high humidity environment, usually requiring it to be able to operate for a long time at a relative humidity of 85% without being damaged.Cooling fans usually adopt moisture-proof and anti-corrosion designs, such as sealed structures and moisture-proof coatings, to ensure that their internal circuits and components are not affected by humidity.

During operation, power consumption will increase with the increase of gas flow back pressure. Axial fans are usually installed in electrical equipment cabinets and sometimes integrated with motors. Due to their compact structure, they can save a lot of space and are easy to install, making them widely used.
