We come into contact with heat-dissipating electric fans every day, and the two goals of the cooling function of the heat-dissipating fan are the air volume and breeze pressure of the cooling fan. And what is the relationship between the air volume of the radiating fan and the air pressure of the radiating fan?
The air volume of the heat-dissipating electric fan is the plane velocity product of the ventilation area. In an environment where the ventilation area is inevitable, the greater the plane velocity, the greater the air volume of the cooling fan. And the greater the air volume of the heat-dissipating electric fan, the greater the heat absorbed by the atmosphere, the more heat can be taken away by the transfer of the atmosphere, and the better the heat dissipation effect. When the plane speed is constant, the larger the outer diameter of the fan blade impeller, the larger the ventilation area, and the greater the air volume of the heat-dissipating fan.
Normally, in order to stop normal ventilation, it is necessary to restrain the resistance in the flow path of the heat dissipating fan, and the heat dissipating fan needs to generate a pressure of the heat dissipating fan that limits the air supply resistance, which is the wind pressure of the heat dissipating fan. In order to realize the intent of the cooling fan to supply air, static pressure and dynamic pressure are required. The total pressure is the algebraic sum between the static pressure and the dynamic pressure. The total pressure refers to the total pressure increase given by the heat-dissipating fan, that is, the total pressure difference between the outlet and the inlet of the heat-dissipating fan.
In practical applications, the nominal large air volume does not mean the actual fan heat supply air volume, and strong ventilation does not mean large air volume. When the atmosphere behaves, the airflow will meet the resistance of a fan of hot inserts or components in its behavior path, and its resistance will limit the atmosphere's liberation activities. Increase the atmosphere flow rate and reduce the atmosphere pressure;
