Cooling air volume of the cooling fan and radiator cooling fan, what is the relationship between air pressure?

In daily life we come into contact with the radiator cooling fan, and measure the radiator cooling fan cooling capacity is two important indexes of heat dissipation of the cooling fan air volume and air pressure. So heat radiator fan air volume and heat radiator fan? What's the relationship between air pressure, the following interpretation by YiRongChuan technicians for you: radiator cooling fan air volume refers to the cooling fan ventilation area of deposition rate of planar. When a certain ventilation area, the plane speed, the greater the heat radiator fan air volume is larger. And radiator cooling fan air volume, the greater the heat air is, the greater the air flow when the transfer can take weeks to take more heat and cooling effect is better. The plane speed is constant, the fan under the wheel diameter, the greater the ventilation area, the greater the radiator cooling fan air volume is larger. General to carry out normal ventilation, need to overcome the resistance of the heat radiator fan ventilation trip within, radiator cooling fan must overcome air resistance heat dissipation of the cooling fan pressure, the pressure is the wind radiator cooling fan. To achieve the purpose of the radiator cooling fan air supply, need to have static pressure and dynamic pressure. Total pressure to the algebraic sum of static pressure and dynamic pressure, total pressure is given by the radiator cooling fan in total pressure increase, the heat dissipation of the cooling fan total pressure difference between exports and imports. In real life applications, nominal maximum wind quantity is not the actual hot piece of delivery, and ventilation ability doesn't mean airflow. When air flow, air flow in the flow path will meet fan heat collection or element block, the impedance will limit the free flow of air. Increase the air volume, air pressure will decrease. Share to this today, radiator cooling fan air volume and heat radiator fan wind pressure is restricted each other, the relationship between not two isolated performance indicators. The relationship between them is - — Air volume decreases with the increase of the pressure difference and the heat dissipation of the cooling fan blade shape and the overall structure design decides the degree of restriction of them.
