I believe that most people have come into contact with cooling fans, and they all know more or less about the purchase knowledge, but the more detailed professional knowledge is generally not understood by everyone. Today, the editor brings you 'dry goods'. Let us know the type of cooling fan. 1. The type of cooling fan is divided into three categories according to the direction of the fluid: 1. Axial fan blade: the fluid enters the fan blade along the central axis of the fan blade, and flows out along the central axis of the fan blade. 2. Centrifugal fan blade: The fluid enters the fan blade along the central axis of the fan blade and flows out along the radial direction of the fan blade. 3. Diagonal flow fan blade: fluid enters the fan blade along the central axis of the fan blade, and flows out along the fan blade axis and the fan blade radial direction. Second, the type of cooling fan is divided into three categories according to the distinction of airfoil: 1. Front curved type (forward-swept wing): The fan blade airfoil is curved forward along the running direction of the cooling fan, and is used in blowers. It is called multi-wing fan. 2. Backward curved (swept wing): The fan blade wing is curved backwards along the running direction of the cooling fan, which is used in blowers, also known as wheel-type fans. 3. Radial type (radiation wing): The fan blade wing shape extends outwards along the center of the cooling fan. This 'dry goods' is not good enough. Have you learned?
