As long as it comes to cooling fans, people know that there are many types, different types have many models, and different models have different parameters. Choosing a truly suitable product fan requires sufficient understanding. Do you know what types of common cooling fans, and do you know its Features? Common cooling fan types are as follows: Axial Fan The blades of an axial fan promote air flow in the same direction as the shaft. The impeller and propeller of an axial flow fan are somewhat similar. In operation, most of the airflow is parallel to the axis, in other words, flows in the direction of the axis. When the inlet air flow of the axial flow fan is 0 static pressure free air, its power consumption is the lowest, and it increases with the increase of the back pressure of the air flow during operation. Axial fans are usually installed on the cabinet of electrical equipment and sometimes integrated on the motor. Due to the compact structure of the axial flow fan, it can save a lot of space, easy to install and widely used. Axial fan features: high flow, medium pressure centrifugal fan When the centrifugal fan is working, the blades push the air to flow perpendicular to the axis (ie radial), the air intake is along the axis, and the air outlet is perpendicular to the axis. In most cases, the cooling effect can be achieved by using an axial fan, but sometimes if a 90-degree airflow rotation or greater wind pressure is required, a centrifugal fan must be selected. Strictly speaking, the fan is also a centrifugal fan. Centrifugal fan features: limited flow. High pressure mixed flow fans are also known as diagonal flow fans. At first glance, a mixed-flow fan is no different from an axial-flow fan. In fact, the air inlet of the mixed flow fan is along the axis, but the air outlet is along the diagonal direction of the axis and the vertical axis. Since the blades and the shroud are called conical, the wind pressure of this fan is high. Under the same size and other comparable performance, the noise of the centrifugal fan is lower than that of the axial fan. Mixed-flow fan features: high flow and relatively high wind pressure cross-flow fans can generate large-area wind flow, which is usually used to cool large surfaces of equipment. The inlet and outlet of the fan are perpendicular to the axis. The cross-flow fan uses a longer barrel-shaped fan impeller to work. The barrel-shaped fan blades are relatively large in diameter. Due to the larger diameter, a relatively low speed can be used on the basis of ensuring the overall air circulation, thereby reducing the noise caused by high-speed operation. Cross-flow fans can produce large areas of large area wind flow, usually used to cool large surfaces of equipment. The inlet and outlet of the fan are perpendicular to the axis. The cross-flow fan uses a longer barrel-shaped fan impeller to work. The barrel-shaped fan blades are relatively large in diameter. Due to the larger diameter, a relatively low speed can be used on the basis of ensuring the overall air circulation, thereby reducing the noise caused by high-speed operation. Mixed flow fan features: low flow, low wind pressure. There are different types of axial fans, centrifugal fans and mixed flow fans in China. Among them, Jiangshan technology DC fan belongs to axial fan. In this type, you can choose different types of fans. Our cooling fans are widely used in communication equipment, LED stage lighting, medical equipment, aerospace and other industries.
