Centrifugal fans and cross-flow fans are more common types, but their characteristics are different. Let's take a look at the difference between centrifugal fan and cross-flow fan.
First, the construction
Firstly, the centrifugal fan is constructed by the casing, the impeller, the main shaft and the motor, and the cross-flow fan is different. The cross-flow fan is mostly a long cylindrical blade, and the centrifugal fan is a sheet.
Second, the principle
Centrifugal fans are the principle of converting kinetic energy into potential energy. The high-speed rotating impeller accelerates the gas and converts kinetic energy into potential energy. Depending on the mechanical energy of the input, it is a driven fluid machine.
The flow of the cross-flow fan runs through the impeller and is affected by the two forces of the blade. Therefore, the airflow can reach a long distance without turbulence. Since the airflow is forcibly folded in the impeller, the head loss is large and the efficiency is relatively high. low.
