Abstract

The present disclosure relates to a centrifugal fan and a method for manufacturing the same. The centrifugal fan can easily implement a three-dimensional blade by including a main plate, a blade, and a shroud that injection-molded as one body, thereby reducing the weight of the centrifugal fan and improving the operating efficiency. In addition, since assembly processes such as fastening or welding are unnecessary when manufacturing the blade, the defect rate of the blade can be reduced and the fluidity performance can be prevented from deteriorating due to traces of welded areas.
