Series fan
A series fan includes a first fan and a second fan. The first fan has a first frame, a second frame and a first flow passage. The second fan has a third frame, a fourth frame and a second flow passage. A first static blade is disposed at the first frame, while a second static blade is disposed at the fourth frame. A first dynamic blade assembly is disposed in the first flow passage, while a second dynamic blade assembly is disposed in the second flow passage. The second frame is assembled with the third frame. The first and second static blades serve to enhance the support strength and protection effect for the series fan. In addition, the first and second dynamic blade assemblies can be designed with an increased aerodynamic volume.
