Abstract
a serial fan device including two fans linked serially is provided. Each of the two fans has a housing, a driving member and a fan wheel, the housing has an outer frame and a base, the outer frame has two openings and a guiding channel linking the two openings, the driving member is disposed on the base, and the fan wheel is rotatably coupled with the driving member. At least one of the two fans has a positioning rim on the outer frame for the base to couple therewith, and a radial buffer gap is formed between an outer periphery of the base and an inner periphery of the positioning rim. Accordingly, the radial buffer gap can largely reduce the vibration transmitted from the base to the outer frame.
