Abstract
A serial fan of the present invention includes a first fan and a second fan, each of which includes a housing and an impeller disposed in the housing. The housings respectively include a plurality of connecting elements, and there are several air-guiding recesses defined on the connecting elements of the first fan or the second fan, which can guide air to smoothly flow out from the housing so as to increase airflow and air pressure and reduce noise.
