Abstract

A fan module includes a first fan frame and a second fan frame. A side surface of the first fan frame includes a number of latching posts and a number of positioning portions extending toward the second fan frame. A side surface of the second fan frame defines a number of latching grooves in one-to-one correspondence with the latching posts. The side surface of the second fan frame further defines a number of rotating grooves in one-to-one correspondence with the positioning portions. Engagement between the latching posts and the latching grooves restricts a tangential relative displacement between the first fan frame and the second fan frame. Engagement between the rotating grooves and the positioning portions restricts an axial displacement between the first fan frame and the second fan frame.
