Abstract
A fan module including a first body, a second body, a first fan assembly, a power module, and a second fan assembly is provided. The second body is slidably disposed at the first body to form a circulation space together. The first fan assembly is rotatably disposed at the first body and has sliding grooves. The power module is disposed in the first body and connected to the first fan assembly. The second fan assembly is rotatably disposed at the second body and has sliding portions, respectively and slidably disposed in corresponding sliding grooves. The power module is adapted to drive the first and second fan assemblies to rotate relative to the first body. A link module is adapted to drive the first and second bodies to relatively slide along an axial direction, so that the first and second fan assemblies are relatively separated or overlapped along the axial direction.
