Thermal module

A thermal module, comprising:

• a first body and a second body, slidably connected to each other and forming an accommodating space together;
• a first fan assembly, disposed in the accommodating space, having a first hub and a plurality of first fan blades, the first hub connected to the first body;
• a second fan assembly, disposed in the accommodating space, having a second hub and a plurality of second fan blades, the second hub connected to the second body, the first hub and the second hub overlapping each other;
• and
• a shaft, pivotally disposed in the first body and the second body, engaged with the first fan assembly and the second fan assembly,
• wherein the shaft is adapted to pivot relative to the first body and the second body to drive the first fan assembly and the second fan assembly to synchronously rotate, and the first body and the second body are adapted to receive an external force to relatively slide and drive the first fan assembly and the second fan assembly to oppositely move along the shaft to be switched to a folded state or an unfolded state.
