Abstract: A fan module is provided, including a hub, a plurality of blades connected to the hub, and a plurality of longitudinal members. Each of the blades includes a base side connected to the hub, an end side opposite to the base side, a windward side, a leeward side opposite to the windward side, a windward surface, and a leeward surface opposite to the windward surface. The windward and leeward sides are connected to the base side and the end side. Each of the longitudinal members is disposed on the leeward surface of each of the blades, connected to the end side, and has a first end, a second end, and a tapered structure. The first and second ends face the leeward and windward sides respectively. The height of the first end is the maximum height of the longitudinal member. The tapered structure is connected to the second end.
