Abstract
A heat-dissipating fan includes a housing having a peripheral wall defining a compartment receiving a shaft seat. The peripheral wall includes a wire-guiding slot in communication with the compartment. A base is coupled to the housing and includes a coil unit and a connection port electrically connected to the coil unit. The connection port faces the wire-guiding slot. A power line includes a first end connected to the connection port and a second end extending through the wire-guiding slot. An impeller includes a hub, a shaft mounted to the hub and coupled to the shaft seat, and a permanent magnet mounted to the hub. The permanent magnet faces the coil unit. The connection port is located on a reference line passing through the shaft seat and the wire-guiding slot. A distance between the connection port and the wire-guiding slot is shortened to enhance assembling convenience of the power line.
