Abstract: A cooling module is presented, which includes a heat sink and a fan unit. The heat sink provides a base plate and a plurality of fins, with an outlet extending through the base plate and the fins formed on a first surface of the base plate, and with a second surface of the base plate attached to a heat generating unit. The fan unit is rotatably mounted on the heat sink and aligned with the outlet. With the above-mentioned structure, an air-guiding channel is formed between any adjacent two of the fins and communicates with the outlet for a part of air outputted by the fan unit to be guided through the air guiding channels and exhausted by the outlet. Consequently, disturbed flows and wind noise are decreased while cooling efficiency is improved.
