  • Patent number: 7688590
    Abstract: A thermal module suitable for cooling a heat generating element within a casing of an electronic apparatus includes a fan, a heat sink and a heat pipe. The fan is mounted within the casing for generating airflow to an opening of the casing. The heat sink is mounted within the casing between the opening of the casing and the fan, such that the airflow generated by the fan passes through the heat sink and then flows out of the opening. The heat pipe contacts the heat generating element, extends from the heat generating element to the heat sink, and extends along a periphery of the fan to contact the heat generating element again.
