A heat dissipation device includes a heat sink and a cooling fan arranged thereon. The cooling fan includes a motor-stator and an impeller mounted around the motor-stator. The motor-stator is arranged on a middle of the heat sink. The heat sink includes a base and a plurality of fins extending upwardly from the base. The heat sink defines a plurality of notches incising the fins. The notches are angled towards the middle of the heat sink immediately under the motor-stator of the cooling fan.

Heat dissipation device

A heat dissipation apparatus includes a heat sink () and a fan () mounted on the heat sink. The heat sink includes a plurality of radial fins (). An air channel () is defined between every two adjacent fins. Each of the fins includes a main body () and an airflow guiding flange () extending upwardly and outwardly from a top side of the main body. The airflow guiding flange is twisted in a radial direction, such that an included angle between the airflow guiding flange and the main body is gradually increased from an outer side () towards an inner side () of the main body. The fan is used to generate airflow towards the heat sink. The airflow is guided into the air channels between the fins via the airflow guiding flanges.

Heat dissipation apparatus

An LED lamp () includes a lamp base (), an optical lens system (), an LED () mounted in the optical lens system and a heat dissipation device () interconnecting the lamp base and the optical lens system. The heat dissipation device includes a heat sink () and a heat pipe (). The heat sink includes a central block (), a plurality of fins () mounted on an outer circumferential face of the central block and a receiving hole () defined axially through the central block. The heat pipe is circumferentially retained in the receiving hole and in thermal contact with the LED.
