Abstract
A heat dissipation device for being in thermal contact with a heat source includes multiple heat dissipation fins, a heat pipe and a fan. Each of the heat dissipation fins includes a plate and an air guiding body. The plate has a thermal contact side used for being in thermal contact with the heat source. An acute angle is formed between an extension side of the air guiding body and the thermal contact side. The heat pipe penetrates through the plates. The fan used for forming an air current is installed at a side of the heat dissipation fin opposite to the thermal contact side. The air guiding body and the heat pipe are disposed in a flowing path of the air current. Thereby, the air current is guided toward the heat pipe and the amount of air flowing through the heat pipe is increased.
