Abstract
A heat dissipation device includes a heat dissipation fin module, a heat pipe and a centrifugal fan. The heat pipe is connected to the heat dissipation fin module at one end and connected to a heat generating source at an opposite end. The centrifugal fan includes a motor rotating a centrifugal impeller. A spiral housing encloses the centrifugal impeller and the motor. The spiral housing includes an air inlet, a first air outlet and a second air outlet. The air inlet exposes the centrifugal impeller such that the rotating centrifugal impeller introduces air through the air inlet. The first air outlet is connected to the heat dissipation fin module and the heat pipe, the second air outlet exposes the heat pipe. An isolation wall is disposed between the second air outlet and the air inlet.
