Abstract
A portable electronic device includes a main body and a heat dissipation module with a tiltedly installed centrifugal fan inside thereof. The main body includes an upper housing wall and a lower housing wall. The heat dissipation module includes a centrifugal fan, a heat dissipation fin array and a heat pipe. The centrifugal fan includes an impeller, a radial air outlet, an upper axial air inlet and a lower axial air inlet, wherein the centrifugal fan has a first side that is in contact with the upper housing wall and an opposite second side that is in contact with the lower housing wall. The heat dissipation fin array is located at the radial air outlet of the centrifugal fan. The heat pipe has a first end connected with the heat dissipation fin array and a second opposite end connected with a heat source.
