ABSTRACT:
An electronic device with a heat-dissipation structure is disclosed. The electronic device comprises a housing, a printed circuit board assembly, and a heat sink. The printed circuit board assembly is disposed in an interior of the housing, and the printed circuit board assembly forms a high-temperatured heat flow area and a low-temperatured heat flow area in the electronic device. The heat sink is disposed between the printed circuit board assembly and the housing and in the low-temperatured heat flow area for balancing heat flow and homogenizing temperature of the electronic device to enhance heat-dissipation efficiency.
