Electronic device and heat sink thereof
An electronic device includes a casing, a thermal generating element, and a heat sink. The thermal generating element is disposed within the casing and operates to produce thermal energy. The heat sink includes a thermal transfer plate and a plurality of movable thermal transfer members. The thermal transfer plate contacts the thermal generating element and includes a plurality of recesses. Each of the movable thermal transfer members has a weight end and a free end. The weight end is accommodated in the recess. The thermal energy produced by the thermal generating element is conducted to the movable thermal transfer members via the thermal transfer plate. When the casing is tilted by a certain angle, the movable thermal transfer member swings relative to the thermal transfer plate, such that the free end thereof points to a direction opposite to that of an acceleration of gravity under a normal state.
