Abstract
A heat sink includes two heat spreaders spaced from each other and a plurality of heat dissipation fins disposed between the heat spreaders. The heat dissipation fin is curved from one of the heat spreaders to the other one of the heat spreaders. A curved air passage is formed between every two adjacent heat dissipation fins. The heat dissipation fin can resiliently deform to change a distance between the heat spreaders. The present disclosure also discloses an electronic device incorporating such a heat sink. The electronic device comprises a shell and an electronic component mounted in the shell. One of the heat spreaders is attached to the electronic component and the other one is attached to the shell.
