Abstract
A heat sink includes a substrate, at least a first fin set and at least a second fin set. The first fin set is disposed on the substrate and has a plurality of first fins, and the first fin has a plurality of first holes. The second fin set is disposed on the substrate and has a plurality of second fins, and the second fin has a plurality of second holes. The total area of the second holes is larger than that of the first holes. An electronic device and a heat exchanger which are configured with the heat sink are also disclosed. The structure and configuration of the heat fins can increase the wind guiding effect, and thus improve the heat-dissipation efficiency.
