Snap fastener structure for heat sink

The utility model discloses a fastening structure of a radiator: the radiator is combined with a heating component on a motherboard socket; the radiator absorbs heat from the heating component. The fastening structure comprises a first fixing seat, a second fixing seat and a fastener, wherein, the first and the second fixing seats are arranged at two opposite ends of the socket; the fastener runs through a gap of a plurality of heat dissipating fins of the radiator and is arranged on the radiator in a spanned way; the two ends of the fastener are pivotally connected and selectively fastened with the first and the second fixing seats; the elastic part in the middle section of the fastener is used for forcing the radiator to be adhered to the heating component, thereby keeping the integrity of the heat dissipating fins of the radiator and bringing the highest heat dissipating efficiency.
