A heat sink with a built-in fan includes a heat radiation base, a heat radiation fin module and a fan. The heat radiation base has a plurality of spaced grooves formed on an inner side thereof for engagement of heat radiation fins of the heat radiation fin module. The heat radiation fins are respectively inserted in the grooves of the heat radiation base and compressed in the grooves by stamping so that the heat radiation fins are connected to the heat radiation base. The fan is located inside the heat radiation fin module and surrounded by the plurality of heat radiation fins. When the heat radiation base absorbs heat, the fan is started to dissipate heat quickly. At least one heat conduction pipe is connected between the heat radiation base and the heat radiation fin module to enhance the heat dissipation efficiency of the heat sink. |
