A heat radiator includes a base and heat radiating fins. The base has a surface formed with grooves for insertion of the heat radiating fins. Each heat radiating fin has a bent portion at one end thereof. The bent portion has spaced protrusions thereon. The bent portion is inserted and embedded in the groove of the base. Then, a press head is aligned with the bent portion for pressing. The press head has an inclined surface to cover the bent portion and a side wall of the groove. After pressing, the bent portion is deformed and enlarged to engage with the groove. The side wall of the groove is compressed by the inclined surface of the press head to be shifted and deformed. The deformed side wall holds against the bent portion, so that the heat radiating fins and the base are connected.
