Abstract
A radiating fin and a method of manufacturing the same are disclosed. The radiating fin includes a main body having a first side and an opposite second side, and being provided with at least one through hole to extend between the first and the second side for a heat pipe to extend therethrough; and at least one extension being formed on at least one of the first and the second side of the main body to locate around the at least one through hole and axially project from the main body. The extension is crimped to form a plurality of circumferentially alternate ridge portions and valley portions for tightly pressing against an outer surface of the heat pipe, so as to firmly bind the radiating fin to the heat pipe. A thermal module can be formed by sequentially binding a plurality of the radiating fins to the heat pipe.
