Claim:
1. A method of manufacturing heat dissipation device, comprising the following steps: providing a single L-shaped mounting bracket having at least one retaining hole and a mounting section; providing a thermal module including a plurality of radiating fins for engaging with the L-shaped mounting bracket; on one lateral side of the plurality of radiating fins, at least one engaging zone being recessed from the lateral side perpendicular to each of the plurality of radiating fins and formed for correspondingly engaging with the L-shaped mounting bracket, and at least one locking portion being formed for correspondingly engaging with the at least one retaining hole on the L-shaped mounting bracket, wherein the locking portion and the radiating fin are integrally molded; and positioning the L-shaped mounting bracket in the engaging zone from the lateral side of the radiating fins, and applying an amount of pressure on the at least one locking portion, so that the locking portion is deformed sufficiently to be allowed to extend into and become held in the retaining hole on the L-shaped mounting bracket, bringing the L-shaped mounting bracket and the thermal module to connect to each other to form the heat dissipation device.
