Abstract: In a method of forming bent heat dissipating unit, the following steps are included: putting a plurality of radiating fins on and around a straight heat pipe to form a heat dissipating unit; engaging the heat dissipating unit with a forming die assembly, so that a plurality of locating die units sequentially arranged on a carrier of the assembly are separately positioned in a space between two adjacent radiating fins; pressing the engaged heat dissipating unit and forming die assembly against a forming block; and driving a processing machine connected to the carrier of the forming die assembly to change the arrangement of the locating die units and thereby bend the heat dissipating unit to a shape corresponding to a profile of the forming block. An apparatus for forming the bent heat dissipating unit through the above steps is also provided.

Abstract: A structure for connecting radiating fins includes a plurality of parallelly arranged and vertically spaced radiating fins and at least one connector. Each of the radiating fins is provided on at least one outer edge with at least one receiving section, so that at least one group of aligned receiving sections is formed. The connector is lengthwise provided with a plurality of spaced engaging sections corresponding to the number of and the space between the radiating fins, and is positioned in the group of aligned receiving sections to thereby extend across and hold the parallelly arranged and vertically spaced radiating fins in place.
