Abstract:
1. A method of manufacturing radiating module, comprising the steps of: a. forming coaxial upper through holes and lower through holes on a plurality of radiating fins, such tat each of said upper and lower through holes has an annular flange axially extended toward the same side of said radiating fins; b. successively and parallelly arranging said radiating fins, so that a space equal to an axial length of said annular flange is left between any two adjacent radiating fins to serve as an air passage, and said coaxial upper and lower through holes form several lows of hollow paths on said radiating fins; c. extending two ends of a plurality of U-shaped heat-transfer tubes into said hollow paths formed from said coaxial upper and lower through holes, so that said radiating fins are connected to said heat-transfer tubes; and d. connecting a scat to said heat-transfer tubes, so that said seat is in contact with a bottom surface of said radiating fins.
