A heat-dissipating device with heat conductive tubes comprises a heat-dissipating unit having plurality of fins; each fin having a plurality of through holes; each through hole having a corresponding via hole near the through hole; a plurality of annular walls being arranged around each through hole; and a plurality of heat conductive tubes passing through respective through holes of the fins. In manufacturing, the plurality of heat conductive tubes and the heat-dissipating unit with press bars are positioned to a fixture; a shaping mold serves to punch the press bars so that the press bar to press the side walls and thus the fins are tightly riveted to the heat conductive tubes.
