Patent ID: 7077188

Claim:
A method for forming a heat dissipating device with heat conductive tubes by using a shaping mold; a bottom of the shaping mold having a press plate; a plurality of springs being installed between the press plate and the shaping mold; the press plate having a plurality of through holes; the shaping mold having a plurality of punching plates extending thereform; and a heat dissipating device with heat conductive tubes comprising: a heat dissipating unit including a plurality of fins; a bottom edge of each fin having a plurality of concave portions; a seat; a surface of the seat having a plurality of protruding surfaces; a top of the seat having a plurality of trenches; a plurality of recesses being vertically passing through the plurality of trenches; the concave portions being formed corresponding to the trenches so that the fins are inserted into the recesses so that the concave portions cover upon the trenches; a plurality of heat conductive tubes; one end of each heat conductive tube being installed between one respective trench and respective concave portions of the plurality of concave portions; the method comprising the steps of: passing the punching plates through the through holes of the press plate to enter into the space between the fins; and punching the punching plates upon the protruding surfaces at portions between two fins so as to press the protruding surfaces at two sides of the fins to compress the fins; as a result the fins are tightly clamped within the recesses; thereby, heat dissipating unit being riveted in the seat.
