Abstract

A radiator shaping device comprises a lower mold, an upper mold, and two movable molds. The lower mold is installed with a lower chamber; The upper mold installed with an upper chamber, after the lower mold and the upper mold are engaged, a closing space is formed therewithin. The movable molds having a plurality of inserting plates which serves to insert into the fins at two ends of an aluminum folded radiating piece so as to support the folded radiating piece from the two ends thereof. Then it is further placed into the closing space for separating the space as a lower space and an upper space. Next, aluminum liquid is filled into the filling hole of the upper mold. After cooling, the mold is detached, therefore, a high heat dissipating radiator with a lower plate integrally formed in the lower surface of a folded radiating piece is formed by above components. Especially, by the shaping device of the present invention, the aluminum folded radiating piece and the lower plate can be combined together and have identical property. Thus, the heat conductive glue or other material for adhesion is unnecessary. Thus, heat conduction is more rapid, directly and steadily. The defect of prior art radiator in which glue connection is adapted is overcome by the present invention.

Dependent claims

A radiating device forming assembly comprising:

(a) a lower mold;
(b) an upper mold coupled to said lower mold to substantially enclose an inner chamber therebetween, one of said upper and lower molds having formed therein a filling hole communicating with said inner chamber;
(c) an aluminum radiating piece disposed within said inner chamber, said radiating piece having longitudinally opposed end portions, said radiating piece having a corrugated contour defined by a plurality of substantially parallel fin sections each extending longitudinally between said end portions, adjacent ones of said fin sections defining therebetween a longitudinally extending slot;
and,
(d) first and second movable molds respectively engaging said end portions of said radiating piece, each said first and second movable mold including a plate portion and a plurality of spaced inserting plates projecting longitudinally therefrom, each said inserting plate inserting into one said radiating piece slot, terminal ends of said first movable mold inserting plate respectively engaging in longitudinally opposed manner terminal ends of said second movable mold inserting plates to thereby partition in said inner chamber substantially isolated upper and lower spaces;
whereby a molten aluminum may be introduced through said filling hole into one of said upper and lower spaces and thereafter solidified to integrally form a radiating device having said fin sections projecting at least partially therefrom.
