Abstract
An improved heat sink element coupling structure comprised of a minimum of one or more folded appendages that are formed by bending along the upper or lower lateral edges, the middle, or other suitable position of a single heat sink element or along the two sides of one lateral edge or middle position of a single heat sink element; an opening disposed at the confluence of the folded appendage and the single heat sink element plate that penetrates the folded appendage to form a perforated construct; and a linking member that extends outward from the folded appendage and, furthermore, is positioned at the distal extremity of the single heat sink element plate. The features of the present invention include the following innovations. The linking member also has two lock tabs along its two sides that extend from the two sides at the leading extremity of the linking member. During interconnection, the lock tabs along the two sides of the linking member on single heat sink elements are articulated into an O shape and engaged into the opening of another immediately adjacent single heat sink element. Furthermore, the linking member and the two lock tabs at its two sides are formed into a horizontal S shape or an inverted horizontal S-shaped arrangement such that they are crimped onto the other single heat sink element plate and also firmly secured against the two lateral edges of the opening to prevent unintentional dislodging.
Description
- 1) Field of the Invention
- The invention herein relates to heat dissipation fixtures, specifically an improved heat sink element coupling structure capable of total mechanical engagement that cannot be unintentionally dislodged, the coupling structure of which is disposed on a single side of each heat sink element to interconnect a plurality thereof into a heat sink.
- 2) Description of the Prior Art
- In conventional “assembly-type” heat sinks, such as those disclosed in patent application No. 407753, 460110, 468931, 484704, and 516794 in the Taiwan Patent Bulletin, the coupling structure for achieving interconnection consists of a “stack fit” approach. As a result, a coupling structure must be disposed at the upper and lower edge of each individual heat sink element plate so they can be interconnected into a heat sink. If the coupling structure is only disposed on the lower lateral edge of every individual heat sink element plate, but not on the upper lateral edge, they cannot be conjoined to the heat sink mounting plate. Since the coupling structure of conventional head sink must be situated on the upper and lower edge of each single heat sink element plate, only rectangular shaped heat sinks can be assembled which seriously limits profile variety and performance range. Additionally, since the coupling structure of the said conventional heat sink only consists of a “stack fit” approach for interconnection that is not “fully engaged”, loosening and/or dislodging easily occurs during assembly or when installed and utilized, demonstrating that the prior art is entirely impractical. In view of the said situation, the two applicants of the invention herein conducted extensive research and testing to develop the improved heat sink element coupling structure of the present invention.
- The objective of the invention herein is to provide an improved heat sink element coupling structure capable of total mechanical engagement that cannot be unintentionally dislodged and, furthermore, that is not easily loosened nor shifted during assembly or while installed and in use.
- Another objective of the invention herein is to provide an improved heat sink element coupling structure, wherein only one or more coupling structure on the lateral edge of single heat sink elements enable interconnection into a heat sink.
- The improved heat sink element coupling structure of the invention herein is comprised of a minimum of one or more folded appendages that are formed by bending along the upper or lower lateral edges, the middle, or other suitable position of a single heat sink element or along the two sides of one lateral edge or middle position of a single heat sink element; an opening disposed at the confluence of the said folded appendage and the said single heat sink element plate that penetrates the said folded appendage to form a perforated construct; and a linking member that extends outward from the said folded appendage and, furthermore, is positioned at the distal extremity of the said single heat sink element plate, the features of which are: The said linking member also has two lock tabs along its two sides that extend from the two sides at the leading extremity of the said linking member; during interconnection, the lock tabs along the two sides of the linking member on a said single heat sink element are articulated into an O shape and engaged into the opening of another immediately adjacent single heat sink element and, furthermore, the said linking member and the said two lock tabs at its two sides are formed into a horizontal S shape or an inverted horizontal S-shaped arrangement such that they are crimped onto the said other single heat sink element plate and also firmly secured against the two lateral edges of the opening to prevent unintentional dislodging. As such, during assembly or while installed and in use, the present invention is not easily loosened or unintentionally dislodged; at the same time, since only one lateral edge of the single heat sink elements enables interconnection for assembling heat sinks, they can be connected into an inclined plane-type, notched or variable height, wave-shaped heat sinks, or even connected into cylindrical-type, rectangular, tubular, ovoid tubular-shaped, polygonal tubular-shaped heat sink; and also connected to single heat sink element plates having differing heights (widths) to assemble an unevenly profiled heat sink, thereby accommodating a range of varying arrangements to meet the different design requirements and demands of manufacturers.

FIG. 1 , the isometric drawing of the invention herein, the drawing depicts acoupling structure 11 at the left corner section on the upper edge of a singleheat sink element 1plate 10 that is symmetrically or correspondingly disposed on thecoupling structure 11 at the right side of the lower edge or the left or right side of the lower edge of the said singleheat sink element 1plate 10. The saidcoupling structure 11 is comprised of a minimum of one or more foldedappendages 12 of appropriate length that are formed by bending along the upper or lower edge, the middle, or other suitable position of the singleheat sink element 1plate 10; anopening 121 disposed at the confluence of the said foldedappendage 12 and the said singleheat sink element 1plate 10 that penetrates the said foldedappendage 12 to form a perforated construct; and a linkingmember 13 that extends outward from the said foldedappendage 12 and, furthermore, is positioned at the distal extremity of the said singleheat sink element 1plate 10. The said linkingmember 13 also has twolock tabs 131 along its two sides that extend from the two sides at the leading extremity of the said linkingmember 13. - Referring to
FIG. 3 , the improved structure heat sink element coupler is pictured in a flat state when fed as material during the first step of the punch fabrication process, wherein the fed material consists of the foldedappendage 12 of thecoupling structure 11, itsopening 121 as well as the linkingmember 13lock tabs 131 along its two sides, that is contiguous to one lateral edge of theheat sink element 1plate 10; next, as indicated inFIG. 4 , thelock tabs 131 along the two sides of the linkingmember 13 at the outer side of the said foldedappendage 12 are punched into an O shape in preparation for the interconnection of each singleheat sink element 1plate 10, as shown inFIG. 2 , wherein when a few or numerousheat sink elements 1 are actually interconnected, thelock tabs 131 along the two sides of the linkingmember 13 must be articulated into a O shape before the foldedappendage 12 is bent along the one lateral edge of the said singleheat sink element 1plate 10, with the bend executed such that it is perpendicular to the saidheat sink element 1plate 10 in the manner shown inFIG. 4 ; as the foldedappendage 12 is bent, thelock tabs 131 along the two sides of the linkingmember 13 at its outer side, as shown inFIG. 2 , are fitted into theopening 121 through the foldedappendage 12 of the singleheat sink element 1 in front, the said twolock tabs 131 are pressed into a horizontal S shape or an inverted horizontal S-shaped arrangement by a downward tooling stroke to complete the interconnection of each singleheat sink element 1plate 10 to another singleheat sink element 1plate 10. The said twolock tabs 131 are also crimped onto the said singleheat sink element 1plate 10 to the front and both are also firmly secured against the two lateral edges of theopening 121 in the foldedappendage 12 of the said front singleheat sink element 1 such that they are not easily loosened and, furthermore, cannot be unintentionally dislodged; the said punch fabrication task consists of a continuous punch press and molding process and, with the exception of the material feed and punch fabrication steps, each punch executed thereafter fashions aheat sink element 1 and completes the interconnection of theheat sink element 1 to the front in a punching process that is quite simple and quick which facilitates rapid mass production. - Referring again to
FIG. 5 , since thecoupling structure 11 is capable of total mechanical engagement, not easily loosened and, furthermore, cannot be unintentionally dislodged following the interconnection of each singleheat sink element 1plate 10, alock tab 131 is only needed on one side, either the left side or the right side, at the leading extremity of the linkingmember 13, to similarly enable the efficient interconnecting of two singleheat sink element 1plates 10. - Referring to
FIG. 6 , the drawing illustrating another different embodiment of thelock tabs 131 a on the two sides of the linkingmember 13 of thecoupling structure 11 of the invention herein, the flat, rectangular orU-shaped lock tabs 131 shown inFIG. 1 are modified intotriangular lock tabs 131 a, similarly enabling the efficient interconnecting of two singleheat sink element 1plates 10. - Finally, referring to
FIG. 7 ,FIG. 8 ,FIG. 9 ,FIG. 10 , andFIG. 11 , based on the general embodiment herein, when thecoupling structure 11 of the invention herein is likewise disposed on the upper and lower edges of singleheat sink element 1plates 10, they can be connected, as indicated inFIG. 7 , into a conventionalrectangular heat sink 2; when thecoupling structure 11 of the invention herein is disposed on the lower edge or only on one lateral edge of singleheat sink element 1plates 10, then they can be connected into an inclined plane-type heat sink 2 a (as shown inFIG. 8 ), or notched, variable height, or wave-shaped heat sink 2 b (as shown inFIG. 9 ), or even connected into a cylindrical-type heat sink 2 c (as shown inFIG. 10 ) or a rectangular, tubular, ovoid tubular-shaped, or polygonal tubular-shaped heat sink (not shown in the drawings); and also connected, as shown inFIG. 11 , to singleheat sink element 1plates 10 having differing heights (widths) to assemble an unevenly profiled heat sink, thereby accommodating a range of varying arrangements to meet the different design requirements and demands of manufacturers.
