Abstract:
A heat dissipation device coupling structure comprised of a heat sink and frame-type retaining tabs, characterized in that:the heat sink has a shoulder plate projecting outward from the lower base thereof, with the length of the shoulder plate being smaller than a positioner rod; the positioner rod is disposed on one side of the frame-type retaining tabs and L-shaped lock tabs are disposed on each two ends at the lower extent of the positioner rod which is elevated thereby forming a space accommodating the insertion of the shoulder plate of the heat sink; a seat section is situated at the opposite side of the positioner rod, having a stop tab at lower end thereof and tensile clip tabs curving outward from upper end thereof; a frame plate is situated at each of two other opposite sides thereof such that an opening formed by each of the frame plate corresponds to each end of the positioner rod is narrower than a wider opening formed by the L-shaped lock tabs and, furthermore, a lip tab is folded downwardly along the outer rims of the frame plate forming upper and lower containment recesses that enables a central processing unit and the heat sink inserting into the upper containment recess and the lower containment recess respectively; by providing such a structure, the heat sink and the central processing unit can be tightly assembled together easily and rapidly; conversely, disassembly is simple and accomplished by applying a slight force to spread the said clip tabs apart.
