Abstract:
A heat dissipation fixture seating structure for mounting a heat dissipation fixture and comprising:a) a central processing unit (CPU) housing having a surface with at least two through holes;b) a base plate having at least two notched sections, the base plate located on the surface of the CPU housing such that the at least two notched sections are aligned with the at least two through holes;c) at least one hold down having: a first section located on the base plate, the first section having two opposite ends; a catch seat having an inverted V-shaped configuration with a first leg extending from a first of the two opposite ends of the first section, and a second leg having a first inward latch hook thereon and a notched limiter section; and a hook seat having an inverted V-shaped configuration with a third leg extending from a second of the two opposite ends of the first section, and a fourth leg having a pair of slots and a second inward latch hook, the second and fourth legs extending through the notched sections of the base plate and the through holes of the CPU housing;d) at least one lifter link having an adjustment saddle with two adjustment arms extending therefrom, the adjustment arms extending through the notched limiter sections and having shank hooks thereon engaging the pair of slots; and,e) a threaded member threaded into and extending through the adjustment saddle into contact with the catch seat such that rotation of the threaded member causes deflection of the second and fourth legs toward each other, thereby urging the first and second inward latch hooks to clasp the CPU housing.
