Abstract:
1. A cooling module retentioner, comprising: a fixing base mounted on a circuit board to surround a heat-generating electronic component at a center, enabling a cooling module to be disposed in direct contact with said heat-generating electronic component, and having a rising corner column located at each of four corners thereof and equipped with a retention hole; and a flexible frame composed of two M-like retention brackets integrally combined with two connection bars, having a retention hook at each bottom end of said two M-like retention brackets for snapping in said retention hole of said fixing base respectively, and having a pivot part disposed at a lower central location of each of said two M-like retention brackets for pivotally mounting a lever being a metal rod and having a protruded portion formed by integrally bending one end of said lever; wherein said cooling module has at least two pressing portions for said two retention brackets to stride across, and a fixing hook of each said retention bracket corresponding to said respective lever is provided for positioning said respective protruded portion wherein said cooling module comprises a heat sink and a cooling fan, said heat sink is closely in contact with said heat-generating electronic component to directly absorb and conduct heat generated from said heat-generating electronic component, said heat sink has a plurality of cooling fins thereon, and a retention flange is formed on an inner side of each of two outmost cooling fins and said cooling fan is fixed on an integration base, a through hole is formed at a position corresponding to an air outlet zone of said cooling fan, the at least two pressing portions are projected outwardly from each of two opposite sides respectively, a plurality of hooks and a plurality of stoppers are disposed on a bottom side of said pressing portions, said plural hooks are engaged with said two retention flanges of said heat sink respectively, and said plural stoppers exactly block two ends of said retention flanges respectively.
