Patent ID: 7457122

Claim:
A memory module assembly comprising: a printed circuit board having an electronic heat-generating electronic component mounted on a first face of the printed circuit board; a first heat-dissipation plate comprising a first hook extending from a left side thereof and a second hook extending from an opposite right side thereof, the first hook comprising a resisting portion extending from an end of the first heat-dissipation plate and a first engaging portion extending from a free end of the resisting portion, for resisting the printed circuit board, the second hook comprising a section attached on a right end portion of a rear face of the first heat-dissipation plate, and a pair of locking portions extending from upper and lower ends of the section and clamping on upper and lower ends of the first heat-dissipation plate; and a second heat-dissipation plate defining a depressed portion in a left side thereof for engaging with said first hook; wherein a second engaging portion of the second hook and an oppositely opposed ear of the first and second heat-dissipation plates respectively, engage with each other to clamp the printed circuit board between the first and second heat-dissipation plates, and wherein the electronic heat-generating electronic component is thermally connected with one of the first and second heat-dissipation plates.
