Patent ID: 7286364

Claim:
A heat dissipating device for a memory chip; the heat dissipating device being installable to a surface of a circuit board for fixing a memory chip on the circuit board; the circuit board having a plurality of penetrating holes; positions of the penetrating holes being at a periphery of the memory chip to be positioned on the circuit board; the heat dissipating device comprising: a rectangular heat dissipating body having a rectangular recess at a center portion thereof; each side of a periphery of the recess being formed with a plurality of through holes; a middle section of each of two opposite sides of the heat dissipating body having a wall and a hook being extended from the wall to point away from the heat dissipating body 10 ; a distal end of each hook being bent as a hooking end; an outer side of the bending section being chamfered as a guiding angle; the walls being between the hooks and the heat dissipating body and being wider than the hook for enhancing the strength and the elasticity of the hooks; thus, the hooks can be extended and can be made thinner; and each of four corners of the heat dissipating body being extended with a protrusion which is bent from the heat dissipating body to have the same orientation as the hook; and wherein in assembly, the hooks is hooked to the penetrating holes so that the recess will cover upon the memory chip; heat from the memory chip will dissipated from the penetrating holes; the guiding angles between the hook and the hooking ends assists the hooks passing through the penetrating holes in assembly; and the protrusions serves to catch the memory chip so as to position the memory chip.
