Abstract
Abstract A dissipating structure for central processing unit chip includes a frame, a fixture, a felt board, a dissipating board, and a fan, wherein an open end of the fixture is rotatably secured to the frame. The rest edges of the fixture are formed like holding portion adapted to hold the chip, the felt board, and the dissipating board in place, sequentially. A plurality of dissipating elements are formed on the dissipating board adapted to dissipate heat created by cpu chip. Four dissipating blocks are formed at four corners of the dissipating board each having an aperture adapted to secure the fan thereon by means of screws.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
154 words
A dissipating structure for central processing unit chip comprising: a frame of a square strip having an annular flange at inner perimeter resting the edges of a cpu chip, a plurality of circumferentially spaced blocks extending upwardly one side thereof, two lugs extending from one edge, and two protuberances; a dissipating board being shaped like said cpu chip having a plurality of dissipating elements fastened on top thereof, which includes at least four blocks at four corners each having an aperture adapted to fasten a fan thereon, two grooves at respective sides; a clip being made from a flexible metallic material and bent into shape having an open end rotatably hinged to said lugs of said frame, holding portions at rest edges and a finger grip; a felt board being shaped like said cpu chip adapted to prevent said dissipating board from slippery and to dissipate heat created by said cpu chip as well.
Claim 2
Dependent Claim
