ABSTRACT:
A CPU casing structure includes a casing body having a rear wall on which a side wall is mounted to define an open front side for receiving a nonpackaged a CPU therein. A heat dissipator having a base positionable over and in physical contact engagement with the CPU to provide heat transfer therebetween is releasably secured to the front opening of the casing body by means of at least one clip so as to substantially cover the front opening and thus house the circuit board and the CPU therein. The casing body has at least one clip anchoring members formed on the top edge thereof. The clip have a central section selectively postionable on the base of the heat dissipator and a fixed, but preferably resilient, end extension extending through holes formed on the casing body, the circuit board and the heat dissipator. The end extension has a bending on the free end thereof and the bending is formed as an acute angle to be received within a sloped cavity having an inclination of substantially the same angle formed on the casing body. The clips also have a movable extension defined by a hinged tab having a slot engageable with the respective anchoring member to secure the clips and thus fix the heat dissipator to the casing body together.
