Abstract
Abstract A heat-radiator for CPU of a computer, mainly including an air exhaust box, a collection funnel means and a bellows connecting the air exhaust box with the collection funnel means. An air blower and a detector means are disposed in the air exhaust box and connected by a circuit interface board inserted in an interface socket of the computer. The collection funnel means includes a heat-radiating plate located on the CPU, whereby the heat generated by the CPU is conducted through the heat-radiating plate and radiated therefrom to the ambient air and the hot air in the collection funnel means is sucked by the air blower to flow through the bellows and the air exhaust box to be exhausted from the computer housing.

Total Claims: 13
Claim 1
Independent Claim
273 words
A heat-radiator for CPU of a computer, comprising an air exhaust box, a collection funnel means and a bellows connecting said air exhaust box with said collection funnel means, said heat-radiator being characterized in that: said air exhaust box is disposed with an air exit at a first end and an air incoming pipe at a second end, an air blower being disposed at said first end and a circuit interface board being disposed in said air exhaust box to connect with a detector means and said air blower, said circuit interface board being inserted into an interface socket of the computer for power supply; and said collection funnel means includes a collection funnel which has a hollow circular tube downward extending from a top portion of said collection funnel for a first spring to fitted therearound so as to abut against a heat-radiating plate, on two lateral sides of said collection funnel being respectively formed two bosses and slide rails located thereunder, on other two lateral sides of said collection funnel being formed two pairs of latch holes, an air outgoing pipe being disposed on one of said lateral sides for said bellows to fit therewith, two opposite symmetric clamping casings being slidably disposed on said slide rails of said collection funnel, said clamping casings respectively having two tenons on outer sides thereof, whereby a second spring is hooked between the tenons to tightly associate said clamping casings together, said clamping casings further respectively having two opposite hooking sections downward extending from bottom ends thereof for hooking/clamping the CPU, a pushing member being pivotally disposed on said bosses of said collection funnel.
