Abstract: A modularized computer servo working cabinet having side wall plates which are assembled by a plurality of unit pieces. A sliding track is installed in a proper position of each side wall plate on an inner portion thereof for receiving one or more main frame racks. The racks have a U-shape and feed track grooves installed thereon. Each unit piece is a large plate with notches and stopping portions installed thereon for assembling with assembling pieces and connecting pieces. Each assembling piece is a medium plate with a flange installed thereon for engaging with the stopping portion and with a plurality of assembling piece holes installed thereon for fixing the sliding track and locking with the connecting pieces. Each connecting piece is a small plate with at least one insertion portion having holes for engaging with the assembling pieces.

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.
