Water-cooled cooler for CPU of PC

Abstract

A device for cooling a CPU of PC comprises parallel tubes interconnected top and bottom, fins mounted on an outer surface of each tube, and a fan for cooling the fins; and a reservoir assembly including a first reservoir on a top, a second reservoir separate from the first reservoir, an inlet provided on the first reservoir, a third reservoir on an underside, a fourth reservoir separate from the third reservoir, and an outlet provided on the fourth reservoir. Water flowing through the hot CPU is adapted to enter from the inlet to flow through the first reservoir, a first number of the tubes, the third reservoir, a second number of the tubes, the second reservoir, a third number of the tubes, and the fourth reservoir prior to leaving the device via the outlet.

1 . A device for cooling a CPU of a PC comprising: 
 a cooling assembly including a top plate, a bottom plate, a plurality of parallel tubes interconnected the top and the bottom plates, a plurality of fins mounted on an outer surface of each of the tubes for absorbing heat of water flowing through the tubes, and a fan for generating air flow to cool the fins; and    a reservoir assembly including a first reservoir on a top, a second reservoir separate from the first reservoir by a first gap, an inlet provided on the first reservoir, a third reservoir on an underside, a fourth reservoir separate from the third reservoir by a second gap, and an outlet provided on the fourth reservoir wherein the first reservoir is in fluid communication with the third reservoir via a first number of the tubes, the third reservoir is in fluid communication with the second reservoir via a second number of the tubes, and the second reservoir is in fluid communication with the fourth reservoir via a remaining third number of the tubes respectively;    wherein water flowing through the hot CPU is adapted to enter from the inlet to flow through the first reservoir, the first number of the tubes, the third reservoir, the second number of the tubes, the second reservoir, the third number of the tubes, and the fourth reservoir sequentially prior to leaving the device via the outlet.    
   
   
       2 . The device of  claim 1 , wherein the top plate comprises an upper connecting member proximate one side of the cooling assembly for connecting the first reservoir to the second reservoir, and the bottom plate comprises a lower connecting member proximate the other side of the cooling assembly for connecting the third reservoir to the fourth reservoir.
