  • Publication number: 20030128511
    Abstract: A desk-top type computer with a built-in LCD includes a chassis, a planar display attached to the chassis, a mother board attached to the chassis, heat generating portions including a CPU mounted on the mother board, and a memory device electrically connected to the mother board. A heat receiving head is fixed to at least one of the heat generating portions including the CPU, and the head is connected a tube filled with a cooling liquid. The tube is arranged in a serpentine or zigzag shape in a clearance between the chassis and the planar display facing the chassis. The cooling medium liquid circulating in the tube serves as a heat transferring medium to absorb the heat at the heat generating portion, and radiate the heat through the tube disposed in the clearance between the LCD and the chassis.

  • Publication number: 20030081380
    Abstract: In a liquid-cooling system for a notebook personal computer having a body part including a CPU and a chip set respectively mounted on a mother board and an HDD, and a display part rotatably supported by the body part, a heat receiving head is fixed to at least one heat generation part including the CPU. A tube filled with cooling liquid is connected to the heat receiving head. The tube connected to the heat receiving head is disposed in series on at least one heat generation part including the chip set so as to collect the heat generated from each heat generation part. The tube is also laid in a meandering or zigzagging pattern between a liquid crystal panel and a housing of the display part. The heat generated from each heat generation part is absorbed at part of the tube by the cooling liquid that circulates in the tube and functions as a heat transfer medium. The absorbed heat is then radiated at another part of the tube.

  • Publication number: 20020091468
    Abstract: In an information processing apparatus, a heat-generating portion including at least a CPU is cooled by circulation of a cooling liquid, the temperature of the cooling liquid is measured and the operating condition of a pump for circulating the cooling liquid is obtained in accordance with the measured temperature of the cooling liquid. The pump is operated on the basis of the operating condition to control the flow rate of the circulated cooling liquid. Further, even after the system for the information processing apparatus stops, the circulation of the cooling liquid is continued until the temperature of the heat-generating portion becomes not higher than a predetermined value.

  • Publication number: 20020075648
    Abstract: In an information processing apparatus such as a space-saving type personal computer having a liquid-cooling type cooling system, the presence of a cooling liquid, a freeze of the cooling liquid and the temperature of the cooling liquid are detected. When a freeze of the cooling liquid is detected, a CPU is throttled down to defrost the cooling liquid or the cooling liquid is heated to be prevented from being frozen. Alternatively, a warning of detection of a freeze may be indicated. Alternatively, the activation of the system may be stopped or the operation of the system may be interrupted. By such measures, system failure is prevented from being caused by leaking, shortage, freezing, etc. of the cooling liquid.

    Abstract: In an information processing apparatus such as a space-saving type personal computer having a liquid-cooling type cooling system, the presence of a cooling liquid, the presence of a frozen state of the cooling liquid and the temperature of the cooling liquid are detected. When a freeze of the cooling liquid is detected, a CPU is throttled down to defrost the cooling liquid, or the cooling liquid is heated to be prevented from being frozen. Alternatively, a warning of detection of a freeze may be displayed. Alternatively, activation of the system may be stopped or operation of the system may be interrupted.
