  • Patent number: 6798655
    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.
    Type: Grant
