  • Patent number: 6687125
    Abstract: In a cooling system for an integrated circuit chip, by including an evaporator contacted-combined with an integrated circuit chip installed onto a board and absorbing heat generated at the integrated circuit chip; a compressor connected to the evaporator by a first connection pipe; a condenser connected to the compressor by a second connection pipe; an expansion means connected to the condenser by a third connection pipe and simultaneously connected to the evaporator by a fourth connection pipe; and a mounting board installed onto the board by a board combining means and mounted with the compressor, the condenser and the expansion means, it is possible to perform the operation of the integrated circuit chip smoothly, and accordingly a reliability of a product can be improved. In addition, although an integrated circuit chip is getting even more integrated, cooling of the integrated circuit chip can be efficiently performed.
    Type: Grant

  • Patent number: 6611989
    Abstract: A vacuum cleaner has a case including a dust chamber filtering dust included in air, an appliance chamber sucking the filtered air from the dust chamber and discharging the air through a discharge port, and a cord chamber storing a wound electrical cord. A fan motor assembly is installed inside the appliance chamber of the case for forcedly sucking the air inside the appliance chamber and discharging the air. An exhaust duct is installed between the fan motor assembly and the discharge port in the case and guiding the air discharged from the fan motor assembly to the discharge port, and a flowing passage is disposed between the dust chamber and the cord chamber so that the air is able to flow therein, whereby overheating of case and of the electrical cord can be prevented and the durability and reliability of the cleaner can be enhanced.
