  • Cooling system of electronic computer using flexible members in contact with semiconductor devices on boards
    Patent number: 5504924
    Abstract: An electronic computer cooling system having a cooling apparatus to cool an electronic computer and cooling members for thermally connecting semiconductor devices whose operating speeds are raised by cooling to a low temperature source of the cooling apparatus. Circuit boards onto which the semiconductor devices and the like constructing the electronic computer are mounted and the cooling apparatus such as a refrigerating apparatus and the like are compactly enclosed in a single casing. Or, the circuit boards and the cooling apparatus are compactly enclosed in separate detachable casings, respectively. Thus, a structure in which desired semiconductor devices can be certainly cooled by using the cooling members is obtained.
