A cooling apparatus for an electronic device of high calorific density including an elastomer interposed between a semiconductor chip and a heat sink so as to connect them thermally. The elastomer may also be in close contact with a large number of semiconductor chips having various configurations which are mounted on a board, so that the elastomer is thermally connected with them, whereby the elastomer absorbs thermal deformations.
摘要:
A semiconductor cooling unit for directly jetting a cooling medium against surfaces of semiconductor devices for use in a high-speed computer or the like to effectively remove heat from the semiconductor devices, in which partition members for partitioning a space into regions where semiconductor devices are placed. Each partitioned region has an opening at its ceiling side, and a pipe for supplying or discharging the cooling medium through the opening is disposed so as to project toward a central portion of the back surface of each semiconductor device. This pipe is utilized to also section a cooling medium supply header or a cooling medium return header so that bubbles generated from the semiconductor device surfaces can be smoothly removed, and so that the cooling medium can flow smoothly onto the semiconductor devices.

High heat generation member of electronic integrated circuit etc. is boiled and cooled. A refrigerant steam is generated by cooling of the heat generation member and is condensed by a condenser which is provided an upper portion. A refrigerant steam flow path and a condensed refrigerant flow path from the condenser are separated with a partition wall. The condensed liquid sent back to the partition wall is supplied to the heat generation member through the partition wall.

An arc extinguishing device of a gas circuit breaker includes: an arc chamber in which an arc generated between a movable electrode and a fixed electrode is formed; a heat puffer chamber disposed so as to surround the arc chamber; a blow port in which the arc chamber communicates with the heat puffer chamber in the circumferential direction of the arc chamber; hydrogen absorbents which are disposed on an inner wall of a pressure chamber; an exhaust port which passes to the outside of an arc extinguishing chamber; and a hydrogen absorbent disposed at a position surrounding the movable electrode. Deterioration of insulation due to a product formed by decomposition of arc extinguishing gas by the arc during a contact opening operation can be suppressed.
