Title:
真空可変キャパシタおよび冷却方法
Document Type and Number:
Japanese Patent JP7144439
Kind Code:
B2
Abstract:
A variable vacuum capacitor is described in which oil inside the main bellows 21 is pumped through the bellows and through the oil circuit 8 of a heat exchanger by a pump 15. Water passes through coolant channels 6 of the heat exchanger, from inlet 7 to outlet 7'. The extendable capacitor drive shaft 14 is hollow and serves as a conduit, conveying the oil to the bottom of the bellows 21, thereby ensuring a full circulation of the oil right through the bellows and then through the heat exchanger. Pump drive means 9 may be a gerotor hydraulic motor, coupled to a gerotor oil pump 15 via magnetic coupling 22. Pumping heat transfer fluid (oil) through the bellows allows the capacitor to operate at significantly higher currents and/or lower temperatures, and significantly extends the life of the device.
