Abstract 1,045,835. Capacitors. GENERAL ELECTRIC CO. Aug. 13, 1963 [Sept. 18, 1962], No. 31964/63. Heading H1M. In the capacitor shown in cross-section, the side walls 2a and 2b of casing 2 are flexible to respond to expansion or contraction of the dielectric fluid 15, and heat-conducting plates 11 and 12 having portions 11a and 12a in constant contact with the capacitor transfer heat therefrom to the end walls 2c and 2d of the casing. The inwardly bowed members 11 and 12 may also have portions projecting outwardly to contact side walls 2a and 2b to maintain the spacing between the conducting plates and the side walls, and the contact of the heat-conducting members with the capacitor unit. Alternatively, as in Fig. 4 (not shown), these results are achieved by appropriately located leaf or coil springs. Plates 11 and 12 may have apertures to facilitate circulation of the dielectric fluid and are preferably of metal having high thermal conductivity, e.g. aluminium. Outer casing 2 is preferably of metal, such as mild or stainless steel, having a coefficient of expansion lower than that of the plates 11 and 12. The capacitor unit shown comprises flattened rolls surrounded by insulation 10, the casing 2 being hermetically sealed by a cover. The dielectric fluid may be chlorinated diphenyl, insulating oil or sulphur hexafluoride.
