Abstract
887,568. Semi-conductor rectifiers. GENERAL ELECTRIC CO. Ltd. June 8, 1959 [June 6, 1958], No. 18140/58. Class 37. Semi-conductor devices, e.g. power rectifiers, of the kind having electrodes formed by blocks of high thermal and electrical conductivity and cooled by cooling fluid, are mounted in communication with apertures in a support comprising a duct for cooling fluid, and removable inserts direct the cooling fluid from the duct to the base electrodes and back into the duct. As shown, one electrode of a rectifier 6 is constituted by a hollow cylindrical block of copper closed at the end bearing the semi-conductor, e.g. germanium, body, and is clamped by means of a captive nut 7 on to a tube 4 of brass or copper which is brazed or screwed to a hollow copper bus-bar 1, the bore of the tube 4 communicating with the duct 2 in the bus-bar 1 by means of an aperture in the latter. A tubular insert 9 extending from the duct 2 into tube 4 is fixed in the latter by a screw-threaded sleeve 17 bearing down on a perforated circumferential fin 14 on the insert 9. The end of the insert 9 within the duct 2 is closed, and a side opening 13 faces upstream of the flow of cooling fluid in the duct so that the fluid passes up the bore 10 of the insert 9 to cool the base electrode and back to the duct 2 via an annular passage 11 between tube 4 and insert 9. In this way, a plurality of rectifiers mounted on bus-bar 1 are cooled in series. In a modification, the hollow bus-bar 1 is replaced by a solid bus-bar brazed to a pipe ; alternatively, the bus-bar, pipe, and tube 4 are cast together as an integral unit. Reference has been directed by the Comptroller to Specification 859,849.
