Abstract

866,117. Cooling discharge tubes; nuclear fuel elements. COMPAGNIE FRANCAISE THOMSON-HOUSTON. Aug. 6, 1957 [Aug. 6, 1956], No. 24767/57. Classes 39(1) and 39(4). [Also in Group XXXIII] In an arrangement for removing heat from a hot surface such as the anode of an electric discharge tube or a nuclear fuel element, the surface is shaped to present one or more concave channels which or each of which accommodates or in part defines a tubular duct for cooling liquid, the duct having means whereby the cooling liquid as it flows therethrough is given a rotational movement such that a central cavity is formed which serves for the evacuation of vapour formed on the duct wall and induced by the centrifugal pressure of the rotating liquid to pass into the cavity. The channel formed in the surface is opensided and may either be closed by a cover to define the coolant duct or a separate coolant duct may be fitted into the channel. The coolant liquid may be caused to flow through the duct under pressure or by thermosyphon action. In the application of the invention to a tubular fuel element in a nuclear reactor such as is shown in Fig. 9 the channels are formed between heat dissipating ribs 20, the open sides of the channels being closed by cover plates such as indicated by 16 in Fig. 4, or 18 in Fig. 5 embodying deflector means 17 for imparting rotational movement to the coolant flowing through the channels. In addition the internal bore of the element is provided with a helical deflector 10. In the application to the cooling of the anode of an electric discharge tube, Fig. 4 shows cooling liquid ducts formed on the exterior thereof by grooves 14 in the anode which are closed by core members 16 having deflector means 17 thereon for imparting rotational movement to the liquid. The deflector means may alternatively comprise a helical wire or rod or a helical strip. The core member may be formed by a continuous sleeve 18 (Fig. 5) surrounding the anode. The cross-sectional area of the duct may be greatest at the vapour outlet end (Fig. 6 not shown). In a further Form (Fig. 11) an annular groove 22 may be formed within or as shown around the anode 21 the groove being closed by a cover 24 thus defining the duct to which cooling liquid is admitted through one or more tangential inlets 25, vapour being removed at 26. The surface of the groove 22 may be scored or roughened or provided with inclined projections 23.
