1,126,265. Cooling systems. COMPAGNIE FRANCAISE THOMSON HOUSTON-HOTCHKISS BRANDT. 7 July, 1966 [7 July, 1965], No. 30495/66. Heading F4U. A cooling system comprises an enclosure containing a vaporizable liquid and having one wall which is adapted to be exposed to a source of heat, internal projection on said one wall, means for sub-cooling the liquid so that vapour formed adjacent the projections will condense in the body of liquid and elastic means exposed to the liquid for damping pressure fluctuations caused by the vaporization and condensation process. As shown, an annular enclosure 3 surrounds a cylinder 1, e.g. the anode or collector of an electron discharge tube or the cylinder of an I.C. engine, having projections 5, the liquid in the enclosure is sub-cooled by a coil 6 and the elastic means comprises a partly inflated flexible annular body 20. A screen 21 and a filling hole having a stopper 10 are provided. The liquid may be sub-cooled externally of the enclosure (Figs. 5 and 6, not shown) and the screen may be perforated (Fig. 6). The cylinder to be cooled may be closed at one end and the surrounding enclosure bell-shaped (Figs. 1, 7 and 10, not shown). The elastic means may be partspherical and contained in either the enclosure (Fig. 1) or in a sub-chamber screwed into the filling hole in place of the stopper (Fig. 2, not shown); the sub-chamber may alternatively contain a flexible diaphragm (Fig. 3, not shown). In further embodiments (Figs. 7 and 10) the elastic means comprises a vapour pocket at the top of the enclosure. Formulµ for determining the configuration of the internal projections are given. |
