Abstract
An electron discharge tube evaporation cooling system in which part of a tube to be cooled is immersed in coolant in a boiler (15), the cooling system further comprising a condenser (18) for vapor generated in the boiler (15), and a coolant reservoir (11). The flow of vapor from the boiler (15) to the condenser (18) experiences resistance in the interconnecting pipe (17), producing in the boiler (15) a back pressure dependent on the dimensions of the pipe (17). In order that a desired level (40) of coolant in the boiler (15) can be obtained for a range of back pressures, the coolant is supplied to the boiler via an overflow system (16) having an adjustable overflow level. The overflow system (16) comprises a chamber (31) open to atmosphere at the top (34) and having at the bottom (33) an opening (36) through which an overflow tube (35) passes. The opening (36) is provided with a liquid-tight gland (37) comprising a compressible ring (42) and a pressure member (43) adjustable to allow the tube (35) to be slid through or to lock it in position.
