A new method of cooling high-power valves by vaporization of water

The problem of disposing of the heat generated in the anodes of high power valves is discussed, and brief reference is made to the different methods of construction adopted in valves of this class. Existing methods of cooling are examined and their limitations stated. The mechanism of transfer of heat from a copper anode to the surrounding water is considered, and its application to valve cooling is discussed. A new method of cooling by vaporization of water is then dealt with. Consideration is given to the construction of vapour cooled valves, followed by an explanation of the complete system.
