CONDENSER INSTABILITY IN PRESSURE CONTROLLED HEAT PIPES
The vapour gas interface of pressure controlled heat pipes loses heat to the condenser. This heat is supplied by condensation of vapour, forming a mist which is supported by flow of vapour from below. Convecting gas transports vapour and mist to cool parts of the condenser where they liquefy and flow back past the interface. The balance of these flows is easily disturbed and regular fluctuations of the interface commonly occur, especially at low operating pressures. This accentuates transport of vapour via the gas, and solid condensate can form and isolate the heat pipe from the gas ballast, especially when the interface is well inside the condenser.
