Abstract
A heat radiator useful for expelling waste heat from a power generating system aboard a space vehicle is disclosed. Liquid to be cooled is passed to the interior of a rotating bubble membrane radiator, where it is sprayed into the interior of the bubble. Liquid impacting upon the interior surface of the bubble is cooled and the heat radiated from the outer surface of the membrane. Cooled liquid is collected by the action of centrifical force about the equator of the rotating membrane and returned to the power system. Details regarding a complete space power system employing the radiator are given.
Claims6
A radiator system for removing waste heat in two phase fluids, suitable for use in space, comprising a rotating heat conductive membrane enclosing a volume which volume possesses an inner surface and an outer surface, the outer surface being capable of radiating heat;
- means for applying two phase fluid to be condensed to said inner surface;
- and means for collecting condensate fluid from said inner surface.
A method for removing waste heat from two phase fluids in space comprising the steps of:
- rotating a membrane which encloses a volume, said membrane having an outer surface and an inner surface;
- spraying two phase fluid which condenses upon the inner surface of a said membrane;
- collecting condensed liquid from the inner surface of said membrane;
- and radiating heat under isothermal conditions from said membrane surface.
