DEFINITION

Classification: 165/272

Control of heat pipe heat transfer characteristics:

(under subclass 200) Subject matter wherein said heat transfer apparatus comprises a substantially sealed cavity containing a liquid, heat being absorbed in one portion of said cavity by vaporization of the liquid and released in a second portion of said cavity by condensation of the vapor, the condensed vapor being recycled for subsequent evaporization; and further including means to control the vaporization, condensation or recycling.
