Moving-Gradient Furnace With Constant-Temperature Cold ZoneOuter heat pipe helps in controlling temperature of cold zone of furnace. Part of heat-pipe furnace that includes cold zone surrounded by another heat pipe equipped with heater at one end and water cooling coil at other end. Temperature of heat pipe maintained at desired constant value by controlling water cooling. Serves as constant-temperature heat source or heat sink, as needed, for gradient of temperature as gradient region moved along furnace. Proposed moving-gradient heat-pipe furnace used in terrestrial or spaceborne experiments on directional solidification in growth of crystals.
