DEFINITION

Classification: 165/276

Control of variable thermal conductivity systems (e.g., heat valves, etc.):

(under subclass 200) Subject matter wherein said heat transfer apparatus comprises a gaseous, liquid or solid heat conductive path between a heat source and a heat sink; and further including means to control the thermal conductivity of said path (e.g., by severing the conductive path or by changing its cross-sectional area, electrically charging said path, etc.)
