Heating device
First Claim
1. A heating device comprising a housing formed as a round tube made of heat insulating material, the tube having an inner peripheral surface and first and second ends, a plurality of heat pipes, each being a hermetrically sealed tube with a first evaporation end, a second condensation end, and capillary material on the inner peripheral surface, said heat pipes situated around and adjacent said housing inner peripheral surface and positioned in parallel with each other and with said housing tube axis, said heat pipes positioned with their first and second ends respectively adjacent said first and second ends of said housing, and at each end of the housing an annular end plate of heat insulating material, secured to and maintaining in relative position said heat pipes and housing tube ends, with a cylindrical heating chamber defined by the space radially inward of said heat pipes.
