Method for braze-joining spirally wound tapes to inner walls of heat exchanger tubes

Patent Garrison, Melton E [Powell, TN]

The present invention is directed to a method of fabricating heat exchanger tubes in which twisted tapes are utilized for promoting turbulence and heat transfer. The method of the present invention provides for the brazing of the tapes to the inner walls of the tubes for enhancing heat transfer between the fluid within the conduit and a fluid medium outside of the conduit by conduction through the tape. The braze joint of the present invention is coextensive with the tape over the entire length thereof within the conduit. The practice of the present invention is achieved by placing a fillermore » « less

Superconducting electrical machine with double re-entrant ends for minimizing heat leak

Patent Morrison, Darrell

A superconducting electrical machine includes at least one re-entrant end including at least two segments. The at least two segments are continuous. At least one re-entrant end may be included in a stator of the superconducting electrical machine, the stator being disposed substantially coannular with a longitudinal axis. At least one re-entrant end may also be included in a rotor of the superconducting electrical machine, the rotor being configured to rotate about a longitudinal axis. A first segment is substantially perpendicular to a plane parallel to the longitudinal axis, and a second segment is coannular with the longitudinal axis. Heatmore » « less

Double wall vacuum tubing and method of manufacture

Patent Stahl, Charles R [Scotia, NY]; Gibson, Michael A [Houston, TX]; Knudsen, Christian W [Houston, TX]

An evacuated double wall tubing is shown together with a method for the manufacture of such tubing which includes providing a first pipe of predetermined larger diameter and a second pipe having an O.D. substantially smaller than the I.D. of the first pipe. An evacuation opening is then in the first pipe. The second pipe is inserted inside the first pipe with an annular space therebetween. The pipes are welded together at one end. A stretching tool is secured to the other end of the second pipe after welding. The second pipe is then prestressed mechanically with the stretching toolmore » « less

Fluidized bed heat exchanger utilizing angularly extending heat exchange tubes

Patent Talmud, Fred M [Berkeley Heights, NJ]; Garcia-Mallol, Juan-Antonio [Morristown, NJ]

A fluidized bed heat exchanger in which air is passed through a bed of particulate material containing fuel disposed in a housing. A steam/water natural circulation system is provided and includes a steam drum disposed adjacent the fluidized bed and a series of tubes connected at one end to the steam drum. A portion of the tubes are connected to a water drum and in the path of the air and the gaseous products of combustion exiting from the bed. Another portion of the tubes pass through the bed and extend at an angle to the upper surface of themore » bed. « less
