Abstract
A counterflow heat exchanger comprises coaxial upper and lower tube plates wherebetween extends a tube nest including a plurality of tubes laid parallel to the exchanger axis. The tubes are distributed in a substantially polar symmetry arrangement and have the terminating portion of at least one end thereof substantially perpendicular to the exchanger axis, while the rectilinear portion of the tube nest, which constitutes the heat exchange zone, is enclosed within an annular interspace defined between an inner jacket and an outer shroud.
Claims26
A counterflow heat exchanger having two fixed tube plates, characterized in that it comprises an upper tube plate and a lower plate, said tube plates being coaxial with each other, between said upper and lower tube plates there extending a tube nest including a plurality of tubes laid parallel to the exchanger axis, said tubes of said plurality being connected to said tube plates and substantially distributed in a polar symmetry arrangement and having the terminating portion of at least one end substantially perpendicular to the exchanger axis, the rectilinear portion of said tube nest, substantially constituting the heat exchange zone, being enclosed with substantially uniform distribution within an annular interspace defined between an inner jacket and an outer shroud affixed to said tube plates.
