Abstract
A rodbaffle heat exchanger is disclosed in which a plurality of detuning plates are provided to prevent the formation of standing accoustical waves from forming in the shell-side fluid flow path such that vibration and tube damage is prevented.
Claims13
A rodbaffle heat exchanger having an axial centerline and comprising a plurality of rodbaffle means spaced along the axial, longitudinal length of said heat exchanger and defining a plurality of sections of said heat exchanger therebetween along its axial, longitudinal length, a plurality of tubes supported by said rodbaffle means, and a plurality of separate acoustical detuning plate means, positioned in said plurality of heat exchanger sections for preventing damage to said heat exchanger from the formation of acoustical stading waves is said heat exchanger, and wherein said plurality of separate acoustical detuning plate means are alternately positioned to extend along different chords of said heat exchanger in different heat exchanger sections thereof.
A rodbaffle heat exchanger comprising a plurality of rodbaffle means spaced along the axial, longitudinal length of said heat exchanger and defining a plurality of sections of said heat exchanger therebetween along its axial, longitudinal length, a plurality of tubes supported by said rodbaffle means, and a plurality of separate acoustical detuning plate means positioned in said plurality of heat exchanger sections for preventing damage to said heat exchanger form the formation of acoustical standing waves in said heat exchanger wherein a pair of said plurality of separate acoustical detuning plates means are positioned in each heat exchanger section of said heat exchanger where standing acoustical waves would otherwise occur, said plurality of separate acoustical detuning plates means extending along said axial, longitudinal length of said heat exchanger and one of said pair of said plurality of separate acoustical detuning plate means extends in a different direction than that of the other of said pair in each heat exchanger section.
A heat exchanger having tube means for the passage of a first fluid within said tube means, and a shell side comprising the spaces between said tube means within a surrounding shell,
- a plurality of acoustical detuning plate means individually located and extending through different portions of said heat exchanger, and
- each of said plurality of acoustical detuning plate means having a plurality of passage means extending therethrough for permitting the flow of shell-side fluid through said plurality of acoustical detuning plate means.
A rodbaffle heat exchanger comprising a plurality of rodbaffle means spaced along the axial, longitudinal length of said heat exchanger and defining a plurality of sections of said heat exchanger therebetween along its axial, longitudinal length, a plurality of tubes supported by said rodbaffle means, and a plurality of separate acoustical detuning plate means positioned in said plurality of heat exchanger sections extending along said axial, longitudinal length for preventing damage to said heat exchanger from the formation of acoustical standing waves in said heat exchanger wherein said heat exchanger has a substantially circular cross-section and said plurality of separate acoustical detuning plate means alternately extend along different chords of said substantially circular cross-section of said heat exchanger in different heat exchanger sections thereof.
