ABSTRACT:
An improved heat exchange construction for tube bundle heat exchange systems including shell (4) and tube (6) types (2), incorporating detached, essentially spherical flow interrupters (24, 26) arranged in an interconnected matrix configuration (22), and disposed within the tube bundle interstices (9, 11). Substantial improvements in heat exchange and exchanger tube life, is provided. The mechanically interconnected matrix configuration of the flow interrupters provides an economical and easily assembled means to improve heat transfer outside of individual tubes in a tube bundle configuration. Continuous tube support is also provided by tube/interrupter contact, thereby greatly decreasing fatigue failures encountered in presently used multiple tube, tube/shell heat exchanger configurations (2).
