ABSTRACT:
Rod type supports or baffles are disclosed for arrays of tubes, especially those arranged in the form of a tube bundle. Each baffle comprises a pair of arcuate surfaces with a plurality of rods extending therebetween and each rod being non-normally disposed with respect to the axis of a tube bundle. In a preferred embodiment, a plurality of baffles are employed in a tube bundle so as to cause shell side fluid to sweep across the tubes in a spiral pattern, such as a double helical pattern. The invention provides an improvement in the mixing of shell side fluid in a rod baffle heat exchanger.
