Abstract
A shell and tube heat exchanger is disclosed in which the distribution of the fluid on the shell is substantially improved by the positioning of flow-restrictive disks on the tubes near the inlet and outlet regions of the exchanger. Positioning of the disks in other regions of the exchanger is also disclosed in order to create turbulence and increased beat transfer.
