Abstract
A shell-and-tube heat exchanger with a tube sheet having partition grooves used to form joints with partition plates contained within the exchanger head. The partition plates define chambers within the head of the exchanger which direct the fluid through the exchanger tubes and which allow for the use of an unequal number of tubes per tube-side pass.
