Tube heat exchanger key Features:
Shell: The large outer vessel that contains one fluid (the "shell-side fluid").
U-Tubes: A bundle of tubes bent into a U-shape. A second fluid (the "tube-side fluid") flows through these.
Tube Sheet: A single, thick metal plate drilled with a precise pattern of holes. Both the inlet and outlet legs of the U-tubes are attached to this same tube sheet.
Stationary Channel/Head: The chamber at the front where the tube-side fluid enters and exits. It contains a crucial part called the bonnet or head, which is split by a partition (baffle). This partition directs the incoming fluid into the tubes and keeps it separate from the outgoing fluid.
Baffles: Plates placed inside the shell. They serve two main purposes:
They support the long, U-shaped tubes to prevent vibration.
They force the shell-side fluid to flow back and forth across the tube bundle, increasing heat transfer efficiency.
Type of Heat exchanger tube:
U-bend & Straight.
