U-tube heat exchanger

U-tube heat exchanger

[′yü ¦tüb ′hēt iks‚chān·jər]
(chemical engineering)
A heat-exchanger system consisting of a bundle of U tubes (hairpin tubes) surrounded by a shell (outer vessel); one fluid flows through the tubes, and the other fluid flows through the shell, around the tubes.
