SHELL-TUBE HEAT EXCHANGER

摘要

PURPOSE: A shell-tube heat exchanger is provided to improve heat exchange performance by employing a bent tube and supplying heat exchange fluid independently to the bent parts instead of using a plurality of separate heat exchange pipes. CONSTITUTION: A shell-tube heat exchanger comprises a shell tube(10), a tube(20), a first fluid recovery unit, and a second fluid recovery unit. The shell tube comprises a tube type side wall, a cover coupled to the open end of the side wall, and first fluid inlet and outlet which are communicated to the side wall. The tube is formed as being bent within the shell tube and has second fluid inlet and outlet. The first fluid recovery unit collects a first fluid offered to the first fluid inlet through the first fluid outlet. The second fluid recovery unit collects the second fluid offered to the second fluid inlet through the second fluid outlet.
