SHELL AND TUBE TYPE HEAT EXCHANGER

摘要

This invention relates to a heat exchanger in which a medium flowing from a distribution header to a collection header is fed to the tube bundle through a plurality of pipes and subheaders and then gathered from the tube bundle into the collection header through a second plurality of subheaders and pipes. The subheaders are thin-walled, flexible, box-like members that can accommodate the expansions and contractions of the tubes in the tube bundle.
