Shell and tube heat exchanger.

摘要

The heat exchanger of the shell-and-tube type includes end assemblies for venting fluid from the safety gaps of a plurality of multi-walled vented tubes. A telescoping arrangement of fluid flow tubes and inner sleeves associated with the end assemblies provides reliable sealing thereof. Baffling arrangements within the end assemblies and within a heat transfer chamber create an advantageous multi-pass contraflow between the heat exchange fluids.
