Title: Multi-zone shell and tube heat exchanger

Abstract

A shell and tube heat exchanger has elongated shell having first and second opposing ends and an open interior. A core divides the open interior of the shell into first and second enclosed portions. The shell has first and second tube fluid openings at opposing ends. End plates divide the first and second enclosed portions into manifold portions and enclosed shell chamber portions. Tubes extend from the end plates, through the enclosed shell chambers to the core. Shell fluid openings are at sides of the elongated shell, a first fluid opening communicating with the first shell chamber, and a second fluid opening communicating with the second shell chamber. The shell has a long axis, and the end plates are angled relative to the long axis. The tubes are polygonal with rounded corners and straight sides. The heat exchanger can be used for both evaporation and condensation processes.
