ABSTRACT:
A heat exchanger having two or more tube bundles extending parallel to the shell with a central longitudinal space between the tube bundles. The tube bundles have a longitudinal axis is symmetry in such space. The tubes in each bundle are laid out in concentric arcs. The arcs of each bundle have a common center of curvature which is displaced from the axis of symmetry and also from the center of curvature of each other tube bundle. The corners between the tube bundles may contain fill-in tubes. This allows compact tube packing while preserving relatively uniform fluid velocities.
