Shell with integral internal passage and method of making same

摘要

A formed non-planar heat exchanger having two non-planar plates continuously joined across their contacting surfaces and complementarily curved to form an integral curved member; at least one channel is formed in at least one of the plates to define an integral internal heat exchange fluid flow passage within the curve contour of the curved member; the integral internal heat exchange fluid flow passage conforms with the curved member. A method of making such a device is also disclosed.
