Abstract
The present invention relates broadly to methods for heating or cooling a media in a indirect heat exchanger. In a specific embodiment of the invention, the indirect heat exchanger is a shell and tube heat exchanger where the tube is coiled within the shell and the coiled tube includes baffles at least every third coil. The media is passed through the coiled tube and a coolant or heat source flows through the surrounding shell such that the coolant or heat source floods the entire shell. The baffles redirect the coolant or the heat source in such a way as to cause turbulent flow. This turbulent flow allows the heat transfer process to be conducted in a uniform and highly efficient manner.
