Kettle Reboiler - an overview | ScienceDirect Topics
Helical-coil heat exchanger Although double-pipe heat exchangers are the simplest to design, the better choice in the following cases would be the helical-coil heat exchanger (HCHE). The main advantage of the HCHE, like that for the SHE, is its highly efficient use of space, especially when its limited and not enough straight pipes can be laid.
