MUMBAI, India, June 26 -- Intellectual Property India has published a patent application (202617068714 A) filed by Lummus Technology LLC on June 01, 2026, for Heat Exchanger With Helical Baffles.
Inventors include Groppi, Roberto; Elsayed, Sherif; Jibb, Richard; and Podrebarac, Gary.
The application for the patent was published on June 19, 2026, under issue no. 25/2026.
Abstract: A heat exchanger includes a shell with a longitudinal axis and helical baffles inside the shell and arranged along the longitudinal axis in an alternating pattern of a first baffle followed by a second baffle of the helical baffles. Each helical baffle includes first holes and second holes that receive tubes. The second holes have a diameter larger than the first holes or there is a clearance between the second holes and the tubes that is greater than a clearance between the first holes and the tubes to intentionally induce an increase in a leakage stream in the spaces between the second holes and the tubes. Such increase in the leakage stream maintains a relatively constant rate of heat transfer while reducing pressure drop, thereby resulting in an improved heat transfer to pressure drop ratio for the heat exchanger.
