Patent number: 10508869Abstract: A method and a control unit for evaluating lifting force of a gas phase of a substantially vertical upward two-phase flow of a first fluid in a heat exchanger. The first fluid comprises the gas phase and a liquid phase. The method comprises determining that the lifting force of the gas phase is insufficient for lifting the liquid phase based on hot end approach of the heat exchanger and/or on pressure drop of the first fluid over the heat exchanger. The control unit is configured to determine that the lifting force of the gas phase is insufficient for lifting the liquid phase based on hot end approach of the heat exchanger and/or on pressure drop of the first fluid over the heat exchanger. A heat exchanger assembly comprising a heat exchanger and the control unit.Type: GrantFiled: August 23, 2017Date of Patent: December 17, 2019Assignees: ALFA LAVAL CORPORATE AB, ALFA LAVAL PACKINOXInventor: Laure Guichard

Patent number: 9140498Abstract: A method is provided for manufacturing a bundle of plates for a heat exchanger made up of a stack of plates. The method includes reducing by machining the initial thickness of each plate by making at least at the periphery of the plate, at least one connecting shoe having a height greater than the thickness of the machined plate, forming on the central portion of the plate, corrugations, to be superposed pairwise on the plates, connecting the shoes in contact with the plates of each pair through a weld bead, superposing the pairs of plates and connecting the shoes in contact with the pairs of plates through a sealed weld bead by arranging a superposition of open or closed ends for alternate inflow or outflow of said fluid.Type: GrantFiled: May 17, 2010Date of Patent: September 22, 2015Assignees: ALFA LAVAL VICARB, ALFA LAVAL PACKINOX, Commissariat a l'energie atomique et aux energies alternatives, AREVA NPInventors: Gilles Francois, Gabriel Merle, Patrice Tochon, Franck Pra, Claude Roussel, Olivier Noel Baron, Pierre-Xavier Bussonnet, Alain Bourgeon

Publication number: 20070169924Abstract: The invention relates to an installation for exchanging heat between fluids, the installation being of the type comprising a leaktight enclosure, means for exchanging heat between the fluids, and fluid admission and discharge means. The heat exchanger means comprise bundles of plates formed by stacks of horizontal plates and distributed in a star configuration around a tubular central collector concentric with the enclosure. Each bundle of plates has a front vertical wall secured to the collector and a rear vertical wall that is free, and each is slidably supported on a support member secured to the enclosure.Type: ApplicationFiled: January 17, 2007Publication date: July 26, 2007Applicant: Alfa Laval PackinoxInventor: Pierre-Xavier Bussonnet
