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.

  • Patent number: 6802365
    Abstract: Plates of a heat exchanger plate pack are formed by a stack of plates defining at least two independent fluid flow circuits, each circuit comprising a central heater part and a border with a smooth surface. A cutout is produced on corners of each plate and on the border to be connected, of each plate to the adjacent plate, a fold is made in order to form a first flange. On this first flange a fold is made in order to form a second flange laying parallel to the central part of the corresponding plate and directed outward from the plate. The plates are superposed and held by applying the second flange of each plate to the second flange of the adjacent plate. A continuous sealed weld bead is made by completely melting the second superposed flanges of adjacent plates.
