摘要： The present invention relates to a plate heat exchanger for treatment of a feed. The plate heat exchanger includes a plate package comprising a plurality of heat exchanging plates and defining a heating volume, a cooling volume and a plurality of process volumes. Each of the process volumes includes an evaporation section for evaporation of a part of the feed, a separation section for separating a non-evaporated part from an evaporated part of the feed, and a condensation section being arranged to condense the evaporated part of the feed. Each heat exchanging plate defines a first thermal interface between the heating volume and the evaporation section of a first process volume, a second thermal interface between the cooling volume and the condensation section of a second process volume, and at least one further thermal interface between an evaporation section and a condensation section of two adjacent process volumes.

摘要： A plate heat exchanger (2) comprising a first frame plate (4), a second frame plate (6) and a stack (24) of heat transfer plates (26) is provided. Each of the heat transfer plates has a center portion (56) and a peripheral portion (58) encircling the center portion. The heat transfer plates are arranged in pairs between the first and the second frame plate, a first flow path (F1) for a first fluid being formed between the heat transfer plates of the pairs and a second flow path (F2) for a second fluid being formed between the pairs of heat transfer plates. One of the first and second flow paths is a free-flow path along which the center portions of the heat transfer plates are completely separated from each other. The plate heat exchanger is characterized in further comprising a reinforcement plate (28a) which is thicker than the heat transfer plates and has a center portion (100) encircled by a peripheral portion (102). The reinforcement plate is arranged between the first frame plate and the stack of heat transfer plates. A first number of permanent reinforcement joints (106) each bond together the reinforcement plate and an outermost heat transfer plate (26a).

摘要： A heat transfer plate for a plate heat exchanger comprising a number of ridges (210) and troughs (220) which have been pressed into the plate, the heat transfer portion of the plate having a plurality of juxtaposed rows (200) of said ridges (210) and troughs (220). The rows (200) of ridges (210) and troughs (220) are separated from each other by essentially plane channel portions (240). Each row (200) presents alternating elongated ridges (210) and elongated troughs (220) which extend along a main flow direction (F). The transition between each ridge (210) and an adjacent trough (220) in the same row (200) is formed by a transition portion (230) which is inclined relative to the central plane (P1) of the plate (1). The heat transfer plate is used in a plate pack for a plate heat exchanger.

摘要： The invention refers to a plate package and a plate heat exchanger. The plate package includes plate modules with two heat exchanger plates (3), which extend at at least an intermediate plane, an upper plane and a lower plane. The heat exchanger plates are permanently connected to each other and form an inner first space therebetween. The plate modules are stacked to each other and form a second space therebetween. Each heat exchanger plate includes two portholes (13) which permit communication with the first space. Each porthole is defined by a port edge (31) and surrounded by a ring groove (32) for a gasket member at a distance from the port edge. The ring groove is formed by a bottom (33) at the level of the intermediate plane, an inner lateral limitation (34) extending upwardly from the bottom towards the port edge, and an outer lateral limitation (35) extending upwardly from the bottom away from the port edge. The outer lateral limitation forms a surface extending without any interruptions continuously around the bottom whereas the inner lateral limitation has a discontinuous extension around the bottom and includes interruptions along this extension.
