<p>A plate condenser comprising a plurality of heat exchanging plates (31) arranged in a pack. Vapour to be condensed enters the plates (31) along the longitudinal edges (32,33) and the upper transversal edge (34). A cooling medium is passed in a cross-flow between in inlet port (36) and an outlet port (37). The condensed vapour is collected below the bottom transversal edge (35) in a tray (53). The plates (31) are provided with a skewed surface pattern in the central area in order to form guide members (41, 42) and another pattern at the top and bottom ends. The patterns separate and support the plates (31). A channel (44) provided with several small openings (45) extends in the longitudinal direction along the centre of the plate (31). The condensed water flows at the outside of the channel (44) to outlet openings (49, 50) and possible inert gases and non-condensed vapour enters the interior of the channel (44) and are exited.</p> |
