<p>A plate heat exchanger comprises a plurality of first and second heat exc hanger plates (1, 2) provided beside each other for forming a plate package (3) having a surrounding edge side and first plate interspaces for a first m edium and second plate interspaces for a second medium. A first heat exchang er plate (1) forms together with a second heat exchanger plate (2) a pair of heat exchanger plates, which encloses a first plate interspace. The plate p ackage comprises a plurality of such pairs. Each heat exchanger plate has tw o portholes which form ports extending through the plate package and communi cating with the first plate interspaces. The second plate interspaces are op en through the enclosing edge side. Each first heat exchanger plate comprise s a first bent part (21) which cooperates with a bent part (22) of a second heat exchanger plate in order to ensure that these two heat exchanger plates take a determined position in relation to each other. Each porthole of a fi rst heat exchanger plate cooperates with a corresponding porthole of a secon d heat exchanger plate in order to ensure that each pair takes a determined position in relation to adjoining pairs.</p> |
