| 摘要 |
The invention relates to a plate heat exchanger that includes a plurality of first and second heat exchanger plates provided beside each other for forming a plate package having a surrounding edge side and first plate interspaces for a first medium and second plate interspaces for a second medium. A first heat exchanger plate forms, together with a second heat exchanger plate, a pair of heat exchanger plates which encloses a first plate interspace. The plate package has a plurality of such pairs. Each heat exchanger plate has two portholes which form ports extending through the plate package and communicating with the first plate interspaces. The second plate interspaces are open through the enclosing edge side. Each first heat exchanger plate includes a first bent part that cooperates with a bent part 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 first heat exchanger plate cooperates with a corresponding porthole of a second heat exchanger plate in order to ensure that each pair takes a determined position in relation to adjoining pairs. |
