PLATE HEAT EXCHANGER WITH IMPROVED STRENGTH IN PORT AREA

摘要

A plate heat exchanger comprises plural heat exchanger plates and at least one adapter plate, which each extend parallel with a main extension plane. The heat exchanger plates form a plate package with first and second plate interspaces for first and second mediums. Each heat exchanger plate has four port holes extending through the plate package. The heat exchanger plates comprise outermost heat exchanger plates. Two of the plate interspaces form a respective outermost plate interspace at a respective side of the plate package, which are delimited outwardly by a respective one of the outermost heat exchanger plates, and the adapter plate is outside one of the outermost heat exchanger plates. A distance plate between the adapter plate and one of the outermost heat exchanger plates has at least two port holes concentric with each of the respective port holes of the outermost heat exchanger plates and the adapter plate.
