Abstract: 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.

Abstract: A plate heat exchanger comprises a plurality of heat exchanger plates provided beside each other to form a plate package with first plate interspaces for a first medium and second plate interspaces for a second medium. The first and second plate interspaces are provided in an alternating order in the plate package. A number of portholes extend through the plate package and form first inlet and outlet channels arranged to convey the first medium into and out from the first plate interspaces. An insert element is provided in one of the portholes for the first medium. The insert element comprises an annular body, an annular flange, projecting from the annular body and provided between two of the heat exchanger plates in the plate package.
