Abstract
A plate heat exchanger includes heat exchanger plates forming first, second and third plate interspaces. The plates extend between a top plane and a bottom plane. First inlet and outlet ports communicate with the first plate interspaces. Second inlet and outlet ports communicate with the second plate interspaces. Third inlet and outlet ports communicate with the third plate interspaces. A porthole of the second and third ports is surrounded by an outer flat area surrounded by an inner flat area. The outer flat area is located at one of the top and bottom planes. The inner flat areas of the second ports of the plates, enclosing the second plate interspaces, are located at a distance from each other. The inner flat areas of the second ports of the plates, enclosing the third plate interspaces, adjoin each other.
