Abstract: The invention refers to a plate package for a plate heat exchanger, a method for manufacturing a plate package, a use of a plate package, and a plate heat exchanger. The plate package includes a plurality of heat exchanger plates (1), which are stacked on each other and which each includes a number of portholes. The plates (1) are compression molded and permanently connected to each other in a number of joints in such a manner that the plates between each other form a first passage for a first fluid and a second passage for a second fluid. The plate package is designed to permit at least one of the fluids to flow through the respective passages at a predetermined maximum working pressure. The plate package has an increased strength achieved by subjecting at least one of the passages to at least a local inner plastic deformation of the plate package.

Abstract: The invention relates to a plate heat exchanger and a method for manufacturing a plate heat exchanger. The plate heat exchanger includes a number of heat exchanger plates (1), which are substantially parallel to an extension plane and arranged adjacent to each other in a plate package (2). A first end plate (8) and a second end plate (9) are arranged on a respective side of the plate package. A first tie sheet (10) and a second tie sheet are arranged on a respective side of the plate package substantially perpendicular to the extension plane. At least one connection member (17) extends between the tie sheets outside one of the end plates (9) and at least one beam (16) extends outside the second end plate (8) in parallel to an extension plane in engagement with the attachment of each tie sheet (10).
