The invention relates to a plate heat exchanger consisting of a plate stack (2) and a housing (1) surrounding the plate stack, wherein the plates (2a) in the plate stack (2) are connected to each other in such a manner that alternatingly a first and at least one further medium can flow through adjacent intermediate plate spaces and that the one medium can be fed to the plate stack (2) via flow-through channels extending in the stack direction or can be discharged from said plate stack, while the other medium can be fed to the intermediate plate spaces associated with said medium via an intermediate space between the housing (1) and the plate stack (2) on the outer circumference or discharged from said intermediate plate spaces. It is essential that the following material combination is present: the plates (2a) of the plate stack (2) consist in the manner known per se of a corrosion-resistant material, whereas the housing (1) consists of a non-corrosion-resistant material, the inner side of which, to which the medium is applied, has an enamel. |
