Plate heat exchanger consisting of a plate stack (2) and a housing (1) surrounding the plate stack, wherein the plates (2a) are connected with one another in the plate stack (2) in such a manner that a first and at least one further medium can flow alternately through adjacent plate interstices, and the one medium can be conducted to and away from the plate stack (2) by way of through-flow channels that run in the stack direction, while the other medium can be conducted to and away from the plate interstices assigned to it by way of an interstice between housing (1) and plate stack (2) on the outer circumference. It is essential, in this connection, that the following combination of materials is present: The plates (2a) of the plate stack (2) consist, in known manner, of corrosion-resistant material, whereas the housing (1) consists of a non-corrosion-resistant material that has an enamel coating on its inner side, which is impacted by medium. |
