Abstract: The invention relates to a plate heat exchanger 1 with at least two cuboidal modules 1a, 1b. The two modules 1a and 1b are cuboidal and are each closed to the outside by cover sheets 5. The two modules 1a and 1b are arranged such that in each case, cover sheets 9a and 9b of the same size are directly adjacent. On the contact surfaces, sections 20a, 20b are welded that prevent movement of the two modules 1a, 1b perpendicular to the contact surfaces 9a, 9b either alone or with an additional formed part 50.

Abstract: A method for producing a plate heat exchanger with at least two heat exchanger blocks which are produced separately from one another in a soldering furnace Each heat exchanger block has multiple separating sheets arranged parallel to one another and which form a plurality of beat exchanger passages for fluids involved in a heat exchange process. At least one support provided with solder is heated in order to melt the solder, the support is arranged between opposing outer surfaces of the heat exchanger blocks to be connected which are placed one on top of the other or adjacently, the support(s) thus being fixed between the opposing outer surfaces. After the solder is hardened, a bonded and heat-conductive connection is produced between the heat exchanger blocks. Sheets or wire arrangement can be used as the supports.

Abstract: The invention describes a plate heat exchanger 1 comprising two modules 1a and 1b. The two modules 1a and 1b are cuboidal and in each case are closed off to the outside by cover sheets 5. The two modules 1a and 1b are arranged such that cover sheets 9a and 9b of the same size are directly adjacent. The two cover sheets 9a and 9b form the contact surface between the two modules 1a and 1b of the plate heat exchanger 1. The two contact surfaces 9a and 9b are joined to one another via a suitable adhesive.
