The invention relates to a plate heat exchangerwith at least two cuboidal modules. The two modulesandare cuboidal and are each closed to the outside by cover sheets. The two modulesandare arranged such that in each case, cover sheetsandof the same size are directly adjacent. On the contact surfaces, sectionsare welded that prevent movement of the two modulesperpendicular to the contact surfaceseither alone or with an additional formed part

Plate heat exchanger with several modules connected by sections

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.

Method for producing a plate heat exchanger with multiple heat exchanger blocks connected by solder-coated supports

The invention describes a plate heat exchangercomprising two modulesand. The two modulesandare cuboidal and in each case are closed off to the outside by cover sheets. The two modulesandare arranged such that cover sheetsandof the same size are directly adjacent. The two cover sheetsandform the contact surface between the two modulesandof the plate heat exchanger. The two contact surfacesandare joined to one another via a suitable adhesive.

Plate heat exchanger with several modules connected by sheet-metal strips

The invention relates to a distribution system () for distributing a fluid () into a container () from a fluid inlet () of the container (). Distribution system () comprises one or more guide plates that form a guide section () and a distribution section () that adjoins the guide section (). Distribution section () has regions () with openings () for allowing fluid () to pass through. The invention also relates to a heat exchanger device () that has a container () with a fluid inlet (), with at least one heat exchanger block () that is arranged in the container (). A distribution system () according to the invention is arranged in the container () above the heat exchanger block ().

Distribution system and heat exchanger apparatus

The invention relates to a plate heat exchanger that consists of several pieces of sheet metal that are arranged parallel to one another, that are at least partially corrugated and that form a considerable number of heat-exchange passages. A header creates a flow connection among at least some of the heat-exchange passages. At least two parts () of the plate heat exchanger consist of metallic materials that cannot be welded to one another.
