PLATE HEAT EXCHANGER, HEAT EXCHANGE PLATE AND METHOD FOR PROCESSING SUPPLY SUBSTANCE, SUCH AS SEA WATER Russian patent published in 2021 - IPC F28D9/00 F28F3/04 

FIELD: heat engineering.

SUBSTANCE: invention relates to the field of heat engineering and can be used in plate heat exchangers for processing the supplied substance. The plate heat exchanger includes a plate pack containing a plurality of heat transfer plates and defines a heating volume, a cooling volume, and a plurality of process volumes. Each of the process volumes includes an evaporation section for evaporating a portion of the feed, a separation section for separating the non-evaporated portion of the feed from the evaporated portion of the feed, and a condensing section for condensing the evaporated portion of the feed. Each heat exchange plate defines the first thermal interface between the heating volume and the evaporating section of the first process volume, the second thermal interface between the cooling volume and the condensation section of the second process volume, and at least one additional thermal interface between the evaporating section and the condensation section of two adjacent process volumes.

EFFECT: creation of a plate heat exchanger for desalination that does not need a container.
