PLATE-TYPE HEAT EXCHANGER Russian patent published in 2019 - IPC F28D9/00 

FIELD: heating equipment.

SUBSTANCE: invention relates to heat engineering and can be used in steam and gas turbines, as well as in aircraft gas turbine engines and power plants. In a plate heat exchanger comprising a heat exchanger matrix, each matrix element comprises two halves, which are connected peripherally by a welded or soldered seam, wherein each half has windows for inlet and outlet of one of heat carriers and channels for passage of said heat carrier from inlet opening to outlet, and layers of heat exchanger matrix are connected to each other by welded or soldered seams along the contours of inlet and outlet openings respectively, elements of the heat exchanger matrix are laid in layers so that channels of the first heat carrier form an axisymmetric vortex matrix for the second heat carrier.

EFFECT: improving manufacturability of elements of heat exchanger matrix.
