MATRIX OF PLATE HEAT EXCHANGER Russian patent published in 2010 - IPC F28D9/00 F28F3/00 

FIELD: heating.

SUBSTANCE: matrix of plate heat exchanger consists of set of plates with corrugations arranged at the sharp or blunt angle to any side of plates and forming heat exchanging surface. Heat exchanging surface covers the whole plate, frontal surfaces of coolants inlet and outlet are arranged along periphery of plate. As plates are superimposed one onto another, crossing channels are arranged for heating and heated coolant. Channels are tightly closed along perimetre of plates, apart from channels of according coolant at the sections of inlet and outlet. Sections of inlet and outlet of one coolant are located at opposite sides of plates, and of the other outlet - symmetrically at two other sides as sections of inlet are located at the distance from the sections of outlet by length of plate without flanges. Channels for heating and heated coolant along perimetre of plates are closed tightly by connected flanges of external edges and additional "П"-shaped flanges.

EFFECT: invention makes it possible to increase efficiency of heat exchanger, to reduce weight and to simplify technology of manufacturing.
