PLATE-TYPE HEAT EXCHANGER Russian patent published in 2017 - IPC F24F12/00 F24F7/00 

FIELD: heating system.

SUBSTANCE: plate-type heat exchanger has the sexangle-shaped parallel salient wafer pack along the perimeter, where the contiguous plates are in contact with each other and form channels. Upon that, every plate has the sexangle-shaped frame and the guides within the frame, where the guides are flat on the plate one side, and the guides are protruding on the plate other side. Two plate frame parallel sides are chamfered accomplished, and two other plate frame parallel sides are accomplished with deepenings, where the chamfered frame sides of one plate are attached to the other plate frame sides with deepenings, and the width of the chamfered frames sides is greater than the width of the frames with deepenings sides. Moreover, the sides of the frame with deepenings are holed made, through which the air enters and (or) exits, passes through the channels.

EFFECT: device design and chamfers in plates presence provide with the flat and laminar airflow followed by the aerodynamic resistance diminution and sound reduction while air streaming through the heat exchanger.
