PLATE OF HEAT EXCHANGER AND PLATE HEAT EXCHANGER CONTAINING SUCH PLATE OF HEAT EXCHANGER Russian patent published in 2017 - IPC F28F3/08 

FIELD: heating.

SUBSTANCE: plate of a heat exchanger has hole (36, 38, 42, 44) of an opening with basic point (80), which coincides with central point (C) of the highest imaginary circle (82), which can be inscribed into the opening hole. Hole of the opening is located in the left half and the right halves of the heat transfer plate and has the shape determined by multiple angular points (66, 68, 70) of an imaginary flat geometric figure (72), at least one of which is displaced from arc (92) of a circle, and by the same multiple fully curved lines (74, 76, 78) connecting the angular points. First angular point (66) of the angular points is located closest to transition (84) between the first short side and the first long side of the heat transfer plate and at first distance (d1) from the basic point. Second angular point (68) of the angular points is located closest to the first angular point in the clockwise direction and at second distance (d2) from the basic point. Third angular point (70) of the angular points is located closest to the first angular point in the counterclockwise direction and at third distance (d3) from the basic point.

EFFECT: proposed are plate (4, 6, 8) of a heat exchanger and plate heat exchanger (2) containing such plate of a heat exchanger.
