HEAT TRANSFER PLATE AND GASKET Russian patent published in 2021 - IPC F28D9/00 F28F3/08 

FIELD: heat engineering.

SUBSTANCE: invention relates to heat engineering and can be used in plate heat exchangers. A heat transfer plate (2) and a gasket (5) are proposed. The heat transfer plate (2) contains at least one first region (44) of the opening and opposite front and rear sides (4, 6), the first and second planes (38, 40), limiting the length of the heat transfer plate (2). Each of said at least one first opening region (44) further comprises an annular first inner portion (56) of the opening extending along the first and second sections (52, 54) of said first inner edge (50), wherein the first inner portion (56) the hole contains support protrusions (62) with an upper section (64) extending in the first plane (38), and the heat transfer plate (2) extends within the first inner section (56) of the hole and outside the said number of first support protrusions (62 ) at some distance ≠ 0 from the first and second planes (38, 40).

EFFECT: invention prevents the formation of unfilled gaps between corrugated or wavy inner edges of heat transfer plates.
