FIELD: power engineering.
SUBSTANCE: invention relates to the field of heat engineering and may be used in heat exchangers. A rotor regenerative heat exchanger comprises heat transfer elements comprising V-shaped grooves, which provide for the distance between adjacent elements, and combs (corrugations), arranged between V-shaped grooves. Corrugations have different height and/or width.
EFFECT: improved heat transfer by increased air turbulence or furnace gas between elements.
