CORRUGATED RIBS FOR HEAT EXCHANGER Russian patent published in 2019 - IPC F28F1/30 F28F1/32 F28F13/12 

FIELD: heating equipment.

SUBSTANCE: corrugated ribs having high heat exchanger performance characteristics and not causing clogging even in a gaseous environment with the presence of solid impurities such as dust are disclosed. Each wall surface 3 of corrugated ribs comprises alternate parallel projections 4 and grooves 5 with inclination angle of 10–60°. When determining Wh as height of projections and grooves, Wp as pitch of ledges and grooves, Pf as pitch of corrugated ribs and Tf as thickness of ribs, the following conditions are met: Wh≤0.3674∙Wp+1.893∙Tf-0.1584 [Formula 1], 0.088<(Wh-Tf)/Pf<0.342 [Formula 2], a∙Wp²+b∙Wp+c<Wh [Formula 3], where a=0.004⋅Pf²-0.0696⋅Pf+0.3642, b=-0.0036⋅Pf²+0.0625⋅Pf-0.5752 and c=0.0007⋅Pf²+0.1041⋅Pf+0.2333.

EFFECT: corrugated ribs for heat exchanger are proposed.
