DEVICE FOR AIR COOLING OF GAS Russian patent published in 2006 - IPC F24F3/14

Abstract RU 2283989 C2

FIELD: power engineering.

SUBSTANCE: device comprises multi-row bank of finned pipes with various coefficient of finning. The finning coefficient of at least two first adjacent pipe rows in the direction of the flow is less than that of at least several pipe rows downstream of the first rows. A part of the pipes of the bank or at least one row of the bank has varying coefficient of finning along the pipe.

EFFECT: enhanced efficiency of heat exchange and reliability.

17 cl, 1 dwg
