CROSSWISE BAFFLE FOR SPACING APART OF TUBE SHELL TUBES Russian patent published in 2016 - IPC F28F9/00 

FIELD: heating.

SUBSTANCE: claimed baffle comprises top and bottom plates 1 and 2, cylindrical sleeves 3 and a peripheral ring 4. Every plate 1 and 2 has slots and ledges 6 alternating on one side of the plate. The slots and ledges 6 of the top plates 1 are located at the bottom side of the plate 1 while the slots or ledges 6 of the bottom plate 2 are arranged at their top sides. The wall of every sleeve 3 has two lengthwise diametrically opposite cut-outs from both ends of the sleeve 3. The diameter of location of the top end cut-outs in the sleeve 3 is perpendicular to that of the bottom end cut-outs. The top plates 1 are fitted in the sleeve top end cut-outs while the bottom plates 2 are fitted in the sleeve bottom ends cut-outs. The slots of the plates 1 and 2 are arranged inside the sleeve 3 while the bottom plates 2 are located perpendicular to the top plates 1. Note here that this configuration allows the space between every four adjacent sleeves 3 to house the tube shell tubes with the mounting clearances between the said tubes and the said four adjacent sleeves 3. The ring 4 has round bores made at its inner surface to receive the sleeves 3 arranged along the edges of the said tube shell. The said ring 4 has holes 12 for the ring attachment in the tube shell housing by coupling screws and spacer tubes.

EFFECT: ruled out deterioration of heat exchange conditions, reliable securing of tubes, uniform fluid flows in the intertubular space.
