摘要

Improvements in the construction of tubular heat exchangers, of the type having a liquid inlet box, a tube sheet that forms a wall of the box, a plurality of tubes opened in the box through the tube sheet and joined the same coming out of said sheet in opposite direction to the box, the box having a separate inlet or intake mouth of the tube sheet; characterized in that each changer is provided with a new combination of means for inhibiting the deterioration of the tube sheet and the tubes, and of the joints between them, comprising a deflector separate from the tube sheet, parallel thereto., and interposed between said tube sheet and said inlet or intake mouth, said baffle having a plurality of holes passing through it, one of said holes being prevented by each tube opened in the tube sheet and aligning coaxially therewith, and a second separate parallel deflector, interposed between the first deflector and the intake mouth and having holes that pass through it in coaxial alignment with the holes of the first deflector, each orifice having a cross-sectional area smaller than the internal cross-sectional area of the aligned tube with the same.
