Bundle with the buffer tube bundle CAVITIES GAZOMASLYANOGO EXCHANGER

摘要

The invention relates to mechanical engineering, namely to Embodiment elements shell and tube exchangers, may be employed in the construction of shell and tube, e.g., gazomaslyanyh heat exchanger for heating fuel gas, cooling oil gas compressor units.; The tube bundle with buffer cavities tube bundle gazomaslyanogo heat exchanger consists of two pipes, coaxially inserted one into another tightly without a gap, the outer wall of the inner tube is provided with parallel longitudinal ribs arranged uniformly over its surface, the cross section of which has the shape of a symmetrical trapezium with equal lateral sides, minimal upper base which tightly without a gap against the inner wall of the outer tube of the tube bundle, providing intimate contact of the metal, when it sides adjacent longitudinal edges form parallel buffer cavity between coaxial tubes of the tube bundle, and the cross section buffer formed cavities has the shape of an isosceles triangle. Buffering naturally formed cavity filled with air.
