MULTITUBE TYPE HEAT EXCHANGER

摘要

PURPOSE:To prevent generation of a columnar resonance sound in a mode of the flowing direction of an extra-tube fluid due to a Karman vortex generated in the rear stream of a heat exchanger tube. CONSTITUTION:Between tube groups 1 disposed with a space set therebetween in the flowing direction of an extra-tube fluid, a wire mesh 4 is disposed so that it transverses the flow of the extra-tube fluid. Resistance is given to the vibration of fluid particles in the flowing direction of the extra-tube fluid by the wire mesh 4 and thereby generation of a resonance sound in a mode of the flowing direction is prevented.
