On efficient tubular heat exchangers

The estimates of the heat and mass-dimensional characteristics of a shell-and-tube heat exchanger with a tightly packed tube bundle without baffles in the intertubular space with the intensification of heat exchange via deep profiling have been obtained from the experimental data. A comparison of these data with similar data for a heat exchanger with the intensification of the heat exchange via knurling indicates the obvious advantage of heat exchangers intensified by deep profiling.
