UDC 536.25:62-405.8

The authors give results of measuring the hydraulic 
resistance, heat transfer, and temperature fields at the numbers Re = 70-3*104 
and Pr = 5.5-8 for cooling systems with rectangular channels with different kinds 
of discontinuity of their walls involving additional channels that act as intensifiers 
of heat transfer. The regions of Re numbers in which this intensification 
is energy-profitable are revealed.
