Experimental  and calculated dependences of the coefficient 
of thermal efficiency of a heat exchanger are presented for 
various effective diameters of the internal channels. It is 
shown that a region  of  a local maximum of the coefficient 
of thermal efficiency exists  in  the regime of a turbulent 
flow of the coolant.
