Comparison for Heat Transfer Performance of Diesel Engine Radiator

Experimental value and theoretical value of heat transfer parameter of the heat transfer have been acquired by experiments and calculation.An experiment has been made among three diesel engines,that is,a flat plate-finned tube radiator,a helical round-finned tube radiator and an integral comb-finned tube radiator to compare their heat transfer factors under one operating mode.Compared with theoretical value,experimental value of heat transfer parameter of 2 heat transfers is smaller,and the experimental value has been acquired by quadric fitting calculation of by-sending factor experiment made between the aflat plate-finned tube radiator and the ntegral comb-finned tube radiator.
