Based on thermodynamic experiment data of several typical locomotives, this paper presents the cooling capability of the cooling systems under different circumstance temperatures and locomotive powers ,in order to resolve the main question existing in the cooling system of locomotive at present. Then the reasons that cause the difference between the design parameters and its experiment values of the cooling systems has been analyzed, and the main problem in the locomotive cooling systems is found. At the same time, through comparing some kind of cooling systems used in locomotives, it shows that the double channel cooling system has great importance for the desing of large power locomotive cooling systems. In the end of this paper, some suggestions of improving the locomotive cooling system have been given.
