Abstract: Abstract:The operation situation of the indirect aircooling system was introduced. The working principle of the aircooling radiator and the main reasons of freeze damage of the radiators were analyzed. The method and target of reformation were proposed. The circulating water input and output ways of the cooler of the indirect aircooling system were changed. The connection mode of the air emptying pipes of the cooling column waterfeeding chamber and the microcirculation system of air loop pipes were improved. The performance test result of improved system shows that the winter freezeproofing performance and the annual economic efficiency of the system were improved significantly.
