Abstract

The invention relates to a spraying and atomizing cooling system for an internal combustion locomotive, which comprises an upper water tank, a radiator and a lower water tank. The radiator is arranged between the upper and lower water tanks. A fan is arranged on one side of the radiator. A nozzle is arranged on the other side of the radiator. The nozzle is connected with a water storage tank through a stop valve and a second water pump. A water outlet of the second water pump is connected with the water storage tank through a bypass valve to form a bypass circuit. According to the invention, the nozzle, the water pump, the stop valve and the water storage tank are provided additionally under the conditions of working state, working space and system operation of the existing device so that the cooling capacity of the cooling system of the internal combustion locomotive is increased by about 20%-30% compared with that of the existing cooling systems. The spraying and atomizing cooling system for the internal combustion locomotive can meet the demand of actual operation so as to ensure the safety and reliability of the locomotive in the operation process.

Description

technical field [0001] The invention relates to a spraying and atomizing cooling system, in particular to a spraying and atomizing cooling system for cooling a diesel locomotive. Background technique [0002] The cooling system of diesel locomotive has a direct relationship with the normal operation of the train. When the heat dissipation capacity of the internal combustion engine cooling system is insufficient, especially in some special environments, such as when the train climbs a slope or enters a tunnel, the water temperature rises sharply, especially in some cities in the south where the summer is relatively hot, the temperature even exceeds the warning temperature, which seriously affects the train. running. In recent years, there have been dozens of failures due to the high water temperature of the locomotive, which caused the unloading of the locomotive in the traction state, the slow running of the train, or the inability of the diesel locomotive to continue t...
