Abstract

The invention discloses a cooling system for a converter of a diesel locomotive and belongs to the field of cooling systems for converters. An independent air inlet unit is arranged on the top of a radiator; the radiator is arranged on the top of an independent air chamber; a traction motor ventilator is arranged in the independent air chamber; the air inlet of a main generator is communicated with the independent air chamber; the independent air chamber is communicated with the independent air inlet unit; a water outlet pipeline of the radiator is connected with the water inlet of a water pump; the water outlet of the water pump is connected with a converter water inlet pipeline; the converter water inlet pipeline is connected with the water inlet of the converter; the water outlet of the converter is connected with a converter water outlet pipeline; the converter water outlet pipeline is connected with the water inlet of the radiator; and the water outlet of the radiator is connected with a radiator water outlet pipeline. The weight of the whole cooling system for the converter is reduced, so the space in the diesel locomotive is saved, the auxiliary power consumption is reduced, the reliability of the system is improved and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to a cooling system for a converter of a diesel locomotive, and belongs to the technical field of converter cooling. Background technique [0002] At present, the domestic diesel locomotive converter water cooling method adopts the cooling tower structure. The cooling tower structure includes components such as radiator, cooling fan, motor, wind chamber and electric control, and its whole structure is heavy in weight and large in volume, so it is very difficult to arrange on a locomotive with less space and takes up space. In addition, the working condition of the converter changes frequently and is complicated, which makes the control of the cooling fan more complicated, and more components also reduce the reliability of the system. The power consumption of the cooling fan is about 28kW, which increases the fuel consumption and exhaust emission of the diesel engine. Contents of the invention [0003] The object of the present...
