A heat exchange module for a locomotive

Abstract

The invention discloses a heat exchange module for a locomotive, which is characterized by comprising an air intake filter, a two-circuit radiator, a fan set, an electric reactor and an air discharge grille which are sequentially arranged along an air flow direction as well as a box structure for containing the components; the air intake filter is arranged on a front end plate of the box structure, and the two-circuit radiator and the electric reactor are respectively fixed on beams in the corresponding positions of the box structure through respective mounting bases by fasteners; an air duct mounting base of the fan set is used for connecting the fan set and the box structure through a vibration absorber; a pipeline is arranged on a water collecting chamber of the two-circuit radiator; and the air discharge grille is arranged on a rear end plate of the box structure. According to the invention, by adopting an overall matching design method, the same heat exchange module is used for simultaneously meeting the requirement of heat dissipation of a traction converter power module and the electric reactor; and the heat exchange module has the advantages of small volume, light weight, compact structure, low noise, convenience in maintenance, low auxiliary power consumption, high reliability, low life cycle cost and the like.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a heat exchange module for a locomotive. Background technique [0002] At present, in the existing cooling technology for traction converters of diesel locomotives, the heat dissipation of the key components of traction converters—the power module and the reactor—is usually equipped with two sets of independent heat exchange devices, which are not compact in structure and occupy a large locomotive space. Heavy overall weight and high total auxiliary power consumption. Therefore, it is necessary to provide a highly integrated heat exchange device to solve the above problems. Contents of the invention [0003] In order to meet the needs of locomotive weight reduction and noise reduction, overcome the deficiencies in the prior art, and provide a heat exchange device for railway transportation with strong heat dissipation capacity, light weight, small volume and low auxiliar...
