Abstract

The utility model relates to a composite cooler of a main transformer for an electric locomotive, comprising a framework, a water cooler and an oil cooler, the water cooler is arranged above the oil cooler, the water cooler and the oil cooler are both arranged in the framework, a plurality of fins of a water heat-dissipating plate and an oil heat-dissipating plate are arranged on the water cooler and the oil cooler, the fin of an air heat-dissipating plate is arranged on the windward side of the composite cooler, the plurality of fins of the water cooler and the oil cooler are a plurality of transversely double-cross trapezoidal spoilers, the fin of the air heat-dissipating plate is an alternately zigzag ripple piece. Therefore, the utility model has the advantages of simple manufacture, convenient maintenance and compact structure, the heat dissipating capacity of the water cooler is between 130 and 150 KW and the total heat dissipating capacity is more than 250 KW under the conditions that the wind temperature is 40 DEG C and the air flowrate is 6.5 m3/s through the testing of Hefei universally mechanical product inspection institute.

Description

The electric locomotive main transformer composite cooler

The utility model relates to a kind of electric locomotive main transformer composite cooler, belongs to the heat-exchange apparatus class.

The main transformer of AC variable speed transmission locomotive and the cooler of main convertor, it is the vitals that guarantees main transformer and main convertor operate as normal, the cooler of in AC variable speed transmission locomotive, working under the certain environmental conditions, constantly have new requirement to satisfy to its structure, performance, the application is promptly improved on the basis of " 00224265.6 " number patent " composite cooler " and is finished.

The purpose of this utility model provides a kind of water-cooled, the compound cooler of oil cooling, on the basis of the power that as far as possible reduces the cooling channel motor, has increased the particularly power of water-cooled cooling of cooler again.

The purpose of this utility model realizes in the following manner, the utility model comprises skeleton and water, oil cooler, water cooler is installed in the oil cooler top, water, oil cooler all are contained in the skeleton, and optimal design water, oil cooling but heating panel wing and air heating panel wing shape and arrangement mode, water, oily heating panel fin are the trapezoidal spoiler of horizontal dual crossing, and air heating panel fin is the jagged shape corrugated plate.

Characteristics of the present utility model are simple, easy to maintenance, the compact conformation of its manufacturing, and water-cooled, each tool independent loop of oil cooling detect expert's detection of institute through Hefei universal machine product, at 40 ℃ of wind-warm syndrome, air quantity 6.5m ³During/s, the water cooler heat dissipation capacity is 130-150KW, and the heat radiation total amount is not less than 250KW.

Accompanying drawing 1 is a structural representation of the present utility model, Fig. 2 is the shape schematic diagram of air heating panel fin, Fig. 3 is the partial enlarged drawing of Fig. 2, Fig. 4 is the shape schematic diagram of water, oily heating panel fin, be numbered skeleton 1, water cooler 2, outlet pipe 3, water inlet pipe 4, air heating panel fin 5, flowline 6, oil cooler 7, oil inlet pipe 8 among the figure, water, oily heating panel fin 9.

Embodiment of the present utility model is provided by accompanying drawing, below in conjunction with the description of drawings present embodiment, with reference to accompanying drawing, the utility model comprises skeleton 1, water cooler 2, oil cooler 7, water cooler 2 are contained in oil cooler 7 tops, water, oil cooler all are contained in the skeleton, water, oily heating panel fin 9 are housed on the water cooler 2, water, oily heating panel fin 9 also are housed on the oil cooler 7, air heating panel fin 5 is contained in the place, windward side of composite cooler, air heating panel wing 5 is the jagged shape corrugated plate, and water, oily heating panel fin 9 are the trapezoidal spoiler of horizontal dual crossing.
