COOLING SYSTEM FOR OIL-COOLING MOTOR

The present invention relates to a cooling system for an oil-cooling motor. The cooling system comprises a cooling pipe, a shell, a balance end plate, a bearing, an oil return tank, a rotor, a stator iron core, and a shaft. A tubular cavity is provided inside the shell. Three spraying holes are disposed on the cooling pipe. The cooling oil is introduced into the cooling pipe from the tubular cavity. Part of the cooling oil is sequentially sprayed out of the three spraying holes of the cooling pipe, and is subjected to direct convective heat exchange with the stator iron core and a coil end portion. The rest cooling oil flows out of an outlet of the cooling pipe, flows to the bearing along the tubular cavity, and is sprayed to the shaft, the balance end plate, and the coil end portion. According to the present invention, an iron core of the rotor, a magnetic steel, and other heating bodies are indirectly cooled by cooling the shaft and the balance end plate, and the cooling effect is better.
