Problems solved by technology

[0003] The motor rotor is an essential part of the motor. Its heat dissipation efficiency determines the performance of the motor. The heating of the rotor itself and the heat radiation of the stator may cause partial or overall overheating of the rotor. Among them, the cast aluminum rotor is a common For the rotor, in the prior art, the coolant can only dissipate heat on the surface of the rotor and the stator, and cannot achieve a good cooling effect on the inside of the rotor, and poor cooling of the rotor will cause the motor to heat up and the temperature rise will be too high. At this time, the efficiency and output of the motor will drop sharply, and the higher temperature will also affect the lubrication and insulation inside the motor. In extreme cases, it may even burn out the motor

Abstract

According to the cast-aluminum rotor of the new energy automobile and the heat dissipation device of the cast-aluminum rotor, a rotating shaft is provided with a through hole, the cast-aluminum rotor is connected with a gearbox assembly through an oil guide pipe of the heat dissipation device, so that lubricating oil can enter the cast-aluminum rotor through the through hole, lubricating oil in a gearbox enters the through hole in the rotating shaft through the oil guide pipe, and the lubricating oil flows back into the gearbox through the through hole, so that the function of the lubricating oil is continuously realized, and dual utilization of resources is realized; the cooling device further comprises an oil pump, a cooling part and a control system, the oil pump is connected to the oil guide pipe, the controller is in signal connection to a motor controller corresponding to the rotor, and the controller can obtain working signals of the rotor; and the controller is in signal connection with the oil pump, and after the controller detects that the rotor works, the oil pump and the heat dissipation piece are started, so that lubricating oil in the gearbox can flow in the oil guide pipe and the through hole, and automatic control heat dissipation is achieved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a cast aluminum rotor of a new energy vehicle and a heat dissipation device thereof. Background technique [0002] The motor of the new energy vehicle is in continuous operation, the cooling solution of the motor in the vehicle usually includes a coolant reservoir, which stores the coolant of some special materials, and the coolant is delivered to one or more other components in the vehicle via hoses . [0003] The motor rotor is an essential part of the motor. Its heat dissipation efficiency determines the performance of the motor. The heating of the rotor itself and the heat radiation of the stator may cause partial or overall overheating of the rotor. Among them, the cast aluminum rotor is a common For the rotor, in the prior art, the coolant can only dissipate heat on the surface of the rotor and the stator, and cannot achieve a good cooling effect on the inside of the rotor,...
