Description

technical field [0001] The invention relates to a heat dissipation structure of a motor coil, in particular to a heat dissipation structure of a motor coil used in an electric motor to cool down the temperature of the motor. Background technique [0002] Most of the existing vehicles use internal combustion engines as the power source. However, due to the gradual depletion of fossil fuels in the future, as well as the air pollution and carbon dioxide emissions caused by fossil fuels, electric vehicles are gradually being valued and popularized in the market. [0003] Electric vehicles use motors instead of internal combustion engines as the power source. In the past, electric vehicles were limited by factors such as battery storage capacity and motor output power, which made the endurance and power performance of electric vehicles inferior to those of internal combustion engine vehicles, making electric vehicles less susceptible to The market accepts it. However, in recent ...
