The invention discloses an electric vehicle motor heat dissipation structure which is characterized by comprising a middle motor arranged in a closed cavity, a left side covering assembly and a right side covering assembly are arranged on the left side and the right side of the middle motor, a plurality of air inducing openings are formed in the right side covering assembly in a forward mode, and air guiding plates of the air inducing openings protrude outwards by 5 mm from front to back. A motor partition plate is arranged between the middle motor and the left side covering assembly, a main air channel is formed between the motor partition plate and the left side covering assembly, the main air channel is through in the front-back direction, and the motor partition plate is provided with a backward air outlet. The position of the motor partition plate corresponding to the air outlet protrudes towards one side of the left covering assembly. The beneficial effects of the invention are that wind energy generated during vehicle driving is utilized to introduce cooling air to perform 360-degree cooling on the motor shell through the combined action of the main air inlet channel and the auxiliary air inlet channel which are specially designed, and more heat energy is taken away by changing the type of air flow.

    本发明公开了一种电动车电机散热结构,其特征在于:包括设置在封闭腔的中置电机,中置电机左右设置有左侧覆盖组件、右侧覆盖组件,右侧覆盖组件上具有多个朝前方开设引风口,多个引风口的导风板从前至后向外突出5mm,导风板与正前方的夹角从前至后依次减小5°,中置电机与左侧覆盖组件之间设置有电机隔板,电机隔板与左侧覆盖组件之间具有主气道,主气道前后贯通,电机隔板上具有朝后方的出风口,电机隔板对应出风口的位置向左侧覆盖组件一侧突出。本发明的有益效果包括利用车辆行驶时产生的风能通过特殊设计的主进气道及辅助进气道的共同作用,引入冷却空气对电机壳体360°进行冷却,并通过改变气流的型式带走更多的热能。
