Abstract

The invention discloses a heat dissipation apparatus used for an electric vehicle motor. The heat dissipation apparatus is reasonable and simple in structure, low in production cost and convenient tomount; by adoption of powerful wind power heat dissipation, effective heat dissipation can be performed on a permanent magnet motor, thereby greatly improving performance of the permanent magnet motor; the heat of the electric vehicle motor is dissipated through a heat dissipation cover shell and heat dissipation sheets; an air-blowing fan and a first circulation fan blow hot air; the first circulation fan moves left and right under driving of a screw rod, so that hot air can be blown quickly; a rack wheel drives exhaust fans on two pinions to realize quick air exhausting; for further improving the heat dissipation effect, a condenser can lower the temperature in a third heat dissipation chamber through a snake-shaped pipe; a rotary motor drives a gear and the gear drives a rack to realizereciprocating movement of a second circulation fan; the second circulation fan blows cold air to the heat dissipation cover shell to realize cooling; and by virtue of the technical scheme, strong heat dissipation to the permanent magnet motor is realized.

Description

Technical field: [0001] The invention relates to the technical field of electric vehicles, in particular to a cooling device for electric vehicle motors. Background technique: [0002] In pure electric vehicles, the electric motor replaces the traditional engine, and the vehicle is driven by converting electrical energy into mechanical energy. The performance of the motor has a lot to do with temperature changes. The high-speed operation of the permanent magnet motor generates a lot of heat. The performance of the motor is reduced, so that the efficiency of the motor cannot be fully utilized. At present, most of the heat dissipation methods of permanent magnet motors are air-cooled. This kind of air-cooled system has poor cooling effect, so a new technology is needed to make up for this deficiency. Invention content: [0003] The object of the present invention is to provide a cooling device for electric vehicle motors in order to solve the above problems, which solves the...
