The specific embodiment
As shown in Figure 1 and Figure 2.The special-purpose Non-energy-consumption cooling system of the utility model motor in electric automobile comprises by fluid dividing cover 4, head-on incoming flow air quantity manifold cylindrical section 5, head-on incoming flow air quantity manifold diffuser 6, the head-on incoming flow air quantity manifold 9 that consists of of incoming flow air quantity manifold contraction section 7 and grille guard 8 head-on.Head-on incoming flow air quantity manifold diffuser 6, the incoming flow air quantity manifold contraction section 7 that heads on are the truncated cone cover body, and head-on incoming flow air quantity manifold diffuser 6 is captiveed joint with the portlet of the incoming flow air quantity manifold contraction section 7 that heads on.Head-on incoming flow air quantity manifold cylindrical section 5 is the cylindrical shape cover body, and head-on the large port of incoming flow air quantity manifold diffuser 6 is connected with the incoming flow air quantity manifold cylindrical section 5 that heads on.Grille guard 8 is arranged on the large port of the incoming flow air quantity manifold contraction section 7 that heads on.The conical fluid dividing cover 4 on wind guide edge edge is arranged in the incoming flow air quantity manifold diffuser 6 that heads on.Motor 3 is not for the AC and DC motor of cooling fan blade.Cooling fan blade and the tail defense cover of conventional motor are removed, and motor output shaft 1 shortens relatively, motor 3 bodies and 2 coaxial connections of reducing gearbox.Increase the head-on incoming flow air quantity manifold 9 of battery-driven car, and keep 10 ㎜ intervals to arrange with motor 3 tail ends, the general layout location can add necessary support connecting element during by entrucking, to protect the normal cooling of motor 3.But guarantee that the battery-driven car profile of facining the wind is constant.
Head in heating and the battery-driven car motion during motor 3 work dynamic equilibrium relation of incoming flow blast cooling thermal discharge relates to the reasonable utilization of battery-driven car head resistance and don't affects the normal operation of battery-driven car.
Groundwork: the heating heat of motor becomes useful cooling wind energy use with the part wind energy that heads on flow resistance of battery-driven car during the battery-driven car operation, and its heat is drained.Cancellation is the fan cooling or the water cooling system that carry of motor originally, has saved to carry the electric energy that electric energy that fan consumes or water-cooling system consume, and has made the weight reduction of battery-driven car further reduce the energy consumption of operation.Battery-driven car always will produce when operation and head on flow resistance, it exists all the time, the part of resistance wind energy is used for cooling motor just becomes salvaging, owing to do not change the profile of battery-driven car, so the head resistance of battery-driven car does not change, this theory is core theory of the present utility model.
