The driving assembly is used for driving the first clutch assembly to be meshed with or separated from the first fixed meshing sleeve and driving the second clutch assembly to be meshed with or separated from the second fixed meshing sleeve; the air cooling mechanism comprises a heat dissipation fan arranged at the air inlet, the liquid cooling mechanism comprises a circulating pump, a cooling coil and a cooling water tank, the situation that the span of the heating range of the generator is large can be effectively handled, effective heat dissipation can be carried out, the power consumed by heat dissipation can be effectively controlled, and the use reliability is improved.

Description

technical field [0001] The invention relates to the technical field of generator heat dissipation, in particular to an automatic heat dissipation and cooling mechanism for a generator of a new energy vehicle. Background technique [0002] In recent years, the proportion of new energy vehicles has become higher and higher. Currently, new energy vehicles are generally equipped with energy recovery systems, that is, a part of energy is recovered through self-braking, and the energy is converted into electrical energy through a generator and stored in a power battery. Only when the car brakes by itself will it drive the generator to generate electricity. In some crowded roads, the car needs to brake frequently, and the working frequency of the generator is high, so the self-heating is serious. The working frequency of the generator is very low, so it will not generate much heat, and there is no need to dissipate heat. Therefore, there is a large span in the heat generation of th...

Problems solved by technology

Only when the car brakes by itself will it drive the generator to generate electricity. In some congested roads, the car needs to brake frequently. The working frequency of the new energy vehicle generator is very low, so it will not generate much heat, and there is no need for heat dissipation. Therefore, there is a large span in the heat generation of the new energy vehicle generator, and the current heat dissipation mechanism of the new energy vehicle generator cannot effectively cope with this large span. In the case of heat generation, either the heat dissipation consumes a large amount of power, or cannot effectively dissipate heat, which affects the service life of the generator and leads to low reliability
