On the basis of the three-phase stator winding of the ordinary AC generator, the number of winding turns is increased and the terminal is led out, and a set of three-phase bridge rectifier is added. At low speed, the original winding and the increased winding are output in series, and at higher speeds, only the original three-phase winding is output. The automobile generator will generate a lot of heat energy when working, and a heat sink is needed to remove the heat. Therefore, it is necessary to propose a heat sink for the automobile generator.

In addition, it is not convenient to increase the size of the heat sink fins according to the working condition and heat accumulation of the generator, which will easily cause the problem of insufficient heat dissipation efficiency, generator power reduction or burning.

Such a setting can perform preliminary heat dissipation work through the thermal conductivity of the sheet 1 when the device is fixed to the outer wall of the generator in conjunction with the sheet 1. After working for a period of time, dust and stains are easily attached to the outer wall of the sheet 1. Excessive accumulation will seriously affect the heat dissipation efficiency and effect of the sheet 1. The slider 401 can be used in conjunction with the sliding structure of the arc groove 3.
