Description

Technical Field

[0001] The present application relates to the technical field of automobile accessories, and in particular to a generator regulator with rapid heat dissipation. Background Art

[0002] The automobile generator regulator, also known as the voltage regulator, is an electronic component whose main function is to automatically adjust the output voltage and current of the generator to ensure that the automobile battery obtains the appropriate charging current and voltage, thereby ensuring the normal operation of the automobile electrical system. The generator regulator is provided with a circuit unit. In order to ensure that the circuit unit can work normally, a heat sink is provided on the surface of the generator regulator to contact the circuit unit so that the heat generated by the circuit unit when working can be quickly dissipated; in addition, the function of the carbon brush in the automobile generator regulator is to contact the generator rotor slip ring to achieve current output, and can adjust the current to stabilize the generator output voltage. In this process, sliding friction occurs between the carbon brush and the slip ring, and this friction generates heat. In addition, when the carbon brush transmits large current and high-power signals, heat will also be generated due to the existence of contact resistance. This heat is usually evenly distributed on each carbon brush. At present, the heat generated by the carbon brush is usually dissipated through the end hole of the carbon brush holder close to the barrel on the generator regulator, which will seriously slow down the heat dissipation speed and affect the working stability of the regulator.
