Automobile generator regulator convenient for heat dissipation

Abstract

The utility model discloses an automobile generator regulator convenient for heat dissipation, which is characterized in that an integrated heat dissipation plate, special-shaped heat dissipation fins and heat dissipation holes are arranged at the tops of a circuit unit bracket and a carbon brush holder; therefore, heat generated by working of the carbon brush and the circuit unit can be quickly dissipated through the integrated heat dissipation plate, the special-shaped heat dissipation fins and the heat dissipation holes, and the heat dissipation holes are distributed between every two adjacent special-shaped heat dissipation fins. The bent part of the upper half part of each special-shaped heat dissipation fin can shield the adjacent heat dissipation hole, and a metal wire dustproof net is arranged above the heat dissipation hole, so that external dust and impurities can be prevented from entering the regulator through the heat dissipation hole, and a gap is reserved between the bent parts of every two adjacent special-shaped heat dissipation fins. Therefore, heat dissipated from the heat dissipation holes can be quickly dissipated through a heat dissipation channel formed by two adjacent special-shaped heat dissipation fins and a gap above the heat dissipation channel, and the overall heat dissipation speed of the generator regulator can be improved.

Description

Technical Field

[0001] The present application relates to the technical field of generator regulators, and in particular to an automobile generator regulator that facilitates heat dissipation. Background Art

[0002] Generators, devices that convert mechanical energy into electrical energy, are widely used in the industrial and automotive sectors. However, the generator's output voltage often fluctuates with speed, creating uncertainty in the device's proper operation. To ensure stable output voltage at varying speeds, a regulator is typically required. This regulator controls the rotor's magnetic field by adjusting the generator's rotor excitation current, thereby stabilizing the output voltage.

[0003] In the prior art, generator regulators typically include circuit units that generate significant heat during operation. To ensure proper operation, aluminum alloy heat sinks are typically installed on the regulator's surface to dissipate this heat naturally. However, relying solely on heat sinks for natural heat dissipation is limited, especially in high-load operating environments, where heat accumulation can adversely affect the normal operation of the circuit units.

[0004] Furthermore, the carbon brushes in an automotive alternator regulator contact the generator rotor slip rings to transmit current. During the transmission of high current and high-power signals, the carbon brushes generate a certain amount of heat due to contact resistance. This heat is typically evenly distributed across each brush. Current heat dissipation methods rely on the end holes near the barrel of the carbon brush holder on the alternator regulator. However, this method is inefficient, resulting in slow heat dissipation and impacting the regulator's operational stability.

[0005] It can be seen that the existing generator regulator has certain limitations in heat dissipation, and an improvement solution that can improve heat dissipation efficiency is urgently needed to ensure the stability and reliability of the regulator under high load operation.
