The invention discloses an electric reactor with aluminum alloy heat dissipation air flues. The electric reactor comprises a winding, wherein the winding is provided with an iron core clamping plate and an iron yoke is arranged on the iron core clamping plate. The electric reactor is characterized in that the aluminum alloy heat dissipation air flues are formed in the surface of the iron core clamping plate and in the winding. According to the electric reactor, an electric reactor structure design with a conventional air flue manner is broken through, and a glass fiber bracing heat dissipation manner is changed into an aluminum alloy heat dissipation manner; by using a good heat conduction performance of an aluminum alloy, a heat source is in direct contact with an aluminum alloy sheet material, and a fin is additionally arranged so that the heat dissipation area is enlarged; a smooth ventilation channel brings away relatively much heat so that the temperature rising of the electric reactor is relatively small; and noises are relatively low, the size is reduced, the structure is relatively compact, the efficiency of the electric reactor is improved and the cost of the electric reactor is reduced.
Description
