A heat dissipating structure for rectifiers of car alternators includes an upper cover, a rectifier assembly disposed under the upper cover, and a heat dissipating plate disposed below the rectifier assembly. The rectifier assembly is comprised of a plurality of rectifying elements and terminals, and a heat conductive assembly for receiving the rectifying elements. One side of the respective rectifying elements are connected to the terminals to constitute a rectifier circuit. The other side of the respective rectifying elements are connected to the heat conductive assembly, which is in turn connected to the heat dissipating plate. The heat conductive assembly is comprised of a heat conductive plate to which the rectifying elements may adhere, and a ceramic heat dissipating substrate disposed between the heat conductive plate and the heat dissipating plate. The ceramic heat dissipating substrate may efficiently dissipate heat and is compact in size, so that the overall size and weight of the heat dissipating structure may be reduced in size and weight.
