The invention discloses an electric power steering controller with the function of rapid heat dissipation. The electric power steering controller comprises a PCB, a base and a cover board, wherein conical support columns and a heat conducting seat in the shape of a right-angled trapezoid are integrally formed on the base; the PCB is arranged on the conical support columns, positioned through two positioning columns penetrating through the PCB, and then fixed on the heat conducting seat through screws in a combining manner; the base and the cover board are mounted together in a pressing manner, and the conical support columns are positioned in the cover board, so that the cover board and the base are buckled more and more tight; a plurality of bar-shaped heat conducting grooves extending left and right are formed in the back of the base. According to the structure, slight shake between the base and the cover board and slight shake between the PCB and the base after the base, the cover board and the PCB are mounted are effectively avoided, and the problem that the local temperature of the PCB is too high is effectively solved.
