The invention discloses an electric power-assisted steering controller with high heat conducting speed, which comprises a PCB (printed circuit board), a base and a cover board, wherein a conical support column and a heat conducting seat in a right trapezoid shape are integrally formed on the base; the PCB is arranged on the conical support column, is positioned through two positioning columns passing through the PCB, and is then fixed on the heat conducting seat by combining with screws; the cross sections of the two positioning columns are different; the base and the cover board are pressed together; the conical support column is positioned in the cover board and ensures that the cover board and the base are fastened tighter and tighter; four circular columns which are in rectangular distribution and extend upwards are integrally formed on the base, the back side of the base is provided with four thread installation blind holes corresponding to the four circular columns in position, and the back side of the base is provided with a plurality of strip-shaped heat conducting slots extending left and right. The structure effectively avoids the problem of slight shaking between the base and the cover board as well as between the PCB and the base after installation and effectively avoids the problem of overhigh local temperature of the PCB, has a dustproof effect, and prevents the PCB from being installed oppositely.
