The invention discloses an automotive power-assisted steering electric controller with a heat conducting seat, which comprises a PCB (Printed Circuit Board), a base and a cover board, wherein a conical support column and the heat conducting seat are integrally formed on the base; the PCB is arranged on the conical support column, is positioned through two positioning columns penetrating through the PCB, and is then fixed on the heat conducting seat by combining with screws; the left side and right side of the base are respectively provided with installation notches; installation bulges, which have the same quantity with the installation notches, corresponding to the installation notches in position and are matched with the installation notches in size, are arranged on the left side wall and right side wall of the cover board; the base and the cover board are pressed together; the installation bulges are inserted into the corresponding installation notches; the conical support column is positioned in the cover board and enables the cover board and the base to be fastened tighter and tighter; and the position, close to a right back corner, of the top of the cover board, is provided with a triangular anti-misloading mark. The structure effectively avoids the problem of unfirm connection 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, and prevents the cover board from being installed in an inverted way.
