The invention discloses an automotive power steering electric controller for preventing the interior from being overheated. The automotive power steering electric controller comprises a PCB, a base and a cover plate. Conical supporting columns and a heat conduction seat in the shape of a right trapezoid are integrally formed above the base. The PCB is arranged on the conical supporting columns and located through two locating columns penetrating the PCB, and the PCB is fixed to the heat conduction seat by being combined with screws. The base and the cover plate are arranged together in a pressed manner. Mounting protrusions are inserted in corresponding mounting notches, and the conical supporting columns are located in the cover plate, so that the cover plate and the base are buckled more and more tightly. A triangular misloading prevention mark is arranged at the position, close to the right rear corner, of the top of the cover plate, and a plurality of strip-shaped heat conduction grooves extending left and right are formed in the back face of the base. The problems that the base and the cover plate slightly shake after being mounted, the PCB and the base slightly shake after being mounted, and the local temperature of the PCB is too high are effectively solved, and the cover plate is prevented from being placed reversely.
