The invention discloses a heat conductive type electric power steering controller. The controller comprises a printed circuit board (PCB), a base and a cover plate. Tapered support columns and a heat-conducting seat in a right trapezoid shape are integrally formed on the base. The PCB is disposed on the tapered support columns and located through two locating columns penetrating through the PCB, and the PCB is fixed to the heat-conducting seat by the combination with screws. The base and the cover plate are arranged together in a press fit mode. Mounting protrusions are inserted into corresponding mounting notches, the tapered support columns are disposed in the cover plate, and the cover plate and the base are made to be fastened tighter and tighter. Four columns which extend upwards and are distributed in a rectangular shape are integrally formed on the base, threaded mounting blind holes with the number identical to the number of the columns and the positions corresponding to the positions of the columns are formed in the back of the base, and multiple strip-shaped heat-conducting grooves extending left and right are formed in the back of the base. By means of the structure of the heat conductive type electric power steering controller, the problems of slight shaking between the base and the cover plate as well as between the PCB and the base after mounting and too high local temperature of the PCB are effectively solved; besides, the dustproof effect is achieved.
