PURPOSE: A cooling system of a blower motor is provided to allow easy coupling work by allowing a cover to be detachably coupled to a housing part, and to reduce manufacturing cost by not using an additional assembling member. CONSTITUTION: A cooling system includes a case(31) having a blower wheel(34) and a blower motor(35) connected with the blower wheel installed therein; a cooling channel part(37) formed on one side of the case to supply cooling wind supplied from the blower wheel to the blower motor; a housing part(40) comprising a main body part having size corresponding with a bottom of the case, a receiving part(41) extended from the main body part to form a space receiving the blower motor, and a cooling wind outlet extended from the receiving part to the main body part; one fixing unit formed on the housing part; a cover(400) detachably coupled to the housing part, and having one end coupled to the cooling wind outlet, and the other end connected with the cooling channel part to form a channel through which cooling wind is delivered therein; and a coupling part formed integrally with the cover, and coupled to the fixing unit in a single direction to fix the cover to the housing part.
