PURPOSE: An inlet duct for blower unit is provided to prevent deterioration of cooling efficiency and achieve a simple structure by arranging a door for controlling an internal and external air flow to move slidably. CONSTITUTION: An inlet duct comprises a main body(11) having at a vertical surface thereof an internal air inlet(12) and at a horizontal surface thereof an external air inlet(13) so as to allow external and internal air to be fed inside the main body, a door(14) installed to move slidably within the main body and which selectively closes/opens the internal air inlet and external air inlet so as to feed external and internal air into the main body, and a door feed member for slidably transferring the door in such a manner that the door opens the internal air inlet during an internal air mode and opens the external air inlet during an external air mode.
