PURPOSE: An expanding card for a computer is provided to enhance cooling efficiency by installing a cooling duct for surrounding a PCB board and a chip set. CONSTITUTION: A bracket(30) blocks a slot aperture, and at least one deflation hole(35) is formed in the bracket(30). A cooling duct(70A) partially surrounds a PCB board(20), and has an air suction hole(73A) and an air outflow hole(77) connected to the deflation hole(35) of the bracket(30). A cooling fan(40) is installed in the cooling duct(70A), and sucks air through the air suction hole(73A) and flows out cooling air through the air outflow hole(77).
