Patent ID: 8388141

Claim:
An electric apparatus comprising: a centrifugal fan that includes an impeller in a casing, and configured to draw air when the impeller rotates in the casing, and to have a blowoff channel of the air from the impeller in the casing, which spreads in a rotating direction of the impeller; and a first cooled part and a second cooled part that has a necessary cooling air capacity larger than that of the first cooled part, the first cooled part and the second cooled part being cooled by the air drawn by the centrifugal fan, wherein the casing comprises a drawing surface of the centrifugal fan having a first drawing area and a second drawing area that has a drawing speed higher than that of the first drawing area when the impeller rotates, wherein the drawing surface faces the first and second cooled parts, and wherein the second drawing area is closer to the second cooled part than to the first cooled part and wherein the drawing surface is arranged between the impeller and the first and second cooled parts.
