Patent ID: 7515413

Claim:
A fan device which is field replaceable within an electronic system; the electronic system having a chassis, electronic circuitry, and a power source; the fan device comprising: an electrical connector constructed and arranged to electrically connect to the power source of the electronic system; a fan coupled to the electrical connector, the fan being constructed and arranged to provide cooling to the electronic circuitry of the electronic system when the fan receives a power signal from the power source of the electronic system through the electrical connector; and an attachment assembly coupled to the fan, the attachment assembly being constructed and arranged to control attachment of the fan device to the chassis of the electronic system within an air duct defined by the chassis, the fan defining (i) a near side which faces the electronic circuitry, (ii) a far side which faces away from the electronic circuitry, (iii) an airflow axis which extends from the near side to the far side along an airflow direction, and (iv) a fan profile which is substantially perpendicular to the airflow axis, the fan being disposed substantially between the electronic circuitry and the attachment assembly when the fan device attaches to the chassis within the air duct defined by the chassis, the attachment assembly having a width which closely mirrors a width of the fan profile; wherein the attachment assembly includes a frame body which is constructed and arranged to hold an electromagnetic interference shield in a fixed position relative to the fan.
