Abstract

A power supply fan, especially for a computer, comprises a fan case for a fan blower, the power supply fan being mounted on a power supply case surrounding a power supply unit and the fan case being at least partially arranged on the power supply case. The power supply fan is dimensioned in such a manner that it extends over at least one edge of a surface on which the power supply fan is fastened in such a manner that the interior of the power supply case and any electronic components adjacent to the power supply unit are supplied with an air stream.

Claims

1. Power supply fan, particularly for computers, having a fan case for a fan blower, wherein the power supply fan is mounted externally to a power supply unit case enclosing a power supply unit and the fan case is arranged at least partially on the power supply unit case, characterized in that the power supply fan is dimensioned such that it extends at least beyond one edge of a surface to which the power supply fan is attached so that both the interior of the power supply unit case and electronic components adjacent to the power supply unit are supplied with an air stream.

2. Power supply fan from claim 1, wherein the power supply fan is dimensioned such that it extends beyond one edge of a surface on which the power supply fan is arranged, said edge facing electronic components lying below the power supply unit.

3. Power supply fan from claim 1, wherein the power supply fan extends beyond two edges of a surface on which the power supply fan is arranged, wherein the two edges of the surface touch at least one common edge point.

4. Power supply fan from claim 1, wherein the power supply unit case has at least one projecting tab on an end face on which the power supply fan is arranged, said edge extending beyond the end face of the power supply fan and the fan case is attached at least partially to this projecting tab.

5. Power supply fan from claim 1, wherein the fan case is arranged partially on the power supply unit case and partially on the mother board of the computer.

6. Power supply fan from claim 2, wherein the power supply fan extends beyond two edges of a surface on which the power supply fan is arranged, wherein the two edges of the surface touch at least one common edge point.

7. Power supply fan from claim 2, wherein the power supply unit case has at least one projecting tab on an end face on which the power supply fan is arranged, said edge extending beyond the end face of the power supply fan and the fan case is attached at least partially to this projecting tab.

8. Power supply fan from claim 3, wherein the power supply unit case has at least one projecting tab on an end face on which the power supply fan is arranged, said edge extending beyond the end face of the power supply fan and the fan case is attached at least partially to this projecting tab.

9. Power supply fan from claim 6, wherein the power supply unit case has at least one projecting tab on an end face on which the power supply fan is arranged, said edge extending beyond the end face of the power supply fan and the fan case is attached at least partially to this projecting tab.

10. Power supply fan from claim 2, wherein the fan case is arranged partially on the power supply unit case and partially on the mother board of the computer.

11. Power supply fan from claim 3, wherein the fan case is arranged partially on the power supply unit case and partially on the mother board of the computer.

12. Power supply fan from claim 4, wherein the fan case is arranged partially on the power supply unit case and partially on the mother board of the computer.

13. Power supply fan from claim 6, wherein the fan case is arranged partially on the power supply unit case and partially on the mother board of the computer.

14. Power supply fan from claim 7, wherein the fan case is arranged partially on the power supply unit case and partially on the mother board of the computer.

15. Power supply fan from claim 8, wherein the fan case is arranged partially on the power supply unit case and partially on the mother board of the computer.

16. Power supply fan from claim 9, wherein the fan case is arranged partially on the power supply unit case and partially on the mother board of the computer.
