## Abstract

In one embodiment, an air guiding plate is attached to an enclosure with a plurality of vents defined therein. The air guiding plate includes a plurality of guiding holes defined therein. Each of the guiding holes is surrounded by a plurality of walls and includes an inlet with a large size, and an outlet with a small size. The outlets are in alignment with the vents of the enclosure. A size in cross section of each of the walls gradually decreases along a direction from the inlet to the outlet.

## Claims

### Claim 1

An air guiding plate attached to an enclosure with a plurality of vents of an electronic device, the air guiding plate comprising:
a plurality of guiding holes defined therein, each of the guiding holes surrounded by a plurality of walls, every two adjacent guiding holes comprising a common wall, each of the guiding holes comprising an inlet, and an outlet, the outlets in alignment with the vents of the enclosure, in cross-section, each of the walls increase in size along a direction from the inlet to the outlet.

### Claim 2 (depends on 1)

The air guiding plate as described in claim 1, wherein the cross-section of each of the walls is triangular-shaped.

### Claim 3 (depends on 1)

The air guiding plate as described in claim 1, wherein the cross-section of each of the walls is semi-ellipsoidal-shaped.

### Claim 4 (depends on 1)

The air guiding plate as described in claim 1, wherein a size of each of the guiding holes is gradually decreased from the inlet to the outlet.

### Claim 5 (depends on 1)

The air guiding plate as described in claim 1, further comprising an adhesive layer, wherein the adhesive layer is attached to a surface of the guiding plate with outlets, for easily attaching the guiding plate to the enclosure.

### Claim 6 (depends on 1)

The air guiding plate as described in claim 1, wherein a plurality of tabs defining apertures extends from the guiding plate, a plurality of fasteners extends through the apertures to engage with the enclosure.

### Claim 7

An electronic device comprising:
an enclosure comprising a pair of sidewalls opposite to each other, a plurality of vents defined in the sidewalls; and
a pair of air guiding plates each comprising a plurality of guiding holes defined therein, each of the guiding holes comprising an inlet with a large size, and an outlet with a small size corresponding to the corresponding vent of the enclosure, each of the guiding holes surrounded by a plurality of walls, every two adjacent guiding holes comprising a common wall, in cross-section, each of the walls increase in size along a direction from the inlet to the outlet, one of the air guiding plates attached to an outside surface of one of the sidewalls, the other one of the air guiding plates attached to an inside surface of the other of the sidewalls.

### Claim 8 (depends on 7)

The electronic device as described in claim 7, wherein the cross section of each of the walls is triangular-shaped.

### Claim 9 (depends on 7)

The electronic device as described in claim 7, wherein the cross section of each of the walls is semi-ellipsoidal-shaped.

### Claim 10 (depends on 7)

The electronic device as described in claim 7, wherein a size of each of the guiding holes is decreased from the inlet to the outlet.

### Claim 11 (depends on 7)

The electronic device as described in claim 7, wherein adhesive layers are attached to surfaces of the air guiding plates with outlets defined therein, for attaching the air guiding plate to the enclosure.

### Claim 12 (depends on 7)

The electronic device as described in claim 7, wherein a plurality of tabs defining apertures extends from the air guiding plate, a plurality of fasteners extends through the apertures to engage with the sidewalls of the enclosure.
