## Abstract

Provided is an electronic device. The electronic device includes a housing, a heat generating element, a plurality of fans, and a guide structure. The housing includes a first outlet. The heat generating element is disposed in the housing. The fans are disposed in the housing. Each fan includes a second outlet. The second outlets at least partially face the interior of the housing. The guide structure is disposed in the housing, and is at least partially located between the fans. The guide structure at least partially extends toward the first outlet.

## Claims

### Claim 1

An electronic device, comprising:
a housing, comprising a first outlet;
a heat generating element, disposed in the housing;
a plurality of fans, disposed in the housing, each fan of the plurality of fans comprises a second outlet, the second outlets at least partially face an interior of the housing; and
a guide structure, disposed in the housing, and at least partially located between the plurality of fans, the guide structure comprising a guiding portion and an extending portion connected to the guiding portion, the guiding portion and the plurality of fans together defining a chamber, the extending portion extending toward the first outlet to divide the chamber into two sub-chambers, and the heat generating element being located in one of the two sub-chambers.

### Claim 2 (depends on 1)

The electronic device according to claim 1, wherein the second outlets separately at least partially face the guide structure.

### Claim 3 (depends on 1)

The electronic device according to claim 1, wherein the plurality of fans comprise two fans, the extending portion is at least partially located between the two fans, and each second outlet is in communication with a corresponding sub-chamber of the two sub-chambers.

### Claim 4 (depends on 1)

The electronic device according to claim 1, wherein an extending direction of the extending portion is perpendicular to the first outlet.

### Claim 5 (depends on 1)

The electronic device according to claim 1, wherein the first outlet is in communication with the two sub-chambers.

### Claim 6 (depends on 1)

The electronic device according to claim 1, wherein the extending portion is located between the guiding portion and the first outlet.

### Claim 7 (depends on 1)

The electronic device according to claim 1, wherein the first outlet is located between the first inlets.

### Claim 8 (depends on 1)

The electronic device according to claim 1, wherein each fan of the plurality of fans comprises a first inlet and a second inlet, the first outlet and the first inlets are coplanar with each other, and each second inlet is perpendicular to a corresponding first inlet.
