## Abstract

A cabinet is provided, including a case and a fin element. The case has at least one opening. The fin element is disposed in the case and is adjacent to the at least one opening and includes a main body and a plurality of fins, wherein the fins are disposed on the main body and face the at least one opening.

## Claims

### Claim 1

An electronic device, comprising:
a cabinet, comprising
a case having at least one opening; and
a fin element, disposed in the case and adjacent to the at least one opening, comprising a main body and a plurality of fins, wherein the fins are disposed on the main body and face the at least one opening;
a power converter disposed in the cabinet;
a fan disposed in the cabinet, wherein the fan is disposed on the power converter, and the fin element does not pass through the opening of the case;
a pipe passing through the case; and
a waterproof element disposed between the pipe and the case to seal a gap between the pipe and the case.

### Claim 2 (depends on 1)

The electronic device as claimed in claim 1, further comprising a sealing assembly disposed in the case, wherein the sealing assembly, the case and the fin elements form a space.

### Claim 3 (depends on 2)

The electronic device as claimed in claim 2, wherein the sealing assembly comprises a frame and a waterproof pad, wherein the waterproof pad is disposed between the frame and the fin element.

### Claim 4 (depends on 1)

The electronic device as claimed in claim 1, wherein the plurality of fins of the fin element comprises:
a plurality of first fins disposed on one side of the main body; and
a plurality of second fins disposed on the other side of the main body opposite the side with the first fins.

### Claim 5 (depends on 4)

The electronic device as claimed in claim 4, wherein the first fins are longer than the second fins.

### Claim 6 (depends on 5)

The electronic device as claimed in claim 5, wherein the first fins face the at least one opening of the case.

### Claim 7 (depends on 4)

The electronic device as claimed in claim 4, wherein the amount of the first fins is less than the amount of the second fins in a given area.

### Claim 8 (depends on 7)

The electronic device as claimed in claim 7, wherein the first fins face the at least one opening of the case.

### Claim 9 (depends on 1)

The electronic device as claimed in claim 1, wherein the case comprises a door, a plurality of side plates, a top plate and a bottom plate, the top plate is opposite from the bottom plate, and the door and the side plates are disposed between the top plate and the bottom plate, wherein the fin element faces one of the side plates.

### Claim 10 (depends on 9)

The electronic device as claimed in claim 9, wherein the bottom plate comprises a first hole corresponding to the fin element, and the first hole is aligned with the fin element along a direction that is perpendicular to the bottom plate.
