## Abstract

A liquid-cooled cooling device with a channel includes: a base having a surface which a slender groove is concavely disposed on, with a spoiler disposed on a portion of a wall of the groove and extending for a predetermined length in an axial direction of the groove; and a cover unit coveringly disposed at the base to cover the groove and thereby form a channel which a liquid passes through, with the channel not completely closed by the spoiler. One of the base and the cover unit has a liquid inlet and a liquid outlet. The liquid inlet is in communication with one end of the channel. The liquid outlet is in communication with the other end of the channel.

## Claims

### Claim 1

A liquid-cooled cooling device with a channel, comprising:
a base having a surface which a slender groove is concavely disposed on, with a spoiler disposed on a portion of a wall of the groove and extending for a predetermined length in an axial direction of the groove; and
a cover unit coveringly disposed at the base to cover the groove and thereby form a channel which a liquid passes through, with the channel not completely closed by the spoiler,
wherein one of the base and the cover unit has a liquid inlet and a liquid outlet, the liquid inlet being in communication with an end of the channel, and the liquid outlet being in communication with another end of the channel.

### Claim 2 (depends on 1)

The liquid-cooled cooling device with a channel according to claim 1, wherein the spoiler and the cover unit are spaced apart by a predetermined distance to form a space.

### Claim 3 (depends on 1)

The liquid-cooled cooling device with a channel according to claim 1, wherein the groove has a bottom wall and two sidewalls, with the spoiler disposed on the bottom wall.

### Claim 4 (depends on 1)

The liquid-cooled cooling device with a channel according to claim 1, wherein the spoiler and the base are integrally formed.

### Claim 5 (depends on 1)

The liquid-cooled cooling device with a channel according to claim 1, wherein the spoiler comprises a plurality of fins.

### Claim 6 (depends on 5)

The liquid-cooled cooling device with a channel according to claim 5, wherein the plurality of fins of the spoiler are slender, extend in an axial direction of the groove, and are parallel to the axial direction of the groove.

### Claim 7 (depends on 6)

The liquid-cooled cooling device with a channel according to claim 6, wherein the plurality of fins of the spoiler are parallel and spaced apart by a predetermined distance.

### Claim 8 (depends on 7)

The liquid-cooled cooling device with a channel according to claim 7, wherein the plurality of fins of the spoiler are divided into sections such that adjacent sections of the plurality of fins are spaced apart by a predetermined distance.

### Claim 9 (depends on 7)

The liquid-cooled cooling device with a channel according to claim 7, wherein the groove has a bottom wall and two sidewalls, with the spoiler disposed on the bottom wall in such a manner that a distance between the spoiler and each of the two sidewalls is greater than a distance between two adjacent said fins.

### Claim 10 (depends on 7)

The liquid-cooled cooling device with a channel according to claim 7, wherein the plurality of fins of the spoiler are of different heights.

### Claim 11 (depends on 1)

The liquid-cooled cooling device with a channel according to claim 1, wherein the liquid inlet and the liquid outlet are disposed on the base.
