Abstract: A liquid-cooled cooling device with a channel includes a base a cover unit which is a cylindrical tube sleeved onto the surface of the base. The base has a surface which a 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. The cover unit covers the groove and thereby forms 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.

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.
