Abstract
A heat dissipation device by liquid cooling includes a casing, which has a spacing wall to form a channel therein. The casing has sidewalls and the inner surfaces of the sidewalls and the surface of the spacing wall are provided with a plurality of first toothed projections. An upper cover covers the casing and includes a liquid outlet and a liquid inlet at locations respectively corresponding to two corners of the channel. A plurality of posts are alternately placed inside the channel and a surface of each post is provided with a plurality of second toothed projections. Thereby, a liquid flowing inside the channel of the casing strikes the first and second toothed projections to promote flowing turbulence and increase heat transfer surface areas for heat dissipation.

A heat dissipation device by liquid cooling, comprising:
- a casing having a spacing wall to forming a channel therein, the casing also having sidewalls, and inner surfaces of the side walls and a surface of the spacing wall being provided with a plurality of first toothed projections;
- an upper cover covering the casing and including a liquid outlet and a liquid inlet at locations respectively corresponding to two corners of the channel;
- and
- a plurality of posts, alternately placed inside the channel, a surface of each post being provided with a plurality of second toothed projections, thereby a liquid flow inside the channel of the casing strikes the first and second toothed projections to promote flowing turbulence and increase heat transfer surface areas for heat dissipation.
