Abstract: A manifold liquid drainage system includes a first liquid drain body and a manifold assembly. The first liquid drain body includes a first hollow flow channel and a plurality of first openings. The manifold assembly is fixed to at least one of the first openings and communicates with the first hollow flow channel, wherein the manifold assembly includes a pipe, a quick release joint, an electronic flow valve, and a control circuit board. The pipe is connected to one of the openings. The electronic flow valve is installed between the pipe and the quick release joint. The control circuit board controls the electronic flow valve to regulate the liquid flow through the pipe.

Abstract: A heat dissipation module includes a main vapor chamber, at least one auxiliary vapor chamber, a main heat dissipation fin set and at least one auxiliary heat dissipation fin set. The auxiliary vapor chamber is in fluid communication with the main vapor chamber, the main heat dissipation fin set is installed on the main vapor chamber, the auxiliary heat dissipation fin set is connected to the auxiliary vapor chamber, and the auxiliary vapor chamber is arranged between the main heat dissipation fin set and the auxiliary heat dissipation fin set.

Abstract: An anti-wear screw includes a U-shaped anti-wear clip and a locking screw. The U-shaped anti-wear clip is used to clamp on a heat dissipation substrate, and the locking screw is passed through the U-shaped anti-wear clip to fix the heat dissipation substrate. In addition, the anti-wear screw further includes a pressure spring installed between the locking screw and the U-shaped anti-wear clip to exert pressure on the U-shaped anti-wear clip and the heat dissipation substrate.

Abstract: A heat dissipation device is provided and includes: a first vapor chamber having a first chamber and two first openings; and a second vapor chamber disposed on the first vapor chamber and having a second chamber, two bending portions and a middle portion. The two bending portions are inserted into the two first openings respectively to connect the first vapor chamber, such that the second chamber is in communication with the first chamber.
