Abstract

A water-cooling radiator unit and a water-cooling module using same are disclosed. The water-cooling radiator unit includes a main body divided into a first section, a second section and a transit zone, which are fluidly communicable with one another. The first section has a first flow passage system and an inlet formed thereon, the second section has a second flow passage system and an outlet formed thereon. The main body is internally filled with a cooling fluid, and the transit zone has a pump mounted therein. The water-cooling radiator unit can be fluidly connected to a water block via two tubes to form a water-cooling module. The pump drives the cooling fluid to circulate in the main body and between the water-cooling radiator unit and the water block, enabling the water-cooling module to provide upgraded heat-dissipation performance while the water block has a reduced volume.

First claim

What is claimed is:

1. A water-cooling radiator unit, comprising:
a main body including a first section having a first flow passage system formed thereon, a second section having a second flow passage system formed thereon, and a transit zone located between the first and the second section and fluidly communicable with the first and the second flow passage system; the first section being provided with an inlet, the second section being provided with an outlet, and the transit zone being formed with a plurality of first apertures fluidly communicable with the first flow passage system on the first section, a water-guiding opening formed on a bottom of the transit zone and fluidly communicable with the first apertures via a bottom passage, and a plurality of second apertures fluidly communicable with the second flow passage system on the second section; and the main body being internally filled with a cooling fluid;
a pump being mounted in the transit zone and including a plurality of blades for driving the cooling fluid filled in the main body to circulate in the main body; and
a partitioning section for defining and separating the first and the second section from each other; the first flow passage system including a plurality of fluidly communicable first transverse flow passages and first longitudinal flow passages.

2. The water-cooling radiator unit as claimed in claim 1 , wherein the first transverse flow passages being located adjacent to one side of the partitioning section; the bottom passage being located below the bottom of the transit zone, and the first apertures radially penetrating wall portions of the transit zone located adjacent to the first section and bringing the first transverse flow passages and the first longitudinal flow passages to be fluidly communicable with the bottom passage; the second flow passage system including a plurality of fluidly communicable second transverse flow passages and second longitudinal flow passages, and the second transverse flow passages being located adjacent to another side of the partitioning section and fluidly communicable with the second apertures; the second apertures radially penetrating wall portions of the transit zone located adjacent to the second section and bringing the transit zone to be fluidly communicable with the second flow passage system; the first longitudinal flow passages being spaced from one another with a plurality of radiating fins formed between any two adjacent first longitudinal flow passages; and the second longitudinal flow passages being spaced from one another with a plurality of radiating fins formed between any two adjacent second longitudinal flow passages.

3. The water-cooling radiator unit as claimed in claim 1 , wherein the transit zone further includes a first reservoir and a second reservoir formed in a wall of the transit zone; the first reservoir being fluidly communicable with the first flow passage system and the first apertures; and the second reservoir being fluidly communicable with the second flow passage system and the second apertures.

4. The water-cooling radiator unit as claimed in claim 1 , wherein the first section further includes a first water chamber, which is fluidly communicable with the first flow passage system, and the second section further includes a second water chamber, which is fluidly communicable with the second flow passage system.
