Claim 0:
1. A slim heat-dissipation module, comprising:
a first plate, comprising a plurality of metal pillars, a first inner surface and a second inner surface, wherein the metal pillars are formed on the first inner surface;
a second plate, comprising a third inner surface and a fourth inner surface, wherein the first plate is combined with the second plate, a first type chamber is formed between the first inner surface and the third inner surface, a second type chamber is formed between the second inner surface and the fourth inner surface, and the first type chamber is not communicated with the second type chamber;
a first porous structure, disposed in the first type chamber, wherein the first porous structure contacts the third inner surface, and the first porous structure is not in contact with the first inner surface;
a second porous structure, disposed in the second type chamber, wherein the second porous structure contacts the second inner surface and the fourth inner surface, wherein the second porous structure is a sheet-shaped structure, a circulation groove is formed on the second porous structure, and the circulation groove is a through opening;
a first fluid, disposed in the first type chamber; and
a second fluid, disposed in the second type chamber,
wherein a first circulation path is defined between the second inner surface and a top surface of the second porous structure, two second circulation paths are formed in the second porous structure, and the two second circulation paths are located on two lateral sides of the circulation groove,
wherein when the second fluid is in a gaseous state, most of the second fluid travels in the first circulation path, and when the second fluid is in a liquid state, most of the second fluid travels in the second circulation path,
wherein the first circulation path overlaps at least a portion of the second circulation path.
