摘要： A heat dissipation net disposed on a base plate of a vapor chamber unit includes a base net portion and conduction units formed on the base net portion. Each conduction unit has a protruding area, a recessed area, and a curved section formed between the protruding area and the recessed area. When the heat dissipation net is disposed on the base plate, the existence of the recessed area and the curved section prevents the base net portion from being unduly pressed and stuck to the base plate to thereby improve a capillary action of the heat dissipation net. A space formed between each protruding area and the base plate facilitates the quick conduction of vaporized working fluid of the vapor chamber unit. Thus, the entire heat dissipation efficiency is increased.
