An electronic device includes an electronic component and a heat dissipating casing configured to dissipate heat from the electronic component. The casing includes top and bottom sides of the heat dissipating casing forming a sealed chamber, and a pore structure formed within the sealed chamber. The sealed chamber is configured to receive a working medium and the pore structure is configured to absorb at least a portion of the working medium, whereby the heat generated from the electronic component is dissipated by a phase change of the working medium.

An exemplary method for manufacturing a fan rotor includes the following steps. First, a discoid-shaped metal sheet is provided. Second, the metal sheet is stamped such that the stamped metal sheet includes a hub at a middle thereof, a blade-portion spaced from and surrounding the hub, and supporting bars interconnecting the hub and the blade-portion. The blade-portion includes outer peripheral blades adjacent to each other. Third, a free end of each blade is curled up by force applied along a direction substantially perpendicular to a plane of the blade-portion. Finally, each blade is bent downward about an axis coinciding with a portion of one side of the blade that connects with an inner periphery of the blade-portion.

A heat dissipation device includes a base and a fastener. The fastener includes a neck portion, a head portion formed at one end of the neck portion, and an engaging portion formed at another opposite end of the neck portion. The base defines a receiving portion through the base. The receiving portion includes an inserting hole and a mounting hole communicating with the inserting hole. The engaging portion extends through the inserting hole from a top of the base to make the neck portion enter the inserting hole. The neck portion is then crushed into the mounting hole from the inserting hole. The engaging portion abuts the bottom side of the base at a periphery of the mounting hole. The head portion abuts the top side of the base at the periphery of the mounting hole.
