Abstract: A solar energy device (100) for an electronic device includes a solar energy collecting component (10) and a lens module (20). The solar energy collecting component has a first surface (105) and a second surface. The lens module is rotatably mounted relative to the solar energy collecting component.

Abstract: An exemplary heat sink apparatus (10) includes a base (12) and a number of fins (14) extending from an upper external first surface (124) of the base. The base defines a sealed cavity (122) therein. Operating fluid (18) is filled in the cavity. The operating fluid is liquid form. In use, heat produced by a heat source is transferred to the base. Then, the liquid operating fluid in the base absorbs the heat and is vaporized. The vaporized operating fluid is diffused to an upper inner wall (126) of the base and releases the heat, thereby being transformed back into liquid form. The fins transfer the heat to the ambient environment. The heat sink apparatus can dissipate the heat produced by the heat source to the ambient environment quickly and uniformly by adopting the operating fluid. Thus, the thermal operating efficiency and effect of the heat sink apparatus are enhanced.

Abstract: A heat pipe (20) includes a pipe (21), a wick (22) formed on an inner wall (23) of the pipe, and a working fluid (not shown) sealed in the pipe and soaked in the wick. The wick is formed by sintering nano-size metal powder disposed inside the pipe. First through holes (25) are defined in the wick in an evaporator section (20a) of the heat pipe. A central one of the first through holes is aligned along an axis 20c of the heat pipe, and other first through holes are parallel to the axis 20c. A second through hole (26) is defined in the wick in a condenser section (20b) of the heat pipe. The second through hole communicates with the first through holes, whereby the working fluid flows through the first and second through holes. These characteristics give the wick low thermal resistance, a high evaporator surface area, and high capillary force.
