Abstract: An electronic apparatus for a solar power system includes a first shell, a waterproof member, and a second shell. The first shell has a surrounding plate, a receiving space formed in the surrounding plate, and at least one clasp portion disposed on an inner side of the surrounding plate. A surrounding notch is formed on the top of the surrounding plate. The waterproof member is filled in the surrounding notch. The second shell has a surrounding protrusion and at least one clasp part disposed on an inner side of the surrounding protrusion. The clasp part snap fits the clasp portion correspondingly to make the surrounding protrusion embedded in the surrounding notch such that the waterproof member is clamped between the surrounding protrusion and the surrounding plate. Thus, waterproof and dustproof of the electronic apparatus are improved.

Abstract: A waterproof, dustproof, breathing bolt includes a bolt body having a hollow shank with a breathing chamber and a cap member fixedly located at the top side of the hollow shank and defining therein an air passage in communication with the breathing chamber and one or a number of openings in communication between the air passage and the surroundings, and a waterproof breathing member made out of a metal material by powder metallurgy and set in between the breathing chamber and the air passage and having micro pores therein of size larger than air molecules but smaller than water molecules. Thus, the waterproof breathing member allows discharge of hot air out of the apparatus in which the waterproof, dustproof, breathing bolt is installed, but prohibits external water from entering the apparatus.

Abstract: A composite photothermal electric generating device includes a thermal insulation housing, a thermal collecting unit, an electric generating module and a solar panel. The thermal insulation housing includes an opening and is formed with a penetrated hole. The thermal collecting unit is disposed in the thermal insulation housing and arranged corresponding to the location of the opening. At least a portion of the thermal collecting unit is arranged corresponding to the location of the penetrated hole. The electric generating module includes a stirling engine and an electric generator. The stirling engine is adhered to the thermal collecting unit via the penetrated hole. The power of the stirling engine is connected to the electric generator. The solar panel is disposed in the opening, covered and in contact with the thermal collecting unit. Accordingly, the photo energy and the thermal energy of daylight are enabled to be converted into electric energy.
