Abstract: A cabinet server includes a power module, at least one direct-current device, at least one alternating-current device, a direct-current power module, and an alternating-current power module. When the direct-current power module is inserted into the power module, the direct-current power module is connected to the at least one direct-current device by using the power module, and the direct-current power module is configured to provide a first direct-current voltage to the at least one direct-current device. When the alternating-current power module is inserted into the power module, the alternating-current power module is connected to the at least one alternating-current device by using the power module, and the alternating-current power module is configured to provide a second alternating-current voltage to the at least one alternating-current device.

Abstract: A liquid leakage detection apparatus configured for liquid leakage detection of a liquid cooling apparatus of a printed circuit board, wherein the liquid leakage detection apparatus includes a sleeve, a first liquid cooling pipe, a liquid cooling plate, flow guiding apparatuses, and a liquid leakage detection circuit. The sleeve wraps the first liquid cooling pipe, the first liquid cooling pipe is coupled to the liquid cooling plate, the liquid cooling plate and the first liquid cooling pipe are configured to dissipate heat for an electronic element using a filled coolant, the flow guiding apparatuses are coupled to an edge of the liquid cooling plate, the other ends of the flow guiding apparatuses are coupled to the liquid leakage detection circuit.

Abstract: The present invention discloses a method and an apparatus for cultivating and consuming fresh Spirulina at home. The method comprises species selection of Spirulina for cultivation at home, cultivation environment and apparatus conditions, cultivation and maintenance of Spirulina, collection of fresh Spirulina, consumption and storage of fresh Spirulina. The invention changes the situations that Spirulina are only produced in plants and the finished products of Spirulina are bought in stores or hospitals. The invention not only enables the nutrients of Spirulina to be stored and utilized much completely, but also comprehensively utilizes this original biological resource and characteristics of Spirulina (such as absorption of carbon dioxide, release of fresh oxygen and production of high-protein nutrient source) and thus develops and popularizes much quickly the edible Spirulina to meet the needs of the public to health foods.
