Abstract: A smart cooling system is mainly applied to an electronic equipment room, in which an extended encircled space is constituted by combining a front extension frame and a rear extension frame with a cabinet, respectively, followed by fitting a cooling apparatus to a plurality of cabinets, to which a pipeline having a path in one single flowing direction is connected in turn. An appropriate amount of air conditioning is guided to a position where it is needed directly and definitely by means of the determination, via temperature sensing units provided within the cabinets, of the demand for air conditioning and the position where the demand comes from. Thereby, not only the cost of construction of air conditioning is reduced significantly, but also the effects of energy conservation and precise cooling are achieved.

Abstract: A cabinet air-conditioning guiding mechanism, a front frame and a rear frame are provided to connect to the cabinet to form an enclosed interior, cold air is guided inwards and hot air is guided outwards directly to form an unidirectional flow mechanism directly applied to the interior of the cabinet, to achieve the purpose of rapid cooling, so that heat exchange efficiency and efficacy of air-conditioning management may be improved, and energy may be saved, space of electronic equipment room may be effectively used and cost of setting air-conditioning may be reduced.

Abstract: A rack assembly includes at least four columns, a top frame module and a bottom frame module. The at least four columns are connected between the top and bottom frame modules. The rack assembly can be easily disassembled for reducing the room required in transportation, and the rack assembly can be easily assembled in offices.

Abstract: A rack includes a frame, two locking portions and a power unit. The frame includes multiple links and the two locking portions are located on two correspondent links or formed on extension portions of the links. The power unit is located corresponding to one of the locking portions and located in the frame, or the power unit is parallel to one of the locking portions and located in the frame. The power unit has at least one power cable and multiple power modules which are respectively connected to one side of the power unit and exposed from the power unit. Each of the power modules is connected to one of the at least one power cable. The two sides of the electronic device are fixed to the locking portions. The power cable and the transmission line of the electronic device are connected to the power unit.
