Abstract:
A cooling system includes a first group of fans, a second group of fans, and an air conducting cover. The air conducting cover includes a first partition, a second partition, a third partition. The first partition is connected between the second partition and the third partition to define a first space, a second space and a third space. Wherein the first group of fans directs air flow to enter the first space and the second space, the second group of fans directs air flow to enter the third space.
Abstract:
A container data center includes a container having a raised floor defining a number of vents, a server system including a cabinet supported on the raised floor adjacent to the vents, a cooling device, an adjusting plate movably installed to the cabinet for covering or uncovering the vents, a driving member, a temperature sensor mounted to the cabinet, and a micro control unit (MCU) electrically connected to the driving member and the temperature sensor. The cooling device releases cooling air into the container under the raised floor. The temperature sensor senses the temperature in the cabinet. The MCU receives the sensed temperature and compares the sensed temperature with a preset temperature, to direct the driving member to drive the adjusting plate to move relative to the vents.
Abstract:
An electronic device includes a case having a vent defining a plurality of holes. The electronic device further includes an adjusting plate movably mounted on the case and aligning with the vent, and the adjusting plate defines a plurality of holes. A plurality of vent regions are defined on the vent, at least one hollow region and at least one tangible region are defined on the adjusting plate. The adjusting plate is movable relative to the vent such that the plurality of the holes of the adjusting plate aligns with, or the adjusting plate partially blocks or totally blocks, the plurality of holes of the vent.

Abstract:
A server rack includes a main body, a pair of rails, and a pair of air guiding members. The main body includes two opposite sidewalls, each of which include a first flange defining a number of first through holes and define an air hole. The rails define a channel communicating with the air holes in the main body. Each air guiding member covers the corresponding air hole and includes a second flange that contacts corresponding first flange and defines a number of second through holes. A portion of the second though holes in each second flange and the corresponding first through holes are inserted by fasteners and the other second through holes and the corresponding first through holes without the fasteners inserted are reserved for directing cooling air to the channel via the air guiding members and the air holes.
Abstract:
A common module for a double data rate-synchronous II synchronous dynamic random access memory (DDRII SDRAM) and a DDRIII SDRAM applied in a computer is provided. The common module includes a first bus, a termination circuit card, a first slot, and a second slot. The first bus transmits a plurality of signals. The termination circuit card comprises a plurality of termination resistors. The first slot is disposed on the common module and coupled to the first bus. The DDRII SDRAM is installed in the first slot. The second slot is disposed on the common module and coupled to the first bus. The DDRIII SDRAM or the termination circuit card is installed in the second slot. When the DDRII SDRAM is installed in the first slot, the termination circuit card is installed in the second slot.
Abstract:
A method for detecting and compensating electrode wear of electric discharge machining (EDM) is disclosed, which comprises the steps of: defining a calibration node; calculating a wear length of a tool electrode by an edge-finding algorithm; using the calculated wear length of the tool electrode as a cut compensation for compensating a machining depth of next new tool electrode replacing the previously machined tool electrode; whereas the machining depth is obtained according to the following formula: the machining depth=designed depth of cut+predicted wear of the tool electrode for machining to desire depth−calculated wear length of the previously machined tool electrode+a through hole offset. With the aforesaid method, the wear of an used tool electrode can be detected automatically for compensating the machining depth of an unused tool electrode without ant additional equipment while achieving accurate machining.

Abstract:
An air conducting cover for a server includes a recess portion, a guiding portion, and a connecting portion. The guiding portion upwardly and outwardly extends from an end of the recess portion. The connecting portion horizontally extends from an end of the guiding portion and is attached to the server. The server includes a server motherboard bracket and a server motherboard installed on the server motherboard bracket. The air conducting cover is disposed on the server motherboard bracket and combined with the server motherboard bracket as an airflow channel. The airflow channel is a diverging duct and gradually narrowed from two ends to a middle. Thus, a blowing speed of a cooling air insufflated into the server is accelerated. The air conducting cover can improve heat dissipation efficiency of the server without additional room and will not produce more noise.
Abstract:
A reinforced structural member is disclosed that includes a composite matrix formed of plastics reinforced with wood fibers (or glass fibers) and additives including calcium carbonate and ashes; and a reinforcing element (e.g., aluminum alloy or steel) as skeleton with the composite matrix formed therearound. The structural member has the advantages of being not susceptible to deform due to direct sunlight, and a great increase of structural strength. In one embodiment the reinforcing element has a hollow, axial tube. In another embodiment the structural member is shaped as either a rod or a plate.
