20120288112 | METHOD AND CONTROLLER FOR CONTROLLING NOISE OF ROTATING DEVICE - A method for controlling noise of a rotating device includes: obtaining a sound wave signal of noise generated by the rotating device, where the sound wave signal is fed back by a reference sensor; obtaining rotational speed information of the rotating device; and searching a predefined function mapping table according to the rotational speed information to obtain transfer functions; generating a sound emitting command according to the transfer functions and the sound wave signal; and sending the sound emitting command to a secondary source emitting device, so that the secondary source emitting device emits a secondary sound wave, where the secondary sound wave is used to suppress the noise generated by the rotating device. | 11-15-2012 |
20130082584 | PANEL FOR VENTILATION AND NOISE REDUCTION AND MANUFACTURING METHOD - A panel for ventilation and noise reduction and its manufacturing method are disclosed A left side and a right side of the panel each include one or a plurality of ventilation holes, and a sound insulation board for sound insulation is set near each ventilation hole along an inner side of the panel, so that at least certain sound from the inner of the electronic device needs to bypass the board to pass through the ventilation holes; and the ventilation hole on the left side and the right side of the panel are opened in a staggered position, so that when the panel is placed side by side with another panel, air exhausted from a ventilation hole at an adjacent side of the panel does not form strong face-to-face blowing interference with air exhausted from a ventilation hole at an adjacent side of another panel. | 04-04-2013 |
20130324025 | FLOW-GUIDING APPARATUS AND ELECTRONIC DEVICE INCLUDING THE FLOW-GUIDING APPARATUS - The present invention is applicable to the technical field of heat-radiation structures and discloses a flow-guiding apparatus and an electronic device including the flow-guiding apparatus. The flow-guiding apparatus includes a support and flow-guiding members for guiding an air flow generated by an axial fan to a directed area, where the flow-guiding members are connected to the support, at least two flow-guiding members are arranged and are located on both sides of a hub of the axial fan or around the hub of the axial fan, and the flow-guiding members tilt toward the hub of the axial fan along an air-blowing direction of the axial fan. The electronic device includes a chassis, where the chassis is provided with an air vent, an axial fan is arranged at the air vent, and an air outlet of the axial fan is arranged with a flow-guiding apparatus mentioned above. | 12-05-2013 |
20130342987 | Method, Apparatus, and System for Dissipating Heat of Memory with Liquid Cooling - An apparatus can be used to dissipate heat from a memory with liquid cooling. A liquid-cooling block is disposed on a main board such that the liquid-cooling block is adjacent to a memory slot. The liquid-cooling block includes a metal block, metal spring leaves fixed on two sides of the metal block, and a liquid channel that penetrates through the metal block. The metal spring leaves are configured to contact a memory bank in the memory slot and conduct heat that is generated during operation of the memory bank to the metal block. A liquid inlet pipe and a liquid outlet pipe are installed on the main board and located at two ends of the liquid-cooling block in a manner such that cooling liquid can enter the liquid-cooling block via the liquid inlet pipe and exit the liquid-cooling block via the outlet pipe to form a cooling liquid loop. | 12-26-2013 |
20140069735 | VENTILATION DENOISING DEVICE AND VENTILATION DENOISING SYSTEM - A ventilation denoising device that includes at least one ventilation module disposed with at least two air ducts inside, the air ducts are communicated end-to-end to form a circuitous air duct. The ventilation module is provided with a first ventilation opening communicated with one end of the air duct, and a second ventilation opening communicated with the other end of the air duct. Also disclosed is a ventilation denoising system equipped with the above mentioned ventilation denoising device. The ventilation denoising device can be installed outside equipments, such as a machine cabinet, as ventilation means thereof, and also reduce the noise generated during the equipment operation. | 03-13-2014 |
20150017828 | Linkage Apparatus for Plugging PCB Board - A linkage apparatus is provided. The linkage apparatus is disposed between a bottom plate and a carrier plate, and the linkage apparatus includes a drag link and an āLā shape swing link. The drag link is rotatably connected to an end of the āLā shape swing link, and the drag link and the bottom plate are connected to a fixing pin by using a horizontal guide groove; a corner in the middle of the swing link is rotatably connected to the bottom plate, and another end is fastened to the carrier plate; another fixing pin connects the bottom plate and the carrier plate. The swing link is driven by the drag link, so that the carrier plate can be driven to vertically move. Therefore, hot plugging of a peripheral component interconnect (PCI) express card fastened on the carrier plate and plugging of another printed circuit board (PCB) that requires two-dimensional plugging can be implemented without interrupting a power supply. | 01-15-2015 |
20150079893 | Panel for Ventilation and Noise Reduction and Manufacturing Method - A panel for ventilation and noise reduction and its manufacturing method are disclosed. A left side and a right side of the panel each include one or a plurality of ventilation holes, and a sound insulation board for sound insulation is set near each ventilation hole along an inner side of the panel, so that at least certain sound from the inner of the electronic device needs to bypass the board to pass through the ventilation holes; and the ventilation hole on the left side and the right side of the panel are opened in a staggered position, so that when the panel is placed side by side with another panel, air exhausted from a ventilation hole at an adjacent side of the panel does not form strong face-to-face blowing interference with air exhausted from a ventilation hole at an adjacent side of another panel. | 03-19-2015 |
