摘要： The present invention aims to reduce noise derived from an operation sound of a fan while maintaining cooling capacity of the fan. A cooling system includes a fan which is disposed in a chassis in which a CPU which is exemplified as a heating element is housed, one temperature sensor which is disposed in the chassis, another temperature sensor which is disposed at a position which is different from a position of the one temperature sensor, and a fan control unit which drives the fan in a case where one temperature, which is based on a measured value of one temperature sensor, is at least a first threshold value or in a case where another temperature, which is based on a measured value of the other temperature sensor, is at least a second threshold value which is set to a value lower than the first threshold value.

摘要： An electronic apparatus includes: an apparatus chassis including therein an electronic board; a keyboard provided on a top of the apparatus chassis; and a fan device that includes a fan chassis and a blade part. The fan chassis includes a first air intake formed on a bottom surface thereof, a second air intake formed on a top surface thereof, and an air outlet formed on a side surface thereof. The blade part rotates inside the fan chassis. The fan device is arranged between a basal plate and a bottom surface of the keyboard inside the apparatus chassis. The basal plate includes a first inlet at a position overlapping the first air intake. The keyboard includes a second inlet that makes air pass through the keyboard in an up-down direction thereof. The electronic apparatus further includes a first water stop member that separates the first air intake from the electronic board.

摘要： A heat dissipation mechanism is provided. The heat dissipation mechanism includes a heat receiving plate and a heat transport member. The heat receiving plate includes a heat receiving surface surrounded by a recessed portion. The heat receiving surface is to be in contact with a heat transfer region of an electronic component in order to receive heat generated by the electronic component while the recessed portion receives at least one corner of the heat transfer region when viewed from a direction perpendicular to the heat receiving surface. The heat transport member transfers heat away from the heat receiving plate.

摘要： A stacked conductance fin assembly, that is connected to a heatpipe and an exhaust fan of a computing device, includes: a plurality of fins that are partially overlapped and stacked in a linear array along a first axis of the stacked conductance fin assembly. Overlapping regions of the plurality of fins form two parallel structural walls along the first axis. The overlapping regions overlap along a second axis of the stacked conductance fin assembly, the second axis being perpendicular to the first axis. Each of the plurality of fins includes: a main surface that extends along the second axis between two outermost ends of the main surface; two walls that extend along the first axis, each wall extending from each of the outermost ends of the main surface, respectively; and two offset walls that extend along the first axis, each offset wall extending from each wall, respectively.
