A fan cage is at least adapted to a first fan and a second fan smaller than the first fan. The fan cage includes a cage body and an adjustment member. The cage body defines a first accommodation portion in a size fitting the first fan. The adjustment member is movably disposed on the cage body and switchable between a laid down status and an upright status within the first accommodation portion. When the adjustment member is in the upright status, the adjustment member is upright in the first accommodation portion so that the adjustment member and the cage body together define part of the first accommodation portion as a second accommodation portion in a size fitting the second fan.

According to various embodiments, a wireless charging device can comprise: a first housing, which includes a first surface facing a first direction and a second surface facing a second direction opposite to the first direction, and includes at least one hole; a second housing arranged on the second surface of the first housing in the second direction; a coil unit arranged between the first housing and the second housing and configured to transmit power to an external device; a shielding member arranged adjacent to the coil unit and including at least one hole; and a fan arranged adjacent to the coil unit and configured to rotate.

A bi-directional fan device that is field replaceable within an electronic system is provided. The bi-directional fan device includes a fan unit that cools an electronic system when connected to a power source, and an electrical connector constructed at both ends of the fan unit to electrically connect to the power source.

Apparatus, systems, and methods are disclosed for cooling an electronic device. An example electronic device includes a chassis, a first fan including a first outlet and a second outlet, and a second fan having a third outlet and a fourth outlet. In the example electronic device, the first fan is to exhaust air through the first outlet and the second fan is to exhaust air through the third outlet to create a positive pressure in the chassis. The first fan is to exhaust air through the second outlet to an exterior of the chassis, and the second fan is to exhaust air through the fourth outlet to an exterior of the chassis.

A structure for mounting a cooling fan easily and conveniently and in the correct orientation only includes a chassis and at least one fan module. The chassis has a block, a first nut, and a second nut. The fan module has at least one accessory. The block is mounted on the first nut or the second nut. When the block is fixed on the first nut, the fan module can only be placed and installed so as to blow air into the chassis, and when the block is fixed on the second nut, the fan module can only be installed so as to extract air out of the chassis, thereby ensuring the correct mode of operation. An electronic device and a server using the structure is also disclosed.

A wavelength conversion device includes a rotating device, a substrate rotated by the rotating device, a wavelength conversion element, and a first cooling device including, on an inside, a space in which working fluid is encapsulated, the first cooling device cooling the wavelength conversion element. The first cooling device is disposed in a position corresponding to the wavelength conversion element. The space extends from an outer edge side of the substrate to a rotation axis side. The first cooling device includes an evaporator and a condenser which are provided in the space. The evaporator includes a liquid retaining part configured to retain the working fluid in a liquid phase. The liquid retaining part is provided at the outer edge side in the space and disposed in the position corresponding to the wavelength conversion element.

An internal component and external interface arrangement for a cylindrical compact computing system is described that includes at least a structural heat sink having triangular shape disposed within a cylindrical volume defined by a cylindrical housing. A computing engine having a generally triangular shape is described having internal components that include a graphics processing unit (GPU) board, a central processing unit (CPU) board, an input/output (I/O) interface board, an interconnect board, and a power supply unit (PSU).

A fan tray, for a fan module of a network device chassis, may include an inner assembly that includes an inner cassette, one or more fans connected to the inner cassette, a first latch connected to the inner cassette and configured to removably connect to an outer assembly of the fan tray, and a fan controller connected to the inner cassette and configured to control operation of the one or more fans. The outer assembly may be configured to receive and retain the inner assembly, and may include an outer cassette with one or more openings configured to communicate with the one or more fans, a second latch connected to the outer cassette and configured to removably connect to a rear portion of the network device chassis, and an adaptor connected to the outer cassette and configured to connect and provide power to the fan controller.

A measuring apparatus including at least one housing part including a shaped body made from a foam material.

An electronic apparatus includes: a chassis; a substrate housed in the chassis and with a processing device mounted thereon; a speaker device housed in the chassis and having a speaker unit and a speaker box; and a cooling device housed in the chassis and used to cool the processing device. The substrate is placed vertically along the vertical direction of the chassis. The cooling device includes: a fan having air intake ports provided on upper and lower surfaces, exhaust ports provided on side surfaces, and an impeller, and being placed horizontally in the chassis with a rotating shaft of the impeller placed along the vertical direction of the chassis; a fin placed facing the exhaust port of the fan and placed horizontally in the chassis; and a heat pipe with a first end connected to the processing device and a second end connected to the fin.
