Abstract: An air duct includes two opposite sidewalls, a top wall connected between top sides of the sidewalls, and a blocking member detachably mounted to an outer surface of one of the sidewalls.

Abstract: An electronic device includes a motherboard. A first heat sink and a second heat sink are set on the motherboard. A number of memories are set on the motherboard and located at two sides of the first heat sink. An air duct is located between the first heat sink and the second heat sink. The air duct includes a main body and two air baffles. The main body includes a top board and two side boards extending from opposite sides of the top board. The top board and the two side boards cooperatively define an airflow channel. The airflow channel includes an air intake facing the first heat sink, and an air outlet facing the second heat sink. Each side board defines an opening. Each air baffle is pivotably mounted to the corresponding side board and adjacent to the corresponding opening.

Abstract: A device for fixing two fans includes a chassis, a limiting member mounted in the chassis, and a blocking member. A receiving space is bounded by the chassis and by the limiting member. The blocking member is sandwiched between the fans, and includes two angled plates which may concertina towards or away from each other as the fans are repositioned to seal the space between the fans.

Abstract: An electronic device includes an enclosure, an expansion card installed inside the enclosure, and a bracket. The enclosure includes a sidewall defining a through slot, and a supporting plate extending outwards from an upper portion of the sidewall. The bracket includes a fixing plate, and a stop plate. The fixing plate is supported on and fixed to a top of the supporting plate. The stop plate extends down from the fixing plate to fix an end of the expansion card. The stop plate engages with an inner side of the sidewall and covers the through slot. A number of vents is defined in the stop plate in communication with the through slot so that hot air in the enclosure may be dissipated by a cooling airflow through the vents and the through slot.

Abstract: An enclosure includes a main body defining an opening, and a venting apparatus. The venting apparatus includes a first body defining a number of first vents, and a second body defining a number of second vents. The first body is fixed to the main body to cover the opening. The second body is pivotably attached to an outer surface of the first body. The second body may be rotated relative to the first body to partly overlap the first vents with the second vents to adjust the rate or volume of airflow permitted through a heat-generating device.

Abstract: A carrier includes a main bracket. The main bracket includes a first mounting member and a second mounting member. The first mounting member includes a first sidewall and a first front wall. The second mounting member includes a second sidewall and a second front wall. The first front wall is telescopically extensible relative to the second front wall. A retaining width between the first sidewall and the second sidewall is adjustable in order to couple to various size data storage devices.

Abstract: A mounting apparatus for a data storage device includes a bracket, two slide boards, and a number of fasteners. The data storage device includes opposite sidewalls each defining a number of fixing holes. The bracket includes two mounting arms each defining a number of through holes. The slide boards are slidably mounted to the mounting arms before fixed to the bracket via the plurality of fasteners. The data storage device and the slide boards are capable of adjusting positions relative to each other such that at least one set of one of the fixing holes, one of the through holes, and one of the mounting holes, corresponding to one of the sidewalls, are aligned with each other. One of the plurality of fasteners fastens the corresponding mounting arm and slide board to the corresponding sidewall via extending through the set of aligning holes.

Abstract: An air conduction device includes main body defining a first passage through which airflow passes, and two adjusting members. A top of the main body defines a cutout communicating with the first passage. The cutout includes two opposite slanted sidewalls, and each slanted sidewall defines a plurality of slots aligned in a line along a slanted direction of the slanted sidewall. An elastic hook extends from each adjusting member. The adjusting members are accommodated in the cutout, with the elastic hooks selectively engaged in one of the corresponding slots.
