Abstract: A heat dissipation device including a mounting seat, a fan hung on the mounting seat and a frame connected with the fan is provided. The fan has an air outlet and an air inlet opposite to the air outlet, the air inlet is disposed facing to the mounting seat, the frame is arranged surrounding the air inlet and clamped between the mounting seat and the air inlet. Thereby, a back flowing hot airflow is prevented from being sucked into the air inlet.

Abstract: A conveying apparatus with a lift mechanism includes a carrier, a holder, and a lift handle. The holder is pivoted to the carrier and swings between an operating angle and a maintenance angle. A first arm of the lift handle has an acting end, a resistance end, and a second pivot disposed between the acting end and the resistance end and pivoted to the holder. The first arm further has a protruding length protruding from the bottom side of the holder. When the first arm rotates around the second pivot, the resistance end protrudes the protruding length from the bottom side to rest against the carrier and the holder is lifted to the maintenance angle using the protruding length. Therefore, the storage devices in the holder, originally difficult to be maintained, can be lifted and maintained simply and quickly.

Abstract: A computer device includes a holding structure, a motherboard module and a cover plate. The holding structure includes a holder and a frame. The holder includes a supporting face and an end edge. The frame is connected to the supporting face and arranged adjacent to the end edge. The frame includes an opening and a top bar. The motherboard module, including I/O ports disposed in the opening, is installed on the supporting face. The cover plate covers the opening, a bottom portion of the cover plate is detachably connected to the end edge with a positioning structure, a top portion of the cover plate is detachably connected to the top bar with a fastening structure, the cover plate includes through slots, and the I/O ports are inserted through or disposed corresponding to the through slots respectively, so that the computer device facilitates easy and flexible assembly.

Abstract: A server cabinet drawer structure includes a carrying tray, a movably swappable frame and a lifting element. The movably swappable frame is carried by the carrying tray, and a side of the movably swappable frame is pivotally connected to the carrying tray by a pivot. The lifting element is provided for lifting the movably swappable frame away from the carrying tray and connected to the carrying tray and the movably swappable frame, so as to facilitate users to swap a data storage unit in the movably swappable frame.

Abstract: A storage device slow descent structure includes a chassis (100) and an elevating element (200). The chassis (100) includes a front load plate (110), a rear load plate (120), and a sliding unit (130). An end portion (132) of the sliding unit (130) is slidably connected to one side of the rear load plate (120). The elevating element (200) includes two linkages (210) respectively having a front end (212) and a rear end (214). The two linkages (210) are respectively connected to the front load plate (110) and the end portion (132). The rear end (214) is pivotally connected to the slide member (134). The front end (212) is pivotally connected to the front load plate (110). A self-weight of the front load plate (110) drives the rear end (214) to slide from one end to the other end of the slide member (134).

Abstract: A combining assembly for a fan fixing base is fixed in a housing and includes a fan module and a frame plate. The fan module includes a fixing base, a heat-dissipating fan disposed in the fixing base, and a plurality of locking elements. The heat-dissipating fan is provided with a plurality of locking holes. The fixing base has a plurality of through-holes. The locking elements are disposed through the through-holes to be connected into the locking holes, thereby fixing the heat-dissipating fan into the fixing base. The frame plate is provided with a plurality of positioning troughs to correspond to the locking elements. The fan module is engaged in the positioning troughs via the locking elements.

Abstract: A fixing assembly for a fan module is combined in a housing and includes at least one fixing base and at least one bottom pad. The fixing base has an accommodating space and a plurality of positioning portions in the accommodating space. The positioning portions are provided in pairs and symmetrical to each other. The locations of the positioning portions are designed for positioning various sizes of heat-dissipating fans. The bottom pad is configured to support the bottom of the fixing base. By this structure, various sizes of fan modules can be positioned in the housing.

Abstract: A return air blocking device for a fan-based heat dissipation mechanism includes a plurality of rotatable hinged plates provided in a heat-dissipation mechanism having a plurality of fans. The rotatable hinged plates are lifted open or shut due to the presence or absence of airflow kinetic energy. When some of the fans fail, the corresponding rotatable hinged plates are shut to prevent hot exhaust from returning to and being detained in the heat dissipation mechanism.
