Abstract: A chassis structure with interface card bracket is described, which uses a bracket to assemble an interface card in an accommodation space within a chassis. The bracket includes a carrying member and an operating member that are pivoted to each other, and the interface card is fixed on the carrying member. The chassis includes a guide portion disposed therein. As the bracket moves into the accommodation space, the carrying member and the operating member are pivoted with respect to each other upon being guided by the guide portion to form an appropriate included angle there-between, so as to avoid barriers around the accommodation space, thereby assembling the interface card into the accommodation space successfully.

Abstract: A chassis structure with interface card bracket is described, which uses a bracket to assemble an interface card in an accommodation space within a chassis. The bracket includes a carrying member and an operating member that are pivoted to each other, and the interface card is fixed on the carrying member. The chassis includes a guide portion disposed therein. As the bracket moves into the accommodation space, the carrying member and the operating member are pivoted with respect to each other upon being guided by the guide portion to form an appropriate included angle there-between, so as to avoid barriers around the accommodation space, thereby assembling the interface card into the accommodation space successfully.

Abstract: A heat-dissipating fan fixing device used for accommodating and fixing a fan and mounted on a case is provided, which includes a frame, a plurality of hooks and an elastic buckle piece. The frame has a first end and a second end being opposite to each other. Between the first end and the second end, an accommodating space through the frame is formed for accommodating and fixing the fan. The hooks extend from one side edge of the first end, and the elastic buckle pieces are formed by bending along another side wall of the first end. Thus, when the frame is joined with the case, firstly, each hook catches the case, and then, the elastic buckle piece is embedded into the case, thereby mounting the fixing device with the fan on the case.

Abstract: A fixing device is disposed in a case of a computer for fixing at least one interface card. The interface card is installed to a circuit board through an installation path. The fixing device includes a plate and a pressing element. The plate is disposed in the case, or is part of the case. The pressing element having at least one groove is movably disposed on the plate to be moved between a fixing position and an installing position. When the pressing element is moved to the fixing position, the pressing element presses the interface card. When the pressing element is moved to the installing position, the groove overlaps the installation path for the interface card to pass through.

Abstract: A heat dissipation air duct is provided. The air duct is fixed inside a computer case, and covers a plurality of high heat-generating elements on a mainboard. The air duct includes a main air duct and an auxiliary air duct. The main air duct isolates a first air duct area inside the computer case, and an air inlet is formed in a side of the air duct area. The auxiliary air duct is fixed on the bottom of the main air duct, and is accommodated in the first air duct area, so as to further isolate a second air duct area in communication with the air inlet it the first air duct area. One of the pluralities of high-generating elements is covered by the auxiliary air duct, and is accommodated in the second air duct area.
