Abstract: A thermal module includes a shell, a plurality of fans assembled in the shell, and a plurality of louvers. The shell defines a plurality of openings corresponding to the fans. Each louver includes a frame coupled to one of the vents and a plurality of louver boards. A side edge of each louver board extends outward forming a shaft rotatably coupled to two opposite sides of the frame. The gravity center of the frame is configured adjacent to an end of the frame, which is away from the shaft.

Abstract: A computer case includes two opposite boards, two brackets, two elastic elements, and two latching elements. Each board has a recessed portion with a resisting surface. The two brackets are rotatably connected to the two resisting surfaces respectively. Each bracket defines a pinhole away from the resisting surface. Each elastic element is positioned between a corresponding resisting surface and a corresponding bracket to supply elastic force between the corresponding resisting surface and the corresponding bracket. The two latching elements are slidably mounted on the two opposite boards. Each latching element includes a latching portion. When the brackets contact the resisting surfaces, the latching portions are received in the pinholes to latch the brackets.
