Abstract: A heat dissipation device includes a heat dissipation piece, heat conduction plates, a rod piece and a switch. The heat conduction plates are connected to the heat dissipation piece and spaced apart from and arranged parallel to each other so as to define accommodating spaces. Each heat conduction plate has a free end away from the heat dissipation piece, and the free end has a through hole. The rod piece has a first end and a second end opposite to each other, the rod piece penetrates through the through holes, and the second end has a limitation portion. The switch has a cam portion pivoted to the first end. When the switch is pivoted with respect to the heat conduction plates, the cam portion drives the rod piece to move among the through holes, making the limitation portion to press against or be separated from the heat conduction plates.

Abstract: In a heat dissipating device adapted to a plurality of memory modules, a base surrounds the memory modules and has two long edges parallel to the memory modules, a first short edge and a second short edge. A plurality of heat conducting members of a comb-shaped frame extends from a heat dissipating wall connected to the first short edge to the second short edge. The heat conducting members are arranged side by side to form a plurality of receiving spaces for receiving the memory modules. A cover is pivotally connected to the comb-shaped frame and can rotate with respect to a first axis parallel to the first short edge. A movable portion is fixed with the comb-shaped frame and two resilient wings of the cover push two outmost heat conducting members inwardly, such that the heat conducting members and the memory modules abut against each other tightly.

Abstract: An optical transceiver is provided and connected to a display surface, including a main body, a slider, an elastic element, a movable element, and a circuit board. The main body comprises a base and a cover. A protrusion and a groove are formed on a side of the main body, and the groove extends along a direction toward the protrusion. The circuit board is clamped between the base and the cover and not parallel to the protruding direction of the protrusion. The slider is movably connected to the groove. The elastic element is connected between the slider and the main body. The movable element is connected to the main body and the slider.
