    摘要: An air-driven microfluid control device and its method are disclosed. The control device contains an air source, a first inlet, a second inlet, a narrow sector, and an outlet. The air source is connected two the two inlets to produce an airflow. The first inlet connects to the narrow sector, which then connects to the outlet. The air flows through the first inlet and the narrow sector and exits via the outlet. A fluid tunnel connects to the narrows sideways. The second inlet connects to the fluid tunnel so that the air entering the second inlet flows into the fluid tunnel. Through the interaction between the two inlets, pushing and pulling forces can be produced to control the fluid inside the fluid tunnel.

    摘要: A projector having a mechanism for lowering its surface temperature is provided. The projector includes a fan, a side casing, and an air guide. The side casing is placed adjacent to the fan and includes a first section and a second section. The first section includes at least one air inlet, and the second section includes at least on air outlet. The air guide is disposed above the fan and connected to the first section. The air guide is configured to guide high temperature air in the projector. By using the air guide to guide the high temperature air, the air inlet to introduce low temperature air into the projector, and the air out let to exhaust high temperature air, the temperature of a top surface of the projector is lowered.
