Abstract: A rotary engine with axially directly connected compression and power cylinders is disclosed, which includes a compression cylinder, a power cylinder, an intermediate cylinder wall located between the compression and the power cylinder to serve as a common inner-end wall of the two cylinders, and a combustion chamber unit fixed to a circumferential surface of the intermediate cylinder wall, so that the rotary engine has axially directly connected compression and power cylinders. A compression-side and a power-side rotational valve are separately fitted in two recessed end surfaces of the intermediate cylinder wall. The compression-side and the power-side rotational valve are provided with three L-shaped first and second openings, respectively.

Abstract: A magnetic-force interactive fan includes a base, a plurality of clamp portions, an actuating portion, a main blade, and at least one interactive blade. The actuating portion has a fixed terminal and a moveable terminal; the fixed terminal is connected to one of the clamp portions. The main blade has a free terminal and a connection terminal; the connection terminal is connected to the moveable terminal of the actuating portion and a main magnet is disposed on the free terminal. The interactive blade has a top terminal and a bottom terminal; the bottom terminal is connected to another clamp portion and an interactive magnet is disposed on the top terminal. The main magnet is disposed corresponding to the interactive magnet and the main blade is driven by the actuating portion to swing, thus producing wind by synchronously swinging the main blade and the interactive blade.

Abstract: A micropump and a disposable pump body thereof are disclosed. The micropump includes the pump body and an actuator device. The pump body includes a chamber, an inlet communicating with the chamber, an outlet communicating with the chamber and a covering membrane on top of the chamber. The actuator device includes an actuator and a transmitting post. One of the two ends of the transmitting post connects to the actuator. The other end of the transmitting post abuts against the membrane. Since the pump body is separated from the actuator device, the pump body is disposable and can be replaced after use to avoid cross-infection of disease, particularly useful for medical liquid delivery.

Abstract: A water block is used to be adhered to a heat-generating element and includes a cavity. The cavity has a chamber therein. One side or both sides of the chamber is provided with an inlet pipeline and an outlet pipeline respectively, thereby communicating with the chamber. Further, the chamber is provided therein with a heat-exchanging means for performing a heat-exchanging action with a working fluid. Finally, the top face of the cavity is provided with a membrane. An activating element is adhered on the membrane for driving the membrane to swing up and down, thereby forcing the working fluid within the chamber to circulate in single direction. The activating element is used as a power source, and in addition, the water block can be made much thinner.

Abstract: A water-cooling heat-dissipating system for facilitating a heat-dissipating action with a heat-generating element includes a water block and a heat exchanger. The above-mentioned components are in fluid communication with one another via a plurality of conduits. The water block is attached on the heat-generating element to absorb the heat generated by the heat-generating element. The top surface of the water block is provided with a membrane. The membrane is provided thereon with an activating element, so that the membrane swings up and down at one side thereof to guide the flow of the working fluid. The heat exchanger performs a heat-conducting action with the flowing working fluid, thereby dissipating the heat absorbed by the working fluid to the outside. In this way, the heat-generating element can be kept in a normal range of working temperature.

Abstract: A water-cooling heat-dissipating system for facilitating a heat-dissipating action with a heat-generating element includes a water block, a membrane pump, a water tank and a heat exchanger. The above-mentioned components are in fluid communication with one another via a plurality of conduits. The water block is attached on the heat-generating element to absorb the heat generated by the heat-generating element. The membrane pump generates a thrust to facilitate the working fluid to perform a cooling action. The water tank is used to store additional working fluid. The heat exchanger performs a heat-conducting action with the flowing working fluid, thereby dissipating the heat absorbed by the working fluid to the outside. In this way, the heat-generating element can be kept in a normal range of working temperature.

Abstract: A membrane pump device powered by an activating element includes a chamber body and a second chamber body. The interior of the chamber body is provided with a chamber. Both sides of the chamber body are provided with an inlet pipeline and an outlet pipeline that are in fluid communication with the aforementioned chamber, respectively. A valve is provided on the inner wall face of the chamber, thereby preventing the working fluid from generating a backflow phenomenon. Furthermore, the top surface of the chamber body is provided with a membrane. An activating element abuts on the membrane for driving the membrane to swing up and down, thereby pressing the working fluid within the chamber to circulatively flow in one direction. Finally, the second chamber body is in fluid communication with the chamber body. The interior of the second chamber body is provided with another valve.
