Abstract: A band-type fan structure includes a transmission band body and multiple blades. The multiple blades are side by side disposed on the transmission band body along the surface of the transmission band body in parallel to each other. Each two adjacent blades define therebetween a flow way. When the transmission band body is continuously reciprocally moved, the blades are driven by the transmission band body to continuously reciprocally move to disturb the air in the flow ways so as to produce an air volume.

Abstract: A swing fan structure includes a main body and multiple blades. The main body has an upper face and a lower face. The main body also has a long side and a short side. The blades are side by side disposed on the upper face of the main body in parallel to each other. The blades define therebetween a flow way. The blades are drivable by the main body to reciprocally move along the long side to create an air volume. The swing fan structure has a greatly minified volume. Also, the swing fan structure overcomes the shortcoming of unstable operation of the conventional fan caused by deflection of the blades in rotation.

Abstract: A multi-stage solar power device includes a light-permeable base plate, a plurality of light-condensing plates, a heat-conducting tube, at least one gas turbine, a gas inlet tube and a gas outlet tube. The light-condensing plates include a plurality of arcs with different length. The light-condensing plates are spaced from each other and arranged under the light-permeable base plate to define a plurality of light-reflecting chambers. The heat-conducting tube has first and second ends and extends through the light-reflecting chambers. At least one gas turbine is disposed in the heat-conducting tube. The gas inlet tube has first and second sections. The first section protrudes from the light-permeable base plate, and the second section extends through the light-permeable base plate. The gas outlet tube has one end protruding from the light-permeable base plate, as well as an other end extending through the light-permeable base plate.

Abstract: A band-type fan structure includes a transmission band body and multiple blades. The transmission band body has a lengthwise direction and a widthwise direction. The blades are side by side disposed on the transmission band body in parallel to each other and arranged in the lengthwise direction of the transmission band body. Each two adjacent blades define therebetween a flow way. The transmission band body is movable in the lengthwise direction, whereby the blades are driven by the transmission band body to transversely move to create an air volume. The band-type fan structure has a greatly minified volume. Also, the band-type fan structure overcomes the shortcoming of unstable operation of the conventional fan caused by deflection of the blades.

Abstract: A fan module includes a heat transfer unit, a heat radiation unit, and at least one cross-flow fan. The heat radiation unit has an air-in side and an air-out side. The cross-flow fan is located against the heat radiation unit, and includes a frame and a centrifugal fan blade assembly. The frame has an air outlet, a plurality of air inlets, and a plurality of frame sections. The frame sections respectively have a receiving recess therein, and the receiving recesses are communicable with one another to together define a receiving space for receiving the centrifugal fan blade assembly therein. With the above arrangements, the cross-flow fan can create increased air flow volume, the space occupied by the fan module can be reduced, and upgraded heat dissipation performance can be achieved.

Abstract: A thermal module includes a heat radiating unit, a heat transfer unit, and at least one cross-flow fan. The heat radiating unit has an air inlet and an air outlet that communicate with each other. The heat transfer unit has a heat absorbing section attached to a heat source and a heat dissipating section extended from the heat absorbing section to connect to the heat radiating unit. The cross-flow fan is arranged opposite to the heat radiating unit with an air-out side of the cross-flow fan located adjoining to the air inlet of the heat radiating unit. With the above arrangements, the thermal module occupies a largely reduced area while providing largely upgraded heat dissipation effect.

Abstract: A tube-type wind power generator includes an intake tube, an exhaust tube and a wind power generation device. The intake tube has a first end, a second end and an intake air channel, wherein the first end has a plurality of air inlets. A narrow portion is formed between the first and second ends. The exhaust tube surrounds the intake tube and has an opening end and a closed end, wherein the opening end has a plurality of windward openings and a plurality of air-guiding openings. An exhaust channel is defined between the exhaust tube and the intake tube. A gap is defined between the closed end of the exhaust tube and the second end of the intake tube. The wind power generation device has an axial-flow type impeller and a generator, wherein the axial-flow type impeller is disposed at the narrow portion of the intake tube.

Abstract: An intake and exhaust structure includes an outer duct, an inner duct and an air-guiding cover. The outer duct has a first end and a second end. The inner duct has a first end, a second end and an intake air channel. The inner duct is disposed in the outer duct, and a circular air channel is defined between the inner and outer ducts. The air-guiding cover has an inner wall and an air inlet at two ends thereof, wherein the inner wall is coupled with the second end of the inner duct.
