摘要： A fan apparatus may include a frame, a fan, and a drive mechanism. The fan may be supported for rotation relative to the frame and may include a fan shaft and a plurality of blades extending outward from the fan shaft. The drive mechanism may include a driven wheel, a drive shaft, a first drive wheel, a second drive wheel, and a torque-transmission loop. The driven wheel may be mounted on the fan shaft. The drive shaft may be supported for rotation relative to the frame. The first drive wheel may be mounted on the drive shaft. The second drive wheel may be mounted on the drive shaft. The torque-transmission loop may be engaged with the driven wheel and a selected one of the first and second drive wheels.

摘要： A liquid cooling head includes an upper casing, an impeller, a bottom casing and a skived fin cooling plate. The upper casing has an inlet and an outlet, the upper casing is fixed on the bottom casing, and the impeller is arranged between the upper casing and the skived fin cooling plate. In addition, the skived fin cooling plate is fixed on the bottom casing, and the impeller sucks the heat-dissipating liquid from the inlet and drives the heat-dissipating liquid passing through the skived fin cooling plate, upwardly passing through the impeller and then discharged from the outlet.

摘要： A system for controlling the clearance distance between an impeller blade tip of a centrifugal compressor and a radially inner surface of an impeller shroud in a turbine engine. The system comprises a high pressure air source, an air piston mounted between an engine casing and the shroud and adapted to receive high pressure air from the high pressure air source, a mounting arm coupling the shroud and air piston, and a slidable coupling adapted to allow axial movement of the shroud and joining the shroud to an axial member.

摘要： The invention refers to a fan system (10) comprising a fan shroud (14) and a ring fan (12) having a hub (30), a plurality of fan blades (32), and a ring structure (34). The ring structure (34) has a ring member (46) and a flange member (48), the ring member (46) having a hollow cylindrical shape, the flange member (48) extending radially outwardly from the ring member (46). The fan shroud (14) has an annular shroud flange (54), a shroud body (56) and a plurality of shroud guide vanes (58), the shroud flange (54) extending radially outwardly from the shroud body (56) and being disposed along the rotary axis (A) between the flange member (48) and the shroud body (56), the shroud body (56) being disposed about the ring member (46) and having a first body portion (70), a second body portion (72) and a divergent nozzle (74). A recirculation throttle (88) is formed by the shroud body (56) and the ring member (46) at a location where the first and second body portions (70, 72) of the shroud body (56) intersect one another. The divergent nozzle (74) and a trailing end (50) of the ring member (46) cooperate to form a dynamic sealing feature (90).

摘要： A gas turbine engine, with a conical screw integrated compression system, that utilizes at least one conical screw as an intermediary fluid transport device to facilitate the multi-staging of non-axial compressors, such as centrifugal and diagonal compressors, as well as or alternatively to combine non-axial compressors to axial compressors and to the fan. The conical screw in the compression system applies axial flow translation and funnels, as necessary, the exit flow of the impeller, fan or compressor into the next impeller or compressor.

摘要： A wind wheel including a first air plate, a second air plate, and a plurality of blades disposed between the first air plate and the second air plate. The first air plate includes a central part and an air inlet disposed in the central part; each two adjacent blades form an air duct. The plurality of blades each includes an inlet section next to the air inlet, an intermediate section, and an outlet section. The thickness of the intermediate section is greater than the thickness of the inlet section and the thickness of the outlet section.
