摘要： A blower includes a first tower and a second tower spaced apart from each other each having discharge ports that face each other. A gate is movably installed in at least one of the first tower or the second tower to protrude into and out of the space between the first and second towers to change a flow of air discharged out of the discharge ports. A guide motor may be configured to move the gate. The discharge ports may be provided at a rear side of the space to discharge air toward a front of the space, while the gate may be moved to cover the front side of the space to guide air upward.

摘要： A strong cooling direct air-cooled condenser radiating unit and an air-cooled island are provided, comprises a cooling wall, an air supply device and a flow guide device located in the cooling wall. The air supply device comprises a unit air supply channel, an air supply ring, and an air collecting cavity. The air supply ring is located at the lower part of the cooling wall and is an annular body with a cavity. An annular slit outlet is formed in the lower part of the air supply ring. The upper part of the air collecting cavity communicates with the air supply ring. A separating plate is provided in the unit air supply channel and divides the unit air supply channel into upper and lower air flues. The upper air flue communicates with the cavity of the air supply ring. The lower air flue communicates with the air collecting cavity.

摘要： An augmentation amplifier is provided for aspirating gas flow from a surrounding medium. The amplifier connects at an inlet to a pressurized gas source and at an outlet to a gas receiver. Ambient gas from the medium supplements source provided compressed gas. The amplifier includes a Venturi conduit including a throat, an external cavity and a diffusion chamber. The conduit receives and flows pressurized gas from the inlet to the throat. The cavity receives ambient gas from the medium. The chamber expands and accelerates the pressurized gas from the throat to entrain the ambient gas via aspiration. The accelerated and ambient gases combine into an exhaust gas to the outlet.

摘要： The present disclosure relates to a bladeless fan, which includes a housing and a power device, wherein the power device communicates with a fluid passage and a negative pressure passage disposed in the housing respectively; the fluid passage communicates with the outside through a plurality of exhaust ports, and the negative pressure communicates with the outside through a plurality of suction ports; a middle region inside the fluid passage is provided with a spoiler device so that a path along which the fluid passes through the spoiler device is larger than a path along which the fluid passes around the corresponding inner wall, thereby generating a pressure difference. The present disclosure enables a higher-speed flow of the fluid inside the fluid passage through pressure difference without adding extra power, and generates a faster air speed in a more energy-saving way, thereby achieving a remarkable effect of cooling.

摘要： Systems and methods are provided for a bladeless radiator cooling fan. In one example, a system may include a plurality of bladeless entrainment discs surrounded by a shroud, each bladeless entrainment disc including a hollow central opening that enables unrestricted ambient airflow through the cooling fan, and a source fan for providing airflow to the bladeless entrainment that is encased by a housing. In this way, airflow through the bladeless radiator cooling fan may be increased, decreasing powered fan usage and decreasing fan noise.
