Abstract: The present disclosure relates to a centrifugal fan and a method for manufacturing the same. The centrifugal fan can easily implement a three-dimensional blade by including a main plate, a blade, and a shroud that injection-molded as one body, thereby reducing the weight of the centrifugal fan and improving the operating efficiency. In addition, since assembly processes such as fastening or welding are unnecessary when manufacturing the blade, the defect rate of the blade can be reduced and the fluidity performance can be prevented from deteriorating due to traces of welded areas.

Abstract: A machine that includes a centrifugal impeller and a diffuser. The impeller has two rows of impeller blades. A first row accelerates the flow away from the axis of rotation, and discharges the flow in an outward radial direction to a second row of impeller blades. The second row first accelerates the flow toward the axis of rotation in an inward radial direction, and then accelerates the flow in the first axial direction. The diffuser has two rows of diffuser blades. A first row of diffuser blades first accelerates the flow in the first axial direction, and then accelerates the flow toward the axis of rotation. The second row of diffuser blades first accelerates the flow away from the axis of rotation, then accelerates the flow in the first axial direction, and then discharges the flow from the diffuser in the first axial direction.

Abstract: A centrifugal fan is disclosed and includes a housing, a fan wheel, a first throat portion and a second throat portion. The housing includes a lower cover connected to an upper cover through a peripheral wall to form an accommodation space and an outlet. The upper cover includes an inlet communicated with the outlet. The fan wheel is disposed on the lower cover and accommodated in the accommodation space. The fan wheel is rotated along a rotation direction. The first throat portion is disposed adjacent to a lateral end of the outlet and protrudes from the peripheral wall toward the accommodation space. The second throat portion is disposed adjacent to another lateral end of the outlet, and protrudes from the peripheral wall toward the accommodation space. When the fan wheel is rotated along the rotational direction, an airflow is guided from the first throat portion to the second throat portion.

Abstract: A compressor includes a drive motor and a wind wheel, wherein the drive motor includes a casing and a rotor, the rotor being rotatably arranged within the casing; the wind wheel is mounted at a first axial end of the rotor. A thrust disc is also provided at the first axial end of the rotor. An axial bearing assembly is arranged between the thrust disc and the wind wheel, and the axial bearing assembly is arranged fixedly with respect to the casing. A first air gap is formed between a first end of the axial bearing assembly and the wind wheel, and a second air gap is formed between a second end of the axial bearing assembly and the thrust disc. The air compressor reduces a tolerance accumulation caused by part cooperation between axial bearing assemblies, and more precisely ensures effective working clearances.
