Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.
An impeller assembly 10 according to an embodiment of the first aspect of the present invention is described below with reference to the accompanying drawings, which impeller assembly 10 has the advantage of being efficient.
As shown in fig. 1-3, an impeller assembly 10 according to an embodiment of the present invention includes a fan housing 100, a moving impeller 200, a guide disk 300, and a guide vane 400.
Specifically, the fan housing 100 includes an air intake port 101 and an air supply port 102. The impeller 200 is rotatably disposed in the housing 100, and the impeller 200 is disposed adjacent to the suction port 101, such that when the impeller 200 rotates, fluid outside the housing 100 is sucked into the housing 100 from the suction port 101 and then is discharged from the air outlet 102. The guide plate 300 is disposed in the fan housing 100, and the guide plate 300 is disposed adjacent to the air supply port 102, and a drainage air channel 301 is defined between the outer peripheral wall surface of the guide plate 300 and the inner peripheral wall surface of the fan housing 100, and the drainage air channel 301 is respectively communicated with the air suction port 101 and the air supply port 102. The guide vane 400 is provided in the fan housing 100, the guide vane 400 is provided around the impeller 200, the outer circumferential wall surface of the guide plate 300 is connected to the guide vane 400, and the outer circumferential wall surface of the guide plate 300 is tangent to the outer circumferential wall surface of the guide vane 400. Here, the connection of the outer circumferential wall surface of the guide disk 300 to the guide vane 400 means that there is no gap between the outer circumferential wall surface of the guide disk 300 and the outer circumferential wall surface of the guide vane 400 in the axial direction (i.e., the up-down direction shown in the drawing) of the guide disk 300.
The operation of the impeller assembly 10 according to the embodiment of the present invention is described below with reference to the accompanying drawings.
When the movable impeller 200 rotates, fluid outside the fan housing 100 is sucked into the fan housing 100 from the air suction inlet 101, the guide vane 400 guides the fluid sucked by the movable impeller 200 to the drainage air channel 301, the guide plate 300 is arranged adjacent to the air supply inlet 102, the outer peripheral wall surface of the guide plate 300 is connected with the guide vane 400, the outer peripheral wall surface of the guide plate 300 is tangential to the outer peripheral wall surface of the guide vane 400, namely, the outer peripheral wall surface of the guide plate 300 forms the side wall of the drainage air channel 301 in the area between the guide vane 400 and the air supply inlet 102, so that the fluid can smoothly flow through the guide vane 400 and enter the drainage air channel 301, then the fluid smoothly flows out of the impeller assembly 10 from the air supply inlet 102 under the guidance of the drainage air channel 301, the fluid cannot generate vortex in the area between the guide vane 400 and the air supply inlet 102, and finally the motor is cooled.
Therefore, according to the impeller assembly 10 of the embodiment of the invention, the motor can be cooled, and the guide disc 300 is arranged at the position adjacent to the air supply outlet 102, so that fluid can smoothly flow out through the air supply outlet 102 under the guidance of the drainage air duct 301, and vortex loss between the guide vane 400 and the air supply outlet 102 is avoided, thereby having higher efficiency, further improving the heat dissipation efficiency of the motor and enhancing the heat dissipation effect of the motor.
According to some embodiments of the present invention, as shown in fig. 1, a longitudinal section of an outer circumferential wall surface of the guide plate 300 is arc-shaped. That is, in a section parallel to the axial direction of the guide plate 300, the shape of the outer peripheral wall surface of the guide plate 300 is arc-shaped. In this way, it is possible to ensure that the fluid flows along the outer circumferential wall surface of the guide disc 300 after flowing through the outer circumferential wall surface of the guide vane 400, further reducing the eddy current loss.
Further, the outer circumferential wall surface of the guide disc 300 is divided into a first ring segment and a second ring segment arranged in the axial direction of the guide disc 300, wherein the longitudinal section of the first ring segment and the longitudinal section of the second ring segment are circular arcs of different radii, i.e., the shape of the first ring segment and the shape of the second ring segment are circular arcs of different radii in a section parallel to the axial direction of the guide disc 300. In this way, the fluid gradually transitions from the guide vane 400 to the supply port 102, and the fluid flow has less vortex loss.
It should be noted that in the description of the present invention, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature.
Advantageously, the first ring segment is more adjacent to the suction mouth 101 than the second ring segment, the radius of the longitudinal section of the first ring segment being greater than the radius of the longitudinal section of the second ring segment. That is, the first ring segment is located above the second ring segment, and in a section parallel to the axial direction of the guide disc 300, the radius of the first ring segment is larger than that of the second ring segment, so that fluid smoothly flows from the outer circumferential wall surface of the guide vane wheel 400 to the outer circumferential wall surface of the guide disc 300, and finally smoothly flows from the air supply port 102 to the stator assembly of the motor.
According to some embodiments of the present invention, as shown in fig. 1-3, a inducer 400 includes a wheel 410 and a plurality of inducer blades 420. The outer circumferential wall surface of the guide disc 300 is connected to the wheel disc 410, and the outer circumferential wall surface of the guide disc 300 is tangent to the outer circumferential wall surface of the wheel disc 410. The plurality of guide vanes 420 are disposed on a surface of the wheel disc 410 facing the air intake 101 (i.e., an upper surface of the wheel disc 410 shown in the drawing), and the plurality of guide vanes 420 are disposed around the movable vane 200, and an air guide channel 421 respectively communicating with the air intake 101 and the air guide channel 301 is defined between two adjacent guide vanes 420, so that fluid sucked into the air housing 100 by the movable vane 200 can smoothly flow into the air guide channel 301 under the guidance of the air guide channel 421. Here, "a plurality of" means two or more.
Further, as shown in fig. 1 and 3, the wheel 410 has a neck 411 extending toward the air supply port 102 in the axial direction of the wheel 410, and the wall of the guide disc 300 facing the air supply port 102 is attached to the neck 411. That is, the neck 411 extends downward from the lower wall surface of the wheel disc 410, and the bottom wall of the guide disc 300 is coupled to the neck 411, thus facilitating the installation of the guide vane 400 and the guide disc 300.
According to some embodiments of the invention, as shown in fig. 1 and 3, a cavity 302 is defined inside the guide disc 300 or between the guide disc 300 and the guide vane 400. Thus, the weight of the parts is reduced, and the materials are saved.
