Description

Technical Field

[0001] This utility model belongs to the technical field of cooling fan products, specifically relating to a cooling fan with a nameplate. Background Technology

[0002] Most cooling fans nowadays have a nameplate on the surface of the fan blade hub to display product information. However, when the cooling fan is working, the nameplate rotates with the fan blades, making it impossible to see the product information on the nameplate and causing visual confusion.

[0003] In addition, existing fan blades consist of a hub and multiple blades located around the hub. The inner ends of the blades are fixed to the outer circumference of the hub and arranged radially around the hub. During operation, the blades rotate, causing the surrounding air to flow. The outer edges of the existing fan blades are connected by rings, causing the airflow to converge in one direction, generating axial airflow. This results in higher air pressure, enabling the cooling of different products and meeting diverse needs.

[0004] The inventors have proposed the following technical solution based on existing technologies. Summary of the Invention

[0005] The purpose of this invention is to provide a cooling fan with a nameplate by combining technical technology.

[0006] This utility model adopts the following technical solution: a cooling fan with a nameplate, comprising: a fan bracket, a central shaft, fan blades, a stator, a rotor, and a nameplate. The fan blades include: a hub, multiple blades integrally formed with the hub and evenly distributed on the outer edge of the hub, and an annular body connected to all the blades for increasing air pressure. The stator is disposed on the fan bracket, and the rotor is disposed inside the hub of the fan blades. The lower end of the central shaft is mounted on the fan bracket. The hub of the fan blades is mounted on the central shaft via bearing components and can rotate relative to the central shaft. The top surface of the hub is formed with a groove for accommodating the nameplate, and the upper end of the central shaft extends from the groove on the top surface of the hub. The nameplate is threadedly connected to the upper end of the central shaft.

[0007] Furthermore, in the above technical solution, the inner edge of the blade is integrally connected to the circumferential side of the hub, and the outer edge of the blade is integrally connected to the circumferential inner side of the annular body; the annular body extends downward to form a baffle corresponding to each blade position, and the lower edge of the baffle coincides with the outer edge of the corresponding blade.

[0008] Furthermore, in the above technical solution, a mounting hole for mounting bearing components is formed in the center of the groove on the top surface of the wheel hub.

[0009] Furthermore, in the above technical solution, the blade has raised ridges formed on both its front and back surfaces.

[0010] Furthermore, in the above technical solution, the nameplate includes: a tray and a panel covering the outer surface of the tray, wherein a nut is fixed at the center of the tray and the nut is threadedly connected to the threaded section at the upper end of the central shaft.

[0011] Furthermore, in the above technical solution, the panel is connected to the outer surface of the tray by adhesive or magnetic attraction.

[0012] Furthermore, in the above technical solution, a spring is sleeved at the lower end of the central shaft, and a retaining ring is provided below the threaded section at the upper end, with the bearing component located between the spring and the retaining ring.

[0013] Furthermore, in the above technical solution, an annular body is provided on the fan bracket along the periphery of the central axis, and the stator is sleeved on the periphery of the annular body.

[0014] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art: 1. When this utility model is in operation, the nameplate will not rotate while the fan blade rotates relative to the central axis, so that the user can always see the information on the nameplate, and it also has a decorative effect.

[0015] 2. The annular body of the fan blade of this utility model extends downward to form a baffle corresponding to each blade position, and the lower edge of the baffle coincides with the outer edge of the corresponding blade. In addition to increasing the wind pressure of the blade along the axial direction of the fan blade, it can also expand the air outlet angle of the fan blade in the horizontal direction, thereby expanding the air outlet range when the fan blade rotates, and thus expanding the heat dissipation area.
