Description

Technical Field

[0001] The utility model relates to a fan, in particular to a fan capable of increasing static pressure. Background Art

[0002] Small fans used in electronic devices, also known as cooling fans, are important components within electronic devices. Their primary function is to draw in cool air from the outside and expel hot air, further improving cooling efficiency and maintaining a reasonable operating temperature within the electronic device.

[0003] In situations where completely free airflow isn't possible, the static pressure generated by the fan is crucial for cooling performance. The higher the static pressure generated by the fan, the stronger the airflow, allowing the air to be delivered further. Without a correspondingly high static pressure, the required air circulation isn't achieved, resulting in reduced cooling and impaired electronic components within the device.

[0004] Therefore, when some fans are unable to generate high static pressure, the airflow becomes weak and cannot be delivered far enough, resulting in poor cooling. Therefore, multiple fans must be installed to provide adequate cooling. Installing more fans not only increases the size of the electronic device to ensure adequate internal installation space, but also increases the labor and time required for installation and production, increasing production costs.

[0005] Therefore, how to improve the small fan so that it has high static pressure, high wind flow intensity, and can send air farther is the problem to be solved by this application. Utility Model Content

[0041] The detailed description and technical content of this application are as follows, with the accompanying drawings. However, the drawings are only provided for reference and explanation and are not intended to limit this application.

[0042] Example 1

[0043] See also Figure 1-3 , which are schematic perspective views, bottom views, and top views of the static pressure bracket in the first embodiment of the present invention. As shown in the figure, the fan capable of increasing static pressure of the present application comprises: a static pressure bracket 10, which comprises a carrier plate 1, two support portions 2 extending from the circumference of the carrier plate 1, two fixing portions 3 connected to the free ends of the two support portions 2, and a static pressure pattern 4 provided on the surface of the two support portions 2. When the fan structure (not shown) is in operation, the fan's static pressure can be increased. A higher static pressure indicates a higher airflow intensity, which can deliver air farther.

[0044] The carrier plate 1 is disc-shaped and has a bottom 11 on it. A central axis 12 is provided at the center of the bottom 11. The central axis 12 has an axial hole 121. The axial hole 121 is used to install a fan blade structure (not shown in the figure), which includes a hub, a coil seat (not shown in the figure) and a bearing (not shown in the figure). In addition to being able to install a circuit board (not shown in the figure) between the central axis 12 and the bottom 11, the bottom 11 is provided with a plurality of holes 111 and a plurality of openings 112. These holes 111 can allow screws (not shown in the figure) to pass through to fix the circuit board, and these openings 112 can allow the wires of the circuit board (not shown in the figure) to pass through the outside of the carrier plate 1.

[0045] Two support portions 2 extend in opposite directions from the circumference of the carrier plate 1 to form a linear arrangement (the angle between the two support portions 2 is 180 degrees). An opening 21 is provided on the surface of one of the support portions 2, and a channel 22 is provided on the back of the support portion 2, which communicates with one of the openings 112. The channel 22 is provided with at least one support plate 23, which corresponds to the opening 21. When a circuit board (not shown) is mounted on the base 11, the wires on the circuit board pass through the opening 112 into the channel 22 and span the extension of the support plate 23 outside the support portion 2, allowing electrical connection to an external control device. In this first embodiment, the support portion 2 is arc-shaped or linear.

[0046] Two fastening portions 3 are attached to the free ends of the support portion 2. Each fastening portion 3 has a set of fastening holes 31 for fastening the static pressure bracket 10 to the fan frame (not shown). The back of one of the fastening portions 3 has a notch 32 that communicates with the channel 22, allowing the circuit board's wires to extend externally and electrically connect to an external control device.

[0047] The static pressure lines 1 4 are provided on the surfaces of the two support parts 2 and adjacent to the connection between the two support parts 2 and the two fixing parts 3. In the first embodiment, the static pressure lines 1 4 are in the form of a plurality of arcuate stripes or a plurality of straight stripes.

[0048] It is worth mentioning that the surfaces of the two support parts 2 include the front, side and back, so the static pressure pattern 4 can be set on the front, side and back of the two support parts 2, or one of the front, side or back or a combination of two or more.

[0049] See also Figure 4 、 5 , which is a top view of the static pressure bracket and the fan blade structure when they are combined in the first embodiment of the present invention. Figure 4 The cross-sectional view at the AA position is also referenced. Figure 1-3 As shown in the figure, the central axis 12 of the static pressure bracket 10 of the present application is pivotally mounted with a fan blade structure 20. The fan blade structure 20 includes at least a hub 201 with a plurality of blades 202. When the hub 201 is driven to rotate by a circuit board (not shown), the airflow generated by the blades 202 passes through the static pressure pattern 14, which can increase the static pressure of the fan. When the static pressure of the fan is higher, the airflow intensity is stronger, and the air can be delivered further.

[0050] Example 2

[0051] See also Figure 6 , is a top view of the static pressure support and fan blade structure in the second embodiment of the present invention. As shown in the figure, this embodiment is substantially identical to the first embodiment, differing in that the surfaces of the blades 202 of the hub 201 are provided with static pressure patterns 5. When the hub 201 is driven to rotate the blades 202, airflow passing through the static pressure patterns 5 on the blades 202 and the static pressure patterns 4 on the surfaces of the two support portions 2 increases the fan's static pressure. The higher the static pressure, the stronger the airflow, enabling the air to be delivered further. In this second embodiment, the static pressure patterns 5 are stepped.

[0052] Example 3:

[0053] See also Figure 7-9 , which are a schematic perspective view, a top view, and a top view of the static pressure bracket in the third embodiment of the present invention when combined with the fan blade structure. This embodiment is substantially the same as the first and second embodiments, except that the two support portions 2 of the static pressure bracket 10 are linear, and the static pressure lines 14 are provided on the front and side surfaces of the two support portions 2.

[0054] When hub 201 is driven to rotate blades 202, airflow passes through the static pressure patterns (not shown) on the surface of blades 202 and the static pressure patterns 1 (4) on the front and side surfaces of the two support portions 2, increasing the fan's static pressure. Higher static pressure increases airflow intensity, allowing air to be delivered farther. In this diagram, the static pressure patterns 1 (4) are in the form of steps, multiple straight lines, or multiple curved lines.

[0055] The above description is only a preferred embodiment of the present application and does not limit the patent scope of the present application. Therefore, any equivalent structural changes made using the contents of the present application specification and drawings are included in the scope of the rights of the present application, which is hereby stated.
