Heat dissipation fan with reflecting surface

Abstract

A heat dissipation fan with a reflecting surface, comprising a fan frame. The fan frame has a bearing seat and a surrounding wall part enclosing the bearing seat. The surface of the surrounding wall part has a reflecting surface. When an external light source is illuminated on the reflecting surface, the reflecting surface on the fan frame of the fan can reflect the light source, and the surrounding wall part can visually appear to have a light source projection effect like a lamp, thereby increasing the cool visual feeling of the overall appearance of the heat dissipation fan.

Description

Technical Field

[0001] This utility model relates to a fan, and more particularly to a cooling fan with a reflective surface added to the fan frame, which forms a reflective light source effect when illuminated by a light source. Background Technology

[0002] In recent years, in addition to improvements in basic functions such as quiet operation, power consumption and fault detection, the small fans used inside various electronic devices have also evolved into small fans with diverse shapes and lighting effects.

[0003] Current small fans, for example, have a row of light-emitting diodes mounted on the fan blade hub. Controlled by an IC circuit, they can display cool visual effects such as 3D images, numbers, or text as the fan blades rotate. This is known as the persistence of vision, which refers to the phenomenon where, when the human eye observes an object, the light signal is transmitted to the brain. After a short period of time, the visual image does not immediately disappear; the human eye can retain the image for about 0.1 seconds. This residual vision is called persistence of vision.

[0004] Alternatively, the fan blades and frame can be made of transparent light-guiding plastic material, and several light-emitting diodes can be installed on the fan's circuit board or frame. When the circuit board drives the fan blades to rotate, these light-emitting diodes are lit at the same time, so that the light source generated by these light-emitting diodes is projected onto the fan frame or fan blades, so that the fan frame and fan blades produce a light-emitting effect when they rotate.

[0005] Although the aforementioned fan structure has a light source display effect, the overall structure and circuit design are relatively complex and the manufacturing cost is high, which in turn increases the price of the fan.

[0006] Therefore, the challenge this creation aims to address is how to make the fan blades produce a light source effect while rotating, and at the same time make the fan easier to manufacture and reduce production costs. Utility Model Content

[0007] Therefore, the main purpose of this creation is to address the shortcomings of traditional designs. This creation redesigns the cooling fan by adding a reflective surface to the peripheral wall of the fan frame. When external light shines on the reflective surface, the reflective surface on the peripheral wall reflects the light, creating a visually striking light projection effect on the fan frame, thus enhancing the overall cool visual appeal of the cooling fan.

[0008] This invention provides a cooling fan with a reflective surface, comprising: a fan frame; a support base and a peripheral wall portion surrounding the support base; wherein, the surface of the peripheral wall portion has a reflective surface.

[0009] Furthermore, the reflective surface is composed of a plurality of recesses, each of which has a spacing between it.

[0010] Furthermore, the reflective surface is composed of a plurality of recesses, each of which is arranged in a continuous, uninterrupted manner.

[0011] Furthermore, the reflective surface is composed of a plurality of protrusions, each of which has a spacing between it.

[0012] Furthermore, the reflective surface is composed of a plurality of protrusions, each of which is arranged in a continuous, uninterrupted manner.

[0013] Furthermore, the surface of the peripheral wall is either the top surface or the side surface.

[0014] Furthermore, the reflective surface is disposed on the surface of the support.

[0015] Furthermore, the surface of the support is either the top surface or the side surface.

[0016] Furthermore, the peripheral wall is provided with a plurality of fixing parts, which fix the fan frame to the heat dissipation fins.

[0017] Furthermore, a central shaft protrudes upward from the inner center of the support base, the central shaft having a shaft hole in which at least one bearing is disposed, and an assembly space is formed between the outer periphery of the central shaft and the peripheral wall, the assembly space being used to assemble coil assemblies, circuit boards and fan blades.

[0041] The technical details and specific descriptions of this work are explained below with accompanying illustrations:

[0042] Please see Figure 1 This is a three-dimensional schematic diagram of the fan frame of this invention. As shown in the figure: The reflective cooling fan of this invention mainly adds a reflective light source structure to the fan frame 10 to enhance the overall cool visual appearance of the cooling fan.

[0043] The fan frame 10 has a support base 101 and a peripheral wall portion 102 surrounding the support base 101. Furthermore, a plurality of fixing portions 1021 are provided on the peripheral wall portion 102 for fixing the fan frame 10 to heat sink fins (not shown) or other heat dissipation devices (not shown). Additionally, a central shaft 103 protrudes upward from the inner center of the support base 101, and the central shaft 103 has a shaft hole 1031 in which at least one bearing (not shown) is disposed. Furthermore, an assembly space 104 is formed between the outer periphery of the central shaft 103 and the peripheral wall portion 102, and the assembly space 104 is used to assemble the coil assembly (not shown), the circuit board (not shown), and the fan blade 20.

[0044] A reflective surface 105 is provided on the surface of the peripheral wall portion 102 and the support base 101, and a reflective surface 105 is provided on the fan frame 10 and the fan blade 20 (e.g. Figure 5 After assembly (as shown), when an external light source shines on the reflective surface 105, the reflective surface 105 will reflect or refract the light source, and visually, the fan frame 10 will produce a light source projection effect like a lamp, thereby increasing the overall cool visual appearance of the cooling fan. In this figure, the surface of the peripheral wall 102 or the support 101 is the top surface or the side surface.

[0045] Please see Figure 2 , tied to Figure 1 A partially enlarged sectional view of the peripheral wall of the sector frame; also refer to... Figure 1As shown in the figure: When making the fan frame 10 of this invention, a pattern design of a reflective surface 105 is added to the mold cavity of the mold (not shown in the figure) for making the fan frame 10. After the fan frame 10 is injection molded, a reflective surface 105 will be formed on the surface of the peripheral wall 102 of the fan frame 10.

[0046] The reflective surface 105 is composed of a plurality of recesses 1051, with a spacing 1052 between each recess 1051. In the fan frame 10 and fan blade 20 (as shown in the image...), Figure 5 After assembly (as shown), when an external light source shines into the recesses 1051, the recesses 1051 will reflect the light source, making the peripheral wall 102 of the fan frame 10 visually visible, producing a light source projection effect like having a lamp, thereby increasing the overall cool visual feel of the cooling fan.

[0047] Please see Figure 3 ,Tie Figure 2 Another embodiment diagram; also refer to Figure 1 , 2 As shown in the figure: This embodiment and Figure 2 They are largely the same, except that the aforementioned recesses 1051 are arranged with a spacing 1052 between them. Figure 3 The recesses 1051 are arranged in a continuous manner with no gaps between them.

[0048] Similarly, in the fan frame 10 and fan blade 20 (as shown) Figure 5 When assembled together, when an external light source shines into the recesses 1051, the recesses 1051 will reflect the light source, making the peripheral wall 102 of the fan frame 10 visually visible as having a light source projection effect, thereby increasing the overall cool visual appearance of the cooling fan.

[0049] Please see Figure 4 ,Tie Figure 2 A schematic diagram of another embodiment; see also the attached diagram. Figures 1-3 As shown in the figure: More notably, the recessed holes 1051 of the reflective surface 105 (105a) can also be protrusions 1051a. Each protrusion 1051a is arranged with a spacing 1052a or without spacing on the surface of the peripheral wall portion 102. This is also true for the fan frame 10 and the fan blades 20 (e.g., ...). Figure 5 After assembly (as shown), when an external light source shines on these protrusions, these protrusions will reflect the light source, making the surface of the peripheral wall 102 of the fan frame 10 visually appear as if it has a light source projection effect, thereby increasing the overall cool visual experience of the cooling fan.

[0050] Please see Figure 5This is a three-dimensional schematic diagram of the fan blades and frame of this creation. Also referenced... Figures 1-3 As shown in the figure: After the fan blade 20 of this invention is assembled into the assembly space 104 of the fan frame 10, when the circuit board (not shown in the figure) mounted on the support 101 transmits power to the coil group (not shown in the figure), the coil group generates magnetic force, which can drive the magnetic element (not shown in the figure) arranged inside the hub 201 of the fan blade 20, so that the fan blade 20 rotates.

[0051] After the fan blades 20 and the fan frame 10 are assembled, when an external light source shines on the recesses 1051 of the reflective surface 105 of the peripheral wall portion 102, the recesses 1051 will reflect the light source, so that the surface of the peripheral wall portion 102 of the fan frame 10 will be visually seen to produce a light source projection effect like having a light, thereby increasing the overall cool visual experience of the cooling fan.
