Description

Technical Field

[0001] This utility model relates to a fan structure, and more particularly to a fan structure having a color-changing body that changes color according to temperature. Background Technology

[0002] In electronic devices, air cooling systems can be used to cool down the heat sources.

[0003] However, air-cooling systems only have the function of cooling; without additional temperature detection components, it is impossible to directly infer the current temperature of electronic devices from the air-cooling system. Therefore, how to design an air-cooling system that can visually infer the current temperature of electronic devices has become a problem that those in the field urgently need to solve. Utility Model Content

[0004] The present invention provides a fan structure that can provide real-time visual temperature indication while providing air cooling.

[0005] An embodiment of this invention discloses a fan structure comprising a housing, a fan, and at least one color-changing element. The fan is rotatably disposed within the housing. The at least one color-changing element is disposed in the housing or the fan, and is configured to display different colors according to temperature.

[0006] In the aforementioned fan structure, at least one color-changing element is embedded in the housing or the fan.

[0007] In the aforementioned fan structure, the at least one color-changing body is embedded in the housing or the fan by injection molding.

[0008] In the aforementioned fan structure, the at least one color-changing element accounts for 0.1 to 5% w / w of the weight percentage of the housing or the fan.

[0009] In the aforementioned fan structure, the radial diameter of the at least one color-changing body is 310 μm ± 10%.

[0010] In the aforementioned fan structure, the at least one color-changing body comprises an invisible dye, at least one color-forming agent, and at least one temperature-regulating agent.

[0011] In the aforementioned fan structure, the at least one color forming agent comprises multiple temperature-sensitive powders, and the colors of these temperature-sensitive powders are all different.

[0012] In the aforementioned fan structure, the temperature-sensitive powders include a first temperature-sensitive powder, a second temperature-sensitive powder, a third temperature-sensitive powder, and a fourth temperature-sensitive powder, and the first to fourth temperature-sensitive powders correspond to rose red, blue, yellow, and violet, respectively.

[0013] In the aforementioned fan structure, at least one temperature control agent includes a first temperature control agent, a second temperature control agent, a third temperature control agent, and a fourth temperature control agent, and the operating temperatures of the first temperature control agent to the fourth temperature control agent correspond to 43°C, 38°C, 31°C, and 25°C, respectively, so as to selectively present the colors of the first temperature-sensitive powder to the fourth temperature-sensitive powder.

[0014] In the aforementioned fan structure, the color change range of the at least one chromophore is -15°C to 70°C.

[0015] According to the fan structure disclosed in the above embodiments, since the at least one color-changing body can display different colors according to the temperature, the housing or fan provided with the at least one color-changing body can display at least two different colors before and after the at least one color-changing body changes color, thereby providing a real-time visual temperature indication. This allows users to intuitively know the approximate temperature of the fan by observing the fan structure, thus enhancing the user's sense of security.

[0024] AA: Region Detailed Implementation

[0025] Please refer to Figures 1 to 2 ,in Figure 1 This is a perspective view of a fan structure according to an embodiment of the present invention, and Figure 2 for Figure 1 An enlarged schematic diagram of the AA region of the fan structure.

[0026] In this embodiment, a fan structure 10 is provided, which includes a housing 11, a fan 12 and a plurality of color-changing elements 13.

[0027] The housing 11 can be installed near a heat source (not shown), such as a central processing unit. A fan 12 is rotatably disposed within the housing 11 to generate airflow to the heat source for heat dissipation. Note that this invention is not limited to the appearance of the housing 11 and fan 12 shown in the figures.

[0028] The color-changing element 13 can be disposed in the fan 12. Furthermore, the color-changing element 13 can be embedded within the fan 12 by injection molding. A single color-changing element 13 can be a granular or cylindrical color masterbatch. The radial diameter of a single color-changing element 13 can be 310 μm ± 10%. In one manufacturing method, the color-changing element 13 can be mixed into the material of the fan 12 at a weight percentage of 0.1 to 5% w / w, and the appearance of the fan 12 can be formed by injection molding, thereby achieving a fan 12 with the color-changing element 13 embedded. Note that the size of the color-changing element 13 shown in the figures is merely an example, and the present invention is not limited thereto. Note that the present invention is not limited to the injection molding manufacturing method. In some embodiments, the color-changing element can also be disposed in the housing. In other embodiments, the color-changing element can be disposed in both the housing and the fan.

[0029] The chromophore 13 can exhibit different colors depending on the temperature, and the color change range of the chromophore 13 can be from -15°C to 70°C. Furthermore, each chromophore 13 comprises an invisible dye, a color-forming agent, and a temperature-regulating agent (not shown separately). The temperature-regulating agent determines whether the chromophore 13 will exhibit the colorless color of the invisible dye or the color-forming agent, depending on the temperature.

[0030] For example, these color changers 13 can be divided into four groups. The color-forming agents in these four groups of color changers 13 can respectively include a first temperature-sensitive powder, a second temperature-sensitive powder, a third temperature-sensitive powder, and a fourth temperature-sensitive powder. The first to fourth temperature-sensitive powders correspond, for example, to rose red, blue, yellow, and violet, respectively. The aforementioned blue, rose red, and yellow are, for example, the three primary colors of pigment (cyan, magenta, yellow; CMY), and the color code of violet is, for example, #84329B. The temperature-regulating agents in these four groups of color changers 13 can respectively include a first temperature-regulating agent, a second temperature-regulating agent, a third temperature-regulating agent, and a fourth temperature-regulating agent. The operating temperatures of the first to fourth temperature-regulating agents correspond, for example, to 43°C, 38°C, 31°C, and 25°C, respectively.

[0031] The material of fan 12 can be, for example, light blue. When the temperature around fan 12 is greater than or equal to 43°C, the first to fourth temperature-regulating agents cause the color-changing body 13 in which they are located to appear colorless, like an invisible dye. Therefore, the overall fan structure 10 will appear light blue, like the material of fan 12, at fan 12. When the temperature around fan 12 is greater than or equal to 38°C and less than 43°C, the first temperature-regulating agent causes the color-changing body 13 in which it is located to appear rose red, like the first temperature-sensitive powder. The second to fourth temperature-regulating agents cause the color-changing body 13 in which they are located to appear colorless, like an invisible dye. Therefore, the overall fan structure 10 will appear light purple, a mixture of the light blue of the material of fan 12 and the rose red of the first temperature-sensitive powder, at fan 12. When the temperature around the fan 12 is greater than or equal to 31°C and less than 38°C, the first temperature control agent causes the color changer 13 in which it is located to appear rose red, the second temperature control agent causes the color changer 13 in which it is located to appear blue, and the third to fourth temperature control agents all cause the color changer 13 in which they are located to appear colorless, like an invisible dye. Therefore, the overall fan structure 10 will appear at the fan 12 as a mixture of the light blue of the fan 12 material, the rose red of the first temperature control agent, and the blue of the second temperature control agent, forming a royal blue color. When the temperature around the fan 12 is greater than or equal to 25°C and less than 31°C, the first temperature control agent causes the color changer 13 in which it is located to appear rose red, the second temperature control agent causes the color changer 13 in which it is located to appear blue, the third temperature control agent causes the color changer 13 in which it is located to appear yellow, and the fourth temperature control agent causes the color changer 13 in which it is located to appear colorless, like an invisible dye. Therefore, the overall fan structure 10 will appear at the fan 12 as a mixture of the light blue of the fan 12 material, the rose red of the first temperature control agent, the blue of the second temperature control agent, and the yellow of the third temperature control agent. When the temperature around the fan 12 is greater than or equal to 20°C and less than 25°C, the first temperature control agent causes the color changer 13 in which it is located to display the rose red color of the first temperature-sensitive powder, the second temperature control agent causes the color changer 13 in which it is located to display the blue color of the second temperature-sensitive powder, the third temperature control agent causes the color changer 13 in which it is located to display the yellow color of the third temperature-sensitive powder, and the fourth temperature control agent causes the color changer 13 in which it is located to display the violet color of the fourth temperature-sensitive powder. Therefore, the overall fan structure 10 will display a deep purple color at the fan 12, which is a mixture of the light blue of the fan 12 material, the rose red color of the first temperature-sensitive powder, the blue color of the second temperature-sensitive powder, the yellow color of the third temperature-sensitive powder, and the violet color of the fourth temperature-sensitive powder.

[0032] Please note that the above-described division of the color-changing body 13 into four groups and the presence of first to fourth temperature-sensitive powders and first to fourth temperature-controlling agents are merely examples. This invention is not limited to the aforementioned colors, the number of color types, or the color produced by any color mixture between the color-changing body 13 and the raw materials of the fan 12. Please note that the terms used to describe colors in the above examples are only used to describe different shades of color and are for illustrative purposes only; this invention is not limited thereto.

[0033] According to the fan structure 10 of the above embodiment, since the color-changing body 13 can present different colors according to the temperature, the fan 12 provided with the color-changing body 13 can present the original color of the fan 12 and a mixed color that is mixed with the color corresponding to at least one temperature-sensing powder in the color-changing body 13, thereby providing a real-time visual temperature indication, allowing users to intuitively know the approximate temperature of the fan structure 10 at present by observing it, thus enhancing the user's sense of security.

[0034] Although the present invention has been disclosed above with reference to the foregoing embodiments, it is not intended to limit the present invention. Any person skilled in the art may make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of patent protection of the present invention shall be determined by the scope of protection of the appended claims.
