[0040] The following disclosure provides many different embodiments or examples, and describes specific examples of each component and arrangement manner to implement different features of this disclosure. For example, if this specification describes that a first feature is formed "on" or "above" a second feature, it means that embodiments including direct contact between the first feature and the second feature can be included, and embodiments in which additional features are formed between the first feature and the second feature, so that the first feature and the second feature are not in direct contact can also be included.
[0041] Relative spatial related terms may be used in embodiments. For example, terms such as "below", "above", etc. are used to facilitate the description of the relationship between elements or features in the drawings and other elements or features. Except for the orientations shown in the drawings, these spatial related terms are intended to include different orientations of the device during use or operation. If the device is turned to different orientations (rotated 90 degrees or other orientations), the spatial related terms used herein can also be interpreted in the same way.
[0042] First, please refer to Figure 1 . Figure 1 For some embodiments according to this disclosure, it is a schematic side view showing the fan housing structure 10. As Figure 1 shown, the fan housing structure 10 mainly includes a heat dissipation member 100. The fan 200 is connected and fixed to the heat dissipation member 100 via a suitable connection structure such as a bearing rivet point. In some embodiments, the fan housing structure 10 may further include a housing 300, which is connected to the heat dissipation member 100 and covers the fan 200. Figure 1The configured positions and dimensions of the heat dissipation member 100, the fan 200, and the housing 300 shown are not intended to be limiting, and the user can change the relative positions or relative dimensions of the heat dissipation member 100, the fan 200, and the housing 300 according to actual needs.
[0043] Next, refer to Figure 2 and Figure 3 to describe the first embodiment of the present disclosure. Figure 2 FIG. is a front view of the heat dissipation member 100 of the fan housing structure 10 according to the first embodiment of the present disclosure. Figure 3 FIG. is an exploded perspective view of the heat dissipation member 100 of the fan housing structure 10 according to the first embodiment of the present disclosure. As Figure 2 and Figure 3 shown, the heat dissipation member 100 mainly includes a first side wall 110, a second side wall 120, a first extension portion 130, and a first chamber 150.
[0044] In an embodiment according to the present disclosure, the heat dissipation member 100 may be a vapor chamber, which is composed of two side walls (i.e., the first side wall 110 and the second side wall 120), and a cavity structure (i.e., the first chamber 150) is formed between the two side walls. A working fluid (not shown in the figure) can be stored in this cavity structure to quickly diffuse the heat generated by the local heat source to a large area surface, improving the heat dissipation efficiency. In this way, compared with the conventional fan bearing support structure, by replacing the solid metal plate with a vapor chamber, the thermal conductivity can be significantly increased. Without increasing the structural volume, the heat dissipation efficiency is further improved.
[0045] In addition, in a conventional vapor chamber, metals with relatively low hardness such as copper or copper alloy are usually used to form the side walls. In an embodiment according to the present disclosure, in addition to copper and copper alloy, metal materials with relatively high hardness (for example: Vickers hardness HV is above 100) such as stainless steel, aluminum, titanium, and titanium alloy can be used to form the side walls. It is beneficial to increase the supporting force and provide more stable support for the fan 200.
[0046] In Figure 2 and Figure 3 shown in the first embodiment, the second side wall 120 is arranged opposite to the first side wall 110 and is connected to the first side wall 110. The first side wall 110 and the second side wall 120 may have substantially the same shape. Therefore, in Figure 2 shown in the front view, the first side wall 110 is located directly behind the second side wall 120 and is not visible. In addition, the edges of the first side wall 110 and the second side wall 120 can be connected and fixed together by welding.
[0047] A first chamber 150 is formed between the first side wall 110 and the second side wall 120 connected together. InFigure 3 In the illustrated embodiment, a recess 115 is formed at the first sidewall 110, and the first chamber 150 is disposed in the recess 115.
[0048] In the first embodiment, the first extension 130 is integrally formed with the first sidewall 110 and extends from the first sidewall 110. When the first sidewall 110 is combined with the second sidewall 120, the first extension 130 protrudes from the second sidewall 120, as Figure 2 shown.
[0049] As Figure 2 and Figure 3 shown, the first extension 130 has a first central portion 131. The first central portion 131 has a connection point 135 for connecting the fan 200.
[0050] In the present disclosure, the first central portion 131 refers to a circular area that extends outward a specific diameter length with the connection point 135 as the center. The above specific diameter length is not particularly limited, and the user can change this length according to actual needs.
[0051] In some embodiments, the fan 200 is connected to the connection point 135. In other words, the connection point 135 serves as the bearing riveting point of the fan 200, and the rotation axis 250 of the fan 200 passes through the connection point 135, as Figure 3 shown. In Figure 2 and Figure 3 the illustrated embodiments, it can be seen that there are other openings with different shapes around the connection point 135. These openings can be used to further fix the fan 200 or other components. However, the presence, size, and position of these openings are not limited, and the user can change them according to actual needs.
[0052] In addition, in Figure 1 the illustrated embodiment, the fan 200 and the housing 300 are connected to the side where the second sidewall 120 is located. However, the user can also, according to actual needs, connect the fan 200 and the housing 300 to the side of the first sidewall 110 that faces away from the second sidewall 120.
[0053] In an embodiment of the present disclosure, a heat pipe (i.e., the heat dissipation member 100) is used as the bearing structure of the fan 200. In this way, in addition to supporting the fan 200, the heat dissipation member 100 can effectively improve the heat dissipation efficiency of the fan housing structure 10. Specifically, compared with the conventional fan housing structure, the fan housing structure 10 according to the embodiment of the present disclosure has higher thermal conductivity, and the heat dissipation member 100 of the fan housing structure 10 can be directly assembled to the heat generating element, so as to reduce the welding process required in the manufacturing process and reduce the contact thermal resistance, effectively improving the heat dissipation efficiency. Directly combining the fan 200 with the heat dissipation member 100 to form an active heat dissipation module also helps to reduce the overall manufacturing cost, and without the need for other housing parts, it also helps to thin the overall structure and reduce the height of the overall structure.
[0054] Next, refer to Figure 4 and Figure 5 to describe the second embodiment of the present disclosure. Figure 4 FIG. is a front view of the heat dissipation member 100' of the fan housing structure 10 according to the second embodiment of the present disclosure. Figure 5 FIG. is an exploded perspective view of the heat dissipation member 100' of the fan housing structure 10 according to the second embodiment of the present disclosure.
[0055] In various embodiments of this specification, the same reference numerals are used to denote the same or similar elements. For example, in the heat dissipation member 100' of the second embodiment, the first side wall 110, the second side wall 120, the first extension portion 130, and the first chamber 150 are all the same as the first side wall 110, the second side wall 120, the first extension portion 130, and the first chamber 150 of the heat dissipation member 100 in the above-mentioned first embodiment, and will not be repeated here.
[0056] The difference between the heat dissipation member 100' of the second embodiment and the heat dissipation member 100 of the first embodiment is that the heat dissipation member 100' further includes a second extension portion 140. The second extension portion 140 is integrally formed with the second side wall 120, extends from the second side wall 120, and corresponds to the first extension portion 130.
[0057] In the second embodiment, the second extension portion 140 is disposed opposite to the first extension portion 130 and is connected to the first extension portion 130. The first extension portion 130 and the second extension portion 140 may have substantially the same shape. Therefore, in Figure 4 the front view shown, the first extension portion 130 is located directly behind the second extension portion 140 and is not visible. In addition, in the second embodiment, the whole of the first extension portion 130 and the whole of the second extension portion 140 can be connected and fixed together by welding. That is, the first extension portion 130 and the second extension portion 140 are combined in a manner of connecting with the whole surface.
[0058] AsFigure 4 and Figure 5 As shown in Figure 5 , the second extension portion 140 has a second central portion 141. The second central portion 141 has another connection point 145. The another connection point 145 of the second extension portion 140 corresponds to the connection point 135 of the first extension portion 130. The fan 200 is connected to the connection point 135 and the another connection point 145 simultaneously. In other words, the connection point 135 and the another connection point 145 serve as the bearing rivet points of the fan 200 at the same time, and the rotation axis 250 of the fan 200 passes through the connection point 135 and the another connection point 145, as Figure 5 shown.
[0059] In this embodiment, the area of the second central portion 141 is equal to the area of the first central portion 131. As described above, the diameter lengths of the first central portion 131 and the second central portion 141 are not particularly limited, and the user can change this length according to actual needs. And corresponding to the first central portion 131, in the second central portion 141, other openings with different shapes may also be provided around the another connection point 145 for further fixing the fan 200 or other components.
[0060] In this embodiment, the first central portion 131 and the second central portion 141 are connected together by welding. In the case where punching needs to be performed on the first central portion 131 and the second central portion 141 to form the connection point 135, the another connection point 145 and / or other openings, two different ways of punching can be used. The first way is to first weld the first central portion 131 and the second central portion 141 together as a whole, and then punch both of them together. The second way is to first punch the first central portion 131 and the second central portion 141 separately, and then weld them together along the contour of the holes. The user can decide which punching method to use according to process requirements or welding area, etc.
[0061] Next, refer to Figure 6 to describe the third embodiment of the present disclosure. Figure 6 FIG. Figure 6 is an exploded perspective view of the heat dissipation member 100” of the fan housing structure 10 according to the third embodiment of the present disclosure.
[0062] One of the differences between the heat dissipation member 100” of the third embodiment and the heat dissipation member 100’ of the second embodiment is that the heat dissipation member 100” further includes a second chamber 160.
[0063] In the third embodiment, the first extension portion 130 and the second extension portion 140 are not combined in a manner of being connected by an integral surface. And different from both the first embodiment and the second embodiment, the edge of the first side wall 110 and the edge of the second side wall 120 are not completely fixed together.
[0064] As Figure 6As shown, a recess 116 connected to the recess 115 is formed at the first extension 130. The second chamber 160 is disposed in the recess 116, such that the second chamber 160 is formed between the first extension 130 and the second extension 140, and the second chamber 160 is in fluid communication with the first chamber 150. Therefore, in the third embodiment, the first sidewall 110 and the first extension 130 are used as the first plate member, and the second sidewall 120 and the second extension 140 are used as the second plate member. Then, the edges of the first plate member and the second plate member are connected and fixed together by welding.
[0065] In this case, in addition to the edges, the portions where the first plate member and the second plate member are connected to each other also include the first central portion 131 and the second central portion 141 connected together in the foregoing manner. As Figure 6 shown, the first central portion 131 and the second central portion 141 correspond to the circular region surrounded by the recess 116 in the figure. In other words, in the third embodiment, the second chamber 160 surrounds the first central portion 131 and the second central portion 141. In this way, the working fluid with heat dissipation efficiency can surround the bearing of the fan 200, further increasing the area of the heat pipe to improve the heat dissipation efficiency.
[0066] Next, refer to Figure 7 to illustrate some other embodiments. Figure 7 For some other embodiments according to the present disclosure, a front view schematic diagram showing the combination of the fan 200 and the heat dissipation member 100 is shown. In Figure 7 the illustrated embodiment, when observing along the rotation axis 250 of the fan 200 (for example, Figure 6 the rotation axis 250 in passes through the connection point 135), the coverage area of the fan 200 is larger than the overall area of the heat dissipation member 100. Figure 7 The range marked by the dashed line in represents the range covered by the fan blades of the fan 200. By increasing the diameter length of the fan 200, the heat dissipation efficiency can be further improved. However, the coverage area of the fan 200 is not limited to Figure 7 the illustrated embodiment, and depending on the actual requirements and structural design, its coverage area can be larger or smaller.
[0067] In addition, as Figure 7 shown, a plurality of coupling portions 170 can be provided around the heat dissipation member 100, which can be used to further fix the fan 200 or the housing 300 (see Figure 1 ), and can also be used to couple the heat dissipation member 100 to other components.
[0068] In Figure 1 and Figure 7 , only the embodiments of the combination of the fan 200 and / or the housing 300 and the heat dissipation member 100 are illustrated. However, such combination methods can also be applied to the above-mentioned heat dissipation members 100' or 100".
[0069] In summary, according to the embodiments of the present disclosure, a heat pipe (heat dissipation member 100, heat dissipation member 100', or heat dissipation member 100") is used as a support member for the bearing of the fan 200, so that the cavity structure (the first chamber 150 and / or the second chamber 160) of the heat pipe is directly located below the fan blades of the fan 200. This design is beneficial to improving the heat conduction ability of the fan housing structure 10, and thus enhancing the overall heat dissipation efficiency of the fan 200.
