Therefore, it is indeed necessary to propose a better solution to address the shortcomings of the existing technology. Utility Model Content

[0046] In embodiments of this invention, the electronic device includes a housing and multiple electronic components disposed within the housing. With the rapid development of network data and artificial intelligence technologies, the amount of data that electronic devices need to process and the speed of data processing are increasing daily. This trend causes the electronic components to generate a large amount of heat during efficient operation, which easily accumulates inside the housing.

[0047] Therefore, in order to ensure that electronic components can operate stably within the ideal temperature range, a cooling fan is installed inside the casing. The cooling fan exhausts hot air from inside the casing to the outside or draws cool air from outside into the casing to quickly reduce the temperature inside the casing and dissipate heat from the electronic components inside.

[0048] Because the blades of a cooling fan can easily collide with the casing when rotating, electronic devices typically have multiple protrusions on the casing to support the cooling fan. When the cooling fan is mounted to these protrusions using fasteners, its blades maintain a gap with the casing to prevent them from striking it during operation. However, this design allows hot air inside the casing to easily flow back through these gaps and be drawn back into the casing by the cooling fan, creating a hot air recirculation within the casing. This results in poor airflow within the casing and negatively impacts the device's cooling performance.

[0049] Therefore, in this embodiment of the electronic device, the fan frame partially contacts or abuts against the inner surface of the housing, improving the recirculation of hot air caused by the gap, thereby enhancing the heat dissipation inside the electronic device. Please refer to... Figures 1 to 3As shown, in the first embodiment of the electronic device 1 of this utility model, the electronic device 1 includes a housing 10 and a fan 20. The fan 20 is disposed inside the housing 10 and includes an outer frame 21 and fan blades 22. The outer frame 21 has opposing first sides 211 and second sides 212. The first side 211 of the outer frame 21 is adjacent to the inner surface of the housing 10 relative to the second side 212. Furthermore, the outer frame 21 includes a blocking portion 213A, at least a portion of which contacts or abuts against the inner surface of the housing 10. The fan blades 22 are disposed inside the outer frame 21. For example, the first side 211 and the second side 212 of the outer frame 21 may be the bottom and top of the outer frame 21, respectively, depending on the configuration position of the fan 20 within the housing 10, but this is not a limitation. In this embodiment, the electronic device 1 of this utility model may be a power supply, a computer host, or a server host.

[0050] With the above-described structure, this invention forms a blocking portion 213A on the first side 211 of the outer frame 21, and the blocking portion 213A contacts the inner surface of the housing 10 to prevent hot air in the housing 10 from flowing back to the fan 20, thereby improving the airflow inside the electronic device 1 and enhancing the heat dissipation effect of the electronic device 1. Furthermore, since the blocking portion 213A has a certain thickness, when the blocking portion 213A contacts the inner surface of the housing 10, the fan blade 22 will maintain a gap with the housing 10, thus preventing the fan blade 22 from being damaged by striking the housing 10 during rotation.

[0051] Please see Figure 2 , Figure 4 and Figure 5 As shown, in this embodiment, the outer frame 21 has a first opening 214 and a second opening 215. The first opening 214 is located on the first side 211, and the second opening 215 is located on the second side 212 relative to the first side 211. The first opening 214 and the second opening 215 communicate to further form a mounting groove inside the outer frame 21, and the fan blade 22 is disposed in the mounting groove; wherein, as Figure 5 As shown, the inner edge of the first side 211 is defined along the edge of the first opening 214, and the outer periphery of the outer frame 21 is rectangular, further defining the outer edge of the first side 211 along the outer periphery of the outer frame 21. In this embodiment, the blocking portion 213A extends from the inner edge of the first side 211 of the outer frame 21 towards the inner surface of the housing 10. Furthermore, in this embodiment, a honeycomb-shaped ventilation hole 11 is formed on the housing 10, the position of which corresponds to the position of the fan 20, and the ventilation hole 11 communicates with the first opening 214.

[0052] To enhance the effect of the baffle 213A in preventing the recirculation of hot air, please refer to [link / reference needed]. Figure 5 and Figure 6As shown, in this embodiment, the blocking part 213A is annular in shape and has four short sides and four arc sides. The four short sides are arranged at equal angular intervals, and each short side is perpendicular to the two adjacent short sides. The four arc sides are staggered between the four short sides, and the two ends of each arc side are connected to the two adjacent short sides respectively. In this embodiment, the blocking part 213A is disposed around the first opening 214 and surrounds the first opening 214. In this way, the blocking part 213A will contact the inner surface of the housing 10, thereby enhancing the effect of blocking the backflow of hot air. In addition, in this embodiment, the blocking part 213A can be a continuous ring or a discontinuous ring, and its shape can also be circular, square, or polygonal.

[0053] In this embodiment, the outer frame 21 and the blocking part 213A are integrally formed structures, and the outer frame 21 and the blocking part 213A can be made of the same or different materials. For example, the material used for the blocking part 213A can be foam material (such as polyurethane (PU) or ethylene vinyl acetate (EVA)), so that the blocking part 213A can absorb the vibration generated by the fan 20 during operation, thereby avoiding the problem of resonance noise caused by the vibration being transmitted to the housing 10.

[0054] And such as Figure 3 and Figure 4 As shown, in this embodiment, the first side 211 of the outer frame 21 is further provided with a plurality of fixing holes 216, and the inner surface of the housing 10 is provided with a plurality of bosses 121, the positions of which correspond to the positions of the plurality of fixing holes 216. The bosses 121 protrude from the inner surface of the housing 10 toward the outer frame 21, for example, and each of the plurality of bosses 121 has a through hole 122 for a plurality of fasteners 30 to pass through the through holes 122 of the plurality of bosses 121 and be fixed to the plurality of fixing holes 216, thereby fixing the outer frame 21 inside the housing 10.

[0055] To further illustrate the more detailed construction of fan 20, such as Figure 4 and Figure 5 As shown, in this embodiment, the fan 20 further includes a rotor 23, a stator 24, and multiple support ribs 25. The rotor 23 is equipped with fan blades 22. The rotor 23 and stator 24 are respectively disposed in the mounting slots of the outer frame 21 and connected to each other. The multiple support ribs 25 extend radially outward from the stator 24 as the center and connect to the second side 212 of the outer frame 21 to fix the stator 24 in the mounting slots of the outer frame 21. In this embodiment, the stator 24 drives the rotor 23 to rotate, thereby causing the fan blades 22 to rotate, thus drawing cool air from outside the housing 10 into the housing 10 through the ventilation holes 11 and the mounting slots of the outer frame 21 to dissipate heat from the electronic components (not shown) inside the housing 10.

[0056] For the second embodiment of this utility model, please refer to Figure 7 and Figure 8 As shown, its main technical content is the same as that of the first embodiment (e.g. Figures 1 to 6 The configuration is largely the same as shown, except that the main difference lies in the arrangement of the blocking portion. In this embodiment, the blocking portion 213B extends from the outer edge of the first side 211 toward the inner surface of the housing 10. The blocking portion 213B is annular in shape and has four long sides, each of which is perpendicular to the two adjacent long sides. Furthermore, the two ends of each long side are connected to the two adjacent long sides respectively. In this embodiment, the blocking portion 213B is disposed around and surrounds the first opening 214, so that the blocking portion 213B contacts the inner surface of the housing 10.

[0057] For the third embodiment of this utility model, please refer to... Figure 9 and Figure 10 As shown, its main technical content is the same as that of the second embodiment (e.g. Figure 7 and Figure 8 The configuration is largely the same as shown, except that the main difference lies in the arrangement of the blocking portion. In this embodiment, the blocking portion 213C extends from the inner and outer edges of the first side 211 toward the inner surface of the housing 10. The shape of the blocking portion 213C is also annular, as shown. Figure 9 As shown, the blocking part 213C has four long sides and four arc sides. Each arc side is disposed between two adjacent long sides, and each arc side is connected to two adjacent short sides at both ends. In this embodiment, the blocking part 213C is disposed around the first opening 214 and surrounds the first opening 214, so that the blocking part 213C contacts the inner surface of the housing 10 to further enhance the effect of blocking the backflow of hot air.

[0058] For the fourth embodiment of this utility model, please refer to... Figure 11 As shown, its main technical content is roughly the same as the aforementioned embodiments, except that the main difference is that the first side 211 of the outer frame 21 does not have a blocking part. Instead, this embodiment further includes a blocking member 40, which is disposed between the inner surface of the housing 10 and the first side 211 of the outer frame 21. The blocking member 40 contacts the inner surface of the housing 10 and the first side 211 of the outer frame 21.

[0059] With the above-described structure, this invention provides a blocking member 40 between the inner surface of the housing 10 and the first side 211 of the outer frame 21. The blocking member 40 contacts both the inner surface of the housing 10 and the first side 211 of the outer frame 21 to prevent hot air from flowing back into the fan 20, thereby improving the airflow inside the electronic device 1 and enhancing its heat dissipation. Furthermore, because the blocking member 40 has a certain thickness, when it contacts the inner surface of the housing 10 and the first side 211 of the outer frame 21, the fan blade 22 will maintain a gap with the housing 10, preventing damage to the fan blade 22 from impacting the housing 10 during rotation.

[0060] To further illustrate the detailed construction of the blocking element 40, such as Figure 11 As shown, in this embodiment, the blocking member 40 is annular and has four short sides 41 and four arcuate sides 42. The four short sides 41 are arranged at equal angular intervals, each short side 41 is perpendicular to the two adjacent short sides 41, and the four arcuate sides 42 are staggered between the four short sides 41, with each end of each arcuate side 42 connecting to the two adjacent short sides 41. In this embodiment, the positions of the four short sides 41 and the four arcuate sides 42 of the blocking member 40 correspond to the positions of the inner edges of the first side 211 of the outer frame 21. The blocking member 40 is disposed around the first opening 214, with the four short sides 41 and the four arcuate sides 42 surrounding the first opening 214, and the four short sides 41 and the four arcuate sides 42 contacting the inner surface of the housing 10 and the inner edge of the first side 211 of the outer frame 21, thereby enhancing the effect of blocking the recirculation of hot air.

[0061] In this embodiment, the inner surface of the housing 10 is also formed with a plurality of protrusions 121, the positions of which correspond to the positions of a plurality of fixing holes 216. Furthermore, each of the protrusions 121 has a through hole 122, through which a plurality of fixing members 30 pass and are fixed to the plurality of fixing holes 216. In addition, in this embodiment, the blocking member 40 can be a continuous ring or a discontinuous ring, and its shape can be circular, square, or polygonal.

[0062] For the fifth embodiment of this utility model, please refer to... Figure 12 As shown, its main technical content is the same as that of the fourth embodiment (e.g. Figure 11The design is largely the same as shown, except that the main difference lies in the shape of the blocking member 40. In this embodiment, the blocking member 40 has four long sides 43, each of which is perpendicular to the two adjacent long sides 43, and both ends of each long side 43 are connected to the two adjacent long sides 43 respectively. In this embodiment, the positions of the four long sides 43 of the blocking member 40 correspond to the positions of the outer edges of the first side 211 of the outer frame 21. The blocking member 40 is disposed around the first opening 214, with the four long sides 43 surrounding the first opening 214, and the four long sides 43 contacting the inner surface of the housing 10 and the outer edges of the first side 211 of the outer frame 21.

[0063] Furthermore, in this embodiment, multiple through holes 44 are formed at the connection points between the four long sides 43. The positions of the multiple through holes 44 correspond to the positions of the multiple through holes 122 of the housing 10, so that multiple fasteners 30 can pass through the multiple through holes 122 and multiple through holes 44 of the housing 10 and be fixed to the multiple fixing holes 216 of the outer frame 21, thereby fixing the blocking member 40 between the inner surface of the housing 10 and the first side 211 of the outer frame 21.

[0064] For the sixth embodiment of this utility model, please refer to Figure 13 As shown, its main technical content is the same as that of the fourth embodiment (e.g. Figure 11 The design is largely the same as shown, except that the blocking member 40 has four long sides 43 and four curved sides 42. Each curved side 42 is positioned between two adjacent long sides 43, and each curved side 42 is connected to two adjacent long sides 43 at both ends. In this embodiment, the positions of the four long sides 43 and the four curved sides 42 correspond to the positions of the inner edge and the outer edge of the first side 211 of the outer frame 21. The four long sides 43 and the four curved sides 42 will contact the inner surface of the housing 10, the inner edge and the outer edge of the first side 211 of the outer frame 21 to further enhance the effect of blocking the recirculation of hot air.

[0065] For the seventh embodiment of this utility model, please refer to Figures 14 to 16 As shown, its main technical content is roughly the same as the aforementioned embodiments, except that the main difference is that the first side 211 of the outer frame 21 does not have a blocking part, and there is no blocking member between the inner surface of the housing 10 and the first side 211 of the outer frame 21. In this embodiment, the shape of the housing 10 is different. The housing 10 further has a body 13 and a protrusion 14. The protrusion 14 protrudes outward from the body 13 and is in the shape of a frustum. The protrusion 14 and the body 13 are integrally formed. The first side 211 of the outer frame 21 of the fan 20 contacts the inner surface of the body 13 of the housing 10, and the position of the fan blade 22 corresponds to the position of the protrusion 14 of the housing 10.

[0066] With the above-described structure, this invention features a protrusion 14 on the body 13 of the housing 10, corresponding to the position of the fan blade 22 of the fan 20. This allows the first side 211 of the outer frame 21 to contact the inner surface of the body 13 of the housing 10, preventing hot air in the housing 10 from flowing back to the fan 20. This improves the airflow inside the electronic device 1 and enhances its heat dissipation. Furthermore, since the protrusion 14 protrudes outward away from the fan blade 22, when the first side 211 of the outer frame 21 contacts the inner surface of the body 13, the fan blade 22 will maintain a gap with the protrusion 14 of the housing 10. This prevents the fan blade 22 from being damaged by striking the housing 10 during rotation.

[0067] like Figure 14 and Figure 15 As shown, in this embodiment, the protrusion 14 and part of the body 13 are provided with ventilation holes 11, the positions of which correspond to the positions of the fan 20. Furthermore, in this embodiment, the body 13 is provided with multiple through holes 122, through which multiple fasteners 30 pass and are fixed to multiple fixing holes 216 of the outer frame 21, thereby fixing the outer frame 21 to the body 13.

[0068] The above embodiments are merely specific implementations of the electronic device of this utility model, and are not intended to limit this utility model. In other embodiments, the electronic device of this utility model may include the aforementioned housing and the aforementioned fan disposed within the housing. The fan may include the aforementioned outer frame and the aforementioned fan blades disposed within the outer frame. The first side of the fan may be in contact with the inner surface of the housing using any other method, or at least a portion of the structure of the first side of the fan's outer frame may abut against the inner surface of the housing to prevent hot air in the housing from flowing back to the fan, thereby improving the airflow inside the electronic device and enhancing the heat dissipation effect of the electronic device.
