Description

Technical Field

[0001] This utility model provides a power supply. Background Technology

[0002] Increased power density in power supplies leads to heat dissipation issues. In current power supply designs, while internal fans are present, they are suspended from the upper casing. This necessitates an assembly structure on the side of the fan frame facing the casing, significantly constraining the design of the upper casing's air vents. Furthermore, to achieve better heat dissipation, power supplies employ high-pressure cooling designs. The fan is positioned above the electronic components, generating airflow through the upper casing vents to the components when activated. However, the fan's suspended design limits its effective airflow range, hindering optimal heat dissipation.

[0003] Taiwanese patent application TWI863571 proposes a power supply for a computer that uses multiple fan connectors to assemble a fan onto the lower casing (referred to as the base component). While the fan in this application is not located on the upper casing, the assembly of multiple components results in a complex structure, and any looseness in these components could lead to abnormal operating noise. Furthermore, the fan frame in this application retains the assembly structure previously used for assembling the upper casing, clearly failing to consider the actual impact of the fan's effective airflow range on heat dissipation. Utility Model Content

[0004] The main purpose of this invention is to solve the problems arising from the conventional fan arrangement in power supplies.

[0005] To achieve the above objectives, the present invention provides a power supply comprising a housing and a fan disposed within the housing. The housing comprises an upper shell and a lower shell connected to the upper shell. The lower shell has a base and two end plates disposed on two opposite parallel sides of the base. Each of the two end plates has a plurality of assembly lugs extending toward the other end plate. The fan comprises a fan frame forming an airflow channel, the airflow channel providing a fan blade assembly disposed therein and having a first axial direction. The fan frame has a plurality of mounting portions that can overlap the assembly lugs, each of the mounting portions being assembled along a second axial direction intersecting the first axial direction.

[0006] In one embodiment, each of the mounting portions has a fixing hole, a mating surface formed with the fixing hole, and one or more positioning protrusions protruding relative to the mating surface, the positioning protrusions being located at least on two adjacent sides of the mating surface.

[0007] In one embodiment, the fan frame has a gap between its two sides that do not contact the two end plates.

[0008] In one embodiment, one of the end plates has a plurality of output port openings.

[0009] In one embodiment, the lower shell has a plurality of skirts located on the sides of the two end plates, each skirt having an assembly hole for assembling the upper shell.

[0010] In one embodiment, each of the assembly lugs has a threaded hole facing the fixing hole.

[0011] In one embodiment, the upper housing has one or more air vents, and the fan frame has an air inlet surface facing the upper housing, the effective air inlet range of which is rectangular.

[0012] In one embodiment, the fan frame has an air inlet ramp on the air inlet surface that connects to the airflow channel. The air inlet surface is rectangular and the air inlet ramp extends from the four corners of the air inlet surface.

[0013] In one embodiment, the fan frame does not have a structure for assembling the upper shell on the air inlet surface.

[0014] In one embodiment, the fan frame has a top plate forming the air inlet surface and a bottom plate opposite the top plate, with the mounting portions formed on the bottom plate or the top plate.

[0015] In one embodiment, each of the mounting parts has a connecting post disposed between the top plate and the bottom plate, and a beam connecting the connecting post, one end of which can overlap one of the mounting lugs.

[0016] In one embodiment, the connecting post is connected to the end corner of the top plate.

[0017] In addition to the foregoing, the present invention also provides a fan for a power supply, the fan comprising a blade assembly and a fan frame. The fan frame forms an airflow channel in which the blade assembly is disposed and has a first axial direction. The fan frame has a plurality of mounting portions, each of which is assembled along a second axial direction intersecting the first axial direction.

[0018] In one embodiment, each of the mounting portions has a fixing hole, a mating surface formed with the fixing hole, and one or more positioning protrusions protruding relative to the mating surface, the positioning protrusions being located at least on two adjacent sides of the mating surface.

[0019] In one embodiment, the fan frame has an inlet ramp connecting the airflow channel, the inlet ramp extending from the four corners of the fan frame.

[0020] In one embodiment, the fan frame has a top plate and a bottom plate opposite the top plate, and the mounting portions are formed on the bottom plate or the top plate.

[0021] In one embodiment, each mounting part has a connecting column disposed between the top plate and the bottom plate, and a beam connecting the connecting column, one end of which can overlap the lower shell.

[0022] Compared to conventional technology, the present invention has the following advantages through the aforementioned technical implementation: Unlike conventional methods where the fan is assembled on the upper housing, the fan of this invention is installed on the lower housing. By changing the assembly method, the side of the upper housing facing the fan does not require corresponding assembly holes. The effective airflow range of the fan facing the upper housing is larger than in conventional methods, effectively increasing airflow and improving the heat dissipation capacity of the power supply. Furthermore, it increases the design flexibility of the air vent on the upper housing. Moreover, the fan of this invention directly connects to the fan frame using assembly lugs that are part of the lower housing's own structure, avoiding the complex assembly of multiple components that could cause noise during operation due to structural loosening.

[0062] Unless otherwise expressly stated or intentionally limited in number, the singular forms “a” and “the” used herein include the plural forms. Furthermore, the term “comprising” as used herein indicates the presence of the described features, elements and / or components, but does not preclude the addition or presence of one or more other features, elements, components and / or groups thereof.

[0063] The descriptions of directions such as "up" and "down" in this article are based on the attached diagram for ease of understanding only, and are not limited to these directions. They can be adjusted according to the actual situation.

[0064] Please see Figures 1 to 4 This utility model provides a power supply 20, which is implemented in ATX or an extended form factor. The power supply 20 includes a housing 21, a fan 22 disposed within the housing 21, and an electronic component 24 disposed within the housing 21. The housing 21 includes an upper shell 211 and a lower shell 212. The upper shell 211 and the lower shell 212 are fitted together; in one embodiment, the upper shell 211 and the lower shell 212 are both U-shaped shells. The upper shell 211 and the lower shell 212 can be selectively assembled or separated. When the upper shell 211 and the lower shell 212 are separated, the electronic component 24 can be inspected or repaired. In this utility model, the lower shell 212 has a base 213 and two end plates 214 disposed on two opposite parallel sides of the base 213. Each of the two end plates 214 has a plurality of assembly lugs 215 extending toward the other end plate 214. The assembly lugs 215 of this invention are integrally formed structures of one of the end plates 214. Specifically, the lower shell 212 is formed by bending a plate. Multiple skirts 216 are formed on the side of the plate at the location where the two end plates 214 are to be formed. The plate is bent in a certain manner, and the structures on these skirts 216 can form the assembly lugs 215. Furthermore, one of the end plates 214 has multiple output port openings 217, which provide corresponding configurations for multiple output connectors (not shown) of the electronic component 24. It should be noted that the assembly lugs 215 of this invention are not limited to having the same structure and can be adjusted according to the structural design.

[0065] Please see Figures 1 to 5On the other hand, the fan 22 of this invention is disposed within the housing 21. The fan 22 includes a blade assembly 221 and a fan frame 222 for housing the blade assembly 221. The blade assembly 221 is activated by power supplied by the electronic component 24 and generates airflow within the housing 21. The blade assembly 221 is not the focus of this invention; those skilled in the art will readily understand and implement it, and will not be elaborated upon here. The fan frame 222 forms an airflow channel 223 in which the blade assembly 221 is disposed, and the airflow channel 223 has a first axial direction 224. The first axial direction 224 intersects the extending axial direction of the base 213, and in one embodiment, the first axial direction 224 is perpendicular to the extending axial direction of the base 213. The fan frame 222 further has a plurality of mounting portions 225, the main purpose of which is for assembling the fan 22 with the housing 21. The mounting portions 225 overlap the mounting lugs 215 during assembly of the fan 22 and the housing 21. The fan 22 is entirely supported by the mounting lugs 215 and located within the space defined by the lower housing 212. Each mounting portion 225 has a fixing hole 226, which is assembled along a second axis 227 intersecting the first axis 224. In one embodiment, the aforementioned second axis 227 is perpendicular to the first axis 224 of the airflow channel 223. The fixing hole 226 provides a set of connectors 251 that pass through it to secure the fan 22 to the housing 21. The connectors 251 may be screws.

[0066] In summary, unlike conventional assembly of the upper housing 211, the fan 22 of this invention is mounted on the lower housing 212. This change in assembly method eliminates the need for corresponding mounting holes on the side of the upper housing 211 facing the fan 22. The effective airflow range of the fan 22 facing the upper housing 211 is larger than conventional methods, effectively increasing airflow and improving the heat dissipation capacity of the power supply 20. Furthermore, it increases the design flexibility of the air vents on the upper housing 211. Moreover, the fan 22 of this invention uses mounting lugs 215, which are part of the lower housing 212's own structure, for direct connection, preventing noise caused by the complex assembly of multiple components during operation.

[0067] Please refer to the following: Figures 1 to 4In one embodiment, each of the mounting portions 225 has a mating surface 228 with the fixing hole 226 formed therein, and one or more positioning protrusions 229 protruding relative to the mating surface 228. The mating surface 228 refers to the surface of each of the mounting portions 225 directly opposite one of the assembly lugs 215 when the fan frame 222 is assembled with the lower housing 212. It should be understood that after the fan frame 222 and the lower housing 212 are assembled, the mating surface 228 is not limited to contacting one of the assembly lugs 215, but may or may not contact depending on the structural design. The positioning protrusions 229 are located at least on two adjacent sides of the mating surface 228, and the position of the positioning protrusions 229 is primarily to assist in the assembly and positioning of the fan frame 222. The position of the positioning protrusion 229 is set based on the position of one of the assembly lugs 215, and is not limited to the same position of the positioning protrusions 229 on all the assembly lugs 215. On the other hand, each skirt 216 has an assembly hole 219 for assembling the upper shell 211. In this embodiment, the assembly hole 219 directly faces a mounting hole 260 on the upper shell 211 when the upper shell 211 and the lower shell 212 are initially assembled, and provides a mounting member to be disposed between the two, completing the assembly of the upper shell 211 and the lower shell 212. The aforementioned mounting member can be a screw. In one embodiment, each assembly lug 215 has a screw hole 210 for fixing the fan frame 222. The screw hole 210 directly faces the fixing hole 226 when the fan frame 222 is placed on one of the assembly lugs 215.

[0068] Please see Figure 3 and Figure 5 In one embodiment, the two sides 230 of the fan frame 222 facing the end plate 214 do not contact the end plate 214, thus creating a gap 252. As mentioned above, after the fan 22 and the lower housing 212 are assembled, only the mounting parts 225 and the mounting lugs 215 of the fan 22 and the lower housing 212 are in contact, while the rest are not. This reduces the possibility of resonance noise between the fan 22 and the housing 21 when the fan 22 is running.

[0069] Please refer to the following: Figures 2 to 5The upper shell 211 has one or more air vents 218. The fan frame 222 has an air inlet surface 231 facing the upper shell 211, and the effective air inlet range of the air inlet surface 231 is rectangular. In this embodiment, the air inlet surface 231 is rectangular. Since the fan frame 222 of this invention does not need to be assembled with the upper shell 211, the fan frame 222 can use most of the side facing the upper shell 211 (i.e., the air inlet surface 231) for air intake. That is to say, the fan frame 222 does not have a structure for assembling with the upper shell 211 on the air inlet surface 231. Further, the fan frame 222 has an air inlet inclined surface 232 on the air inlet surface 231 that connects to the airflow channel 223, and the air inlet inclined surface 232 extends from the four corners of the air inlet surface 231. As mentioned above, the effective air intake range can be considered not only by the position of the airflow contacting the air intake surface 231, but also by the area of ​​the air intake inclined surface 232 in this utility model.

[0070] Please refer to the following: Figures 2 to 5 The fan frame 222 of this invention has a top plate 233 forming the air inlet surface 231 and a bottom plate 234 opposite to the top plate 233. The mounting portions 225 are formed on the bottom plate 234, but are not limited to being formed on the bottom plate 234; they can also be formed on the top plate 233 for assembly. Further, each mounting portion 225 has a connecting post 235 disposed between the top plate 233 and the bottom plate 234, and a beam 236 connecting the connecting post 235. One end of the beam 236 can rest on one of the assembly lugs 215; that is, the end face of the beam 236 facing one of the assembly lugs 215 is the assembly surface 228 mentioned in the foregoing embodiments. The beam 236 can be located on the top plate 233 or the bottom plate 234 depending on the position of one of the mounting portions 225. Furthermore, the connecting column 235 is connected to the corner of the top plate 233, which is the corner of the air inlet surface 231.

All equivalent variations and modifications made in accordance with the claims of the present utility model should still fall within the patent coverage of the present utility model.
