Description

Technical Field

[0001] The present application relates to a fan frame and a fan. Background Art

[0002] With the rapid development of electronic products towards high performance, high frequency, high speed and thinness, the heat generation temperature of heat-generating electronic components is getting higher and higher, which is likely to cause instability, affecting the reliability and service life of the products. Therefore, heat dissipation has become an important issue for electronic products.

[0003] Generally, a cooling fan is used to drive the cold air in the environment to replace the hot air near the heat-generating electronic components to achieve heat dissipation. However, the hot air flowing through the fan frame is likely to cause the air flow direction to be chaotic, resulting in low heat dissipation efficiency. Summary of the Invention

[0005] In addition, it is also necessary to provide a fan having the above-mentioned fan frame.

[0057] The following specific embodiments will further illustrate the present application in conjunction with the above-mentioned drawings. Specific embodiments

[0058] In order to more clearly understand the above-mentioned objects, features, and advantages of the embodiments of the present application, the present application will be described in detail below in conjunction with the drawings and specific embodiments. It should be noted that, without conflict, the features in the embodiments of the present application can be combined with each other.

[0059] Many specific details are set forth in the following description in order to provide a thorough understanding of the embodiments of the present application. The described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the embodiments of the present application.

[0060] Please refer to Figure 1 and Figure 2 , an embodiment of the present application provides a fan frame 100, and the fan frame 100 includes a hollow frame body 10, a plurality of stationary blades 20, and a fixing seat 30. The frame body 10 has a flow channel 11 allowing fluid to pass through, and the flow channel 11 includes an air inlet surface 111 and an air outlet surface 112 arranged opposite to each other. The stationary blades 20 and the fixing seat 30 are arranged in the flow channel 11. The stationary blades 20 are connected between the inner side of the frame body 10 and the outer side of the fixing seat 30, and the stationary blades 20 are inclined with respect to the air inlet surface 111 and the air outlet surface 112. In this embodiment, the fluid is air. In other embodiments of the present application, the fluid may be other gases such as nitrogen, or may also be liquids such as water and ethanol.

[0061] The stationary blade 20 includes a flow-facing surface 21 and a flow-back surface 22 arranged opposite to the flow-facing surface 21. The flow-facing surface 21 faces the air inlet surface 111, and the flow-back surface 22 faces the air outlet surface 112.

[0062] The stationary blades 20 divide the flow channel 11 into a plurality of flow channel areas A, and each flow channel area A includes a first area B close to the flow-facing surface 21 and a second area C close to the flow-back surface 22.

[0063] The fixed seat 30 includes a bottom plate 31, a first side plate 32, and a second side plate 33. The first side plate 32 and the second side plate 33 are connected end to end to form an annular wall 34. The annular wall 34 surrounds the edge of the bottom plate 31 to form a receiving space 35 for receiving the driving motor 202 (please refer to Figure 3 and Figure 4 ). When the driving motor 202 operates, heat is generated.

[0064] The first side plate 32 is provided with a first slot 321 therethrough, and the second side plate 33 is provided with a second slot 331 therethrough. The first slot 321 communicates with the first area B and the receiving space 35, and the second slot 331 communicates with the second area C and the receiving space 35. The first slot 321 is used to introduce the fluid in the first area B into the receiving space 35, and the second slot 331 is used to introduce the fluid in the receiving space 35 into the second area C.

[0065] During specific use, when the air passes through the flow channel 11, it directly meets the oncoming surface 21 and generates a high-pressure area (not shown in the figure) near the oncoming surface 21. On the contrary, a low-pressure area (not shown in the figure) is generated in the area near the backflow surface 22. The high-pressure area substantially coincides with the first area B, and the low-pressure area substantially coincides with the second area C.

[0066] Then, the air in the high-pressure area is introduced into the receiving space 35 through the first slot 321, and the air in the receiving space 35 is led out to the low-pressure area through the second slot 331, while taking away the heat generated by the driving motor 202.

[0067] In the fan frame 100 provided in this application, by providing the first slot 321 on the first side plate 32 and the second slot 331 on the second side plate 33, the air flow flows into the receiving space 35 from the first slot 321 and flows out of the receiving space 35 from the second slot 331, thereby avoiding the chaos of the air flow direction and improving the heat dissipation efficiency. At the same time, standardizing the air flow direction is also beneficial to reducing the noise of the fan 200.

[0068] In this embodiment, a plurality of the static blades 20 are uniformly arranged on the outer side of the annular wall 34. The static blades 20 are inclined in the direction from the air inlet surface 111 to the air outlet surface 112, so that the oncoming surface 21 faces the fluid, and the backflow surface 22 faces away from the fluid.

[0069] In this embodiment, one of the first slots 321 or one of the second slots 331 is arranged between every two adjacent static blades 20, and the number of the first slots 321 is the same as the number of the second slots 331.

[0070] In this embodiment, the frontal surface 21 is exposed in the first slot 321 , so that the high-pressure fluid in the first zone B can enter the accommodating space 35 without any obstacles.

[0071] In this embodiment, the back flow surface 22 is spaced apart from the second slot 331 , thereby increasing the flow distance of the fluid flowing from the accommodating space 35 into the second area C, thereby improving the heat dissipation efficiency.

[0072] In this embodiment, the first side plate 32 is provided with a third slot 324, and the third slot 324 passes through two opposite sides of the first side plate 32, and the third slot 324 connects the first area B and the accommodating space 35. The third slot 324 is connected to the first slot 321 to form a wiring slot 325, and the wiring slot 325 is used to arrange the wires of the driving motor 202.

[0073] In this embodiment, the fan frame 100 further includes a fixing ring 40 , which is sleeved on the outer side of the fixing seat 30 , and each of the stationary blades 20 passes through the fixing ring 40 . The fixing ring 40 is used to connect the plurality of stationary blades 20 into a whole.

[0074] In this embodiment, the fan frame 100 further includes a sleeve fixing seat 50 . The sleeve fixing seat 50 is disposed at the center of the bottom plate 31 . The sleeve fixing seat 50 is used to fix the drive motor 202 and the impeller 201 .

[0075] In this embodiment, the frame 10 is provided with a plurality of fixing holes 12, and the fixing holes 12 pass through two opposite sides of the frame 10. The fixing holes 12 are used to cooperate with fasteners (e.g., screws and nuts) to fix the frame 10 on a casing (e.g., a casing of a desktop computer).

The drive motor 202 is used to drive the moving blade disk 201 to rotate so that the fluid passes through the flow channel 11.

[0077] In this embodiment, the moving blade disk 201 includes a disk 2011, moving blades 2012 and a rotating shaft 2013.
