Description
Technical Field
The present invention relates to a frame, and more particularly, to a fan frame of a fan.
Background
With the continuous progress of technology, the sizes of integrated circuits and electronic components are becoming more miniaturized, so that the integrated circuits and electronic components can be configured with higher density, thereby generating strong computing power and functionality, but good heat dissipation is also required to maintain normal operating temperature, and a common heat dissipation fan is a heat dissipation device that achieves good air cooling effect by driving airflow or fluid through rotating fan blades. The common heat dissipation fan usually generates unpleasant noise during operation, which is mainly caused by (1) the noise generated by the vibration of the fan blades, and (2) the noise generated at the air inlet and the air outlet due to the disturbance of the air flow or the disturbance of the flow field when the air flow passes through the fan. The main reason of the former is that the fan blades cause overall vibration, which causes the fan frame to collide with the installation environment to generate noise, and the noise can be reduced by disposing a buffer component between the fan frame and the installation environment or strengthening the bonding strength between the components. However, the latter not only generates a large noise, but also cannot be overcome by the buffering component or the enhanced bonding strength, and thus is a problem to be overcome in the field of heat dissipation fan technology.
Referring to fig. 1 and 2, in order to solve the aforementioned noise problem, the patent of the people's republic of china No. CN105317749A discloses a fan frame, wherein the fan frame 1 includes a bearing seat 11, and an outer frame 12 surrounding the bearing seat 11 and connected to the bearing seat 11. The outer frame 12 includes a top wall 121, an inner wall 122 connected to an inner edge of the top wall 121 and extending downward, an outer wall 123 connected to an outer edge of the top wall 121 and extending downward, and a bottom wall 124 connecting bottom edges of the inner wall 122 and the outer wall 123. The top wall 121, the inner wall 122, the outer wall 123, and the bottom wall 124 cooperate to define a chamber 125, and the bottom wall 124 defines a plurality of openings 126 that communicate with the chamber 125. The outer frame 12 defines an air inlet 13 and an air outlet 14, and through an opening 126 communicating with the air outlet 14, the airflow flowing from the air inlet 13 to the air outlet 14 is introduced into the opening 126 and enters the cavity 125, and a vortex is formed at the opening 126 through the above manner to absorb a part of the turbulent flow at the air outlet 14, thereby achieving the effect of reducing the noise at the end of the air outlet 14.
However, in order to form the cavity 125 inside the outer frame 12, the design of increasing the area of the top wall 121 is adopted, which increases the frontal area of the outer frame 12 toward the air inlet 13, and rather, increases the noise at the air inlet 13; moreover, the thick outer frame shape of the top wall portion 121 of the outer frame 12 does not meet the trend of light and thin fan frame without occupying space; in addition, after the air flows enter the same chamber 125 through the plurality of openings 126, the air flows are likely to collide with each other due to the opposite directions, and finally resonance is generated in the chamber 125, which increases noise, so that the fan frame 1 still needs to be improved in noise reduction.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and examples.
Referring to fig. 3 and 4, the first embodiment of the fan frame for reducing noise according to the present invention includes an outer frame 2 surrounding an inner space 20, a shaft tube base 3 located in the inner space 20 and surrounded by the outer frame 2, a plurality of stationary blades 4 extending from an outer wall surface 30 of the shaft tube base 3 toward the outer frame 2, and four diaphragms 5 connecting the plurality of stationary blades 4. In the first embodiment, the outer frame 2 is formed by fastening an upper portion and a lower portion, but may also be integrally formed, and not limited thereto, the inner space 20 has an air inlet 201 and an air outlet 202 located below the air inlet 201, and the inner space 20 is configured to allow an air flow to enter from the air inlet 201 along a flow direction a (in the first embodiment, the up-down direction) and to flow out from the air outlet 202.
Each stationary blade 4 is separated from the bottom 301 of the shaft holder 3 and adjacent to the top 302 of the shaft holder 3 in the flow direction a, and extends obliquely upward from the outer wall surface 30 of the shaft holder 3 as shown in fig. 4, wherein a part of the stationary blades 4 are connected to the diaphragm 5, and the remaining stationary blades 4 are connected to the inner wall surface 21 of the outer frame 2. A gap 41 for communicating the air inlet 201 and the air outlet 202 is formed between any two adjacent stationary blades 4. Each of the diaphragms 5 is connected to a plurality of stationary blades 4 and an inner wall surface 21 of the outer frame 2, and includes a plate portion 51 cooperating with the outer frame 2 to define a partition space 50, and two partition portions 52 spaced apart from each other and connecting the plate portion 51 and the outer frame 2. The bottom edge 511 of the plate body 51 is flush with the bottom end 411 where the corresponding stationary blade 4 is connected. The partition 52 divides the partitioned space 50 into a plurality of chambers 501. The chamber 501 communicates with the inner space 20 and the air outlet 202. In the first embodiment, the number of the diaphragms 5 is four, and the diaphragms are respectively located at four corners of the outer frame 2, but actually, the number of the diaphragms 5 may be different depending on the arrangement requirement and may be arranged at different positions, and each diaphragm 5 may be connected with only one stationary blade 4, which should not be limited to this.
When the airflow enters the air inlet 201, the airflow is sent out from the air outlet 202 after passing through the gap 41 between the stationary blades 4, and a part of the airflow flows into the chamber 501 communicated with the air outlet 202, so that a vortex is generated near the air outlet 202, and thus, the turbulent flow of the air outlet 202 can be absorbed and reduced, and the noise at the air outlet 202 can be reduced. In addition, since the chamber 501 is partitioned by the partition board 5 and the outer frame 2 instead of being accommodated in the outer frame 2, the chamber 501 is formed without increasing the thickness or volume of the outer frame 2, which not only can avoid the increase of noise at the air inlet 201 due to the increase of windward area, but also can make the outer frame 2 light and thin to meet the current market trend, and the partitioned chambers 501 can avoid the collision of airflows in different directions to generate resonance, thereby further suppressing noise.
Referring to fig. 5, 6, and 7, as mentioned above, the outer frame 2 may be a combined design as shown in fig. 4, or an integrally formed design as shown in fig. 5 to 7, such that the separating portion 52 of the partition board 5 is integrated with the outer frame 2, and the plate body 51 of each partition board 5 may extend (i.e. extend downwards) towards the air outlet 202 along the flow direction a as shown in fig. 5, so that the bottom edge 511 of the plate body 51 is closer to the air outlet 202 than the bottom end 411 of the connecting portion of the corresponding stationary blade 4, and in order to enable the chamber 501 to communicate with the inner space 20, the bottom edge 511 of the plate body 51 is located in the inner space 20 and does not exceed the air outlet 202. As shown in fig. 6, the top edge 512 of the plate portion 51 may extend toward the air inlet 201 in a direction opposite to the flow direction a (i.e., the top edge 512 extends upward), the top edge 512 of the plate portion 51 may be integrally connected to the outer frame 2, and the partition portion 52 may be located above the stationary blade 4. Of course, as shown in fig. 7, the plate portion 51 may also have a top edge 512 and a bottom edge 511 extending upward and downward (i.e., extending toward the air inlet 201 and the air outlet 202, respectively), the top edge 512 being integrally connected to the outer frame 2, and the bottom edge 511 being closer to the air outlet 202 than a bottom end 411 of a connection portion of the corresponding stationary blade 4 and being located in the internal space 20. The different configurations described above can adjust the depth of the chamber 501 and the overall structural strength, thereby improving versatility.
Referring to fig. 8 to 11, a second embodiment of a fan frame for reducing noise according to the present invention is substantially the same as the first embodiment, except that: the shaft tube base 3 includes a base portion 31 and a plurality of spacers 32 connecting a plurality of the stationary blades 4 and the base portion 31. The spacing portion 32 and the seat portion 31 cooperate to define a spacing space 33 communicating with the inner space 20. Each of the spacers 32 has a receiving section 321 extending toward the outlet 202 along the flowing direction a and having a bottom located in the inner space 20, and a plurality of connecting sections 322 connecting the seat portion 31 and the receiving section 321. The connecting sections 322 divide the space 33 into a plurality of sound absorbing chambers 331 (only one connecting section 322 is shown in each partition 32 in fig. 8). The configuration of the second embodiment not only maintains the chamber 501 of the first embodiment, but also forms a plurality of sound absorbing chambers 331 inside the chamber 501 to further guide the flow to generate a vortex to absorb and reduce the turbulent flow, and the second embodiment also can make the outer frame 2 light and thin without increasing the volume of the outer frame 2. As in the first embodiment, the bottom edge 511 of the plate body 51 of each partition 5 of the second embodiment may also extend downward as shown in fig. 9 to be closer to the air outlet 202 than the bottom end 411 of the corresponding stationary blade 4, or the bottom edge 511 of the plate body 51 may be flush with the bottom end 411 of the corresponding stationary blade 4 as shown in fig. 10 (as in fig. 8), but the partition 52 is located above the corresponding stationary blade 4, so as to meet different structural requirements, or as shown in fig. 11, the partition 5 also has the feature that the plate body 51 extends downward and the partition 52 is located above the corresponding stationary blade 4, which shows that the second embodiment may also have various configurations as required.
Referring to fig. 12, a third embodiment of a fan frame for reducing noise according to the present invention is substantially the same as the second embodiment, except that: in the third embodiment, the diaphragm 5 is not provided (see fig. 11), but the aforementioned spacer 32 is provided only on the shaft holder 3, and both ends of each corresponding stationary blade 4 are connected to the outer wall surface 320 of the corresponding spacer 32 and the inner wall surface 21 of the outer frame 2, respectively, so that the outer frame 2 can be further thinned, and the arrangement can be made compact by shortening the extending length of the stationary blade 4, and thus the third embodiment can be applied to a smaller electronic component with competitiveness and versatility.
In summary, in the present invention, the airflow is introduced through the cavity 501 and the sound absorption chamber 331 to form a vortex, so as to reduce and absorb turbulence formed at the air outlet 202, thereby achieving the noise reduction effect, and the cavity 501 and the sound absorption chamber 331 are not hidden in the outer frame 2, so that the thin design of the outer frame 2 can be maintained without increasing the volume of the outer frame 2, thereby achieving the object of the present invention.
