Description
- This Non-provisional application claims priority under U.S.C.§ 119(a) on Patent Application No(s). 093125864 filed in Taiwan, Republic of China on Aug. 27, 2004, the entire contents of which are hereby incorporated by reference.
- The invention relates to a fan frame, and in particular, to a fan frame for a fan.
- Heat dissipating devices or systems are commonly used in electronic devices. A heat dissipating device can dissipate heat generated by an electronic device, thus preventing the electronic device from overheating or burnout. Heat dissipating devices are particularly important to micro-electronic devices, such as integrated circuits. Currently, the most commonly used heat dissipating device is a fan. Typically, blades are disposed in a case of a fan, and the frame is disposed at a position corresponding to a vent of a computer housing, or near the heat generating electronic devices. When a motor drives the blades to rotate, heat generated by the electronic devices is dissipated and exhausted through the vent.
- Referring to
FIGS. 1A and 1B ,FIG. 1A is a schematic diagram of a case of a conventional axial-flow fan.FIG. 1B is a cross-section of the conventional axial-flow fan inFIG. 1A along the line A-A. In the conventional axial-flow fan 10, afan frame 11 accommodates a motor (not shown in drawings), animpeller 17, and other components. InFIG. 1B , thefan frame 11 is a case having an opening, and the opening penetrates through thecase 11 to separately form anairflow inlet 12 and anairflow outlet 13 on thecase 11. Themotor base 14 is disposed in thecase 11 and is preferably at theairflow outlet 13 for supporting theimpeller 17. A plurality ofstatic blades 16 are radially disposed between thecase 11 and themotor base 14 for guiding airflow F. - Conventionally,
power lines 15 connected with theimpeller 17 are bundled and disposed along one of thestatic blades 16. Also, a limitingstrap 18 is added for fixing the bundledpower lines 15 on thecase 11. Usually, thelimiting strap 18 is disposed a place on thecase 11 where thestatic blade 16 is connected to thecase 11. - In the conventional axial-
flow fan 10, however, thepower lines 15 may block theairflow outlet 13. The bundledpower lines 15 are disposed along one of thestatic blades 16, hence, the smooth airflow entering theairflow inlet 12 encounters a rough surface, which is caused by the bundledpower lines 15, thus producing wind drag and reducing airflow pressure and volume of the axial-flow fan 10. Especially, this disadvantage is more obviously seen in large-sized fans. - Referring to
FIG. 1C ,FIG. 1C is a schematic diagram of a case of another conventional axial-flow fan. In this axial-flow fan, a plurality ofrectangular ribs 19 are radially disposed between thecase 11 and themotor base 14 for supporting themotor base 14. Thepower lines 15 connected to the impeller are disposed behind theribs 19 in order to prevent a rough surface from being formed, as shown inFIG. 1B . Theribs 19, however, cannot satisfy all character requirements of various airflow pressures and volumes during fans' operation. - Embodiments of the invention provide a fan frame and a fan utilizing the same. An exemplary embodiment of a fan frame includes a case, a motor base, at least one airflow guiding component, and a line leading mechanism. The case includes an opening. The motor base is disposed in the case for supporting an impeller. The airflow guiding component is disposed between the case and the motor base. The line leading mechanism is used for positioning a power line and leading the power line out of the case. The line leading mechanism is integrated with one of the airflow guiding components.

- Fan frames and fans can be more fully understood by reading the subsequent detailed description and examples with references made to the accompanying drawings, wherein:
-
FIG. 1A is a schematic diagram of a case of a conventional axial-flow fan. -
FIG. 1B is a cross-section of the conventional axial-flow fan inFIG. 1A along the line A-A. -
FIG. 1C is a schematic diagram of a case of another conventional axial-flow fan. -
FIG. 2A is a schematic diagram of a case of an embodiment of an axial-flow fan. -
FIG. 2B is a cross-section of the axial-flow fan inFIG. 2A along the line B-B. -
FIG. 2C is an enlarged diagram of the ‘Q’ region ofFIG. 2B . - A Fan frame will be described in greater detail in the following. Referring to
FIGS. 2A and 2B ,FIG. 2A is a schematic diagram of a case of an embodiment of an axial-flow fan.FIG. 2B is a cross-section of the axial-flow fan inFIG. 2A along the line B-B. Thefan frame 21 of the fan 20 accommodates amotor base 24, animpeller 27, and a motor (not shown in drawings). The fan 20 is preferably an axial-flow fan appropriate for a large-sized machine, a server system, a combined fan system, or other heat generating electronic devices. - The
fan frame 21 is acase 21 having an opening. Thefan frame 21 also includes amotor base 24, at least oneairflow guiding component 26, and aline leading mechanism 28. InFIG. 2B , the opening penetrates through thecase 21 to separately form anairflow inlet 22 and anairflow outlet 23 on thecase 21. Themotor base 24 is disposed in thecase 21 and preferably at theairflow outlet 23 for supporting theimpeller 27. - The
airflow guiding components 26 are disposed between thecase 21 and themotor base 24. In this embodiment, theairflow guiding components 26 are static blades having functions of guiding airflow F. Theairflow guiding components 26 are radially disposed at theairflow outlet 23. Alternatively, theairflow guiding components 26 can be curved ribs capable of forming a smooth surface and guiding airflow F. Also, the curved ribs can be appropriately resigned for various cambered surfaces in order to achieve required airflow pressures or airflow volumes. - Referring to
FIGS. 2B and 2C ,FIG. 2C is an enlarged diagram of the ‘Q’ region ofFIG. 2B . Theline leading mechanism 28 positions apower line 25 of the fan 20 and leads thepower line 25 out of thecase 21. Theline leading mechanism 28 is integrated with one of thestatic blades 26, i.e. theairflow guiding components 26. Theline leading mechanism 28 includes aline guiding groove 31, and the opening of theline guiding groove 31 faces outside of thecase 21 for allowing thepower line 25 being disposed therein. Theline guiding groove 31 is located below thestatic blade 26, hence, theline leading mechanism 28 does not directly face the airflow F. Thus, smooth airflow entering theairflow inlet 22 encounters smooth surfaces of thestatic blades 26. Then, thestatic blades 26 guide the airflow F to directly exit theairflow outlet 23. Because thepower line 25 is disposed in theline guiding groove 31 below one of thestatic blades 26, it also solves the conventional problem that the bundled power lines block airflow F, and prevents the power lines from blocking airflow F. - Alternatively, the
line guiding groove 31, connected between themotor base 24 and thecase 21, is exposed out of thecase 21, so that thepower line 25 is positioned by theline guiding groove 31 and led out of thecase 21. Additionally, theline guiding groove 31 includes a restrainingportion 29, such as a clasp or a limiting strap, for limiting thepower line 25 in theline guiding groove 31, as shown inFIG. 2A . - Alternatively, one end of the
line guiding groove 31 is connected with themotor base 24, and the other end is connected with thecase 21. Thecase 21 further includes a through hole so that thepower line 25 is disposed in the through hole and thepower line 25 can be led out of thecase 21 by passing through the through hole. - In addition to the
line guiding groove 31, theline leading mechanism 28 can support thepower line 25 in other ways. For example, one of thestatic blades 26 can include a through hole, and thepower line 25 can be disposed in the through hole and led out of thecase 21. - In an embodiment of an axial-flow fan frame, the width of each airflow guiding component can be the same or not, as long as the airflow guiding components satisfy airflow pressure and volume requirements. For example, the width of the
static blade 26 integrated with theline leading mechanism 28 is greater than that of any otherstatic blade 26 which is not integrated with theline leading mechanism 28. In an embodiment of a fan frame, the line guiding groove is integrated with the airflow guiding component to form a smooth surface against the airflow, thus reducing wind drag and potentially improving fan performance. - While the invention has been described by way of example and in terms of several embodiments, it is to be understood that the invention is not limited thereto. To the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
