- A fan module according to the invention comprises a frame, a wire-stopping structure and an impeller, disposed in the frame. The frame comprises an outer wall, a wire groove, at least one fastening portion and at least one positioning portion. The outer wall is sequentially divided into a first side section, a first mid section, a central section, a second mid section and a second side section in a first direction. The extension direction of the major axis of the central section is parallel to the central axis of the frame, and the first direction is perpendicular to the extension direction of the major axis of the central section. The wire groove is formed on the first mid section to accommodate at least one wire. The fastening portion is disposed on one side of the wire groove.

FIG. 1A is perspective schematic diagram showing a fan frame module according to the first embodiment of the invention,FIG. 1B is an exploded view of the fan frame module inFIG. 1A , andFIG. 1C is a lateral view of the fan frame module inFIG. 1A at axial viewing angle. Referring toFIG. 1A ,FIG. 1B andFIG. 1C , thefan frame module 1 includes aframe 11 and a wire-stoppingstructure 12. Theframe 11 includes anouter wall 111 and aninner wall 112. For example, in theframe 11, theouter wall 111 is roughly like a square ring, theinner wall 112 is roughly like a circular ring, and theframe 11 includes four corners. Theinner wall 112 forms an accommodation space A to accommodate the fan, the motor or the circuit board or other elements so as to form a fan module. For the sake of clarity, the fan, the motor or the circuit board or other elements mentioned above are not illustrated. -
FIG. 1D is a lateral view of the fan frame module inFIG. 1A at radial viewing angle. Referring toFIG. 1D , theouter wall 111 is sequentially divided into afirst side section 1111, a firstmid section 1112, acentral section 1113, a secondmid section 1114 and asecond side section 1115 in a first direction D. The extension direction of the major axis of thecentral section 1113 is parallel to the central axis of theframe 11, and the first direction D is perpendicular to the extension direction of the major axis of thecentral section 1113. - The
frame 11 further includes awire groove 113, at least onefastening portion 114 and at least onepositioning portion 115. Thewire groove 113 is formed on the firstmid section 1112 to accommodate at least one wire which may be electrically connected to the circuit board mentioned above and the power supply. Thewire groove 113 may be an arc groove face, or formed with two inclined planes, or it may be formed with two opposite lateral surfaces and a bottom surface. However, the recessed shape of thewire groove 113 is not limited. In the embodiment inFIG. 1C , thewire groove 113 has twolateral surfaces 1131 disposed oppositely, and eachlateral surface 1131 and theouter wall 111 have an included obtuse angle. - The
fastening portion 114 is disposed on one side of thewire groove 113 in the first direction D, and thepositioning portion 115 is disposed on the other side of thewire groove 113 in the first direction D. In the embodiment, thefastening portion 114 and thepositioning portion 115 are respectively located at differentlateral surfaces 1131, and respectively extend from theouter wall 111 to each other. In the embodiment, there are two positioningportions 115 for example. There is an acute included angle between thefastening portion 114 and thelateral surface 1131, and there is another acute included angle between the positioningportion 115 and the otherlateral surface 1131, too. - In the embodiment, the wire-stopping
structure 12 is roughly like a rectangle board which corresponds to thefastening portion 114 and thepositioning portion 115, so the wire-stoppingstructure 12 is held and fixed by thefastening portion 114 and thepositioning portion 115 on theouter wall 111 to firmly cover thewire groove 113. Moreover, the wire-stoppingstructure 12 is detachably connected to thefastening portion 114 and thepositioning portion 115 interferes with the wire-stoppingstructure 12, so the wire-stoppingstructure 12 is located in thewire groove 113 and not exposed from theouter wall 111. Therefore, the wire-stoppingstructure 12 could be sandwiched between thefastening portion 114 and thelateral surface 1131 to connect to thefastening portion 114. Similarly, the other side of the wire-stoppingstructure 12 could also be sandwiched between the positioningportion 115 and the otherlateral surface 1131, so the wire-stoppingstructure 12 can firmly cover thewire groove 113 and it as well as theframe 11 would not be separated. Moreover, the periphery of the wire-stoppingstructure 12 may have fillets or chamfers for assembly of the wire-stoppingstructure 12 and theframe 11. - The wire-stopping
structure 12 has afirst combination portion 121 which and thefastening portion 114 are corresponding concave-convex structures. In the embodiment, thefastening portion 114 is a protruding block, thefirst combination portion 121 is correspondingly an indentation, and the protruding block (the fastening portion 114) engages with the indentation (the first combination portion 121). Besides, in the embodiment, theframe 11 includes two positioningportions 115 which are like protruding blocks. Similarly, the wire-stoppingstructure 12 at the other side opposite to thefirst combination portion 121 has twosecond combination portions 122 corresponding to these positioningportions 115, and thesecond combination portions 122 and thepositioning portions 115 are corresponding concave-convex structures. Namely, thesecond combination portion 122 is correspondingly an indentation, so these positioningportions 115 can correspondingly engage with thesesecond combination portions 122. - Referring to
FIG. 1E , it is a schematic diagram showing the assembly process of the fan frame module inFIG. 1A . When assembling, thesecond combination portion 122 of the wire-stoppingstructure 12 may correspondingly abut thefastening portion 114 first. The abutted point acts as the pivot to rotate the wire-stoppingstructure 12 toward thewire groove 113. Then, the wire-stoppingstructure 12 is pushed in underneath thepositioning portion 115. At the moment, the wire-stoppingstructure 12 is fixed by thefastening portion 114 and thepositioning portion 115 and covers thewire groove 113. Therefore, as to the fan F shown inFIG. 1F , the wire w in thewire groove 113 would not protrude from theouter wall 111 so as to ensure that the wire w would not interfere with external elements or wear. Thus, it is easier to install the fan module. - Besides, in some embodiments, two opposite blind holes may be disposed on the
fastening portion 114, and the line connecting the blind holes is parallel to the axial of the fan for example. Two bumps corresponding to the blind holes are disposed on the wire-stoppingstructure 12. Here, the wire-stoppingstructure 12 and thefastening portion 114 may be assembled by the bumps and the blind holes, so the assembled part of the wire-stoppingstructure 12 is like axial rotation to form a pivot structure. The disposition or location of the blind holes or the bumps may be varied, the above description is for example. - Besides, the
frame 11 may further include a wire-guidingstructure 116 which leads the wire into thewire groove 113 or leads the wire out of thewire groove 113. In the embodiment, the wire-guidingstructure 116 is disposed at one end of thewire groove 113. For example, it is a structure from the bottom of thewire groove 113 along thelateral surface 1131 to the top opening of thewire groove 113, and it is also bent to extend in parallel with theouter wall 111. Here, the wire-guidingstructure 116 forms a holdingspace 1161 communicating with thewire groove 113, so the wire can be held in the holdingspace 1161 and accordingly fixed. It is beneficial to adjust and fix the outlet direction of the wire. - Moreover, referring to
FIG. 1G andFIG. 1H ,FIG. 1G is a perspective diagram showing the frame inFIG. 1A at another viewing angle, andFIG. 1H is an enlarged diagram of the range C inFIG. 1G . In the embodiment, theframe 11 may further include anoutlet hole 117 which communicates with thewire groove 113 and the accommodation space A. Thus, the wire passes through theoutlet hole 117 from the accommodation space A to thewire groove 113. In other words, theoutlet hole 117 is the outlet hole of the wire. Besides, theoutlet hole 117 may be a rectangle hole for example, its width W satisfies d<W<2d and its length L satisfies dxn+X, d is the diameter of a single wire, n is the wire quantity, and X is arranged wire margin. Moreover, the end faces of theoutlet hole 117 and thewire groove 113 may have a distance K, or the outlet hole is formed on the end face of thewire groove 113, and it is not limited thereto. -
FIG. 2A is a perspective schematic diagram showing a fan frame module according to the second embodiment of the invention, andFIG. 2B is an exploded view of the fan frame module inFIG. 2A . Referring toFIG. 2A andFIG. 2B , in the embodiment, theframe 11 a of the fan frame module 1 a does not have the wire-guidingstructure 116 in the previous embodiment. The length of the wire-stoppingstructure 12 a is equal to the length of thewire groove 113 a. Therefore, in addition to completely covering thewire groove 113 a, the wire-stoppingstructure 12 a may further cover and shield the outlet hole 117 (as shown inFIG. 1H ) so as to avoid the air leak occurring in the outlet hole of the conventional fan and improve characteristics of the air pressure and air volume as shown inFIG. 2C . As to assembly, the wire-stoppingstructure 12 a may be install on theframe 11 a by fastening like the first embodiment, or it may be placed in from one end of thewire groove 113 a and then slid up to a desire location. -
FIG. 3A is a perspective schematic diagram showing a fan frame module according to the third embodiment of the invention, andFIG. 3B is an exploded view of the fan frame module inFIG. 3A . Referring toFIG. 3A , this embodiment is similar to the first embodiment mentioned above. But the difference is that in this embodiment, the wire-stoppingstructure 12 b of thefan frame module 1 b pivots on a pivot S at thefastening portion 114 b. In details, corresponding through holes are formed respectively on the wire-stoppingstructure 12 b and thefastening portion 114 b, so the pivot S can pass through these through holes and the wire-stoppingstructure 12 b and thefastening portion 114 b are pivoted on it. As a result, the wire-stoppingstructure 12 b may be opened or closed with respect to the pivot S as the axis, and it is more difficult to separate the wire-stoppingstructure 12 b and theframe 11. Alternatively, the wire-stoppingstructure 12 b may pivot on the pivot S at thepositioning portion 115, and it is not limited thereto. -
FIG. 4A is a perspective schematic diagram showing a fan frame module according to the fourth embodiment of the invention,FIG. 4B is an exploded view of the fan frame module inFIG. 4A , andFIG. 4C is a schematic diagram showing the assembly process of the fan frame module inFIG. 4A . Referring toFIG. 4A ,FIG. 4B andFIG. 4C , thefan frame module 2 includes theframe 21 and the wire-stoppingstructure 22. Theframe 21 includes theouter wall 211, thewire groove 212, thefastening portion 213 and thepositioning portion 214. The difference between this embodiment and the previous embodiments is that thefastening portion 213 is an indentation, thefirst combination portion 221 of the wire-stoppingstructure 22 is a protruding block, and thefirst combination portion 221 engages with the indentation (the fastening portion 213). Furthermore, the wire-stoppingstructure 22 is roughly like a rectangle board, and it has thefirst combination portion 221 which extends from its longitudinal side corresponding to thefastening portion 213. The extension direction of thefirst combination portion 221 is not coplanar with the board. As a result, the wire-stoppingstructure 22 engages with the indentation (the fastening portion 213) by thefirst combination portion 221 to fix above thewire groove 212 and to cover thewire groove 212. - When assembling the wire-stopping
structure 22, referring toFIG. 4C , thefirst combination portion 221 of the wire-stoppingstructure 22 may correspondingly abut thefastening portion 213 first. The abutted point acts as the pivot to rotate the wire-stoppingstructure 22 toward thewire groove 212. Then, the wire-stoppingstructure 22 is pushed in underneath thepositioning portion 214. At the moment, the wire-stoppingstructure 22 is fixed by thefastening portion 213 and thepositioning portion 214 and covers thewire groove 212. As a result, the wire in thewire groove 212 would not protrude from theouter wall 211 so as to ensure that the wire w in thewire groove 113 would not protrude from theouter wall 111 so as to ensure that the wire would not interfere with external elements or wear. Thus, it is easier to install the fan module. - Moreover, referring to
FIG. 4D , it is a lateral view showing the wire-stoppingstructure 22 of the fan frame module inFIG. 4A . Thefirst combination portion 221 may have abend 2211 at its end to form a hook-like structure. The indentation (the fastening portion 213) may have a notch. When thefirst combination portion 221 engages with the indentation (the fastening portion 213), the hook-like structure may pass through the notch and hooks a portion of the frame at the notch. Therefore, the wire-stoppingstructure 22 can further firmly cover thewire groove 212 and it as well as theframe 21 would not be separated. Besides, the hook-like structure may be formed by the protruding block disposed near the end of thefirst combination portion 221, and it is not limited thereto. Alternatively, the hook-like structure of thefirst combination portion 221 is optional, the fixing may be achieved by merely simple concave-convex engagement or tight fit. -

Referring toFIG. 5A ,FIG. 5B andFIG. 5C , this embodiment is similar to the previous third embodiment. The difference is that in the embodiment, thepositioning portion 214 a is another indentation, thesecond combination portion 222 of the wire-stoppingstructure 22 a is a protruding block. These protruding blocks (thefirst combination portion 221 and the second combination portion 222) respectively engage with these indentations (thefastening portion 213 and thepositioning portion 214 a), so the wire-stoppingstructure 22 a can firmly cover thewire groove 212 and it as well as theframe 21 would not be separated. -

In the embodiment, thefastening portion 311 is located at one end of thewire groove 312, thefastening portion 311 has afastening groove 3111, and thefirst combination portion 321 of the wire-stoppingstructure 32 engages with thefastening groove 3111. Here, the wire-stoppingstructure 32 is like an upside-down U shape. When assembling, the opening of the upside-down U shape corresponds to thefastening portion 311 and the wire-stoppingstructure 32 is disposed in thewire groove 312. Then thefirst combination portion 321 exposed from thewire groove 312 is pushed to thefastening groove 3111 and the assembly is thus completed. - In the embodiment, the
positioning portion 313 is located in thewire groove 312 near the central section to interfere with the wire-stoppingstructure 32 so the wire-stoppingstructure 32 is located within thewire groove 312 and not exposed from theouter wall 314. As a result, the wire in thewire groove 312 would not protrude from theouter wall 314, so it would not interfere with external elements or wear. Thus, it is easier to install the fan module. -

In the embodiment, thefastening portion 511 and thepositioning portion 512 of theframe 51 are chutes and the wire-stoppingstructure 52 slides in these chutes (thefastening portion 511 and the positioning portion 512), so the wire-stoppingstructure 52 is held and fixed to the outer wall and not exposed from theouter wall 514. Thus, the wire in thewire groove 513 would not protrude from theouter wall 514, so it would not interfere with external elements or wear. Thus, it is easier to install the fan module. - A fan module including a frame, a wire-stopping structure and an impeller is also disclosed. The frame includes an outer wall, a wire groove, at least one fastening portion and at least one positioning portion. The outer wall is sequentially divided into a first side section, a first mid section, a central section, a second mid section and a second side section in a first direction. The extension direction of the major axis of the central section is parallel to the central axis of the frame, and the first direction is perpendicular to extension direction of the major axis of the central section. The wire groove is formed on the first mid section to accommodate at least one wire. The fastening portion is disposed on one side of the wire groove in the first direction. The positioning portion is disposed on the other side of the wire groove in the first direction. The wire-stopping structure is held by the fastening portion and the positioning portion and fixed to the outer wall. The impeller is disposed in the frame. Because technique features and the mutual relationships of the frame and the wire-stopping structure have been descripted in the previous embodiments, they are not repeated here.
- It is noted that in all embodiments, the variation of each element, component or unit could be mutually applied to any embodiments, and they are not only limited to the embodiments mentioned above.
- In summary, as to the fan frame module and the fan module, because the wire-stopping structure covers the wire groove of the frame, the wire in the wire groove would not protrude from the outer wall. Thus, the wire would not interfere with external elements or wear, and it is easier to install the fan module. In some embodiments, the wire-stopping structure may further cover and shield the outlet hole of the frame so as to avoid the air leak occurring in the outlet hole of the conventional fan and improve characteristics of the air pressure and air volume.
- Although the invention has been described with reference to specific embodiments, this description is not meant to be construed in a limiting sense. Various modifications of the disclosed embodiments, as well as alternative embodiments, will be apparent to persons skilled in the art. It is, therefore, contemplated that the appended claims will cover all modifications that fall within the true scope of the invention.
