Description
Technical Field
The present invention relates to a heat dissipation fan and components thereof, and more particularly, to a series fan frame and a series fan having the same.
Background
Referring to fig. 1, a conventional series fan frame 9 is shown, in which the conventional series fan frame 9 has a lower frame 91 and an upper frame 92 connected in series in an axial direction. The lower frame 91 has a threading opening at one end facing the upper frame 92 and a lower clamping structure 911 at the other end; the upper frame 92 has a threading opening at one end facing the lower frame 91 and an upper clamping structure 921 at the other end. The threading opening of the lower frame 91 is communicated with the threading opening of the upper frame 92, and the conventional series fan frame 9 further has a limiting piece 93 which is shielded outside the two threading openings. The two stator sets installed in the lower frame 91 and the upper frame 92 respectively have a plurality of wires E, which can pass through the two threading openings and be shielded by the limiting plate 93, and then pass through the lower clamping structure 911 or the upper clamping structure 921 together along with the wires E. The plurality of electric wires E may be shielded by a buckle piece 94 combined with the lower frame 91 or the upper frame 92 at a position where the outer circumferential surface of the lower frame 91 or the upper frame 92 extends in the axial direction. An embodiment similar to the prior art series fan frame 9 is disclosed in taiwan patent No. M364400.
Because the plurality of electric wires E pass through the threading openings of the lower frame 91 and the threading openings of the upper frame 92 and are completely threaded toward the upper end or the lower end, the plurality of electric wires E are difficult to form a flat and parallel pattern at the axially extending positions of the outer circumferential surface of the lower frame 91 or the upper frame 92, and the partial electric wires E are in an overlapped convex shape. Therefore, in order to avoid scratching the protruded portions of the wires E during the process of installing the conventional series fan frame 9 to the system, the conventional series fan frame 9 needs to additionally provide the fastening piece 94 to press the wires E, which results in more components of the conventional series fan frame 9 and poor manufacturing cost and assembly efficiency. In addition, if the wires E are not completely pulled, the protruding portions of the wires E even make it difficult for the buckle piece 94 to be combined with the lower frame 91 or the upper frame 92, so that the assembling personnel needs to re-arrange the wires to install the buckle piece 94, and therefore the conventional series fan frame 9 often has a Rework (Rework) problem during assembling, which seriously affects the assembling efficiency.
In view of the above, there is still a need for improvement of the conventional series fan frame.
SUMMERY OF THE UTILITY MODEL
To solve the above problems, an object of the present invention is to provide a series fan frame, which can make the wires penetrating through the fan frame form a flat and parallel configuration.

Detailed Description
In order to make the aforementioned and other objects, features and advantages of the present invention comprehensible, preferred embodiments accompanied with figures are described in detail below:
referring to fig. 2, it is a preferred embodiment of the series fan frame F of the present invention, wherein the series fan frame F includes two frame bodies 1 connected in series in an axial direction.
Referring to fig. 2 and 9, the two frame bodies 1 are not limited to the type disclosed in the drawings of the present embodiment, and the structure of the combination of the two frame bodies is not limited, which can be adjusted by those skilled in the art according to the needs of the application. In this embodiment, the two frame bodies 1 may have substantially similar structures, and each of the two frame bodies 1 may be provided with a stator set S and a fan wheel P; the two stator sets S have a plurality of wires E electrically connected to an external power source, respectively, so that the two fan wheels P can be driven to rotate by the two stator sets S, respectively, and guide the air flow to flow into one of the frames 1 and flow out of the other frame 1. The connection relationship and the operation principle of each frame 1 and the stator set S and the impeller P inside the frame are understood by those skilled in the art, and therefore, the detailed description thereof is omitted.
The two frame bodies 1 have a joint end surface 11, respectively, and the joint end surfaces 11 of the two frame bodies 1 face each other. Each housing 1 has a plurality of slots 12 provided at intervals, and each slot 12 is formed by being recessed from the coupling end surface 11 so that each slot 12 can be opened at the coupling end surface 11. The wire slots 12 can be located at one corner of the frame 1, and are respectively used for the wires E to pass through the frame 1; in other words, each wire slot 12 is used for only one wire E to pass through, so as to form a "one slot and one wire" configuration.
As shown in fig. 4, in detail, the maximum width W1 in each wire slot 12 may be greater than or equal to the wire diameter D of the wire E, so that the portion of the wire E passing through the wire slot 12 is not easily squeezed or scratched. Each wire casing 12 forms an opening 13 on the combining end surface 11, the maximum height H from the inner bottom edge 121 of each wire casing 12 to the combining end surface 11 can be greater than the wire diameter D of the wire E, the minimum width W2 of each wire casing 12 adjacent to the opening 13 can be smaller than the wire diameter D of the wire E, so that the plurality of wires E pulled out from the frame 1 can be respectively penetrated into the corresponding wire casings 12 through different openings 13 with a slight force and stably limited in the wire casing 12, and unless the wire E is pulled with a pulling force exceeding a predetermined value, the wire E penetrating through the wire casing 12 is not easy to be separated from the wire casing 12 through the opening 13. Wherein the maximum width W1 and the maximum height H may each be less than twice the wire diameter D, and twice the maximum height H may be less than three times the wire diameter D; thus, each wire casing 12 can have a proper size, so that each wire casing 12 can be easily molded without causing an excessive influence on the structural strength of the frame body 1.
In addition, the frame 1 forms a wire separation sheet 14 between two adjacent wire slots 12, and in order to ensure that the wire separation sheet 14 has sufficient structural strength and is not easy to break, the minimum width W3 on both sides of the wire separation sheet 14 is selected to be greater than or equal to the maximum width W1 in the adjacent wire slots 12, and the ratio (W3/H) of the minimum width W3 to the maximum height H is about 0.5-0.8. As shown in fig. 3, the thickness T of the wire-separating sheet 14 may be greater than or equal to one-fourth of the minimum width W3.
Referring to fig. 4 again, the present invention does not limit the frame body 1 to form the aforementioned "the minimum width W2 is smaller than the line diameter D"; for example, the two sidewalls 122 of each wire casing 12 are substantially parallel, and an inwardly-tapered portion 123 is formed adjacent to the opening 13, so as to form a portion having the minimum width W2 between the two inwardly-tapered portions 123. Meanwhile, the two retracted portions 123 may be symmetrical (as shown in fig. 4) or asymmetrical; alternatively, in other embodiments, as shown in fig. 6, only one side wall 122 forms an inward-contracting portion 123 adjacent to the opening 13; alternatively, as shown in fig. 7, the width between the two side walls 122 of the wire casing 12 decreases toward the opening 13, so as to form a portion with the minimum width W2 at the opening 13. It should be noted that, referring to fig. 8, the wire casing 12 may not have the aforementioned inward-contracting portion 123.
Referring to fig. 2, the frame body 1 further has an outer end surface 15, and the outer end surface 15 and the coupling end surface 11 are respectively located at two axial ends of the frame body 1. The frame body 1 can be provided with a wire clamping piece 16 near the corner, so as to form a containing groove 17 between the wire clamping piece 16 and the outer circumferential surface C of the frame body 1, the containing groove 17 can form an axial extension range R on the outer circumferential surface C of the frame body 1, and the plurality of wire grooves 12 can be located in the axial extension range R. In addition, as shown in fig. 5, after the two frame bodies 1 are axially connected in series, the openings 13 of the plurality of slots 12 of the two frame bodies 1 may be completely aligned, partially opposed, completely staggered, or the aforementioned comprehensive configuration, and the utility model is not limited thereto, and preferably, the completely aligned configuration is formed.
Referring to fig. 4 and 9, when assembling the series fan G of the present invention, the two stator groups S can be first installed and positioned in the two frame bodies 1, and then the plurality of wires E of the two stator groups S are pulled out of the frame body 1 and placed into the corresponding slots 12 through the opening 13 from the connecting end surface 11. The plurality of electric wires E which penetrate out of the two frame bodies 1 are continuously pulled together towards one of the wire clamping sheets 16 to penetrate out of one of the accommodating grooves 17.
Because the wires E are inserted into the slots 12 in a "slot-to-line" configuration, the wires E can penetrate through the two frames 1 side by side, so that when the wires are aligned toward one end, the wires E can form a flat and side-by-side configuration on the outer circumferential surface C of the frame 1, and the wires E are not easily scratched. In addition, even in the embodiment where the space of the accommodating slot 17 is small, only a part of the electric wires E adjacent to the accommodating slot 17 are overlapped, but can be limited by the wire clamping piece 16, so that the overlapped part of the electric wires E does not protrude out of the wire clamping piece 16.
In summary, the series fan and the series fan frame of the present invention can make the plurality of wires penetrating through the frame body form a flat and parallel configuration, and no additional assembly component is needed to shield the portion of the plurality of wires exposed on the outer circumferential surface of the frame body, so compared with the existing series fan frame, the series fan frame of the present invention has fewer components, which can reduce the manufacturing cost and reduce the assembly steps of the series fan, and after the plurality of wires penetrate through the frame body, the wires do not need to be repeatedly pulled, and the rework problem is hardly generated, which helps to greatly improve the assembly efficiency, and when the series fan is installed in a system or packaged with the series fan, the wires are ensured not to be easily scratched, and the series fan failure rate is reduced.
It should be noted that, in some embodiments of the present invention, after the plurality of wires are passed through the accommodating groove, an adhesive tape such as an acetate cloth may be further used to attach the plurality of wires to the outer circumferential surface of the frame. Thus, even if the overall assembly efficiency is slightly affected, the electric wires can be closer to the outer circumferential surface of the frame body, so that the probability of scratching the electric wires in the assembly or packaging process is reduced; in addition, even if the foreign object touches the position where the electric wire is arranged, the foreign object only touches the adhesive tape and cannot directly touch the electric wire, so that the protection of the electric wire can be improved, and the fault rate of the series fan can be further reduced.
Although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes and modifications can be made by those skilled in the art without departing from the spirit and scope of the utility model.
