Specific embodiments

[0040] The following combines the drawings to describe in detail the specific embodiments of the present utility model, but it should be understood that the protection scope of the present utility model is not limited by the specific embodiments.

[0041] Unless otherwise clearly stated, in the whole specification and claims, the term "comprising" or its variations such as "including" or "having" etc. will be understood to include the stated elements or components, without excluding other elements or other components.

[0042] Such as Figures 1 to 11As shown, an installation structure of a heat dissipation fan and a fin module according to a preferred embodiment of the present utility model includes a fan bracket 2 and a fin module bracket 4; the fan bracket 2 is disposed on one side of the fan assembly 1 close to the heat dissipation fin module 3; the fin module bracket 4 is disposed on one side of the heat dissipation fin module 3 close to the fan assembly 1; wherein the fan bracket 2 and the fin module bracket 4 are connected by an elastic member to achieve quick sliding snap connection. Among them, the so-called sliding is the relative sliding between the fan bracket 2 and the fin module bracket 4, and the so-called snap connection is that the fan bracket 2 is snapped with the fin module bracket 4 through the elastic member.

[0043] In some embodiments, Figures 1 to 11 The embodiments illustrated are all double towers (double fans and double heat dissipation fins), however, the present utility model is not limited thereto. This solution can mainly be used in the field of air-cooled radiators, and can be used as long as there are fans and fin groups, and it is not limited to being applied to single towers, double towers or other structures of radiators.

[0044] In some embodiments, Figures 1 to 11 The installation structure described in the embodiments mainly includes two components, namely the fan bracket 2 and the fin module bracket 4. An elastic member is provided on the fan bracket 2, and a snap groove 401 is provided on the fin module bracket 4. The fan bracket 2 and the fin module bracket 4 are snap-connected through the elastic member and the snap groove 401. However, the present utility model is not limited thereto, because it can also include that an elastic member is provided on the fan bracket 2 and no snap groove 401 is provided on the fin module bracket, or the snap groove 401 is included in the elastic member, etc., so that quick snap connection can also be achieved.

[0045] As Figures 12 to 14 shown, also referring to Figure 4 , in some embodiments, an elastic member is provided on the fan bracket 2; a plurality of snap grooves 401 are provided on the fin module bracket 4; the fan bracket 2 relies on the elastic member and the snap grooves 401 of the fin module bracket 4 to form a sliding snap connection with the fin module bracket 4. In some cases, without setting grooves, the fixing function can basically be achieved only by the static friction between the elastic member and the fin module bracket 4, but adding grooves can increase the stability of the connection.

[0046] In some embodiments, the fan bracket and the fin module bracket of this embodiment rely on the elastic member and the snap groove to achieve quick connection, but the present utility model is not limited thereto, and quick connection can also be achieved through other installation structures, and the so-called installation structure can adopt the prior art.

[0047] Please refer to Figure 4 and Figures 12 to 14, in some embodiments, the elastic member includes an elastic connection member 206 and a fixed elastic piece 207; the elastic connection member 206 is detachably disposed on the fan bracket 2, and the elastic connection member 206 includes an elastic member mounting portion 2061; the fixed elastic piece 207 is detachably disposed at the elastic member mounting portion 2061, and the fixed elastic piece 207 is bent outward to form an elastic protrusion; by fitting the elastic protrusion into the engaging groove 401, a quick sliding snap connection between the fan bracket 2 and the fin module bracket 4 is achieved.

[0048] As Figures 15 to 17 shown, also referring to Figure 4 , in some embodiments, the elastic member includes an elastic connection member 206 and an elastic bead 207'; the elastic connection member 206 is detachably disposed on the fan bracket 2, and the elastic connection member 206 includes an elastic member mounting portion 2061'; the elastic bead 207' is detachably disposed at the elastic member mounting portion 2061'; wherein the elastic bead 207' can be fitted with an engaging groove 401, and a quick sliding snap connection between the fan bracket 2 and the fin module bracket 4 is achieved.

[0049] In some embodiments, Figures 15 to 17 The difference between the embodiment and Figures 12 to 14 is that the fixed elastic piece 207 is replaced with an elastic bead 207', and the groove shape is only exemplary. For example, the engaging groove corresponding to the fixed elastic piece can be in the shape of Figure 13 , or can be in the shape of Figure 16 , and vice versa. The groove corresponding to the elastic bead can also be in the shape of Figure 13 or Figure 16 shape. The structures of the elastic connection member 206 and the elastic bead 207' can both adopt the prior art, and any structure that satisfies the quick snap connection can be used, without limitation here.

[0050] Please refer to Figure 12 , in some embodiments, the transverse cross-section of the fan bracket 2 is in an L shape. The fan bracket 2 includes a connection hole 201, a guiding rib 203, and a plurality of connection member mounting portions 202; the connection hole 201 is disposed at both ends of the long side of the L shape, and the connection hole 201 is used to connect and fix the fan assembly 1 through a fixing screw 208; the guiding rib 203 is disposed on the short side of the L shape; the plurality of connection member mounting portions 202 are disposed on the transverse side of the L shape, and the connection member mounting portions 202 are used to dispose the elastic member.

[0051] In some embodiments, the fin module bracket 4 includes a connecting portion 403 and a guiding groove 402; the connecting portion 403 is disposed at both ends of the fin module bracket 4, and mounting holes 404 are provided on the connecting portion 403 for fixedly connecting with the heat dissipation fin module 3 through bolts; the guiding groove 402 is disposed along the length direction of the fin module bracket 4 and is arranged in parallel with a plurality of engaging grooves 401, and one end of the guiding groove 402 is provided with an opening; wherein the guiding groove 402 is used for guiding the insertion of the convex rib 203, so as to realize the sliding connection between the fan bracket 2 and the fin module bracket 4.

[0052] In some embodiments, the connection between the fan assembly and the heat dissipation fin assembly is achieved through two opposite mounting mechanisms. Please refer to Figure 3 , the transverse cross-section of the fan bracket 2 is in an L-shaped structure, forming a bayonet structure as shown in Figure 20 for cooperation with the fin module bracket 4. That is to say, the guiding convex ribs 203 of the fan bracket 2 provided at the two side edges of the fan assembly together form a bayonet with the guiding convex ribs facing each other on both sides. Conversely, the guiding grooves 402 of the fin module bracket 4 provided at the two side edges of the heat dissipation fin assembly together form a card slot with the guiding grooves facing away from each other. The two opposite guiding convex ribs 203 are simultaneously inserted into the two guiding grooves 402 facing away from each other to achieve a sliding snap connection. In addition to ensuring the quick installation of the fan assembly and the heat dissipation fin assembly, it avoids the loosening of the connection between the fan assembly and the heat dissipation fin assembly due to fan vibration, and further ensures the stable connection between the fan assembly and the heat dissipation fin assembly.

[0053] Wherein, the so-called sliding is the sliding of the guiding convex rib 203 along the guiding groove 402, and the so-called snap fit is the snap fit between the elastic member and the engaging groove 401. It should be noted that the above-mentioned L-shaped structure of the transverse cross-section of the fan bracket 2 is only one of the embodiments, and its corresponding specific structure can be set according to needs, and this specification does not limit this.

[0054] However, the present invention is not limited thereto. The fan bracket 2 actually has several functions. For example, but not limited to, the connection holes 201 on the long side can realize the connection and fixing function with the fan. Of course, the setting position of the connection holes 201 is not limited to being set at both ends, and can also be set at other positions as long as the fixed connection with the fan assembly can be realized; the guiding convex rib 203 formed by the short side can realize the guiding and limiting function with the guiding groove 402 of the fin module bracket 4; and the elastic member provided on the transverse side and the plurality of engaging grooves 401 on the fin module bracket 4 can realize the quick elastic snap fit function. Therefore, the L-shaped structure of the fan bracket 2 is not the only structure, and the combination of its long side, short side and transverse side can also be other forms, such as, but not limited to, a Π-shaped structure, as long as the above functions can be completed.

[0055] Please refer toFigure 12 and Figure 20 In some embodiments, the so-called long side, short side, and transverse side are defined based on the L-shaped cross-section of the fan bracket 2. The long side is the relatively longer side with the connection holes 201 provided thereon, and the short side is the relatively shorter side, which is the side where the guiding convex rib is formed. The transverse side is the section connecting the long side and the short side, and the connecting member mounting portion 202 is provided at the transverse side.

[0056] Please refer to Figure 12 In some embodiments, a convex rib chamfer 204 is provided at one end of the guiding convex rib 203.

[0057] Please refer to Figure 14 In some embodiments, a guiding bevel 405 is provided at the open end of the guiding groove 402.

[0058] In some embodiments, the purposes of providing the convex rib chamfer 204 and the guiding bevel 405 are both to enable quick snap-fitting.

[0059] Please refer to Figure 12 and Figure 14 In some embodiments, the fan bracket 2 may further include an error correction flap 205. The error correction flap 205 is provided at both ends of the connecting edge between the long side and the transverse side. The error correction flap 205 is perpendicular to the long side and extends away from the transverse side. The main function of the error correction flap 205 is that when installing the fan bracket 2, the error correction flap 205 can abut against the edge of the fan assembly 1, so that the connection holes 201 can be quickly aligned with the mounting holes of the fan assembly 1, and it also serves to prevent the fan bracket 2 from being installed in the wrong direction.

[0060] Please refer to Figures 12 to 13 and Figure 15 and Figure 16 In some embodiments, both the fan bracket 2 and the fin module bracket 4 can be formed by metal or non-metal casting. The fan bracket 2 can also be formed by stamping with a steel plate mold. For example, the connecting member mounting portion 202 can be a snap-fitting position directly stamped out. The elastic connecting member 206 can also be a snap-fitting position where the elastic member mounting portion 2061 is stamped out on a strip-shaped steel plate. The fixing spring piece 207 can be made of a steel plate that is thinner than the elastic connecting member 206 and has better elasticity. It is bent and snap-fitted at the elastic member mounting portion 2061, and the outward protrusion formed by bending fits with the snap-fitting groove 401 to achieve the quick snap-fitting function.

[0061] Such as Figures 18 to 19As shown, in some embodiments, the elastic component includes a fixed elastic piece 207. The fixed elastic piece 207 is integrally formed on the fan bracket 2. The fixed elastic piece 207 bends outward to form an elastic protrusion. The elastic protrusion can fit into a clamping groove 401, and realize the quick sliding clamping connection between the fan bracket 2 and the fin module bracket 4. The integrally formed fixed elastic piece 207 can be directly cast, or can be formed by stamping with a steel plate mold. Please refer to Figure 19 , the fixed elastic piece 207 can be connected at one end and disconnected at the other end, or both ends are connected (not shown), and the elasticity of the metal of the present application is utilized to form an outward elastic protrusion. Or such an integrally formed protrusion of the present application does not have elasticity, and an elastic gasket-like component is arranged in the clamping groove 401 to realize elastic clamping connection.

[0062] In some embodiments, Figures 18 to 19 The advantage of the embodiment is that the manufacturing is relatively simple. However, if the fixed elastic piece 207 is damaged, the entire fan bracket 2 has to be replaced, while Figures 12 to 13 and Figure 15 and Figure 16 The advantage of the embodiment is that if the elastic component is damaged, only the damaged fixed elastic piece 207 or the elastic bead 207' needs to be replaced.

[0063] Please refer to Figures 15 to 17 , in some embodiments, an elastic component is arranged on the fin module bracket 4; a plurality of clamping grooves 401 are arranged on the fan bracket 2; wherein the fin module bracket 4 relies on the elastic component and the clamping grooves 401 of the fan bracket 2 to form a sliding clamping connection with the fan bracket 2. This embodiment expresses that the fixed elastic piece 207 or the elastic bead 207' can also be arranged on the fin module bracket 4, the clamping grooves 401 can also be arranged on the fan bracket 2, or the positions of the fan bracket 2 and the fin module bracket 4 can be swapped.

[0064] Please refer to Figure 2 and Figure 3 , in some embodiments, according to different heat dissipation requirements, the size specifications of the fan assembly and the heat dissipation fin module will also be different. According to the requirements of fan assemblies and heat dissipation fin modules with different size specifications, the size specifications of the fan bracket and the fin module bracket should always be adapted, and the sizes of the guiding ridges and guiding grooves will also change accordingly. Also, as the size increases, for example, the number of fixed elastic pieces, elastic beads, and clamping grooves also needs to be increased accordingly.

[0065] In summary, the installation structure of a heat dissipation fan and a fin module of the present utility model has the following advantages: This solution mainly consists of a fan bracket, a fixing spring piece, and a fin module bracket, etc. Among them, the fan bracket and the fin module bracket can be quickly disassembled and assembled through elastic clamping devices such as the fixing spring piece and the limiting groove; in addition, the elastic clamping device is also designed with a convex rib chamfer, a guiding bevel, and an error correction stop piece, which can facilitate the smooth clamping connection of the elastic clamping device and prevent the misassembly of the fan bracket and the fin module bracket, greatly improving the disassembly and assembly speed of the heat dissipation fan and the fin module.
