[0027] Example

[0028] The embodiment of the present application provides a heat dissipation device 1, which can be used in electronic devices such as projectors, televisions, and light source devices. The heat dissipation device 1 can be fixed to the electronic device, and the fixing method between the bracket and the electronic device includes but is not limited to thread fixing, riveting, welding, etc., which can be set according to the specific parameters of the electronic device, the use environment, etc.

[0029] See also Figure 1 The heat dissipation device 1 may include a bracket 10, an elastic member 20 and a fan 30. The bracket 10 may enclose an installation space 11, and the installation space 11 has an opening 111. The bracket 10 is provided with a mounting hole 12, and the mounting hole 12 is connected to the installation space 11. The elastic member 20 extends into the mounting hole 12, and at least a portion of the elastic member 20 extends into the installation space 11. The fan 30 has a slot 33, and the fan 30 is movably installed in the bracket 10. In a specific embodiment, the fan 30 is slidably assembled on the bracket 10, and during the assembly process of the fan 30, the assembly direction of the fan 30 is as follows: Figure 1 As shown by the dotted arrow, the fan 30 slides into the installation space 11 along the opening 111. When the fan 30 slides to the installation hole 12, the surface of the fan 30 will force the elastic member 20 to deform so that the fan 30 can pass smoothly. When the fan 30 continues to slide to the specified position and the slot 33 corresponds to the installation hole 12, the elastic member 20 can be embedded in the slot 33, the elastic member 20 returns to its original state, and the elastic member 20 is embedded in the slot 33. The elastic member 20 can abut against the slot wall of the slot 33 so that the bracket 10 and the fan 30 are relatively fixed. Among them, the specified position can be the installation position of the fan 30 in the bracket 10, and the installation position can be selected according to the specific fan 30 and the bracket 10. And when the fan 30 needs to be replaced or maintained later, the elastic member 20 can be moved to deform the elastic member 20. The deformed elastic member 20 can be separated from the slot 33, and then the fan 30 can be easily pushed out of the bracket 10. The elastic member 20 can ensure the firmness of the connection between the fan 30 and the bracket 10 , and facilitate the installation and replacement of the fan 30 , effectively improving the stability and reliability of the heat dissipation device 1 .

[0030] It is understandable that the fan 30 will vibrate when working, and the fan 30 and the bracket 10 are prone to collision. The elastic member 20 of the present application can limit the relative position between the fan 30 and the bracket 10, and can also reduce the collision effect between the fan 30 and the bracket 10, thereby improving the service life of the heat dissipation device 1.

[0031] In this example, please continue to refer to Figure 1, the bracket 10 can be a metal bracket or the like. For example, the bracket 10 can be a stainless steel bracket, which has a certain structural strength and is corrosion-resistant, and can further improve the service life of the bracket 10. The installation space 11 can be arranged opposite to the fan 30, and the bracket 10 can protect the fan 30 and improve the protection performance of the fan 30. Exemplarily, the shape of the installation space 11 is consistent with the shape of the fan 30. For example, the fan 30 is a cubic structure, and the installation space 11 can also be a cube. The volume of the installation space 11 can be the same as the volume of one or more fans 30, so that one or more fans 30 can be smoothly installed in the installation space 11. The gap between the fan 30 and the bracket 10 can be reduced, and the impact between the fan 30 and the bracket 10 can be weakened. The volume of the bracket 10 can also be reduced so that the heat dissipation device 1 can be adapted to small-volume electronic devices.

[0032] In this example, please continue to refer to Figure 1 , the elastic member 20 can be made of metal, for example, the elastic member 20 can be made of stainless steel, spring steel and other materials. This embodiment does not limit the material of the elastic member 20, and it can be selected according to the implementation scenario of the heat dissipation device 1, the strength of the elastic member 20, etc. In addition, the thickness of the elastic member 20 of the present application can be 0.2mm-0.8mm. It can avoid the elastic member 20 being too thin and the structural strength being low, thereby ensuring the structural strength and service life of the elastic member 20. It can also avoid the elastic member 20 being too thick and making it difficult to drive the elastic member 20 to deform. The difficulty of installing the fan 30 can be reduced, and the installation efficiency and service life of the fan 30 can be improved.

[0033] See also Figure 2 as well as Figure 3 , the elastic member 20 may include a first end 21 and a second end 22 relative to each other. The first end 21 is connected to the bracket 10. Exemplarily, the first end 21 may be detachably connected to the bracket 10, such as by threaded connection, snap connection, etc., which is not limited in this embodiment. Further, the first end 21 is threadedly connected to the bracket 10, the first end 21 is provided with a through hole, and the bracket 10 is provided with a threaded hole. Fasteners such as screws may be inserted into the through hole and locked in the threaded hole so that the elastic member 20 can be relatively fixed to the bracket 10. When the elastic member 20 is subsequently worn, the detachable connection between the elastic member 20 and the bracket 10 can facilitate replacement or maintenance. There is no need to replace the bracket 10 at the same time, reducing maintenance costs. When replacing the elastic member 20, there is no need to disassemble the bracket 10 together, reducing the difficulty of maintaining the elastic member 20.

[0034] The second end 22 can extend into the mounting hole 12, and at least part of the second end 22 extends into the mounting space 11. When the fan 30 is installed in the mounting space 11, the slot 33 corresponds to the mounting hole 12, and the second end 22 can be embedded in the slot 33. The second end 22 can abut against the inner wall of the slot 33 to limit the movement of the fan 30 so that the fan 30 can be relatively fixed to the bracket 10. The length and relative angle of the second end 22 can be selected and designed according to the relative position relationship between the elastic member 20 and the fan 30, the matching mode between the slot 33 and the elastic member 20, etc. Exemplarily, the second end 22 can be tilted relative to the first end 21 in a direction away from the opening 111. Because the fan 30 slides into the mounting space 11 through the opening 111, the sliding direction of the fan 30 is opposite to the opening direction of the opening 111, that is, the sliding direction of the fan 30 is from the first end 21 to the second end 22. When the fan 30 slides to the mounting hole 12, one end of the fan 30 close to the bracket 10 abuts against the second end 22 and can form an angle with the second end 22. The fan 30 continues to slide, and the fan 30 can force the second end 22 to deform until the second end 22 is parallel to the first end 21, and one end of the fan 30 smoothly passes through the mounting hole 12. The deformation amount of the second end 22 is related to the inclination angle of the second end 22, and the angle between the first end and the second end can be reduced to make the deformation amount of the second end 22 smaller when the fan 30 passes, so that the fan 30 can be easily installed in the mounting space 11.

[0035] In a more specific embodiment, see Figure 3 as well as Figure 4, the second end 22 may include a first connection end 221 and a second connection end 222. One end of the first connection end 221 is connected to the first end 21, and the other end is bent toward the inside of the mounting hole 12. One end of the second connection end 222 is connected to the end of the first connection end 221 away from the first end 21, and the other end is bent toward the side away from the bracket 10. The first connection end 221 and the second connection end 222 form a roughly "V"-shaped structure. Exemplarily, during the installation process of the fan 30, the first connection end 221 may first abut against the surface of the fan 30, and the first connection end 221 is inclined relative to the surface of the fan 30. Compared with the setting in which the first connection end 221 is perpendicular to the surface of the fan 30, the deformation of the first connection end 221 of this embodiment is smaller, which can avoid the deformation of the elastic member 20 being too large to increase the difficulty of installing the fan 30. In addition, the smaller deformation can also reduce the metal fatigue caused by the deformation of the elastic member 20 and increase the service life of the elastic member 20. When the second end 22 is embedded in the mounting hole 12, the first connection end 221 and the second connection end 222 can respectively abut against the two opposite inner walls of the slot 33, so that the elastic member 20 can limit the fan 30 from sliding into or out of the mounting space 11. In addition, the "V"-shaped structure can provide a certain pressure, which can force the fan 30 to squeeze the bracket 10 in the direction away from the elastic member 20, thereby limiting the movement of the fan 30 in the direction toward or away from the elastic member 20. During the disassembly process of the fan 30. By toggling the second connection end 222, the second connection end 222 can drive the first connection end 221 and the first end 21 to deform together, so that the elastic member 20 is out of the range of the slot 33. The fan 30 can be easily taken out, thereby improving the assembly efficiency of the heat dissipation device 1.

[0036] Preferably, see Figure 5 The first end 21 can be mounted on the surface of the bracket 10, and the extension direction of the first end 21 can be the same as the direction of the opening 111, so that the surface of the fan 30 and the extension direction of the first end 21 are parallel to each other. Figure 5 As shown by the angle a in , the inclination angle of the first connection end 221 of this embodiment relative to the extension direction of the first end 21 may be an acute angle. Further, the inclination angle of the first connection end 221 relative to the extension direction of the first end 21 may be less than 60°, that is, the inclination angle of the first connection end 221 relative to the first end 21 may be greater than 120°, and thus the angle between the first connection end 221 and the surface of the fan 30 is less than 60°. The setting of the inclination angle less than 60° can reduce the maximum deformation of the first connection end 221 during the installation of the fan 30, thereby reducing the difficulty of installing the fan 30.

[0037] In another embodiment, please refer to Figure 5 ,like Figure 5As shown in the angle b in the figure, the inclination angle of the second connection end 222 relative to the extension direction of the first end 21 can be greater than 80° and less than 90°. Since the fan is pushed by gravity to deform the second connection end 222, the angle b is greater than 80 degrees, which can avoid the risk of the elastic member 20 failing to hold the fan 30 due to the excessive inclination angle of the second connection end 222, thereby causing the fan 30 to fall. When the angle b is less than 90 degrees, the risk of the second connection end 222 and the fan 30 being matched at a negative angle, thereby preventing the fan 30 from being disassembled, can be avoided.

[0038] Among them, the specific parameters can be adjusted according to implementation requirements and are not limited in this embodiment.

[0039] In another embodiment, see Figure 6 , in order to further improve the production efficiency of the heat dissipation device 1 and simplify the structure of the heat dissipation device 1. The elastic member 20 can be integrally formed with the bracket 10 by die stamping or the like. Furthermore, the blank of the bracket 10 can be stamped to form the elastic member 20 and the mounting hole 12 at the corresponding position of the blank. In one step, the opening of the mounting hole 12 and the installation of the elastic member 20 are completed, which greatly improves the production efficiency of the heat dissipation device 1. Exemplarily, stamping can be performed at a specified position of the bracket 10, and the wall of the bracket 10 is bent toward the installation space 11 to form the elastic member 20. The structure of the elastic member 20 can be changed by stamping with a stamping die of different structures, for example, the wall can be stamped toward the installation space 11, and only the wall of the bracket 10 is bent toward the installation space 11, so that the elastic member 20 with a certain angle relative to the wall can be formed. Or by stamping in a direction away from the outside of the installation space 11 by the die, the elastic member 20 can be formed into a reciprocating bending structure. The mounting hole 12 is formed at the corresponding position, that is, the mounting hole 12 is opened and the elastic member 20 is installed. The production efficiency of the heat sink 1 can be effectively improved, and the simplified structural setting of the heat sink 1 can help improve the reliability of the heat sink 1. The designated position is the opening position of the mounting hole 12.

[0040] In this application, please continue to refer to Figure 1 The fan 30 may include a frame 31 and blades 32, wherein the frame 31 has a driving space 311, and the blades 32 are installed in the driving space 311, and the blades 32 can be rotatably arranged relative to the frame 31. Furthermore, the fan 30 may also include a driving device, and the driving device is installed in the driving space 311. The blades 32 can be installed on the frame 31 through the driving device, and the blades 32 can be arranged on the output shaft of the driving device. The driving device starts to rotate when it is powered on, thereby driving the blades 32 to rotate, and an airflow can be formed in the driving space 311. The airflow flows to the electronic device, which can dissipate the hot air of the electronic device, so as to take the heat away from the electronic device and achieve the heat dissipation effect.

[0041] It is understandable that the driving direction of the fan blade 32 for the airflow can be changed by changing the rotation direction of the driving device or the tilt direction of the fan blade 32. Furthermore, the driving direction can also be from the second vent to the first vent, and the electronic device can also be arranged on the side of the first vent away from the second vent.

[0042] In one embodiment, please refer to Figure 1 as well as Figure 2 , the slot 33 may be provided in the frame 31, and the direction in which the slot 33 is provided may be the same as the axis of rotation of the fan blade 32. The bracket 10 may be provided with a first mounting plate 13 and a second mounting plate 14 relative to each other, and the frame 31 may be embedded between the first mounting plate 13 and the second mounting plate 14. The mounting hole 12 is provided in the first mounting plate 13, and the mounting hole 12 may penetrate the first mounting plate 13. The elastic member 20 is connected to the first mounting plate 13, and the elastic member 20 extends into the installation space 11 through the mounting hole 12 of the first mounting plate 13. The surface of the fan 30 on which the slot 33 is provided may be provided corresponding to the first mounting plate 13, so that the slot 33 can correspond to the mounting hole 12, thereby ensuring that the elastic member 20 can be embedded in the slot 33, and improving the installation effect of the fan 30.

[0043] In a more specific implementation, please continue to refer to Figure 2 , the frame 31 may include a first surface 311 and a second surface 312, the surface of the first mounting plate 13 away from the second mounting plate 14 is the first mounting surface 131, and the surface of the second mounting plate 14 away from the first mounting plate 13 is the second mounting surface 141. When the fan 30 is installed in the installation space 11, the first surface 311 is arranged corresponding to the first mounting surface 131, and the second surface 312 is arranged corresponding to the second mounting surface 141. The first mounting surface 131 is provided with a first vent, and the second mounting surface 141 is provided with a second vent. When the elastic member 20 and the card slot 33 cooperate with each other, the first vent and the second vent are connected to the driving space 311. Exemplarily, the axis of the driving device can be coaxially arranged with the first vent and the second vent, and the fan blade 32 drives the airflow to flow from the first vent toward the second vent. The electronic device can be arranged on the side of the second vent away from the first vent, so that the airflow can flow through the electronic device to take away the heat of the electronic device.

[0044] In one embodiment, please refer to Figure 2, the number of mounting holes 12 can be multiple, and the multiple mounting holes 12 are arranged at intervals. There can be multiple elastic members 20, and the multiple elastic members 20 are arranged one by one with the multiple mounting holes 12. Exemplarily, the multiple elastic members 20 can abut against the surface of the frame 31, and under the influence of elastic force, the multiple elastic members 20 can be clamped on the fan 30. The installation effect between the fan 30 and the bracket 10 can be guaranteed. Furthermore, the multiple mounting holes 12 can be respectively arranged on the first mounting plate 13 and the second mounting plate 14, and the mounting holes 12 of the first mounting plate 13 and the mounting holes 12 of the second mounting plate 14 are arranged correspondingly. The fan 30 is placed in a manner in which any one surface faces upward, and there is no need to distinguish the surface of the fan 30. This solves the problem that the slot 33 of the fan 30 and the elastic member 20 are not aligned due to the placement direction of the fan 30.

[0045] In another embodiment, the number of the slots 33 may be multiple, and the multiple elastic members 20 are arranged in a one-to-one correspondence with the multiple slots 33. This ensures that the multiple elastic members 20 can be embedded in the multiple slots 33 at the same time, avoids damage to a single elastic member 20 affecting the installation effect of the fan 30, and reduces the failure rate of the heat dissipation device 1.

[0046] In order to reduce the impact or vibration between the fan 30 and the bracket 10, the frame 31 in this embodiment is provided with a buffer layer 313, and the buffer layer 313 can be made of a flexible material. For example, the buffer layer 313 can be a silicone layer, and the silicone layer has a certain buffering effect. The buffer layer 313 can be arranged between the frame 31 and the bracket 10, and the buffer layer 313 can reduce the impact between the frame 31 and the bracket 10. Further, the buffer layer 313 of the present application can be arranged on the first mounting surface 131 and the second mounting surface 141, and the buffer layer 313 can reduce the impact between the fan 30 and the first mounting plate 13 and the second mounting plate 14, etc., to ensure the service life of the fan 30. In one embodiment, the buffer layer 313 can be provided with a through hole, and the through hole is arranged corresponding to the card slot 33, and the elastic member 20 can slide along the surface of the buffer layer 313. In addition, the elastic member 20 can extend into the card slot 33 along the through hole to prevent the buffer layer 313 from affecting the elastic member 20 from being embedded in the card slot 33, thereby ensuring the installation effect of the fan 30.

[0047] In the heat dissipation device 1 provided in the embodiment of the present application, the fan 30 can slide into the installation space 11 along the opening 111, and the second end 22 of the elastic member 20 extends into the installation hole 12 of the bracket 10. When the fan 30 slides to a predetermined position, the slot 33 corresponds to the installation hole 12, and the second end 22 is embedded in the slot 33, thereby completing the installation of the fan 30, and the installation method is simple and fast. In addition, the elastic member 20 and the slot 33 cooperate to improve the connectivity between the fan 30 and the bracket 10, thereby ensuring the practicality and reliability of the heat dissipation device 1.

[0048] The above implementation modes are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned implementation modes, a person skilled in the art should understand that the technical solutions described in the aforementioned implementation modes can still be modified, or some of the technical features can be replaced by equivalents. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various implementation modes of the present application, and should all be included in the protection scope of the present application.
