[0024] In order to facilitate the understanding of the utility model, the utility model is described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or there can be one or more centered elements therebetween.

The terms "vertical", "horizontal", "left", "right" and similar expressions used in this specification are for illustrative purposes only.

[0025] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by technicians in the technical field of the present invention. The terms used in this specification are only for the purpose of describing specific embodiments and are not used to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more related listed items.

[0026] See also Figure 1 Combined with Figure 2 The cooling fan 1000 includes: a fan body 1, a fixing member 2, a screw connection member 3 and a cooling fin 4, wherein the fan body 1 is movably arranged on the fixing member 2, and the fixing member 2 uses the screw connection member 3 to screw one end of the fixing member 2 to an external device, and the external device refers to a device such as a PCB board on which the cooling fan 1000 needs to be installed; the other end of the fixing member 2 is fixedly connected to the cooling fin 4, thereby ensuring a stable connection of the fixing member 2, and avoiding that when only one end of the fixing member 2 is fixed, the fan body 1 is fixed to the external device through the fixing member 2, and the stability of the connection of the fan body 1 is destroyed due to the working vibration of the fan body 1 or external force.

[0027] For the fan body 1 mentioned above, please refer to Figure 3The fan body 1 is provided with a strip-shaped platform 11, and the fan body 1 also includes a shell 12 and a fan 13, wherein the strip-shaped platform 11 is used to cooperate with the fixing member 2 to achieve fixation; the shell 12 is provided with a receiving cavity 122, an air inlet 123 and an air outlet 124, the air inlet 123 is close to the surface of the heat dissipation element to be cooled, so that the high-temperature gas generated by the heat dissipation element to be cooled can be quickly drawn away by the fan body, and the air outlet 124 is provided on the shell 12 near the heat dissipation fins 4 , and there is another air outlet 124a, the air outlet 124a is arranged on the other surface of the housing 12 opposite to the air inlet 123, forming an air duct from the air inlet 123 to the receiving cavity 122, and then to the air outlet 124a. The air inlet 123 and the air outlet 124 are both connected to the receiving cavity 122, forming another air duct from the air inlet 123 to the receiving cavity 122 to the air outlet 124. The formation of the two air ducts greatly improves the heat dissipation capacity of the fan. The fan 13 is installed in the receiving cavity 122, the housing 12 is extended with an extension piece 121, the extension piece 121 is adjacent to the air outlet 124, and the strip table 11 is arranged on the extension piece 121.

[0028] It can be understood that the material of the fan body 1 includes but is not limited to hard plastic, hard rubber, etc.

[0029] It can be understood that the number of the extension members 121 is two, each of the extension members 121 is provided with a strip platform 11 , and the strip platform 11 is provided on the surfaces of the extension members 121 facing each other.

[0030] For the above-mentioned strip table 11, Figure 4 As shown, the cross-section of the strip-shaped table 11 is in the shape of a runway. The arc portion (not marked) of the runway-shaped strip-shaped table 11 facilitates the rotation of the strip-shaped table 11, and the straight portion (not marked) facilitates the sliding of the strip-shaped table 11.

[0031] In some embodiments, a limiting column 125 is further provided on the outer surface of the shell 12, and the limiting column 125 is located at the end face of the shell 122 opposite to the air outlet. The limiting column 125 is used to abut the external device. The existence of the limiting column leaves a certain space between the cooling fan 1000 and the external device, which facilitates the cooling fan 1000 to be directly installed above the heat dissipation component to be cooled, wherein the heat dissipation component to be cooled is electronic components such as chips and capacitors.

[0032] It can be understood that the number of the limit column is at least one, and the limit column can also extend in the direction away from the external device to form an extension column. When the extension column is used to install the cooling fan 1000 in a movable cavity, the extension column abuts against the inner wall of the cavity to prevent the cooling fan 1000 from shaking.

[0033] It is understandable that the limiting column 125 can also be located on a surface of the shell 122 close to the external device, so as to facilitate the processing of the shell 122 and improve the aesthetics of the heat dissipation fan.

[0034] In some embodiments, see Figure 5 Combined with Figure 6 and Figure 7 The fixing member 2 is provided with a fixing hole 21, and the fixing hole 21 includes a sliding hole 211 and a rotating hole 212. One end of the sliding hole 211 is connected to the rotating hole 212, and the rotating hole 212 is circular in shape. When the length direction of the strip table 11 is the same as the extension direction of the sliding hole 211, as shown in FIG. Figure 6 As shown, the strip table 11 can be inserted into the slide hole 211 and slide along the slide hole 211 to the rotation hole 212. The strip table 11 can rotate in the rotation hole 212, and when the length direction of the strip table 11 is staggered with the extension direction of the slide hole 211, as shown in FIG. Figure 7 As shown, the inner wall of the rotating hole 212 and the strip table 11 cooperate to limit the strip table 11 from sliding from the rotating hole 212 to the sliding hole 211, and the fins of the heat dissipation fins 4 are aligned with the air outlet 124, which is beneficial to the rapid cooling of hot air in the external device.

[0035] It can be understood that the sliding hole 211 provides space for the movement of the strip table 11 of the fan body 1 on the fixing member 2, and the layout direction of the sliding hole 211 limits the movement trajectory of the strip table 11. When the strip table 11 is inserted into the sliding hole 211, it can only reciprocate in the sliding hole 211 along the extension direction of the sliding hole 211. When the strip table 11 moves into the rotating hole 212, the strip table 11 completely falls into the rotating hole 212. After rotating through a certain angle, the inner wall of the rotating hole 212 limits the strip table 11 in the radial direction of the rotating hole 212, so that the strip table 11 can only rotate in the rotating hole 212 but not in the radial direction of the rotating hole 212. Moreover, when the two extending members 121 arranged opposite to each other are respectively inserted into the rotating holes, the extending members 121 and the fixing member 2 cooperate to limit the strip table 11 in the axial direction of the rotating hole 212.

[0036] It is worth noting that the width of the sliding hole 211 is smaller than the diameter of the rotating hole 212, and the width of the sliding hole 211 is equal to or greater than the width of the strip table 11, ensuring that the sliding hole 211 constrains the movement trajectory of the strip table 11 in the sliding hole 211 to prevent the strip table 11 from rotating in the sliding hole 211, and the diameter of the rotating hole 212 is greater than or equal to the length of the strip table 11 to ensure the rotation of the strip table 11 in the rotating hole 212.

[0037] It can be understood that the difference between the width of the sliding hole 211 and the width of the strip table 11 should not be too large to avoid the strip table 11 from shaking when sliding in the sliding hole 211. The difference between the diameter of the rotating hole 212 and the width of the strip table 11 should not be too large to avoid the strip table 11 from shaking when rotating in the rotating hole 212. The specific difference can be set according to actual needs, and no detailed examples are given in this embodiment.

[0038] like Figure 5 As shown, the fixing member 2 also includes a fixing portion 22, a mounting portion 23 and a connecting portion 24, one end of the fixing portion 22 is connected to the mounting portion 23, the connecting portion 24 is connected to the other end of the fixing portion 22, and an angle is formed between the fixing portion 22 and the mounting portion 23, and the angle of the angle is designed according to actual needs, and is preferably 90° in this embodiment. The fixing hole 21 is arranged on the fixing portion 22, that is, the sliding hole 211 and the rotating hole 212 are arranged on the fixing portion 22, the mounting portion 23 is used to be fixed to an external device, and the connecting portion 24 is fixed to the heat sink fin 4.

[0039] In some embodiments, the mounting portion 23 is provided with a through hole 231 , and the screw connection member 3 is used to pass through the through hole 231 and then be screwed to the external device.

[0040] It is worth noting that the connecting portion 24 is not completely fixed on the heat dissipating fins 4 as a whole, and at least a part of the connecting portion 24 is fixed to the heat dissipating fins 4, so that a certain gap is left between the fixing portion 22 and the end face of the heat dissipating fins 4 closest thereto, so that when the strip table 11 slides in the sliding hole 211 and / or when the strip table 11 rotates in the rotating hole 212, no friction will occur between the strip table 11 and the heat dissipating fins 4, thereby avoiding the occurrence of wear of the strip table 11 or the heat dissipating fins 4.

[0041] It can be understood that the fixing methods of the connecting portion 24 and the heat sink fins 4 include but are not limited to welding, gluing, etc. When welding is adopted, the fixing of the connecting portion 24 and the heat sink fins 4 can be made more stable and reliable. When gluing is adopted, the selection of the glue should take into account the heat-resistant characteristics to avoid the glue between the heat sink fins 4 and the connecting portion 24 from falling off due to excessive heat conducted to the heat sink fins 4 by external equipment.

[0042] In some embodiments, the connection portion 24 is perpendicular to the fixing portion 22, the mounting portion 23 is perpendicular to the fixing portion 22, and the connection portion 24 and the mounting portion 23 are respectively located on both sides of the fixing portion 22, and the shape of the fixing member 2 is Z-shaped. The Z-shaped fixing member 2 allows the mounting portion 23 to directly stand on the device to be installed when installing the cooling fan 1000, and the connection portion 24 is overlapped on the cooling fin 4, without the need for additional fixing steps, thereby simplifying the installation process of the fixing member 2 and facilitating the batch installation of the fixing member 2.

[0043] In some embodiments, the slide hole 211 extends in an extension direction close to the connecting portion 24 and penetrates the connecting portion 24 to form an insertion hole (not marked), and the insertion hole is connected to the other end of the slide hole 211, ensuring that when the cooling fan 1000 is installed on the fixing member 2, the strip table 11 can slide from the insertion hole 241 into the slide hole 211 without hindrance, avoiding the situation in which, when the cooling fan 1000 is installed without an insertion hole, the inherent elasticity of the extension member 121 can only be used to apply an external force to the extension member 121 in a direction away from the fixing member 2, so that the strip table 11 can be stuck in the slide hole 211. This installation method is prone to cause excessive external force to be applied, resulting in damage to the extension member 121.

[0044] In some embodiments, the number of the extension members 121 and the fixing members 2 are both two, the two extension members 121 are located on both sides of the air outlet 124, one fixing member 2 is arranged on the strip table 11 on one extension member 121, and the connecting parts 24 of the two fixing members 2 are respectively connected to the two ends of the heat dissipation fins 4.

[0045] It is worth noting that the material of the fixing part 2 includes but is not limited to alloy material, hard plastic, etc. In the present embodiment, the material of the fixing part 2 is preferably alloy material to enhance the overall strength of the fixing part 2 and avoid damage during installation.

[0046] Regarding the above-mentioned screw connection member 3, the screw connection member 3 may be a bolt, a screw, etc. In this embodiment, the screw connection member is preferably a screw.

[0047] In some embodiments, the cooling fan 1000 also includes a buffer gasket (not shown), which is arranged on another surface of the shell 12 away from the heat dissipation element, and is used to abut against the mounting device, where the mounting device refers to the shell of a laptop computer, etc., so as to prevent the cooling fan 1000 from rotating under the action of gravity when the mounting device on which the cooling fan 1000 in this embodiment is installed is flipped and moved, resulting in a weakened cooling effect of the cooling fan.

[0048] It can be understood that the buffer gasket needs to be set to avoid the air outlet 124a, the number of the buffer gasket is at least one, and the specific position distribution only needs to ensure that the buffer gasket can abut against the installation equipment, which will not be explained in this embodiment.

[0049] In the embodiment of the utility model, the heat dissipation fan 1000 includes a fan body 1, a fixing member 2, a screw member 3 and a heat dissipation fin 4, wherein the fan body 1 is provided with a strip-shaped table 11; the fixing member 2 is provided with a fixing hole 21, and the fixing member 2 also includes a connecting portion 24, a fixing portion 22 and a mounting portion 23, wherein the fixing hole 21 is provided on the fixing portion 22, the fixing hole 21 includes a sliding hole 211 and a rotating hole 212, and one end of the sliding hole 211 is connected to the rotating hole 212; the connecting portion 24 is fixed to the heat dissipation fin 4, the mounting portion 23 is provided with a through hole 231, and the fixing hole 21 is provided with a screw member 3 and a screw member 3. The screw connection 3 passes through the through hole 231 to screw the mounting portion 23 to an external device, wherein when the length direction of the strip table 11 is the same as the axial direction of the sliding hole 211, the strip table 11 can be inserted into the sliding hole 211 and slide along the sliding hole 211 to the rotating hole 212, the strip table 11 can rotate in the rotating hole 212, and when the length direction of the strip table 11 is staggered with the extension direction of the sliding hole 211, the inner wall of the rotating hole 212 and the strip table 11 cooperate to limit the strip table 11 from sliding from the rotating hole 212 to the sliding hole 211. The strip table 11 is moved in the sliding hole 211 to the rotating hole 212, and is rotated in the rotating hole 212 to limit the position of the strip table 11, thereby realizing a screw-free fixing method for the cooling fan 1000, reducing the opening holes required for external devices, and the connection method between the strip table 11 and the fixing member 2 facilitates the installation and disassembly of the cooling fan 1000.

[0050] The utility model also provides an electronic device embodiment, the electronic device includes the above-mentioned heat dissipation fan 1000, the structure and function of the heat dissipation fan 1000 can refer to the above-mentioned embodiment, and will not be described in detail here.
