Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation fans, in particular to a connected heat dissipation fan with inconsistent frame and blade sizes. Background Art

[0002] With the rapid development of electronic devices, heat dissipation has become one of the key factors restricting their performance. As an indispensable heat dissipation component in electronic devices, the performance optimization of cooling fans is directly related to the stability and service life of the equipment. Currently, cooling fans are mainly divided into two categories: single-body cooling fans and integrated cooling fans. Single-body cooling fans have a relatively simple structure, consisting of a frame and a single fan blade, and are suitable for small devices or devices with low heat dissipation requirements. Integrated cooling fans, on the other hand, are made by connecting multiple single-body fans in series. This is not only convenient to install, but also significantly improves heat dissipation performance. They are widely used in high-performance servers, mainframe computers, and other applications with high heat dissipation requirements.

[0003] Existing one-piece cooling fans have a common design problem: each frame cavity and fan blade are of the same size. This design is particularly prominent in cooling fans with light-emitting components. Because the light-emitting components occupy a certain amount of space, the size of the frame cavity and fan blades is limited, preventing the fan from fully realizing its heat dissipation potential. To accommodate the light-emitting components, the frame cavity and fan blades are often designed to be smaller, which to some extent affects the cooling efficiency of the cooling fan. To address this problem, the inventors have proposed a one-piece cooling fan with inconsistent frame and blade sizes. Utility Model Content

[0004] In view of the shortcomings existing in the above technology, the utility model provides a one-piece cooling fan with inconsistent frame and blade sizes.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a one-piece cooling fan with inconsistent frame and blade sizes, comprising a support module, a limiting module and a heat dissipation module, the limiting module being installed on the support module for limiting the support module, the heat dissipation module being installed on the limiting module for dissipating heat from a computer chassis, the heat dissipation module comprising a first fan blade and a second fan blade, the first fan blade being installed on the limiting module, the second fan blade being installed on the limiting module and away from one end of the first fan blade, and the blade sizes of the first fan blade and the second fan blade being different.

[0006] As a further explanation, the limiting module includes limiting rods, and multiple limiting rods are vertically installed on the supporting module for limiting the fan blades. The first fan blade and the second fan blade are respectively located inside the multiple limiting rods.

[0007] As a further explanation, it also includes a limiting column, which is vertically installed on the support module. The limiting column extends outward to be provided with a protrusion, which is vertically installed on the support module for limiting the support module.

A second frame hole is extended outward from the first frame hole, and the second frame hole is vertically installed on the supporting module and is away from one end of the first frame hole.

The protrusion is located inside the frame upper cover, and the limiting column is located inside the frame lower cover for cooperating with the protrusion. The first frame hole is located on the upper surface of the frame lower cover, and the second frame hole is located on the upper surface of the frame lower cover.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] like Figure 1-3 As shown, the utility model is a one-piece cooling fan with inconsistent frame and blade sizes, including a support module, a limiting module and a heat dissipation module. The limiting module is installed on the support module to limit the support module, and the heat dissipation module is installed on the limiting module to dissipate heat from the computer case. The heat dissipation module includes a first fan blade 21 and a second fan blade 22. The first fan blade 21 is installed on the limiting module, and the second fan blade 22 is installed on the limiting module and away from one end of the first fan blade 21. The blade sizes of the first fan blade 21 and the second fan blade 22 are different.

[0019] Specifically, the first fan blade 21 and the second fan blade 22 begin to rotate at a certain speed. The two fan blades are uniquely designed and have different sizes to meet different heat dissipation requirements;

[0020] The first fan blade 21, due to its larger blade area, can generate stronger airflow and is suitable for use in areas requiring higher heat dissipation efficiency. When the first fan blade 21 rotates, it draws in surrounding air and exhausts it through the first frame cavity 301, forming a powerful airflow that effectively removes heat from the computer case.

[0021] Although the second blade 22 has a smaller blade, its design is more compact, capable of providing effective airflow within a limited space. When the second blade 22 rotates, it draws air from the second frame cavity 302 and discharges the air through the rotation of the blade, forming another airflow, further enhancing the heat dissipation effect. At the same time, because the second blade 22 is located at an end away from the first blade 21, the airflow between the two can complement each other, improving the overall heat dissipation efficiency.

[0022] The limiting module includes limiting rods 31 . A plurality of limiting rods 31 are vertically mounted on the supporting module for limiting the fan blades. The first fan blade 21 and the second fan blade 22 are respectively located inside the plurality of limiting rods 31 .

[0023] Specifically, the limiting rod 31 not only supports the fan blades, but also ensures that the fan blades will not deviate from the predetermined track during rotation and maintain a stable running trajectory.

[0024] It also includes a limiting column 32, which is vertically installed on the support module. The limiting column 32 extends outward to be provided with a protrusion 33, which is vertically installed on the support module for limiting the support module.

[0025] Specifically, the limiting column 32 and the protrusion 33 thereon cooperate with the support module (the frame lower cover 12 and the frame upper cover 11) to further enhance the stability of the fan structure and prevent components from loosening or being damaged due to vibration or external force.

[0026] The first frame hole 301 is vertically mounted on the supporting module. A second frame hole 302 is extended outward from the first frame hole 301 . The second frame hole 302 is vertically mounted on the supporting module and is away from one end of the first frame hole 301 .

[0027] Specifically, the first frame hole 301 and the second frame hole 302 are mainly used to cooperate with the fan blades to suck the air inside the chassis into the first frame hole 301 and the second frame hole 302 respectively when the fan blades rotate, and discharge the air through the rotation of the fan blades to form another airflow, thereby further enhancing the heat dissipation effect.

[0028] The support module includes a frame lower cover 12, and a frame upper cover 11 is extended outward from the frame lower cover 12. The frame upper cover 11 is installed on the top of the frame lower cover 12 for protecting the fan blades. The protrusion 33 is located inside the frame upper cover 11, and the limiting column 32 is located inside the frame lower cover 12 for cooperating and connecting with the protrusion 33. The first frame hole 301 is located on the upper surface of the frame lower cover 12, and the second frame hole 302 is located on the upper surface of the frame lower cover 12.

[0029] Specifically, the lower frame cover 12 and upper frame cover 11 provide a mounting platform for the fan blades. Upper frame cover 11 is mounted on top of lower frame cover 12, protecting the fan blades from damage by foreign objects. Furthermore, the upper and lower frames 11, 12 are connected by connectors 102, allowing multiple cooling fan units to be combined to accommodate computer cases of varying sizes.

[0030] It also includes a support frame 101, which is installed inside the lower cover 12 of the frame. The upper cover 11 of the frame is provided with a connecting piece 102 extending outward. The connecting piece 102 is installed on the top of the upper cover 11 of the frame and is used to match multiple upper covers 11. Multiple limit rods 31 are located inside the support frame 101.

[0031] Specifically, the support frame 101

[0032] A transparent plate 1 is provided extending outward from the frame upper cover 11 , and the transparent plate 1 is installed on one side of the frame upper cover 11 .

[0033] Specifically, the design of the transparent plate 1 not only increases the aesthetics, but also allows the user to observe the operating status of the fan to ensure that the fan is operating normally.

[0034] A light-emitting component 2 is provided extending outward from the second frame cavity 302 , and the light-emitting component 2 is installed on the outer wall of the second frame cavity 302 .

[0035] Specifically, a light-emitting element 2 extends outward from the second frame cavity 302. When the fan is running, the light-emitting element 2 emits a soft light, adding a touch of bright color to the computer case. The light-emitting element 2 is mounted on the outer wall of the second frame cavity 302, which does not interfere with the flow of air while providing visual enjoyment for the user.
