Description

Technical Field

[0001] This utility model relates to the field of graphics card technology, and in particular to a turbine-type graphics card with a noise reduction device. Background Technology

[0002] With the surge in demand for graphics processing, the power consumption and heat generation of graphics cards have increased significantly, making efficient heat dissipation crucial. Air cooling is widely used due to its cost-effectiveness, and its core principle is that a fan drives airflow over heat sink fins to dissipate heat.

[0003] To meet the demand for thinner graphics cards, the turbine-style graphics card was developed. Its unique feature is that the fan blows air from the side of the graphics card, allowing the airflow to pass laterally through closely arranged heatsink fins. This design significantly reduces the thickness of the graphics card, resulting in a more compact structure.

[0004] However, the side-blowing mode has significant drawbacks in practical use. The airflow travels at high speed through the narrow fin channels, easily generating turbulence and vortices, leading to aerodynamic noise. Simultaneously, the airflow impact can also cause vibrations in the fins and even the fan structure, further exacerbating the noise. This noise not only affects the user's work or rest environment, reducing comfort, but may also limit the product's application in noise-sensitive scenarios.

[0005] Based on this, in order to meet the noise reduction requirements of turbine-style graphics cards, we propose a turbine-style graphics card with a noise reduction device. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies, such as the high-speed flow of air in the side-blowing mode within the narrow fin channel, which easily generates turbulence and vortices, leading to aerodynamic noise. Therefore, this invention proposes a turbine-style graphics card with a noise reduction device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] Design a turbine-style graphics card with a noise reduction device, including:

[0009] A PCB, a fin module mounted on the PCB, and a fan, wherein the fin module is mounted on the side of the fan;

[0010] A sound-insulating component is fitted on the outside of the fin module. The sound-insulating component has open ends and surrounds the sides and top of the fin module. The sound-insulating component has a sound-absorbing chamber inside and several sound-absorbing holes are formed on the inner side of the sound-insulating component.

[0011] Furthermore, the fan is a turbo fan;

[0012] An clearance opening is provided on the end face of the PCB, the bottom of the fan is placed in the clearance opening, and the frame of the fan is connected and fixed to the PCB by fasteners.

[0013] Furthermore, the fin module includes a heat-conducting plate and a frame, with the heat-conducting plate attached to the heating element of the PCB;

[0014] The frame has several fins formed inside, and air ducts are formed between two adjacent fins. The air ducts and the fan are arranged opposite to each other.

[0015] Furthermore, the sound insulation component includes two horizontal arm segments and a horizontal segment connecting the two arm segments, and the two arm segments and the fin module are connected and fixed.

[0016] A sound-absorbing space is formed between the inner side of the horizontal section and the upper side of the fin module.

[0017] Furthermore, the sound-absorbing holes are regularly formed on the inner surface of the arm segment and the connecting inner surface of the arm segment and the horizontal segment.

[0018] Furthermore, it also includes the outer casing;

[0019] The end face of the housing has an opening to avoid the fan, and the outer side of the housing is also formed with housing fins.

[0020] Furthermore, the length of the sound insulation component is adapted to the length of the fin module, and the upper surface of the outer shell has an outward protrusion to accommodate the sound insulation component.

[0021] The present invention proposes a turbine-style graphics card with a noise reduction device. The beneficial effects are as follows: By adding a sound-insulating component to the outside of the fin module, and the sound-absorbing hole inside the sound-insulating component, the noise generated by the airflow during the heat dissipation of the fin module can be effectively absorbed. After the noise enters the sound-absorbing hole, it will be further conducted to the internal silencing chamber. Through the friction generated by the reciprocating movement of the air in the sound-absorbing hole and the resonance of the chamber, the sound energy is effectively consumed, thereby achieving a significant noise reduction effect. This design significantly reduces the operating noise of the graphics card without affecting its heat dissipation function, optimizes the usage environment, and reduces the impact on the surrounding environment.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Reference Figure 1-6 As an embodiment of this utility model, a turbine-style graphics card with a noise reduction device is disclosed. Specifically, the graphics card includes a PCB1 and a fin module 2 and a fan 3 mounted on the PCB1. Of course, in this embodiment, the fin module 2 and the fan 3 are mounted on the surface of the PCB1 with heat-generating components, and the fin module 2 is mounted on the side of the fan 3.

[0031] A sound-insulating component 4 is fitted on the outside of the fin module 2. The sound-insulating component 4 is open at both ends and surrounds the sides and top of the fin module 2. The sound-insulating component 4 has a sound-absorbing chamber 41 inside. Several sound-absorbing holes 42 are formed on the inner side of the sound-insulating component 4. Preferably, the diameter of the sound-absorbing holes 42 in this embodiment can be set to 0.5mm-3mm. The specific value can be adjusted by those skilled in the art according to factors such as the power of the fan. No further restrictions are imposed here.

[0032] In addition, the sound insulation component 4 described in this embodiment includes, but is not limited to, polyester fiberboard, wood board, or metal plate with sound-absorbing cotton pasted inside, all of which have good sound absorption capabilities to ensure the stability of noise reduction.

[0033] like Figure 6As shown, in this embodiment, a sound insulation component 4 is added to the outside of the fin module 2. The sound insulation component 4 has a sound-absorbing hole 42 inside, which can effectively absorb the noise generated by the airflow when the fin module 2 dissipates heat. After the noise enters the sound-absorbing hole 42, it will be further conducted to the internal silencing chamber 41. Through the friction generated by the reciprocating motion of the air in the sound-absorbing hole 42 and the resonance of the cavity, the sound energy is effectively consumed, thereby achieving a significant noise reduction effect. This design significantly reduces the operating noise of the graphics card without affecting its heat dissipation function, optimizes the usage environment, and reduces the impact on the surrounding environment.

[0034] In some embodiments, the fan 3 described in this invention is a turbo fan;

[0035] An opening 10 is provided on the end face of the PCB1. The bottom of the fan 3 is placed in the opening 10. The frame of the fan 3 is connected and fixed to the PCB1 by fasteners. Preferably, the fasteners in this embodiment can be bolts. That is, in this embodiment, a turbine fan design is used to achieve side air cooling. The turbine fan blows cold air into the fin module 2 to achieve heat dissipation of the fin module 2.

[0036] In addition, the fin module 2 in this embodiment includes a heat-conducting plate 21 and a frame 22. The heat-conducting plate 21 is attached to the heat-generating element of the PCB1. The heat on the PCB1 is conducted upward through the heat-conducting plate 21 and transferred to the frame 22, and then the fan 3 blows air to dissipate heat.

[0037] The frame 22 has several fins 23 formed inside, and an air duct is formed between two adjacent fins 23. The air duct and the fan 3 are arranged opposite to each other. That is, when heat is transferred to the fins 23 through the frame 22, the heat is discharged by the airflow blown in by the fan 3. At the same time, the noise generated during the airflow will enter the sound insulation component 4. The noise will enter the silencing chamber 41 along the sound absorption hole 42. The sound energy is effectively consumed by the friction generated by the reciprocating movement of the air in the sound absorption hole 42 and the resonance of the cavity, thereby achieving the noise reduction effect.

[0038] It should be noted that, in this embodiment, the sound insulation component 4 includes two horizontal arm segments 43 and a horizontal segment 44 connected between the two arm segments 43. The two arm segments 43 and the horizontal segment 44 together form a U-shaped structure. The two arm segments 43 are connected and fixed to the fin module 2. A sound-absorbing space 45 is formed between the inner side of the horizontal segment 44 and the upper side of the fin module 2. The sound-absorbing space 45 is used to increase the space for noise propagation so that noise can stably enter the interior of the anechoic chamber 41.

[0039] Preferably, in this embodiment, the sound-absorbing holes 42 are regularly formed on the inner surface of the arm segment 43 and the inner surface of the arm segment 43 and the horizontal segment 44.

[0040] In some embodiments, the graphics card described in this utility model further includes a casing 5;

[0041] The end face of the outer casing 5 has an opening 51 to avoid the fan 3. The outer side of the outer casing 5 is also formed with casing fins 52, which are integrally formed with the outer casing to further improve heat dissipation efficiency. In addition, the outer casing 5 in this embodiment can also be connected and fixed to the PCB1 by fasteners such as bolts.

[0042] Preferably, in this embodiment, the length of the sound insulation component 4 is adapted to the length of the fin module 2. In this embodiment, the length of the sound insulation component 4 and the length of the fin module 2 are the same, and the upper surface of the outer shell 5 has an outward protrusion 53 for accommodating the sound insulation component 4.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
