Description

Technical Field

[0001] This utility model belongs to the field of vibration dampers, and relates to a heat sink, particularly a silicone oil vibration damper heat sink. Background Technology

[0002] Silicone oil vibration dampers are crucial components in rotating parts such as engine crankshafts, absorbing and reducing torsional vibrations through the viscous shear damping of internal silicone oil. However, during operation, the silicone oil generates significant heat due to continuous shearing, leading to a substantial temperature increase. This temperature rise reduces the viscosity of the silicone oil, further weakening its damping performance and creating a vicious cycle of performance degradation. In extreme cases, overheating can even cause premature aging of the silicone oil or component damage. Therefore, efficient heat dissipation is essential for maintaining the stability and lifespan of silicone oil vibration dampers.

[0003] Existing vibration damper heat dissipation solutions mostly employ simple heat dissipation fins on the outside of the housing to increase the heat dissipation area. However, this traditional structure has obvious drawbacks: First, its heat dissipation path is singular, mainly relying on the surface of the heat dissipation fins and natural convection with the air, and the heat dissipation efficiency is approaching its limit; second, heat accumulates severely at the root of the fins, while the heat dissipation effect at the end of the fins is limited, resulting in an uneven overall temperature field. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a silicone oil vibration damper heat sink to solve these problems.

[0005] The purpose of this utility model can be achieved through the following technical solution: a silicone oil vibration damper heat sink, characterized in that it includes a main body, the main body is provided with a plurality of heat sink fins and heat sink grooves, the heat sink fins are fixed inside the heat sink grooves, the main body is also provided with a plurality of heat sink holes communicating with the heat sink grooves, and the outer end of the heat sink fins is provided with at least one through hole to facilitate improving heat dissipation efficiency. The heat dissipation fins are fixed inside the heat dissipation groove and extend to the inner diameter of the main body. At least one weight-reducing hole is provided at the end to reduce the overall weight of the heat dissipation fins. The main body and the heat dissipation fins are integrally formed, and there is a heat dissipation gap between the heat dissipation fins and the side wall of the heat dissipation groove.

[0006] In the aforementioned silicone oil vibration damper heat sink, the width of the heat dissipation gap between the heat dissipation fins and the side wall of the heat dissipation groove is 0.1mm-2mm.

[0007] In the aforementioned silicone oil vibration damper heat sink, the heat dissipation hole is located on the bottom wall of the heat dissipation groove and is connected to the heat dissipation groove. Its through hole passes through the heat dissipation fin and is connected to the heat dissipation hole.

[0008] In the aforementioned silicone oil vibration damper heat sink, the cross-sectional shape of the heat sink fins is rectangular, trapezoidal, or arc-shaped.

[0009] In the aforementioned silicone oil vibration damper heat sink, the cross-sectional shape of the heat dissipation gap is arc-shaped or wavy to enhance the heat dissipation area and reduce airflow disturbance.

[0010] Compared with existing technologies, the heat sink of this silicone oil vibration damper achieves efficient heat dissipation, structural stability and lightweight through its ingenious multi-layer structure, making it particularly suitable for components such as silicone oil vibration dampers that operate under high temperature and high speed conditions.

[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] like Figure 1 , Figure 2 As shown, the heat sink of this silicone oil vibration damper includes a main body 1, on which multiple heat dissipation fins 2 and heat dissipation grooves 3 are provided. The heat dissipation fins 2 are fixed inside the heat dissipation grooves 3. The main body 1 also has multiple heat dissipation holes 4 that communicate with the heat dissipation grooves 3. The outer end of the heat dissipation fins 2 is provided with at least one through hole 5 to facilitate improved heat dissipation efficiency. The heat dissipation fins 2 are fixed inside the heat dissipation grooves 3 and extend to the inner diameter position of the main body 1. The end is provided with at least one weight reduction hole 6 to reduce the overall weight of the heat sink. The main body 1 and the heat dissipation fins 2 are integrally formed, and there is a heat dissipation gap between the heat dissipation fins 2 and the side wall of the heat dissipation grooves 3.

[0016] The width of the heat dissipation gap between the heat dissipation fins 2 and the sidewall of the heat dissipation groove 3 is 0.1mm-2mm. The heat dissipation hole 4 is located on the bottom wall of the heat dissipation groove 3 and is connected to the heat dissipation groove 3. Its through hole 5 passes through the heat dissipation fins 2 and is connected to the heat dissipation hole 4. The cross-sectional shape of the heat dissipation fins 2 is rectangular, trapezoidal, or arc-shaped. The cross-sectional shape of the heat dissipation gap is arc-shaped or wavy to enhance the heat dissipation area and airflow disturbance.

[0017] During operation, heat is generated internally due to shearing action, and this heat is conducted to the main body 1 of the heat sink through contact. The heat on the main body 1 is first transferred to multiple heat dissipation fins 2. The heat dissipation fins 2, through their large surface area, exchange heat with the flowing air via convection, rapidly dissipating the heat to the surrounding environment. The heat dissipation fins 2 are not isolated, but are arranged inside the heat dissipation slot 3, with precise heat dissipation gaps maintained between them and the slot wall, forming narrow channels. When air flows through, the flow velocity increases, which can more effectively remove the heat accumulated at the bottom of the slot and the root of the fins. At the same time, the heat dissipation holes 4 opened on the bottom wall of the heat dissipation slot 3 and the through holes 5 penetrating the outer ends of the heat dissipation fins 2 together form a three-dimensional airflow network. These holes not only introduce additional cooling airflow paths, enhance air turbulence, and break up the stagnant air boundary layer, but also further improve heat dissipation efficiency. In addition, the weight reduction holes 6 located at the ends of the heat dissipation fins 2 reduce the overall weight and further optimize airflow. Ultimately, through the synergistic effect of the expanded surface area of ​​the heat dissipation fins 2, the chimney effect of the heat dissipation gap, and the forced convection formed by the heat dissipation holes 4 and the through holes 5, efficient and uniform cooling of the silicone oil vibration damper is achieved.
