Description

Technical Field

[0001] This utility model relates to the field of heat dissipation device technology, specifically a high-strength, lightweight, porous metal heat dissipation device. Background Technology

[0002] The high-strength lightweight metal porous heat dissipation device is an innovative product that integrates materials science and thermal management technology. It uses lightweight and high-strength metals such as titanium alloy and aluminum alloy as the base material and constructs a three-dimensional interconnected porous structure through precision processes such as powder metallurgy and laser cladding. It achieves efficient heat dissipation while taking into account both mechanical properties and lightweight advantages.

[0003] Solid metal heat dissipation structures have high strength but are heavy. Lightweight materials such as plastics and ordinary porous metals are difficult to meet the requirements for impact and vibration resistance. In the field of automotive electronics, excessive weight often affects the driving range. Moreover, heat dissipation efficiency is negatively correlated with structural strength. Traditional porous metals have uniform pore size, which is prone to heat dissipation failure due to pore blockage. Furthermore, they are prone to structural deformation at high temperatures. Therefore, those skilled in the art have provided high-strength lightweight porous metal heat dissipation devices to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength, lightweight, porous metal heat dissipation device to solve the problems mentioned in the background art.

Connecting holes are provided on both the upper and bottom surfaces of the metal heat dissipation frame. A ring-shaped arrangement of auxiliary holes is provided on both the upper and bottom surfaces of the metal heat dissipation frame. A ring-shaped arrangement of triangular and hexagonal holes is provided on both the upper and bottom surfaces of the metal heat dissipation frame. Ring-shaped strip holes, elliptical holes, and through holes are provided on the outer surface of the metal heat dissipation frame.

[0006] As a further improvement of this utility model: the upper surface and the bottom surface of the metal heat sink frame are provided with a ring of mounting holes, and each set of mounting holes is provided with mounting screws.

[0008] As a further improvement of this utility model: the diameter of each mounting hole is adapted to the nominal diameter of the mounting screw, and each mounting hole is located at the edge of the metal heat sink frame.

[0009] As a further improvement of this utility model: each of the mounting screws is made of stainless steel, and the inner wall of the metal heat sink frame is provided with a thermally conductive silicone layer.

[0010] As a further embodiment of this utility model: the metal heat sink frame is composed of an inner metal matrix composite material layer and an outer reinforcing and protective layer, wherein the inner metal matrix composite material layer is made of aluminum-based silicon carbide composite material, and the outer reinforcing and protective layer is made of aluminum nitride ceramic coating.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This high-strength, lightweight, porous metal heat dissipation device employs a composite structure with an inner layer of aluminum-based silicon carbide composite material and an outer layer of aluminum nitride ceramic coating. This design balances ultra-high strength with lightweight characteristics, significantly reducing its weight while ensuring structural stability. It is suitable for various equipment scenarios with stringent load requirements. Through multiple types of porous structures, including triangular, hexagonal, and strip-shaped holes, the heat dissipation area is maximized.

[0014] Please see Figures 1-4In this embodiment of the utility model, the high-strength lightweight metal porous heat dissipation device includes a metal heat dissipation frame 1. Connecting holes 2 are provided on both the upper and bottom surfaces of the metal heat dissipation frame 1. Auxiliary holes 3 arranged in a ring are provided on both the upper and bottom surfaces of the metal heat dissipation frame 1. Triangular holes 4 and hexagonal holes 5 are arranged in a ring on both the upper and bottom surfaces of the metal heat dissipation frame 1. Strip holes 6, elliptical holes 7, and through holes 8 are arranged in a ring on the outer surface of the metal heat dissipation frame 1. The overall design achieves synergistic optimization of strength, lightweight, heat dissipation efficiency, and installation adaptability. It has a wide range of applications and can meet the stringent requirements for heat dissipation and structural performance of high-end electronic equipment.

[0015] The upper and lower surfaces of the metal heat sink frame 1 are provided with a ring of mounting holes 9. Each set of mounting holes 9 is provided with a mounting screw 10 inside. Each mounting screw 10 is fitted with a washer 11 on the outside. Each mounting screw 10 is threaded with a nut 12 on its outer surface. The diameter of each mounting hole 9 is matched with the nominal diameter of the mounting screw 10. Each mounting hole 9 is located at the edge of the metal heat sink frame 1, which not only facilitates the installation of the equipment, but also makes the metal heat sink frame 1 more stable during the connection process.

[0016] Each mounting screw 10 is made of stainless steel. The inner wall of the metal heat sink frame 1 is provided with a thermally conductive silicone layer. The metal heat sink frame 1 is composed of an inner metal-based composite material layer and an outer reinforced protective layer. The inner metal-based composite material layer is made of aluminum-based silicon carbide composite material, and the outer reinforced protective layer is made of aluminum nitride ceramic coating. It takes into account both ultra-high strength and lightweight characteristics, and significantly reduces its own weight while ensuring structural stability, making it suitable for various equipment scenarios with strict load requirements.

[0017] The working principle of this utility model is as follows: First, the heat generated by the operation of the equipment will be quickly transferred to the thermally conductive silicone layer on the inner wall of the metal heat sink frame 1. This layer can improve the heat conduction efficiency and make the heat evenly diffused to the entire heat sink frame body. The metal heat sink frame 1 adopts a composite structure of inner aluminum-based silicon carbide composite material and outer aluminum nitride ceramic coating. The high thermal conductivity of aluminum-based silicon carbide ensures that the heat is quickly conducted to the outer layer, while the aluminum nitride ceramic coating provides protection while ensuring heat dissipation, preventing the heat sink frame from being corroded by the external environment. After heat is conducted to the surface of the heat sink frame, heat exchange is completed through a multi-type porous structure: the annular arrangement of triangular holes 4, hexagonal holes 5 and auxiliary holes 3 on the upper and bottom surfaces, combined with the strip holes 6, elliptical holes 7 and through holes 8 on the outer surface, increases the heat dissipation area by more than 40% compared with the traditional structure, greatly increasing the contact area with air. At the same time, the annular arrangement of holes forms a directional airflow channel, accelerates air circulation, and promotes the rapid dissipation of heat to the external environment. During installation, a secure assembly is achieved by using the mounting holes 9 on the edge of the metal heat sink frame 1, along with stainless steel mounting screws 10, washers 11, and nuts 12. The precise matching of the mounting holes 9 and the nominal diameter of the screws ensures a tight connection and prevents airflow leakage from affecting heat dissipation. The connection hole 2 can be used for precise docking with the equipment's heat dissipation interface to ensure a smooth heat transfer path, ultimately achieving a complete heat dissipation process of "heat conduction - uniform diffusion - efficient dissipation".
