Ram Snap Fin Heat Sink

Product introduction

As the performance of electronic equipment continues to rise, the heat dissipation problem has become one of the key factors restricting its stable operation and life. With its excellent thermal conductivity, unique structural design and a wide range of applications, the copper shovel radiator has gradually emerged in the heat dissipation market, and has become the focus of attention of many electronic equipment manufacturers and enthusiasts.

Copper, as a commonly used heat dissipation material, has a very high thermal conductivity. Compared to other common metals such as aluminum, copper has a higher thermal conductivity, which means that it can conduct heat away from the heat source more quickly, effectively reducing the temperature of the heating element. In electronic devices, rapid conduction of heat is critical because high temperatures can lead to reduced performance, shortened life, or even damage to electronic components.

In addition, copper has good corrosion resistance and can resist the influence of environmental factors such as humidity and oxidation to a certain extent, ensuring that the heat sink maintains stable heat dissipation performance during long-term use. The stability of this material provides a solid guarantee for the reliable operation of electronic equipment, especially for those application scenarios with harsh heat dissipation requirements and harsh working environment.

Structural characteristics

Spatula design: The unique spatula structure of the copper spatula radiator fin is one of its distinguishing features from other radiators. This design increases the contact area between the heat sink and the air, allowing heat to be transferred to the air more efficiently. The spatula surface is usually treated with fine processing to improve its heat dissipation and aerodynamic performance, ensuring that air can flow smoothly over the surface of the heat sink and take away more heat.

Fin layout: On the heat sink, there are usually dense fins arranged. These fins are parallel to each other and evenly spaced, further increasing the heat dissipation area. Parameters such as fin thickness, height and spacing are carefully optimized to balance heat dissipation efficiency with the complexity of the manufacturing process. Thinner fins can provide greater heat dissipation area, but also need to consider its mechanical strength and processing difficulty; Reasonable fin spacing can ensure the smooth flow of air between fins, to avoid the obstruction of air flow and reduce the heat dissipation effect.

Base and heat pipe (if any) : Some high-end copper shovel radiators use heat pipe technology to closely combine the heat pipe and heat sink base. The working medium inside the heat pipe will quickly evaporate after being heated, and the heat will be quickly transferred to other parts of the heat sink, and then the heat will be released to the fin for dissipation through condensation. This synergistic effect of heat pipe and heat sink greatly enhances the overall heat dissipation capacity of the heat sink and can more effectively respond to the heat dissipation requirements of high-power electronic components.

Manufacturing process

Precision casting or forging: Copper shovel radiator fins are usually manufactured using precision casting or forging processes to ensure the accuracy of their shape and the uniformity of their internal organizational structure. In the casting process, it is necessary to strictly control the temperature of the mold, the pouring speed and pressure of the copper liquid, so as to avoid defects such as pores and cracks and ensure the quality and performance of the heat sink. The forging process can make the internal grains of copper more refined, improve its mechanical properties and thermal conductivity, but the cost is relatively high, and it is often used in the manufacture of high-end products with high performance requirements.

Machining: After casting or forging, the heat sink blank needs to undergo a series of machining processes, including cutting, milling, drilling, grinding, etc. These processes are designed to achieve the precise size and shape requirements of the heat sink, while the surface is carefully treated to improve the surface finish and flatness to enhance the heat dissipation effect and contact with electronic components. For example, the base of the heat sink is ground to minimize the contact thermal resistance between it and the electronic components, ensuring that the heat can be smoothly transferred to the heat sink.

Surface treatment: In order to further improve the heat dissipation performance and corrosion resistance of the heat sink, it is usually subjected to surface treatment. Common surface treatment methods include nickel plating, tin plating, anodizing, etc. Nickel plating can form a dense nickel layer on the surface of the heat sink, enhance its oxidation resistance and corrosion resistance, and improve the surface hardness and wear resistance; Tin plating is often used in some application scenarios with high electrical conductivity requirements, which can reduce contact resistance while ensuring heat dissipation performance. Anodizing can form an oxide film with a porous structure on the surface of the heat sink, increase the heat dissipation area, improve the heat dissipation efficiency, and also improve the appearance quality of the heat sink.
