Aluminum Folded Fin Heat Sink

Introduction

Aluminum folded fin heat sink is a heat exchange device made of aluminum material, which adopts folded fin structure design to optimize heat dissipation by increasing surface area. The main structure of this heat sink consists of an aluminum alloy base and multiple folded fins. The folded fins are usually folded into a wavy or other specific shape by a progressive stamping process to increase the surface area in contact with the air. The aluminum alloy base is responsible for conducting heat from the heat source to the fins, and the fins dissipate the heat to the surrounding air through natural convection.

Features

Efficient heat diffusion path design
The design of the aluminum folded fin heat sink optimizes the heat propagation path through a unique fin folding method. Each fin is folded to form multiple tiny contact points, which not only increases the surface area, but also allows the heat to be quickly dispersed on the contact surface. Compared with flat fin heat sinks, folded fins can more effectively diffuse heat from the base to the entire fin structure, avoiding heat concentration and ensuring that each contact point can fully play a role in heat dissipation.

Optimized wind resistance and fluid mechanics characteristics
The fluid mechanics optimization design of the aluminum folded fin heat sink makes the air flow smoother and reduces the resistance of the air flow through the precise control of the angle and spacing of the fins. This structure not only increases the air circulation speed, but also ensures that the air forms an efficient heat exchange on the fin surface. Compared with traditional radiators, the special layout of the folded fins reduces the retention of hot air flow and ensures efficient convection heat dissipation. This fluid mechanics optimization design improves the adaptability of the radiator under high and low wind speed conditions, enabling it to maintain excellent heat dissipation performance in different working environments.

High temperature resistance and stability
The high temperature resistance of aluminum alloy materials enables the folded fin heat sink to maintain excellent heat dissipation effect in high temperature environments. Compared with other metal materials, aluminum has higher oxidation resistance, and a natural oxide film will form on its surface, which has natural anti-corrosion function. This feature makes the aluminum folded fin heat sink less likely to have performance degradation problems under long-term high-temperature operation. Even under high temperature load, the structure and performance of the radiator are still stable and reliable, suitable for long-term, high-frequency working conditions.

Self-cleaning function
The fin surface of the aluminum folded fin heat sink has a certain self-cleaning property. Since the aluminum material itself is relatively smooth, dust and dirt are not easy to accumulate on its surface. This surface characteristic enables the radiator to maintain efficient heat dissipation for a long time without frequent cleaning. Compared with other types of radiators, this self-cleaning function reduces the maintenance frequency of the equipment, reduces operating costs, and improves the long-term stability of the equipment.
