Copper Folded Fin Heat Sink
Introduction
Copper folded fin heat sinks are manufactured using a progressive stamping process that folds a continuous sheet of metal into a wavy shape to maximize the heat dissipation surface area. The folded fins are connected to the heat sink base by brazing, solder or epoxy resin, ensuring that heat can be quickly transferred from the heat source to the heat sink and dissipated through the increased surface area.

Features
Folded fin structure of copper
The unique feature of copper folded fin heat sinks is the folded structure of their fins. These fins are not simply flat metal sheets, but are folded into wavy or other complex shapes through a progressive stamping process to maximize the surface area of the heat sink. This folding process increases the surface area of the fins, allowing copper folded fin heat sinks to provide higher heat dissipation efficiency in a smaller volume. By optimizing the folding angle and fin shape, the air flow path of the heat sink is effectively improved, further enhancing its natural convection capacity.
Optimized combination of copper and aluminum materials
Copper folded fin heat sinks usually combine copper and aluminum. Copper is the core component of the heat sink and is responsible for the rapid conduction of heat, while aluminum is used as the fin part. This design strategy makes full use of the high thermal conductivity of copper and the lightweight properties of aluminum. Copper has a much higher thermal conductivity than aluminum and can quickly conduct heat from the heat source to the fins, while the lightweight properties of aluminum help reduce the weight of the overall heat sink.
Precision connection process
The connection process used by copper folded fin heat sinks, such as brazing, epoxy resin or welding technology, greatly improves the overall performance of the heat sink. The folded fins are tightly combined with the substrate through efficient connection methods to ensure that heat can be transferred to the fins through the shortest path. At the same time, the precise control of the connection process reduces the thermal resistance, ensuring that the heat sink still maintains good heat dissipation effect under high-load working conditions. In addition, the precision connection process can also enhance the structural stability of the heat sink and extend its service life, which is particularly suitable for environments that require long-term and efficient heat dissipation.
High stability and environmental adaptability
The stability and corrosion resistance of copper in high temperature environments make copper folded fin heat sinks highly adaptable, especially suitable for heat dissipation applications in harsh environments. Copper's oxidation resistance and high temperature resistance ensure that the heat sink will not experience material fatigue or performance degradation when running at high temperatures for a long time. This stability makes copper folded fin heat sinks not only suitable for conventional electronic equipment, but also widely used in extreme temperature changes and harsh environments to meet more demanding heat dissipation needs.
