Understanding Copper Aluminum Composite heat sinks

Copper-aluminum composite heat sinks is a radiator designed for high-power electronic equipment.Copper plates and aluminum plates are combined using special bonding technology to form a high-strength metal material with high heat dissipation efficiency and corrosion resistance.Copper-aluminum composite radiators will be very popular in the future due to their amazing heat conduction speed and physical properties of recycling, as well as outstanding anti-corrosion performance, wide applicability, good heat-to-price ratio, high value retention rate and beautiful appearance. Will become the dominant type of new heat sinks for a long time.
                                                                                                                                      
1. Thermal conductivity
The upper layer of the copper-aluminum composite heat sinks is a copper plate, which has high thermal conductivity and can quickly transfer the heat from the heat sinks device to the surface of the radiator.The thermal conductivity of copper is 401W/mk, which is about three times that of aluminum. The lower aluminum plate has a higher thermal conductivity, allowing the heat sinks to quickly transfer heat to the air.
2.Corrosion resistance
Copper-aluminum heat sinks use special bonding technology to bond copper plates and aluminum plates together. At the same time, an oxide film is formed on the surface of the aluminum plates, which plays a certain role in the surface of the radiator and prevents corrosion.The copper-aluminum composite radiator will be coated with a layer of anti-corrosion oil during use of the heat sink  to effectively improve the corrosion resistance.
3. Mechanical properties
Copper-aluminum composite heat sinks combine two metal materials, copper and aluminum, to create a heat sinks that can withstand greater loads without deformation or damage.
4. Small size and light weight
The copper-aluminum composite heat sinks adopts an optimized design, which reduces the use of internal materials and can better adapt to smaller and lighter electronic devices. Copper-aluminum composite heat sinks are mainly used in high-power electronic equipment, such as servers, industrial computers, graphics cards, etc. These equipment have high power and require reliable heat dissipation to ensure safe and reliable use.In addition, copper-aluminum composite heat sinks are also widely used in the automotive industry, military industry, photovoltaic power generation and other fields.
