Advantages and Disadvantages of Copper-Aluminum Composite Radiators
The product is highly cost-effective.
Copper and aluminum materials exhibit excellent thermal conductivity, with far superior heat dissipation capabilities compared to other materials. The thermal efficiency of copper-aluminum composite heat sinks is also significantly higher than that of other material-based heat sinks. Moreover, as both copper and aluminum are non-ferrous metals, their value increases over time, making the copper-aluminum composite heat sinks highly valuable and retaining their worth well.
2. Excellent comprehensive mechanical properties.
Aluminum alloy profiles are widely used in the construction industry in our country due to their high strength, excellent water and air tightness, good thermal conductivity, exquisite appearance, and ease of processing. Particularly, their superior thermal conductivity has gained attention from many radiator manufacturers in recent years.
3. Excellent resistance to alkaline water corrosion, with a long service life.
High-quality copper-aluminum composite finned radiators are manufactured using advanced internal flange hydraulic expansion technology. The header tubes and fin tubes of the radiators are all made of purple copper, boasting strong corrosion resistance and eliminating the need for internal anti-corrosion treatment. Consequently, they exhibit excellent resistance to alkaline water corrosion. Currently, the copper-aluminum composite column fin radiators promoted and produced in our country can have a corrosion resistance life of up to 50 years under high alkalinity water conditions, with an annual corrosion rate of 0.005mm/year. This leaves ample room for a service life of over 30 years.
4. Wide applicability.
The copper-aluminum composite panel-type heating radiator is made by bonding copper tubes with aluminum profiles, which are tightly sealed through high-pressure expansion by equipment. It boasts a compact structure, attractive appearance, ease of cleaning, light weight, high pressure-bearing capacity, and excellent heat dissipation performance (radiation and convection), ensuring durability and suitability for all heating systems.
