Advantages and Disadvantages of Copper-Aluminum Composite Radiators
1. Economically strong.
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 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 for their investment potential.
2. Excellent comprehensive mechanical properties.
Aluminum alloy profiles are widely used in the construction industry in our country due to their high strength, good water and air tightness, excellent thermal conductivity, attractive appearance, and ease of processing. Especially, their superior thermal conductivity has been recognized by many radiator manufacturers in recent years.
3. Excellent resistance to alkaline water corrosion, long lifespan.
High-quality copper-aluminum composite heat sinks, manufactured using internal flange hydraulic expansion technology. The headers and fins of the radiators are all made of purple copper, offering strong corrosion resistance and eliminating the need for internal anti-corrosion treatment. Consequently, it boasts excellent resistance to alkaline water corrosion. The copper-aluminum composite column fin radiators currently promoted for production in our country can withstand corrosion for up to 50 years under high alkalinity water conditions, assuming an annual corrosion rate of 0.005mm/year, leaving ample room for a lifespan of over 30 years.
4. Broad applicability.
The copper-aluminum composite plate radiator is made by bonding copper tubes with aluminum profiles, tightly sealed through high-pressure expansion using equipment. It features a compact structure, attractive appearance, ease of cleaning, light weight, high pressure-bearing capacity, and excellent heat dissipation (radiative and convective), ensuring durability. Suitable for all heating systems.
