Details
The copper-aluminum composite radiator is a heating device that combines the advantages of both copper and aluminum materials. Its core structure is composed of copper tubes and aluminum profiles, which are joined together through a hydraulic expansion process. The copper tubes serve as the heat-transfer medium and exhibit excellent corrosion resistance, making them particularly suitable for use in alkaline water environments. Without the need for additional anti-corrosion treatments, these radiators can maintain a service life of over 30 years. Meanwhile, the aluminum profiles, with their high thermal conductivity (approximately 237 W/m·K), rapidly transfer heat to the surrounding air, creating a combined radiation and convection-based heat dissipation mode.
This technology employs an internal-flange hydraulic expansion process to eliminate the gap at the copper-aluminum interface, increasing the shear strength to over 45 MPa and ensuring that the joint remains securely fastened even under long-term use. The modular design facilitates quick disassembly and maintenance; for example, the TLZY8-6/8-1.0 model features a snap-fit structure, reducing maintenance costs by 30%. A typical model, such as the TLF88-80/600-1.0 single-column unit, delivers a heat dissipation capacity of 138.6 W and is suitable for hot water media with temperatures below 85°C, with a pressure rating of up to 1.0 MPa.
In terms of application scenarios, its “dual-water-channel” structure boosts heat dissipation efficiency by 80% compared to conventional single-water-channel designs. At the same time, optimized convection space helps reduce energy consumption, making it ideal for centralized heating systems in residential buildings, schools, and other similar settings. The surface is coated with an electrostatic spray process that forms a protective layer measuring 0.6–0.8 mm thick, striking a balance between aesthetics and durability. It’s worth noting that in individual-household heating applications, products of the “slender, tall, flat-plate” type should be avoided, as they have higher requirements for water pressure and may compromise boiler compatibility. Regular cleaning and ventilation maintenance can further extend the product’s service life.
