The part of the copper-aluminum composite radiator that is in contact with water, that is, the water channel, is all made of copper pipes. The aluminum material and the copper pipes are closely combined to have efficient and stable thermal conductivity. So, which of the top ten brands of copper-aluminum composite radiators is better and how to identify the quality? Let’s follow Jinjin to find out.

The copper-aluminum composite radiator is a convection radiator made of a combination of copper pipes and aluminum materials. Its appearance is beautiful and elegant. The part of the radiator that is in contact with water, that is, the water channel, is all made of copper pipes. The aluminum material and the copper pipes are closely combined to have efficient and stable thermal conductivity. The function of aluminum is to expand the heat dissipation area of ??the radiator and improve the heat dissipation effect. Since the water channels in the radiator are all made of copper pipes, they have strong resistance to oxidation and corrosion and are suitable for almost all heating systems.

How are copper-aluminum composite radiators produced? What is the production process like?

1. The copper-aluminum composite radiator is cut according to the size and quantity required by the customer. It is made of TP05 type 99.9 copper tube and aviation aluminum profile, and is made by hydraulic expansion joint, so that the copper tube and The aluminum profiles are integrated and there are no gaps.

2. Drill holes in the main pipe to connect the branch pipes and the main pipe during installation, and weld the water inlets and outlets at both ends of the radiator. Then treat the water outlet.

3. Weld the branch pipe to the main pipe, assemble the radiator as a whole, and then perform spot welding and assembly welding.

4. Shape the radiators welded together to avoid unevenness or loose connection during the assembly process.

5. Perform a pressure test on the assembled radiator.

6. After the pressing is qualified, surface grinding, spraying and other processes will be carried out on the entire set of radiators.

7. The last step is quality inspection, labeling, packaging and leaving the factory.

How to identify the quality of copper and aluminum radiators?

The quality of a copper-aluminum composite radiator is mainly determined by the copper content, wall thickness, thickness of the aluminum profile, polished smoothness, welding points, etc. From material selection to process, every step is related to the product. quality. The raw material of the copper-aluminum composite radiator is made of aviation-grade aluminum profiles, which has high hardness, fine and uniform surface, and is gentle and not hot to the touch. The copper tube is an electrolytic copper tube with a purity of 99.9. It has high purity, no impurities, and strong plasticity. It is more suitable for metal expansion joints of copper and aluminum composites.
