Copper-aluminum composite radiator : High load-bearing capacity, good heat dissipation effect, good anti-corrosion effect, long service life, no need for water filling and maintenance after heating season, no risk of alkalization and oxidation, and is more suitable for northern water quality and complex heating systems. But compared with single radiator, it has a very important purpose in industry, and we should be prepared accordingly, so what should we do? In terms of water quality, heating dissolved oxygen in hot water is the main factor of corrosion, and water filling maintenance, deoxygenation measures or adding corrosion inhibitor is necessary.
copper-aluminum composite radiator is a corrosion-resistant radiator, including: upper horizontal pipe, lower horizontal pipe and riser; the bottom surface of the inner wall of the lower horizontal pipe is inclined downward along the two sides to the center, with an inclination angle of 5°; in addition, a sewage outlet is provided at the center of the bottom of the lower horizontal pipe, with a diameter of 50mm, and a valve is provided at the sewage outlet; the upper horizontal pipe, lower horizontal pipe, and front and rear horizontal pipes include: paint layer, copper-aluminum composite layer and polytetrafluoroethylene from the outside to the inside. The copper-aluminum composite radiator has excellent corrosion resistance and light weight.
copper-aluminum composite radiator has a special structure, with copper tubes inside and aluminum sheets outside. The copper tube is responsible for direct contact with water, and the aluminum sheet is responsible for conducting heat to the outside. This structure is a major feature of copper-aluminum composite radiator. In China, the water quality and environment of heating are very different. Generally, metals are difficult to come into contact with water for a long time, and copper is a few easy-to-get metals in nature that have good corrosion resistance. The copper is soft and easy to cast and mold, and is more corrosion-resistant than alloys made of other metals. Bronze Sword is still sharp after thousands of years, which shows the corrosion resistance of copper alloy . Therefore, the inner wall of copper is corrosion resistant, and due to the good thermal conductivity of aluminum, it is used as the outer wall of the radiator.
