What is a copper-aluminum alloy radiator
Copper-aluminum composite radiator is a kind of copper channel radiator, which mostly adopts "double channel" mode. Although the thickness of the radiator increases, the heat dissipation effect is more ideal. The heat dissipation of three-dimensional dual-channel radiator is 80% higher than that of traditional single-channel radiator; The optimized convection space reduces the consumption and resource consumption under the same heat dissipation.
Advantages of copper-aluminum composite radiator
1. Economy and decoration
Because of the excellent thermal conductivity of copper and aluminum, the heat dissipation capacity of copper-aluminum radiator is much higher than other materials, and its heat-price ratio is also much higher than other materials. Because both copper and aluminum belong to non-ferrous metals, their value increases with time, so the preservation rate of copper-aluminum composite radiator is much higher than other radiators.
2. Comprehensive mechanical properties
Aluminum alloy profiles are widely used in China's construction industry because of their high strength, good water tightness and air tightness, good thermal conductivity, beautiful appearance and simple processing. Especially its good thermal conductivity has attracted the attention of many radiator manufacturers in recent years.
3.？ Corrosion resistance of alkaline water
The copper-aluminum composite radiator is manufactured by advanced patented technology of hydraulic expansion joint with internal flanging, and the precise process parameters can completely eliminate the gap between copper pipe and aluminum profile pipe. The main pipe and radiator pipe through which the radiator heat medium flows are all copper pipes, which have strong corrosion resistance and do not need internal treatment. Therefore, it has good alkaline water corrosion resistance. At present, the copper-aluminum composite column wing radiator popularized in China can have a corrosion resistance life of 50 years if the annual corrosion rate is 0.005mm/ year under the condition of high alkalinity water quality, and there is enough room under this condition to ensure the service life of the radiator to be more than 30 years.
4. Wide applicability
Copper-aluminum composite plate heating radiator is composed of copper tube and aluminum profile. Aluminum profile and copper tube are closely combined by high pressure expansion of special equipment. Several columns are assembled and welded, and functional decorative pieces are assembled on both sides to form a plate radiator, which is similar in appearance to a steel plate radiator. Compact structure, beautiful appearance, easy cleaning, light weight, high pressure, good heat dissipation effect (radiation and convection), durable, suitable for all heating systems.
Matters needing attention of copper-aluminum alloy radiator
1. The maximum power consumption value in the equipment data cannot be taken in the calculation, and it should be calculated according to the actual situation; The highest junction temperature in the data is generally 150℃, and there is room for 125℃ in the design. The ambient temperature cannot be 25℃ (considering the actual temperature in summer and the chassis).
2. The radiator should be installed in a direction conducive to heat dissipation, and heat dissipation holes should be opened in the chassis or the corresponding position on the chassis (so that cold air can enter from the bottom and hot air can escape from the top).
3. If the shell of the equipment is an electrode, the installation surface is not insulated (not insulated from the internal circuit). During installation, mica gasket must be used for insulation to prevent short circuit.
4. The pins of the equipment should pass through the radiator and drill holes in the radiator. In order to prevent the pin from colliding with the hole wall, PTFE sleeve should be put on.
5. In addition, different types of radiators have different thermal resistances under different heat dissipation conditions, which can be referenced in design, that is, they can be calculated by referring to the thermal resistances of these radiators in practical application, and radiators composed of profiles with similar structural shapes (cross-sectional area and perimeter) can be used instead.
The above is the basic knowledge about copper-aluminum alloy radiator shared in detail. I hope you can better understand the basic knowledge about copper-aluminum alloy. Radiators are very common in our daily life, and copper-aluminum alloy radiators are widely used in all walks of life. It is conceivable how important the copper-aluminum alloy radiator is. The copper-aluminum alloy radiator we shared above is also very detailed. I hope you can pay close attention to what we also share. At the same time, I hope our sharing can help more friends.
