Can you introduce the copper-aluminum radiator in Tuhan, Inner Mongolia?

Because the northern region is relatively cold, heating is used to help people get through the cold every winter. One of the common heating equipment is radiator, and the popular product on the market at present is copper-aluminum composite radiator. Today we will take a look at the copper-aluminum composite radiator and its shortcomings.

Disadvantages of copper-aluminum composite radiator

Is the copper-aluminum composite radiator good?

Copper-aluminum composite radiator is a new type of high-efficiency and energy-saving heating radiator, which is made of copper tube and aluminum airfoil through precise expansion and contraction process, and its heat dissipation mode is mainly convection. This radiator has the advantages of good heat dissipation performance, high bearing capacity, long service life and high thermal efficiency.

As a kind of high-quality radiator product, steel-aluminum composite radiator has good thermal conductivity because of using copper and aluminum as raw materials, and the heat dissipation performance and energy-saving effect of the material play a decisive role. Scientifically speaking, the order of thermal conductivity of metallic materials is: copper (40 1W/mK), aluminum alloy (237W/mK), steel (80W/mK) and stainless steel (50W/mK). The thermal conductivity of copper-aluminum composite radiator can only be calculated by aluminum alloy, and that of steel-aluminum composite radiator can only be calculated by steel.

Because of the good thermal conductivity of copper and aluminum, the heat dissipation capacity of copper-aluminum radiator is much higher than that of other materials, and its heat-price ratio is also much higher than that of 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.

In addition, copper-aluminum profiles have the characteristics of high strength, good water tightness and air tightness, good thermal conductivity, beautiful appearance and simple processing. Now copper-aluminum composite radiators have been widely used in China's construction industry.

Disadvantages of copper-aluminum composite radiator

1, the thermal conductivity will deteriorate after a long time of use. Because of the different thermal expansion coefficients of copper and aluminum, the two metals that are next to each other at first will gradually separate after a long time of use, and there will be gaps in the middle, and air will come in, which will gradually reduce the heat dissipation performance of copper-aluminum composite radiator and make the thermal conductivity worse.

2. High price: As precious metals, copper and aluminum cannot change their scarcity. All-copper network reminds that with the development of global economy, it is inevitable that the international copper and aluminum prices will rise further. It is precisely because of the price factor that the development of copper-aluminum composite radiator is greatly restricted.

3. The resources of copper and aluminum are limited in the world, and both are non-renewable. In addition to being used in daily life, there is also a wide demand in military and science and technology, which leads to the fact that the amount of copper and aluminum really used in home is not much, and it cannot be produced on a large scale, which is one of the reasons why it does not surpass the steel radiator.
