A, the classification of radiator
According to different materials, radiators can be divided into cast iron radiators, steel radiators, aluminum alloy radiators, copper-aluminum composite radiators, steel-aluminum composite radiators and copper radiators. According to different manufacturing processes, radiators can be divided into integral die-casting radiators and split radiators.
1, steel radiator:
The radiator made of this material has high pressure, beautiful appearance and high cost performance. However, it is worth noting that steel radiators have high requirements on the water quality of heating systems, and are prone to corrosion when used in heating systems with poor water quality. If the oxygen content in the water is high, the steel radiator is easy to corrode and leak. Therefore, in general, steel radiators are more suitable for residential residents with good water quality. Do not use steel radiators when the heating water quality is not up to standard. But now some big brands have strengthened anti-corrosion treatment, adopting internal and external dual anti-corrosion technology, effectively enhancing the anti-oxidation and corrosion resistance of radiators, thus making the service life of products longer. In addition, after the heating period, the steel radiator needs full water maintenance to prolong its service life.
2. Copper-aluminum composite radiator;
If the water quality in the community is poor, it is recommended that you use copper-aluminum composite radiator, which is light in weight and super corrosion-resistant. The copper-aluminum composite radiator has the advantages of both copper and aluminum. Water flowing in the copper tube will not cause corrosion, but heat can be fully volatilized from the aluminum wing. This radiator has a long service life and a 30-year warranty. Overall, the copper-aluminum radiator is cost-effective. In addition, after the heating period, the copper-aluminum radiator does not need full water maintenance and is easier to take care of.
Second, the heat dissipation effect of different types of radiators.
Radiator is a common heating equipment in winter. Radiator is a combination of radiation heat dissipation and convection heat dissipation, which is not too dry and the temperature rises rapidly. The expected temperature can be reached within 20 minutes after opening, which is energy-saving, environmentally friendly and durable.
Under the premise of the same specifications and environment, the heat dissipation effects of different types of radiators are as follows: aluminum alloy radiator >; Copper-aluminum composite radiator >: steel-aluminum composite radiator >: steel radiator >: cast iron radiator.
Three: the price of different types of radiators
Price comparison of radiator with the same specification: copper-aluminum composite radiator >; Steel-aluminum composite radiator >: aluminum radiator >: steel radiator >: cast iron radiator.
Four: the service life of different types of radiators
Under the premise of the same specifications and environment, the service life of different types of radiators is as follows: copper-aluminum and steel-aluminum composite radiator >; Steel radiator >: aluminum radiator >: cast iron radiator.
Five: Corrosion resistance of different types of radiators
On the premise of the same specifications and environment, the corrosion resistance of different types of radiators is as follows: copper-aluminum and steel-aluminum composite radiator >; Aluminum alloy radiator >: steel radiator >: cast iron radiator.
6. Market share of different types of radiators
With the continuous progress of radiator manufacturing technology, steel radiator and copper-aluminum composite radiator are more and more accepted and used by people because of their good thermal conductivity, portability, aesthetics and high cost performance. After so many years of development, the steel and copper-aluminum composite radiator has reached a perfect height in terms of manufacturing technology, product appearance, service life and consumer recognition. At present, consumers who use steel and copper-aluminum composite radiators account for more than 90% of the total consumption, while the market share of aluminum alloy radiators is getting less and less, and cast iron radiators are almost negligible.
VII. Comparison between integral die-casting and split die-casting radiators.
In China, the usage of split die-casting radiator is greater than that of integral die-casting radiator. The best-selling radiators with a center distance of 600- 1800 mm on the market are almost all split. Because the split radiator can meet the personalized and differentiated needs of customers.
VIII. Comparison of using efficiency between integral radiator and split radiator
Water leaks. Integral radiators generally do not leak water, and split radiators rarely leak water with the development of technology, which can be said to be almost zero. Because the water channel of the former split radiator is oval, the heat dissipation effect is good, but as the radiator expands when heated and contracts when cooled after passing through the water, the oval pipeline is easy to expand and deform due to uneven stress, resulting in water leakage at the interface of the split radiator.
Nine: Anti-flicker when buying
1. 1. Understand the heating water quality of the residential area and choose the radiator material suitable for the water quality. Household heating requires high water quality, so copper-aluminum composite radiator is selected, and steel radiator is suitable for central heating.
2. Secondly, look for the professional products of the top ten brands of radiators made of this material, and please pay attention to beware of counterfeit and shoddy products. Consumers will be confused when choosing radiators. There are dozens of radiator brands in the building materials market, but there is no uniform standard on how to choose them. Only listen to the introduction and screening of sales staff.
The radiator will get darker if used for a long time. If some consumers use colored radiators for a long time, such as red, blue, yellow and so on. They must take into account that the color will get darker after a period of use. If you are afraid of affecting the interior decoration effect, Bian Xiao suggested choosing white radiator as far as possible.
Ten: three points for product and seven points for installation.
Radiator installation is a technical activity, but also has certain risks, involving family property and personal safety. Therefore, Bian Xiao reminded the buyer that the installation must be completed by a professional construction team.
