In the heating product market, radiator products occupy a pivotal position, occupying most of the supply market. Common radiators on the market mainly include cast iron, steel, copper-aluminum, steel-aluminum, stainless steel, steel fins and so on. Each has its own characteristics and advantages, and of course also has its own shortcomings.
1. Cast iron radiator: Cast iron radiator has a long history in my country, and the biggest advantage is corrosion resistance. Because of its corrosion resistance, long service life and no need for special protection, from the point of view of use, cast iron radiators can truly achieve the same life as the building. Today's cast iron radiators have long since gotten rid of the bulky appearance in people's impressions, and adopted a new process of electrostatic spraying on the surface, making them a representative of high-quality and low-cost products.
However, because of its high energy consumption, serious environmental pollution, heavy weight, poor appearance quality, low pressure bearing capacity, backward production technology, and sticky sand in the inner cavity, it does not meet the requirements of energy saving and environmental protection. The product.
2. Steel tubular radiator: Steel radiator occupies a unique position among many types of radiators due to its good thermal performance, light weight and beautiful appearance, and occupies a share of the home improvement market. Also max.
However, due to the poor corrosion resistance of steel radiators, and the current heating system in my country is not perfect and standardized in many aspects such as design and equipment quality and management, a considerable number of heating systems using steel radiators exist. Serious corrosion problems. Even if the internal coating anti-corrosion process is used to enhance its anti-corrosion ability, the corrosion resistance of the steel radiator is still its weakness. Especially in the non-heating season, most of the heating system is vented for maintenance, which further aggravates the corrosion of the steel radiator. The heating system directly supplied by the coal-fired boiler room should not use steel radiators.
3. Aluminum radiator: Made of aluminum, it is light in weight and has good heat dissipation effect.
However, due to the characteristics of aluminum itself, it is not easy to process and manufacture, and it is not easy to diversify the shape. It is not easy to meet the high requirements for home decoration. There are also certain problems in the welding process. Steel, in order to protect the system, the water quality is generally alkaline, so the aluminum radiator must be internally anti-corrosion, but the internal anti-corrosion quality is difficult to guarantee. In addition, aluminum and other metals are prone to electrochemical corrosion, so they cannot be mixed with steel products and copper products, and the content of copper and iron in water should be strictly controlled.
4. Copper-aluminum composite radiator: copper-aluminum composite radiator is a high-efficiency energy-saving radiator developed according to the development needs of my country's building heating market. Its appearance can be varied and can meet the consumption concepts of different consumers. . It is compact in structure, beautiful in appearance, easy to clean, light in weight, high in pressure, good in heat dissipation (radiation, convection), durable and suitable for all heating systems. The copper-aluminum composite radiator will become the dominant new radiator for a long time in the future because of its outstanding anti-corrosion performance, wide applicability, good thermal price ratio, high value retention rate and beautiful appearance.
However, the cost of copper-aluminum composite radiator is relatively high, and it is a high-end product in the radiator family. It makes many consumers with limited decoration budgets discouraged.
5. Steel plate radiator: It is made of steel and is composed of a water-passing part and a convection fin during manufacture. The water-discharging part is welded by two pieces of rolling-formed whole steel plates, with a large heat dissipation area, no deformation of the plate, and easy welding and forming. The production process is clean and environmentally friendly, the product appearance is beautiful and generous, the decoration effect is good, the pressure bearing capacity is high, and the heat dissipation effect is good, which can effectively save energy and meet the requirements of energy saving and environmental protection.
However, the steel radiator needs to be maintained with full water during the non-heating period. At present, the heating system in some places in China cannot be maintained with full water or the system cannot be maintained with full water due to human reasons.
