First of all, talk about the old cast iron radiator. This radiator is made of cast iron, and its surface is usually coated with a layer of paint, which has certain corrosion resistance and durability. It is characterized by slow heat dissipation, but the heat dissipation effect is relatively stable, which can keep the indoor temperature relatively stable. In addition, the shape of cast iron radiator is relatively simple.
However, the old cast iron radiator also has some shortcomings. First of all, it is cumbersome and troublesome to install. Secondly, due to the slow heat dissipation, it takes a long time to heat the room to a suitable temperature, which may not be suitable for some occasions that need rapid heating. In addition, the heat dissipation efficiency of cast iron radiator is relatively low, and it needs a large area to meet the heating demand of the room.
The early radiator was immature, and the radiator was mostly cast iron. This kind of traditional radiator is cheap and can meet the needs of home heating users for a period of time. However, with the development of radiator technology, people pay more and more attention to household heating, and the requirements for heating are not the same. Many problems of traditional radiator are exposed, and the appearance of new radiator meets the personalized needs of home heating, greatly improving the effect and service life of home heating.
Next, let's talk about the new radiator. The new radiator usually adopts copper-aluminum composite, low carbon steel and other materials, which can dissipate heat quickly and heat the room to a suitable temperature quickly. In addition, the shape of the new radiator is relatively simple, which can match the modern home style and increase the aesthetic feeling of the room.
1. Copper-aluminum composite radiator
Copper-aluminum composite radiator is a new type of composite radiator, which is composed of copper tube and aluminum profile by hydraulic tube expanding technology. Combine the two materials and give full play to their respective advantages. Copper tube has good corrosion resistance, and both copper and aluminum have excellent thermal conductivity, which makes the radiator have excellent heat dissipation performance and strong corrosion resistance.
This kind of radiator is expensive, with long service life and high cost performance. At present, the copper-aluminum composite radiator has been loved by more and more users, especially the individual heating users.
2. Steel radiator
Steel is the most widely used material for radiators, and it is also the best-selling material in the market, which is divided into tube and plate. At present, we use tube, which has good heat dissipation performance, elegant appearance and convenience; Plate is not as good as cast iron in heat dissipation, but it is a little more beautiful in appearance, but a little heavier than tube. It is an overheating tool between cast iron and new tube radiator, but the disadvantage of steel is that it is afraid of oxygen corrosion. If it is not anticorrosive, it must be maintained with water.
In view of the problem that traditional steel radiators are easy to be oxidized and corroded, some enterprises have developed an upgraded product-anti-corrosion King Kong. Introduction of anti-corrosion king kong: anti-corrosion king kong 6030F is a patented product. It is a subversive steel radiator, with steel cost performance and corrosion resistance much higher than that of ordinary steel radiators. Anti-corrosion King Kong 6030F radiator adopts special Mg-Al alloy installed at the bottom of steel radiator, and the active Mg-Al alloy first reacts with ions in water to avoid "under-scale corrosion" and "bottom metal corrosion". The consumption time of a magnesium-aluminum alloy is more than 15 years, which greatly prolongs the life of the radiator, does not need full water maintenance, and the warranty period is 15 years.
To sum up, the old cast iron radiator and the new radiator have their own advantages and disadvantages, and which type of radiator to choose depends on the actual situation. The new radiator mainly includes steel radiator and copper-aluminum composite radiator. Copper-aluminum composite radiator is recommended for general household heating, which is the most cost-effective radiator type for household heating. But no matter which type of radiator you choose, you need to pay attention to the quality and installation quality to ensure the use effect and safety.
