How to choose a heat sink and precautions

The advent of the renovation season, we should pay attention to what aspects of the problem when purchasing radiators?
First of all, to understand the water quality of the community, is the acid or partial alkali, according to the characteristics of raw materials corrosion: steel afraid of acid, aluminum afraid of alkali, copper afraid of electrolytes, choose their own heat sink material.
Second, to understand the various materials radiator manufacturing process, the steel is usually the formation of the first re-welded steel pipe, there are manual welding and automatic welding points, automatic welding skills are better, the weld closely uniform. Aluminum is divided into aluminum alloy and die-cast aluminum. Aluminum alloy is usually welded automatically. A group of radiators is a whole. It is maintenance-free at a later stage. However, if the amount of heat is not enough, it needs to be replaced as a whole. Each piece of die-cast aluminum is a whole. , And then use the silk thread to connect, there is the possibility of leakage in the later use, but the benefit is that if the heat can not add the number of pieces. At present, the copper-aluminum composite radiator is considered to be the most suitable boiler system in the southern region. It adopts an anti-oxidation-resistant copper tube with an aluminum wing with excellent heat dissipation effect. The flow of water in the copper tube will not cause corrosion, but the heat is Fully volatile radiation can be obtained from the aluminum wing, which is a powerful combination of materials. The copper-aluminum composite radiator overcomes the disadvantages of low cast iron radiator pressure, low metal thermal strength, and poor decorative properties. It also overcomes the poor corrosion resistance of steel radiators and other metal radiators and reduces the need for system water quality. High trouble. Rubens copper-aluminum composite radiator is the best selection of copper tubes (oxygen-free), has a good resistance to alkaline water corrosion, the use of hydraulic expansion tube technology, copper and aluminum are not separated, long-lasting and efficient thermal performance. Twenty years of long warranty, only for repair.
Third, consumers probably know that China is a big country for radiator production, consumption, and export. China's radiator R&D, development, and production skills will never lag behind foreign countries. On the contrary, it is leading in some respects. Imports may not necessarily be adapted to China's heating water quality. The notion that "as long as imports are the best" is not necessarily correct.
Fourth, from the aspect of appearance, there are many types of steel, and the surface is smooth and beautiful. The aluminum and copper and aluminum are of a single style. Because of the reason of the aluminum raw material itself, the appearance is likely to cause bumps.
Fifth, from the perspective of internal anti-corrosion, we must buy a well-known, powerful, advanced equipment manufacturers such as Rubens heating radiators, small workshop-style companies usually not within the anti-corrosion treatment, use less than two years Water leakage and other phenomena will occur.
Sixth, the general running style, silk plugs, expansion nails, hooks, these are the standard parts of the radiator, is provided by the manufacturer free of charge.
In addition, consumers choose the radiator, at the same time to consider the family decoration style, budget expenses and other factors, more than more understanding and more consulting, shop around, choose the real heat sink for their own.
