What is the quality and thermal efficiency of Nord mild steel and copper aluminum composite radiator

Methods for judging the quality of radiators:

Radiator surface spraying: gloss, color, smoothness. First of all, when we buy a radiator, we must look at whether the surface paint of the radiator is shiny and whether the color is pure and bright; Whether the surface solder joints are obvious or not, you can use your hands to touch the surface to judge whether it is smooth.

Radiator anti-corrosion: pay attention to the use of various materials of radiator environment, so the radiator anti-corrosion is more critical, here, the user is best to see the cross-section sample product anti-corrosion, at the same time touch the inside is smooth, if rough means that the anti-corrosion is not done well, or some are painted will fall off the paint, you can buckle the nail to see if it is easy to fall off.

Radiator heat dissipation problem: compare different brands, the same model, the same specification of the product, look at its width, the wider the width, the better the heat dissipation.

Radiator material: Radiators are made of different materials and have different characteristics, such as steel radiators, which are available in a variety of steel types. However, the general radiator material is difficult for users to identify.

Radiator after-sales problems: buy things to shop around, especially after-sales problems, compare the service of each merchant, and then look at the product warranty period, how to deal with after-sales.

A very low-end brand, which has begun to be packaged in the past two years,

copper-aluminum composite radiator; Advantages of copper-aluminum composite radiator: aesthetics, anti-corrosion and heat dissipation are excellent, mainly used in the northern market and the high-end market, as well as in areas with poor water quality and the market with gas wall-hung boiler as the heat source. It has become the mainstream of mid-to-mid-range engineering and retail in the northern market.

Due to the quality problems of steel column radiators produced by some manufacturers in the process of use, people's recognition of copper-aluminum composite radiators is still increasing.

The radiator of the Vera radiator is good, the response of the residents used has been good, beautiful and generous, the color of the heating for several years is still very bright, not old at all, and the heat dissipation effect is the same as when I first bought it, and there are few quality problems. There is also a professional installation and maintenance team.

Mild steel radiator: It is a steel radiator, but the material used is steel with a relatively low carbon content, which is formed at one time after pressing.

Advantages of mild steel radiator: stable quality, good heat dissipation and thermal performance, high pressure resistance. Disadvantages: relatively heavy, because of the strong hardness of carbon steel, it is not easy to shape, less shape, and single color.

Advantages of copper-aluminum composite radiator: good air tightness, good thermal conductivity, strong resistance to alkaline water corrosion, large heat dissipation, high pressure capacity, light weight, long life, novel and beautiful appearance, easy installation, simple maintenance and cleaning.

Disadvantages of copper-aluminum composite radiators: short service life, poor thermal conductivity and air tightness after long-term use, **high, because composite materials ** are very high.

It's too obvious, low carbon steel ** is much cheaper, easy to rust, not good-looking, average heat dissipation, and it's almost the same after two years of use.

Copper-aluminum composite, high, excellent heat dissipation, durable, and beautiful appearance.

Whether it is self-heating or central heating, the radiator material is determined by the water quality, the copper and aluminum composite radiator is good where the heating water quality is unbalanced in the acid-alkali balance, and the steel radiator is good in the place where the heating water quality is relatively stable.

1. Analysis of copper-aluminum composite radiators

Copper-aluminum composite products have good anti-corrosion performance. This kind of radiator is a new type of high-efficiency and energy-saving heating radiator that makes copper tubes and aluminum wing profiles into heat dissipation elements with precision pressurization process. The heat medium flows in the copper tube and does not come into direct contact with the aluminum, so it has a longer service life.

Due to the excellent thermal conductivity of copper and aluminum, the thermal efficiency is very high. However, due to the different thermal expansion coefficients of copper and aluminum, the two metals that are next to each other at the beginning will slowly separate after long-term use, and there will be a gap in the middle, and air will run in, which will slowly reduce the heat dissipation performance of the copper-aluminum composite radiator, and the thermal conductivity will become worse and worse.

2. Analysis of steel radiators

Steel radiators, also known as mild steel radiators, have two types: steel plate radiators and steel column radiators. Steel radiators have the characteristics of large water storage, strong pressure resistance, stable heat dissipation function and high strength. The disadvantage of steel radiators is that they are easy to corrode and cause water leakage accidents.

Steel radiators have more solder joints, and the probability of water leakage is greatly increased compared with other types of radiators.

3. Comparison of steel and copper-aluminum composite radiators**

The material used in the copper-aluminum composite radiator is the most expensive copper, and the steel radiator is generally made of mild steel, so relatively speaking, the copper-aluminum composite radiator is higher than the steel radiator.

Fourth, the comparison of the warranty period of steel and copper-aluminum composite radiators

Steel radiators on the market are guaranteed for 5-10 years, and copper-aluminum composite radiators are guaranteed for 20-30 years.

The quality of copper-aluminum composite radiators is better.

Radiator service life comparison:

Copper-aluminum composite radiator, under the condition of high alkalinity water quality, if the annual corrosion rate is analyzed by year, it can have a corrosion resistance period of 50 years, leaving sufficient room under this condition, and the service life of the radiator can also be guaranteed to be more than 30 years.

Steel radiators, if used in the heating water quality that meets the requirements of the national standard "Water Quality of Heating and Air Conditioning System", have a service life of more than 20 years. If the dissolved oxygen in the water exceeds the standard and the maintenance of the steel radiator cannot be fully maintained during the non-heating period, the life of the steel radiator may be reduced due to oxygen corrosion.

Comparison of radiator heat dissipation performance:

Steel radiators and copper-aluminum composite radiators are very efficient in heat dissipation, and they are a new type of radiator vigorously promoted in China. The metal thermal strength of Rubens copper-aluminum composite radiator is higher than that of steel radiator; The water capacity of the steel radiator is greater than that of the copper-aluminum composite radiator, and the heat is slow, and the cool is also slow, which is professionally called thermal inertia. The copper-aluminum composite radiator heats up quickly, which is more suitable for intermittent heating, and once the central heating heat metering is implemented, it has more advantages.

Radiator decorative comparison:

The steel radiator is strong and straight, has masculine beauty, and can be high and low; The copper-aluminum composite radiator has copper inside and aluminum outside, which is relatively soft, relatively easy to bump and deform, and can also have high energy and low energy. Both have smooth and bright surfaces.

Radiator** Comparison:

The heat price of copper-aluminum composite radiator is slightly higher than that of steel radiator, and the steel finned tube convection radiator in steel radiator is the lowest heat price of a radiator at present.

Introduction of steel radiators:

Mild steel radiator is what we commonly call steel radiator, which is one of the mainstream radiators now. There are two types of steel radiators: steel plate radiators and steel column radiators. The steel radiator has a beautiful appearance, many selectivity, stable heat dissipation performance, low carbon and energy saving, green environmental protection, and is trusted by the majority of users.

The appearance of the steel radiator is beautiful, and the radiator shape, color, center distance, etc. can be customized according to the different needs of users, so it is deeply liked by the majority of users.

Introduction of copper-aluminum composite radiator:

Copper-aluminum composite radiator is a new type of high-efficiency and energy-saving heating radiator that makes copper tubes and aluminum wing profiles into heat dissipation components with precision pressurization process. It is a new product promoted by the state, and it is a replacement product of traditional cast iron radiators.

The copper-aluminum composite radiator has a noble and elegant shape, excellent heat dissipation performance, high pressure-bearing capacity, and the heat medium flows in the copper tube without direct contact with aluminum, so it has a longer service life.

The two materials of the radiator have their own advantages, the gold flagship tips copper aluminum composite radiator is combined with the corrosion resistance of copper, the fast heat dissipation performance of aluminum, but its ** is high, the hardness of aluminum is not high, and some places are not applicable, which may deform it; The steel material of low-carbon steel itself has the characteristics of oxidation and corrosion, so it is necessary to use low-carbon steel radiators with good anti-corrosion, which have good thermal insulation performance, high pressure bearing and hardness, and are suitable for central heating, but should not be used in places with poor water quality.

The copper and aluminum radiator has a good heat dissipation effect, but it is high.

Steel radiators dissipate heat not as quickly as copper and aluminum. Cheap though.

Let's choose according to one's situation. (Steel is recommended for central heating, copper and aluminum are recommended for self-heating.) ）

Which is better, mild steel radiator or copper aluminum radiator? My home is a district central heating, is plumbing, the pipeline line is a look at you just don't understand, first, if you use a radiator, you don't need a water divider, the water divider is used for floor heating,

Copper and aluminum composite is good, steel is easy to corrode, the requirements for water quality are very high, even if the anti-corrosion will be leaked after a few years, and the maintenance must be full of water maintenance

Compared with light steel radiators and cast iron radiators, copper-aluminum composite radiators are made of copper with strong corrosion resistance, which is very safe and reliable, and has the characteristics of corrosion resistance, long life, fast heat transfer, high pressure, environmental protection and energy saving, beautiful appearance, easy installation and maintenance, etc., and is one of the energy-saving heating radiators recommended by the Ministry of Construction.

Steel radiators, also known as mild steel radiators, can be divided into: steel plate radiators and steel column radiators. Steel radiators have the characteristics of large water storage, strong pressure resistance, stable heat dissipation performance, and high strength, which can bring a more comfortable feeling.

As for which one is better, it is relative, it depends on the heating water quality, heating method, procurement budget, etc. to choose the material, and the suitable one is the best.

What are the advantages of copper-aluminum composite radiators? Are copper-aluminum composite radiators good? Is the copper aluminum composite radiator ***?

For home use, is the copper-aluminum composite radiator good? Are copper-aluminum composite radiators safe? 1. Anti-corrosion in high-quality pipes, suitable for heating systems of various water quality, no need for full water maintenance, safe and reliable, and long service life; Second, the heat dissipation is good and the temperature rises quickly, the steel pipe and the aluminum profile are closely combined, there is no gap, the thermal resistance efficiency is high, the heat conduction is fast, and the temperature rises rapidly; 3.

The copper-aluminum composite radiator is produced by using oxygen-free copper pipe as the waterway and aluminum alloy heat dissipation fin through hydraulic expansion technology. In this way, the copper waterway avoids the characteristics of poor anti-corrosion ability of other materials, and the aluminum alloy heat dissipation fin reduces the shortcomings of copper being expensive and soft, so that the advantages of these two materials can be effectively exerted; Therefore, the advantages of copper-aluminum composite radiator are high thermal efficiency, fast heating speed, light weight, strong anti-corrosion ability, and the service life can reach more than 30 years; The disadvantage is that it is still higher than other radiators, but if it is calculated according to the warranty period of the radiator family, the steel radiator is guaranteed for five years, and the copper-aluminum composite radiator is guaranteed for 20 years, which is four times that of steel, and the ** is only more than double that of steel, so on average, the ** of copper and aluminum composite radiators is not high, so it is the most cost-effective radiator among all radiators, which is naturally very good.

Regarding the copper-aluminum radiator, the inner tube of the copper-aluminum composite radiator is made of brass, and the outer tube is aluminum, and the two are closely bonded through the process. When heating, copper and aluminum radiators dissipate heat in the form of convection and radiation.

On the one hand, foreign countries have their own aesthetics for the appearance of radiators, and the purchase of radiators in their decoration is mostly industrial style, and the radiator material prefers steel or cast iron, and the shape is more rough and the metal wind is obvious. The shape of copper and aluminum radiators is mostly simple and gentle.

On the other hand, most of the foreign families are villas or high-rise buildings, the water pressure is generally high, and the pressure-bearing capacity of the copper-aluminum composite radiator is generally, and it is easy to burst under such high water pressure heating.

Advantages of using copper and aluminum for radiator heating:

1. Super corrosion resistance and heat dissipation ability.

The inner wall of the copper-aluminum composite radiator is made of brass, which has good corrosion resistance, and the radiator is not easily affected by other water quality and environment. The outer wall is wrapped in aluminum, which has an advantage in heat dissipation.

The design of copper and aluminum radiators is highly artistic, the pursuit of beauty, to meet the requirements of various decoration styles, due to the characteristics of its production materials, higher value retention.

3. Long life and durability.

Due to the high stability of brass material in long-term contact with heating water, it is more durable when used, and the service life is higher and longer than others, and it can be used for at least forty or fifty years.

Disadvantages of copper and aluminum radiators:

Its big disadvantage is that the heat dissipation effect is easy to attenuate. Because the copper-aluminum composite radiator is made by forcibly laminating the two materials through the process, the performance of itself is different, the longer it is used, the material may be peeled off, the void becomes larger, and the heat dissipation effect will be attenuated.

Copper-aluminum composite radiators have become the choice for purchasing radiators due to their lighter weight, non-corrosive, and suitable for all water quality and heating methods.

The following takes the Rubens copper-aluminum composite radiator as an example to give you the best advantages.

From the material point of view:

Rubens copper-aluminum composite radiator is made of pure copper steel pipe and aviation-grade aluminum precision expansion, the two materials play their own advantages, so that the radiator has stronger pressure resistance and better thermal efficiency and energy saving, so that the heat dissipation effect can be achieved better.

Aesthetics:

The copper-aluminum composite radiator is beautiful and fashionable in appearance, and the body shape is more simple and dexterous than the radiator such as cast iron, the surface coating is smooth and delicate, and there are different colors to choose from.

From the point of view of service life:

The copper-aluminum composite radiator is manufactured with advanced patented technology of flanging hydraulic expansion joint, and the precise process parameters can completely eliminate the gap between the copper pipe and the aluminum profile pipe. The connecting box pipe and heat dissipation pipe through which the radiator heat medium flows are all copper pipes. Pure copper steel pipe is responsible for water walking, aluminum profile is responsible for heat dissipation, pure copper itself has high compressive resistance, high acid and alkali corrosion resistance, no need to do anti-corrosion treatment, adapt to a variety of different water quality, do not worry about water leakage, leakage points and other phenomena due to corrosion.
