Which material of radiator works better? The copper aluminum composite seems to be relatively light,

Copper and aluminum are good conductors of electricity and heat, and copper and aluminum radiators dissipate heat quickly, thoroughly and efficiently.

Copper and aluminum radiators** are much more expensive. Long service life.

The heat dissipation effect of copper-aluminum composite is fast, but it is also cool, and the thermal insulation performance of steel is good but cool. Copper and aluminum generally have a high copper content and are suitable for areas with hard water quality. In general, if your home is district heating, you can choose a steel radiator because it is constantly heating and the steel is cheap and cost-effective.

If you are independent heating, that is, wall-hung boiler + radiator, it is recommended that you choose a copper-aluminum composite, so that the heat dissipation is fast, more energy-saving and comfortable, of course, if you have someone in your home during the day, you can also use steel, it is recommended to use a better Sender's category. The radiator with a better anti-corrosion effect is Sende and Xu Jinuan's.

The appearance of steel is beautiful, but it is afraid of oxidation. The copper-aluminum composite radiator has high pressure-bearing capacity, good heat dissipation effect and good anti-corrosion effect. Further information can be found on the Oldenberg website.

Steel, the more corners cut the heat dissipation effect better, copper and aluminum because it is composite heat dissipation, so it must be a good pipe expansion technology, that is, if you see that the copper pipe and the aluminum profile is not tight or there is a gap, it will definitely not work. If the inlet water temperature can reach 60 degrees, it is recommended to use copper and aluminum composites. 70 degrees for optimal heat dissipation.

The heat dissipation of copper-aluminum composite is fast, and there is no maintenance, and the anti-corrosion effect is good. But it's also relatively expensive.

As an important heating equipment, the country has perfect standards and quality requirements for radiators, but the national standards can only determine whether the quality of the radiator is qualified, and what kind of radiator is more suitable in different situations? Next, Shandong radiator manufacturer Ruihuate will take you to compare radiators of various materials in multiple dimensions.

At present, the radiators on the market are mainly divided into: cast iron radiators, mild steel radiators, copper-aluminum composite radiators, bimetallic die-cast aluminum radiators and so on.

In terms of heat dissipation effect, copper-aluminum composite radiator is relatively the best, after all, the combination of aluminum profile and copper tube, coupled with the fin process, makes it have a great improvement in heat dissipation.

From the ** point of view: steel radiators are relatively the cheapest, this is just relatively Ha, if you say good quality mild steel radiators are not necessarily cheaper than bad other radiators.

In terms of pressure rating, the traditional cast iron radiator is the best, after all, the wall thickness is relatively thick, but if it is steam heating, it is always better to consider it, or to choose a steam-specific steel radiator.

In general, each radiator has its own advantages, and it is also one of the reasons why the radiator market is blooming, but no matter which radiator you choose, it is recommended that you choose a regular manufacturer to buy and avoid buying inferior products.

1. Copper-aluminum composite radiator is one of the modern new radiators, which is made of aluminum profiles and copper pipes through hydraulic pipe expansion process. The heat medium flows through all copper tubes, and the corrosion resistance of copper is very strong, so the corrosion resistance of the radiator is ensured to the greatest extent, which is the biggest advantage of the copper-aluminum composite radiator.

2. Steel plate radiator, its appearance is simple and elegant, the heat dissipation effect is good, and it is more popular in the south. However, the anti-corrosion performance is poor, and it cannot be used in more complex heating systems, such as poor water quality, or a supply and return channel of radiators of different materials, otherwise the service life will be affected.

The above information is collected and sorted out for Rubens radiators for you, I hope it can help you.

Answer 1: The service life of copper and aluminum radiators and steel radiators is different, and the service life of steel radiators can be more than 10 years when used in heating water quality under specific experimental conditions, such as meeting the requirements of the national standard "Water Quality of Heating and Air Conditioning System". However, the water quality in most of the central heating areas is not very good, and the life of the steel radiator may be reduced due to oxygen corrosion during use. Moreover, the steel radiator must be fully watered for maintenance, otherwise the inner wall will also accelerate corrosion.

Due to the factor of radiator raw materials, it directly leads to the copper and aluminum composite radiator** slightly higher than the steel radiator. When buying radiators, you can choose according to the decoration budget.

Will you still choose radiators for home heating? Copper-aluminum composite or steel is better, and the introduction here is very comprehensive.

Copper-aluminum composite radiator. I hope my answer can help you.

First, it is related to the heat dissipation area.

We all know such common sense: the larger the heat dissipation area, the more conducive to heat dissipation, and the copper-aluminum composite radiator makes good use of this principle. From the structural point of view, compared with other types of radiators, the copper-aluminum composite radiator has a unique design, generally adding heat dissipation fins on the back, increasing the heat dissipation area by more than 20%, and the top buckle design is conducive to heat dissipation, so that the radiator heat dissipation is more rapid.

Second, it is related to the water temperature of the system.

Copper-aluminum composite radiators are mostly used in closed heating systems, using water as a heat carrier, connected through pipes, and finally relying on radiators to output a suitable temperature. It can be seen that the heat dissipation effect of the radiator depends largely on the temperature of the inlet and outlet water. For self-heating users, the water temperature of the system can be freely controlled by adjusting the water temperature of the wall-hung boiler, so that the room temperature can be controlled in the most comfortable state.

Third, it is related to the material.

After scientific determination, the order of metal thermal conductivity from large to small is: copper (401w aluminum alloy (237w steel (80w stainless steel (w, the greater the thermal conductivity, the better the thermal conductivity. The copper-aluminum composite radiator uses copper and aluminum as raw materials, which has good thermal conductivity, large heat dissipation, rapid heat dissipation, and low-carbon and energy-saving.

Fourth, it is related to the thermal insulation performance of the room.

When heating in winter, we will find that although the same radiator products are used, some users have a high temperature in their homes, while others are low, which is mainly caused by the different thermal insulation properties of the room. If the insulation effect of the room is not good, a large amount of heat will be lost outward, and a large amount of cold air from the outside will flow into the room, resulting in insufficient heat load in the room, and the room temperature will not reach the ideal temperature.

It's okay. The heat dissipation of copper-aluminum composite radiators is not much worse than that of steel radiators, and it feels good to use, and there is no problem.

1. Comparison of the service life of radiators.

China is now promoting the production of copper-aluminum composite radiators, under the condition of high alkalinity water quality, if the annual corrosion rate is analyzed annually, there can be 50 years of corrosion resistance, leaving sufficient room under this condition, but also to ensure the service life of the radiator more than 30 years.

If the steel radiator is used in the heating water quality that meets the requirements of the national standard "Water Quality of Heating and Air Conditioning System", the service life is 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.

2. 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 gold flagship 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.

3. Comparison of radiator decoration.

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.

Fourth, radiators** comparison.

The heat price of copper-aluminum composite radiator is slightly higher than that of steel radiator, and steel radiator convection radiator is a kind of radiator with low heat price at present.

Which is more practical than copper-aluminum composite radiator or steel radiator? Kiss! Hello, glad to answer for you.

Copper-aluminum composite radiator is more practical 1, the heat dissipation performance is more efficient than that of steel radiators and copper-aluminum composite radiators, and it is a new type of radiator vigorously promoted in China. The metal thermal strength of 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. Copper-aluminum composite radiators heat up quickly and are more suitable for intermittent heating.

2. Compared with the copper-aluminum composite radiator that China is now promoting and producing, under the condition of high alkalinity water quality, if the annual corrosion rate is analyzed annually, it can have a corrosion resistance of 50 years, leaving sufficient room under this condition, and can also ensure the service life of the radiator for more than 30 years. If the steel radiator is used in the heating water quality that meets the requirements of the national standard "Water Quality of Heating and Air Conditioning System", the service life is more than 20 years. If the dissolved oxygen in the water exceeds the standard and the maintenance of the water is not full during the non-heating period, the life of the steel radiator may be reduced due to oxygen corrosion, so it is recommended that the copper and aluminum composite radiator should be selected as much as possible in the place where the heating water quality is not good.

3. **Compared with copper-aluminum composite radiators**, slightly higher than steel radiators; According to the service life, copper-aluminum composite radiators are more cost-effective than steel radiators. 4. The decorative steel radiator is strong and upright, and the side school has masculine beauty, which can be high and low; Copper-aluminum composite radiator inner copper and outer aluminum, soft atmosphere, can also be high energy and low; Both are beautiful on the surface. Hope mine can help you!

Do you have any other questions?

The copper-aluminum composite radiator is mainly made of oxygen-free copper pipe as the water pipe, and the external aluminum profile is used as the heat dissipation profile, and the two are closely bonded through the process to achieve effective heat dissipation effect. When heating, copper and aluminum radiators dissipate heat in the form of convection and radiation. Moreover, the shape of the copper-aluminum composite radiator is more simple and gentle, which can fit the modern decoration style.

The advantages of choosing copper-aluminum composite radiators for radiator heating are:

1. Super corrosion resistance and heat dissipation ability.

The copper-aluminum composite radiator uses oxygen-free copper pipe as the water pipe, 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.

2. The shape of the copper-aluminum composite radiator is more beautiful.

Compared with steel radiators, copper-aluminum composite radiators have high artistic design, the pursuit of beauty, meet the requirements of various decoration styles, and have higher value retention due to the characteristics of their production materials.

3. The copper-aluminum composite radiator has a longer service life and is more durable.

Due to the long-term contact with the heating water oxygen-free copper tube, the stability of copper is high, so it is more durable in use, and the service life is higher than others, under normal circumstances, the warranty period of the copper aluminum composite radiator is as high as 20 years, and if the normal use and maintenance are reasonable, it is not a problem to use it for thirty or forty years.

Of course, having said so many advantages of copper-aluminum composite radiators, then there are also disadvantages: the biggest disadvantage is that copper-aluminum composite radiators have very high requirements for the production process of radiator manufacturers, if the production technology is not mature enough, then the copper-aluminum composite radiator will be because of the two materials fit, its own performance is different, the longer it is used, the material is peeled off, the gap becomes larger, and the heat dissipation effect is attenuated.

Are you still struggling to buy copper-aluminum composite radiators? After reading the following reasons for buying copper-aluminum composite radiators, you won't be entangled, let's take a look with Jinjin, copper-aluminum composite radiator advantages:

1) Comprehensive mechanical properties.

Copper-aluminum profiles are widely used in China's construction industry due to their high strength, good water tightness and air tightness, excellent thermal conductivity, soft texture and easy processing. In particular, good thermal conductivity has been paid attention to by more and more radiator manufacturers in recent years.

2) Corrosion resistance.

The copper-aluminum composite heat sink is manufactured by advanced patented technology of internal flanging hydraulic expansion joint, and the precise process parameters can completely eliminate the gap between the copper tube and the aluminum profile tube. The radiator main pipe and heat pipe are all copper pipes. High corrosion resistance. There is no need for internal antiseptic treatment.

3) Economy.

Because the thermal conductivity of copper and aluminum is very good, the heat dissipation capacity of copper and aluminum radiators is much higher than that of radiators of other materials, and its cost performance is much higher than that of radiators of other materials. And because copper and aluminum are non-ferrous metals, its value is increasing with time, so the value retention rate of copper-aluminum composite radiators is much higher than that of radiators of other materials.

Copper-aluminum composite radiator is a new type of radiator commonly used in modern families. The appearance of copper and aluminum radiators is simple and fashionable, and cost-effective, in recent years, more and more home decoration uses copper and aluminum radiators. Let's follow the golden flagship flag brother to find out.

Copper-aluminum composite radiator 7575, made of high-quality copper tube with copper content, 6063 aviation-grade titanium aluminum.

Advantages of copper-aluminum composite radiators:

First of all, copper is also an inert metal from a chemical point of view, with good stability and strong oxidation and corrosion resistance, and the service life of copper-aluminum composite radiators can reach 30 years, while the life of steel radiators is usually about 15 years.

Secondly, copper and aluminum are both metals that conduct heat very quickly, and copper and aluminum are connected by a second-order expansion tube with no gap thermal resistance; In addition, the water capacity is small, so it can heat up quickly.

For intermittent heating, rooms that require rapid heating up, the installation of copper-aluminum composite radiators is very suitable.

Precautions for installation of copper-aluminum composite radiators:

Moreover, the surface of the aluminum profile is smooth and the shape is diverse, such as plane, arc surface, unity column, double waterway;

Compared with cast iron radiators, copper-aluminum composite radiators have a higher height, which can reach 1850mm, which saves space in low places.

The main material of copper-aluminum composite radiator is aluminum, which has low density, light weight and high metal thermal strength, which is 2 times that of steel radiator and 3-4 times that of cast iron radiator.

The light weight reduces transportation costs and is easy to install.
