Common Classification of Electronic Radiator

Apr. 21, 2020

Many people think that electronic radiators look the same, no difference, and they don't know what kind of classification. Today we are going to popularize the little knowledge about electronic radiators. The custom heat sink extrusion suppliers to introduce the common classifications.

In recent years, with the continuous development of the household heat metering technology, the household heating ring setting system has also been widely used in the majority of civil and industrial buildings. Heating layout electronic cooling

According to the material method, the radiator is mainly divided into three types: iron radiator, aluminum radiator, and steel radiator.

1. Cast iron radiator

Cast iron radiators will gradually be eliminated by the market due to their low bearing capacity, large size, rough appearance, and many insurmountable disadvantages such as high energy consumption.

2. Steel radiator

At present, steel radiators are mainly divided into plate type and column type according to style. Especially the steel column radiator, because it is a steel column radiator, with its rich colors and beautiful appearance has won the love of many consumers.

The purchase of steel radiators requires that the voice matches the heating system of the community. Consumers who use open heating systems for heating should choose steel radiators cautiously. Oxygen content in water

Strict requirements require that the main system be filled with water after the heating suit is maintained. If the maintenance is not good, the radiator will quickly repair the corrosion and eventually the radiator leaks.

3. Aluminum radiator

Custom aluminum extrusion large heatsink mainly includes high-pressure cast aluminum and stretch aluminum alloy welding. The main advantages are:

①The heat dissipation of aluminum is better, and the energy-saving features are very obvious. In the same room, if you use the same specifications of warm pins, the number of aluminum castings is less than that of steel.

② Aluminum has good resistance to oxidation and corrosion, without adding any additives. The principle is that once aluminum encounters oxygen in the air, it will form an oxide film. This film is tough and dense, which prevents further corrosion of the body material.

Choose aluminum radiator, choose a high-pressure cast aluminum module combined radiator. This type of radiator is integrally die-casted at one time, so there is no problem with weld leakage. And its biggest advantage is that the product is not limited by the district heating system, even in the open boiler system, it will not be corroded by oxygen. With the continuous development of electronic radiators, the classification of electronic radiators has not only been these three models, but we will also continue to introduce it below!

4. Pure copper radiator

The thermal conductivity of copper is 1.69 times that of aluminum, so under the same conditions as other conditions, a pure copper heat sink can quickly remove heat from the heat source. However, the texture of copper is a problem, and many advertised "pure copper radiators" are not real.

100% copper. In the list of copper, the copper content of more than 99% is called acid-free copper, and the next grade of copper is red copper with a copper content of 85% or less. Most of the pure copper radiators on the market currently have a copper content somewhere in between. And-some inferior

The copper content of the pure copper radiator is not even 85%. Although the cost is very low, its thermal conductivity is greatly reduced, which affects the heat dissipation. In addition, copper also has obvious shortcomings, high cost, difficult processing, and the quality of the radiator is too large, which hinders all copper heat sinks

application. The hardness of red copper is not as good as that of aluminum alloy AL6063, and some mechanical processing (such as profiling, etc.) is not as good as aluminum; the melting point of copper is much higher than aluminum, which is not conducive to extrusion and other problems.

5. Ceramic radiator (also known as a ceramic heat exchanger)

The production process of a ceramic radiator is basically the same as the production process of kiln furniture. The thermal conductivity and oxidation resistance are the main application properties of the material. Its principle is to dissipate the ceramic: the device is placed near the outlet of the flue and at a higher temperature, and does not need to be mixed with cold air and

High temperature protection, when the furnace temperature is 1250-1450 ° C, the temperature of the flue outlet should be 1000-1300 ° C, the waste heat recovery of the ceramic heat exchanger can reach 450-750 ° C, and the recovered hot air is sent into The kiln and the fuel gas form a mixed gas for combustion, which directly reduces production costs and increases economic benefits.

The ceramic heat exchanger has been well developed under the limitations of the use of metal heat exchangers, because it has better solved the problems of corrosion resistance and high-temperature resistance, and has become the best heat exchanger for recovering high-temperature waste heat. After many years of production practice, it shows that the ceramic heat exchanger is effective

The fruit is very good. Its main advantages are well-cooked conductivity, high-temperature strength, good resistance to oxidation and thermal shock. Long life, small maintenance, reliable and stable performance, and easy operation. It is currently the best device for recovering high-temperature flue gas waste heat.

6. Copper and aluminum combined radiator

The combination of these two metals is difficult, and the affinity between copper and aluminum is poor. If the bonding process is not good, it will produce "larger interface thermal resistance (that is, the two metals are caused by insufficient contact between the two Thermal resistance). In actual design and manufacturing, manufacturers

Always reduce the thermal resistance of the interface as much as possible, promote the advantages and avoid the shortcomings, which often reflects the manufacturer's design capabilities and manufacturing process

According to the material, the electronic radiator can be divided into so many types. I believe that in the future, it will be more and more types, and it will be able to better meet our more requirements.
