What is the working principle of radiator?

The working principle of the radiator is as follows:

The radiator follows the principle of heat transfer and the law of conservation of energy: the temperature of the heated object will not be higher than that of the heat source, otherwise the energy will not be conserved. The temperature of the radiator will reach the same temperature as the hot water in the pipeline at most, and will not exceed the temperature of the hot water.

In actual use, the radiator will radiate heat to the surrounding space, so it will not reach the temperature of hot water in the water pipe below. Some buyers may have questions: How much can the radiator be lower than the water temperature? There are many random factors in this question, which is difficult to determine. It has a lot to do with the temperature of the room, the size of the room space, whether it is closed or not, and the difficulty of heat dissipation. If the room temperature is low, the room space is large, and it is easy to dissipate heat due to poor sealing, the heat of the radiator will radiate to the surrounding space in large quantities, resulting in the temperature of the radiator being much lower than that of water.

Extended data

Generally, the classification of radiators is as follows according to materials:

1, cast iron radiator:

It is an outdated product. However, due to its low cost and good corrosion resistance, especially the inertia of market demand, it will still occupy a considerable share in the low-end retail market and engineering market in the next few years.

2, steel column radiator:

Its advantages are outstanding appearance and good cost performance. It makes the steel radiator rank first in the sales volume and market influence of new household radiators with overwhelming advantages. In terms of production, steel radiator is easy to obtain, reusable, good in production premise and pollution-free, which has become a national key promotion plan. However, due to its corrosion resistance and heat dissipation performance, it is not suitable for use in the case of poor water quality.

3. Steel plate radiator:

The aesthetics and corrosion resistance are not as good as those of steel column radiator, but the price is slightly higher than that of steel-aluminum composite radiator. Mainly in the southern market, its market share has an overwhelming advantage.

4, steel fin radiator:

Because of its poor appearance, it cannot be recognized as the mainstream retail market. Compared with steel insert welding radiator, its price has no advantage, and transportation and installation are a bit troublesome. But its price and corrosion resistance are relatively competitive. Mainly in the low-end engineering market, it still occupies a large market share.
