The first thing to buy a radiator is to look at the quality of the radiator. Good quality can meet your own requirements.

　　 1. The water circulation speed and mode of the radiator.

Because the heating process of the radiator is that the heat brought by the hot water is transferred to the inner wall of the radiator through convection, then the inner wall transfers the heat to the outer wall by heat conduction, and finally the outer wall transfers most of the heat to the surrounding area through convection heat exchange. The cold air transfers a small part to the indoor objects and people through a part of the radiation, completing the entire heat transfer. Therefore, the faster the circulation, the faster the indoor temperature rises, and vice versa! Therefore, the user can choose some large water channel or double water channel radiator when choosing, the circulation flow rate is faster!

　　2, radiator surface area

The surface area of the radiator is also called the heat dissipation area, which is also an important factor that determines the heat dissipation efficiency of the radiator. The same material, the same water temperature, the larger the surface area, the higher the heat dissipation efficiency. Therefore, many manufacturers are now maximizing Increase the heat dissipation area of the radiator.

　　3, the material of the radiator

From the original cast iron to today’s steel and copper-aluminum composite materials, each material update has improved the heat dissipation efficiency of the radiator. Nowadays, there are few manufacturers producing cast iron, but there is still a certain amount of market retention. There are several materials, the heat dissipation efficiency from high to low is: copper-aluminum composite>steel>cast iron, and copper-aluminum composite has strong corrosion resistance, is light and beautiful, and has become the mainstream material of radiators.
