1. From the perspective of raw materials, it has good thermal conductivity and fast heat dissipation, high thermal efficiency and relatively energy saving. The high thermal conductivity of various raw materials is copper. Therefore, if the thermal efficiency is the norm, the raw materials of the energy-saving radiator should be copper-aluminum composite radiator, steel radiator, and plastic raw materials are not energy-saving.
2. From the perspective of metal thermal strength index, high number of energy saving. Metal thermal strength is the heat dissipation of metal per unit mass per unit temperature of the radiator under standardized test conditions. The unit is W/KG°C. It is a technical and economic indicator that reflects material saving and energy saving. Different raw materials and methods have different metal thermal strength values for radiators. Cast iron is 0.3-0.4, steel is 0.8-1.0 or more, and aluminum is 1-3, which is obvious. Aluminum is better, steel is second, and cast iron is poor.
3. From the perspective of the water capacity of the radiator, the ratio of the water capacity to the heat dissipation is small, and the radiator saves energy. The water capacity is small, the heating and transportation cycle energy consumption is small, the heating is fast, the efficiency is high, and the energy is saved. Steel string fins, steel finned tube convection radiators, and copper tube convection radiators have small water capacity and energy saving. Now some radiators with large water channels are misleading, because they do not save energy.
4. From the perspective of the height of the radiator and the number of assembled pieces, a radiator with not too high fins and few assembled pieces is beneficial for better heat dissipation and energy saving. The column number of column-type radiator should not be too many, 2 columns and 3 columns on one side are better. Too many columns will not save energy. There are too many columns, and each column cannot sufficiently dissipate heat.
5. From the perspective of receiving methods, progress is good. Sometimes the heat dissipation at the lower two ends will drop by 20%.
