      The difference of electronic radiator from the material       

      Electronic radiators are the largest producer and major application country of heating radiators in my country. There are many types of radiators. They are divided into five types: steel, cast iron, aluminum, copper and plastic in terms of materials. Plate type, airfoil type, column airfoil type, plate airfoil type, flat tube type, string fin type, fin tube type, convection type, composite type, combined type, etc.

      Energy conservation and environmental protection were issues that the whole world paid attention to at that time. my country's economy continues to develop at a high speed, and the goal of building energy saving is 50%. Some large cities like Beijing even require building energy saving of 65%. my country's heating energy consumption is now very large, about three times that of developed countries, and the energy-saving application of new radiators has attracted great attention. Now look at the characteristics of various radiators in my country from the perspective of energy saving and environmental protection.

      From the material point of view, good thermal conductivity, fast heat dissipation, high thermal efficiency, and relatively energy-saving. The order of uneven thermal conductivity of various materials is: copper, aluminum alloy, cast aluminum, steel, cast iron, stainless steel, and plastic. In terms of thermal efficiency, copper is the best, aluminum is the second, steel is the best, and plastic is the worst.

      In terms of production conditions, products with simple process, mechanization, high degree of automation, and low energy consumption are energy-saving. The production process of cast iron radiators is messy, and the total energy consumption is high. The production process of steel electronic radiators is simpler, mechanized, and highly automated, with low total energy consumption and low cost.

      From the perspective of the metal heat intensity target, the number of energy savings is high. Metal thermal strength is the heat dissipation of metal per unit mass per unit temperature of the radiator under standard inspection conditions. The unit is W/KG°C. It is a technical and economic goal that reflects material saving and energy saving. Different materials and methods have different metal thermal strength values. Cast iron is 0.3-0.4, steel is 0.8-1.0 or more, aluminum is 1-3 or more, aluminum is the best, steel is the second, and cast iron is the worst.

      The equipment thermostatic control valve can regulate the room temperature and save energy by more than 20%. The equipment thermostatic valve should use a radiator with fast heat dissipation and high thermal efficiency, otherwise the control is not effective and it is difficult to achieve a constant temperature.

   From the perspective of the water capacity of the radiator, the radiator with a small ratio of water capacity to heat dissipation can save 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 save energy.
