Our country is big country of production of heating radiator and radiator using played, many types, from the material into steel, cast iron, aluminum, copper and plastic in 5, from the form, shape, a column type, column wing airfoil, airfoil, flat tube type, string sheet type, fin tube type, convection type, composite type, combination type. Energy saving and environmental protection is the world 's attention by a large problem. As China's sustained and rapid economic development, the state proposed building energy-saving target of 50%, like Beijing and some other big city even to building energy efficiency 65%.

Our country's current heating energy consumption is very large, about 3 times that of developed countries, new heat radiator should cause height to take seriously. Now from the energy saving and environmental protection from the perspective of China's existing radiator properties, while people scientific selection.

1, from the material, good heat radiating speed, high thermal efficiency, relative energy saving. All kinds of material coefficient of thermal conductivity of high ranking : copper, aluminum alloy, aluminum, steel, cast iron, stainless steel, plastic. From the thermal efficiency, the best of times of copper, aluminum, steel or plastic, the worst.

2, from the production conditions, simple technology, mechanization, high degree of automation, energy consumption energy saving products. Cast iron radiator production process is complicated, the total energy consumption is high, steel radiator production process is simple, mechanization, high degree of automation, the low energy consumption, low cost.
