The aluminum radiator is a new type of air heater improved on the basis of steel radiator. The heat exchange element of the product is made of steel tube -aluminum "L" type finned tube, and the working temperature can reach 230℃. It has the advantages of tight contact, no wrinkle, no dust accumulation, good vibration resistance, and can protect the pipe from air erosion. Compared with the steel radiator, the heat dissipation area is increased by 10-20%, the weight is reduced by about 30%, and the heat can be increased by 10-20% under the same working conditions. It is suitable for steam and hot water systems. It can be widely used in air heating, material drying, and air conditioning systems. The heat medium of the radiator is steam or hot water, the working pressure of steam is 2.6MPa, and the temperature of hot water is 70-130℃.
