Air heat exchanger (also known as radiator) It is the main equipment in the heat exchange device for cooling or heating air with cold and hot medium. The air can be heated by high temperature water, steam or high temperature heat transfer oil, and the air can be cooled by brine or low temperature water. Therefore, it can be widely used in hot air heating and air conditioning in light industry, construction, machinery, textile, printing and dyeing, electronics, food, starch, medicine, metallurgy, coating and other industries Cooling, condensation, dehumidification, drying, etc. It is an ideal heat exchange equipment especially in the working environment with insufficient water source.

The heat transfer component of air heat exchanger is finned tube, and its base tube material can be carbon steel, copper, titanium material, stainless steel, etc. the fins are generally aluminum alloy, copper, carbon steel, stainless steel, etc. The classification of finned tube is as follows: winding L-type, bimetal rolling Dr type, inlaid G-type, welding type, etc. Generally, Dr type is more commonly used. After being closely combined by bimetal, the aluminum sheet is in close contact with the steel pipe, with good heat dissipation performance and reliable use. Its heat dissipation tube has the characteristics of small thermal resistance, high strength, low resistance, not easy to dust, strong anti-corrosion performance and high heat exchange efficiency.

The air heat exchanger is generally suitable for the working conditions where the gas side pressure is not high ± 20KPa (g) and the tube side pressure is less than or equal to 2.5MPa. The shell is generally made into square shape, with compact structure and large heat exchange area per unit volume. It has the advantages of good heat transfer performance, high anti-corrosion performance and no deformation under long-term cold and hot conditions.

On the basis of previous experience, Vickers has specially designed several air heat exchangers with high reliability and can eliminate temperature difference stress. Therefore, it has applied for several patents. It can be said that the air heat exchanger products of our company have many advantages, such as high heat transfer performance, good reliability and long service life.
