The utility model relates to an air heat exchanger, which is a heat exchanger which is used as a medium for cooling or heating forced flowing air, such as water, glycol solution, steam, heat conduction oil, etc.. Widely used in light industry, construction, chemical industry, machinery, textile, printing and dyeing, electronics, food, starch, medicine, metallurgy, painting and other industries in the hot air heating, drying, cooling, dehumidification and other projects. Different types of heat exchangers are selected according to different working conditions. Air heat exchanger: heat exchanger tube type classification: around the chip, rolled plate, string, chip type; base material: seamless steel tube, purple / yellow steel pipe fin material: steel, aluminum sheet

Rolling type air heat exchanger adopts advanced technology of steel aluminum composite, with combination of low thermal resistance, heat transfer performance, small flow loss, heat transfer performance, small flow loss, good corrosion resistance, not easy to deformation in hot and cold conditions under the long-term characteristics, long service life and so on.

Material: carbon steel aluminum sheet, stainless steel sheet, aluminum sheet.
