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

.

The series type air heat exchanger adopts advanced mechanical expansion pipe and circular arc corrugated aluminum plate structure. The mechanical expansion makes the copper tube contact with the aluminum rib closely, the circular arc corrugation can promote the fluid turbulent flow, destroy the air boundary layer, improve the heat transfer coefficient. Advanced structure, coupled with the reasonable design of water stroke, pipe length and film spacing, makes the heat exchanger has the advantages of good heat transfer performance, small air resistance, compact structure and light weight.

Widely used in air conditioning, cooling, dehumidification, heating and other projects, the most fresh air units and air processors ideal supporting products, it can also be used as a cooling or heating link with the air duct alone.
