Air heat exchanger

Air heat exchangerIn

the air conditioning engineering, the finned tube heat exchanger, which is widely used in the process of air heating and cooling, is in the form of coil.

The heat transfer tube bundle is made of copper tubes with smaller diameter and aluminum fins, arranged in 2 to 8 rows. The hot and cold water flow in the tube in a serpentine reciprocating way. The air passes through the fins outside the tube and is heated or cooled at the same time. The fins are in the form of integral fins, and the fin types are flat, wrinkled (among them, corrugated plate is the most widely used) and slotted (such as slat type, louver type, etc.).
