HEAT EXCHANGER AND AIR CONDITIONER HAVING THE SAME AND MANUFACTURING PROCESS OF THE SAME

摘要

A heat exchanger is provided. The heat exchanger includes a plurality of aluminum tubes formed of aluminum, each of the aluminum tubes including a plurality of grooves that are formed on an inner circumferential surface of each of the aluminum tubes and that extend along a longitudinal direction of the aluminum tubes; and a plurality of heat transfer fins coupled to the aluminum tubes. The heat exchanger may contribute to the reduction of the manufacturing cost, may provide high heat transfer performance and may prevent a coolant leak.
