HEAT EXCHANGER

摘要

PURPOSE: A heat exchanger is provided to smoothly heat-exchange between air and heat exchange fins and to improve heat exchange rate by preventing generation of scale on the heat exchange fins. CONSTITUTION: A heat exchanger comprises a refrigerant pipe and heat exchange fins(30). Refrigerant flows through the refrigerant pipe. The heat exchange fins are coupled to the outer circumference of the refrigerant pipe. The heat exchange fin comprises a plate(40), an uneven part, slits(50), and a louver. The uneven part is projected from the plate. The slits are arranged in both sides of the uneven part and guides air to the uneven part. A louver is formed in the uneven part to heat-exchange with the air passed through the slits.
