HEAT EXCHANGER, METHOD OF PRODUCING THE HEAT EXCHANGER

摘要

A heat exchanger includes a heat transfer tube functioning as a flow path for refrigerant and also includes metal fins. The metal fins transmit heat of the heat transfer tube to air and have pores that are open inward from the surfaces of the metal fins and absorb and release moisture in the air when relative pressure is in the range of 0.1 - 0.9. The pores have a diameter in the range of 1 - 20 nm and a depth in the range of 1 - 100 µm.
