Abstract
A heat exchanger used for a refrigerating cycle has a plurality of grooves formed in the inner surface of a pipe thereof in the flowing direction of a refrigerant. At least two types of grooves which differ in width are used. The pipe also has fins which are coated with a hydrophilic paint that is black in color. This design enables the heat exchanger to provide improved performance.
