Heat exchanger tube for an air-conditioning apparatus |
摘要 |
A groove configuration, formed on an inside wall of a heat exchanger tube, has a cross-sectional area varying in the longitudinal direction of the heat exchanger tube. An increased rate of the cross-sectional area is differentiated from a decreased rate of the cross-sectional area by changing the height or top width of a protruding portion, or the depth or bottom width of a recessed portion.
