Document Type and Number:
WIPO Patent Application WO/2017/068723
Kind Code:
A1
Abstract:
To provide a heat exchanger and refrigeration cycle apparatus able to further improve heat exchange performance. The heat exchanger is provided with plate fins, as well as a first flattened tube and a second flattened tube. The major axis of the first flattened tube and the major axis of the second flattened tube are parallel with each other within a plane parallel to the plate fins. A slit extending parallel to the major axis of the first flattened tube and the major axis of the second flattened tube is formed in the plate-fin region between the first flattened tube and the second flattened tube. The length of the slit is shorter than the major-axis length of the first flattened tube and the major-axis length of the second flattened tube. The entire slit is provided between a straight line linking together one major-axis-direction end of each the first flattened tube and the second flattened tube along the plate fins and a straight line linking together the other major-axis-direction end of the first flattened tube and the second flattened tube along the plate fins.
