Document Type and Number:
WIPO Patent Application WO/2020/230268
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a heat exchanger equipped with a plurality of heat exchanger tubes connected to each other at both ends in the tube axis direction, such that it is possible to suppress deformation, and a refrigeration cycle device. The heat exchanger and the refrigeration cycle device according to the present invention comprise: a plurality of components that are arranged in parallel in a first direction in spaced relation to each other; and a header that is connected to the plurality of components at the ends of the plurality of components in a second direction intersecting the first direction. The plurality of components are each equipped with a body portion that extends in the second direction and an extension portion that extends in a third direction, which intersects a plane parallel to the first direction and the second direction, from the end edge portion of the body portion in the third direction. The end edge portion is a portion of the end edge of the body portion which excludes the end of the body portion in the second direction. The header is formed with a plurality of insertion holes into which the end portions of the body portions of the plurality of components are inserted. The plurality of components are each equipped with a first component in which no refrigerant flows inside the body portion and a second component in which a refrigerant flows inside the body portion.
