Title:
HEAT EXCHANGE TUBE AND HEAT EXCHANGER HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2021/115461
Kind Code:
A1
Abstract:
A heat exchange tube (1) and a heat exchanger having same. A plurality of circulation channels are provided inside the heat exchange tube (1). The plurality of circulation channels comprise a first channel (201) and a second channel (301). The heat exchange tube (1) comprises a first section (100), a second section (200) and a third section (300). A plurality of the first channels (201) constitute a first channel layer along a second direction (B), and a plurality of the second channels (301) constitute a second channel layer along the second direction (B), the number of the second channel layers being greater than that of the first channel layers. The heat exchange tube (1) is divided, along the second direction (B), into a first region and a second region which are equal in width, the cross section of the heat exchange tube (1) takes its shape with the intersection of the width and the thickness of the heat exchange tube (1) and comprises circulation sections, and the total area of the circulation sections in the first region is greater than that in the second region. The heat exchange efficiency of the heat exchanger using the heat exchange tube (1) is improved, and the welding quality of the heat exchanger is further improved.
