Document Type and Number:
WIPO Patent Application WO/2023/030416
Kind Code:
A1
Abstract:
A heat exchanger, comprising: a first heat exchange portion (10), the first heat exchange portion (10) comprising a plurality of first flat tubes (11) arranged at intervals, each first flat tube (11) comprising a first heat exchange tube section (111) and a second heat exchange tube section (112) connected to each other, the first heat exchange tube section (111) and the second heat exchange tube section (112) being arranged at a preset angle; a first collecting tube (20) and a second collecting tube (30), the first heat exchange tube sections (111) of the plurality of first flat tubes (11) being all connected to the first collecting tube (20), and the second heat exchange tube sections (112) of the plurality of first flat tubes (11) being connected to the second collecting tube (30); and a second heat exchange portion (40), disposed at the end of the first heat exchange portion (10), the first heat exchange portion (10) and the second heat exchange portion (40) defining an air duct. The heat exchanger can solve the technical problem in the prior art of poor heat exchange performance of an A-type heat exchanger.
