Title:
HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2017/135442
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a multirow microchannel heat exchanger which prevents decreases in heat exchange performance. In this outdoor heat exchanger (25), a coolant entry (253a) and a coolant exit (257a) can be arranged diagonally opposite of each other in an expanded configuration prior to formation of a first flexed portion (250b), so the coolant entry (253a) and the coolant exit (257a) can be arranged in different rows. Further, since the coolant entry (253a), into which a high-temperature coolant flows, is arranged downstream in the airflow direction, air is prevented from overheating upstream. In other words, heat exchange between the coolant and the "air that has been overheated upstream" is avoided, improving heat exchange performance.
