Title:

HEAT EXCHANGER AND AIR CONDITIONING DEVICE

Document Type and Number:

WIPO Patent Application WO/2015/098859

Kind Code:

A1

Abstract:

Provided is a heat exchanger that can suppress uneven flow of coolant even when used under conditions wherein circulation volume changes. Also provided is an air conditioning device. A plurality of flat, multi-hole pipes (21b, 121b) are connected at different heights to a first inner space (23a) of a folding-back header collecting pipe (23) of an outdoor heat exchanger (20). The first inner space (23a) has a loop structure that includes: a first partitioning plate (51); a first inflow hole (41x) that is for causing coolant to rise into a first outflow space (51a); a first upper passageway (51x); and a first lower passageway (51y). The first outflow space (51a), a first loop space (51b), a first inflow space (61b), and a first upflow space (61a) are separated by a first rectifying plate (41), the first partitioning plate (51), and a first obstructing plate (61). A coolant path of the flat pipe (121b) that is connected to the first inflow space (61b) is positioned so as not to coincide with a lower connecting hole (61x) that connects the first inflow space (61b) and the first upflow space (61a).
