HEAT EXCHANGER AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2012/098917
Kind Code:
A1
Abstract:
An upper-side heat exchange region (51) is divided into a plurality of principal heat exchange sections (51a-51c), and a lower-side heat exchange region (52) is divided into a plurality of auxiliary heat exchange sections (52a-52c). A first header/collector tube (60) is partitioned into an upper-side space (61) corresponding to the upper-side heat exchange region (51) and a lower-side space (62) corresponding to the lower-side heat exchange region (52). The lower-side space (62) is partitioned into a plurality of connection spaces (62a-62c) corresponding to each of the auxiliary heat exchange sections (52a-52c). The second header-collector tube (70) is partitioned into: a connection space (71c) jointly corresponding to both the lowest of the principal heat exchange sections (51a) in the upper-side heat exchange region (51) and the highest of the auxiliary heat exchange sections (52c) in the lower-side heat exchange region (52); and connection spaces (71a, 71b, 71d, 71e) respectively corresponding to the remaining principal heat exchange sections (51b, 51c) and auxiliary heat exchange sections (52a, 52b). A connecting tube (72) connects the connection space (71a) and the connection space (71d), while a connecting tube (73) connects the connection space (71b) and the connection space (71e).
