Document Type and Number:

WIPO Patent Application WO/2018/181338

Kind Code:

A1

Abstract:

Provided are a heat exchanger and an air-conditioning device with which a greater number of flat tubes can be integrated in the lengthwise direction of a header or the header can be made more compact in the lengthwise direction. The heat exchanger is equipped with: a header (90); multiple flat perforated tubes (63) arranged side by side along the lengthwise direction of the header (90) and connected to the header (90); a partition plate (95) for circulation that partitions the interior space of the header (90) into a space for rising (98A) on the side on which the multiple flat perforated tubes (63) are connected and a space for descending (98B) on the opposite side from the space for rising (98A); and a nozzle-equipped, partially inclined partition member (70) for partitioning the interior space of the header (90) into an upper section and a lower section in the lengthwise direction of the header (90). The partition plate (95) for circulation has a shared opening (95U) that includes an upper insertion opening portion (95s) into which the nozzle-equipped, partially inclined partition member (70) is inserted and a connection opening (95c) which enables movement of refrigerant between a space on the flat perforated tube (63) side and a space on the opposite side of that space.
