Heat exchangers and air conditioning units

Abstract

Provide a heat exchanger and air -conditioning device, which can inhibit the refrigerant bias even under the condition of circulating changes.There are multiple flat porous tubes (21B, 121B) at different heights of the backbone concentration collection pipe (23) of the outdoor heat exchanger (20).The circular structure is adopted in the first internal space (23A), which includes the first partition (51), the first -led entrance (41X), the first upper connecting path (51X), and the first connecting path (51Y).The first -class entrance is used to increase the refrigerant in the first space (51A).From the first rectification board (41), the first partition (51), the first shield (61), the separation of the first outflow (51A), the first cycle space (51B), the first -class space (61B), The first rising space (61A).The refrigerant pathway of the flat pipe (121B) connected to the first flow (61B) connection and the connected port (61X) connected to the first -rate space (61A) connection (61X) connected to the first -led space (61B) of the first flow (121B) is configured to be configuredDo not overlap each other.

Description

technical field [0001] The invention relates to a heat exchanger and an air conditioner. Background technique [0002] Conventionally, there is known a heat exchanger which has a plurality of flat tubes, fins joined to the plurality of flat tubes, header headers respectively connected to one end side and the other end side of the plurality of flat tubes, And the heat exchanger exchanges heat between the refrigerant flowing inside the flat tubes and the air flowing outside the flat tubes. [0003] For example, in the heat exchanger described in Patent Document 1 (Japanese Patent Application Laid-Open No. 2-219966), the following structure is adopted: both ends of a plurality of outflow pipes extending in the horizontal direction are respectively connected to collectors extending in the vertical direction. Tube manifold. [0004] In the heat exchanger described in this patent document 1, there is the following technical problem: in the inside of the header tubes extending in...

AI Technical Summary

Problems solved by technology

[0004] In the heat exchanger described in this patent document 1, there is the following technical problem: in the inside of the header tubes extending in the vertical direction, since the liquid-phase refrigerant with a large specific gravity gathers below and the gas-phase refrigerant with a small specific gravity gathers above, thus creating a bias current
