Embodiment Construction

[0048] (1) Overall structure of the air conditioner 1

[0049] figure 1 It is a circuit diagram showing the outline of the configuration of the air conditioner 1 according to one embodiment of the present invention.

[0050] The air conditioner 1 is a device for cooling and heating a building in which an air-conditioning indoor unit 3 is installed by performing a vapor compression refrigeration cycle operation. The air conditioner outdoor unit 2 and the air conditioner indoor unit 3 as the utilization side unit are connected together.

[0051] The refrigerant circuit formed by connecting the air-conditioning outdoor unit 2, the air-conditioning indoor unit 3, and the refrigerant communication pipes 6 and 7 is to connect the compressor 91, the four-way switching valve 92, the outdoor heat exchanger 20, and the expansion valve through refrigerant piping. Valve 33, indoor heat exchanger 4, storage tank 93, etc. Refrigerant is sealed in this refrigerant circuit, and a refrigera...

Abstract

Provided is a heat exchanger that can produce an upflow of coolant even when structured such that coolant is not directly supplied to a lower part of a space that generates a coolant upflow inside a header collecting pipe. Also provided is an air conditioning device. A plurality of flat, multi-hole pipes (21b) are connected at different heights to a first inner space (23a) of a folding-back header collecting pipe (23) of an outside 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), and a first lower passageway (51y) that causes coolant from the first upper passageway (51x) to descend through a first loop space (51b) and guides the coolant back to the first outflow space (51a). One end of the flat, multi-hole pipes (21b) is connected to either the first outflow space (51a) or the first loop space (51b). Connective piping (24) is connected to a space that is below the first loop space (51b) across a first rectifying plate (41).

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...
