Problems solved by technology
That is, it is necessary to increase the surrounding space of the piping before and after the distributor, which leads to an increase in the size of the air conditioner (for example, a load-side unit such as an indoor unit) equipped with a heat exchanger.
[0005] In addition, depending on the installation angle of the dispenser, there is also a problem that the distribution performance varies

[0021] figure 1 It is a figure which shows an example of the refrigerant circuit structure of the air conditioner 100 which concerns on embodiment of this invention. The air conditioner 100 is used to cool or heat a space to be air-conditioned, such as a room, by performing a vapor compression refrigeration cycle operation.
[0022] like figure 1 As shown, the air conditioner 100 includes: a heat source unit 10 that supplies a heat source to a load side unit 20 ;
[0023] In addition, the air conditioner 100 includes a refrigerant circuit configured by connecting the compressor 1 , the flow switching device 2 , the first heat exchanger 3 , the decompression device 4 , and the second heat exchanger 5 through the refrigerant piping 15 .
[0024] The compressor 1 , the flow switching device 2 , the first heat exchanger 3 , and the decompression device 4 are mounted on the heat source unit 10 , and the second heat exchanger 5 is mounted on the load side unit 20 .

The present invention relates to a heat exchanger and an air conditioner. The heat exchanger is provided with plate-shaped fins having a longitudinal direction, a plurality of heat transfer tubes passing through the fins, and two of the plurality of heat transfer tubes for transferring refrigerant to two of the plurality of heat transfer tubes. A distributor for distributing heat pipes, the distributor includes: a linear inflow portion connected to one of the plurality of heat transfer tubes, a turn-back portion continuous to the inflow portion, and a linear inflow portion continuous to the turn-back portion and extending parallel to the inflow portion. The first outflow part, the straight second outflow part which is continuous with the folded part and branched from the first outflow part, and the connecting pipe which is continuous with the second outflow part and formed with a plurality of bending parts, connects the second outflow part through The connecting pipe is connected to a heat transfer tube that is not adjacent to the heat transfer tube connected to the first outflow portion.
Description
technical field [0001] The present invention relates to a heat exchanger including a distributor for distributing refrigerant, and an air conditioner provided with the heat exchanger. Background technique [0002] A heat exchanger used in an air conditioner having a refrigerant circuit functions as a condenser or an evaporator due to the flow of refrigerant. In such a heat exchanger, as a means of reducing the pressure loss of the refrigerant and improving heat exchange efficiency, a method of branching the refrigerant flow path into a plurality of paths is adopted. When branching the refrigerant flow path into a plurality of paths, a distributor is generally used on the refrigerant inlet side of the heat exchanger. For example, in Patent Document 1, it is proposed to use a distributor having a Y-shaped cross section in order to branch the refrigerant flow path from one to a plurality (six). Additionally, distributors are sometimes referred to as distribution lines or spli...
