(3) feature of outdoor heat converter
The outdoor heat converter 400 of present embodiment has fins set 410 and flat tube group 420.Flat tube group 420 includes
1st flat tube 421, the 2nd flat tube 422, the 3rd flat tube 423 and the 4th flat tube 424.By bending the 1st flat tube the 421, the 2nd
The stream of flat tube 422, the 3rd flat tube 423 and the 4th flat tube 424 and formation cold-producing medium, therefore can not possess cold-producing medium collection
Pipe.Therefore, it is possible to cause heat exchanger miniaturization.Further, since can not possess refrigernant collector, therefore, it is possible to improve the 1st
The degree of freedom of the design of flat tube 421, the 2nd flat tube 422, the 3rd flat tube 423 and the 4th flat tube 424.
In the outdoor heat converter 400 of present embodiment, the 1st toward road portion 421b1Road portion 421d is returned with the 1st1It is past positioned at the 2nd
Road portion 422b1Road portion 422d is returned with the 2nd1Between.2nd toward road portion 422b1Road portion 422d is returned with the 2nd1Positioned at the 3rd toward road portion 423b1
Road portion 423d is returned with the 3rd1Between.3rd toward road portion 423b1Road portion 423d is returned with the 3rd1Positioned at the 4th toward road portion 424b1Road is returned with the 4th
Portion 424d1Between.3rd toward road portion 423b1Across the 2nd toward road portion 422b1And the 1st is located at toward road portion 421b1Opposition side.3rd returns
Road portion 423d1Road portion 422d is returned across the 2nd1And be located at the 1st and return road portion 421d1Opposition side.Accordingly, the 1st flat tube the 421, the 2nd
Flat tube 422, the 3rd flat tube 423 and the 4th flat tube 424 do not intersect each other, can keep abreast of state.
In the outdoor heat converter 400 of present embodiment, the 1st flat tube 421 with 3 the 1st toward road portion 421b, 3 the 1st
Return portion 421c and 3 the 1st return road portion 421d.2nd flat tube 422 is with 3 the 2nd toward road portion 422b, 3 the 2nd return portions
Return road portion 422d for 422c and 3 the 2nd.3rd flat tube 423 is with 3 the 3rd toward road portion 423b, 3 the 3rd return portions 423c and 3
3rd returns road portion 423d.4th flat tube 424 returns road portion toward road portion 424b, 3 the 4th return portions 424c and 3 the 4th with 3 the 4th
424d.As described above, the 1st flat tube 421, the 2nd flat tube 422, the 3rd flat tube 423 and the 4th flat tube 424 are keeping abreast of
Wriggle while state.Therefore, the 1st flat tube 421, the 2nd flat tube 422, the 3rd flat tube 423 and the 4th flat tube 424 are compared
For the independently sinuous situation in region different from each other, them can be reduced each other in Y direction, i.e. vertical
Difference.Thus, can expect to suppress the mass flow discrepancy of cold-producing medium.
＜ variations ＞
Variation to being applied in embodiment of the present utility model is illustrated below.In addition, following is each
Variation can be applied in combination with other variations in the range of contradiction not produced.
(1) variation A
Fig. 4 is the plane graph of the outdoor heat converter 400a of another that is denoted as outdoor heat converter 400.1st is flat
Said in the structure of flat pipe 421, the 2nd flat tube 422, the 3rd flat tube 423 and the 4th flat tube 424 such as (2-2-1) to (2-2-4)
Bright content.1st flat tube 421, the 2nd flat tube 422, the 3rd flat tube 423 and the 4th flat tube 424 are with Uncrossed side each other
Formula is wriggled, and this is common in the outdoor heat converter 400 of the outdoor heat converter 400a and Fig. 3 of Fig. 4.1st flat tube
421st, outdoor heat converter 400a of the position relationship of the 2nd flat tube 422, the 3rd flat tube 423 and the 4th flat tube 424 in Fig. 4
It is different with the outdoor heat converter 400 of Fig. 3.
In the outdoor heat converter 400a of Fig. 4, replace the 1st connecting portion 430 and the 2nd connecting portion 440 and be configured with collector
445.Collector 445 includes the hydraulic fluid side header portion 445a for being connected to liquid refrigerant pipe arrangement 202 and is connected to gas refrigerant
The gas side header portion 445b of pipe arrangement 201.The space in space and gas side header portion 445b in the header portion 445a of hydraulic fluid side
It is isolated or is separated.
In outdoor heat converter 400a, the 1st one end 421a, the 2nd one end 422a, the 3rd one end 423a and the 4th one end
Portion 424a is connected to hydraulic fluid side header portion 445a.Additionally, the 1st the other end 421f, the 2nd the other end 422f, the 3rd another

Integrally, but connected via the 3rd space S P3 by two pipe arrangements being split out and constituted.
4th space S P4 is connected with the gas side gateway for being connected with gas refrigerant pipe arrangement 201.In the formation of collector 450
On the part of the 4th space S P4, be connected with the 1st the other end 421f ', the 2nd the other end 422f ', the 3rd the other end 423f ' and
4th the other end 424f ', the 1st space S P1 and the 1st the other end 421f ', the 2nd the other end 422f ', the 3rd the other end
423f ' interior with the 4th the other end 424f ' refrigerant flow path is connected.Thus, in cooling operation, gas refrigerant passes through gas
Side gateway and from gas refrigerant pipe arrangement 201 flow into the 4th space S P4, the cold-producing medium in the 4th space S P4 is to the 1st other end
Portion 421f ', the 2nd the other end 422f ', the 3rd the other end 423f ' and the 4th the other end 424f ' flow out respectively.Additionally, in system
During heat run, gas refrigerant is from the 1st the other end 421f ', the 2nd the other end 422f ', the 3rd the other end 423f ' and the 4th
The other end 424f ' is flowed out to the 4th space S P4 respectively, and the cold-producing medium in the 4th space S P4 is by gas side gateway to gas
Cryogen pipe arrangement 201 flows out.
The other structures of outdoor heat converter 400b are roughly the same with outdoor heat converter 400.By outdoor heat converter
400b, can also expect to obtain the action effect roughly the same with outdoor heat converter 400.Wherein, in outdoor heat converter 400b,
Due to collector 450, thus compared with outdoor heat converter 400, can correspondingly be subject on the basis of densification is realized
Restriction.However, compare 1 is equipped with for the situation of collector, can expect the densification that outdoor heat converter 400b brings.
As described above, this utility model is illustrated using embodiment, but technical scope of the present utility model
The scope being not limited to described in above-mentioned embodiment.Those skilled in the art know and can apply various changes to above-mentioned embodiment
More or improve.Can be clear and definite according to the scope of claims, it is this be applied in change or improved mode should also be contained in
In technical scope of the present utility model.
