The first main coil 132a, the first bracket panel pipe 133a on first diverter branch, finally come together in the general export pipe；It is a part of again
Through the second main coil 132b, the second bracket panel pipe 133b, the fourth officer coil pipe 133d on the second diverter branch, finally come together in described
General export pipe；Rest part refrigerant flows to institute through third main coil 132c, the third bracket panel pipe 133c on third diverter branch
General export pipe is stated, and is collected with the refrigerant of aforementioned first diverter branch and the second diverter branch.
Fig. 6 and Fig. 7 are please referred to, in the present embodiment, it is contemplated that the refrigerant of aforementioned each distribution pipeline is pooled to described
When general export pipe, the refrigerant exit temperature difference of each distribution pipeline should not be too large, otherwise the refrigerant mixing of different temperatures
Heat exchange, substantially reduces heat exchange efficiency.Therefore, in each distribution pipeline total tube side of main coil and bracket panel pipe with remaining any one point
Total tube side of main coil and bracket panel pipe should generally remain suitable in stream branch, to ensure the refrigerant outlet temperature of each distribution pipeline
Degree difference is smaller.
In the present embodiment, the fourth officer coil pipe 134 and third bracket panel pipe 133c are respectively positioned on the one-row heat exchanger 130
Topmost, the one-row heat exchanger 130 is in the fourth officer coil pipe 134, third bracket panel pipe 133c and the first bracket panel pipe 133a
Upper part position formed refrigerant cross cold-zone, air inlet air-flow from this cross cold-zone by when, the heat of acquisition is less, from
And the lower cold airflow of temperature is blown out in the upper end of the air outlet, which settles downwards to suppress the thermal current of lower section,
To reach more preferably warm sufficient effect.
In the present embodiment, in order to ensure forming overheated zone in the lower end of the one-row heat exchanger 130, so as to go out derived from described in
The blowout of air port lower end is thermal current, to reach warm sufficient effect, it is preferable that the height of the fins set is H0, the multiple master
The total height that coil pipe occupies the fins set is HAlways, HAlways∈[0.2H0, 0.4H0], for example, 0.25H0、0.30H0、0.35H0Deng.
Under heating mode, the lower end position of one-row heat exchanger 130 forms the overheated zone at least formed with refrigerant, and in the single heat exchange
The middle part of device 130 and its two-phase section for sequentially forming refrigerant above and cold-zone excessively so that by the sky of each section pipe group heat exchange
Gas obtains different heats, and the distribution of gradient from high in the end is presented in the temperature of outlet air air from top to bottom so that from it is lower to
On temperature gradually change, amplitude of variation is smaller, has both improved the inhomogeneities of heat exchange, improves heat exchange efficiency, and improve
Comfort.
Fig. 6 and Fig. 7 are please referred to, in the present embodiment, the height that the n main coil 132 occupies the fin can be with base
This is identical, can also differ.Here, in order to improve the leaving air temp of air outlet lower end, to reach warm sufficient effect, it is preferable that
In the n main coil 132, the main coil 132 for being located at bottom is that the first main coil 132a, the first main coil 132a occupies institute
The height for stating fins set is H1, it is located at any one master other than the main coil of the top above the first main coil 132a

The multiple heat exchange fin 131 is intervally arranged successively around the periphery of tubular wine wheel 120.If between the multiple heat exchange fin 131
Spacing it is excessive, easily cause air inlet air-flow and heat exchange fin 131 it is insufficient contact, heat transfer effect is poor；If the multiple heat exchange
Spacing between fin 131 is too small, then the multiple heat exchange fin 131 is more intensive and increase windage, and air inlet air-flow is difficult to
By one-row heat exchanger 130, air output is greatly reduced.Therefore limit herein, between two heat exchange fins 131 of arbitrary neighborhood
Spacing is 0.6mm~2.0mm, for example, can be specifically 0.8mm, 1.0mm, 1.2mm, 1.5mm or 1.8mm etc..Here, arbitrary
Spacing between the two adjacent heat exchange fins 131 is preferably 1.0mm~1.5mm, with this ensure each heat exchange fin 131 with
While air inlet air-flow comes into full contact with heat exchange, air inlet air-flow can move smoothly through one-row heat exchanger 130.
Further, to ensure that the one-row heat exchanger 100 has larger heat exchange area while, and ensure that air-flow can
Smooth to pass through, therefore preferably, the width of each heat exchange fin is 10mm~25mm, for example, 12mm, 14mm, 16mm, 18mm,
20mm, 22mm or 24mm etc..Particularly, the corresponding central angle of sector region shared by one-row heat exchanger 130 be 120 °~
Spacing between 130 ° and two heat exchange fins 131 of arbitrary neighborhood is 0.8mm~1.5mm, each heat exchange fin
When 131 width is 18mm~20mm, one-row heat exchanger 130 reaches best heat exchange efficiency, better than conventional double heat exchange
Device.Particularly, the corresponding central angle of sector region shared by one-row heat exchanger 130 is the two of 120 °~130 ° and arbitrary neighborhood
Spacing between the heat exchange fin 131 is 0.8mm~1.5mm, when the width of each heat exchange fin is 18mm~20mm,
One-row heat exchanger 130 reaches best heat exchange efficiency.
