Further, the flat tube is with a thickness of 2.2-2.55mm, and flat tube 0.18~0.25mm of sidewall thickness, flat tube width is 12
~16mm.
Further, 32 °~38 ° of the fin louver angle, wave height 4.5-5.5mm.
Further, the flat tube with a thickness of 2.35mm, flat tube wall thickness 0.18mm, flat tube width 14mm, the fin is opened
38 ° of window angle, wave height 5mm.
Further, the flat tube cross section structure has above, below, and the semicircle of above and below two sides is arranged in, described
Semicircle and above and below connection type are non-tangential manner.
Further, the fin and flat tube use soldering connection.
Further, the flat tube is that aluminium is made using 3.
Compared with prior art, the invention has the following beneficial effects:
1) flat tube material of the present invention is that be changed to 3 be aluminium to aluminium from 1, is conducive to loss of weight and improves flat tube unit area heat-energy transducer
Power.
2) present invention increases flat tube thickness to 2.35mm, and flat tube wall thickness is reduced to 0.18mm, to increase flat tube endoporus area,
Guarantee single flat tube refrigerant passage area, while reducing fin wave height to 5mm and being protected with increasing on entire windward side flat tube quantity
It demonstrate,proves entire core and flows to area.
3) present invention adds the structure of two intersection semicircles using two planes to improve the practical contact area with fin of flat tube.
4) present invention increases fin louver angle, increases windowing number to improve the heat exchange of air side and fin.By
It calculates or verifies, 38 ° of fin louver angle, open a window number 7x4.
5) present invention is by improving soldering welded rate to improve the exchange capability of heat of entire core.

Specific embodiment
Referring to Fig. 1 to Fig. 6, lightweight high-performance parallel flow evaporators core includes flat tube in a preferred embodiment
And the fin at flat tube is set, the core thickness is X, 28mm≤X < 34mm；The flat tube is flat with a thickness of 2.3-2.4mm
Thickness of pipe wall (sidewall thickness) 0.18~0.25mm, flat tube width be 14~16mm, 32 °~38 ° of the fin louver angle, wave height
(height) 4.5-5.5mm.Flat tube described in preferred embodiment with a thickness of 2.35mm, flat tube thickness 0.18mm, the fin
Wave height is 5mm.Increase flat tube thickness to 2.35mm, reduces flat tube wall thickness and increase flat tube endoporus area to 0.18mm, guarantee single
One flat tube refrigerant passage area, while it is entire to guarantee to increase flat tube quantity on entire windward side to 5mm to reduce fin wave height
Core flows to area.
The flat tube cross section structure has above, below, and the semicircle of above and below two sides is arranged in, the semicircle with
