The application of micro-channel heat exchanger meets the growth requirement of the energy-saving and cost-reducing and environmental protection of country, is badly in need of being applied to family expenses/business air conditioner.But,, need be optimized design again to the original elementary structure parameter of micro-channel heat exchanger fin in order to improve the complete machine cost performance because the operating condition (as wind speed, condensation temperature, heat flow density) of family expenses/business air conditioner and cold-producing medium etc. are different from air conditioning for automobiles.
Therefore, the utility model provides a kind of fin and comprises the micro-channel heat exchanger of the family expenses/business air conditioner of this fin, its micro-channel heat exchanger that can overcome prior art can only be applied to the limitation of air conditioning for automobiles, make its range of application wider, improve the heat exchange efficiency and the combination property of micro-channel heat exchanger.
[utility model content]
The micro-channel heat exchanger that the purpose of this utility model is to provide a kind of fin and comprises the family expenses/business air conditioner of this fin, it improves the heat exchange efficiency and the combination property of micro-channel heat exchanger by the micro-channel heat exchanger air side fins is carried out hot optimal design.
For realizing the utility model purpose, provide following technical scheme:
A kind of fin, it is applied to be channel heat exchanger, this fin extends distribution with waveform, on the corrugated sidewall of this fin, be provided with two groups of shutters, this every group of shutter forms louver angle along perk of fin both sides and sidewall surfaces, shutter on the adjacent wall overlaps after folding along crest or trough, and the louver angle of this shutter is 20 °～34 °.
Preferably, the adjacent crest and the distance between the trough of this fin are a pitch of fins, and this pitch of fins is 1mm～1.6mm.
Preferably, this fin height is 5mm～10mm, and windowing of this shutter highly is 80%～90% of this fin height.
This every group of shutter comprises a plurality of silvers, and preferably, the width of this silver is 1～1.2mm.
The utility model also provides a kind of micro-channel heat exchanger of family expenses/business air conditioner, and it comprises a plurality of flat tubes, and be arranged between adjacent two flat tubes as above each described fin.Preferably, the width of this flat tube is 10mm～26mm, and the height of this flat tube is 1mm～1.8mm.
The contrast prior art, the present invention has the following advantages:
Redesigned micro-channel heat exchanger fin shutter louver angle, windowed highly and a pitch of fins at family expenses/business air conditioner operating condition, adjust structural parameters such as flat tube width and fin height simultaneously, formed temperature field, Flow Field Distribution more become reasonable when making air skim over louvered fin, and under the constant situation of integrated cost, improve the coefficient of heat transfer and the unit are exchange capability of heat of fin, effectively improve the combination property of fin.

[specific embodiment]
As shown in Figures 1 and 2, the micro-channel heat exchanger of the utility model family expenses/business air conditioner, it comprises a plurality of flat tubes 1, and be arranged at fin 2 between adjacent two flat tubes 1, this fin 2 extends distribution with waveform, be provided with two groups of shutters 21,22 on the corrugated sidewall of this fin, this every group of shutter 21 (22) forms louver angle θ along fin 2 both sides perks and sidewall surfaces, and the shutter 21 (22) on the adjacent wall overlaps after folding along crest or trough.
As shown in Figure 3.Preferably, this every group of shutter 21 (22) includes a plurality of silvers 23 that are provided with of arranging in the same way, and the number of this silver is 10～12.
Embodiment below in conjunction with different specifically describes the present invention.
Embodiment one: shutter entrance region length S
1=1.25mm, shutter turn to section length S
2=1.5mm, shutter outlet area length S
3=1.25mm, fin height F
h=8mm, window the height L
1=6.5mm, shutter louver angle θ=20 °, shutter silver width L
p=1mm, flat tube width T
d=16mm, flat tube height T
Th=1.8mm, pitch of fins F
p=1.3mm, fin thickness t
f=0.1mm.
The micro-channel heat exchanger fin of embodiment one by louver angle θ, window the height L
