The technical solution of the utility model, by the way that the caliber D design of the refrigerant pipe 20 of fin-tube type heat exchanger 100 exists
2.5mm≤D≤4mm range, while requiring the tube spacing PtMeet 10mm≤Pt≤ 13mm, the width P of the fin 10rSymbol
Close 9mm≤Pr≤ 13.9mm makes the fin-tube type heat exchanger 100 when using small diameter tube refrigerant pipe 20, by reasonable with this
Control tube spacing PtWith select arrow gauge (the lesser fin of width), to improve the synthesis heat exchange property of the fin-tube type heat exchanger 100,
Make it have preferable heat exchange efficiency.Further, since the width of refrigerant pipe 20 caliber and fin 10 of the fin-tube type heat exchanger 100
Degree is smaller, to not only can reduce cost, can also reduce the overall volume of the fin-tube type heat exchanger 100, reduce and occupy
Space, and then air-conditioner outdoor unit may make to minimize.
Based on the above embodiment, for the slot opening form of the fin 10 then there are many, such as: the fin 10 is chosen as
Corrugated fin perhaps bridge chip-type fin or louvered fin.But for the width P of the fin 10rMeet 9mm
≤PrFor≤13.9mm, which belongs to arrow gauge.The slot opening form of arrow gauge has the fin-tube type heat exchanger 100 different
It influences.Here, being carried out to study influence of the type of arrow gauge to the synthesis heat exchange property of the fin-tube type heat exchanger 100
Following experiment, it is as follows that experiment obtains performance test data:
The synthesis heat exchange property enhancing rate of 2. different type arrow gauge of table
| Fin type | Compared to the enhancing rate of sheet type fin |
| Sheet type fin | 0 |
| Corrugated fin | 2.5 |
| Bridge chip-type fin | 3.6 |
| Louvered fin | 3.2 |
It is drawn to obtain the cylindricality of the synthesis heat exchange property enhancing rate of the arrow gauge of different slot opening forms according to the data of above-mentioned table 2
Scheme (such as Fig. 6).Referring to Fig. 6, being compared by the experimental result as it can be seen that the fin of the fin-tube type heat exchanger 100 is using bridge piece formula
When fin, synthesis heat exchange property is opposite to be able to ascend 3.6%, is higher than other types fin.Therefore, in the present embodiment, institute
The fin 10 for stating fin-tube type heat exchanger 100 is chosen as bridge chip-type fin.
Based on the above embodiment, the fin of the fin-tube type heat exchanger 100 is bridge chip-type fin.The bridge chip-type fin
Surface is provided with multiple bridge piece units (not shown) arranged along its length.The bridge piece unit includes multiple along the bridge
The bridge piece that the width direction of chip-type fin is intervally arranged.As for the quantity of the bridge piece, limited there is no specific.For example, described
The quantity of bridge piece is chosen as 2~6.But, it is contemplated that the quantity of bridge piece exchanges heat to the comprehensive of the fin-tube type heat exchanger 100
Performance also has an impact.Therefore, experimental study has also been carried out to the quantity of bridge piece, has measured that the experimental data are shown in the following table 3:
The synthesis heat exchange property change rate of the different bridge piece quantity of table 3.
| Ripple quantity | Comprehensive heat exchange property change rate |
| 2 | 2.4% |
| 3 | 3.8% |
| 4 | 4.8% |
| 5 | 3.8% |
| 6 | 2.6% |
The change curve (such as Fig. 7) that fitting obtains comprehensive heat exchange property change rate is drawn according to above-mentioned table 3.
As seen from Figure 7, the change rate of the synthesis heat exchange property of the fin-tube type heat exchanger 100, on the fin 10
The increase of bridge piece quantity first gradually rises, and then arrives reach to peak value (bridge piece quantity is about 4 at this time), then gradually decrease.Thus
As it can be seen that it is not The more the better for being formed by bridge piece quantity on the fin 10, but need to be maintained at a preferable range
It is interior.Theoretically, the bridge piece quantity of the fin 10 is chosen as 2~6, such as 2,3,4,5,6.
Referring to Fig. 5, in the present embodiment, theoretically, the bridge piece quantity of the fin 10 is chosen as 2~6, such as
2,3,4,5,6.But being 2 or 6 in view of bridge piece quantity is that its heat exchange property change rate is lower.Therefore,
In a further preferred embodiment, choosing comprehensive heat exchange property change rate is 3.8%~4.8% for more excellent section, and correspondence can determine
The bridge piece quantity optimized scope of the fin 10 is 3~5 out, such as, but not limited to 3,4,5.Optimal bridge piece number
Amount is chosen as 4.
Based on above-mentioned any one embodiment, it is contemplated that when between the two adjacent fins 10 of the fin-tube type heat exchanger 100
Spacing is smaller, the droplet when the height of condensation droplet is more than to cool down the spacing between two adjacent fins 10, between fin 10
It will connect, form firm " water bridge ".Obviously, " water bridge " meeting occupied space, increases windage, is unfavorable for air stream and moves
Heat.Therefore, it is the generation of reduction " water bridge ", optionally, hydrophilic layer is set on the surface of the fin 10.The hydrophilic layer can be with
It is hydrophilic aluminum foil coating.The hydrophilic layer has stronger affinity to water, the hydrophily of fin 10 is improved, so that condensed water exists
It is spread on fin 10 very fast, it is not easy to be formed " water bridge ", and then reduce windage, be convenient for air fluid interchange.
In the present embodiment, the refrigerant pipe 20 is chosen as inner screw thread copper pipe or smooth copper.Wherein, the refrigerant
When pipe 20 is inner screw thread copper pipe, wherein internal screw thread is conducive to enhancing heat exchange, so can help to improve heat exchange efficiency.Therefore, institute
Stating refrigerant pipe 20 is preferably inner screw thread copper pipe
The utility model also provides a kind of air conditioner, and the air conditioner includes air conditioner indoor unit and air-conditioner outdoor unit, described
Air-conditioner outdoor unit is connected with the air conditioner indoor unit by refrigerant pipe.The specific structure of the air-conditioner outdoor unit is referring to above-mentioned implementation
Example, since this air conditioner uses whole technical solutions of above-mentioned all embodiments, the same skill with above-described embodiment
All beneficial effects brought by art scheme, this is no longer going to repeat them.
The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model,
It is all under the inventive concept of the utility model, equivalent structure made based on the specification and figures of the utility model becomes
It changes, or directly/be used in other related technical areas indirectly and be included in the scope of patent protection of the utility model.
