Meet: Pt ∈ [24.45mm, 25.95mm], corresponding Pl should meet: Pl ∈ [24.54mm, 27.08mm].
The technical solution of the utility model introduces a new type heat exchanger 1, and the refrigerant pipe 12 of the new type heat exchanger 1 is using single
Setting, and when the caliber of refrigerant pipe 12 belongs in 8.8mm~9.9mm, it is maintained at the interval Pt of adjacent refrigerant pipe 12
Within the scope of 22.6mm~27.55mm, the width Pl of fin 11 is maintained within the scope of 22.0mm~28.86mm, can make single change
Hot device reaches the heat exchange property of dual-row heat exchanger, it will be apparent that, which has used the smaller fin 11 of area, less
Refrigerant pipe 12, and heat exchange property same as dual-row heat exchanger can be reached, therefore, improve the energy of heat exchanger significantly
Effect.
Further, the interval of any two adjacent refrigerant pipes 12 is consistent.It is appreciated that being arranged such, on the one hand, can reduce
The technology difficulty in refrigerant hole is opened up on fin 11, on the other hand then improving the whole production efficiency of new type heat exchanger 1 also has
Conducive to guarantee air-flow after heat exchanger, the uniformity of outlet air.
Further, the equivalent width of multiple fins 11.It is appreciated that being arranged such, on the one hand, be conducive to improve novel
On the other hand the production efficiency of heat exchanger 1 is also beneficial to guarantee air-flow after heat exchanger, the uniformity of outlet air.The present embodiment
In, the width of fin 11 is 26mm, can according to the relational expression of the heat exchange property B of Fig. 4 or heat exchanger and the width Pl of fin 11
Know, when the width of fin 11 is 26, the heat exchange property B of heat exchanger reaches peak value.
Further, referring to figure 5 and figure 6, multiple fins 11 are in the arc arrangement towards inlet side projection, i.e. new type heat exchanger
The 1 whole arc in towards inlet side projection is arranged, in this way, being spaced in by windward side to leeward side between adjacent fins 11
It is gradually become smaller on direction, forms wind-guiding effect, preferably guidance air-flow passes through new type heat exchanger 1.
Further, referring to Fig. 6, the surface of each 11 windward side of fin is convexly equipped with heat transfer structure 111.It is appreciated that phase
The interval of adjacent 11 windward side of fin is larger, and air-flow is easy to pass through, and using the heat transfer structure 111, is conducive to increase changing for windward side
Heat area then enhances the heat transfer effect of windward side.In the present embodiment, which is along the wind-guiding direction of fin 11
The multiple heat transfer windows opened up are spaced, multiple heat transfer windows are divided on the side that the two of fin 11 is away from each other；Certainly, in other implementations
In example, which can also be heat transfer block, the heat transfer item etc. of projection, and the design is without being limited thereto.
Further, referring to Fig. 6, the surface of each 11 leeward side of fin is arranged in plain film shape.It is appreciated that adjacent fins
The interval of 11 leeward sides is smaller, using flat sheets, on the one hand, and be conducive to passing through for air-flow, it is avoided to cause to hinder to air-flow,
On the other hand, without additionally carrying out other designs to fin 11, the processing cost of new type heat exchanger 1 is advantageously reduced.It needs
Bright, the design is without being limited thereto, and in other embodiments, each fin 11 can also be equipped with wind-guiding wave by the surface of leeward side
Line.
The utility model also proposes a kind of air conditioner, which includes air-conditioner outdoor unit and air conditioner indoor unit, the air-conditioning
The specific structure of indoor unit is referring to above-described embodiment, since this air conditioner uses whole technical sides of above-mentioned all embodiments
Case, therefore at least all beneficial effects brought by the technical solution with above-described embodiment, 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,
Under all utility models in the utility model are conceived, equivalent structure made based on the specification and figures of the utility model
Transformation, or directly/be used in other related technical areas indirectly and be included in the scope of patent protection of the utility model.
