It is dynamic.Therefore, it is possible to reduce loss when supply air 41 is collided with heat conducting pipe 11.
For the surface of heat conducting pipe 11, the interconnecting piece with the connection of the 2nd fin 22 leaves with from the interconnecting piece
Side between the position of predetermined distance, being collided with the supply air 42 from the 2nd fan 32, becomes inclination
Face 12.Therefore, when the supply air 42 from the 2nd fan 32 is collided with heat conducting pipe 11, supply air 42 will not be detained and energy
Enough to be flowed along inclined surface 12, therefore, it is difficult to interfere the flowing of supply air 42.Therefore, it is possible to reduce supply air 42 and heat conduction
Loss when pipe 11 collides.In addition, in the present embodiment, inclined surface 12 is for example formed as section circular shape etc. outside
The curve form of side protrusion.Therefore, it is possible to which the flow path section of the refrigerant flow path 11a in heat conducting pipe 11 product is ensured to be larger.
Here, as described above, in heat conducting pipe 11, flat pattern is presented (more in the section vertical with refrigerant flow path 11a
Specifically it is approximate oblong shape).In addition, heat conducting pipe 11 so that the long side direction of section along from the 1st fan 31 and the 2nd

Previous outdoor unit 300 for example has the shell 301 of rectangular shape.The inside of the shell 301 is by demarcation strip 302
It is divided into supply fan room 303 and Machine Room 304.
It is accommodated with fan 330 and outdoor heat exchanger 310 in supply fan room 303.Outdoor heat exchanger 310 is with along shell
The mode of the back part 301b and side surface part 301c of body 301, are formed as approximate L-shaped in plan view.In addition, overleaf
The range opposed with outdoor heat exchanger 310 of portion 301b and side surface part 301c, is formed with suction inlet 305.
As shown in Figure 7 and Figure 8, outdoor heat exchanger 310 has：The multiple fins 312 being rectangle；And in inside
Multiple heat conducting pipes 311 with the refrigerant flow path 311a flowed for refrigerant.Multiple fins 312 so that long side direction along
The mode of upper and lower directions configures.Moreover, above-mentioned multiple fins 312 are transversely arranged side by side in a manner of interval as defined in separating.
In addition, (long side direction of fin 312) is set multiple heat conducting pipes 311 side by side along the vertical direction in a manner of interval as defined in separating
Set, and along fin 312 and set direction run through each fin 312.In addition, in previous outdoor unit 300, as previous room
Heat conducting pipe 311 used in outer heat-exchanger 310 is (detailed in flat pattern using the section vertical with refrigerant flow path 311a
For be oblong shape) flat tube.In addition, being configured to form multiple notch 312a in a side edge part of each fin 312, lead to
It crosses and heat conducting pipe 311 is inserted into each notch 312a, so as to make heat conducting pipe 311 through fin 312.
The fan 330 of air is supplied with the side opposed with the front surface part 301a of shell 301 towards outdoor heat exchanger 310
Formula is arranged.In the range opposed with fan 330 of front surface part 301a, it is formed with outlet 306.In addition, connecting in fan 330
It is connected to the motor 330a that rotation driving is carried out to the fan 330.In addition, the rotating speed of motor 330a is (in other words as turning for fan 330
Speed) it is controlled by being accommodated in the control device 350 of Machine Room 304.
By making motor 330a carry out rotation driving, thus from fan 330 towards the supply air of outdoor heat exchanger 310
340 directions flowed are the direction of hollow arrow.Specifically, by making motor 330a carry out rotation driving, thus air
It is flowed into from the suction inlet 305 for being formed in back part 301b and side surface part 301c towards outdoor heat exchanger 310, and the air
It is discharged from the outlet 306 for being formed in front surface part 301a to outside shell 301.That is, in the outdoor unit 300 of previous air conditioner
In, outdoor heat exchanger 310 is only supplied air from a direction.Therefore, in the outdoor unit 300 of previous air conditioner, come
From the supply air 340 of fan 330 in 311 perimeter of heat conducting pipe of outdoor heat exchanger 310 as shown in Fig. 9.
