And if set up connecting line at the free end of first heat transfer portion and second heat transfer portion, then need be in the same place connecting line welding, and be the rigidity, when needs take first heat transfer portion and second heat transfer portion apart, need weld the pipeline that is good and tear open and weld, maintenance efficiency is low, and the damage that causes connecting line influences connecting line's life, and the mode of setting shown in fig. 2 can realize maintaining and maintaining more conveniently. Alternatively, a damping member is disposed in the connection structure, so that a certain friction force is generated between the first heat exchanging part 1 and the second heat exchanging part 2, and the effect of fixing the first heat exchanging part 1 and the second heat exchanging part 2 can also be achieved.
Wherein, the specific connection mode of the free ends of the first heat exchanging part 1 and the second heat exchanging part 2 is not limited, and in one embodiment, when the free ends of the first heat exchanging part 1 and the second heat exchanging part 2 are positioned at the second position, the end surface of the free end of the first heat exchanging part 1 is butted with the end surface of the free end of the second heat exchanging part 2, so that the heat exchanging efficiency and the attractive appearance can be ensured, in another embodiment, as shown in fig. 1, when the free ends of the first and second heat exchanging parts 1 and 2 are at the second position, a gap is arranged between the end surface of the free end of the first heat exchanging part 1 and the end surface of the free end of the second heat exchanging part 2, be provided with detachable baffle 7 in clearance department, block the clearance through baffle 7, so, can enough reduce the machining precision of first heat transfer portion 1 and second heat transfer portion 2, reduction in production cost improves production efficiency, can guarantee again that heat exchange efficiency and appearance are pleasing to the eye.
Of course, it is understood that other heat exchanging portions may be provided in addition to the first heat exchanging portion 1 and the second heat exchanging portion 2, for example, a third heat exchanging portion may be provided, a first end of the first heat exchanging portion 1 and a first end of the third heat exchanging portion are connected via a first connecting structure, and the first heat exchanging portion 1 is capable of rotating relative to the first connecting structure; and/or, the first end of the second heat exchanging part 2 is connected with the second end of the third heat exchanging part through the second connecting structure, and the second heat exchanging part 2 can rotate relative to the second connecting structure, so that the third heat exchanging part can be fixed, and when the heat exchanger needs to be opened and closed, the first heat exchanging part 1 can be rotated only, or the second heat exchanging part 2 can be rotated only, and the first heat exchanging part 1 and the second heat exchanging part 2 can be rotated only.
Further, the invention also provides an air conditioner outdoor unit which adopts the heat exchanger. Specifically, as shown in fig. 2 and 3, the first heat exchanging portion 1 and/or the second heat exchanging portion 2 are bent or curved, the first heat exchanging portion 1 and the second heat exchanging portion 2 enclose to form an accommodating space 6, a fan 81, a compressor 82, an oil-gas separator 83, a gas-liquid separator 84, a four-way valve 85, a subcooler 86 and other devices of the outdoor unit can be disposed in the accommodating space 6, and the fan 81 is located above the other devices and is mounted in the heat exchanger through a fan bracket 87, and in order to improve the mounting reliability of the heat exchanger, a fixing nut can be further added to fix the heat exchanger. So, can make air condensing units's compact structure, heat exchange efficiency high, in addition, when needs maintain air condensing units, only need to take first heat transfer portion 1 and second heat transfer portion 2 apart, realize quick installation and after-sales maintenance.
Specifically, as shown in fig. 2 and 3, when the outdoor unit of the air conditioner is in normal operation, when maintenance is required, the refrigerant is firstly discharged, then the baffle 7 and the nuts for fixing the first heat exchanging part 1 and the second heat exchanging part 2 are detached as shown in fig. 4, the first heat exchanging part 1 and the second heat exchanging part 2 are opened by a certain angle, so that the maintenance personnel can conveniently check, maintain and replace the devices in the heat exchanger, after the maintenance is completed, the airtightness of the whole air conditioning system is detected, after the airtightness is qualified, the first heat exchanging part 1 and the second heat exchanging part 2 are closed, the baffle 7 is installed, the outdoor unit is restored, and the whole maintenance process is completed.
