For example, in the embodiment shown in fig. 2, the water inlet pipeline 11 and the water discharge pipeline 13 are both connected to the left side of the heat exchanger 12 in fig. 2, and the first protecting plate 31 is provided with a plurality of strip-shaped avoiding openings 311, so that an operator can install the water inlet pipeline 11 and the water discharge pipeline 13 at the same time on one side of the heat exchanger 12, and the pipeline installation process is simpler and more convenient. Meanwhile, the heat exchanger 12 can be inserted into the limiting slot 41 through the right side of the heat exchanger, so that the heat exchanger is pre-positioned by the limiting slot 41, and then an operator can connect the water inlet pipeline 11 and the water drainage pipeline 13 with the left side of the heat exchanger 12, so that the heat exchanger 12 is simple and rapid to install and operate. Wherein the left side of the heat exchanger 12 refers to the direction indicated by the left arrow in fig. 2.
In the present embodiment, as shown in fig. 5, the air conditioner 100 preferably further includes a plurality of second adapters 52. The second adapter 52 is arranged between the strip-shaped evasion port 311 and the heat exchanger 12. One side of the second adaptor 52 is adapted to sealingly connect with the edge of the strip-shaped relief opening 311. The second side of the second adapter 52 is fixedly connected to one side of the heat exchanger 12. The water inlet line 11 and the water outlet line 13 pass through the second adaptor 52. Therefore, the second adaptor 52 can both fixedly connect the heat exchanger 12 and the first protective plate 31, and can also seal the gap between the heat exchanger 12 and the avoiding through hole, so as to avoid the wind flowing out from the gap between the heat exchanger 12 and the avoiding through hole, which results in reducing the heat exchange efficiency of the air conditioner 100.
In the present embodiment, the casing 2 preferably includes a base frame 23, and a plurality of panels 24 covering the periphery and upper and lower sides of the base frame 23. To facilitate the disassembly and assembly of the heat exchanger 12, a plurality of panels 24 are preferably removably provided on the base frame 23. The detachable connection between the panel and the base 23 is preferably, but not limited to, a riveted, snap or threaded connection. For example, in the present embodiment, the faceplate 24 is screwed to the base 23 through an adapter. A plurality of columns 25 are provided at intervals in the longitudinal direction of the base frame 23, and the panels 24 and the columns 25 are provided alternately in the longitudinal direction of the housing 2. The lateral plate structure of the heat exchanger 12 is fixedly connected to the housing by means of a support, which prevents the heat exchanger 12 from moving relative to the housing 2. The support is preferably, but not limited to, a sheet metal part.
In summary, the air conditioner 100 according to the embodiment of the present invention can overcome the defects that the structure of the whole air conditioner 100 is changed when the power of the air conditioner 100 is adjusted in the prior art, and the usage environment is single, has strong versatility, and can reduce the waste of manpower and material resources caused by redesigning the air conditioner 100.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
