[0026] Figure 1 is a kind of schematic view of fan support structure provided in the utility model embodiment. Refer to Figure 1 Also, in combination with Figures 2 to 5 , the fan support structure in the embodiment is described in detail.The fan support structure 30 can include support rod 32, bottom frame 31 and air guide assembly receiving portion 33.Support rod 32 includes bottom end and top end.Bottom frame 31 can be polygonal, and the corner point of polygon is connected with bottom end.Air guide assembly receiving portion 33 is connected with top end and is provided with space matched with the blade of fan 20 sinking, wherein, external air enters the space through at least two support rods 32.In this way, the fan can obtain more flowing air, thereby improving the operating efficiency of the chiller, in addition, the overall height of the air conditioner is also reduced.

[0027] It can be understood that the fan support structure 30 is arranged beside at least one air inlet. The size of the air inlet is matched with the size of the fan support structure. The external air first enters through the air inlet, then flows through the space, and finally is discharged by the air guide assembly composed of the collector 10 and the fan 20. When the unit includes multiple air inlets, the air inlets are arranged around the side of the fan support structure 30. Exemplarily, when there are two air inlets and the two air inlets are arranged on the adjacent side plates respectively, they are arranged in an L-shaped layout around the two sides of the fan support structure 30.

[0028] In one embodiment, the air guide assembly receiving portion 33 is a plate-shaped structure made by an integrated forging forming process. The plate is centrally provided with a circular fan blade placing hole for placing the fan blade. The design of the sunken fan blade means that the lowest point of the fan blade can be lower than the lowest edge of the placing hole.

[0029] In one embodiment, the air guide assembly receiving portion 33 is fixedly connected with the collector 10, and the collector 10 is fixedly connected with the fan 20. The fan 20 can also be in the form of in-box hoisting, which is not limited here.

[0030] In another embodiment, the bottom frame 31 is circular, and a plurality of support rods 32 are arranged on the circular ring of the bottom frame 31 at intervals.

Taking the second receiving sub-portion 332 as an example, the second receiving sub-portion 332 includes two partitioning ends, the partitioning end 333 extends in parallel to the support end 334 of the support rod 32 along the length direction of the same side horizontal plate 311, the partitioning end 333 is connected with one end of the inclined connecting rod 34 through a spherical pair, the track 3111 in the middle region of the same side horizontal plate 311 is connected with the other end of the inclined connecting rod 34 through sliding damping, and the angle formed by the partitioning end 333 to the support end 334 and the inclined connecting rod 34 is obtuse. The number of horizontal plates can be three or four, which is not limited here.

[0033] It is worth noting that the plurality of inclined sliding connecting rods form a trapezoidal support, which not only makes the structure more stable, but also provides a sliding displacement that can consume vibration energy within a certain range.

[0035] In some embodiments, the support rod 32 is vertically arranged.

[0036] In another embodiment, the support rod 32 is arranged obliquely towards the rotation axis of the fan.

[0037] In some embodiments, the support rod 32 is a spring damping rod. Exemplarily, the spring damping rod comprises a spring, a damper, and a piston rod connecting the spring and the damper.

[0038] In some embodiments, the support rod 32 comprises a first rod body 321 and a groove body, the inner side of the groove body is tightly fitted with the side wall of the first rod body, the top of the first rod body serves as the top end, and the bottom of the shell of the groove body serves as the bottom end. The upper part and the middle part of the inner side of the groove body are each embedded with a damping member 322 of a preset depth and in contact with and surrounding the side wall of the first rod body, and the bottom of the inner side of the groove body is embedded with a damping member 322 of a preset depth and in contact with and surrounding the bottom of the first rod body.

[0041] It is worth noting that the first rod body has damping in all directions and all layers to suppress vibration, give the fan a certain operating range and consume the ability generated by vibration, and avoid transmitting vibration to the casing.

[0042] In some embodiments, the surface of the air guide assembly receiving portion 33 is provided with a bolt fixing hole 35 and a first water falling hole 36, and the bolt fixing hole 35 and the first water falling hole 36 are arranged at a first preset distance.
