Detailed Implementation

[0022] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that the embodiments of the invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0023] Figure 1 This is a schematic diagram of a wind turbine support structure provided in an embodiment of the present invention. (See attached diagram.) Figure 1 At the same time, combined Figures 2 to 5 The fan support structure in this embodiment will be described in detail. The fan support structure 30 may include support rods 32, a base frame 31, and an air guide assembly receiving part 33. The support rod 32 includes a bottom end and a top end. The base frame 31 may be polygonal, with the corners of the polygon connected to the bottom end. The air guide assembly receiving part 33 is connected to the top end and has a space for the fan 20 blades to be recessed, through which external air enters via at least two support rods 32. This facilitates the fan obtaining more airflow, thereby improving the operating efficiency of the chiller, and also reduces the overall height of the air conditioner.

[0024] Understandably, the fan support structure 30 is positioned next to at least one air inlet. The size of the air inlet is adapted to the size of the fan support structure. Outside air first enters through the air inlet, then flows through the space, and finally is exhausted by the air guide assembly consisting of the manifold 10 and the fan 20. When the unit includes multiple air inlets, the air inlets are arranged around the sides of the fan support structure 30. For example, when there are two air inlets and these two air inlets are respectively located on adjacent side plates, they are arranged in an L-shape around the two sides of the fan support structure 30.

[0025] In one embodiment, the air guide assembly receiving part 33 is a plate-shaped structure manufactured using an integral forging process. A circular fan blade mounting hole is provided in the center of the plate for mounting the fan blade. The recessed design of the fan blade means that the lowest point of the fan blade can be lower than the lowest edge of the mounting hole.

[0026] In one embodiment, the air guide assembly receiving part 33 is fixedly connected to the air collector 10, and the air collector 10 is fixedly connected to the fan 20. The fan 20 can also be installed in an internal enclosure, which is not limited here.

[0027] In another embodiment, the bottom frame 31 is circular, and a plurality of support rods 32 are spaced apart on the annulus of the bottom frame 31.

[0028] In some embodiments, the air guide assembly receiving portion 33 includes two receiving sub-parts, namely a first receiving sub-part 331 and a second receiving sub-part 332. A space is provided between the two oppositely arranged and mutually spaced receiving sub-parts to accommodate the downward-sloping arrangement of the fan 20 blades. The design of the downward-sloping blades is similar to that in the above embodiments and will not be described again.

[0029] In some embodiments, the base frame 31 is formed by a plurality of horizontal plates. Taking the second receiving part 332 as an example, the second receiving part 332 includes two partition ends. The partition ends 333 extend parallel to the length direction of the horizontal plate 311 on the same side to the support end 334 of the support rod 32. The partition ends 333 are connected to one end of the inclined connecting rod 34 by a ball joint. The track 3111 in the middle region of the horizontal plate 311 on the same side is connected to the other end of the inclined connecting rod 34 by sliding damping. The angle formed between the partition ends 333 and the support end 334 and the inclined connecting rod 34 is an obtuse angle. The number of horizontal plates can be three or four, which is not limited here.

[0030] It is worth noting that multiple inclined sliding links form a trapezoidal support, which not only makes the structure more stable, but also provides sliding displacement that can dissipate vibration energy within a certain range. In addition, since there are no other structures to block the wind besides the inclined links, the overall wind resistance is reduced.

[0031] In some embodiments, the tilting link 34 includes a second rod 341, one end of which is provided with a damping block 342, and the track 3111 includes a locking gap for the damping block 342 to slide.

[0032] In some embodiments, the support rod 32 is vertically arranged.

[0033] In another embodiment, the support rod 32 is inclined toward the central axis of the fan rotation.

[0034] In some embodiments, the support rod 32 is a spring damping rod. Exemplarily, the spring damping rod includes a spring, a damper, and a piston rod connecting the spring and the damper.

[0035] In some embodiments, the support rod 32 includes a first rod body 321 and a groove. The inner side of the groove is tightly fitted to 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 outer shell of the groove serves as the bottom end. A damping element 322 of a predetermined depth is embedded in the upper and middle parts of the inner side of the groove, contacting and surrounding the side wall of the first rod body. A damping element 322 of a predetermined depth is embedded in the bottom of the groove, contacting and surrounding the bottom of the first rod body.

[0036] Specifically, the trough is cylindrical.

[0037] As an optional implementation, when viewed along the cross-sectional direction of the support rod 32, the bottom damping member is concave and contacts the spherical bottom of the first rod 321, the middle damping member is circular and in close contact with the side wall of the first rod 321, and the upper damping member is circular and in close contact with the side wall of the first rod 321.

[0038] It is worth noting that the first rod has damping to suppress vibration in all directions and on all layers, giving the fan a certain operating range and consuming the energy generated by vibration, thus preventing the vibration from being transmitted to the casing.

[0039] In some embodiments, the surface of the air guide assembly receiving part 33 is provided with bolt fixing holes 35 and first drain holes 36, and the bolt fixing holes 35 and first drain holes 36 are spaced apart by a first preset distance.

[0040] In some embodiments, the surface of the air guide assembly receiving part 33 is provided with a second drain hole 37, the bolt fixing hole 35 and the second drain hole 37 are provided at a second preset distance apart, the first preset distance is less than the second preset distance, and the diameter of the first drain hole 36 is less than the diameter of the second drain hole 37.

[0041] In some embodiments, the present invention provides a top-mounted chiller, which includes a manifold 10, a fan 20, and any of the fan support structures 30 described in the above embodiments. The manifold 10 and the fan 20 are mounted on the fan support structure 30, making the overall structure more compact. Preferably, the fan 20 is an axial flow fan.
