DETAILED DESCRIPTION

[0028] Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments, however, can be implemented in many different forms and should not be construed as limited to the implementations set forth herein; rather, these implementations are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. Like reference numerals refer to like elements throughout the figures, and thus a detailed description of the same will not be repeated.

[0029] Figure 1 The three-dimensional view of a flow guide cover is schematically provided by the embodiment of the utility model. Refer to Figure 1 , and combine with Figures 2 to 7The fairing in the embodiment is described in detail. The fairing 100 comprises a connecting portion 105, which comprises a closed inner edge 104 and a closed outer edge 103. The inner edge 104, which forms the air inlet 21, is raised by a first height in the air outlet direction A, and the inner edge, which surrounds the raised top edge, forms the inner air outlet 22. The outer edge 103, which is raised by a second height in the air outlet direction A, surrounds the raised top edge to form the outer air outlet 23.

[0030] The embodiment can disperse the load acting on the structure to the inner wall and the outer wall, reduce local stress concentration, and avoid vibration displacement deformation of the fairing.

[0031] In some possible embodiments, the fan is adjusted in frequency during operation according to operating conditions. Vibration is generated during frequency conversion. Generally, the fan is arranged on a support assembly, and the support assembly is connected to the fairing, so that the vibration is transmitted to the fairing. In other cases, the fan is directly connected to the fairing, so that the vibration is directly transmitted to the fairing. Alternatively, the vibration of the fan is first transmitted to the unit shell, and then transmitted to the fairing. The above examples are only used to explain different cases that may cause the fairing to vibrate.

[0032] In one embodiment, the surface of the fan cover 109 is fixedly provided with a connecting rod 200, one end of the connecting rod 200 is fixedly connected with the top end of a fan body 201. The top of the support 102 comprises a corresponding bolt fixing hole, the other end of the connecting rod 200 has a fixing gap, the fixing gap, the bolt fixing hole 108 and the support bolt fixing hole are sequentially and one-to-one corresponding, and a fixing member penetrates through them to realize fixed connection, and the fixing member is a bolt and a nut.

[0033] In some embodiments, the fan blade 101 is sleeved on the inner edge around the protrusion and rotates around the fan axis. The airflow generated by the axial fan blade enters the fairing 100 through the air inlet 21, and the airflow is guided by the fairing body, and then flows out of the fairing 100 through the inner air outlet 22 and the outer air outlet 23. It is worth noting that the guided diffusion air duct can reduce wind resistance, reduce wind noise, and make the fan more efficient in heat dissipation.

[0034] In some embodiments, the outer edge 103 is circular, and the inner edge 104 is circular. Alternatively, the outer edge 103 is polygonal, and the inner edge 104 is polygonal. Alternatively, the outer edge 103 is polygonal, and the inner edge 104 is circular. Alternatively, the inner edge 104 is polygonal, and the outer edge 103 is circular.

[0035] In some embodiments, the connecting portion 105 is provided with a water inlet hole 106 and a bolt fixing hole 108 at intervals. Thus, the possibility of corrosion of the fastening bolt by water is reduced.

[0036] In some embodiments, the connecting portion 105 is a plate-shaped circular ring.

[0037] In some embodiments, the bolt fixing holes 108 are evenly arranged on the surface of the connecting part 105. The downspout hole 106 includes: a first downspout sub-hole 1061 evenly arranged on the surface of the connecting part 105; and a second downspout sub-hole 1062 arranged on one side close to the bolt fixing hole 108. The first downspout sub-hole 1061 and the bolt fixing hole 108 are arranged at a first preset distance, the second downspout sub-hole 1062 and the bolt fixing hole 108 close to it are arranged at a second preset distance, the first preset distance is greater than the second preset distance, and the hole diameter of the first downspout sub-hole 1061 is greater than the hole diameter of the second downspout sub-hole 1062. It is worth noting that the first downspout sub-hole is responsible for processing the main water flow, so the amount and size of impurities and particles in the water flow facing it are more than those of the second downspout sub-hole. Since the first downspout sub-hole “intercepts” most of the impurities and particles, it reduces the risk of the second downspout sub-hole being blocked, thereby ensuring the drainage efficiency of the important part.

[0038] Optionally, the second downspout sub-hole 1062 is arranged on both sides close to the bolt fixing hole 108.

[0039] In some embodiments, R1≥2R2, R1 represents the hole diameter of the first downspout sub-hole 1061, and R2 represents the hole diameter of the second downspout sub-hole 1062.

[0040] In some embodiments, the central angle between the nearest adjacent first downspout sub-hole 1061 and the bolt fixing hole 108 on the surface of the connecting part 105 is (360 / 4N)°±6°, 3≤N≤5, N represents the number of bolt fixing holes 108, and the number of bolt fixing holes 108 is the same as the number of first downspout sub-holes 1061. It is worth noting that the bolt fixing hole is a key stress point of the connecting part, and larger downspout holes cannot be arranged too close to these holes to avoid weakening the structural strength. However, if the downspout holes are arranged too far apart, their efficiency in preventing blockage will also be reduced. Therefore, by establishing the relationship between the central angle of the first downspout sub-hole and the bolt fixing hole, the anti-blocking requirement can be met, and the weakening of the structural strength can be avoided.

[0041] It can be understood that the central angle between the two adjacent first downspout sub-holes 1061 on the surface of the connecting part 105 is (360 / N)°, and the same applies to the bolt fixing hole 108.

[0042] Optionally, the central angle between the adjacent second downspout sub-hole 1062 and the bolt fixing hole 108 on the surface of the connecting part 105 ranges from 3° to 8°.

[0043] Optionally, the second downspout sub-hole 1062 does not necessarily have to be arranged around the center, and its position can be arranged close to the bolt fixing hole 108.

[0044] In some embodiments, the outer edge around the raised top edge is provided with a water baffle 107, the outer edge 1072 and the inner edge 1071 of the water baffle extend in opposite directions.

[0045] In this embodiment, the upper plane of the water baffle 107 is closely fitted with the outer edge of the air inlet of the unit top cover plate 202, and a sponge 203 is clamped therebetween. It is worth noting that when the fan is running in the rain, part of the rainwater will be blown to the outer edge around the raised top after falling, and will flow upward against the flow. In this case, rainwater may flow into the electrical control area inside the unit along the gap between the outer edge around the raised top and the top cover. The water baffle effectively avoids the possibility of rainwater entering the unit interior along these gaps when flowing upward against the flow.

[0046] In another embodiment, the upper plane of the water baffle is not horizontal, the outer edge is higher than the inner edge, and the outer edge is fitted with the unit top cover plate.

[0047] In some embodiments, the utility model embodiment provides a top-mounted cold machine, which comprises a guide air component, the guide air component comprises a fan blade 101 and any one of the guide vanes 100 of the above-mentioned embodiments.
