[0043] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0044] like Figures 1 to 3 As shown, an embodiment of the utility model provides an air cooling device, which includes a housing 10, an air cooling assembly and a centrifugal blade 30. The housing 10 is provided with an air inlet channel 11, an air cooling chamber 12 and an air outlet 13 which are connected in sequence. A sand outlet 14 is provided at one end of the air inlet channel 11 close to the air cooling chamber 12 to discharge the sand and dust in the air inlet channel 11. The air cooling assembly includes a fan 20, which is installed in the air cooling chamber 12. The centrifugal blade 30 is arranged in the air inlet channel 11, and the centrifugal blade 30 is located upstream of the sand outlet 14, and the rotation axis direction of the centrifugal blade 30 is the same as the axis direction of the air inlet channel 11. In this embodiment, the centrifugal blade 30 is a spiral blade. When the wind enters the second channel 112 from the first channel 111, the wind speed will increase, and the wind will spirally move along the outer edge of the centrifugal blade 30. Due to the high density of the sand and dust, under the action of the centrifugal force of the centrifugal blade 30, the sand and dust flow out of the air inlet channel 11 at the sand outlet 14.
[0045] By applying the technical solution of the utility model, when the air cooling device of the present solution is used in a desert area, dust is easily sucked into the air inlet channel 11. Under the action of the centrifugal force of the centrifugal blades 30, the dust in the air inlet channel 11 will be discharged from the air inlet channel 11 through the sand discharge port 14, reducing the possibility of dust entering the air cooling chamber 12. In the traditional technical solution, dust-proof cotton is usually arranged in the air inlet channel, but the air permeability of the dust-proof cotton is poor, which will affect the air volume entering the air cooling chamber and the air cooling effect. In addition, the dust-proof cotton is easily blocked by dust. In order to reduce or avoid the situation where the dust-proof cotton is blocked, the staff needs to replace the dust-proof cotton regularly, which is costly. Compared with the traditional technical solution, the setting of the centrifugal blades 30 of the present solution can separate the dust and dust without affecting the air intake and does not need to be replaced regularly.
[0046] This solution does not impose any specific limitation on the location of the air inlet channel 11 .
[0047] like Figure 1 and Figure 4 As shown, in this embodiment, the air inlet channel 11 is arranged on the side of the air cooling chamber 12 .
[0048] This solution does not limit the specific number of the air inlet channels 11.
[0049] like Figure 1 and Figure 4 As shown, in this embodiment, two groups of air inlet channels 11 are provided, and the two groups of air inlet channels 11 are respectively provided at two ends in the length direction of the box body 10. Each group of air inlet channels 11 is provided with a plurality of air inlet channels 11, and the air inlet channels 11 extend along the length direction of the box body 10, and the plurality of air inlet channels 11 in each group are distributed at intervals along the width direction of the box body 10. Such a configuration can ensure the air intake volume and the air cooling effect.
[0050] This solution does not limit the number and location of the exhaust ports 13.
[0051] like Figure 2 and Figure 6 As shown, further, multiple exhaust ports 13 are provided, and multiple exhaust ports 13 are provided at the top of the air cooling chamber 12, and specifically, multiple exhaust ports 13 are provided at the center position of the top of the box body 10. In this embodiment, three exhaust ports 13 are provided, and the three exhaust ports 13 are spaced apart along the width direction of the box body 10. A fan 20 is provided at each exhaust port 13. Such an arrangement can increase the exhaust volume and improve the air cooling effect. In addition, the air inlet channel 11 is provided on the side of the air cooling chamber 12, and the exhaust port 13 is provided at the top of the air cooling chamber 12. Such an arrangement can ensure the rationality of the structural design of the box body 10 and improve the ventilation effect.
[0052] like Figure 2 and Figure 3 As shown, specifically, the air inlet channel 11 includes a first channel 111 and a second channel 112 which are sequentially connected along the direction from the air inlet channel 11 to the air cooling chamber 12. The ventilation area of the first channel 111 is greater than the ventilation area of the second channel 112, and the centrifugal blades 30 are arranged in the second channel 112. In this way, along the air flow direction, when the wind flows through the air inlet channel 11, according to the Venturi effect, the wind speed will increase when the wind flows from the wide air duct to the narrow air duct, which can enhance the centrifugal effect of the centrifugal blades 30, enhance the effect of wind and sand separation, and reduce the possibility of sand and dust entering the air cooling chamber 12.
[0053] Furthermore, the ventilation area of the end of the first channel 111 away from the second channel 112 is larger than the ventilation area of the end of the first channel 111 connected to the second channel 112. This arrangement can increase the amount of air entering the air inlet channel 11 and improve the air cooling effect.
[0054] In some embodiments of the present solution, the ventilation area of the first channel 111 gradually decreases along the direction from the first channel 111 to the second channel 112, that is, the first channel 111 is a tapered channel. This arrangement can improve the smoothness of the flow of wind and sand from the first channel 111 to the second channel 112, so that the wind speed gradually increases in the first channel 111.
[0055] In some other embodiments of the present solution, along the direction from the first channel 111 to the second channel 112 , the first channel 111 forms a stepped channel with a successively decreasing diameter.
[0056] Furthermore, the air inlet channel 11 further includes a third channel 113 , which is connected to an end of the second channel 112 away from the first channel 111 , and a ventilation area of the third channel 113 is greater than a ventilation area of the second channel 112 .
[0057] In this solution, the ventilation area of the end of the third channel 113 away from the second channel 112 is larger than the ventilation area of the end of the third channel 113 connected to the second channel 112. This arrangement can reduce the noise of the air inlet channel 11.
[0058] In some embodiments of the present solution, the ventilation area of the third channel 113 gradually increases along the direction from the second channel 112 to the third channel 113, that is, the third channel 113 is a tapered channel. This arrangement can improve the smoothness of the air flowing from the third channel 113 to the air cooling chamber 12.
[0059] In some other embodiments of the present solution, along the direction from the second channel 112 to the third channel 113 , the third channel 113 forms a stepped channel with a diameter that increases sequentially.
[0060] In this embodiment, the second channel 112 includes a mounting channel 1121 and a transition channel 1122 which are connected in sequence from the first channel 111 to the second channel 112. The centrifugal blade 30 is arranged in the mounting channel 1121. The taper of the transition channel 1122 is smaller than the taper of the mounting channel 1121. A sand discharge port 14 is formed between the mounting channel 1121 and the transition channel 1122. The other end of the transition channel 1122 is connected to the third channel 113. In this embodiment, the end of the transition channel 1122 away from the third channel 113 is penetrated in the mounting channel 1121, and an annular sand discharge port 14 is formed between the outer side wall of the transition channel 1122 and the inner side wall of the mounting channel 1121. The setting of the annular sand discharge port 14 facilitates the outflow of sand and dust.
[0061] In this embodiment, the ventilation area of the transition channel 1122 gradually increases along the direction from the installation channel 1121 to the transition channel 1122. Such a configuration can improve the smoothness of the air flowing from the transition channel 1122 to the third channel 113.
[0062] Furthermore, the air cooling device further comprises a first wire mesh 40, which is arranged at the air inlet of the air inlet channel 11. The arrangement of the first wire mesh 40 can further block sand and dust, and further reduce the possibility of sand and dust entering the air cooling chamber 12.
[0063] like Figure 1 , Figure 2 and Figure 6 As shown, specifically, the air cooling device includes an air inlet duct, and the air inlet duct includes a first duct, a mounting duct, a transition duct and a third duct. Among them, the first duct forms a first channel 111, the mounting duct forms a mounting channel 1121, the transition duct forms a transition channel 1122, and the third duct forms a third channel 113. The first duct and the mounting duct are integrally formed, and the transition duct and the third duct are integrally formed. Such an arrangement facilitates the formation of an air inlet channel 11, realizes the independent arrangement of multiple air inlet channels 11, and facilitates the smoothness of the discharge of sand and dust in the air inlet channel 11 from the sand discharge port 14 to the box body 10.
[0064] like Figure 5 As shown, in this embodiment, a main sand discharge port 15 is also provided at the bottom of the box body 10. The provision of the main sand discharge port 15 facilitates the discharge of sand and dust in the box body 10 to the outside of the box body 10, thereby reducing the possibility of excessive accumulation of sand and dust in the box body 10.
[0065] like Figures 1 to 4As shown, specifically, the two ends of the box body 10 along the length direction are open and form a mounting opening 101, and a plurality of air inlet ducts are arranged in the mounting opening 101 at intervals along the length direction of the box body 10. The first wire mesh 40 is arranged at the mounting opening 101 and is located on a side of the plurality of air inlet ducts away from the air cooling chamber 12. Such an arrangement facilitates the installation of the first wire mesh 40 and the plurality of air inlet ducts.
[0066] like Figure 1 and Figure 2 As shown, further, the air cooling device also includes a second wire mesh 70 , which is arranged at the air outlet 13 to prevent debris from falling into the air cooling chamber 12 .
[0067] like Figure 2 and Figure 6 As shown, the second embodiment of the utility model provides an electrical cabinet, in which electrical components are installed, and the electrical cabinet includes the above-mentioned air cooling device.
[0068] Furthermore, the electrical cabinet includes a cabinet body 50, a liquid cooling component and a heat dissipation portion 60. The cabinet body 10 is arranged on the cabinet body 50. The cabinet body 50 is provided with a liquid cooling cavity, and the liquid cooling cavity is used to install the electrical components. The liquid cooling component is arranged in the liquid cooling cavity, and the liquid cooling component is used to cool the electrical components. The heat dissipation portion 60 is arranged in the air cooling cavity 12 of the cabinet body 10, and the heat dissipation portion 60 exchanges heat with the liquid cooling component. The arrangement of the liquid cooling component and the heat dissipation portion 60 can further improve the heat dissipation effect of the electrical components inside the electrical cabinet.
[0069] In this embodiment, the fan 20, the heat dissipation portion 60 and the air inlet passage 11 are distributed along the length direction of the box body 10. The heat dissipation portion 60 is arranged obliquely, with one end of the heat dissipation portion 60 tilted downward toward the air inlet passage 11, and the other end of the heat dissipation portion 60 tilted upward toward the fan 20. Such an arrangement can increase the heat dissipation area of the heat dissipation portion 60 as much as possible, thereby improving the heat dissipation effect.
