[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] The energy storage inverter usually has an air duct, which is used to guide the air flow to achieve a cooling effect, to help dissipate heat and keep the temperature of the energy storage inverter within a safe range. Therefore, in the prior art, the air duct of the energy storage inverter is connected to the outdoor environment, and insects may enter the energy storage inverter through the air duct, which may cause the air duct to be blocked, affect the circulation of the air duct, and even damage the components inside the energy storage inverter; and the air contains various dust, particles and impurities. If these dusts enter the air duct, they may accumulate inside the energy storage inverter and even damage the electronic components inside the energy storage inverter.

[0030] Therefore, in order to solve the above technical problems, the utility model provides a curved air duct and an energy storage converter. The utility model sets a dustproof device and an insect-proof device in the curved air duct to achieve the functions of insect-proof, dust-proof and waterproof. The curved air duct provided by the utility model can be used in the energy storage converter.

[0031] Embodiment 1

[0032] Please refer to Figures 1 to 10 The curved air duct of the embodiment of the utility model comprises: a curved pipe housing 10, a dustproof device 20 and an insect-proof device 30. A curved ventilation duct 11 is formed in the curved pipe housing 10, and the curved pipe housing 10 has an air inlet 12 and an air outlet 13 connected to the ventilation duct 11, and the air inlet 12 and the air outlet 13 of the curved pipe housing 10 are arranged adjacent to each other; the dustproof device 20 is arranged at the air inlet 12 of the curved pipe housing 10; the insect-proof device 30 is arranged obliquely in the ventilation duct 11, and the angle formed by the insect-proof device 30 and the air inlet 12 is greater than the angle formed by the insect-proof device 30 and the air outlet 13.

[0033] Therefore, the curved air duct of the embodiment of the utility model is provided with a dustproof device 20 at its air inlet 12. The setting of the dustproof device 20 can reduce the entry of dust, particulate matter and other debris into the curved air duct and the energy storage inverter device, thereby keeping the curved air duct and the energy storage inverter clean and avoiding blockage of the curved air duct, thereby achieving the effect of improving the stability and reliability of the curved air duct and the energy storage inverter and increasing the service life.

[0034] Furthermore, the curved air duct of the embodiment of the present application is provided with an insect-proof device 30 in its ventilation duct 11, which can reduce the possibility of insects entering the curved air duct and the energy storage inverter, thereby achieving an insect-proof effect. And the angle formed by the insect-proof device 30 and the air inlet 12 is greater than the angle formed by the dust-proof device 20 and the air outlet 13, that is, the insect-proof device 30 is arranged at a position close to the air outlet 13. Because the air outlet 13 is the position where air flows out of the ventilation duct 11, insects are more likely to enter the system through the air outlet 13. Therefore, setting the insect-proof device 30 in the curved air duct close to the air outlet 13 can improve the insect-proof effect, reduce the possibility of insects entering the curved air duct and the energy storage inverter, avoid clogging the curved air duct, and achieve the effect of improving the stability and reliability of the curved air duct and the energy storage inverter, and increasing the service life.

[0035] In addition, by installing the dustproof device 20 and the insect-proof device 30 in the ventilation duct 11, the possibility of water vapor entering the curved air duct and the energy storage inverter can be reduced, and the waterproof function can be achieved simultaneously, thereby improving the stability and reliability of the curved air duct and the energy storage inverter and increasing the service life.

[0036] And, if Figure 1 As shown, in order to ensure the ventilation effect of the curved air duct, the insect-proof device 30 is arranged obliquely in the ventilation duct 11 to reduce the resistance of the air in front of the insect-proof device 30, which helps to achieve the effect of maintaining the ventilation effect of the curved air duct.

[0037] Furthermore, the curved pipe shell 10 constitutes the main part of the curved air duct. Compared with a vertical shell, the curved pipe shell 10 can utilize space more effectively and can be installed along a curved path during installation, while the vertical shell may require more space to accommodate.

[0038] Embodiment 2

[0039] See also Figure 8 In some optional embodiments, the dustproof device 20 specifically includes: a first metal outer frame 21 and a double-sided aluminum mesh 22. The double-sided aluminum mesh 22 is disposed in the first metal outer frame 21.

[0040] Specifically, the first metal outer frame 21 is the outer frame structure of the dustproof device 20, which is used to support and fix the entire dustproof device 20. And the size of the first metal outer frame 21 is specifically matched with the air inlet 12 of the curved air duct to ensure that the dustproof device 20 can be correctly installed at the air inlet 12. In addition, the first metal outer frame 21 is installed by closing, that is, the edge of the first metal outer frame 21 is fixed to the air inlet 12, and the first metal outer frame 21 is tightly fitted and fixed at the air inlet 12, so that the dustproof device 20 can be set close to the air inlet 12 of the curved air duct.

[0041] The double-sided aluminum mesh 22 is arranged in the first metal outer frame 21, that is, the first metal outer frame 21 is arranged outside the double-sided aluminum mesh 22, which can effectively fix the double-sided aluminum mesh 22; and the double-sided aluminum mesh 22 serves as a filter layer of the dustproof device 20 to effectively filter dust and impurities in the air.

[0042] The dustproof device 20 can be specifically dustproof cotton. Through the setting of dustproof cotton, dust, particulate matter and impurities can be filtered; and the dustproof cotton has good air permeability, and the setting of dustproof cotton in the ventilation duct 11 will not affect the air circulation and ventilation effect of the curved air duct; in addition, by setting the dustproof device 20 as dustproof cotton, moisture in the air can also be absorbed to achieve a waterproof effect, preventing the curved air duct and the energy storage converter from being damp.

[0043] In this way, by setting the dustproof device 20, flying dust and water vapor can be prevented from entering the energy storage converter, so that the energy storage converter can achieve the effect of IP65 protection level.

[0044] Embodiment 3

[0045] See also Figure 8In some optional embodiments, the size of the first metal outer frame 21 can be: 991×280×10mm. Of course, the size of the first metal outer frame 21 can be adjusted according to the size of the curved air duct. The double-sided aluminum mesh 22 is a mesh structure with double-sided openings and a density of 300ppi. The thickness of the double-sided aluminum mesh 22 is specifically 8mm, and its aperture size is 15×30mm.

[0046] Embodiment 4

[0047] See also Figure 8 In some optional embodiments, the surface of the first metal outer frame 21 is a flat surface. The surface of the first metal outer frame 21 is a flat surface and cannot have surface defects such as scratches and bumps. Because if there are scratches, bumps and other defects on the surface of the first metal outer frame 21, the surface of the first metal outer frame 21 will be uneven, thereby affecting its close connection with the double-sided aluminum mesh 22 or other components. This may cause air to bypass the dustproof device 20 and enter the inside of the curved air duct, thereby reducing the dustproof effect and affecting the normal operation of the curved air duct and the energy storage converter; and if there are defects on the surface of the first metal outer frame 21, it will also reduce the strength and stability of the first metal outer frame 21, making it easier to deform or damage during installation and use, which will lead to unstable fixation of the dustproof device 20 or a decrease in structural strength. Therefore, by keeping the surface of the first metal outer frame 21 flat, the dustproof effect of the dustproof device 20 can be maintained and the stability of the dustproof device 20 can be improved.

[0048] Embodiment 5

[0049] See also Figure 8 In some optional embodiments, the first metal outer frame 21 has a plurality of countersunk rivets 23 , and the first metal outer frame 21 is fixed at the air inlet 12 by the countersunk rivets 23 .

[0050] The first metal outer frame 21 is fixed by a plurality of countersunk rivets 23. Therefore, compared with the method of fixing with screws, the countersunk rivets 23 do not need to be pre-drilled on the first metal outer frame 21. The installation can be completed by simply using appropriate tools to drive the countersunk rivets 23 into the first metal outer frame 21, thereby eliminating the step of pre-drilling holes in the first metal outer frame 21, thereby saving time and labor costs. In addition, because the dustproof device 20 needs to be frequently flushed and replaced, the countersunk rivets 23 are used for fixing, which can achieve the effect of facilitating the replacement and flushing of the dustproof device 20.

[0051] Embodiment 6

[0052] See also Fig. 9 and Fig.10In some optional embodiments, the insect-proof device 30 includes: a second metal outer frame 31 and a plurality of insect-proof nets 32 , each of which is connected to the second metal outer frame 31 and is disposed in the second metal outer frame 31 .

[0053] Specifically, the second metal outer frame 31 constitutes the outer frame structure of the insect-proof device 30, which is used to support and fix the entire insect-proof device 30. The various insect-proof nets 32 in the second metal outer frame 31 constitute the main insect-proof module in the insect-proof device 30. The arrangement of the various insect-proof nets 32 can prevent insects and other small creatures from entering the interior of the curved air duct. The various insect-proof nets 32 are specifically composed of fine meshes, which can prevent insects from entering while allowing air to flow freely. Therefore, multiple insect-proof nets 32 are arranged in the second metal outer frame 31 and connected to the second metal outer frame 31, that is, a tight insect-proof barrier is formed in the ventilation duct 11.

[0054] Embodiment 7

[0055] See also Fig. 9 and Fig.10 In some optional embodiments, the second metal outer frame 31 has multiple first openings 33 and multiple screws 34, each screw 34 is correspondingly arranged in each first opening 33, and each insect-proof net 32 ​​is connected to the second metal outer frame 31 through each first opening 33 and each screw 34.

[0056] Specifically, as for the connection method between the second metal outer frame 31 and each insect-proof net 32, a plurality of first openings 33 are set around the edge portion of the second metal outer frame 31, and each screw 34 is correspondingly inserted into each first opening 33, and each screw 34 also passes through the edge of each insect-proof net 32, so that each insect-proof net 32 ​​can be fixedly connected to the second metal outer frame 31.

[0057] Furthermore, when the insect-proof net 32 ​​needs to be replaced and maintained, only the two screws 34 set on the second metal outer frame 31 need to be removed to remove each insect-proof net 32, and the insect-proof net 32 ​​can be cleaned and replaced, thereby achieving the effect of facilitating maintenance and shortening maintenance time.

[0058] Embodiment 8

[0059] See also Figure 8 , Fig. 9 and Fig.10 In some optional embodiments, the first metal outer frame 21 and the second metal outer frame 31 are both made of aluminum alloy. Specifically, the first metal outer frame 21 and the second metal outer frame 31 can be both made of aluminum oxide, but not limited thereto.

[0060] For the first metal outer frame 21 and the second metal outer frame 31, since aluminum alloy is generally lighter than other metals, the entire dustproof device 20 and the insect-proof device 30 can be made lighter, and convenient to install and carry; and the aluminum alloy material has high strength and rigidity, and can provide sufficient support and fixing force to ensure the stability and reliability of the dustproof device 20 and the insect-proof device 30 during installation and use; in addition, the aluminum alloy material can be easily processed into various shapes and sizes, so it can meet the needs of dustproof devices 20 and insect-proof devices 30 of different sizes and shapes, thereby achieving the effect of improving the flexibility of the installation of the dustproof device 20 and the insect-proof device 30.
