[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] See also Figures 1 to 5 In the utility model: a heat dissipation structure of an energy storage inverter comprises a body 1, an air outlet groove 2 and an air inlet groove 3 are respectively provided on the left and right sides of the body 1, a rotating cylinder 4 is rotatably connected to the inner wall of the air inlet groove 3, a motor 5 is embedded on the right side of the body 1, the output shaft of the motor 5 passes through the body 1 and is fixedly connected to the rotating cylinder 4, a fan 6 is installed on the inner wall of the rotating cylinder 4, two through grooves 7 are provided on the inner wall of the rotating cylinder 4, an air inlet duct 8 and an exhaust duct 9 are provided on the inner wall of the air inlet groove 3, and a filter screen 10 is fixedly connected to the inner wall of the through groove 7 on the right side.

[0027] In the utility model, when in use, the fan 6 is turned on, and the fan 6 will suck the air outside the body 1 into the body 1 through the two through slots 7. The air will then flow inside the body 1 and be discharged from the air outlet slot 2. During the air flow, the electrical equipment inside the body 1 will be cooled, thereby achieving the heat dissipation effect. During the air flow, the filter 10 located in the through slot 7 can achieve the effect of filtering dust in the air, thereby preventing dust from entering the body 1 and contaminating the electrical equipment. After long-term use, when a large amount of dust adheres to the surface of the filter 10, the user first turns on the motor 5, and the motor 5 drives the rotating drum 4 is rotated 90 degrees, at which time the two through slots 7 will be aligned with the air inlet duct 8 and the exhaust duct 9 respectively, and the user will turn on the fan 6 in the reverse direction, and the fan 6 will suck the air from the air inlet duct 8 into the inside of the rotating cylinder 4, and the air will pass through the filter 10 in the reverse direction and be discharged from the exhaust duct 9. As the air passes through the filter 10 in the reverse direction, the air can achieve the effect of recoil cleaning of the filter 10, and then blow off the dust attached to the surface of the filter 10. After the filter 10 is cleaned, the user turns on the motor 5 in the reverse direction until the motor 5 drives the rotating cylinder 4 to reset, and then turns on the fan 6 in the forward direction to continue to dissipate heat for the electrical equipment inside the body 1.

[0028] See also Figures 2 to 4, wherein: a filter box 11 is inserted into the right side of the body 1 and is slidably connected thereto, the outer side of the filter box 11 contacts the inner wall of the exhaust duct 9, a screw rod 12 is inserted into the right side of the filter box 11 and is rotatably connected thereto, and the left end of the screw rod 12 is inserted into the body 1 and is threadedly connected thereto.

[0029] In the utility model, the filter box 11 can be locked by the screw 12, and the filter box 11 can collect the dust blown off from the filter screen 10, thereby avoiding the secondary pollution of dust and improving the environmental protection ability of the device.

[0030] See also Figure 5 , wherein: two slide grooves 13 are opened on the inner wall of the exhaust duct 9, the inner walls of the two slide grooves 13 are slidably connected with sliders 14, the bottoms of the two sliders 14 are fixedly connected with springs 15, the other ends of the two springs 15 are respectively fixedly connected to the inner walls of the two slide grooves 13, the tops of the two sliders 14 are fixedly connected with cleaning brushes 16, and the tops of the two cleaning brushes 16 are in contact with the rotating cylinder 4.

[0031] In the present invention, the elastic force of the spring 15 can drive the slider 14 to rise along the slide groove 13, so that the cleaning brush 16 is in close contact with the rotating drum 4. After the rotating drum 4 rotates, the cleaning brush 16 will slide into the surface of the filter 10. The user can drive the motor 5 left and right to make the rotating drum 4 rotate forward and reversely. The cleaning brush 16 will continuously slide along the surface of the filter 10, thereby achieving the effect of cleaning the surface of the filter 10 and improving the ability to clean the filter 10.

[0032] See also Figures 1 to 4 , wherein: the inner wall of the air inlet 8 and the inner wall of the air outlet groove 2 are fixedly connected with a filter plate 17, and a controller 18 is installed on the front of the body 1.

[0033] In the utility model, the setting of the filter plate 17 can prevent dust from polluting the inside of the device through the air outlet groove 2 and the air inlet duct 8, thereby improving the practicality of the device. The setting of the controller 18 can facilitate the user to control the motor 5 and the fan 6, thereby improving the practicality of the device.

[0034] See also Figure 3 , wherein: a flow rate sensor 19 is installed on the inner wall of the air outlet groove 2, and the output end of the flow rate sensor 19 is connected to the controller 18 for signal.

[0035] In the utility model, the flow rate sensor 19 can detect the flow rate of air discharged from the air outlet groove 2. If the filter 10 is attached with a large amount of dust, the detected data will become smaller. By observing the data, it can be determined whether the filter 10 needs to be cleaned, and then the filter 10 can be cleaned at the first time to maintain the heat dissipation effect on the electrical equipment in the main body 1.

[0036] The above are only preferred specific implementations of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
