[0003] Currently, the heat dissipation effect of some existing micro photovoltaic energy storage inverters is not ideal. They cannot adaptively dissipate heat and cool down according to environmental needs, which leads to an increase in internal temperature, increasing the risk of use and reducing their service life. Summary of the Invention

Cooling fins are uniformly fixedly connected to the other side of the semiconductor cooling chip. The interior of the cooling chamber is provided with cooling fins fixedly connected to... The baffle, the semiconductor cooling chip, the cooling fins, and the baffle form an air duct with openings at both ends. Air outlets connected to the drying chamber are evenly distributed at the top of one side of the cooling chamber, and these outlets are located at the top of the mounting plate. A fan is installed inside each air outlet. A desiccant is placed inside the drying chamber. An air outlet is located on one side of the outer shell, at the bottom of the mounting plate and on one side of the cooling chamber. A dustproof mechanism for sealing and preventing dust is provided on one side of the air outlet. The system automatically adjusts its cooling according to different temperatures.

[0008] Preferably, a first filter screen is fixedly connected to one end of the air inlet, and an anti-clogging groove is provided on one side of the outer shell. The first filter screen is located inside the anti-clogging groove to prevent external impurities and dust from entering the device and to prevent the first filter screen from being clogged. The connection between the cooling chamber and the drying chamber is a wide-mouth shape with a larger bottom and a smaller top, which facilitates the placement of desiccant.

[0009] Preferably, the control terminals of the semiconductor cooling chip and the fan are both electrically connected to the energy storage battery via temperature detection sensors.

[0010] Preferably, the dustproof mechanism includes a sealing block, one end of which is uniformly provided with a sealed air duct, and the inner wall of one side of the sealed air duct is provided with a groove. One end of the groove is fixedly connected to a fixing rod. Inside the sealed air duct, a sealing plate is provided that is rotatably connected to the fixing rod. One end of the sealing plate is provided with a torsion spring, and both ends of the torsion spring are fixedly connected to the sealing plate and the fixing rod, respectively. The torsion spring is sleeved on the surface of the fixing rod to improve the sealing performance of the device and prevent impurities and dust from entering the device.

[0011] Preferably, a second filter screen is fixedly connected to one end of the air outlet, and one end of the sealing plate is beveled to improve the sealing performance between the sealing plate and the sealed air duct.

[0012] Preferably, the protective mechanism includes airbags. The energy storage chamber contains four sets of airbags that fit snugly against the periphery of the energy storage battery. Each airbag has a fixed support plate on one side. One end of each support plate is connected to a pressure plate via a pivot, and one end of the pressure plate is connected to the inner wall of the outer shell via a pivot. Both the inner wall of the outer shell and one end of the support plate are connected to hinge seats via pivots. Two sets of sleeves are fixedly connected to one end of each hinge seat. A movable rod is slidably connected to one end of each sleeve. An energy-absorbing spring, fixedly connected to the inner wall of the sleeve, is fixedly connected to one end of each movable rod. Two sets of rotating rods are connected to the middle of the pressure plate via bearings. One end of each movable rod is fixedly connected to the rotating rod, thus protecting the energy storage battery and improving its service life.

[0013] Preferably, the airbag is made of an elastic material to improve energy absorption.

[0014] Preferably, the hinge seat, sleeve, movable rod, and pressure plate are arranged in a triangular elastic structure with the rotating rod as the vertex, which reduces space while improving energy absorption and load-bearing capacity, and avoids concentrated stress on a single component in traditional protective structures.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The outer casing is divided into a high-temperature zone and a low-temperature zone by a vacuum partition and a heat-insulating and flame-retardant plate. The area containing the photovoltaic inverter assembly is the high-temperature zone, and the area containing the energy storage battery is the low-temperature zone. The vacuum partition and the heat-insulating and flame-retardant plate can prevent heat transfer between the high-temperature zone and the low-temperature zone. At the same time, the coating on the surface of the heat-insulating and flame-retardant plate can further prevent heat transfer and prevent heat transfer through thermal radiation. If the energy storage compartment or inverter compartment spontaneously combusts, the vacuum partition and the heat-insulating and flame-retardant plate can prevent the fire from spreading to another area, thereby protecting that area and reducing the user's losses.

[0017] The temperature of the high-temperature zone can be detected in real time by a temperature sensor at one end of the mounting plate. When the temperature of the high-temperature zone inside the device is low, cooling is achieved only by natural air drawn in by the fan. The outside air is filtered through the first filter to prevent external impurities and dust from entering the device and contaminating the photovoltaic inverter assembly, which would further affect the heat dissipation of the photovoltaic inverter assembly. The outside air enters the cooling fins and the interior of the cooling chamber and drying chamber through the air inlet, is dried by the desiccant, and is finally blown onto the surface of the photovoltaic inverter assembly by the fan, thereby cooling the photovoltaic inverter assembly. The heated air moves downward through the air trough, and the temperature of the air can be detected by the temperature sensor. The hot air is discharged from the device through the sealing block and the air outlet, achieving low-power cooling.

[0018] When hot air passes through the sealing block, it blows the sealing plate in the middle of the sealed air duct. At this time, the sealing plate makes a circular motion and compresses the torsion spring. When the fan stops working, the sealing plate closes the sealed air duct under the action of the torsion spring, which can prevent external dust from entering the device and prevent dust from adhering to the surface of the photovoltaic inverter assembly and affecting its heat dissipation.

[0019] When the temperature sensor detects that the temperature inside the inverter chamber exceeds the set temperature, the thermoelectric cooler operates. The side of the thermoelectric cooler with the cooling fins generates a low temperature, which cools the air entering the cooling chamber. The cold air is then dried by a desiccant and blown onto the surface of the photovoltaic inverter assembly by a fan, thereby improving heat dissipation efficiency, ensuring that the photovoltaic inverter assembly is at its normal operating temperature, and improving its safety during use.

[0020] If this device is impacted or dropped, the energy storage battery will first be cushioned by the airbag, which will protect it from the impact. If the impact force is large, the airbag may not be sufficient to protect the energy storage battery. In this case, the airbag, together with the receiving plate, pressure plate, movable rod, energy-absorbing spring and hinge seat, will absorb energy a second time to prevent the energy storage battery from being impacted and further protect it, thereby improving the safety of the energy storage battery.

[0021] This device can adaptively cool down to ensure it operates at a safe temperature, prevent external dust from entering and reducing heat dissipation efficiency, provide zoned protection to improve safety and reduce user losses, and protect the energy storage battery from impacts, thus enhancing its safety.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-8 One embodiment provided by the present invention:

[0026] A high-efficiency heat dissipation micro photovoltaic energy storage inverter includes a shell 1. A vacuum partition 3 is fixedly connected inside the shell 1, dividing the shell 1 into two cavities. The upper and lower cavities of the vacuum partition 3 are respectively the inverter chamber 6 and the energy storage chamber 5. An energy storage battery 31 is installed inside the bottom of the shell 1. Heat-insulating and flame-retardant plates 4 are fixedly connected to both the upper and lower cavities of the vacuum partition 3. An installation plate 7 is fixedly connected to the middle of the inverter chamber 6. An air groove 8 is opened at one end of the installation plate 7. A temperature detection sensor 10 located at the top of the air groove 8 is installed at one end of the installation plate 7. A photovoltaic inverter assembly 9 is installed at the top of the installation plate 7. A cooling mechanism for automatic heat dissipation control is provided at one end of the inverter chamber 6. A protective mechanism for protecting the energy storage battery 31 is provided inside the energy storage chamber 5.

[0027] Please see Figures 2-6In this embodiment, the cooling mechanism includes a cooling box 11. The cooling box 11 is fixedly connected to the inner wall of one end of the inverter chamber 6. A wide-mouth air inlet 12 is opened at one end of the outer shell 1. A cooling chamber 18 is opened at the bottom of the cooling box 11. A drying chamber 19 connected to the cooling chamber 18 is opened at the top of the cooling box 11. A semiconductor cooling chip 15 is installed on the inner wall of one end of the cooling chamber 18, and one side of the semiconductor cooling chip 15 is located outside the outer shell 1. Cooling fins 16 are uniformly fixedly connected to the other side of the semiconductor cooling chip 15. A baffle 17 fixedly connected to the cooling fins 16 is provided inside the cooling chamber 18. The semiconductor cooling chip 15, the cooling fins 16 and the baffle 17 constitute an air duct with openings at both ends. The top of one side of the cooling box 11 is uniformly opened... An air outlet 20 is provided, connected to the drying chamber 19, and located at the top of the mounting plate 7. A fan 21 is installed inside the air outlet 20. A desiccant 22 is provided inside the drying chamber 19. An air outlet 23 is provided on one side of the outer shell 1, located at the bottom of the mounting plate 7 and on one side of the cooling box 11. A dustproof mechanism for sealing and preventing dust is provided on one side of the air outlet 23, which automatically achieves adaptive cooling according to different temperatures. The dustproof mechanism includes a sealing block 25, with a sealed air duct 26 evenly distributed at one end of the sealing block 25. A groove 27 is provided on the inner wall of one side of the sealed air duct 26, and a fixing rod 29 is fixedly connected to one end of the groove 27. A sealing plate 28 is provided inside the sealed air duct 26 and rotatably connected to the fixing rod 29. One end of the 8 is provided with a torsion spring 30, and the two ends of the torsion spring 30 are fixedly connected to the sealing plate 28 and the fixing rod 29 respectively. The torsion spring 30 is sleeved on the surface of the fixing rod 29. When the temperature of the high-temperature zone inside the device is low, cooling is achieved only by the natural air drawn in by the fan 21. The outside air is filtered through the first filter screen 13 to prevent external impurities and dust from entering the device and contaminating the photovoltaic inverter assembly 9, thereby further affecting the heat dissipation of the photovoltaic inverter assembly 9. The outside air enters the interior of the cooling chamber 18 through the air inlet 12, and then moves upward into the interior of the drying chamber 19, where it is dried by the desiccant 22. Finally, the fan 21 blows the air onto the surface of the photovoltaic inverter assembly 9, thereby cooling the photovoltaic inverter assembly 9. The assembly 9 is cooled down, and the heated air moves downward through the air trough 8. The temperature of the air can be detected by the temperature detection sensor 10. The hot air is discharged from the device through the sealing block 25 and the air outlet 23, achieving low-power cooling. When the hot air passes through the sealing block 25, the sealing plate 28 in the middle of the sealed air duct 26 can be blown by the wind force. At this time, the sealing plate 28 performs a circular motion and compresses the torsion spring 30. The hot air is discharged from the device through the sealed air duct 26. When the fan 21 stops working, the sealing plate 28 closes the sealed air duct 26 under the action of the torsion spring 30, which can prevent external dust from entering the device and prevent dust from adhering to the surface of the photovoltaic inverter assembly 9 and affecting its heat dissipation.When the temperature sensor 10 detects that the temperature inside the inverter chamber 6 of the outer casing 1 exceeds the set temperature, the semiconductor cooling chip 15 is activated. The side of the semiconductor cooling chip 15 with the cooling fins 16 fixed thereon generates a low temperature, which cools the air entering the cooling chamber 18, turning it into cold air. After being dried by the desiccant 22, the cold air becomes dry cold air and is blown onto the surface of the photovoltaic inverter assembly 9 by the fan 21, thereby improving heat dissipation efficiency, ensuring that the photovoltaic inverter assembly 9 is at a normal operating temperature, improving its safety in use, improving the sealing of the device, and preventing impurities and dust from entering the device.

[0028] Please see Figure 2 , Figure 7 and Figure 8 In this embodiment, the protective mechanism includes airbags 32. Four sets of airbags 32 are installed inside the energy storage chamber 5, each fitting against the periphery of the energy storage battery 31. A receiving plate 33 is fixedly connected to one side of each airbag 32. One end of the receiving plate 33 is connected to a pressure plate 34 via a pivot, and one end of the pressure plate 34 is connected to the inner wall of the outer shell 1 via a pivot. Both the inner wall of the outer shell 1 and one end of the receiving plate 33 are connected to a hinge seat 35 via a pivot. Two sets of sleeves 36 are fixedly connected to one end of the hinge seat 35. One end of the sleeve 36 is slidably connected to a movable rod 37, and one end of the movable rod 37 is fixedly connected to an energy-absorbing spring 38 that is fixedly connected to the inner wall of the sleeve 36. Two sets of rotating rods 39 are connected to the middle of the pressure plate 34 via bearings. One end of the movable rod 37 is fixedly connected to the rotating rod 39 to protect the energy storage battery 31 and improve its service life. The hinge seat 35, sleeve 36, movable rod 37, and pressure plate 34 form a triangular elastic structure with the rotating rod 39 as the vertex, reducing space requirements. At the same time, it improves the energy absorption effect and load-bearing capacity, and avoids the concentrated force on a single component in the traditional protective structure. If the device is impacted or dropped, the energy storage battery 31 is first buffered by the airbag 32. The airbag 32 protects the energy storage battery 31 from collision. If the impact force on the device is large, the airbag 32 cannot meet the protection requirements of the energy storage battery 31. At this time, the airbag 32 pushes the receiving plate 33 to move towards the inner wall of the outer shell 1. As the distance between the receiving plate 33 and the inner wall of the outer shell 1 is shortened, the pressure plate 34 also makes a circular motion. At this time, the distance between the rotating rod 39 and the receiving plate 33 and the inner wall of the outer shell 1 is shortened. Therefore, the movable rod 37 will move towards the inside of the sleeve 36, thereby compressing the energy absorption spring 38. The energy absorption spring 38 absorbs energy again, preventing the energy storage battery 31 from being impacted and further protecting the energy storage battery 31, thereby improving the safety of the energy storage battery 31.

[0029] It should be noted that the top of the outer shell 1 is connected to a handle 2 via a pivot, which facilitates the user's movement of the device. A control panel is provided at one end of the outer shell 1, and four sets of pads are fixedly connected to the bottom of the outer shell 1. The heat insulation and flame retardant plate 4 is made of ceramic fiber material, which improves the heat insulation and flame retardant effect. The surfaces of the vacuum partition 3 and the heat insulation and flame retardant plate 4 are coated with an aluminum oxide coating to avoid heat radiation. A first filter screen 13 is fixedly connected to one end of the air inlet 12. An anti-clogging groove 14 is provided on one side of the outer shell 1. The first filter screen 13 is located inside the anti-clogging groove 14 to prevent external impurities and dust from entering the device and to prevent the first filter screen 13 from being blocked. The connection between the cooling chamber 18 and the drying chamber 19 is a wide-mouth shape with a larger bottom and a smaller top, which facilitates the placement of the desiccant 22. The control terminals of the semiconductor cooling chip 15 and the fan 21 are both electrically connected to the energy storage battery 31 through the temperature detection sensor 10. A second filter screen 24 is fixedly connected to one end of the air outlet 23. One end of the sealing plate 28 is beveled to improve the sealing between the sealing plate 28 and the sealed air duct 26. The airbag 32 is made of elastic material to improve the energy absorption effect.

[0030] Working Principle: The outer casing 1 is divided into a high-temperature zone and a low-temperature zone by a vacuum partition 3 and a heat-insulating and flame-retardant plate 4. The area containing the photovoltaic inverter assembly 9 is the high-temperature zone, and the area containing the energy storage battery 31 is the low-temperature zone. The vacuum partition 3 and the heat-insulating and flame-retardant plate 4 prevent heat transfer between the high-temperature zone and the low-temperature zone. Furthermore, the coating on the surface of the heat-insulating and flame-retardant plate 4 further prevents heat transfer through radiation. If the energy storage compartment 5 or the inverter compartment 6 spontaneously combusts, the vacuum partition 3 and the heat-insulating and flame-retardant plate 4 prevent the fire from spreading to another area, thus protecting that area and reducing user losses. The temperature sensor 10 at one end of the mounting plate 7 can detect the temperature of the high-temperature zone in real time. When the temperature of the high-temperature zone inside the device is low, cooling is achieved solely by natural air drawn in by the fan 21. Outside air is filtered through the first filter 13 to prevent impurities and dust from entering the device and contaminating the photovoltaic inverter assembly 9, which would further affect its heat dissipation. Outside air enters the cooling chamber 18 through the air inlet 12, then moves upwards into the drying chamber 19, where it is dried by the desiccant 22. Finally, the fan 21 blows the air onto the surface of the photovoltaic inverter assembly 9, thus cooling the photovoltaic inverter assembly. Cooling is achieved by the fan 9. The heated air moves downward through the air trough 8. The temperature of the air can be detected by the temperature sensor 10. The hot air is discharged from the device through the sealing block 25 and the air outlet 23, achieving low-power cooling. When the hot air passes through the sealing block 25, the airflow can blow the sealing plate 28 in the middle of the sealed air duct 26. At this time, the sealing plate 28 performs a circular motion, and the rotating sealing plate 28 compresses the torsion spring 30. The hot air is then discharged from the device through the sealed air duct 26. When the fan 21 stops working, the sealing plate 28 closes the sealed air duct 26 under the action of the torsion spring 30, which can prevent external airflow. Dust enters the device to prevent it from adhering to the surface of the photovoltaic inverter assembly 9 and affecting its heat dissipation. When the temperature detection sensor 10 detects that the temperature inside the inverter chamber 6 of the outer casing 1 exceeds the set temperature, the semiconductor cooling chip 15 is activated. The side of the semiconductor cooling chip 15 with the cooling fins 16 fixed generates a low temperature, which can cool the air entering the cooling chamber 18, making it cold air. After being dried by the desiccant 22, the cold air becomes dry cold air, which is then blown onto the surface of the photovoltaic inverter assembly 9 by the fan 21, thereby improving the heat dissipation efficiency, ensuring that the photovoltaic inverter assembly 9 is at the normal operating temperature, and improving its safety in use.If the device is impacted or dropped, the energy storage battery 31 is first cushioned by the airbag 32, which protects it from impact. If the impact force is large, the airbag 32 may not be sufficient to protect the energy storage battery 31. In this case, the airbag 32 pushes the receiving plate 33 towards the inner wall of the outer shell 1. As the distance between the receiving plate 33 and the inner wall of the outer shell 1 decreases, the pressure plate 34 also moves in a circular motion. At this time, the distance between the rotating rod 39 and both the receiving plate 33 and the inner wall of the outer shell 1 decreases, so the movable rod 37 will move towards the inside of the sleeve 36. The device moves to compress the energy-absorbing spring 38, allowing for secondary energy absorption and preventing the energy storage battery 31 from being impacted, thus further protecting the battery and improving its safety. The device also adaptively cools to ensure a safe operating temperature, preventing dust from entering and reducing heat dissipation efficiency. Furthermore, it provides zoned protection, enhancing safety and reducing user losses. Finally, it protects the energy storage battery 31 from impacts, further improving its safety.
