Description

Technical Field

[0001] This utility model relates to the field of energy storage equipment technology, and in particular to a low-voltage DC inverter compressor refrigeration dehumidifier for the energy storage industry. Background Technology

[0002] In recent years, with the development of wind and solar power, the demand for power auxiliary services such as peak shaving, frequency regulation, and power output smoothing has increased significantly, leading to the rapid development of energy storage technology and the growing popularity of energy storage devices. The main internal operating component of energy storage devices is the battery module. These components generate heat during operation. If this heat cannot be dissipated in time, it will accumulate, damaging the battery module and other electrical components, and severely impacting the lifespan of the energy storage container.

[0003] A search revealed Chinese patent publication number CN220544021U, which discloses an energy storage container, including an energy storage container body, a ventilation and heat dissipation mechanism located inside the energy storage container body, and a support mechanism located outside the energy storage container body. The ventilation and heat dissipation mechanism includes a ventilation duct located above the interior of the energy storage container body. A dust filter is installed on one side of the ventilation duct, and an exhaust fan is installed on the other side of the dust filter. A first dehumidifying filter element is installed on the other side of the exhaust fan, and a second dehumidifying filter element is provided on one side of the first dehumidifying filter element. The support mechanism includes a mounting block.

[0004] This patent improves upon existing energy storage containers by incorporating a ventilation and heat dissipation mechanism. This mechanism addresses the issue of heat generation during operation, which can lead to excessive heat accumulation and increased internal temperature. Overly high temperatures can negatively impact the performance and lifespan of batteries and electrical equipment used for energy conversion. Furthermore, during the filtration process, dust and other particulate matter accumulate on the surface of the dust filter, affecting airflow and reducing heat dissipation. Utility Model Content

[0028] Example 1

[0029] A low-voltage DC inverter compressor refrigeration dehumidifier for the energy storage industry, such as Figures 1 to 4 As shown, the system includes an air intake assembly 1, one end of which is connected to a refrigerated dehumidification chamber 2, and the other end of which is connected to an air guide duct 3. An air outlet 4 is located at the top of the air guide duct 3. The air intake assembly 1 includes an air intake pipe 11 and a filter plate 12. The filter plate 12 is detachably fixed to the inner wall of the air intake pipe 11. A water spray pipe 13 is fixed to the top inner wall of the air intake pipe 11, and the bottom of the water spray pipe 13 has multiple nozzles facing the filter plate 12. A water outlet groove is located at the bottom of the air intake pipe 11 on one side of the filter plate 12. An air compressor 14 is installed on the top inner wall of the refrigerated dehumidification chamber 2. The air intake end of the air compressor 14 is connected to the air intake pipe 11, and the air outlet end of the air compressor 14 is connected to an evaporator 15. A water outlet is connected to a water collection tank 20, in which a water level sensor is installed. A condenser 16, a liquid receiver 17, a liquid separator 18, and a compressor 19 are installed on one side of the evaporator 15. A pipe leading out of the compressor 19 passes through the interior of the condenser 16 to the liquid receiver 17. A ball valve 21 is installed on the pipe between the compressor 19 and the condenser 16. A pipe leading out of the liquid receiver 17 passes through the interior of the evaporator 15 to the liquid separator 18. A dryer filter 22 and an expansion valve 23 are installed sequentially on the pipe between the liquid receiver 17 and the evaporator 15. The liquid separator 18 is connected to the compressor 19. The air outlet of the evaporator 15 is connected to the air guide duct 3. One end of the water spray pipe 13 is connected to the water collection tank 20 via a water pump.

[0030] During heat dissipation, the air compressor 14 draws outside air into the evaporator 15 through the intake pipe 11. The compressed air is compressed and cooled in the evaporator 15, and the moisture in the air condenses and enters the water collection tank 20. The air that has been condensed and dehumidified enters the air guide 3 and then flows out from the air outlet 4 for heat dissipation. At the same time, the low-temperature liquid refrigerant evaporates into a gaseous state and enters the compressor 19, where it is compressed into a high-temperature and high-pressure refrigerant gas. The gas flows through the condenser 16, and the ball valve 21 controls the gas input in this process. After the gas condenses into low-temperature liquid refrigerant, it enters the liquid receiver 17 and then flows through the dryer filter 22 into the expansion valve 23. The expansion valve 23 reduces the pressure and temperature of the low-temperature liquid refrigerant. The expanded low-temperature liquid refrigerant enters the evaporator 15, where it exchanges heat with the compressed air inside the evaporator 15 and is evaporated into a gaseous state. It then enters the liquid separator 18 to separate a small amount of incompletely evaporated liquid refrigerant. The liquid separator 18 then sends the gaseous refrigerant back to the compressor 19 for a new round of refrigeration cycle. As air flows through the intake pipe 11, the filter plate 12 filters the air to remove particulate matter. After the device has been working for a period of time or when the water level in the water tank 20 is too high, the water pump sends the water from the water tank 20 to the spray pipe 13 and sprays it onto the surface of the filter plate 12 to rinse the surface of the filter plate 12. The rinsing water flows out from the outlet tank.

[0031] By installing a water spray pipe 13, the condensate generated by condensation dehumidification can be used to rinse the surface of the filter plate 12 and clean the particles attached to the surface of the filter plate 12.

[0032] Example 2

[0033] A low-voltage DC inverter compressor refrigeration dehumidifier for the energy storage industry, this embodiment is based on embodiment 1, with the following improvements, such as... Figures 5 to 6 As shown, multiple guide vanes 5 are arranged in a straight line on the inner wall of the air duct 3 at the air outlet 4. The guide vanes 5 are rotatably connected to the air duct 3. A sliding rod 7 is slidably connected to the inner wall of the air duct 3. A telescopic rod 6 is rotatably connected to the top of the sliding rod 7. The telescopic end of the telescopic rod 6 is connected to the guide vane 5. A housing 10 is fixedly connected to the inner wall of the air duct 3. An impeller 9 is rotatably connected to the inner wall of the housing 10. A turntable 8 is connected to one end of the shaft of the impeller 9. A rectangular sliding ring 25 is fixedly connected to one end of the sliding rod 7. A protruding rod 24 that slides with the inner wall of the rectangular sliding ring 25 is fixed to the outer wall of the turntable 8.

[0034] When the air flows along the air guide channel 3 after being condensed and dehumidified, the air impacts the impeller blades on the surface of the impeller 9, causing the impeller 9 to rotate. This rotates the turntable 8, which in turn drives the sliding rod 7 to move laterally back and forth through the convex rod 24 and the rectangular sliding ring 25. The sliding rod 7 drives the telescopic rod 6 to move, and the telescopic rod 6 drives the guide vane 5 to swing. The guide vane 5 guides the airflow from the outlet 4, making the airflow diffusion range larger.

[0035] By setting guide vanes 5, the airflow flowing out from the air outlet 4 can be guided, so that the airflow diffusion range is larger and the dead angle of heat dissipation airflow diffusion is reduced.

[0036] By incorporating a sliding rod 7, a turntable 8, an impeller 9, and a housing 10, the impeller 9 is driven to rotate by the airflow flowing in the air guide 3, which in turn drives the guide vane 5 to oscillate. By using airflow as a power source, the number of power sources required is reduced.

[0037] Working principle: During heat dissipation, the air compressor 14 draws outside air into the evaporator 15 through the intake pipe 11. The compressed air is compressed and cooled in the evaporator 15, and the moisture in the air condenses and enters the water collection tank 20. The air that has been condensed and dehumidified enters the air guide duct 3 and then flows out from the air outlet 4 for heat dissipation. At the same time, the low-temperature liquid refrigerant evaporates into a gaseous state and enters the compressor 19, where it is compressed into a high-temperature and high-pressure refrigerant gas. The gas flows through the condenser 16, and the ball valve 21 controls the gas input in this process. After the gas condenses into low-temperature liquid refrigerant, it enters the liquid receiver 17, then flows through the dryer filter 22 and enters the expansion valve 23. The expansion valve 23 reduces the pressure and temperature of the liquid refrigerant. The expanded refrigerant enters the evaporator 15, where it exchanges heat with the compressed air inside the evaporator 15 and is evaporated into a gas. It then enters the liquid separator 18 to separate a small amount of incompletely evaporated liquid. The refrigerant liquid separator 18 delivers the gaseous refrigerant back to the compressor 19 for a new refrigeration cycle. When the air flows along the air guide 3 after being condensed and dehumidified, the air impacts the impeller 9's surface blades, causing the impeller 9 to rotate and drive the turntable 8 to rotate. Through the convex rod 24 and the rectangular sliding ring 25, the sliding rod 7 moves laterally back and forth. The sliding rod 7 drives the telescopic rod 6 to move, and the telescopic rod 6 drives the guide vane 5 to swing. The guide vane 5 guides the airflow from the outlet 4, making the airflow diffusion range larger. When the air flows through the inlet pipe 11, the filter plate 12 filters the air, removing particulate matter mixed in with the air. When the device has been working for a period of time or the water level in the water tank 20 is too high, the water pump delivers the water in the water tank 20 to the spray pipe 13, spraying it onto the surface of the filter plate 12 to rinse the surface of the filter plate 12. The rinsing water flows out from the outlet tank.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
