At the same time, a waterproof and dustproof design is usually required at the air inlet, and a filter screen and a louver structure are added on the air inlet side. However, the filter screen and the louver structure often affect the air intake volume, resulting in the air intake volume being insufficient to meet the complete heat dissipation requirements of the liquid-cooled energy storage water machine. Summary of the Invention

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0039] When the distributed liquid-cooled energy storage water machine provides thermal management services for the battery PACK, a relatively large amount of heat will be generated. This is because during the operation of the liquid-cooled energy storage water machine, it is necessary to circulate the coolant to absorb and carry away the heat generated by the battery PACK, so as to keep the battery within an appropriate operating temperature range. However, during this process, the components of the water machine itself, such as pumps, heat exchangers, etc., will also generate heat due to operation. Therefore, the heat dissipation of the liquid-cooled water machine is crucial for its operating temperature. If the heat dissipation is poor, the temperature of the water machine will continue to rise, which will not only affect its own working efficiency and stability, but may also have an adverse impact on the battery PACK, and even cause safety problems. In order to ensure the normal operation of the liquid-cooled water machine and extend its service life, while dissipating heat, it is also necessary to ensure the cleanliness inside the liquid-cooled water machine.

[0040] The liquid-cooled water machine usually adopts the natural air-cooled heat dissipation method. At the same time, in order to ensure the waterproof and dustproof performance of the equipment, a filter screen and a louver structure design are added. Under the combined action of these measures, it can be ensured that the liquid-cooled water machine maintains a stable working state while effectively dissipating heat. However, with the addition of the filter screen and the louver structure, the ventilation effect may be affected.

[0041] Based on the above situation, the present application proposes a louver structure, a distributed liquid-cooled energy storage water machine, and an energy storage device. The present application will be described in detail below with reference to embodiments and drawings.

[0042] As an embodiment of a louver structure of the present application, it may include a louver assembly 1. One side of the louver assembly 1 is an air inlet side 2, and the other side is an air outlet side 3. A ventilation channel 4 is formed between the air inlet side 2 and the air outlet side 3. In practical applications, gas enters the ventilation channel 4 from the air inlet side 2, and after passing through the louver assembly 1, it flows out from the air outlet side 3. The ventilation area of the air inlet side 2 of the louver assembly 1 is larger than the ventilation area of the air outlet side 3 of the louver assembly 1. It should be noted that the ventilation area of the air inlet side 2 is large and the ventilation area of the air outlet side 3 is small. Even if there is a problem of insufficient air intake due to the influence of the louver assembly 1 and the filtering device 5, through this structural design, the problem that the subsequent heat dissipation equipment cannot be fully cooled due to insufficient air intake can be solved. In addition, a filtering device 5 is arranged in the ventilation channel 4 of the louver assembly 1, which can filter the gas flowing through the ventilation channel 4 to ensure cleanliness. In practical applications, the specific structural type and specific installation position of the filtering device 5 can be adjusted and determined according to the usage requirements and structural conditions, and the present application does not make specific limitations.

[0043] As Figure 1 and Figure 2 shown, it is another schematic diagram of the louver structure of the present application. Among them, there are seven rows of louvers in the louver assembly 1. In practical applications, the specific scale of the louver assembly 1 can be adjusted according to the usage requirements. For example, when the ventilation area of the air inlet side 2 is large, the number of louvers can be set more. The air inlet side 2 of the louver assembly 1 is set as a sheet metal air duct. The side wall of the part of the sheet metal air duct close to the ground is inclined and the large end is close to the air inlet side 2. Usually, the sizes of the ventilation areas of the air inlet side 2 and the air outlet side 3 of the louver assembly 1 are designed to be the same. The louver structure that can increase the air intake proposed by the present application realizes sufficient air intake and waterproof and dustproof requirements by increasing the ventilation area, filter screen size, and the number of louvers of the air inlet side 2 of the louver assembly 1. At the same time, the ventilation area of the air outlet side 3 of the louver assembly 1 is reduced so that it can be closely matched with the subsequent equipment, thereby realizing that sufficient air volume enters the louver assembly 1 through the air inlet side 2 of the louver assembly 1, passes through the louvers and the filtering device 5, and then enters the subsequent equipment from the air outlet side 3 of the louver assembly 1, realizing natural air cooling and heat dissipation of the subsequent equipment.

[0044] In order to reduce the ventilation area of the air outlet side 3 of the louver assembly 1, there are many implementation methods, such as Figure 2As an implementation, the sheet metal air duct extends to the air outlet side 3 of the louver assembly 1. The extending direction of the baffle 6 is perpendicular to the axial direction of the ventilation channel 4, and the baffle 6 is connected to the sheet metal air duct and extends into the ventilation channel 4. By providing the baffle 6, the ventilation area of the air outlet side 3 is reduced. In other embodiments of the present application, it can also be implemented by other structural forms, and the present application does not make specific limitations.

[0045] Based on the above louver structure, as Figure 3 shown, the present application also proposes a distributed liquid-cooled energy storage water machine, which may include a liquid-cooled water machine body 7 and the louver structure described above. The air outlet side 3 of the louver assembly 1 is hermetically connected to the air inlet 10 of the liquid-cooled water machine body 7. In practical applications, for the specific structural form of the hermetic connection, any existing connection method can be adopted as long as the hermetic connection can be ensured. For example, a sealing strip 12 can be used to achieve the hermetic connection.

[0046] It should be noted that the louver structure of the present application can be applied to various liquid-cooled water machine bodies 7, and the specific structure of the liquid-cooled water machine body 7 is not limited. For example, the liquid-cooled water machine body 7 may include a water machine body 8 and a water machine cooling exhaust fan 9. The two ends of the water machine body 8 are respectively provided with an air inlet 10 and an air outlet 11, and the water machine cooling exhaust fan 9 is located on one side of the air outlet 11. In this embodiment, the sealing is achieved through the sealing strip 12, and the sealing strip 12 is installed between the air outlet side 3 of the louver assembly 1 and the air inlet 10 of the liquid-cooled water machine body 7.

[0047] In practical applications, the louver structure is installed at the corresponding position of the air inlet 10 of the water machine body 8. The air flow direction during the operation of the water machine body 8 is the flow direction from left to right ( Figure 3 shown by the arrow in), that is, the outside air enters the louver assembly 1 from the air inlet side 2, and then passes through the waterproof louvers and the filtering device 5 (which can be a dust filter) and enters the water machine body 8 through the air outlet side 3, and finally is sucked into the water machine body 8 by the cooling fan in the water machine body 8, and the heat in the water machine body 8 is discharged from the air outlet 11 on the right side of the water machine body 8, so as to achieve the heat dissipation during the operation of the water machine body 8.

[0048] Similarly based on the distributed liquid-cooled energy storage water machine, as Figure 4 shown, the present application also proposes an energy storage device, which may include an energy storage device body 13 and the aforementioned distributed liquid-cooled energy storage water machine, and the distributed liquid-cooled energy storage water machine is installed at the bottom of the energy storage device body 13.

[0049] The distributed liquid-cooled energy storage water machine is installed at the bottom of the energy storage device body 13. A louver structure is installed between the distributed liquid-cooled energy storage water machine and the air inlet 10 of the corresponding energy storage device cabinet. The dust prevention of the device is achieved through the filtering device 5, and the waterproofing is achieved by making the bottom of the louver and the duct sheet metal inclined for drainage. During the operation of the distributed liquid-cooled energy storage water machine, the cooling exhaust fan 9 of the water machine continuously sucks in air from the outside, enters the interior of the distributed liquid-cooled energy storage water machine through the air outlet side 3 of the louver assembly 1. The low-temperature air outside exchanges heat with the hot air inside the distributed liquid-cooled energy storage water machine, and the heat is continuously taken away by the cooling exhaust fan of the water machine to achieve the heat dissipation and cooling of the distributed liquid-cooled energy storage water machine, ensuring the continuous normal operation of the distributed liquid-cooled energy storage water machine.

[0050] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
