The energy storage liquid cooling unit cools and heats the battery pack, allowing the battery pack to operate within the optimal comfortable temperature range, improving its life and safety; therefore, it is particularly important for the energy storage liquid cooling unit to prevent backflow and improve refrigeration performance.

[0003] During the operation of the existing energy storage liquid cooling unit, the air entering the condenser is at the ambient temperature.

[0031] See also Figure 1 , Figure 2 The present application provides a liquid cooling unit assembly for preventing backflow of air, comprising a shell 1, a dehumidification component, a fan component and a liquid cooling component.

[0032] The housing 1 is divided into a first chamber 8, a second chamber 9 and a third chamber 10 which are independently arranged from top to bottom.

[0033] The dehumidification component is located in the first chamber 8 and the top of the shell 1.

[0034] The fan assembly is located in the second chamber 9. The second chamber 9 is connected to the third chamber 10 through a guide channel. The shell 1 is provided with an air outlet 13 connected to the second chamber 9. The first baffle 4 and the second baffle 7 for preventing backflow are respectively installed on the upper and lower sides of the air outlet 13.

[0035] The liquid cooling component is located in the third chamber 10 , and the shell 1 is provided with an air inlet 12 which is in communication with the third chamber 10 .

[0036] It should be noted that the components such as the liquid cooling component and the fan component in the liquid cooling unit assembly for preventing backflow provided by the present application are the same as those in the prior art, and the installation method has not been improved. The improvement of the present application is that the first baffle 4 and the second baffle 7 for preventing backflow are respectively installed on the upper and lower sides of the air outlet 13, such as Figure 1 , Figure 2 As shown, the cold air a entering from the air inlet 12 passes through the liquid cooling component and the fan component once, and then becomes hot air b and is discharged from the air outlet 13. For a liquid cooling unit with the air inlet 12 and the air outlet 13 on the same side of the housing 1, if the first baffle 4 and the second baffle 7 are not installed, the hot air b can easily enter the liquid cooling component again from the air inlet 12, thereby affecting the heat dissipation efficiency and the cooling effect.

[0037] Optionally, the air inlet 12 and the air outlet 13 are arranged on the same side of the housing 1 .

[0038] Optionally, an air inlet grille 3 is installed at the air inlet 12 .

[0039] Optionally, the fan assembly includes at least one first fan 2 , which draws the airflow flowing out of the liquid cooling assembly into the second chamber 9 through the guide channel and then discharges it through the air outlet 13 .

[0040] Optionally, the dehumidification assembly includes a second fan 11 and a dehumidification air outlet 5 disposed on the top of the housing 1, the dehumidification air outlet 5 is connected to the first chamber 8, and the direction of the dehumidification air outlet 5 is opposite to the direction of the air outlet 13. The second fan 11 is a dehumidification fan.

[0041] In this embodiment, the dehumidification air outlet 5 is arranged in the opposite direction to the air outlet 13 to prevent the hot outlet air b from moving upward and flowing back from the dehumidification air outlet 5 into the dehumidification component. Since the hot outlet air b has a higher temperature, it will affect the dehumidification effect of the liquid cooling unit assembly after flowing back into the dehumidification component. The dehumidification air outlet 5 is arranged in the opposite direction to the air outlet 13 to ensure that the airflow entering the dehumidification air outlet 5 each time is the airflow at the same ambient temperature as the cold inlet air a.

[0042] Optionally, the housing 1 is provided with an opening (not shown in the figure) facing the same direction as the air outlet 13, the opening is communicated with the first chamber 8, and the first baffle 4 is installed at the opening.

[0043] like Figure 1 , Figure 2 As shown, since the second fan 11 is installed in the first chamber 8, the hot air b has a small density and will move upward. The hot air b will be discharged from the air outlet 13 and will pass through the opening. The first baffle 4 is installed at the opening of the first chamber 8 to prevent the hot air b from flowing back into the first chamber 8 from the opening.

[0044] Optionally, the second baffle 7 is installed between the air inlet 12 and the air outlet 13 .

[0045] like Figure 1 , Figure 2 As shown, since the cold incoming air a has a large density and moves downward, and the hot outlet air b has a small density and moves upward, a second baffle 7 is provided below the air outlet 13 to prevent return air. This can effectively prevent the hot outlet air b from moving downward and flowing back into the liquid cooling component, affecting the heat dissipation efficiency and the cooling effect.

[0046] Optionally, the liquid cooling assembly includes a pipeline and a cooling device installed on the pipeline, the cooling device exchanges heat with the airflow entering through the air inlet 12, and transports the airflow with a higher temperature after heat exchange to the second chamber 9 through the pipeline and the guide channel.

[0047] Optionally, the cooling device includes at least a condenser.

[0048] Optionally, the housing 1 is a square structure.

[0049] A plurality of mounting points 6 for mounting the dehumidification vents 5 are provided on the top of the housing 1 .

[0050] It should be noted that the difference between the liquid cooling unit assembly provided in the present application and the liquid cooling unit in the prior art is that the anti-return air design is adopted, and the other components are all prior art. The liquid cooling component of the liquid cooling unit in the prior art includes a pipeline and a cooling device, and the pipeline includes a refrigeration circuit and a cooling circuit. The cooling circuit can be arranged in the third chamber 10, and the cooling circuit is filled with a cooling medium. The two ends of the cooling circuit are used to communicate with the battery pack. For example, the battery pack can be arranged in an independent chamber, and the cooling circuit is connected to the above-mentioned independent chamber, that is, the battery pack can be immersed in the cooling medium of the cooling circuit to cool the battery pack by water. The cooling device generally includes a compressor, a condenser, a filter, and a heat exchanger. The return air design of the liquid cooling unit assembly adopted in the present application can be applied to any liquid cooling unit with an air inlet 12 and an air outlet 13 on the same side of the housing 1, such as the GWR-BP30BH model liquid cooling unit. The structure of the liquid cooling component, the fan component, etc. of the present application is the same as that of the liquid cooling unit of this model. Therefore, the specific structures of the liquid cooling component, the fan component and the dehumidification component will not be elaborated here.

[0051] In summary, the present application provides a liquid cooling unit assembly for preventing backflow, which has a first baffle 4 and a second baffle 7 for preventing backflow installed on the upper and lower sides of the air outlet 13, respectively, so that the airflow entering the condenser and the dehumidification component is the airflow at the ambient temperature, effectively ensuring the output of the cooling capacity of the liquid cooling unit, so that the battery pack and electrical components are in a comfortable working environment, increasing the service life of the battery pack and electrical components, improving the quality, and having a competitive position in the market.

[0052] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
