[0031] Liquid-cooled energy storage equipment is a device that can store energy and release it when needed. It can be used in renewable energy systems such as solar energy and wind energy. Liquid-cooled energy storage equipment usually uses coolant circulation to absorb and release heat to achieve energy storage and release. As the core component of liquid-cooled energy storage equipment, the heat dissipation performance of the liquid cooling unit directly affects the charging and discharging efficiency and service life of the energy storage equipment. At present, the air inlet, the unit itself, and the air outlet of the liquid cooling unit form an air duct. The external air enters the liquid cooling unit through the air inlet, exchanges heat with the unit, and is discharged to the outside of the cabinet through the exhaust port. However, after the hot air comes out of the exhaust port, it overflows and is very easy to flow back to the air inlet and enter the liquid cooling unit again, affecting the heat dissipation performance of the unit.

[0032] The present application provides a liquid cooling unit, Figure 1is a side view structural diagram of a liquid cooling unit in an exemplary embodiment of the present application, Figure 2 is a schematic diagram of the three-dimensional structure of a liquid cooling unit in an exemplary embodiment of the present application. Figure 3 is a partially enlarged structural schematic diagram of a liquid cooling unit in an exemplary embodiment of the present application, Figure 4 is a partial enlarged structural schematic diagram of a liquid cooling unit in another exemplary embodiment of the present application, such as Figure 1-Figure 4 As shown, the liquid cooling unit 1 includes a cabinet 11, a liquid cooling machine body 12 and a windshield assembly 13. The cabinet 11 encloses a storage space 18, and the liquid cooling machine body 12 and the windshield assembly 13 are assembled in the storage space 18. The windshield assembly 13 cooperates with the inner walls of the liquid cooling machine body 12 and the cabinet 11 respectively to separate the storage space 18 into a first space 181 and a second space 182. The liquid cooling machine body 12 includes an air inlet 111 located in the first space 181 and an air outlet 112 located in the second space 182. The cabinet 11 is provided with an air inlet structure 121 and an air outlet structure 122. The air inlet 111 is arranged in alignment with the air inlet structure 121, and the air outlet 112 is arranged in alignment with the air outlet structure 122.

[0033] Since the windshield assembly 13 of the liquid cooling unit 1 cooperates with the liquid cooling machine body 12 and the inner wall of the cabinet 11 to divide the accommodating space 18 into a first space 181 and a second space 182, the air inlet 111 of the liquid cooling machine body 12 is located in the first space 181, and the air outlet 112 is located in the second space 182, so that the air flowing out of the air outlet 112 is directly discharged through the air outlet structure 122 of the cabinet 11, thereby avoiding the air flowing out of the air outlet 112 from flowing back to the air inlet 111 and affecting the heat dissipation performance of the liquid cooling unit 1.

[0034] In an embodiment of the present application, the structure of the wind shield assembly 13 is associated with the matching relationship between the liquid cooling machine body 12 and the cabinet 11. When the liquid cooling machine body 12 is located at different positions in the cabinet 11, the structure of the wind shield assembly 13 can change accordingly to separate the accommodating space 18 into a first space 181 and a second space 182.

[0035] When the top wall and the two side walls of the liquid cooling machine body 12 between the air inlet 111 and the air outlet 112 are tightly fitted with the inner wall of the cabinet 11, a wind shield can be set only for the gap between the bottom of the liquid cooling machine body 12 and the bottom inner wall of the cabinet 11.

[0036] In some embodiments, the liquid cooling unit 1 further includes a unit tray 113 assembled at the bottom of the cabinet 11, and the liquid cooling machine body 12 is assembled on the unit tray 113. The windshield assembly 13 includes a first baffle 131 assembled at one end of the unit tray 113 close to the air outlet structure 122, and the first baffle 131 includes a first portion 1311 abutting against a side wall of the cabinet 11 provided with the air outlet structure 122. The liquid cooling unit 1 can be placed on the unit tray 113 and pushed into the cabinet 11 by sliding relative to the unit tray 113. A first baffle 131 is provided at one end of the unit tray 113 close to the air outlet structure 122, the first baffle 131 is connected to the unit tray 113, and a first portion 1311 of the first baffle 131 abuts against a side wall of the cabinet 11 on which the air outlet structure 122 is provided, so that the first baffle 131, the unit tray 113, and the side wall of the cabinet 11 on which the air outlet structure 122 is provided form a structure that blocks the air flowing out of the air outlet 112 from flowing back from the gap between the bottom of the liquid cooling machine body 12 and the bottom inner wall of the cabinet 11.

[0037] Among them, a first buffer component 14 can be provided between the first baffle plate 131 and the side wall of the cabinet 11 on which the air outlet structure 122 is provided. The first buffer component 14 can avoid friction and collision between the first baffle plate 131 and the cabinet 11, and can also use the elastic performance of the first buffer component 14 to compensate for the assembly gap between the liquid cooling unit 1, the unit tray 113 and the first baffle plate 131 and the cabinet 11.

[0038] In some embodiments, the liquid cooling unit 1 may further include a mounting foot 114, the mounting foot 114 being assembled on a side of the unit tray 113 facing away from the liquid cooling unit body 12, the first baffle 131 including a second portion 1312 assembled between the mounting foot 114 and the unit tray 113, and a second buffer 15 being provided between the second portion 1312 and the unit tray 113. The second portion 1312 of the baffle is used to achieve fixation between the mounting foot 114, the unit tray 113 and the first baffle 131, and also avoids interference with the structure and function of the first portion 1311. The second buffer 15 can avoid friction and collision between the first baffle 131 and the mounting foot 114 and the unit tray 113, and can also use the elastic performance of the second buffer 15 to compensate for the assembly gap between the liquid cooling unit 1, the unit tray 113, the mounting foot 114 and the first baffle 131 and the cabinet 11.

[0039] The second part 1312 can be bent relative to the first part 1311, so as to facilitate the abutment between the first part 1311 and the side wall of the cabinet 11 provided with the air outlet structure 122 and the assembly of the second part 1312 between the mounting foot 114 and the unit tray 113. For example, the first part 1311 can be arranged vertically, and the second part 1312 can be arranged horizontally.

[0040] When the bottom wall and the two side walls of the liquid cooling machine body 12 between the air inlet 111 and the air outlet 112 are tightly fitted with the inner wall of the cabinet 11, a wind shield can be set only for the gap between the top of the liquid cooling machine body 12 and the top inner wall of the cabinet 11.

[0041] In some embodiments, the wind shield assembly 13 includes a second baffle 132, and the second baffle 132 includes a third part 1321, a fourth part 1322, and a fifth part 1323 connecting the third part 1321 and the fourth part 1322. The third part 1321 is assembled on the top inner wall of the cabinet 11, and the fourth part 1322 is abutted against one end of the top surface of the liquid cooling machine body 12 close to the air outlet structure 122 to block the gap between the top of the liquid cooling machine body 12 and the top inner wall of the cabinet 11, and provide a limiting effect for the liquid cooling machine body 12 in the height direction of the liquid cooling unit 1. Among them, the third part 1321 can be set horizontally to facilitate assembly with the top inner wall of the cabinet 11 and improve the blocking effect. The fourth part 1322 can be set horizontally to facilitate abutment with the top surface of the liquid cooling machine body 12 and improve the blocking effect. The fifth part 1323 can be set vertically to connect the third part 1321 and the fourth part 1322.

[0042] Among them, a third buffer 16 is provided between the fourth portion 1322 and the top surface of the liquid cooling machine body 12. The third buffer 16 can avoid friction and collision between the second baffle 132 and the inner wall of the cabinet 11 and the liquid cooling machine body 12, and can also use the elastic performance of the third buffer 16 to compensate for the assembly gap between the liquid cooling unit 1 and the cabinet 11.

[0043] When the top wall and bottom wall of the liquid cooling machine body 12 between the air inlet 111 and the air outlet 112 are tightly fitted with the inner wall of the cabinet 11, a wind shield can be set only for the gap between the side of the liquid cooling machine body 12 and the side wall of the cabinet 11.

[0044] In some embodiments, the wind shield assembly 13 includes a third baffle 133, and the third baffle 133 includes a sixth part 1331 and a seventh part 1332. The sixth part 1331 is assembled on at least one side inner wall between the top and the bottom of the cabinet 11, and the seventh part 1332 is in contact with the end surface of the liquid cooling machine body 12 close to the air outlet structure 122, so as to limit the liquid cooling machine body 12 in the pushing direction of the liquid cooling machine body 12, and the contact between the seventh part 1332 and the end surface of the liquid cooling machine body 12 can also form a blocking effect to prevent the air from flowing back through the air outlet 112. When there is a gap between one side of the liquid cooling machine body 12 and the side wall of the cabinet 11, a third baffle 133 can be set on the side where the gap is formed, and when there is a gap between both sides of the liquid cooling machine body 12 and the side wall of the cabinet 11, third baffles 133 can be set on the sides where the gap is formed.

[0045] Among them, a fourth buffer 17 may be provided between the seventh portion 1332 and the end surface of the liquid cooling machine body 12. The fourth buffer 17 can prevent the paint film from falling off due to friction and collision between the third baffle 133 and the liquid cooling machine body 12 during the pushing process, and can also use the elastic performance of the fourth buffer 17 to compensate for the assembly gap between the liquid cooling unit 1 and the cabinet 11.

[0046] In addition, the second baffle 132 may further include a first extension portion 1324 bent relative to the fourth portion 1322, and the seventh portion 1332 may include a second extension portion 1333 protruding from the top of the liquid cooling machine body 12, and the first extension portion 1324 abuts against the second extension portion 1333 to form a stable installation effect. The fourth buffer 17 may extend between the first extension portion 1324 and the second extension portion 1333 to avoid friction and collision therebetween, and the elastic performance of the fourth buffer 17 may also be used to compensate for the assembly gap between the second baffle 132 and the third baffle 133.

[0047] It should be noted that the material of the first buffer component 14 , the second buffer component 15 , the third buffer component 16 and the fourth buffer component 17 may be foam, and the foam may be fixed to the components on both sides by bonding.

[0048] In some embodiments, when the liquid cooling machine body 12 is located in the middle of the accommodating space 18, and there are gaps between the top wall, the bottom wall, and the side wall of the liquid cooling machine body 12 located between the air inlet 111 and the air outlet 112 and the inner wall of the cabinet 11, a windshield assembly 13 is provided for the gap surrounding the liquid cooling machine body 12. For example, the windshield assembly 13 includes the above-mentioned first baffle 131, the second baffle 132, and a pair of third baffles 133. The arrangement scheme of the first baffle 131, the second baffle 132, and the third baffle 133 can refer to the above-mentioned embodiment, and will not be repeated here.

[0049] It should be noted that the above-mentioned first baffle 131, second baffle 132 and third baffle 133 can cooperate with one end of the liquid cooling machine body 12 close to the air outlet structure 122, and can also cooperate with any position of the top wall, bottom wall or side wall of the liquid cooling machine body 12 between the air inlet 111 and the air outlet 112 to form a partition of the accommodating space 18, and the present application does not limit this.

[0050] In some embodiments, the cabinet 11 includes a main structure 115 and a back plate structure 116, the back plate structure 116 is assembled to the main structure 115 to enclose the accommodation space 18, the side walls of the main structure 115 and the back plate structure 116 opposite to each other are provided with an air inlet structure 121, and the back plate structure 116 is provided with an air outlet structure 122. The main structure 115 and the back plate structure 116 are assembled to form the cabinet 11 as a whole, providing installation space for the liquid cooling machine body 12 and the windshield assembly 13, thereby improving the assembly convenience of the liquid cooling unit 1.

[0051] The present application further provides a liquid-cooled energy storage device 2, such as Figure 5 As shown, the liquid-cooled energy storage device 2 includes the above-mentioned liquid cooling unit 1.

[0052] Since the windshield assembly 13 of the liquid cooling unit 1 cooperates with the liquid cooling machine body 12 and the inner wall of the cabinet 11 to divide the accommodating space 18 into a first space 181 and a second space 182, the air inlet 111 of the liquid cooling machine body 12 is located in the first space 181, and the air outlet 112 is located in the second space 182, so that the air flowing out of the air outlet 112 is directly discharged through the air outlet structure 122 of the cabinet 11, thereby avoiding the air flowing out of the air outlet 112 from flowing back to the air inlet 111 and affecting the heat dissipation performance of the liquid cooling unit 1.
