DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0043] In the description of the present application, it should be understood that the terms "height", "thickness", "up", "down", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In the description of the present application, "multiple" means two or more, and at least one means one, two or more, unless otherwise clearly and specifically defined. In the description of the present application, "vertical" means completely vertical at 90° or almost completely vertical, for example, an angle in the range of 80° to 100° is considered vertical.

[0044] It should also be noted that in the drawings of the embodiments of the present application, the arrow marked with X represents the height direction X of the energy storage cabinet. The height direction X is introduced to more clearly describe the structure and relative position relationship of the components in the energy storage cabinet. In actual applications, the height direction X may change according to different placement methods of the energy storage cabinet.

[0045] As a preface to the embodiments of the present application, in a conventional energy storage cabinet, the liquid cooling unit is arranged on the cabinet door. When the cabinet door is closed, the liquid cooling unit protrudes from the surface of the cabinet door, and will occupy the lateral space inside the energy storage cabinet, that is, the space inside the energy storage cabinet in the direction of the protrusion of the liquid cooling unit, so that the components distributed relative to the liquid cooling unit are easily restricted by size and cannot be reasonably arranged, thereby reducing the space utilization rate of the energy storage cabinet; in addition, the liquid cooling unit is arranged on the cabinet door, which will increase the load-bearing capacity of the cabinet door, and may cause the cabinet door and the cabinet body to deform and deform, thereby causing the cabinet door to bend, deform or sag. These deformations and deformations may cause the sealing surface between the cabinet door and the cabinet body to no longer fit completely, forming a gap or uneven contact, thereby affecting the sealing performance. In addition, the liquid cooling unit is arranged on the cabinet door, and the pipeline needs to pass from the cabinet door into the battery compartment and the electrical compartment. When the cabinet door is opened and closed, it is bound to cause disturbances to the joints of the pipeline, thereby causing the joints to wear and affect their sealing.

[0046] Please combine Figure 1 and Figure 2The energy storage cabinet of the embodiment of the present application includes a cabinet body 1, a battery module 2, a power module 3, a switch box 4 and a liquid cooling unit 5. The cabinet body 1 is provided with a battery compartment 11 and an electrical compartment 12 spaced apart from each other. The battery compartment 11 and the electrical compartment 12 are independent of each other, that is, the battery compartment 11 and the electrical compartment 12 are not connected on the side close to each other. The battery module 2 is arranged in the battery compartment 11. The number of battery modules 2 can be single or multiple. The specific number is determined according to the application scenario of the energy storage cabinet and is not limited here. The power module 3 is arranged in the electrical compartment 12. The power module 3 is a PCS (power conversion system) for storing and releasing electric energy. The switch box 4 is used to connect the power module 3 and the battery module 2. The liquid cooling unit 5 includes a liquid cooling host 51 and an air cooling module 52. The liquid cooling host 51 and the switch box 4 are both arranged in the battery compartment 11 or in the electrical compartment 12. The liquid cooling host 51 is used to cool the battery module 2 and the power module 3 so that the battery module 2 and the power module 3 are within a safe ambient temperature range to reduce the possibility of thermal runaway. The battery module 2, the power module 3 and the switch box 4 are arranged in multiple layers in the height direction X of the cabinet 1, and the liquid-cooled host 51 and the switch box 4 are located on the same layer, that is, the liquid-cooled host 51 and the switch box 4 are arranged on the left and right of the layer. The left-right arrangement can be understood as the cabinet opening of the cabinet 1 facing the user, and the liquid-cooled host 51 and the switch box 4 are arranged on the left and right facing the user.

[0047] The air cooling module 52 is arranged on the top side of the cabinet 1 and is connected to the liquid cooling host 51 through a pipe. The liquid cooling host 51 transports the cooling medium to the battery module 2 and the power module 3 through a pipe for heat exchange. The cooling medium after the heat exchange flows through the air cooling module 52 through the pipe. The air cooling module 52 cools the cooling medium in the pipe by heat exchange with the air. The air cooling module 52 is located at the top of the cabinet 1, which frees up the space around the cabinet 1, providing a basis for combining multiple energy storage cabinets, and can reduce mutual interference between energy storage cabinets after combining, thereby improving the energy density of the energy storage system. Exemplarily, energy storage cabinets can be arranged on the left, right and rear sides of a single energy storage cabinet to achieve a combination of three-sided cabinets.

[0048] The liquid-cooled host 51 is arranged in the battery compartment 11 or the electrical compartment 12, and the air-cooling module 52 is arranged separately from the liquid-cooled host 51, and both are installed in the cabinet 1, so that the cabinet door 8 of the energy storage cabinet can maintain its original deadweight, and avoid deformation of the connection structure between the cabinet door 8 and the cabinet 1 or a large gap due to excessive load, so that the cabinet door 8 can maintain a close fit with the cabinet 1 to achieve a stable seal between them. Since the liquid-cooled host 51 is arranged in the energy storage cabinet, the pipeline of the liquid-cooled host 51 can be arranged in the cabinet 1, directly connected to the battery module 2 and the power module 3, and the pipeline and the cabinet door 8 are independent of each other, which plays a protective role for the pipeline.

[0049] The switch box 4 and the liquid-cooled host 51 are arranged on the same layer and arranged left and right, making full use of the side space of the switch box 4. Compared with the arrangement of the switch box 4 and the liquid-cooled host 51 along the height direction X, there is no need to expand the space of the electrical compartment 12 in the height direction X, and the lateral space of the energy storage cabinet is released, so that each component can be reasonably arranged, thereby improving the space resource utilization rate of the energy storage cabinet.

[0050] Please refer to Fig.13 In this embodiment, the air cooling module 52 includes a shell 521 and a fan 522. The shell 521 is provided with a front air outlet 523, a rear air outlet 524 and a top air outlet 525. When working, the fan 522 introduces air flow from the front air outlet 523 and the rear air outlet 524, so that the air flow exchanges heat with the cooling medium in the pipeline, and then is discharged from the top air outlet 525.

[0051] Please combine Figure 2 , Figure 3 and Figure 4 In some embodiments, the switch box 4 and the liquid cooling host 51 are both disposed in the battery compartment 11 and are located on a side of the battery module 2 close to the power module 3 .

[0052] Alternatively, the switch box 4 and the liquid cooling host 51 are both disposed in the battery compartment 11 and located on a side of the battery module 2 away from the power module 3 .

[0053] When the switch box 4 and the liquid cooling host 51 are located on the side of the battery module 2 close to the power module 3, the switch box 4 and the power module 3 are close to each other, which can reduce the length of the line connecting the switch box 4 and the power module 3 and reduce the loss of current transmission. When the switch box 4 and the liquid cooling host 51 are located on the side of the battery module 2 far from the power module 3, the switch box 4 and the power module 3 are far away from each other, which can reduce the electrical interference of the power module 3 to the switch box 4 on the one hand, and make the liquid cooling host 51 and the air cooling module 52 close to each other, which can shorten the length of the pipeline between the two.

[0054] Please combine Figures 7 to 10 In some embodiments, the liquid cooling host 51 has a dehumidification port 511, which is connected to the battery compartment 11. The liquid cooling host 51 inhales the air in the battery compartment 11 through the dehumidification port 511, and uses the surplus cooling capacity of the liquid cooling host 51 to reduce the internal temperature of the liquid cooling host 51 module, thereby achieving the dehumidification effect, and then sends the dehumidified air into the battery compartment 11 to form a dehumidification cycle to reduce the air humidity in the battery compartment 11, so that the battery module 2 is in a relatively dry environment, thereby reducing the occurrence of short circuits and corrosion in the battery module 2.

[0055] In this embodiment, the dehumidification port 511 includes an air inlet 5111 and an air outlet 5112, which are arranged at intervals and are both connected to the battery compartment 11. When the liquid-cooled host 51 performs a dehumidification operation, the air in the battery compartment 11 is input from the air inlet 5111, and then output from the air outlet 5112 after being dehumidified. In one embodiment, a water receiving tray may be provided below the dehumidification module in the liquid-cooled host 51, and the drain port of the water receiving tray is connected to the outside of the cabinet 1 through a hose. The water receiving tray is used to receive the condensed water generated by the condenser in the dehumidification module, and discharge the condensed water to the outside of the cabinet 1 through the hose, so as to keep the environment of the liquid-cooled host 51 dry.

[0056] Since the liquid-cooled host 51 is disposed in the battery compartment 11, the dehumidification port 511 can be selectively disposed on one of the multiple outer surfaces of the liquid-cooled host 51, and it is only necessary to ensure that the dehumidification port 511 is spaced apart from the surrounding components to prevent the airflow from being blocked. Exemplarily, the dehumidification port 511 can be disposed on a side of the liquid-cooled host 51 away from the cabinet opening of the cabinet 1, and opposite to the cabinet opening of the cabinet 1; or, the dehumidification port 511 can be disposed on a side of the liquid-cooled host 51 opposite to the switch box 4, so that there is a larger gap between the dehumidification port 511 and the inner wall of the cabinet 1 facing it, thereby ensuring smooth airflow.

[0057] Please combine Figure 5 and Figure 6 In some embodiments, the switch box 4 and the liquid cooling host 51 are both arranged in the electrical compartment 12 and are located on the side of the power module 3 away from the battery module 2. Alternatively, the switch box 4 and the liquid cooling host 51 are both arranged in the electrical compartment 12 and are located on the side of the power module 3 close to the battery module 2. The switch box 4 is arranged in the electrical compartment 12. On the one hand, the battery module 2 can be isolated from the switch box 4 and the power module 3, reducing the electrical interference of the switch box 4 and the power module 3 to the battery module 2. On the other hand, the spatial distance between the switch box 4 and the power module 3 is closer, which can simplify the wiring of the switch box 4 and the power module 3.

[0058] Please combine Figure 7 and Figure 8 In some embodiments, the energy storage cabinet further includes a partition 6, which is disposed in the cabinet body 1, and the partition 6 divides the internal space of the cabinet body 1 into a battery compartment 11 and an electrical compartment 12. An opening 61 is provided through the partition 6. The liquid-cooled host 51 has a dehumidification port 511, and the opening 61 is provided corresponding to the dehumidification port 511. Exemplarily, the dehumidification port 511 is provided on the top side of the liquid-cooled host 51 to shorten the distance between the dehumidification port 511 and the opening 61, and the opening 61 is opposite to the dehumidification port 511. The liquid-cooled host 51 inhales the air in the battery compartment 11 through the opening 61 for dehumidification, and then discharges the dehumidified air into the battery compartment 11 through the opening 61.

[0059] Please combine Fig.11 and Fig.12 In some embodiments, the energy storage cabinet further includes a dehumidification duct 7, which is disposed in the electrical compartment 12. The dehumidification duct 7 seals and connects the dehumidification port 511 and the opening 61, and enables the liquid-cooled host 51 to connect to the battery compartment 11 through the opening 61. The dehumidification duct 7 makes up for the distance between the dehumidification port 511 and the opening 61, so that the position of the dehumidification port 511 can be selectively set on different sides of the liquid-cooled host 51, meeting the requirements of different distribution positions of the liquid-cooled host 51 and different lines and pipeline arrangements in the energy storage cabinet. With the liquid-cooled host 51 disposed in the electrical compartment 12, when the cabinet door 8 of the energy storage cabinet is closed, the side of the cabinet door 8 facing the inside of the cabinet body 1 can avoid the structure protruding toward the partition 6, so that the cabinet door 8 can cooperate with the partition 6 to separate the battery compartment 11 and the electrical compartment 12, thereby reducing the environmental interference between them.

[0060] Please combine Fig.11 and Fig.12 In some embodiments, the dehumidification port 511 includes an air inlet 5111 and an air outlet 5112, and the air inlet 5111 and the air outlet 5112 are arranged at intervals and are both connected to the battery compartment 11. Accordingly, in order to match the air inlet 5111 and the air outlet 5112, the dehumidification air duct 7 has at least two channels, and the two channels are not connected to each other, one of the channels is used to communicate with the air inlet 5111, and the other channel is used to communicate with the air outlet 5112, and the two channels are integrated in one dehumidification air duct 7 to improve the integration of the dehumidification air duct 7.

[0061] Please combine Figure 7 and Fig.11 In some embodiments, the cabinet 1 includes a first inner wall 13, and the dehumidification port 511 is arranged toward the first inner wall 13. Since the cabinet 1 has multiple first inner walls 13, the dehumidification port 511 is arranged toward the first inner wall 13, which means that the dehumidification port 511 can be set at different positions of the liquid cooling host 51, such as different outer sides of the liquid cooling host 51.

[0062] The dehumidification air duct 7 includes a first tube body 71 and a second tube body 72. The first tube body 71 is arranged on the liquid cooling host 51 and communicated with the dehumidification port 511. The second tube body 72 is arranged between the first tube body 71 and the partition 6 and communicated with the first tube body 71 and the opening 61. The first tube body 71 and the second tube body 72 connect the dehumidification port 511 with the battery compartment 11. An angle is formed between the first tube body 71 and the second tube body 72, so that the dehumidification air duct 7 is in a bent shape to meet the connection of the relative positions of the dehumidification port 511 and the opening 61 when they are not facing each other. The size of the angle can be determined according to the distance between the dehumidification port 511 and the opening 61 in the horizontal direction. In this embodiment, the angle is 90° to shorten the overall length of the dehumidification air duct 7 as much as possible and reduce the obstruction of the dehumidification air duct 7 to the internal lines and pipelines of the energy storage cabinet.

[0063] Please combine Figure 7 and Fig.11 In some embodiments, the first inner wall 13 extends along the height direction of the cabinet 1, that is, the first inner wall 13 can be the left wall, right wall or rear wall of the cabinet 1, the rear wall is arranged opposite to the cabinet door 8, and the left wall and the right wall are distributed on both sides of the rear wall; correspondingly, the dehumidification port 511 is located on the outer side of the liquid cooling host 51. The first tube body 71 is connected with the dehumidification port 511, the second tube body 72 is perpendicular to the first tube body 71 and upward, and is connected with the opening 61. The dehumidification air duct 7 is arranged between the liquid cooling host 51 and the first inner wall 13, which can reduce the interference with the movement of the liquid cooling host 51 or the power module 3 in and out of the energy storage cabinet, and the possible obstruction after the cabinet door 8 is closed, and ensure the separation requirements of the battery compartment 11 and the electrical compartment 12. During assembly, after the liquid cooling host 51 is pushed into the electrical compartment 12, the dehumidification port 511 just docks with the first tube body 71 and is sealed and connected, which is convenient for installation.

[0064] In some other embodiments, the number of dehumidification ports 511 can be multiple, distributed on different sides of the liquid cooling host 51, and then arranged opposite to at least two of the left wall, the right wall or the rear wall; or, multiple dehumidification ports 511 are arranged on the same outer side of the liquid cooling host 51, and are arranged opposite to any of the left wall, the right wall or the rear wall. The use of multiple dehumidification ports 511 can increase the dehumidification amount of the gas inside the cabinet 1 per unit time on the one hand, and increase the path and direction of air entering and exiting the dehumidification ports 511 on the other hand, thereby improving the uniformity of dehumidification inside the cabinet 1 and reducing the dehumidification dead zone.

[0065] Please combine Figure 5 and Fig.12 In some embodiments, the switch box 4 and the liquid cooling host 51 are both arranged in the electrical compartment 12 and are located on the side of the power module 3 close to the battery module 2. Since the liquid cooling host 51 is located above the power module 3, in order to reduce the interference of the dehumidification duct 7 on the movement of the power module 3, the dehumidification port 511 is arranged toward the partition 6, and the dehumidification duct 7 is arranged between the liquid cooling host 51 and the partition 6. Since the liquid cooling host 51 is located below the partition 6, the minimum distance between the two is the distance between the two opposite surfaces of the liquid cooling host 51 and the partition 6. Therefore, the dehumidification port 511 is arranged toward the partition 6 to reduce the length of the dehumidification duct 7 to meet the limited space requirements in the electrical compartment 12. In order to further facilitate the installation of the dehumidification duct 7, the dehumidification port 511 is arranged on the side of the liquid cooling host 51 close to the cabinet port, so that the dehumidification duct 7 can have enough space facing the outside of the cabinet 1 for personnel to operate during installation.

[0066] Please refer to Figure 7In some embodiments, the energy storage cabinet further includes an explosion venting plate 9, an explosion venting hole 90 is provided on the cabinet body 1, the explosion venting hole 90 is located on the side of the battery compartment 11 away from the electrical compartment 12, the explosion venting hole 90 is communicated with the battery compartment 11, and the explosion venting plate 9 is connected to the cabinet body 1 and covers the explosion venting hole 90. When the battery module 2 has a thermal runaway and causes the gas in the battery compartment 11 to accumulate continuously, the pressure in the battery compartment 11 gradually increases, and the explosion venting plate 9 constitutes a weak area of ​​the cabinet body 1, which will be broken first under the pressure in the battery compartment 11 to achieve the purpose of exhaust and pressure relief, thereby reducing the possibility of explosion of the battery compartment 11.
