[0071] The core of the present application is to provide an energy storage box body to solve the problems of high cost of liquid cooling pipe and large space occupation in the energy storage box body.

[0072] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the 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 the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0073] In order to meet the thermal management requirements of energy storage units (such as battery units) in an energy storage box (such as an energy storage container), an energy storage support frame and a liquid cooling device are usually arranged in the energy storage box, the liquid cooling device comprising a liquid cooling plate and a liquid cooling circulation flow channel, wherein the liquid cooling plate is arranged on the energy storage support frame, the energy storage unit is carried on the liquid cooling plate, the energy storage support frame is used to support the liquid cooling plate and the energy storage unit carried on the liquid cooling plate, the liquid cooling plate is in communication with the liquid cooling circulation flow channel, the liquid cooling circulation flow channel can on the one hand deliver cooling liquid to the liquid cooling plate, and on the other hand receive the cooling liquid flowing out of the liquid cooling plate after heat exchange, so that the liquid cooling plate can cyclically cool the energy storage unit. However, since a plurality of rows and columns of energy storage units are usually arranged on the energy storage support frame, a plurality of rows and columns of liquid cooling plates are also arranged on the energy storage support frame, one column of liquid cooling plates can be regarded as one liquid cooling plate group, and the liquid cooling circulation flow channel needs to be in communication with the plurality of rows and columns of liquid cooling plates, which makes the liquid cooling circulation flow channel need to be arranged with a large number of liquid cooling branch pipes, resulting in that the overall arrangement of the liquid cooling circulation flow channel is relatively complex and the length of the required liquid cooling pipeline is relatively long, causing the cost of the liquid cooling pipeline to be relatively high and the occupied space in the energy storage box to be relatively large.

[0074] Based on this, the embodiments of the present application provide an energy storage box, referring to Figures 1-5 Combining Figure 11 , the energy storage box specifically comprises a liquid cooling device 1 and an energy storage support frame 2, wherein the liquid cooling device 1 comprises at least two columns of liquid cooling plate groups 10 arranged in rows along a first direction (the first direction is specifically the length direction of the energy storage support frame 2) and a liquid cooling circulation flow channel 11 in circulation communication with the liquid cooling plate groups 10, each column of liquid cooling plate groups 10 specifically at least one liquid cooling plate, that is, each column of liquid cooling plate groups 10 can have one liquid cooling plate, or can have a plurality of liquid cooling plates arranged in columns, the liquid cooling circulation flow channel 11 can on the one hand deliver cooling liquid to the liquid cooling plate, and on the other hand receive the cooling liquid flowing out of the liquid cooling plate after heat exchange, so that the liquid cooling plate can cyclically heat-exchange the energy storage unit, specifically, the liquid cooling plate can refrigerate or heat the energy storage unit according to requirements, the liquid cooling circulation flow channel 11 comprises a liquid cooling main path 111, which is mainly used to cyclically supply cooling liquid to each column of liquid cooling plate groups 10; the energy storage support frame 2 comprises a first support frame 21 arranged between adjacent two columns of liquid cooling plate groups 10, referring to Figure 4 , the first support frame 21 is internally provided with a first flow channel 211 and a second flow channel 212 both in communication with the liquid cooling main path 111, the first flow channel 211 is in communication with one column of liquid cooling plate groups 10 of the adjacent two columns of liquid cooling plate groups 10, that is, the first flow channel 211 is in communication with each liquid cooling plate of the column of liquid cooling plate groups 10, and the second flow channel 212 is in communication with another column of liquid cooling plate groups 10 of the adjacent two columns of liquid cooling plate groups 10, that is, the second flow channel 212 is in communication with each liquid cooling plate of the column of liquid cooling plate groups 10.

[0075] It should be noted that the specific structure of the first flow channel 211 and the second flow channel 212 arranged in the first support frame 21 can be that the corresponding flow channel structure is formed inside the first support frame 21, or that corresponding pipelines capable of forming the first flow channel 211 and the second flow channel 212 are arranged in the first support frame 21. In actual application, the configuration can be selected according to actual needs, and no more specific limitation is made here. In addition, the arrangement of the first flow channel 211 and the second flow channel 212 in the first support frame 21 can be that the first flow channel 211 and the second flow channel 212 are arranged on the same vertically arranged support beam of the first support frame 21, or that the first flow channel 211 and the second flow channel 212 are arranged on two different vertically arranged support beams of the first support frame 21, as long as the arrangement requirement can be met. The drawings provided in the present application show that the first flow channel 211 and the second flow channel 212 are arranged on the same vertically arranged support beam of the first support frame 21. Figure 1 -Appendix Figure 12 The first flow channel 211 and the second flow channel 212 are arranged on the same vertically arranged support beam of the first support frame 21.

[0076] In actual application, the energy storage box body is arranged with the first flow channel 211 and the second flow channel 212 which are both communicated with the liquid cooling main line 111 in the first support frame 21, and the first flow channel 211 is communicated with one of the two adjacent rows of liquid cooling plate groups 10, and the second flow channel 212 is communicated with the other of the two adjacent rows of liquid cooling plate groups 10, that is, most of the liquid cooling pipelines between the liquid cooling main line 111 and the liquid cooling plate group 10 are integrated in the first support frame 21. The first support frame 21 not only plays a supporting role of a conventional support frame, but also can act as part of the liquid cooling pipeline, thereby greatly reducing the arrangement and connection work of the liquid cooling pipeline between the liquid cooling main line 111 and the liquid cooling plate group 10, reducing the risk of cooling liquid leakage in the system, and enhancing the stability of the whole liquid cooling system. At the same time, the overall arrangement of the liquid cooling pipeline is simplified, which helps to reduce the cost of the liquid cooling pipeline, and in addition, the liquid cooling pipeline also reduces the occupied space in the energy storage box body, so that the internal design of the whole energy storage box is more regular and beautiful, and the space utilization rate of the energy storage box body is increased.

[0077] In some specific embodiments, referring to Figures 1-5The liquid cooling main path 111 can specifically include a liquid supply main path 111a and a liquid return main path 111b. The liquid supply main path 111a is mainly used to deliver the cooling liquid output by the liquid cooling unit to each liquid cooling plate group 10, and the liquid return main path 111b is mainly used to deliver the cooling liquid flowing out of each liquid cooling plate group 10 to the liquid cooling unit. The first flow channel 211 in the first support frame 21 can be connected to the liquid supply main path 111a, and the second flow channel 212 in the first support frame 21 can be connected to the liquid return main path 111b. At this time, the first flow channel 211 is used to deliver the cooling liquid of the liquid supply main path 111a to the liquid cooling plate group 10 connected thereto, and the second flow channel 212 is used to return the cooling liquid flowing back from the liquid cooling plate group 10 connected thereto to the liquid return main path 111b. Here, the connection mode of a row of liquid cooling plate groups 10 between two adjacent first support frames 21 is taken as an example for description. Each liquid cooling plate of the row of liquid cooling plate groups 10 is in communication with the liquid supply main path 111a through the first flow channel 211 of one of the first support frames 21, and is in communication with the liquid return main path 111b through the second flow channel 212 of the other first support frame 21, so as to realize the circulation of the liquid inflow and return of the liquid cooling plate group 10. By designing in this structure, a certain heat exchange effect can be generated between the first flow channel 211 as the cooling liquid supply and the second flow channel 212 as the cooling liquid return, so that the return cooling liquid of the liquid cooling unit completes a heat exchange in advance, which helps to improve the refrigeration / heating efficiency of the liquid cooling unit.

[0078] Of course, it can be understood that the first flow channel 211 and the second flow channel 212 in the first support frame 21 can also be connected to the liquid supply main path 111a. At this time, the first flow channel 211 and the second flow channel 212 are respectively used to supply cooling liquid to the liquid cooling plate group 10 connected thereto. At this time, the return of the liquid cooling plate group 10 is not specifically limited, and the liquid cooling pipe can be connected to the liquid return main path 111b, or a corresponding return flow channel can be designed in the support frame on the other side of the liquid cooling plate group 10, and the return flow channel is connected to the liquid return main path 111b. The first flow channel 211 and the second flow channel 212 in the first support frame 21 can also be connected to the liquid return main path 111b. At this time, the first flow channel 211 and the second flow channel 212 are respectively used to receive the cooling liquid flowing back from the liquid cooling plate group 10 connected thereto. At this time, the supply of the liquid cooling plate group 10 is not specifically limited, and the liquid cooling pipe can be connected to the liquid supply main path 111a, or a corresponding supply flow channel can be designed in the support frame on the other side of the liquid cooling plate group 10, and the supply flow channel is connected to the liquid supply main path 111a. In actual application, the arrangement can be made according to actual needs, and no more specific limitation is made here.

[0079] It is worth mentioning that when the first flow channel 211 and the second flow channel 212 within the first support frame 21 are connected to the same main path (supply main path 111a or return main path 111b), the corresponding first flow channel 211 and second flow channel 212 can be constructed as the same common flow channel, through which coolant is simultaneously supplied to or returned to the liquid-cooled plate assemblies 10 on both sides of the first support frame 21. For example, the common flow channel in one of two adjacent first support frames 21 is connected to the supply main path 111a to supply coolant to the corresponding liquid-cooled plate assembly 10, while the common flow channel in the other is connected to the return main path 111b to return the coolant of the corresponding liquid-cooled plate assembly 10 to the return main path 111b. The advantage of this structural design is that the supply branch connected to the main supply line 111a and the return branch connected to the main return line 111b are separated from each other, so there is no heat exchange and the supply temperature of the coolant in the supply branch can be guaranteed as much as possible.

[0080] In other specific implementations, the aforementioned main supply line 111a and main return line 111b can be designed on the same side of the upper and lower sides of the energy storage support frame 2, or they can be set on different sides of the upper and lower sides of the energy storage support frame 2. The main supply line 111a and main return line 111b can both be set on the upper side of the energy storage support frame 2; for example, refer to Figure 1 As shown, both the main supply line 111a and the main return line 111b are located on the lower side of the energy storage support frame 2; for example, referring to... Figure 3 As shown, one of the main supply line 111a and the main return line 111b is located on the upper side of the energy storage support frame 2, and the other is located on the lower side of the energy storage support frame 2. Figure 3 Only the configuration shown is a case where the main supply line 111a is located on the lower side of the energy storage support frame 2, and the main return line 111b is located on the upper side of the energy storage support frame 2. This structural design allows the coolant to be supplied and flow away from bottom to top, better ensuring that each liquid cooling plate has sufficient coolant. Since the other configuration is structurally similar, no corresponding diagram is provided, but this does not affect the understanding of the technical solution by those skilled in the art.

[0081] In some other specific implementation schemes, refer to Figure 10 As shown, the energy storage box has internal support beams 31 and internal support vertical beams 32, which together form the internal frame of the energy storage box. The energy storage support frame 2 is installed within the internal frame. (Refer to...) Figure 5 and Figure 8As shown, at least part of the liquid supply main path 111a can be configured as a flow channel structure arranged in the in-tank support cross beam 31; at least part of the liquid return main path 111b can be configured as a flow channel structure arranged in the in-tank support cross beam 31; or at least part of the liquid supply main path 111a can be configured as a flow channel structure arranged in the in-tank support cross beam 31, and at least part of the liquid return main path 111b can be configured as a flow channel structure arranged in the in-tank support cross beam 31. For example, referring to Figure 5 As shown, at least part of the liquid supply main path 111a is configured as a flow channel structure arranged in the in-tank support cross beam 31 at the bottom side of the energy storage tank body, and at least part of the liquid return main path 111b is configured as a flow channel structure arranged in the in-tank support cross beam 31 at the top side of the energy storage tank body. By designing in the above-mentioned structure, the pipe arrangement and connection structure are further reduced, which is more helpful for reducing the cost of the liquid cooling pipe and reducing the occupied space of the liquid cooling pipe in the energy storage tank body.

[0082] In some specific embodiments, referring to Figure 1 , Figure 3 and Figure 5 As shown, the energy storage support frame 2 can further include a second support frame 22 arranged at the two end positions in the first direction, and the second support frame 22 is provided with a third flow channel in communication with the liquid cooling main path 111, and the third flow channel is in communication with the liquid cooling plate group 10 at the corresponding end side. In this way, the liquid inlet flow channel and the liquid return flow channel of the liquid cooling plate group 10 at the two end sides in the first direction can be designed in the first support frame 21 and the second support frame 22 at the two sides of the liquid cooling plate group 10, respectively, so as to reduce the arrangement and connection of the liquid cooling pipe as much as possible.

[0083] In further embodiments, referring to Figure 10 As shown, the energy storage tank body has an in-tank support cross beam 31 and an in-tank support vertical beam 32, and the in-tank support cross beam 31 and the in-tank support vertical beam 32 form an internal tank frame of the energy storage tank body, and the energy storage support frame 2 is arranged in the internal tank frame. At least part of the support beam of the second support frame 22 is configured as the in-tank support vertical beam 32. By designing in this structure, the in-tank support vertical beam 32 is reused, which can not only be used to form the internal support frame of the energy storage tank body, but also can be part of the energy storage support frame 2, and can also serve as the internal flow channel structure of the second support frame 22, which is helpful for simplifying the number of internal support beams of the energy storage tank body.

[0084] In some specific embodiments, referring to 8, Figure 9 In combination with Figure 11 and Figure 12As shown, the liquid cooling plate group 10 can specifically include a first working plate group 101 and a second working plate group 102 distributed in an up-down direction along the height direction of the energy storage support frame 2. Specifically, the liquid cooling plate group 10 has a plurality of liquid cooling plates arranged in a column, wherein the first working plate group 101 has a plurality of liquid cooling plates, which can also be one or more, and the second working plate group 102 has a plurality of liquid cooling plates, which can also be one or more; the liquid cooling main line 111 includes a first liquid cooling main line 1111 and a second liquid cooling main line 1112 respectively arranged on the upper and lower sides of the energy storage support frame 2; the first flow channel 211 includes a first upper section flow channel 2111 and a first lower section flow channel 2112 distributed in an up-down direction along the height direction of the energy storage support frame 2 and separated from each other, and the second flow channel 212 includes a second upper section flow channel 2121 and a second lower section flow channel 2122 distributed in an up-down direction along the height direction of the energy storage support frame 2 and separated from each other; the first upper section flow channel 2111 and the second upper section flow channel 2121 are both in communication with the first liquid cooling main line 1111, which can specifically include a liquid supply main line 111a and a liquid return main line 111b, the first upper section flow channel 2111 is in communication with one of the first working plate groups 101 in the adjacent two columns of the first working plate groups 101, and the second upper section flow channel 2121 is in communication with another of the first working plate groups 101 in the adjacent two columns of the first working plate groups 101; the first lower section flow channel 2112 and the second lower section flow channel 2122 are both in communication with the second liquid cooling main line 1112, the first lower section flow channel 2112 is in communication with one of the second working plate groups 102 in the adjacent two columns of the second working plate groups 102, and the second lower section flow channel 2122 is in communication with another of the second working plate groups 102 in the adjacent two columns of the second working plate groups 102. Such design makes the first working plate group 101 and the second working plate group 102 supply cooling liquid, i.e., the liquid cooling plates in the energy storage cabinet form two layers of upper and lower layers to supply cooling liquid, which is beneficial to evenly distribute the liquid flow rate of the liquid cooling plates at the top and the bottom of the energy storage cabinet.

[0085] In some specific embodiments, with reference to Figures 1-4 As shown, the first support frame 21 is provided with a first main line interface 213 and a second main line interface 214, the first flow channel 211 is in communication with the liquid cooling main line 111 through the first main line interface 213 cooperating with the first main line connecting pipe 112, and the second flow channel 212 is in communication with the liquid cooling main line 111 through the second main line interface 214 cooperating with the second main line connecting pipe 113. By designing the first main line interface 213 and the second main line interface 214, the first flow channel 211 and the second flow channel 212 are more convenient to connect to the liquid cooling main line 111, and the required liquid cooling pipeline is shorter, which helps to save costs. Of course, the first flow channel 211 and the second flow channel 212 can also be directly designed to be connected to the corresponding liquid cooling main line 111.

[0086] In some other specific embodiments, the first support frame 21 may be provided with a first cold plate interface 215 and a second cold plate interface 216. The number of the first cold plate interfaces 215 and the second cold plate interfaces 216 corresponds to the number of liquid cooling plates in the liquid cooling plate assembly 10. The first flow channel 211 is connected to the corresponding liquid cooling plate in the liquid cooling plate assembly 10 through the first cold plate interface 215, and the second flow channel 212 is connected to the corresponding liquid cooling plate in the liquid cooling plate assembly 10 through the second cold plate interface 216. It is understood that the first cold plate interface 215 and the second cold plate interface 216 can be a single interface connected to the liquid cooling plate with a short connecting pipe, or both the first cold plate interface 215 and the second cold plate interface 216 can have a connecting pipe with an interface matching the liquid cooling plate. By designing the above structural form, the connection between each liquid cooling plate in the liquid cooling plate assembly 10 and the first flow channel 211 and the second flow channel 212 becomes more convenient.

[0087] In some specific implementation plans, refer to Figure 6 and Figure 7 As shown, where Figure 6 In the given example, the first flow channel 211 supplies liquid, the second flow channel 212 returns liquid, and the first flow channel 211 is the lower end liquid inlet, that is, the first main channel interface 213 is arranged near the lower end of the first flow channel 211, and the second flow channel 212 is the upper end liquid outlet, that is, the second main channel interface 214 is arranged near the upper end of the second flow channel. Figure 7In the given example, the first flow channel 211 supplies liquid, the second flow channel 212 returns liquid, and the first flow channel 211 is an upper end liquid inlet, that is, the first main channel interface 213 is arranged close to the upper end of the first flow channel 211, and the second flow channel 212 is a lower end liquid outlet, that is, the second main channel interface 214 is arranged close to the lower end of the second flow channel. Specifically, when the first flow channel 211 is in communication with the liquid supply main channel 111a, the first flow channel 211 can be configured in a structure with gradually increasing cross-sectional area along the direction of the flow of the cooling liquid therein, so as to avoid the situation that the flow of the first cold plate interface 215 close to the first main channel interface 213 is large, and the flow of the first cold plate interface 215 far from the first main channel interface 213 is small; similarly, when the second flow channel 212 is in communication with the liquid return main channel 111b, the second flow channel 212 can be configured in a structure with gradually decreasing cross-sectional area along the direction of the flow of the cooling liquid therein, so as to avoid the situation that the flow of the second cold plate interface 216 close to the second main channel interface 214 is large, and the flow of the second cold plate interface 216 far from the second main channel interface 214 is small. The first flow channel 211 configured in a structure with gradually increasing cross-sectional area along the direction of the flow of the cooling liquid therein and the second flow channel 212 configured in a structure with gradually decreasing cross-sectional area along the direction of the flow of the cooling liquid therein can be selected alternatively, or arranged simultaneously. By being designed in such a structure, the flow of the liquid cooling plate connected to the liquid supply branch and the liquid return branch can be effectively balanced, so that the refrigeration / heating effect of the energy storage unit carried on the liquid cooling plate is more balanced.
