Description

Technical Field

[0001] The present application relates to the technical field of temperature-controlled energy storage devices, and in particular to an energy storage device. Background Art

[0002] Battery energy storage devices store and release energy through electrochemical reactions. Energy storage systems generate significant heat during operation. If this heat is not dissipated promptly, the internal temperature of the device will rise, affecting performance and even posing a risk of explosion. Furthermore, operating temperatures that are too low can cause severe battery power loss, improper charging and discharging, and reduced battery life. Temperature-controlled air conditioning can adjust the temperature within industrial and commercial energy storage cabinets, ensuring they operate within the appropriate temperature range.

[0003] Commercial energy storage cabinet air conditioners on the market primarily include air-cooled and liquid-cooled models. Liquid-cooled temperature control systems are currently bulky and heavy, making them difficult to repair, replace, and move. Their large size leads to high costs and significant floor space, which squeezes out space for energy storage batteries. Furthermore, the outlet pipe layout of the valve body connecting the refrigerant pipeline to the refrigeration unit in these air conditioners is not rational, making refrigerant pipeline connection inconvenient.

[0039] See also Figure 1 The present application provides an energy storage device. The energy storage device may be a battery energy storage device. The energy storage device may be an industrial and commercial energy storage cabinet.

[0040] In some embodiments of the present application, the energy storage device includes a cabinet 1. The cabinet 1 has an opening formed on its front side. Batteries can be installed in the cabinet 1 through the opening. The cabinet 1 can be roughly rectangular. It is understood that in other embodiments, the cabinet 1 can also have a hollow structure of other shapes.

[0041] A storage chamber 11 is formed in the cabinet 1. The storage chamber 11 may include a battery compartment for storing the battery 4. The storage chamber 11 may also include a refrigeration module compartment for storing a refrigeration module.

[0042] In some embodiments of the present application, a plurality of relatively arranged shelves may be provided in the battery compartment to form a plurality of shelf spaces, and each shelf space may be used to place a battery 4 separately.

[0043] In other embodiments, the battery compartment can be divided into multiple sub-storage chambers by partitions, and each sub-storage chamber can serve as an independent storage space.

[0044] In some embodiments of the present application, multiple sub-storage chambers can be separated and arranged up and down.

[0045] In some embodiments of the present application, multiple sub-storage chambers can be separated and arranged on the left and right sides.

[0046] In some embodiments of the present application, the energy storage device may include a cabinet door (not shown). The cabinet door is rotatably connected to the front side of the cabinet 1. The cabinet door is configured to seal the cabinet 1 and reduce heat transfer between the interior of the cabinet 1 and the external environment.

[0047] In some embodiments of the present application, the cabinet door may be a rotary door structure, which is rotatably connected to a side of the cabinet body 1 where the opening is provided.

[0048] Specifically, the cabinet door and the cabinet body 1 can be connected by a hinge, so that the cabinet door can rotate around the axis of the hinge to open and close the cabinet door, and then open and close the storage chamber 11.

[0049] Figure 2 This is a schematic diagram of the structure of the connection between the battery and the direct cooling plate assembly provided in this application.

[0050] like Figure 2 As shown, in some embodiments of the present application, the energy storage device may include a direct cooling plate assembly 3. The direct cooling plate assembly 3 is arranged in the storage chamber 11 for heat exchange with the battery 4. The direct cooling plate assembly 3 is arranged at the bottom of the battery 4 and contacts the battery 4 for heat exchange. The direct cooling method has high heat exchange efficiency and can stably maintain the operating temperature of the battery 4 within a normal range. It is understandable that in other embodiments, liquid cooling and other methods can also be used to exchange heat with the battery 4.

[0051] In some embodiments of the present application, in order to improve the sealing performance of the connection between the refrigerant pipeline 25 and the direct cooling plate assembly 3 , the refrigerant pipeline 25 is connected to the direct cooling plate assembly 3 via a secondary sealing pressure plate structure 31 .

[0052] Figure 3 This is a schematic structural diagram of the direct cooling plate assembly provided in this application from the first perspective. Figure 4 This is a schematic structural diagram of the direct cooling plate assembly provided in this application from a second perspective.

[0053] like Figure 3 and Figure 4 As shown, in some embodiments of the present application, the direct cooling plate assembly 3 may include a direct cooling plate 32. The direct cooling plate 32 includes a first sub-direct cooling plate 321 and a second sub-direct cooling plate 322, and the first sub-direct cooling plate 321 and the second sub-direct cooling plate 322 are stacked. The first sub-direct cooling plate 321 is configured as a flat plate, and the battery 4 is arranged on the side of the first sub-direct cooling plate 321 facing away from the second sub-direct cooling plate 322, and a refrigerant flow channel 3221 is formed on the second sub-direct cooling plate 322. The refrigerant flow channel 3221 protrudes toward the first sub-direct cooling plate 321, reducing the distance between the first sub-direct cooling plate 321 and the second sub-direct cooling plate 322, thereby improving the heat exchange efficiency between the first sub-direct cooling plate 321 and the second sub-direct cooling plate 322 to a certain extent.

[0054] In some embodiments of the present application, an insulating thermally conductive adhesive layer (not shown) is provided on the side of the first direct cooling plate 321 facing the battery. The insulating thermally conductive adhesive has good thermal conductivity and heat dissipation properties, which can improve the heat exchange effect between the battery and the first direct cooling plate 321.

[0055] like Figure 1As shown, in some embodiments of the present application, the energy storage device includes a vertical direct cooling air conditioner 2. The vertical direct cooling air conditioner 2 is arranged in the refrigeration module compartment of the cabinet 1. The vertical direct cooling air conditioner 2 extends in the height direction and occupies a small installation area, which is suitable for use in occasions with limited installation area. The vertical direct cooling air conditioner 2 is connected to the direct cooling plate assembly 3 through a refrigerant pipeline 25, so that the refrigerant forms a loop between the direct cooling plate assembly 3 and the vertical direct cooling air conditioner 2, thereby realizing continuous regulation of the operating temperature of the battery 4 by the refrigerant.

[0056] When the vertical direct cooling air conditioner 2 is in cooling mode, the battery 4 is cooled. When the vertical direct cooling air conditioner 2 is in heating mode, the battery 4 is heated.

[0057] Figure 5 This is a schematic diagram of the structure of the vertical direct cooling air conditioner provided in this application from the first perspective; Figure 6 This is a structural diagram of the vertical direct cooling air conditioner provided in this application from a second perspective; Figure 7 This is a structural schematic diagram of the vertical air conditioner provided in this application from a third perspective.

[0058] like Figures 5 to 7 As shown, in some embodiments of the present application, the vertical direct cooling air conditioner 2 includes a housing 21, a refrigeration unit 22 and a refrigerant shut-off valve 23. The refrigeration unit 22 is disposed in the housing 21 and is used to adjust the temperature of the battery 4.

[0059] The refrigeration unit 22 includes a compressor 221, a heat exchanger 222, a regenerator 223, and a cooling fan 224. The compressor 221, heat exchanger 222, regenerator 223, and direct cooling plate 32 are sequentially connected via refrigerant piping 25 to form a refrigerant circulation loop. Throttling devices can be installed at the refrigerant inlet and outlet of the direct cooling plate 32 to adjust the refrigerant flow rate in the direct cooling plate 32, thereby adjusting the heat exchange efficiency between the refrigerant and the battery 4.

[0060] like Figure 6 As shown, the refrigerant piping 25 includes an internal piping 252 and an external piping 251. The internal piping 252 is integrated into the housing 21 and can be installed and removed along with the vertical direct-cooling air conditioner 2. The external piping 251 can include two main lines 2511 and multiple parallel branches 2512 connected between the main lines 2511. The two main lines 2511 and each parallel branch 2512 are connected at both ends via two-way shutoff valves. The parallel branches 2512 are connected to the direct-cooling plate 32 via the pressure plate structure 31.

[0061] Figure 8 This is a structural schematic diagram of the vertical direct cooling air conditioner provided in this application from the fourth perspective.

[0062] like Figure 8As shown, in some embodiments of the present application, the housing 21 includes a panel 211, a top panel 212, a bottom panel 213, a left side panel 214, a right side panel (not shown), and a back panel 216. The panel 211, the top panel 212, the bottom panel 213, the left side panel 214, the right side panel 215, and the back panel 216 together form the housing 21. The housing 21 is made of multiple panels and is easy to disassemble and assemble, and is convenient for cleaning and maintenance.

[0063] The housing 21 is formed with an air outlet 2161. The air outlet 2161 can be located on at least one side of the top or rear portion of the housing 21. Specifically, the air outlet 2161 can be located on the top panel 212 of the housing 21, or on the back panel 216 of the housing 21, or both. This arrangement ensures that the air outlet 2161 has a larger area while minimizing airflow obstruction, ensuring effective airflow.

[0064] like Figure 6 and Figure 7 As shown, the heat dissipation fan 224 is disposed between the heat exchanger 222 and the air outlet 2161 to discharge the heat of the heat exchanger 222 through the air outlet 2161 during cooling.

[0065] The air outlet 2161 is provided with a grille, which can prevent dust and other impurities from entering the interior of the housing 21 and avoid affecting the refrigeration unit 22.

[0066] like Figures 5 to 7 As shown, in some embodiments of the present application, Figure 5 As shown, the housing 21 may be provided with a return air vent 2111. The return air vent 2111 is provided at the front side of the housing 21. The return air vent 2111 extends along the height direction of the housing 21. The panel 214 is located at the front side of the housing 21, and the return air vent 2111 is formed on the panel 214.

[0067] The return air inlet 2111 is provided with a grille to prevent impurities from entering the return air inlet 2111 .

[0068] Figure 9 This is a schematic diagram of the structure of the panel provided in this application from the first perspective.

[0069] In some embodiments of the present application, Figure 9As shown, a guide rail 2112 is provided on the inner side of the panel 214. The guide rail 2112 is provided on at least two opposite outer edges of the return air outlet 2111. The vertical direct cooling air conditioner 2 also includes a filter 217. The filter 217 is mounted on the guide rail 2112 and covers the return air outlet 2111. Installing the filter 217 on the inner side of the return air outlet 2111 can further block dust and other impurities in the air. The filter 217 is installed through the guide rail 2112, which makes it easy to disassemble and assemble the filter 217. It can be removed regularly for cleaning to ensure the return air effect of the return air outlet 2111.

[0070] In some embodiments, such as Figure 9 As shown, guide rails 2112 are arranged around the outer periphery of return air outlet 2111, and filter screen 217 is confined within the space enclosed by guide rails 2112. A locking block is provided on the edge of filter screen 217, and a snap hole is provided on guide rails 2112 to engage with the locking block. Filter screen 217 and guide rails 2112 are fastened together via the locking block and snap hole, preventing filter screen 217 from shifting and causing dust and other impurities to enter the interior of housing 21.

[0071] In other embodiments, the guide rail 2112 can be set above and below the return air outlet 2111, the upper part of the filter 217 is connected to the guide rail 2112 above the return air outlet 2111, and the lower part of the filter 217 is connected to the guide rail 2112 below the return air outlet 2111.

[0072] In other embodiments, the guide rail 2112 can be set above and below the return air outlet 2111, as well as on one of the left and right sides. The filter 217 can slide into the guide rail 2112 from the side of the return air outlet 2111 where the guide rail 2112 is not set. The edges of the filter 217 are respectively connected to the guide rails 2112 in three directions outside the return air outlet 2111, and the guide rail 2112 located on the left or right side of the return air outlet 2111 can also play a certain limiting role on the filter 217, thereby preventing the filter 217 from shifting along the length direction of the return air outlet 2111.

[0073] Figure 10 This is a schematic diagram of the structure of the panel provided in this application from the second viewing angle.

[0074] In some embodiments of the present application, Figure 9 and Figure 10As shown, the housing 21 may be provided with a refrigerant pipeline interface 2113. The refrigerant pipeline interface 2113 is provided on the panel 214. The refrigerant pipeline interface 2113 includes a first interface 21131 and a second interface 21132. The first interface 21131 is provided with a refrigerant outflow pipe, and the second interface 21132 is provided with a refrigerant inflow pipe. The refrigerant inflow pipe referred to here is the refrigerant pipeline 25 for the refrigerant to enter the refrigeration unit 22, and the refrigerant outflow pipe refers to the refrigerant pipeline 25 for the refrigerant to flow out of the refrigeration unit 22. The refrigerant inflow pipe and the refrigerant outflow pipe are two main pipes 2511 in the external pipes 251 of the vertical direct-cooling air conditioner 2.

[0075] In some embodiments, the refrigerant pipe interface 2113 is disposed above the return air port 2111 .

[0076] In other embodiments, the refrigerant pipeline interface 2113 may also be disposed below the return air port 2111 .

[0077] The direct cooling plate 32 and the refrigerant pipeline 25 are connected on the side of the direct cooling plate 32 close to the opening of the cabinet 1. The refrigerant pipeline interface 2113 is arranged above or below the return air outlet 2111, so that the refrigerant pipeline 25 can be extended to one side to form a parallel branch 2512 connected to the direct cooling plate 32, which facilitates the arrangement of the refrigerant pipeline 25.

[0078] In some embodiments of the present application, Figure 6 and Figure 9 As shown, the refrigerant shutoff valve 23 is disposed on the front side of the housing 21, corresponding to the refrigerant pipeline interface 2113. The refrigerant shutoff valve 23 may include a first connector 231 and a second connector 232. The first connector 231 extends through the refrigerant pipeline interface 2113 and is connected to the refrigeration unit 22 via the internal pipeline 252. The second connector 232 is used to connect to the external pipeline 251, and the second connector 232 extends toward the outside of the housing 21. The second connector 232 is vertically arranged. The refrigerant shutoff valve 23 is disposed on the front side of the housing 21, and the second connector 232 extends toward the outside of the housing 21. This reduces steric resistance around the second connector 232 and facilitates connection between the second connector 232 and the external pipeline 251. Furthermore, the vertical arrangement of the second connector 232 aligns the extension direction of the second connector 232 with the portion of the external pipeline 251 that connects to the second connector 232, further facilitating connection of the external pipeline 251 to the second connector 232.

[0079] like Figure 6 、 Figure 9 as well as Figure 10As shown, in some embodiments of the present application, the refrigerant shut-off valve 23 includes a refrigerant outflow shut-off valve 231 and a refrigerant inflow shut-off valve 232. The refrigerant outflow shut-off valve 231 is provided in the first interface 21131, and the refrigerant inflow shut-off valve 232 is provided in the second interface 21132. The refrigerant inflow shut-off valve 232 and the refrigerant outflow shut-off valve 231 can be connected to different external pipelines 251 to form a refrigerant circulation loop with the refrigeration unit 22 and the direct cooling plate assembly 3. The first interface 21131 can provide a certain guiding and limiting effect on the refrigerant outflow shut-off valve 231, and the second interface 21132 can provide a certain guiding and limiting effect on the refrigerant inflow shut-off valve 232, thereby ensuring the stability of the unit pipeline installation.

[0080] like Figure 9 and Figure 10 As shown, in some embodiments of the present application, the refrigerant pipeline interface 2113 is arranged above the return air port 2111. The refrigerant pipeline interface 2113 is configured as a through groove extending downward from the top of the front side of the shell 21. The first joint portion 231 is passed through the through groove and extends into the shell 21. Generally, the diameter of the refrigerant pipeline interface 2113 is generally equivalent to the outer diameter of the refrigerant stop valve 23, and it is difficult to directly insert the refrigerant stop valve 23 into the refrigerant pipeline interface 2113. The present application sets the refrigerant pipeline interface 2113 as a channel connecting the upper end of the panel 211, so that when the refrigerant stop valve 23 is installed, the first joint portion 231 of the refrigerant stop valve 23 can slide from the notch of the through groove to the bottom position of the groove, which is convenient for positioning the refrigerant stop valve 23.

[0082] In some embodiments of the present application, Figure 5 and Figure 11 As shown, connecting parts 233 are respectively provided on both sides of the first joint part 231, a first mounting hole (not shown in the figure) is provided on the connecting part 233, and a second mounting hole (not shown in the figure) is provided on the panel 211. The first mounting hole and the second mounting hole are correspondingly arranged, and screws are passed through the first mounting hole and the second mounting hole to fix the refrigerant shut-off valve 23 on the panel 211.

[0083] In some embodiments, the refrigerant stop valve 23 is configured as a two-stage sealing stop valve to ensure the sealing performance of the refrigerant pipeline 25.

[0084] like Figure 10As shown, the front side of the housing 21 is also provided with an electrical interface 2114. The electrical interface 2114 is located on one side of the return air inlet 2111 in the height direction, while the refrigerant pipeline interface 2113 is located on the other side of the return air inlet 2111 in the height direction. In this way, the electrical connection circuits and refrigerant pipelines 25 of the vertical direct-cooling air conditioner 2 are arranged separately, located on either side of the return air inlet 2111 in the direction in which they extend. This reduces the mutual influence between the two circuit layouts and facilitates the layout of the electrical connection circuits and refrigerant pipelines 25.

[0085] In some embodiments of the present application, Figure 8 As shown, the electrical interface 2114 is located below the return air port 2111, and the refrigerant pipe interface 2113 is located above the return air port 2111. This allows the refrigerant shutoff valve 23 to extend above the housing 21 without being affected by the installation position. This also leaves sufficient space above the housing for the external pipes 251, facilitating their layout.

[0086] like Figure 7 As shown, the refrigeration unit 22 further includes an electric control box 225 , which is disposed in the housing 21 and opposite to the electrical interface 2114 .

[0087] In some embodiments of the present application, Figures 5 to 7 、 Figure 9 As shown, the vertical direct-cooling air conditioner 2 also includes a plug mounting plate 24. This plate is located outside the panel 214. Multiple electrical plugs 241 are mounted on this plate, which are inserted into the electrical interface 2114. These plugs 241 can include power connectors, display connectors, and host computer connectors. The integration of these multiple plugs 241 into the plate allows for easy installation and removal, facilitating installation and maintenance.

[0088] In some embodiments, the electrical plug 241 may be an aviation plug. Aviation plugs are generally made of high-temperature heat-resistant materials and can operate stably in high-temperature environments. Aviation plugs also provide stable and reliable connections that are not easily loosened or removed, ensuring stable power transmission.

[0089] In some embodiments of the present application, Figure 5 and Figure 9 As shown, a handle 218 is further provided on the front side of the housing 21. There are at least a plurality of handles 218, which are respectively provided on opposite sides of the return air outlet 2111 in pairs, so as to facilitate the movement of the vertical direct cooling air conditioner 2.

[0090] In some embodiments of the present application, Figure 5 and Figure 8As shown, the housing 21 is also provided with a mounting base 219. The mounting base 219 is provided on the front side and / or the bottom of the housing 21. Multiple mounting bases 219 are provided, and the mounting bases 219 are arranged in pairs opposite each other to secure the housing 21 to the cabinet 1, thereby improving the connection stability between the vertical direct-cooling air conditioner 2 and the cabinet 1.

[0091] In summary, the present application reduces the spatial steric resistance around the second joint part by extending the second joint part of the refrigerant stop valve toward the outside of the shell, thereby facilitating the connection of the second joint part with the external refrigerant pipeline. In addition, the second joint part is vertically arranged and protrudes from the top of the shell. The extension direction of the second joint part is consistent with the extension direction of the part connected to the second joint part on the external refrigerant pipeline, further facilitating the connection of the external refrigerant pipeline to the second joint part. The refrigerant pipeline interface is arranged above the return air outlet and is configured as a groove body at the upper end of the connecting panel, so that when the refrigerant stop valve is installed, the refrigerant stop valve can slide into the groove body from the opening of the groove body, thereby improving the convenience of installing the refrigerant stop valve.
