The cooling plate is mounted on the battery rack, and the battery is supported on the cooling plate. The battery rack is used to support the cooling plate and the battery supported on the cooling plate. The cooling plate is connected to the cooling pipes, which are used to deliver coolant into the cooling plate. The cooling plate is used to cool the battery.

[0003] However, since battery racks typically have multiple rows and columns of batteries, they also have multiple rows and columns of cooling plates. The cooling pipes need to be connected to these multiple rows and columns of cooling plates, which requires the cooling pipes to include a large number of cooling branch pipes. This results in a complex and long overall layout of the cooling pipes, leading to higher costs and greater space requirements for the cooling pipes. Consequently, the cooling devices are more expensive, occupy more space in the energy storage equipment, and are more difficult to install within the energy storage equipment.

Detailed Implementation

[0037] To enable those skilled in the art to better understand the technical solution of the present invention, the battery cooling support device and energy storage device provided by the present invention will be described in detail below with reference to the accompanying drawings.

[0038] like Figure 1 As shown, this embodiment of the invention provides a battery cooling support device, including a support frame 1 and a cooling structure. The support frame 1 is used to support multiple batteries and is provided with a cooling channel. The cooling channel is used to communicate with a cooling medium source 4 and with the outside. The cooling structure includes a cooling component 21, which is disposed on the support frame 1 and communicates with the cooling channel to communicate with the cooling medium source 4 so that the cooling medium can enter and be discharged. The cooling component 21 is used to cool the battery from the outside.

[0039] The battery cooling support device provided in this embodiment of the invention, by setting a cooling component 21 on the support frame 1 and connecting the cooling component 21 with the cooling channel of the support frame 1, allows the cooling component 21 to be connected to the cooling medium source 4 through the cooling channel. This enables the cooling medium from the cooling medium source 4 to enter the cooling component 21 through the cooling channel, thereby cooling the battery on the support frame 1 with the help of the cooling component 21. In this way, the support frame 1 can not only support the battery, but also be used as part of the pipeline for delivering the cooling medium to the cooling component 21, realizing the reuse of the support frame 1. Compared with the prior art, the cooling medium can be delivered to the cooling component 21 through the cooling channel of the support frame 1, eliminating the need for a separate pipeline for delivering the cooling medium to the cooling component 21. In other words, it can save the separate pipeline for delivering the cooling medium to the cooling component 21, thereby reducing the cost of the cooling structure, reducing the space occupied by the cooling structure in the energy storage device, increasing the redundant space of the energy storage device, and facilitating the arrangement of the cooling structure within the energy storage device.

[0040] In practical applications, the support frame 1 can support multiple batteries, which can be placed vertically at intervals on the support frame 1. The cooling medium from the cooling medium source 4 can first enter the cooling channel of the support frame 1, and then enter the cooling component 21, which is set on the support frame 1 and connected to the cooling channel, through the cooling channel of the support frame 1. Thus, the cooling component 21 can cool the battery from the outside. The cooling medium that has heated up after heat exchange with the battery can enter the cooling channel of the support frame 1 through the cooling component 21, and then be discharged to the outside through the cooling channel of the support frame 1. Thus, the low-temperature cooling medium can continuously enter the cooling component 21 to cool the battery.

[0041] Optionally, the cooling medium may include coolant.

[0042] Optionally, the cooling medium source 4 may include a liquid cooling source.

[0043] In practical applications, the liquid cooling source can cool the heated cooling medium, reducing its temperature to form a cooling medium. One end of the cooling channel of the support frame 1, which is connected to the outside, can be connected to the cooling medium source 4. Thus, the heated cooling medium discharged from the cooling assembly 21 can first be discharged into the cooling channel of the support frame 1, and then through the cooling channel of the support frame 1 to the cooling medium source 4. The cooling medium source 4 cools the heated cooling medium to form a cooling medium, which is then transported through the cooling medium source 4 to the cooling channel of the support frame 1, and then through the cooling channel of the support frame 1 into the cooling assembly 21 to cool the battery, thereby enabling the cooling medium to circulate.

[0044] like Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the support frame 1 may include an inlet frame 11 and an outlet frame 12, which are arranged opposite to each other to support the battery from opposite sides. The inlet frame 11 is provided with an inlet channel, and the outlet frame 12 is provided with an outlet channel. The cooling channel includes an inlet channel and an outlet channel. The inlet channel is used to communicate with the cooling medium source 4, and the outlet channel is connected to the outside. The cooling assembly 21 is connected to the inlet frame 11 and the outlet frame 12 respectively, and communicates with the inlet channel and the outlet channel respectively.

[0045] In practical applications, the inlet frame 11 can support the battery from one side bottom, and the outlet frame 12, which is opposite to the inlet frame 11, can support the battery from the other side bottom, thus supporting the battery from opposite sides. The cooling medium from the cooling medium source 4 can first enter the inlet channel of the inlet frame 11, and then enter the cooling component 21 connected to the inlet channel through the inlet channel of the inlet frame 11. Thus, the battery can be cooled by the cooling component 21. After the cooling medium has heated up due to heat exchange with the battery, it can then enter the outlet channel of the outlet frame 12 through the cooling component 21, and then be discharged to the outside through the outlet channel of the outlet frame 12.

[0046] like Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the entrance frame 11 may include a plurality of entrance horizontal columns 111 and a plurality of entrance vertical columns 112. The plurality of entrance vertical columns 112 are arranged side by side with intervals, and the plurality of entrance horizontal columns 111 are arranged with intervals along the extending direction of the entrance vertical columns 112. Each entrance horizontal column 111 and each entrance vertical column 112 is a hollow structure, and each entrance horizontal column 111 is connected to the plurality of entrance vertical columns 112 to form an entrance channel; the exit frame 12 may include a plurality of exit horizontal columns 121 and a plurality of exit vertical columns 122. The vertical column 122 is arranged side by side with multiple exiting vertical columns 122 spaced apart. Multiple exiting horizontal columns 121 are arranged spaced apart along the extension direction of the exiting vertical columns 122. Each exiting horizontal column 121 and each exiting vertical column 122 is a hollow structure, and each exiting horizontal column 121 is connected to multiple exiting vertical columns 122 to form an exiting channel. Multiple entering horizontal columns 111 and multiple exiting horizontal columns 121 are arranged one-to-one. The corresponding entering horizontal columns 111 and exiting horizontal columns 121 are used to support the battery from the opposite sides of the battery.

[0047] like Figure 1 and Figure 2As shown, the entrance frame 11 may include 5 entrance horizontal columns 111 and 2 entrance vertical columns 112. The 5 entrance horizontal columns 111 and 2 entrance vertical columns 112 are all hollow structures. The 2 entrance vertical columns 112 are arranged side by side with intervals. The 5 entrance horizontal columns 111 are arranged at intervals along the extension direction of the entrance vertical columns 112. The two ends of each entrance horizontal column 111 are respectively connected to the 2 entrance vertical columns 112, so that the 2 entrance vertical columns 112 can support all the entrance horizontal columns 111 and allow the cooling medium entering one entrance horizontal column 111 and / or one entrance vertical column 112 to enter all the entrance horizontal columns 111 and entrance vertical columns 112, thereby enabling the 5 entrance horizontal columns 111 and 2 entrance vertical columns 112 to form an entrance channel. The outlet frame 12 may include five outlet horizontal columns 121 and two outlet vertical columns 122. The five outlet horizontal columns 121 and the two outlet vertical columns 122 are hollow structures. The two outlet vertical columns 122 are arranged side by side with intervals. The five outlet horizontal columns 121 are arranged at intervals along the extension direction of the outlet vertical columns 122. The two ends of each outlet horizontal column 121 are connected to the two outlet vertical columns 122 respectively, so that the two outlet vertical columns 122 can support all the outlet horizontal columns 121 and allow the cooling medium entering one outlet horizontal column 121 and / or one outlet vertical column 122 to enter all the outlet horizontal columns 121 and outlet vertical columns 122, thereby enabling the five outlet horizontal columns 121 and the two outlet vertical columns 122 to form an outlet channel. Five inlet crossbars 111 and five outlet crossbars 121 are set one-to-one. One inlet crossbar 111 and one outlet crossbar 121 can support one battery from the bottom of the opposite sides of the battery. The five inlet crossbars 111 and five outlet crossbars 121 can support five batteries.

[0048] However, the number of ingress side horizontal columns 111 and ingress side vertical columns 112 included in the ingress side frame 11 is not limited to this, and the number of outgress side horizontal columns 121 and outgress side vertical columns 122 included in the outgress side frame 12 is not limited to this.

[0049] like Figure 1 As shown, in one embodiment of the present invention, the inlet vertical column 112 can be connected to the cooling medium source 4, and the outlet vertical column 122 can be connected to the outside.

[0050] In other words, the inlet channel of the inlet frame 11 can be connected to the cooling medium source 4 through the inlet vertical column 112. The cooling medium of the cooling medium source 4 can first enter the inlet vertical column 112, and then enter the cooling component 21 and / or all the inlet horizontal columns 111 through the inlet vertical column 112. The outlet channel of the outlet frame 12 can be connected to the cooling medium source 4 through the outlet vertical column 122. The cooling medium that has been heated by heat exchange with the battery can first be discharged to the outlet vertical column 122, and then discharged to the cooling medium source 4 through the outlet vertical column 122.

[0051] Optionally, multiple inlet vertical columns 112 can be connected to the cooling medium source 4 respectively, and multiple outlet vertical columns 122 can be connected to the outside world respectively.

[0052] For example, there are two inlet vertical columns 112, which can be connected to the cooling medium source 4 respectively. There are also two outlet vertical columns 122, which can be connected to the cooling medium source 4 respectively. In this way, the cooling medium from the cooling medium source 4 can enter the two inlet vertical columns 112 respectively. After the cooling medium is heated by heat exchange with the battery, it can be discharged to the cooling medium source 4 through the two outlet vertical columns 122 respectively. This can increase the flow rate of the cooling medium entering the inlet frame 11 and the flow rate of the heated cooling medium discharged through the outlet frame 12, thereby increasing the circulation flow rate of the cooling medium in the battery cooling support device and thus improving the cooling efficiency of the battery.

[0053] In one embodiment of the present invention, the support frame 1 can be made of a corrosion-resistant material. That is, the materials of the inlet horizontal column 111, the inlet vertical column 112, the outlet horizontal column 121, and the outlet vertical column 122 can all be corrosion-resistant materials, which can reduce the corrosion of the support frame 1 by the cooling medium and improve the service life and stability of the support frame 1.

[0054] Optionally, the inlet horizontal column 111, the inlet vertical column 112, the outlet horizontal column 121, and the outlet vertical column 122 can all be cylindrical.

[0055] Optionally, the inlet horizontal column 111 and the inlet vertical column 112 can be welded together, and the outlet horizontal column 121 and the outlet vertical column 122 can be welded together. This can improve the connection stability of the support frame 1 and reduce the possibility of cooling medium leaking out of the support frame 1.

[0056] like Figure 1 and Figure 3 As shown, in one embodiment of the present invention, the cooling assembly 21 may include a first side cooling component 211 and / or a second side cooling component 212. The first side cooling component 211 is disposed between the opposite inlet side horizontal column 111 and outlet side horizontal column 121, and is connected to the inlet side horizontal column 111 and outlet side horizontal column 121 respectively. The second side cooling component 212 is disposed between the opposite inlet side vertical column 112 and outlet side vertical column 122, and is connected to the inlet side vertical column 112 and outlet side vertical column 122 respectively.

[0057] In practical applications, the battery can have six sides, namely a top side, a bottom side, a front side, a rear side, a left side, and a right side. The bottom side of the battery can contact the opposing inlet cross post 111 and outlet cross post 121. The opposing inlet cross post 111 and outlet cross post 121 can support the battery from opposite sides of the bottom side. The top side and bottom side of the battery can be two opposite sides of the battery. A first... The first side cooling element 211 is connected to the inlet cross column 111 and the outlet cross column 121 respectively. The cooling medium can enter the first side cooling element 211 from the inlet cross column 111 and then be discharged to the outlet cross column 121 through the first side cooling element 211. Thus, the first side cooling element 211 can be used to cool the lower battery from the top side of the lower battery among two adjacent batteries, and to cool the upper battery from the bottom side of the upper battery among two adjacent batteries.

[0058] The left and right sides of the battery can be opposite sides of the battery, and can be perpendicular to the bottom and top sides of the battery. The left side of the battery can face the inlet frame 11, and the right side of the battery can face the outlet frame 12. The front and rear sides of the battery can be opposite sides of the battery, and can be perpendicular to the bottom and top sides of the battery, and can be perpendicular to the left and right sides of the battery. By setting a second side cooling element 212 between the opposite inlet vertical column 112 and outlet vertical column 122, and connecting the second side cooling element 212 to both the inlet vertical column 112 and the outlet vertical column 122, the cooling medium can enter the second side cooling element 212 from the inlet vertical column 112 and then be discharged to the outlet horizontal column 121 through the second side cooling element 212. Thus, the battery can be cooled from the rear side using the second side cooling element 212.

[0059] By using the first side cooling element 211 and the second side cooling element 212 to cool the battery simultaneously, the battery can be cooled from different sides at the same time, thereby improving the cooling efficiency of the battery and slowing down the spread of disaster in the event of a battery failure.

[0060] like Figure 1 and Figure 3 As shown, in one embodiment of the present invention, the cooling assembly 21 may further include an inlet cooling component 213 and / or an outlet cooling component 214. The inlet cooling component 213 is disposed between two adjacent inlet crossbars 111 and is connected to the two adjacent inlet crossbars 111 respectively. The outlet cooling component 214 is disposed between two adjacent outlet crossbars 121 and is connected to the two adjacent outlet crossbars 121 respectively.

[0061] By providing an inlet cooling element 213 between two adjacent inlet crossbars 111 and connecting the inlet cooling element 213 to the two adjacent inlet crossbars 111 respectively, the cooling medium can enter the inlet cooling element 213 from one of the two adjacent inlet crossbars 111 and then be discharged to the other of the two adjacent inlet crossbars 111 through the inlet cooling element 213. Thus, the battery can be cooled from the left side of the battery facing the inlet frame 11 with the help of the inlet cooling element 213. By setting an outlet cooling element 214 between two adjacent outlet horizontal columns 121 and connecting the outlet cooling element 214 to the two adjacent outlet horizontal columns 121 respectively, the cooling medium can enter and exit the outlet cooling element 214 from one of the two adjacent outlet horizontal columns 121, and then be discharged to the other outlet horizontal column 121 of the two adjacent outlet horizontal columns 121 through the outlet cooling element 214. Thus, the battery can be cooled from the left side of the battery facing the outlet frame 12 with the help of the outlet cooling element 214.

[0062] By simultaneously cooling the battery with the first side cooling component 211, the second side cooling component 212, the inlet side cooling component 213, and the outlet side cooling component 214, the battery can be cooled from more different sides at the same time, thereby further improving the cooling efficiency of the battery and further mitigating the spread of disaster in the event of a battery failure.

[0063] In one embodiment of the present invention, the cooling component 21 is capable of expanding and fitting into the battery while filled with a cooling medium.

[0064] In practical applications, the cooling component 21 does not support the battery. When the cooling component 21 is filled with cooling medium, it can expand to fit against the battery, and when it is not filled with cooling medium, it can contract. By enabling the cooling component 21 to expand to fit against the battery when filled with cooling medium, the cooling efficiency of the battery can be improved.

[0065] Optionally, the cooling component 21 may be elastic. This allows the cooling component 21 to expand when filled with cooling medium and contract when not filled with cooling medium, and the elasticity of the cooling component 21 also allows it to act as a buffer.

[0066] Optionally, the cooling component 21 can be a heat-conducting airbag plate.

[0067] Optionally, the heat-conducting airbag plate can be made of a composite material of silicone and rubber with excellent thermal conductivity. This material has sufficient elasticity and ductility to maintain a high degree of expansion while withstanding strong pressure, thus allowing it to fit well with the battery, cool the battery, and fill the gap between two adjacent batteries effectively.

[0068] like Figure 1 and Figure 4 As shown, in one embodiment of the present invention, the cooling structure may further include an inlet pipe 22 and an outlet pipe 23. The inlet pipe 22 is connected to the inlet side vertical column 112 and is used to connect to the cooling medium source 4 to deliver the cooling medium to the inlet side vertical column 112. The outlet pipe 23 is connected to the outlet side vertical column 122 and is connected to the outside to discharge the cooling medium. One of the connection positions of the inlet pipe 22 and the inlet side vertical column 112 and the outlet pipe 23 and the outlet side vertical column 122 is located at the top of the support frame 1, and the other is located at the bottom of the support frame 1.

[0069] For example, the connection between the inlet pipe 22 and the inlet side column 112 can be located at the top of the inlet side column 112, and the connection between the outlet pipe 23 and the outlet side column 122 can be located at the bottom of the outlet side column 122. The cooling medium of the cooling medium source 4 can enter the inlet side channel of the inlet side frame 11 through the inlet pipe 22 from the top of the inlet side column 112, and can flow downward into multiple inlet side horizontal columns 111 and multiple cooling components 21. The heated cooling medium discharged from the multiple cooling components 21 can be discharged from the bottom of the outlet side column 122 to the outlet pipe 23, and then discharged to the cooling medium source 4 through the outlet pipe 23.

[0070] like Figure 1 and Figure 4 As shown, in one embodiment of the present invention, the inlet pipe 22 may include a main inlet pipe 221 and a connecting inlet pipe 222. The main inlet pipe 221 is used to communicate with the cooling medium source 4 and is connected to the inlet side column 112 through the connecting inlet pipe 222; and / or, the outlet pipe 23 may include a main outlet pipe 231 and a connecting outlet pipe 232. The main outlet pipe 231 is connected to the outside and is connected to the outlet side column 122 through the connecting outlet pipe 232.

[0071] In practical applications, the cooling medium from the cooling medium source 4 can first enter the main inlet pipe 221, then enter the connecting inlet pipe 222 through the main inlet pipe 221, and then enter the inlet side column 112 through the connecting inlet pipe 222. The heated cooling medium discharged from the outlet side column 122 can first enter the connecting outlet pipe 232, then be discharged to the main outlet pipe 231 through the connecting outlet pipe 232, and then be discharged to the cooling medium source 4 through the main outlet pipe 231.

[0072] Optionally, both the main inlet pipe 221 and the main outlet pipe 231 can be made of corrosion-resistant materials. This can reduce the corrosion of the main inlet pipe 221 and the main outlet pipe 231 by the cooling medium, and improve the service life and operational stability of the main inlet pipe 221 and the main outlet pipe 231.

[0073] Optionally, both the inlet pipe 222 and the outlet pipe 232 can be flexible hoses. This improves the flexibility of the inlet pipe 222 and the outlet pipe 232, making it easier for the inlet pipe 222 to connect to the main inlet pipe 221 and the inlet side column 112 respectively, and for the outlet pipe 232 to connect to the main outlet pipe 231 and the outlet side column 122 respectively.

[0074] like Figure 1 and Figure 4 As shown, in one embodiment of the present invention, the number of inlet pipes 22 and / or the number of outlet pipes 23 can be multiple, with multiple inlet pipes 22 corresponding to and connected to multiple inlet side vertical columns 112, and multiple outlet pipes 23 corresponding to and connected to multiple outlet side vertical columns 122.

[0075] In this way, the multiple inlet vertical columns 112 can be connected to the cooling medium source 4 through the corresponding inlet pipes 22, and / or the multiple outlet vertical columns 122 can be connected to the outside through the corresponding outlet pipes 23.

[0076] like Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the battery cooling support device may further include a support block 3. The top and bottom ends of the inlet vertical column 112 and the top and bottom ends of the outlet vertical column 122 are all provided with support blocks 3. The radial dimension of the support block 3 is greater than the radial dimension of the inlet vertical column 112 and the radial dimension of the outlet vertical column 122.

[0077] The inlet-side vertical column 112 can be fixed in the energy storage device by support blocks 3 set at its top and bottom. By making the radial dimension of the support block 3 larger than the radial dimension of the inlet-side vertical column 112, the stability of the inlet-side vertical column 112 fixed in the energy storage device can be improved. The outlet-side vertical column 122 can be fixed in the energy storage device by support blocks 3 set at its top and bottom. By making the radial dimension of the support block 3 larger than the radial dimension of the outlet-side vertical column 122, the stability of the outlet-side vertical column 122 fixed in the energy storage device can be improved.

[0078] In one embodiment of the present invention, the radial dimension of the inlet horizontal column 111 can be greater than the radial dimension of the inlet vertical column 112, and the radial dimension of the outlet horizontal column 121 can be greater than the radial dimension of the outlet vertical column 122.

[0079] This allows the inlet horizontal column 111 to protrude relative to the inlet vertical column 112, and the outlet horizontal column 121 to protrude relative to the outlet vertical column 122. Thus, the battery can be supported from the bottom of opposite sides by means of the protruding portions of the inlet horizontal column 111 relative to the inlet vertical column 112 and the outlet horizontal column 121 relative to the outlet vertical column 122.

[0080] Optionally, both the inlet horizontal column 111 and the outlet horizontal column 121 may include a connecting portion and a supporting portion. The connecting portion of the inlet horizontal column 111 is connected to the inlet vertical column 112, and the supporting portion of the inlet horizontal column 111 protrudes towards the outlet frame 12 relative to the connecting portion of the inlet horizontal column 111. The connecting portion of the outlet horizontal column 121 is connected to the outlet vertical column 122, and the supporting portion of the outlet horizontal column 121 protrudes towards the inlet frame 11 relative to the connecting portion of the outlet horizontal column 121. The supporting portions of the inlet horizontal column 111 and the outlet horizontal column 121 are used to jointly support the battery. That is, both the inlet horizontal column 111 and the outlet horizontal column 121 may be L-shaped, thereby enabling the battery to be supported from the bottom of opposite sides of the battery by means of the inlet horizontal column 111 and the outlet horizontal column 121.

[0081] like Figure 1 and Figure 3 As shown, in one embodiment of the present invention, the opposite sides of the cooling assembly 21 are connected to the support frame 1 via adapter pipes 24 and communicate with the cooling channel.

[0082] In practical applications, the cooling medium in the cooling channel can enter the cooling assembly 21 through the adapter pipe 24 located on one side of the cooling assembly 21, and the cooling medium discharged from the cooling assembly 21 can be discharged through the adapter pipe 24 on the other side of the cooling assembly 21.

[0083] Optionally, each of the opposite sides of the cooling assembly 21 may be provided with multiple adapter pipes 24. This can increase the flow rate of the cooling medium entering the cooling assembly 21 and the flow rate of the heated cooling medium exiting the cooling assembly 21, thereby increasing the circulation flow rate of the cooling medium in the cooling assembly 21 and thus improving the cooling efficiency of the battery.

[0084] like Figure 1 , Figure 3 and Figure 5As shown, for example, one side of the first side cooling component 211 can be connected to the inlet cross column 111 through two adapter pipes 24, and the other side of the first side cooling component 211 can be connected to the outlet cross column 121 through two other adapter pipes 24. In this way, the cooling medium in the inlet cross column 111 can enter the first side cooling component 211 from one side through the two adapter pipes 24, and the cooling medium discharged from the first side cooling component 211 can be discharged from the other side of the first side cooling component 211 to the outlet cross column 121 through the two other adapter pipes 24.

[0085] like Figure 1 , Figure 3 and Figure 6 As shown, for example, one side of the left cooling component can be connected to one of the two adjacent inlet crossbars 111 via two adapter pipes 24, and the other side of the left cooling component can be connected to the other of the two adjacent inlet crossbars 111 via two other adapter pipes 24. In this way, the cooling medium in one of the two adjacent inlet crossbars 111 can enter the left cooling component from one side of the left cooling component via two adapter pipes 24, and the cooling medium discharged from the left cooling component can be discharged from the other side of the left cooling component to the other of the two adjacent inlet crossbars 111 via two other adapter pipes 24.

[0086] like Figure 1 , Figure 3 and Figure 7 As shown, for example, one side of the second side cooling element 212 can be connected to the inlet column 112 through two adapter pipes 24, and the other side of the second side cooling element 212 can be connected to the outlet column 122 through two other adapter pipes 24. In this way, the cooling medium in the inlet column 112 can enter the second side cooling element 212 from one side through the two adapter pipes 24, and the cooling medium discharged from the second side cooling element 212 can be discharged from the other side of the second side cooling element 212 to the outlet column 122 through the two other adapter pipes 24.

[0087] Optionally, the adapter pipe 24 can be a single-threaded PVC pipe. The threaded end of the single-threaded PVC pipe can be connected to the metal support frame 1, and the unthreaded end can be connected to the heat-conducting airbag plate by heat shrink adhesive.

[0088] This invention also provides an energy storage device, including an energy storage cavity (not shown in the figure) and a battery cooling support device as provided in this invention embodiment. The battery cooling support device is disposed in the energy storage cavity and is used to support and cool the battery.

[0089] The energy storage device provided in this embodiment of the invention supports and cools the battery by setting a battery cooling support device, as provided in this embodiment of the invention, inside the energy storage cavity. This reduces the cost of the cooling structure, reduces the space occupied by the cooling structure in the energy storage device, increases the redundant space of the energy storage device, and facilitates the arrangement of the cooling structure inside the energy storage device.

[0090] like Figure 1 As shown, optionally, the energy storage device may also include a cooling medium source 4, which is disposed in the energy storage cavity and connected to the battery cooling support device.

[0091] Optionally, the cooling medium source 4 can be a Tongfei LCI-300CR.

[0092] like Figure 1 As shown, optionally, the energy storage device may also include a medium source inlet pipe 41 and a medium source return pipe 42. The medium source inlet pipe 41 is connected to the cooling medium source 4 and the inlet pipe 22, respectively, and the medium source return pipe 42 is connected to the cooling medium source 4 and the outlet pipe 23, respectively.

[0093] In practical applications, the cooling medium of the cooling medium source 4 can first enter the medium source inlet pipe 41, and then enter the inlet pipe 22 through the medium source inlet pipe 41. The heated cooling medium can be discharged through the outlet pipe 23 to the medium source return pipe 42, and then flow back to the cooling medium source 4 through the medium source return pipe 42.

[0094] In summary, the battery cooling support device and energy storage device provided by the embodiments of the present invention can reduce the cost of the cooling structure, reduce the space occupied by the cooling structure in the energy storage device, increase the redundancy space of the energy storage device, and facilitate the arrangement of the cooling structure in the energy storage device.

For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
