[0032] like Figure 1-Figure 2 As shown, the energy storage container system layout structure includes:

[0033] A container 1 and a cooling device 5 arranged on the outer side wall of the container 1;

[0037] The top heat dissipation duct 72 is arranged at the top of the container 1, the return air port end 721 of the top heat dissipation duct 72 is connected with the return air port 51 of the cooling device 5, and the air inlet pipe body of the top heat dissipation duct 72 is located at the inner top of the battery compartment 2; the bottom wall and / or side wall of the air inlet pipe body are provided with a hot air inlet;

[0038] The air inlet end 711 of the bottom heat dissipation air duct 71 is provided with a fan 8, and the fan 8 is used to transport the cold air provided by the cooling device 5 to the fire fighting room 4 to the inside of the bottom heat dissipation air duct 71;

[0039] The cold air from the cold air outlet 7121 passes through the battery compartment 2 and then flows back to the top heat dissipation duct 72 through the hot air inlet.

[0040] In the application, the layout structure of the energy storage container system mainly includes: container 1, battery compartment 2 (built-in battery cluster 21), electrical compartment 6, fire protection room 4, liquid cooling unit 3, cooling device 5, bottom heat dissipation duct 71 and top heat dissipation duct 72, etc.

[0041] The battery compartment 2 and the electrical compartment 6 are completely isolated from each other by an insulation board wall 61, the battery compartment 2 and the fire room 4 are isolated from each other by an insulation board wall 61, the electrical compartment 6 and the fire room 4 are isolated from each other by an insulation board wall 61, the liquid cooling unit 3 is isolated from the battery compartment 2 and the fire room 4 by an insulation board wall 61, the liquid cooling unit 3 is connected to the liquid cooling plate through a liquid cooling pipeline, and is used to take away the heat of the battery cells in the battery pack of the battery cluster; ventilation holes are provided on the insulation board wall 61 on the right side of the electrical compartment 6 and on the top sealing plate, which are used for the circulation of cold air delivered by the cooling device 5; the heat dissipation duct structure 7 is arranged in the fire room 4 and the battery compartment 2, and the heat dissipation duct structure 7 is divided into a bottom heat dissipation duct 71 and a top heat dissipation duct 72.

[0042] Furthermore, a fan 8 is installed on the bottom heat dissipation duct 71, which can transport the cold air delivered by the cooling device 5 to the inside of the bottom heat dissipation duct 71. The bottom heat dissipation duct 71 is provided with ventilation holes at certain intervals to evenly transport the cold air to each battery cluster 21, thereby dissipating the heat of the battery cluster 21; one end of the top heat dissipation duct structure 72 is connected to the electrical compartment 6, and the other end is connected to the return air outlet 51 of the cooling device 5; the cold air in the top enters the internal duct of the top heat dissipation structure from the top, thereby realizing the cold air circulation.

[0043] See also Figure 1 During the operation of the cooling device 5, a first cooling circulation air path can be formed between the electrical compartment 6 and the fire fighting room 4, and the battery compartment 2, the cooling device 5 and the fire fighting room 4 are connected through the bottom heat dissipation air duct 71 and the top heat dissipation air duct 72, so as to form a second cooling circulation air path.

[0044] Among them, the heat dissipation method of the equipment in the electrical cabin 6 is as follows: the cold air delivered by the cooling device 5, a part of which enters the electrical cabin 6 through the partition wall ventilation holes 611 on the insulation board wall 61 between the electrical cabin 6 and the fire fighting room 4, and after the cold air passes through the equipment inside the electrical cabin 6, it takes away the heat of the equipment during operation, thereby realizing the heat dissipation of the equipment in the electrical cabin 6; after the cold air passes through the top sealing plate ventilation hole 612, it enters the fire fighting room 4, thus forming a self-circulation of cold air between the electrical cabin 6 and the fire fighting room 4.

[0045] The energy storage container system layout structure provided by the present invention can evenly deliver the cold air output by the cooling device 5 to the battery compartment 2, the electrical compartment 6 and the fire room 4, so as to cool the battery cluster 21 in the battery compartment 2 while also dissipating heat and cooling the electronic equipment in the electrical compartment 6 and the fire room 4; the present invention can solve the heat dissipation problem of the battery compartment 2 and the electrical compartment 6, and evenly deliver the cold air to the battery compartment 2 and the electrical compartment 6 through reasonable ventilation holes on the heat dissipation duct, thereby improving the heat exchange efficiency; in addition, the present invention can only use one set of cooling devices 5 for cooling, reducing the cost of the heat dissipation system; by arranging the heat dissipation duct structure 7, rapid and balanced heat dissipation is achieved, and the service life of the energy storage system is also improved as a whole.

[0046] In one embodiment, multiple battery clusters 21 are arranged inside the battery compartment 2 to form an array, and gaps for cooling air flow are arranged between adjacent battery clusters 21. This arrangement can make the heat dissipation of each battery cluster 21 in the battery compartment 2 more balanced.

[0047] See also Figure 3 In one embodiment, a plurality of cold air outlets 7121 may be provided at intervals of a first preset distance on the top and / or side walls of the air outlet pipe body; a plurality of hot air inlets may be provided at intervals of a second preset distance on the bottom wall and / or side walls of the air inlet pipe body.

[0048] Through this three-sided opening design, the amount of cold air entering the battery compartment 2 is dispersed and uniform in each area, which can evenly cool the battery cluster 21.

[0049] In one embodiment, the air outlet pipe body includes multiple first branch structures 712; the bottom wall and / or side wall of each first branch structure 712 is provided with a cold air outlet 7121; the air inlet pipe body includes multiple second branch structures; the bottom wall and / or side wall of each second branch structure is provided with a hot air inlet.

[0050] like Figure 3 As shown, taking the bottom heat dissipation duct 71 as an example, the bottom heat dissipation duct 71 can be composed of multiple sections of first branch structures 712 connected by bolts and fixed on the bottom plate of the container 1.

[0051] The first branch structure 712 has ventilation holes on the front, back and top. By opening the ventilation holes on three sides, cold air can be evenly delivered to the bottom of each battery cluster 21 and the gap space at the end; the cold air passes through the battery cluster 21 from bottom to top, takes away the heat generated by the battery cluster 21 when working, and finally gathers at the top.

[0052] In one embodiment, the return air outlet end 721 of the top heat dissipation air duct 72 and the return air outlet 51 of the cooling device 5 are both located in the fire protection room 4; the return air outlet end 721 of the top heat dissipation air duct 72 and the return air outlet 51 of the cooling device 5 are sealed at the connection point using an EPDM sealing strip 722.

[0053] In application, see Figure 1 and Figure 4 The return air outlet 51 of the cooling device 5 is connected to the return air outlet end 721 on the top heat dissipation duct 72 and is located in the fire fighting room, and an EPDM sealing strip 722 is pasted at the connecting point; this can not only effectively save the internal space of the energy storage container 1, but also effectively prevent hot air from entering the fire fighting room 4, thereby affecting the ambient temperature of the fire fighting room 4.

[0054] In one embodiment, the thermal insulation board wall 61 may be a rock wool board wall.

[0055] In one embodiment, the cross-sectional area of ​​the bottom heat dissipation air duct 71 gradually decreases along the extension direction of the internal air path; and the cross-sectional area of ​​the top heat dissipation air duct 72 gradually increases along the extension direction of the internal air path.

[0056] Such an arrangement can help improve the uniformity of the air volume at each location of the bottom heat dissipation duct 71 and the top heat dissipation duct 72, thereby making the heat dissipation inside the battery compartment 2 more balanced.
