The shell 410 of the battery cluster management module 400 is connected to the bracket mounting surface 310 of the bracket 300, so that the shell 410 is inclined relative to the first mounting wall 220, thereby increasing the heat distribution area inside the battery cluster management module 400 in the direction perpendicular to the first mounting wall 220, so that the heat distributed by the battery cluster management module 400 in the direction perpendicular to the first mounting wall 220 can be heat exchanged with the air with a lower temperature away from the first mounting wall 220, thereby enhancing the passive heat dissipation capability of the battery cluster management module 400 in the high-voltage control box, and the performance of the battery cluster management module 400 can also be improved.

[0037] For more information, see Figure 2 When the housing 410 is tilted at a preset angle, the spatial distribution of the components inside the battery cluster management module 400 will also be tilted synchronously, so that the heat generated by each component in the battery cluster management module 400 is also distributed in a direction perpendicular to the first installation wall 220 (i.e. Figure 2 Therefore, some components in the battery cluster management module 400 will be away from the first installation wall 220 and contact with the lower temperature gas that is also away from the first installation wall 220, and the cooling rate of these components will be improved.

[0039] For more information, see Figure 1 , Figure 2 , Figure 3 As shown, Figure 3 for Figure 1 A schematic diagram of the positional relationship between the battery cluster management module 400 and the box body 200 in FIG. 2 is shown in FIG. 3 .

As a preferred solution, the bracket 300 is provided with a heat dissipation hole 360, and the high-temperature gas in the mounting groove 340 can be directly exchanged with the lower-temperature gas in the accommodating cavity 210 through the heat dissipation hole 360, so as to facilitate heat exchange with the battery cluster management module 400; it should be noted that the heat dissipation hole 360 ​​can be provided in the first storage compartment 330, and can also be provided in the bracket 320.

[0040] For further information, please refer to Figure 2 and Figure 3 In some embodiments, the bracket 300 further includes a second storage bin connected to a side of the first storage bin 330 close to the first mounting wall 220 (ie, Figure 2 , Figure 3 The second receiving compartment is used to receive and install at least part of the electronic components 100.

Through the above solution, the electronic components 100 originally set on the first installation wall 220 can be set in the second storage compartment or the third storage compartment 350, so that the heat of the electronic components 100 partially gathered on the first installation wall 220 can be transferred to the second storage compartment or the third storage compartment 350, reducing the heat accumulation on the first installation wall 220, and dispersing the heat in the direction perpendicular to the first installation wall 220, thereby increasing the heat distribution in the high-voltage control box in the storage chamber 210; at least part of the electronic components installed in the second storage compartment and / or the third storage compartment 350 can be exposed to the lower temperature gas away from the side of the first installation wall, and the passive heat dissipation capacity of the part of the electronic components is further enhanced.

[0043] According to the above solution, the maximum distance in the box body 200 in the direction perpendicular to the first mounting wall 220 (i.e., the distance H between the top wall 240 and the first mounting wall 220) depends on the maximum height of each device in the accommodating cavity 210 relative to the first mounting wall 220 in the first direction (i.e., H 1 is less than H); then when H 2 Less than H 1 When the battery cluster management module 400 is connected to the first installation wall 220, the space of the electronic component 100 in the direction parallel to the first installation wall 220 can be used to avoid increasing the overall volume of the high-voltage control box. Figure 3 In some embodiments, since the electronic component 100 disposed on the first mounting wall 220 has H 1 , the battery cluster management module 400 can be completely accommodated in the direction parallel to the first installation wall 220 (i.e. Figure 3 space on the right side of the ).

[0044] For further information, please refer to Figure 3In some embodiments, the bracket 300 includes a bracket body 320 and a first accommodating chamber 330, the bracket body 320 is connected to the first mounting wall 220, and the side of the bracket body 320 facing away from the first mounting wall 220 has a bracket mounting surface 310, the first accommodating chamber 330 is connected to the bracket body 320 and defines a mounting groove 340 with the bracket mounting surface 310, and the housing 410 is located in the mounting groove 340; the bracket 300 also includes a third accommodating chamber 350, the third accommodating chamber 350 is connected to the side of the first accommodating chamber 330 close to the first mounting wall 220, and the third accommodating chamber 350 is used to accommodate and install at least part of the electronic components 100; in the first direction, the farthest distance of the third accommodating chamber 350 relative to the first mounting wall 220 is H 3 , H 3 Less than H 1 .

[0045] The above-mentioned technical solution of providing the third containing chamber 350 on the bracket 300 to increase the heat dissipation in the high-voltage control box in the containing chamber 210 has been described. 3 Less than H 1 , the third accommodating compartment 350 can also utilize the space of the electronic component 100 in a direction parallel to the first installation wall 220 to avoid increasing the overall volume of the high-voltage control box.

[0046] As a preferred alternative to the above solution, please refer to Figure 1 , Figure 3 , Figure 4 ,in Figure 4 yes Figure 1 Another schematic diagram of the positional relationship between the battery cluster management module 400 and the box body 200, Figure 4 The electronic component 100 is not shown; in some embodiments, H 3 Less than H 2 Through the above solution, the third storage compartment 350 can utilize the space of the housing 410 of the battery cluster management module 400 in a direction parallel to the first installation wall 220 to avoid the third storage compartment 350 affecting the installation position of the housing 410 .

[0047] For further information, please refer to Figure 1 , Figure 5 ,in Figure 5The figure is an overall schematic diagram of the high-voltage control box of some embodiments of the utility model from another perspective; in some embodiments, the first mounting wall 220 has an air inlet 250, and the accommodating chamber 210 is connected to the outside through the air inlet 250, and the air inlet 250 is used to allow outside air to enter the accommodating chamber 210. Through the above scheme, the heat of the electronic component 100 arranged on the first mounting wall 220 can be heat-exchanged with the outside through the air inlet 250, thereby enhancing the heat dissipation function of the high-voltage control box. Without departing from the inventive concept of the utility model, those skilled in the art can set more air inlets 250 on the first mounting wall 220.

[0048] For further information, please refer to Figure 5 The box body 200 also has an air outlet 260 connected to the accommodating chamber 210. The accommodating chamber 210 is connected to the outside through the air outlet 260. The air outlet 260 is used to allow the gas in the accommodating chamber 210 to pass through. Through the above scheme, air can enter the accommodating chamber 210 from the outside through the air inlet 250, and return to the outside through the air outlet 260 after absorbing the heat in the accommodating chamber 210, thereby promoting the heat dissipation of the high-voltage control box.

In the prior art, a cooling pipe for cooling the battery cluster is arranged on one side of the top wall 240 of the high-voltage control box in the energy storage system and around the top wall 240; since the top wall 240 and the side wall 230 are at an angle to each other, arranging the air outlet 260 in the above embodiment on the side wall 230 can prevent liquid from entering the accommodating chamber 210 from the air outlet 260 of the side wall 230. Furthermore, in some embodiments, the air inlet is arranged on the side of the first mounting wall 220 away from the air outlet 260. The above scheme enables the airflow in the accommodating chamber 210 to cover more electronic components 100, thereby enhancing the heat dissipation function.

In addition, the air pressure in the accommodating chamber 210 can also be reduced, so that the cold air from the outside can enter the accommodating chamber 210 through the air inlet 250, thereby promoting air circulation.

[0051] The embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the utility model.
