Specifically, external air enters the energy storage container 1 through the air inlet 10, is cooled by the refrigeration device 20 and enters the air supply channel 30; the cooled cold air is input into the battery rack 2 through the air supply channel 30 and descends along the internal channel of the battery rack 2 to exchange heat with the battery rack 2; the air heat-exchanged with the battery frame 2 is discharged through the air outlet 40 after being heated.

The air cooled by the refrigerating device 20 has the advantages of reduced temperature and increased density, and has a downward flowing trend, and the air supply channel 30 is arranged above the battery frame 2, so that the cold air can naturally flow downwards in the battery frame 2, the flowing and heat absorption speed of the cold air in the battery frame 2 can be accelerated, and the heat dissipation rate is improved.

The energy storage container 1 developed by the utility model has the function of circulating heat dissipation, can improve the heat dissipation efficiency of the energy storage container 1, and can obviously reduce the working temperature of the energy storage container 1.

Referring to fig. 1, in some embodiments, the cross-sectional area of the air supply passage 30 near the end of the cooling device 20 is larger than the cross-sectional area near the end of the battery rack 2 in the air supply direction.

In the direction of air supply, the cross-sectional area of the air supply channel 30 gradually decreases, which is favorable for accelerating the cool air, and the cool air enters the battery rack 2 at a faster speed, thereby improving the cooling speed.

In some embodiments, the periphery of the air supply channel 30 is covered with insulation cotton, so as to weaken heat exchange between the cool air in the air supply channel 30 and the air in the internal cavity of the energy storage container 1 outside the air supply channel 30.

The air density near the lower part of the first side plate 1-1 is increased, the air temperature is lower, meanwhile, the air inlet 10 is arranged at the lower part of the rear end of the first side plate 1-1 and staggered with the air outlet 40 at the upper part of the front end of the second side plate 1-2, so that the high-temperature air discharged by the air outlet 40 can be prevented from being directly sucked into the interior, the energy consumption of the refrigerating device 20 can be increased when the high-temperature air enters the refrigerating device 20, and the heat dissipation in the battery frame 2 is also unfavorable.

According to the utility model, the air with lower temperature outside can be quickly sucked into the energy storage container 1, and the air with lower temperature enters the refrigerating device 20, so that the energy consumption of the refrigerating device 20 can be reduced, and the heat dissipation in the battery frame 2 is also directly facilitated.
