In this embodiment, the driving fan 40 disposed in the air inlet 13 and/or the air outlet 14 drives the airflow in the battery compartment 10a to flow, so as to reduce the temperature difference at each position in the battery compartment 10a and accelerate the cooling of the battery.
Further, the air flow in the battery compartment 10a flows in from the outside of the housing 11 and flows into the equipment compartment 10b, thereby accelerating the flow of the gas in the equipment compartment 10b and also accelerating the flow of the gas in the equipment compartment 10b out of the housing 11. This can reduce the temperature difference at each position in the equipment compartment 10b and accelerate the heat dissipation of the equipment compartment 10 b.

Specifically, the partition wall 12 extends in the width direction of the housing 11, and the battery compartment 10a is formed between the partition wall 12, the end wall 11c, the first side plate 11a, and the second side plate 11 b. In this embodiment, the partition wall 12 extends in the width direction of the housing 11 and is parallel to the end wall 11c, so that the battery compartment 10a has a rectangular structure, facilitating the installation of the partition wall 12 and the battery cluster 20. Four sets of battery clusters 20 which are oppositely arranged are arranged in the battery compartment 10a, and each battery cluster 20 comprises two oppositely arranged battery racks, and a battery control box which are arranged on the battery racks.
Further, the air inlet 13 is disposed on the end wall 11 c. In this embodiment, the end plate 11c and the partition wall 12 are disposed opposite to each other along the length direction of the housing 11, so that the distance between the air inlet 13 and the air outlet 14 is increased to the maximum extent, and the time from when the air flows into the battery compartment 10a from the air inlet 13 to when the air flows out of the battery compartment 10a from the air outlet 14 is increased, thereby increasing the heat exchange time of the air in the battery compartment 10a, and improving the air cooling efficiency of the battery compartment 10 a.
Further, the housing 11 further includes a gas permeable box door 11d connecting the first side plate 11a and the second side plate 11b and disposed opposite to the end wall 11c, and the liquid cooling unit 30 has a liquid cooling outlet 32 exposed in the equipment compartment 10b, wherein the liquid cooling outlet 32 is opposite to the gas permeable box door 11 d.
In this embodiment, the ventilation box door 11d is configured as a split steel mesh door, which increases the heat exchange area of the equipment compartment 10b to the maximum extent, and facilitates the heat exchange between the equipment compartment 10b and the air outside the housing 11. The heat generated by the liquid cooling unit 30 is exhausted through the liquid cooling exhaust port 32 and is exhausted out of the housing 11 from the gas box door 11d, and because the gas box door 11d and the end wall 11c are oppositely arranged along the length direction of the housing 11, the distance between the gas box door 11d and the end wall 11c is increased to the greatest extent, so that the heat generated by the liquid cooling unit 30 is prevented from flowing to the end wall 11c, the heat generated by the liquid cooling unit 30 is prevented from entering the battery compartment 10a from the air inlet 13 on the end wall 11c, and the air cooling effect in the battery compartment 10a is further ensured.
Further, the box body 10 further includes a partition 15 connecting the partition wall 12 and the first side plate 11a and located in the equipment compartment 10b, wherein the partition 15 divides the equipment compartment 10b into a heat exchange chamber 10b1 and an electrical chamber 10b 2. In this embodiment, the partition 15 is provided to insulate the heat exchange chamber 10b1 and the electrical chamber 10b2, thereby reducing heat exchange between the heat exchange chamber 10b1 and the electrical chamber 10b 2. The partition 15 may have the same structure as the partition 12, such as a sandwich insulation board, or may have a structure different from that of the partition 12, so long as the installation strength is ensured and the heat insulation effect is achieved.
Specifically, the liquid cooling unit 30 is disposed in the heat exchange chamber 10b1, and the air outlet 14 is opened toward the heat exchange chamber 10b 1. In this embodiment, the setting of baffle 15 carries out certain sheltering from to the gas of air outlet 14 to produce the backward flow when avoiding the direct flow of air outlet 14 combustion gas to liquid cooling unit 30. When gas meets the liquid cooling unit 30 and generates backflow, the backflow can contain heat generated by the liquid cooling unit 30, so that the heat around the air outlet 14 is increased, the possibility that the generated heat flows back into the battery compartment 10a from the air outlet 14 is increased, and the scheme avoids the situation.
Further, the liquid cooling unit 30 and the air outlet 14 are located on two sides of a symmetrical plane of the first side plate 11a and the second side plate 11 b. In this embodiment, as shown in fig. 2, the liquid cooling unit 30 and the air outlet 14 are arranged along a diagonal line of the equipment compartment 10b, so that the distance between the air outlet 14 and the liquid cooling unit 30 is increased to the greatest extent, and the influence of the liquid cooling unit 30 on the air outlet 14 is reduced.
Of course, in some embodiments, the liquid cooling unit 30 may also be located on the same side of the symmetry plane of the first side plate 11a and the second side plate 11b as the air outlet 14, that is, the liquid cooling unit 30 and the electrical room 10b2 are arranged along the diagonal of the equipment compartment 10b, which enables better heat exchange of the liquid cooling unit 30 in the heat exchange room 10b 1.
Further, the energy storage container further includes an energy storage converter 50 disposed in the heat exchange chamber 10b1 and opposite to the liquid cooling unit 30 along the width direction of the housing 11. In this embodiment, the energy storage container can be configured as a user-side energy storage container after having the energy storage converter 50. In some embodiments, the energy storage container may also be configured without the energy storage ac 50, and thus configured as a grid-side energy storage tank. Energy storage AC ware 50 sets up along the width direction of shell 11 with liquid cooling unit 30 relatively, and energy storage AC ware 50 sets up along the length direction of shell with air outlet 14 relatively, and energy storage AC ware 50 sets up along the diagonal of equipment cabin 10b with electric room 10b2, can play the effect of sheltering from liquid cooling unit 30 and air outlet 14, avoids the heat that liquid cooling unit 30 produced to influence air outlet 14, still makes the spatial layout in the equipment cabin 10b more reasonable.
Further, the energy storage converter 50 has a variable flow air inlet 51 and a variable flow air outlet 52 exposed in the heat exchange chamber 10b1, the variable flow air inlet 51 is opposite to the gas permeable box door 11d, and the air outlet 14 is opposite to the end of the energy storage converter 50 having the variable flow air outlet 52. In this embodiment, the variable flow air inlet 51 and the variable flow air outlet 52 are disposed at two ends of the energy storage converter 50 along the length direction of the housing 11, and the variable flow air outlet 52 and the air outlet 14 are disposed opposite to each other along the length direction of the housing 11, so as to prevent air discharged from the air outlet 14 from entering the energy storage converter 50 and accelerate the discharge of heat in the energy storage converter 50.
Specifically, the energy storage converter 50 is spaced from the partition wall 12. In this embodiment, a certain gap is provided between the energy storage converter 50 and the partition wall 12, so that heat dissipation is facilitated, and meanwhile, the maintenance of the energy storage converter 50 or the air outlet 14 by an operator in the later period in the gap is facilitated.
Referring to fig. 3, in particular, the case body 10 further includes an air-permeable side door 16 disposed on the second side plate 11b to open or close the heat exchange chamber 10b 1. In this embodiment, the side vent door 16 is configured as a steel mesh door, so that heat exhausted from the variable flow exhaust port 52 and the air outlet 14 is rapidly exhausted from the heat exchange chamber 10b1 through the side vent door 16.
