[0057] Now, exemplary embodiments according to the present invention will be described in more detail with reference to the accompanying drawings.

[0058] The utility model provides an energy storage container, in which batteries or high-power electrical equipment are usually placed, and the heat dissipation requirement is high. A battery rack is arranged in the box of the energy storage container, and the battery rack is used to place the electrical equipment, wherein the battery rack can be a detachable multi-layer frame structure, or can be a flat plate or a single-layer frame and other forms, and is used to place electrical equipment including batteries.

[0059] like Figure 1 As shown, the energy storage container 100 includes a liquid storage tank 20, in which the coolant flows, and the liquid storage tank 20 is located at the bottom of the energy storage container 100. The liquid storage tank 20 can be surrounded by a floor, a bottom side beam and a bottom cross beam, or it can be formed by arranging baffles on four peripheries, which is not limited here. The liquid storage tank 20 includes a bracket 21, a liquid inlet 22 and a liquid outlet 23. The bracket 21 is used to support the battery rack 30 so that the battery rack 30 is isolated from the coolant in the liquid storage tank to prevent the electrical equipment from being immersed in the coolant and damaged. The bracket 21 is arranged along the first direction D1, and divides the liquid storage tank 20 into at least two sub-slots. One end of the bracket 21 has a notch U to connect adjacent sub-slots. The liquid inlet 22 is used to feed liquid into the liquid storage tank 20, and the liquid discharge port 23 is used to discharge liquid from the liquid storage tank 20, so that the coolant in the liquid storage tank 20 circulates to cool the box, or the liquid inlet 22 inputs coolant into the liquid storage tank 20, and discharges it from the liquid discharge port 23 after being stored for a certain period of time. The liquid inlet 22 and the liquid discharge port 23 are located at the same end of the liquid storage tank 20 along the first direction D1 or at both ends respectively. It should be noted that the liquid inlet 22 and the liquid discharge port 23 can be set to one or more as needed. The first direction D1 is not limited to the length direction of the box body of the energy storage container 100.

[0060] The energy storage container 100 cools the container by circulating the coolant in the liquid storage tank 20, which requires lower energy consumption than the commonly used refrigerator. At the same time, the coolant has a longer path in the liquid storage tank 20, so that the coolant can fully absorb the heat in the container, reduce the circulation frequency of the coolant, and further reduce the energy consumption required for cooling.

[0061] In a specific embodiment, Figure 1 , Figure 3 and Figure 4 As shown, the battery racks 30 are respectively arranged on both sides of the box along the second direction D2, and a grid 60 is arranged in the middle for people to pass through. Two brackets 21 along the length direction of the box divide the liquid storage tank 20 into three sub-slots along the second direction D2: the first sub-slot 20a, the second sub-slot 20b, and the third sub-slot 20c. The second direction D2 is perpendicular to the first direction D1. The first sub-slot 20a and the third sub-slot 20c are respectively provided with a liquid inlet 22, and the second sub-slot 20b is provided with a liquid discharge port 23. The notch U is arranged at one end of the bracket 21 away from the liquid inlet 22 or the liquid discharge port 23. Therefore, the flow direction of the coolant in the liquid storage tank 20 is to enter the first sub-slot 20a and the third sub-slot 20c from the two liquid inlets 22 respectively, flow to the other end, and then enter the second sub-slot 20b from the notch U, flow back in the opposite direction, and flow out after reaching the liquid discharge port 23.

[0062] Preferably, the notch U is located at the lower part of the bracket, that is, the upper surface of the bracket 21 is complete and the lower part thereof is open to avoid affecting the supporting effect of the bracket 21 on the battery rack 30 .

[0063] Preferably, the liquid inlet 22 is disposed at one end of the sub-slot below the battery rack 30, for example Figure 1 In the embodiment, the battery rack 30 is located on both sides of the box along the width direction of the box body, and the first sub-slot 20a and the third sub-slot 20c are located below the battery rack 30, so the liquid inlet 22 is set at one end of the first sub-slot 20a and the third sub-slot 20c. As a result, when the temperature is low, the coolant passes under the battery rack 30 where more heat is accumulated, so that the coolant has a better heat absorption and cooling effect.

[0064] Continue to refer Figure 1 The energy storage container 100 also includes a cooling circulation device 10, which is used to cool the coolant. The liquid inlet 22 is connected to the liquid outlet pipe 11 of the cooling circulation device 10, and the liquid outlet 23 is connected to the liquid inlet pipe 12 of the cooling circulation device.

[0065] Specifically, the cooling circulation device 10 includes an upper liquid tank 16 and a lower liquid tank 17, which are separated by a partition plate 18. The coolant is cooled once in the lower liquid tank 17, and the coolant enters the upper liquid tank 16 from the lower liquid tank 17 under the drive of the circulation pump 19 for secondary cooling. The upper liquid tank 16 has an inlet 13, and the lower liquid tank 17 has an outlet 14. The inlet 13 is used to connect to the liquid inlet pipe 12, and the outlet 14 is used to connect to the liquid outlet pipe 11. That is, the coolant flows out of the upper liquid tank 16 of the cooling circulation device 10 from the outlet 14, enters the liquid storage tank 20 from the liquid inlet 22 through the liquid outlet pipe 11, flows out from the liquid discharge port 23 of the liquid storage tank 20, and enters the lower liquid tank 17 from the inlet 13 through the liquid inlet pipe 12.

[0066] Preferably, the inlet 13 is lower than the drain port 23, so that the coolant naturally flows out from the liquid storage tank 20 to the cooling cycle device 10 under the action of gravity. Preferably, the outlet 14 is higher than the liquid inlet 22, so that the coolant naturally flows into the liquid storage tank 20 from the cooling cycle device 10 under the action of gravity. Therefore, the cooling energy consumption of the energy storage container 100 can be further reduced. Therefore, in order to control the discharge flow rate of the coolant, a regulating valve 15 is provided between the inlet 13 and the drain port 23, for example, it is provided on the liquid inlet pipe 12. In order to control the inlet flow rate of the coolant, a regulating valve 15 is provided between the outlet 14 and the liquid inlet 22, for example, it is provided on the liquid outlet pipe 11.

[0067] Preferably, if Figure 2 and Figure 5As shown, the energy storage container 100 also includes an exhaust port 40 and an air inlet 50. The exhaust port 40 is located at the top of the energy storage container 100 and is used to connect the exhaust equipment. The top can have a larger opening than other positions, so that more exhaust equipment can be installed. At the same time, since hot air gathers at the top, the exhaust port 40 is arranged at the top for easier heat dissipation. The air inlet 50 is located on the side panel of at least one side of the energy storage container 100, and the air inlet is set as a shutter, for example. The energy storage container 100 uses natural wind cooling to reduce energy consumption.

[0068] Further preferably, the air inlet 50 is located at the lower part of the side plate near the liquid storage tank 20. Therefore, the air entering through the air inlet 50 can accelerate the evaporation of the coolant (such as water) and enhance the cooling effect.

[0069] More preferably, the top of the energy storage container 100 is set to be higher in the middle than on both sides, close to an arch shape, and the exhaust port is located in the middle of the top of the energy storage container 100. Therefore, water accumulation on the top of the container can be prevented, and space is left for the installation of the exhaust equipment, so that the hot air emitted from the container can be gathered in the middle of the top, which is convenient for the exhaust equipment to quickly and centrally discharge the hot air.

[0070] The energy storage container 100 cools the box by circulating the coolant in the liquid storage tank 20, which requires lower energy consumption than the commonly used refrigerator. At the same time, the coolant flows through a longer path in the liquid storage tank 20, so that the coolant can fully absorb the heat in the box, reducing the circulation frequency of the coolant, thereby further reducing the energy consumption required for cooling. In addition, combined with the natural wind cooling method, the energy storage container 100 can achieve a better cooling effect while lowering energy consumption.

The terms used herein are only for describing specific implementation purposes and are not intended to limit the present invention. The features described herein in one embodiment may be applied to another embodiment alone or in combination with other features, unless the feature is not applicable or otherwise specified in the other embodiment.

According to the teachings of the present invention, more variations and modifications can be made, and these variations and modifications all fall within the scope of protection required by the present invention.
