Description

Technical Field

[0001] The utility model relates to the field of battery storage equipment, in particular to a box structure for placing energy storage batteries. Background Art

[0002] In today's society, people use electricity every day. With the rapid development of science, people's use of electricity has become more and more mature. Now they have mastered the technology of storing electricity. The battery cabinet is a device used to store batteries and use them.

[0003] Most of the existing battery cabinets have a cooling fan in the cabinet, which blows cold air toward the batteries placed in the cabinet, thereby dissipating heat for the running batteries; and in order to achieve dust and splash-proof effects, the existing battery cabinets usually use a closed cabinet to store the batteries.

[0004] However, the cold air blown out by the cooling fan in the above structure will collide and mix with the returning hot air, so that the cold air cannot circulate orderly and blow toward the battery, but forms turbulence, which affects the heat dissipation effect of the battery cabinet. Utility Model Content

[0005] The utility model aims to provide a box structure for placing energy storage batteries, in which air is blown toward the batteries through circulation in a first air duct and a second air duct.

[0008] As a preferred solution, there are multiple storage cavities on the storage rack, and the multiple storage cavities are arranged vertically, there are multiple first air outlets on the first air duct, and there are multiple second air outlets on the second air duct.

[0009] As a preferred solution, there are two racks, which are respectively located on both sides of the first air duct, there are two second air ducts, which are located on the side of the rack away from the first air duct, and the two second air ducts are respectively close to the two ends of the third air duct, and the refrigeration mechanism has two evaporators.

[0012] The beneficial effects of a box structure for placing energy storage batteries disclosed in the utility model are:

[0013] The air in the third air duct is sucked into the first air duct through the air supply device. During the inhalation process, when the air passes through the evaporator, the cold air emitted by the evaporator converts the air into cold air. The cold air is pushed by the air supply device to blow from the first air port to the storage cavity to cool the battery. The cold air exchanges heat with the battery and becomes hot air. The hot air enters the second pipe from the second air port under the push of the cold air continuously blown out from the first air port. The hot air in the second pipe flows to the third pipe, forming an air circulation effect, solving the problem of turbulence formed on the outside of the battery. The hot air in the second pipe passes through the evaporator when flowing to the third pipe. The evaporator reduces the temperature of the hot air to turn it into cold air, solving the problem that the hot air cannot be cooled quickly, resulting in the air blown to the battery being hot air, further improving the battery cooling efficiency.

[0024] A first air duct 122 is provided in the second chamber 12, and an air supply device 1222 is provided in the first air duct 122. In this embodiment, the air supply device 1222 is preferably a fan; two storage racks 121 are respectively located on both sides of the first air duct 122, and the storage racks 121 are connected to the first air duct 122; a first air outlet 1221 is opened on the first air duct 122.

[0026] Please refer to Figure 3 (The arrows indicate the direction of air flow).

[0027] The second chamber 12 is provided with a third air duct 124, which is located on the storage rack 121; one end of the first air duct 122 is connected and communicated with the middle of the third air duct 124, so that the air in the third air duct 124 is sucked into the first air duct 122 through the air supply device 1222 in the first air duct 122.

Driven by the cold air, the hot air enters the second air duct 123 from the second air outlet 1231 to complete the circulation of the air.

[0028] The utility model provides a box structure for placing energy storage batteries. The air in the third air duct is sucked into the first air duct through an air supply device. During the inhalation process, when the air passes through the evaporator, the cold air emitted by the evaporator converts the air into cold air. The cold air is pushed by the air supply device to blow from the first air port to the storage cavity to cool the battery. The cold air is converted into hot air after heat exchange with the battery. The hot air enters the second pipe from the second air port under the push of the cold air continuously blown out from the first air port. The hot air in the second pipe flows to the third pipe, forming an air circulation effect, solving the problem that the air will form turbulence on the outside of the battery. The hot air in the second pipe will pass through the evaporator when flowing to the third pipe. The evaporator reduces the temperature of the hot air to convert it into cold air, solving the problem that the hot air cannot be cooled quickly, resulting in the air blown to the battery being hot air, and further improving the battery cooling efficiency.
