[0001] The utility model relates to the technical field of energy storage cabinets, in particular to an air-cooled energy storage cabinet. Background Art

[0002] Energy storage battery cabinets, devices that integrate energy storage devices and power management systems, play a crucial role in modern energy management and power systems. Air-cooled energy storage battery cabinets, among other things, utilize air-cooling technology to store and manage electrical energy to meet energy needs in various scenarios. With the rapid development of renewable energy and the expanding electric vehicle market, demand for energy storage batteries is also increasing. Air-cooling technology, due to its low cost and ease of maintenance, holds considerable promise for energy storage battery cooling.

[0003] Existing air-cooled energy storage battery cabinets mostly use split air conditioners (one internal unit inside the cabinet and one external unit), or wall-mounted air conditioners at the cabinet front door, blowing cool air directly onto the battery cabinet packs. However, this cooling method causes the temperature of several battery packs near the air conditioner's cold air outlet to be relatively low, while the temperature of several battery packs farther away is relatively high, resulting in uneven cooling of the battery packs. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technical solutions, the utility model provides an air-cooled energy storage cabinet, which can effectively solve the technical problem of uneven cooling effect of each battery PACK package inside the energy storage cabinet.

[0007] Furthermore, a channel partition is installed on the top of the battery installation area to isolate it from the cold air area, so that the cold air in the hot air area flows along the top of the battery installation area into the cold air area.

[0008] Furthermore, one end of the cold air zone and the hot air zone is provided with a conductive air guide port, and the opening of the air guide port gradually decreases toward the end of the cold air zone.

[0009] Furthermore, the box body is equipped with a first door fan which leads to the hot air zone when opened, and the wall-mounted air conditioner is installed on a side of the first door fan close to the hot air zone.

[0010] Furthermore, the box body is equipped with a second door leaf which leads to the cold air zone after being opened.

[0011] Furthermore, a power distribution area is provided in the box, and the power distribution area is provided below the cold air area, the hot air area and the battery installation area. A power distribution unit for power distribution is installed in the power distribution area, and the box is provided with a third door leaf which leads to the power distribution area when opened.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The utility model adds a cold air zone, a hot air zone and a battery PACK package that are connected from end to end in the box.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1-5 As shown, the present invention provides an air-cooled energy storage cabinet. When the energy storage cabinet is in operation, cold air is passed into the interior. By optimizing the internal structure of the energy storage cabinet, the temperature of each battery pack in the energy storage cabinet is reduced to a balanced state, avoiding temperature differences among the battery packs. The specific structure of the energy storage cabinet mainly includes a box body 1, which is provided with a cold air zone 2, a hot air zone 3 and a battery installation zone 4. The battery installation zone 4 is used to install multiple battery packs 6 for power supply. The battery installation zone 4 is arranged between the cold air zone 2 and the hot air zone 3 in the box body 1. As the two ends of the battery pack 6 are connected to the cold air zone 2 and the hot air zone 3 respectively, a convenient flow of cold air and hot air is formed to cool the battery pack 6.

[0023] In the hot air zone 3, a wall-mounted air conditioner 5 for providing cold air is installed. The top of the cold air zone 2 passes through the battery installation area 4 and is connected to the hot air zone 3, so that the cold air in the hot air zone 3 flows to the cold air zone 2. A plurality of battery PACK packages 6 for power supply are installed in the battery installation area 4. One end of the battery PACK package 6 is connected to the cold air zone 2, and the other end of the battery PACK package 6 is connected to the hot air zone 3. A circulating gas structure is formed inside. As the cold air enters the battery PACK package 6 from the cold air zone 2, the hot air in the battery PACK package 6 is replaced and discharged into the hot air zone 3 to be neutralized, thereby achieving the effect of cooling the battery PACK package 6.

[0024] When the cold air flows from the hot air zone 3 to the cold air zone 2, an air guide port 9 for the flow of cold air is set at the position where the cold air zone 2 and the hot air zone 3 are connected, and the opening size of the air guide port 9 gradually decreases toward one end of the cold air zone 2 to prevent backflow when the cold air flows.

[0025] To ensure uniform cooling of all battery packs 6 within battery installation area 4, each battery pack 6 is equipped with a fan 7, which is installed inside the battery pack 6 near one end of the cold air zone 2. When activated, the cool air within the cold air zone 2 is blown into the battery pack 6 by the fan 7. The cool air naturally sinks throughout the cold air zone 2 and is exposed to all battery packs 6, eliminating temperature differences.

[0026] In addition, a channel partition 8 is installed on the top of the battery installation area 4 to isolate it from the cold air area 2, so that the cold air in the hot air area 3 flows along the top of the battery installation area 4 into the cold air area 2. On the one hand, it can maintain the sealing between the battery installation area 4. On the other hand, the top conductive structure allows the cold air to enter the cold air area 2 and then, through the principle of natural sinking, the cold air is distributed throughout the cold air area 2, ensuring contact with all battery PACK packages 6, thereby avoiding temperature differences.

[0027] At one end of the box body 1, a first door 10 is installed, which leads directly to the hot air zone 3 when opened, and the wall-mounted air conditioner 5 is installed on the side of the first door 10 close to the hot air zone 3, while the other side of the first door 10 is installed with the outdoor unit corresponding to the wall-mounted air conditioner 5. At this time, the wall-mounted air conditioner 5 will move outward synchronously with the opening of the first door 10, which not only saves space in the hot air zone 3, but also makes it convenient to open the first door 10 to maintain the wall-mounted air conditioner 5.

[0028] At the other end of the box body 1, a second door leaf 11 is installed, which leads directly to the cold air zone 2 after being opened. At this time, the battery PACK package 6 installed in the battery installation area 4 is installed from one end of the cold air zone 2. After the battery PACK package 6 is installed in the battery installation area 4, the second door leaf 11 can be closed.

[0029] A power distribution area 12 is also provided in the box body 1. The power distribution area 12 is located below the cold air area 2, the hot air area 3 and the battery installation area 4, and a power distribution unit 13 for power distribution processing is installed inside. A third door leaf 14 is also installed on the box body 1, which leads directly to the power distribution area 12 after opening. By opening the third door leaf 14, the power distribution unit 13 in the power distribution area 12 can be installed and maintained.

[0030] Compared with traditional technology, this technical solution adds a cold air zone 2, a hot air zone 3 and a battery PACK package 6 that are connected at the end to the end in the box 1. By adding a wall-mounted air conditioner 5 that provides cold air in the hot air zone 2, a sealed cold air circulation channel is formed inside, and the hot air discharged from the battery PACK package 6 can be neutralized. At the same time, the cold air in the cold air zone 2 can be sucked into all the battery PACK packages 6 after natural sinking, so that all the battery PACK packages 6 do not have the problem of temperature difference when cooling, and the cooling effect is better.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description. It is intended that all variations within the meaning and range of equivalents of the claims be encompassed within the present invention, and any reference numerals in the claims should not be construed as limiting the claims to which they relate.
