Description

Technical Field

[0001] The utility model relates to the technical field of battery energy storage, and in particular to a high-efficiency air-cooled energy storage system. Background Art

[0002] Energy storage batteries generate heat when working. If the heat cannot be dissipated in time, the battery temperature will rise and even cause accidents. Therefore, the heat dissipation of energy storage batteries is very important and has great significance for ensuring the safe and efficient operation of energy storage systems.

[0003] Currently, in air-cooled energy storage systems, battery heat dissipation is mainly achieved by the air conditioning refrigeration system. The air duct is shared by the entire energy storage system. The battery rack in the middle is far away from the air conditioner, and the cooling effect will be much worse, resulting in temperature differences between each battery PACK, which will eventually affect the working efficiency of the entire energy storage system. Utility Model Content

Each battery cluster rack is equipped with an independent air conditioner and air cooling module. The air conditioner is installed on the corresponding box door, which can improve the heat dissipation performance on the basis of high-density integration with maximized battery energy.

[0006] A high-efficiency air-cooled energy storage system is provided with a plurality of battery cluster racks in an energy storage box. The battery cluster racks are provided with multiple layers of air-cooled battery PACKs, and multiple air-cooled battery PACKs are arranged on each layer. Each battery cluster rack is equipped with an independent air-cooling module. The air-cooling module comprises a connecting air duct, a top air duct, a rear air duct and a guide plate. The top air duct is placed on the top of the battery cluster rack. The front side of the top air duct is connected to the connecting air duct, and the rear side is connected to the vertically arranged rear air duct. The connecting air duct is sealed and connected to the top air outlet of the air conditioner. The rear air duct is provided with a plurality of guide plates in the vertical direction, and the guide plates guide cooling air into each layer of air-cooled battery PACKs.

[0007] Preferably, L-shaped extension edges are provided on the left and right sides of the rear air duct, and the L-shaped extension edges are fixed to the rear side of the battery cluster frame by bolts.

[0008] Preferably, baffles are provided on the left and right sides of the battery cluster frame.

[0011] The beneficial effects of the utility model are:

[0012] Each battery cluster rack is equipped with independent air conditioning and air cooling modules. The air conditioner is installed on the corresponding box door. The air duct is short and the loss of cold air during the duct transportation is small. It can improve the heat dissipation performance on the basis of high-density integration to maximize battery energy. The cooling effect of each battery rack is similar, and the temperature difference between each air-cooled battery PACK is small, so the working efficiency of the entire energy storage system is high.

[0018] See also Figure 1-4 The utility model relates to a high-efficiency air-cooled energy storage system. A plurality of battery cluster racks 1 are arranged in an energy storage box. The battery cluster rack 1 is provided with multiple layers of air-cooled battery PACK4. Each layer is provided with multiple air-cooled battery PACK4. Each battery cluster rack 1 is provided with an independent air-cooling module 2. The air-cooling module 2 includes a connecting air duct 2.1, a top air duct 2.2, a rear air duct 2.3 and a guide plate 2.4. The top air duct 2.2 is placed on the top of the battery cluster rack 1. The front side of the top air duct 2.2 is connected to the connecting air duct 2.1. The connecting air duct 2.1 is connected to the vertically arranged rear air duct 2.3 at the rear side. The connecting air duct 2.1 is sealed and connected to the top air outlet of the air conditioner 3. The air conditioner 3 is installed on the door 5 of the energy storage box. The rear air duct 2.3 is provided with a plurality of guide plates 2.4 in the vertical direction. The guide plates 2.4 guide the cooling air into each layer of the air-cooled battery PACK4. The air-cooled battery PACK4 adopts the rear side air intake and the front side air outlet, so that the air inlet and outlet of the air-cooled battery PACK4 will not be blocked by the battery cluster frame. The rear air duct 2.3 is provided with L-shaped extension edges 2.3.1 on the left and right sides. The L-shaped extension edges 2.3.1 are fixed to the rear side of the battery cluster frame 1 by bolts. The battery cluster frame 1 is provided with baffles 2.5 on the left and right sides to prevent the cooling air from not passing through the inside of the air-cooled battery PACK4 and directly discharging forward from the side of the battery cluster frame 1.

[0019] The air conditioner 3 can be opened or closed along with the box door. When the box door 5 is closed, the top air outlet of the air conditioner 3 is connected to the connecting air duct 2.1, and the cooling air enters the rear air duct 2.3 from the connecting air duct 2.1 through the top air duct 2.2, and then is guided into the interior of each air-cooled battery PACK4 through the guide plate 2.4 to cool the interior of the air-cooled battery PACK4. The cooled hot air is discharged from the battery compartment from the return air outlet at the bottom of the air conditioner 3.

[0020] The battery cluster frame 1 and the air cooling module 2 are assembled and installed in the battery compartment, which is convenient for disassembly and maintenance.

[0021] Each battery cluster rack is equipped with independent air conditioning and air cooling modules. The air conditioner is installed on the corresponding box door. The air duct is short and the loss of cold air during the duct transportation is small. It can improve the heat dissipation performance on the basis of high-density integration to maximize battery energy. The cooling effect of each battery rack is similar, and the temperature difference between each air-cooled battery PACK is small, so the working efficiency of the entire energy storage system is high. The air cooling module is directly installed on the battery cluster rack, which is simple and labor-saving to install.

[0022] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
