[0008] Beneficial effect: By setting an air duct structure between two adjacent battery cells, a first flow opening is provided at one end of the air duct structure facing the air circulation channel, and a second flow opening is provided at one end of the air duct structure away from the air circulation channel, and the first flow opening is connected to the second flow opening. When the airflow power device is working, the cold air is driven to flow through the air circulation channel and the air duct structure in sequence, or to flow through the air duct structure and the air circulation channel in sequence. Since the air duct structure is set between two adjacent battery cells, when the cold air passes through the air duct structure, the battery cells on both sides of the air duct structure can be cooled. At the same time, when the cold air flows through the air circulation channel, the battery cells on both sides of the air circulation channel can also be cooled. Therefore, the air-cooled plug-in box can dissipate heat in time, and has good heat dissipation performance.

[0009] In an optional embodiment, the air-cooled plug-in box further includes an air-blocking structure, which closes the top of the air circulation channel and an end directly opposite to the mounting plate.

[0010] Beneficial effect: By setting up a wind-blocking structure, the wind-blocking structure closes the top of the air circulation channel and the end opposite to the mounting plate, and then cooperates with the bottom panel, the front end of the air circulation channel is connected to the airflow power device, the top, bottom and rear of the air circulation channel are all closed, and the two sides of the air circulation channel are connected to the air duct structure between the battery cells, so that only air is allowed to enter and exit from between the battery cells, thereby improving the heat dissipation efficiency of the battery module, effectively preventing air backflow, and making the air-cooled plug-in box dissipate heat better.

[0018] Beneficial effect: The airflow power device is an exhaust device. When the exhaust device is working, the cold air enters the air duct structure from the second flow port, flows through the air duct structure and then enters the air circulation channel through the first flow port, and then flows to the outside of the air-cooled plug-in box after passing through the exhaust device. Since the air duct structure is arranged between two adjacent battery cells, when the cold air passes through the air duct structure, the battery cells on both sides of the air duct structure can be cooled.

Air-cooled plug-in boxes generate a lot of heat energy during the charging and discharging process. If the heat is not dissipated in time or the heat is uneven, it will not only affect the service life of the battery, but also cause thermal safety hazards.

[0046] Combine the following Figures 1 to 8 , describing an embodiment of the utility model.

The duct structure 14 is provided with a first flow port at one end facing the air circulation channel, and a second flow port 14-1 is provided at one end of the duct structure 14 away from the air circulation channel, and the first flow port is connected to the second flow port 14-1; the airflow power device is arranged on the mounting plate 1 and is directly opposite to the air circulation channel.

[0049] In this embodiment, by setting an air duct structure 14 between two adjacent battery cells 13, a first flow port is provided at one end of the air duct structure 14 facing the air circulation channel, and a second flow port 14-1 is provided at one end of the air duct structure 14 away from the air circulation channel, and the first flow port is connected with the second flow port 14-1. When the airflow power device is working, the cold air is driven to flow through the air circulation channel and the air duct structure 14 in sequence, or to flow through the air duct structure 14 and the air circulation channel in sequence. Since the air duct structure 14 is set between two adjacent battery cells 13, when the cold air passes through the air duct structure 14, the battery cells 13 on both sides of the air duct structure 14 can be cooled. At the same time, when the cold air flows through the air circulation channel, the battery cells 13 on both sides of the air circulation channel can also be cooled. Therefore, the air-cooled plug-in box can dissipate heat in time, and the heat dissipation performance is good.

Both sides of the air circulation channel are connected to the air duct structure 14 between the battery cells 13, so that only air is allowed to enter and exit from between the battery cells 13, thereby improving the heat dissipation efficiency of the battery module 5, effectively preventing air backflow, and enabling the air-cooled plug-in box to dissipate heat better.

When the air flow dynamic device is working, it can generate cold air in the air circulation channel to pass through the vent 21-3, flow through the air flow dynamic device, and then flow to the outside of the air-cooled plug-in box. The air flow dynamic device is embedded in the induced draft component 21, which can reduce the length of the entire air-cooled plug-in box.
