Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation of energy storage containers, in particular to a battery cooling device suitable for energy storage containers. Background Art

[0002] Containerized battery energy storage systems are widely used in the battery industry due to their large capacity, short construction period, high reliability, flexible installation and scheduling, and strong environmental adaptability. Due to their high integration, a large number of batteries are closely arranged in a limited space, and the large amount of heat generated is difficult to dissipate.

[0003] Most of the existing battery cooling devices of energy storage containers adopt simple air cooling. This heat dissipation structure is too simple. Therefore, some people think of setting an insulating cylinder that can store coolant outside the air duct to reduce the temperature of the wind. For example, the Chinese utility model patent with announcement number CN218513593U specifically discloses a high heat dissipation battery energy storage container.

[0004] However, during actual use of the battery cooling device of the energy storage container, people will find that the exhaust pipe of the device is not provided with a dust-proof structure, which causes the blower to easily suck in dust and other impurities in the external air and blow them into the container, affecting its normal use. Utility Model Content

[0005] The purpose of the utility model is to provide a battery cooling device suitable for an energy storage container to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a battery cooling device suitable for an energy storage container, comprising a container body and an outer box body, the outer box body is arranged at the end of the container body, an air inlet is arranged above the outer box body, a limit sleeve is arranged on the outer side of the air inlet, the limit sleeve and the air inlet are threadedly connected, a mounting groove is arranged above the air inlet, an annular grid is arranged in the mounting groove, a dustproof net is fixed on the annular grid, and a pressure ring for pressing the annular grid is fixed on the inner side of the limit sleeve; a cooling box is arranged inside the outer box body, a cooling air duct runs through the cooling box, a blower is arranged above the cooling box, the exhaust port of the blower is connected to the cooling air duct, the exhaust port of the blower is connected to the air inlet through a pipeline, and the end of the cooling air duct extends into the container body and is connected to an air distribution duct.

[0007] The dry air from the outside is drawn into the cooling air duct by the exhaust fan, and the impurities are filtered out by the dustproof net during the process. Coolant can be added to the cooling duct to reduce the temperature of the air in the cooling air duct. Finally, the air is blown out from the air distribution duct to cool the batteries inside the container body.

[0008] Preferably, a vent is provided at a position near the upper side of the container body, and a louver is provided in the vent. The vent is used to ensure air circulation inside the container body.

[0009] Preferably, the outer box body is fixed to the container body by bolts, thereby achieving detachable installation.

[0010] Preferably, the cooling box is provided with a water inlet and a water outlet, both of which penetrate the outer box body, and valves are provided on the water inlet and the water outlet.

[0011] Preferably, a plurality of blowing outlets are evenly arranged below the air distribution pipe, and the blowing outlets are arranged in a rectangular array.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model draws external air into the cooling air duct through a blower, reduces the temperature of the air through the coolant in the cooling box, and finally blows it out from the air distribution duct to cool the batteries in the container body. When the air passes through the air inlet, impurities therein will be blocked by the dustproof net to prevent external dust and impurities from entering. The provision of a limit sleeve to fix the dustproof net can also facilitate later disassembly and maintenance, thereby improving the practicality of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The blower draws dry air from the outside into the cooling air duct 10, and during the process, impurities are filtered out by the dustproof net 14. Coolant can be added to the cooling duct to reduce the temperature of the air in the cooling air duct 10, and finally the air is blown out from the air distribution duct 11 to cool the batteries inside the container body 1.
