[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0022] See also Figure 1-3As shown, the utility model provides a cooling device for an energy storage power station, including a cabinet 1, wherein the cabinet 1 is divided into a battery storage compartment located at the upper part and an equipment compartment located at the lower part, wherein six energy storage batteries are arranged in sequence from the upper part to the lower part in the battery storage compartment, and a serpentine cooling pipe 3 is arranged on the upper surface of each energy storage battery, wherein one end of the serpentine cooling pipe 3 is connected to a vertically arranged water supply pipe 31 through a water inlet pipe B32, and the other end is connected to a vertically arranged water return pipe 35 through a water outlet pipe B33; and the top of the water supply pipe 31 is connected to a storage The bottom of the water tank 200 and the bottom of the return pipe 35 are connected to the top of a return tank 100. The return tank 100 is provided with a water pump for conveying the coolant in the return tank 100 to the water storage tank 200. Based on the above, when in use, the coolant is conveyed to the serpentine cooling pipe 3 by the water storage tank 200, and then the corresponding energy storage battery is cooled by heat exchange. The heated coolant after cooling is conveyed to the heat exchange system 400, and the heat exchange system 400 is used to air-cool the coolant passing through the heat exchange system 400.

[0023] On the basis of the above, if Figure 5 In order to ensure that the cooling pipe system 300 composed of the serpentine cooling pipe 3, the water inlet pipe B32, the return pipe 35, the water supply pipe 31 and the water outlet pipe B33 can achieve the same cooling effect on each energy storage battery, that is, it is required to keep the coolant flow rate in each serpentine cooling pipe 3 the same in practice, that is, a valve 34 is provided on any water outlet pipe B33. By using the setting of the valve 34, when the liquid level in the water storage tank 200 is within a small fluctuation range during use, the opening of the valve 34 is adjusted, thereby achieving the control of the coolant flow rate in the serpentine cooling pipes 3 to be the same.

[0024] Of course, in a possible implementation, the valve 34 is a flow control valve. When the liquid level in the water tank 200 fluctuates during use, a controller connected to the flow control valve controls the flow control valve to open and close and adjust the opening degree, thereby adjusting the flow rate of the coolant.

[0025] Specifically, in the present application, the water tank 200 is arranged at the top position of the battery storage compartment, and uses its own gravity to transport the coolant, and the return water tank 100 is arranged at the bottom of the equipment compartment.

Then, when in use, the gas in the equipment compartment is extracted by the cooling fan, and the ambient air enters the equipment compartment through the air inlet 12. The air entering the equipment compartment will pass through the heat exchange system 400, and then heat is exchanged with the heat exchange system 400 to cool the coolant.

[0027] Specifically, Figure 4 The heat exchange system 400 provided includes a water storage box A40, a water storage box B42, and a plurality of heat exchange tubes 41 connected between the water storage box A40 and the water storage box B42; a water inlet pipe A401 connected to the cooling pipe system 300 is arranged at the top of the water storage box A40, and a water outlet pipe A421 connected to the return water tank 100 is arranged at the bottom of the water storage box B42, and the heat exchange tube 41 is a metal tube. The arrangement of the metal tube facilitates heat exchange between the coolant and the ambient air, thereby completing heat dissipation.

[0028] In a possible implementation, the metal tube is a copper tube, and the wall thickness of the copper tube is 0.075 cm, the inner diameter of the metal tube is 0.25 cm, and the gap between two adjacent metal tubes is 0.3 cm.
