[0002] The energy storage device usually consists of a cluster frame and a plurality of energy storage batteries, and the energy storage batteries are installed on the cluster frame. In the prior art, a plurality of energy storage batteries are usually installed on the cluster frame in a stacked manner. Since the energy storage batteries themselves generate some heat, if this heat cannot be effectively dissipated, it will cause individual energy storage batteries to short-circuit under high temperature conditions, thereby increasing the possibility of explosion. Since adjacent energy storage batteries are attached together, the heat generated by individual energy storage batteries is transferred to other energy storage batteries, which can easily form a chain effect and cause other energy storage batteries to short-circuit. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a device that can not only discharge all the heat generated by the energy storage battery to prevent the energy storage battery from exploding due to high temperature, but also reserve gaps between adjacent energy storage batteries to effectively prevent short circuits in other energy storage batteries caused by heat transfer.

[0005] Furthermore, an installation cavity is provided between the top of the cluster rack and the inner wall of the cabinet, and a cooling mechanism is provided in the installation cavity. The cooling mechanism includes a heat exchanger, an infusion pump and a condenser.

[0006] Furthermore, a sealing door is provided on one side of the cabinet, and a sealing plate adapted to the opening end of the accommodating cavity is fixedly connected to the inner wall of the sealing door.

[0007] Furthermore, an explosion-proof valve is provided on the energy storage battery and located on one side of the exhaust cavity, and the explosion-proof valve is connected to the exhaust cavity through a ventilation pipe.

[0008] Furthermore, a heat-insulating cotton pressing plate is provided on the top of the top plate.

[0009] Compared with the prior art, the beneficial effects produced by the utility model are: the utility model has a novel structure, ingenious conception, simple and convenient operation, and has the following advantages compared with the prior art: the utility model enables each energy storage battery to correspond to a heat dissipation channel, and each heat dissipation channel does not interfere with each other, which can effectively discharge the heat generated by the energy storage battery out of the cabinet body, avoiding explosion caused by high temperature, and at the same time, two adjacent energy storage batteries are separated by the heat dissipation cavity, which can effectively solve the problem of heat transfer between adjacent energy storage batteries in the prior art.

DETAILED DESCRIPTION

[0014] The following are specific embodiments of the present invention, and the technical solution of the present invention is further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0015] like Figure 1-3As shown, the utility model provides an explosion-proof cabinet-type energy storage device, including a cabinet body 1, a partition 2 is arranged in the middle of the cabinet body 1, cluster frames 3 are arranged on both sides of the partition 2, a closed cooling chamber 4 is arranged between the cluster frame 3 and the partition 2, a louver air outlet 5 connected with the cooling chamber 4 is opened on the rear side of the cabinet body 1, a closed exhaust chamber 6 is arranged between one side of the cluster frame 3 and the inner wall of the cabinet body 1, a plurality of groups of top plates 7 and support plates 8 are alternately arranged from top to bottom in the cluster frame 3, a storage battery accommodating chamber 9 is provided between the support plate 8 and the top plate 7 above the support plate 8, a closed heat dissipation chamber 10 is provided between the support plate 8 and the top plate 7 below the support plate 8, a plurality of heat dissipation holes 11 are provided on the support plate 8, an air inlet 12 is provided on one side of the accommodating chamber 9, a vent 13 is provided on the side of the heat dissipation chamber 10 away from the air inlet 12, and exhaust fans 14 are arranged above both sides of the cabinet body 1.

[0016] like Figure 1-3 As shown, the energy storage batteries on both sides of the cabinet 1 are separated by the partition 2, so that the energy storage batteries on both sides of the partition 2 do not affect each other; the energy storage batteries are placed in the accommodating cavity 9, and the heat generated by the energy storage batteries when storing or discharging energy is discharged into the heat dissipation cavity 10 through the heat dissipation holes 11. The wind outside the cabinet 1 passes through the louver air vents 5, the air inlet 12, the heat dissipation holes 11, and the vents 13 in sequence and enters the exhaust cavity 6 to form a plurality of heat dissipation channels. The cold wind passes through the energy storage batteries, takes away the heat on the energy storage batteries, and enters the exhaust cavity 6. Finally, the exhaust fan 14 takes the heat generated by the energy storage batteries out of the cabinet 1 to achieve cooling of the energy storage batteries. Each energy storage battery corresponds to a heat dissipation channel alone, so that they do not affect each other, effectively preventing the heat generated by individual energy storage batteries from being transferred to other energy storage batteries, causing thermal runaway of other energy storage batteries.

[0017] An installation cavity 15 is provided between the top of the cluster rack 3 and the inner wall of the cabinet 1, and a cooling mechanism is provided in the installation cavity 15. The cooling mechanism includes a heat exchanger 16, an infusion pump 17 and a condenser 18. The heat exchanger 16 is connected to one end of the condenser 18, the liquid outlet end of the infusion pump 17 is connected to the other end of the condenser 18, the liquid inlet end of the infusion pump 17 is connected to the heat exchanger 16 through a connecting pipe, and the condenser 18 is provided in the cooling cavity 4.

[0018] like Figure 2 As shown, when the wind outside the cabinet 1 enters the cooling chamber 4, the wind in the cooling chamber 4 is cooled by the condenser 18, and the cooled wind contacts the energy storage battery to cool it, thereby improving the heat dissipation effect. The coolant is cooled by the heat exchanger 16 and then drawn into the condenser 18 by the infusion pump 17 to exchange heat with the wind in the cooling chamber 4, and then the coolant in the condenser 18 is cooled by the heat exchanger 18 again, thereby circulating to cool the wind in the cooling chamber 4.

[0019] A sealing door 19 is provided on one side of the cabinet 1 , and a sealing plate 20 adapted to the opening end of the accommodating cavity 9 is fixedly connected to the inner wall of the sealing door 19 , and the sealing plate 20 is connected to the opening end of the accommodating cavity 9 via an elastic sealing gasket.

[0020] like Figure 1 As shown, the sealing door 19 is hinged to the cabinet 1. When the sealing door 19 is closed, the sealing plate 20 on the sealing door 19 seals the open end of the accommodating chamber 9, so that the accommodating chamber 9 is in a closed state when the sealing door 19 is closed, which can ensure the passage path of cold air and prevent heat from entering other accommodating chambers 9 and affecting the normal operation of other energy storage batteries. The elastic sealing gasket can be fixedly connected to the opening of the accommodating chamber 9, or fixedly connected to the surrounding of the sealing plate 20. The material of the elastic sealing gasket can be selected from a fluororubber material that is elastic and resistant to high temperature to improve its sealing performance.

[0021] An explosion-proof valve is arranged on the energy storage battery and located on one side of the exhaust cavity. The explosion-proof valve is connected to the exhaust cavity through a ventilation pipe.

[0022] like Figure 3 As shown, the explosion-proof valve can quickly release pressure to maintain pressure balance, avoid explosion of the energy storage battery, and discharge the released pressure gas into the exhaust chamber, which is then discharged to the outside of the cabinet 1 by the exhaust fan 14.

[0023] A heat-insulating cotton pressing plate is provided on the top of the top plate 7 .

[0024] like Figure 3 As shown, the heat-insulating pressure plate can prevent the heat in the heat dissipation cavity 10 from being transferred to the adjacent accommodating cavity 9 and affecting the adjacent energy storage batteries.

[0025] Principle of use: The exhaust fan 14 draws air from the louvered air outlet 5 into the cooling chamber 4, where it is cooled by the condenser 18. The cooled air passes through the energy storage battery from the air inlet 12, and exchanges heat with the heat on the energy storage battery. The cold air absorbs the heat of the battery to form hot air, which enters the exhaust chamber 6 along the heat dissipation holes 11 and the vents 13. The exhaust fan 14 discharges the air in the exhaust chamber 6 out of the cabinet 1.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
