Description

Technical Field

[0001] The present invention relates to the technical field of energy storage cabinets, and in particular to an air-cooled integrated energy storage cabinet. Background Art

[0002] Energy storage cabinet is a device for storing electric energy. It uses advanced energy storage technology to store electric energy when the power supply is sufficient, and release electric energy when the demand is peak or the power is insufficient. The energy storage cabinet is mainly composed of cabinet, battery pack, converter, high-voltage box, control box and other components. The energy storage cabinet has the advantages of high energy density, fast response and long life, and has become a key component of modern energy system.

[0003] At present, there are two types of energy storage cabinets commonly used in the market: one is air-cooled and the other is liquid-cooled. The existing air-cooled energy storage cabinets have the following defects in actual use: the air-cooled energy storage cabinets use heat exchangers or air conditioners to dissipate heat, which leads to incomplete and uneven heat dissipation when the heat load is high, and the installation and arrangement are more difficult and the cost is high. Conventional air ducts or no air ducts will cause excessive cold air loss and poor heat dissipation effect.

[0004] For example, there is a utility model patent with application number 202323355319X, named "A kind of air-cooled energy storage cabinet". In this patent, an electrical box is arranged at the lower part of the cabinet and a battery pack is arranged at the upper part. This arrangement will lead to incomplete and unbalanced heat dissipation and poor heat dissipation effect. Summary of the invention

[0005] In view of the problems and shortcomings of the prior art, the present invention provides a novel air-cooled energy storage integrated cabinet.

[0006] The present invention solves the above technical problems through the following technical solutions:

[0007] The present invention provides an air-cooled energy storage integrated cabinet, which is characterized in that it includes an energy storage cabinet body, wherein the energy storage cabinet body is divided into a battery pack placement area, an air duct placement area and an electrical placement area from bottom to top, wherein a plurality of horizontally placed air-cooled battery packs are fixed in the energy storage cabinet body and in the battery pack placement area, an air conditioning air duct is fixed in the energy storage cabinet body and in the air duct placement area, and a horizontally placed energy storage converter, a high-voltage box and a control box are fixed in the energy storage cabinet body and in the electrical placement area, wherein a plurality of the air-cooled battery packs are sequentially connected through copper bars. In series, a hood and an industrial air conditioner are embedded in the back of the energy storage cabinet, a plurality of heat dissipation holes are opened at the bottom of the hood, an electrical air duct is fixed in the energy storage cabinet and at the rear side of the electrical placement area, a heat dissipation fan is fixed on the inner side of the hood, the heat dissipation fan faces the electrical air duct, the inner circulation air outlet of the industrial air conditioner faces the battery pack placement area, and the inner circulation return air outlet faces the air duct placement area, a smoke detector and a temperature detector are fixed in the energy storage cabinet, and an aerosol fire extinguishing device is fixed on the front and rear sides of the energy storage cabinet respectively;

[0008] The temperature detector is used to detect the temperature inside the energy storage cabinet and transmit it to the control box. The control box is used to control the industrial air conditioner to turn on when the detected temperature inside the energy storage cabinet is higher than the first set temperature. The cold air blown out of the internal circulation air outlet of the industrial air conditioner blows toward the battery pack placement area. The hot air in the battery pack placement area rises to the air duct of the air conditioner and is sucked into the industrial air conditioner by the internal circulation return air outlet of the industrial air conditioner. The hot air in the battery pack placement area flows out of the energy storage cabinet through the external circulation return air outlet of the industrial air conditioner. When the detected temperature inside the energy storage cabinet is not higher than the first set temperature, the industrial air conditioner is controlled to turn off.

[0009] The IGBT in the energy storage converter senses the temperature and transmits it to the control box, and the control box is used to control the cooling fan to turn on when the temperature sensed by the IGBT is higher than the second set temperature so as to dissipate the heat in the electrical installation area through the electrical air duct and the heat dissipation holes at the bottom of the air cover, and control the cooling fan to turn off when the temperature sensed by the IGBT is not higher than the second set temperature;

[0010] The smoke detector is used to detect the smoke concentration signal in the energy storage cabinet and transmit it to the control box. The control box is used to control the two aerosol fire extinguishing devices to open when the detected smoke concentration signal reaches a set concentration value so that the aerosol fire extinguishing devices perform a fire extinguishing operation.

[0011] The positive and progressive effect of the present invention is that: the arrangement of the present invention is to divide the energy storage cabinet into a battery pack placement area, an air duct placement area and an electrical placement area from bottom to top, the battery pack placement area is used to place multiple horizontally placed air-cooled battery packs, the air duct placement area is used to place air conditioning ducts, and the electrical placement area is used to place horizontally placed high-voltage boxes, control boxes and energy storage converters. When the temperature in the energy storage cabinet is high, the industrial air conditioner is turned on, and the cold air blown out of the internal circulation air outlet of the industrial air conditioner blows toward the battery pack placement area, and the hot air in the battery pack placement area rises to the air conditioning duct, is sucked into the industrial air conditioner by the internal circulation return air outlet of the industrial air conditioner, and flows to the outside of the energy storage cabinet through the external circulation return air outlet of the industrial air conditioner; in the present invention, the IGBT in the energy storage converter is used to sense the temperature. When the temperature sensed by the IGBT is high, the heat dissipation fan is turned on to dissipate the heat in the electrical placement area through the electrical duct and through the heat dissipation holes at the bottom of the wind cover. The arrangement of the energy storage cabinet of the present invention is conducive to heat dissipation, so that the heat dissipation is comprehensive and balanced, and the heat dissipation effect is good, thereby reducing the cost.
