Description

Technical Field

[0001] This application relates to the field of fire protection technology, specifically to a directional explosion relief system and an energy storage cabinet. Background Technology

[0002] In existing energy storage systems, the instantaneous generation of high-temperature gases during thermal runaway of battery cells causes a surge in pressure within the battery compartment. To prevent the battery compartment from rupturing, a pressure relief structure is installed on the outer shell to release the gases generated by the cells. However, existing pressure relief structures directly connect the inside and outside of the battery compartment. During the pressure relief process, the ejected high-temperature gases can damage other battery compartments and functional components, potentially causing thermal runaway of cells in other battery compartments and other system malfunctions, posing a significant safety hazard. Utility Model Content

[0003] In view of this, this application provides a directional explosion relief system and energy storage cabinet, which can realize directional explosion relief and improve the explosion relief safety of the system.

[0004] To achieve the above objectives, this application provides the following technical solution: A directional explosion relief system includes multiple electrical modules and a fan stacked along a first direction; The electrical module includes an electrical chamber for housing electrical components and a first air duct and a second air duct that communicate with each other. The first air duct is located on a first side of the electrical chamber in the first direction, and the second air duct is perpendicular to the first air duct. The second air duct extends along the first direction and is disposed on a second side of the electrical chamber. A pressure relief structure communicating with the electrical chamber is disposed in the second air duct. The fan is used to provide power for the airflow within the first and second air ducts.

[0013] An energy storage cabinet includes a directional explosion venting system as described in any of the preceding claims, wherein the electrical components include battery cells.

[0014] The directional explosion relief system and energy storage cabinet provided in this application, when the system is operating normally, the fan starts and drives air through the first and second air ducts, carrying away heat from the first and second sides of the electrical chamber, thus ventilating and dissipating heat from the electrical chamber. When the system is operating abnormally, a large amount of high-temperature gas is generated in the electrical chamber. The pressure inside the electrical chamber reaches the threshold of the pressure relief structure and breaks through the pressure relief structure. The high-temperature gas is discharged into the second air duct. At the same time, the fan drives air through the first and second air ducts in sequence. When the air passes through the pressure relief structure, it carries away the high-temperature gas discharged by the pressure relief structure, thus directionally ventilating the electrical chamber.

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] like Figures 1-16 As shown, this application embodiment provides a directional explosion relief system, including multiple electrical modules and a fan. The number of electrical modules can be set to two, three, four or more. The multiple electrical modules are stacked along a first direction. Here, the first direction is taken as the vertical direction for example. That is, multiple electrical modules are stacked in the vertical direction to form the whole of the directional explosion relief system.

[0035] The electrical module includes an electrical chamber 1 and a heat dissipation duct. The electrical chamber 1 houses electrical components, which may include battery cells and circuit boards, as well as other heat-dissipating electrical components such as power semiconductors and magnetic devices. This example uses a battery cell housed within the electrical chamber 1. The heat dissipation duct and the electrical chamber 1 are sealed and isolated from each other. The heat dissipation duct is used to ventilate and dissipate heat from the electrical chamber 1. The heat dissipation duct can be located either inside or outside the electrical chamber 1.

[0036] The heat dissipation duct includes a first duct 3 and a second duct 4 that are interconnected. The first duct 3 is located on a first side of the electrical chamber 1 in a first direction, for example, above or below the electrical chamber 1. When multiple electrical modules are stacked, the first duct 3 and the electrical chamber 1 are staggered in the first direction to facilitate heat dissipation from the first duct 3 to adjacent electrical chambers 1. The second duct 4 is located on one side of the electrical chamber 1 in a second direction (i.e., the second side of the electrical chamber 1). Here, the first direction is defined as perpendicular to the second direction, i.e., the second direction is horizontal, so that the first duct 3 and the second duct 4 are perpendicular. When multiple electrical modules are stacked, multiple second ducts 4 are arranged and connected along the first direction to connect the heat dissipation ducts in adjacent electrical modules, which is beneficial for directional heat dissipation and ventilation.

[0037] Furthermore, a pressure relief structure 6 is installed in the second air duct 4 to connect the second air duct 4 to the electrical chamber 1. When the system is operating normally, the fan 7 starts and drives air through the first air duct 3 and the second air duct 4, carrying away the heat on the first and second sides of the electrical chamber 1, thereby ventilating and dissipating heat from the electrical chamber 1. When the system is operating abnormally, a large amount of high-temperature gas is generated in the electrical chamber 1. The pressure in the electrical chamber 1 reaches the threshold of the pressure relief structure 6 and breaks through the pressure relief structure 6. The high-temperature gas is discharged into the second air duct 4. At the same time, the fan 7 drives air through the first air duct 3 and the second air duct 4 in sequence. When the air passes through the pressure relief structure 6, it carries away the high-temperature gas discharged by the pressure relief structure 6, thereby directional deflation of the electrical chamber 1.

[0038] In the specific scheme, in order to improve the heat dissipation effect in the first air duct 3, a heat dissipation fin 5 is provided inside the first air duct 3. The heat dissipation fin 5 is thermally connected to the electrical chamber 1 so that the heat dissipation fin 5 can dissipate heat from the electrical chamber 1. When the system is running normally, the fan 7 starts and drives the air through the first air duct 3 and the second air duct 4 in sequence. When the air passes through the heat dissipation fin 5 in the first air duct 3, it carries away the heat on the heat dissipation fin 5, thereby ventilating and dissipating heat from the electrical chamber 1.

[0039] With this configuration, the pressure relief structure 6 is placed inside the heat dissipation duct. The high-temperature gas generated in the electrical chamber 1 is first discharged into the heat dissipation duct through the pressure relief structure 6, and then released in a directional manner with the ventilation of the heat dissipation duct. This can prevent the high-temperature gas from damaging other external components, improve system safety, and also realize the integrated design of fire protection and ventilation, which is conducive to simplifying the system structure.

[0040] It is understandable that the aforementioned heat dissipation duct and fan 7 both belong to the heat dissipation system. The fan 7 can be located inside or outside the heat dissipation duct, as long as it can drive air to flow sequentially through the first duct 3 and the second duct 4. Specifically, a first air outlet is provided on the first duct 3 at a position away from the second duct 4, and a second air outlet is provided on the second duct 4 at a position away from the first duct 3. The first air outlet can be used for air intake and air exhaust. When the first air outlet is used for air intake, the fan drives air to flow sequentially through the first air outlet, the first duct, the second duct, and the second air outlet. When the first air outlet is used for air exhaust, the fan drives air to flow sequentially through the second air outlet, the second duct, the first duct, and the first air outlet.

[0041] Here, in order to facilitate the arrangement of electrical components in the electrical chamber 1, the electrical chamber 1 is set in a cuboid shape. The first air duct 3 is located at the bottom of the electrical chamber 1 and is also set in a cuboid shape. The first side of the first air duct 3 is connected to the second air duct 4, and the second side is provided with a first air outlet. The first side and the second side can be two opposite sides or two adjacent sides.

[0042] In some embodiments, this directional explosion relief system further includes a heat dissipation module 2, which is stacked with multiple electrical modules, for example, the heat dissipation module 2 is located on top of multiple electrical modules. A third air duct is provided on the heat dissipation module 2, which connects to and communicates with the second air outlet of the second air duct 4 of the adjacent electrical modules, so that the second air ducts 4 of multiple electrical modules are all connected to the third air duct. A fan 7 is installed inside the third air duct. Driven by the fan 7, air sequentially passes through the first air duct 3, the second air duct 4, and the third air duct, and is discharged from the third air duct. Furthermore, by adjusting the installation direction of the fan 7, the fan 7 can drive air sequentially through the third air duct, the second air duct 4, and the first air duct 3, and be discharged from the first air duct 3. Thus, by placing the fan 7 inside the heat dissipation module 2 and separating it from the electrical modules, one fan 7 can drive the ventilation of the third air ducts of multiple electrical modules, which helps reduce the number of fans 7 used, simplifies the structure, and reduces the product failure rate.

[0043] A noise reduction structure is installed between the fan 7 and the third air duct. This noise reduction structure can be made of sound-absorbing cotton to reduce the operating noise of the fan 7.

[0044] In other embodiments, the directional explosion relief system may not include the heat dissipation module 2. The fan 7 is installed within the electrical module, that is, the fan 7 is installed within the first air duct 3 or the second air duct 4. For example, the fan 7 can be installed at the first air outlet of the first air duct 3, the second air outlet of the second air duct 4, or at the connection point between the first air duct 3 and the second air duct 4. In this way, multiple electrical modules can be freely assembled without needing to be compatible with the heat dissipation module 2, which simplifies the assembly process.

[0045] A noise reduction structure is provided between the fan 7 and the first air duct 3, or between the fan 7 and the second air duct 4. This noise reduction structure can be made of sound-absorbing cotton, thereby reducing the operating noise of the fan 7.

[0046] The following is a detailed description of this directional explosion relief system with reference to the accompanying drawings.

[0047] like Figure 1 , 9 As shown in Figures 1 and 10, in the first embodiment, the directional explosion relief system includes a heat dissipation module 2 and multiple electrical modules arranged sequentially from top to bottom. The heat dissipation module 2 is provided with a third air duct, and a fan 7 is installed inside the third air duct. A noise reduction structure is provided between the fan 7 and the third air duct. The noise reduction structure can be set as sound-absorbing cotton, thereby reducing the noise of the fan 7.

[0048] The electrical module includes a sealed and isolated electrical chamber 1 and a heat dissipation duct. The heat dissipation duct is located inside the electrical chamber 1 and includes a first duct 3 and a second duct 4 that are connected. The first duct 3 is located at the bottom of the electrical chamber 1. For example, a partition is provided at the bottom of the electrical chamber 1, and the first duct 3 is formed between the partition and the bottom shell of the electrical chamber 1. The second duct 4 is located on the left side of the electrical chamber 1. For example, a ventilation duct connected to the first duct 3 is provided on the left side of the electrical chamber 1, and the second duct 4 is formed inside the ventilation duct.

[0049] The first air duct 3 is equipped with heat dissipation fins 5 for cooling the electrical chamber 1. The first air outlet of the first air duct 3 and the second air duct 4 are located on opposite sides of the first air duct 3, i.e., the first air outlet of the first air duct 3 is located on the right side of the electrical chamber 1, so that the air inlet direction of the first air duct 3 is parallel to the air outlet direction of the first air duct 3. The second air outlet of the second air duct 4 is located at the top of the electrical chamber 1. The second air duct 4 is equipped with a pressure relief structure 6, which can be configured as a pressure relief valve. The second air duct 4 is connected to the electrical chamber 1 through the pressure relief structure 6. The pressure relief structure 6 can release the high-temperature gas in the electrical chamber 1 into the second air duct 4, and then, driven by the fan 7, it is discharged through the second air outlet and the third air duct of the second air duct 4, improving the safety of pressure relief. In addition, by adjusting the installation direction of the fan 7, the high-temperature gas driven by the fan 7 can also be discharged through the first air outlet of the first air duct 3.

[0050] like Figure 2 , 10 As shown in Figure 11, in the second embodiment, the directional explosion relief system includes a heat dissipation module 2 and multiple electrical modules arranged sequentially from top to bottom. The difference between the second embodiment and the first embodiment is that the first air outlet of the first air duct 3 and the second air duct 4 are located on adjacent side surfaces of the first air duct 3, i.e., the first air outlet of the first air duct 3 is located on the front or rear side of the electrical chamber 1, so that the air inlet direction of the first air duct 3 is parallel to the air outlet direction of the first air duct 3. Here, the heat dissipation fins 5 can be configured with a curved shape according to the location of the first air outlet of the first air duct 3, so that the air can carry away the heat from the heat dissipation fins 5 when passing through the first air duct 3.

[0051] like Figure 3 , 9As shown in Figures 1 and 12, in the third embodiment, the directional explosion relief system includes multiple electrical modules arranged sequentially from top to bottom. The difference between the third and first embodiments is that the fan 7 is located within the electrical modules, specifically within the first air duct 3 and close to the second air duct 4. This allows for free assembly of multiple electrical modules without requiring compatibility with the heat dissipation module 2, simplifying the assembly process. A noise reduction structure, which can be made of sound-absorbing cotton, is provided between the fan 7 and the first air duct 3 to reduce the operating noise of the fan 7.

[0052] like Figure 4 , 11 As shown in Figures 1 and 12, in the fourth embodiment, the directional explosion relief system includes multiple electrical modules arranged sequentially from top to bottom. The difference between the fourth and third embodiments is that the first air outlet of the first air duct 3 and the second air duct 4 are located on adjacent side surfaces of the first air duct 3, i.e., the first air outlet of the first air duct 3 is located on the front or rear side of the electrical chamber 1, so that the air inlet direction of the first air duct 3 is parallel to the air outlet direction of the first air duct 3. Here, the heat dissipation fins 5 can be configured with a curved shape according to the location of the first air outlet of the first air duct 3, so that the air can carry away the heat from the heat dissipation fins 5 when passing through the first air duct 3.

[0053] like Figure 5 , 13 As shown in Figure 14, in the fifth embodiment, the directional explosion relief system includes a heat dissipation module 2 and multiple electrical modules arranged sequentially from top to bottom. The heat dissipation module 2 is provided with a third air duct, and a fan 7 is installed inside the third air duct. A noise reduction structure is provided between the fan 7 and the third air duct. The noise reduction structure can be set as sound-absorbing cotton, thereby reducing the noise of the fan 7.

[0054] The electrical module includes a sealed and isolated electrical chamber 1 and a heat dissipation duct. The heat dissipation duct is located outside the electrical chamber 1 and includes a first duct 3 and a second duct 4 that are connected. The first duct 3 is located below the electrical chamber 1. For example, the bottom shell of the electrical chamber 1 and the bottom shell of the electrical module are spaced apart and form the first duct 3 between them. The second duct 4 is located on the right side of the electrical chamber 1. For example, the right shell of the electrical chamber 1 and the right shell of the electrical module are spaced apart and form the second duct 4 between them.

[0055] The first air duct 3 is equipped with heat dissipation fins 5 for cooling the electrical chamber 1. The first air outlet of the first air duct 3 and the second air duct 4 are located on opposite sides of the first air duct 3, i.e., the first air outlet of the first air duct 3 is located on the left side of the electrical module, so that the air inlet direction of the first air duct 3 is parallel to the air outlet direction of the first air duct 3. The second air outlet of the second air duct 4 is located on the top of the electrical module. The second air duct 4 is equipped with a pressure relief structure 6, which can be configured as a pressure relief valve. The second air duct 4 is connected to the electrical chamber 1 through the pressure relief structure 6. The pressure relief structure 6 can release the high-temperature gas in the electrical chamber 1 into the second air duct 4, and then, driven by the fan 7, it is discharged through the second air outlet and the third air duct of the second air duct 4, improving the safety of pressure relief. In addition, by adjusting the installation direction of the fan 7, the high-temperature gas driven by the fan 7 can also be discharged through the first air outlet of the first air duct 3.

[0056] like Figure 6 , 14 As shown in Figure 15, in the sixth embodiment, the directional explosion relief system includes a heat dissipation module 2 and multiple electrical modules arranged sequentially from top to bottom. The difference between the sixth and fifth embodiments is that the first air outlet of the first air duct 3 and the second air duct 4 are located on adjacent side surfaces of the first air duct 3, i.e., the first air outlet of the first air duct 3 is located on the front or rear side of the electrical modules, so that the air inlet direction of the first air duct 3 is parallel to the air outlet direction of the first air duct 3. Here, the heat dissipation fins 5 can be configured with a curved shape according to the location of the first air outlet of the first air duct 3, so that the air can carry away the heat from the heat dissipation fins 5 when passing through the first air duct 3.

[0057] like Figure 7 , 13 As shown in Figure 16, in the seventh embodiment, the directional explosion relief system includes multiple electrical modules arranged sequentially from top to bottom. The difference between the seventh and fifth embodiments is that the fan 7 is located within the electrical modules, specifically within the first air duct 3 and close to the second air duct 4. This allows for free assembly of multiple electrical modules without requiring compatibility with the heat dissipation module 2, simplifying the assembly process. A noise reduction structure, which can be made of sound-absorbing cotton, is provided between the fan 7 and the first air duct 3 to reduce the operating noise of the fan 7.

[0058] like Figure 8 , 15As shown in Figure 16, in the eighth embodiment, the directional explosion relief system includes multiple electrical modules arranged sequentially from top to bottom. The difference between the eighth and seventh embodiments is that the first air outlet of the first air duct 3 and the second air duct 4 are located on adjacent side surfaces of the first air duct 3, i.e., the first air outlet of the first air duct 3 is located on the front or rear side of the electrical modules, so that the air inlet direction of the first air duct 3 is parallel to the air outlet direction of the first air duct 3. Here, the heat dissipation fins 5 can be configured with a curved shape according to the location of the first air outlet of the first air duct 3, so that the air can carry away the heat from the heat dissipation fins 5 when passing through the first air duct 3.

[0059] It should be noted that the "parallel condition" in this application refers to one direction being parallel to another, but it is not limited to the two being absolutely parallel. For example, one direction may be nearly parallel to the other, which is defined here as an angle of less than 2 degrees. The "perpendicular condition" in this document refers to one direction being perpendicular to another, but it is not limited to the two being absolutely perpendicular. For example, one direction may be nearly perpendicular to the other, which is defined here as an angle of less than 92 degrees and greater than 88 degrees.

[0060] This application provides an energy storage cabinet, including the directional explosion relief system described in the above embodiments. The directional explosion relief system has multiple stacked electrical modules, each including an electrical chamber 1 and a heat dissipation duct. Electrical components, including battery cells, are installed within the electrical chamber. When the system operates abnormally, thermal runaway of the battery cells in the electrical chamber 1 generates a large amount of high-temperature gas. The pressure inside the electrical chamber 1 reaches the threshold of the pressure relief structure 6 and breaks through it. The high-temperature gas is discharged into the second duct 4. Simultaneously, a fan 7 drives air through the first duct 3 and the second duct 4 in sequence. As the air passes through the pressure relief structure 6, it carries away the high-temperature gas discharged from the pressure relief structure 6, thus enabling directional explosion relief in the electrical chamber 1.

[0061] With this configuration, the pressure relief structure 6 is placed inside the heat dissipation duct. The high-temperature gas generated in the electrical chamber 1 is first discharged into the heat dissipation duct through the pressure relief structure 6, and then released in a directional manner with the ventilation of the heat dissipation duct. This can prevent the high-temperature gas from damaging other external components, improve system safety, and also realize the integrated design of fire protection and ventilation, which is conducive to simplifying the system structure.
