Description

Technical Field

[0001] This utility model relates to a heat dissipation device for an energy storage converter inside a battery energy storage box. Background Technology

[0002] With the rapid development of new energy technologies, battery storage boxes, as an important component of energy storage systems, are facing increasingly prominent heat dissipation issues. Batteries generate a large amount of heat during charging and discharging; if heat dissipation is not timely, it will not only affect the battery's lifespan but may also lead to safety accidents. Currently, common battery storage box cooling devices on the market mainly use air cooling and water cooling methods, but in practical applications, problems such as low heat dissipation efficiency and uneven heat dissipation still exist.

[0003] In summary, the existing battery energy storage box heat dissipation devices have the following problems: First, the heat dissipation efficiency of the converter is not high, and the existing heat dissipation system often cannot effectively dissipate the heat generated by the converter in a timely manner; second, the heat dissipation is uneven, resulting in uneven temperature distribution of the converter under the battery pack, which affects the battery life.

[0004] Therefore, there is an urgent need for a battery energy storage box heat dissipation device that can improve heat dissipation efficiency, achieve uniform heat dissipation, and be flexibly controlled. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a heat dissipation device for an energy storage converter inside a battery storage box. Through multiple symmetrically arranged U-shaped cooling components, each of which can be individually controlled, the heat dissipation efficiency and uniformity of the converter are improved. This objective is achieved as follows:

[0006] This utility model proposes a heat dissipation device for an energy storage converter inside a battery energy storage box, including a box assembly, a battery assembly, and a cooling assembly. The box assembly has an overall rectangular frame structure. Several battery assemblies are installed inside the box assembly, and several cooling assemblies are distributed correspondingly at the lower part of the battery assemblies. The cooling assemblies are symmetrically distributed on both sides of the box assembly. A cooling chamber is formed inside each cooling assembly. An air inlet and an air outlet are provided on the side surface of the cooling assembly, extending horizontally into the cooling chamber. The air outlet is arranged above the air inlet. Airflow passes through the air inlet and the cooling chamber and is discharged from the air outlet. A first air inlet control assembly is provided on one side of the air inlet to control the air intake, and a second air inlet control assembly is provided on one side of the air outlet to control the air outlet.

[0007] Furthermore, a partition is installed in the center of the cooling chamber to separate the corresponding cooling components on the left and right sides.

[0008] Furthermore, the cooling assembly is fixed to the inside of the housing assembly by bolts, and the battery assembly is fixed to the inside of the housing assembly by bolts.

[0009] Furthermore, a heat-conducting plate is distributed between the battery assembly and the cooling assembly, and the two sides of the heat-conducting plate are respectively connected to the battery assembly and the cooling assembly by bolts.

[0010] Furthermore, the first air intake control component includes a preset fan for supplying air into the cooling chamber, the preset fan being bolted inside the air inlet; the second air intake control component includes a preset fan assembly for exhausting air into the cooling chamber, the preset fan assembly being bolted inside the air outlet.

[0011] Furthermore, the air outlet has a rectangular cross-section, the air inlet has a rectangular cross-section, and the cross-section of the air outlet is smaller than that of the air inlet.

[0012] Furthermore, a filter plate is bolted to the air inlet and a filter plate is bolted to the air outlet.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: by symmetrically distributing the cooling components on both sides of the housing component, and setting the air inlet and air outlet on the side surface of the cooling components, the air force can be discharged from the air outlet through the air inlet and cooling chamber. At the same time, the air inlet volume and air outlet volume are controlled by the first air inlet control component and the second air inlet control component respectively, thereby increasing the heat dissipation efficiency of the converter. Each air inlet control component can be controlled separately, thereby improving the heat dissipation efficiency and uniformity. Attached Figure Description

Detailed Implementation

[0017] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0018] Please refer to Figure 1-2This utility model provides a heat dissipation device for an energy storage converter inside a battery storage box, including a box assembly 200, a battery assembly 100, and a cooling assembly 300. The box assembly 200 has a rectangular frame structure. Several battery assemblies 100 are installed inside the box assembly 200. Several cooling assemblies 300 are distributed correspondingly at the lower part of the battery assemblies 100, symmetrically distributed on both sides of the box assembly 200. A cooling chamber is formed inside each cooling assembly 300. An air inlet 350 and an air outlet 340 are provided on the side surface of each cooling assembly 300, extending horizontally into the cooling chamber. The air outlet 340 is located above the air inlet 350. Airflow passes through the air inlet 350 and the cooling chamber and is discharged from the air outlet 340. A first air inlet control assembly 310 is provided on one side of the air inlet 350 to control the air intake volume, and a second air inlet control assembly 320 is provided on one side of the air outlet 340 to control the air outlet volume. Figure 2 The arrows indicate the direction of wind circulation.

[0019] Understandably, a partition 360 is installed in the center of the cooling chamber to separate the corresponding cooling components 300 on the left and right sides. The partition 360 divides the cooling chamber into two independent spaces, which can dissipate heat from the battery components 100 on both sides respectively, improving heat dissipation efficiency and preventing heat from interfering with each other inside the cooling chamber. The cooling components 300 are fixed to the inside of the housing component 200 by bolts, and the battery components 100 are also fixed to the inside of the housing component 200 by bolts. This connection method facilitates installation and disassembly, and makes it convenient for later maintenance and replacement. A heat-conducting plate 400 is distributed between the battery components 100 and the cooling components 300. The two sides of the heat-conducting plate 400 are respectively connected to the battery components 100 and the cooling components 300 by bolts. The heat-conducting plate 400 can quickly conduct the heat generated by the battery components 100 to the cooling components 300, improving heat dissipation efficiency, ensuring that the battery components 100 operate within a suitable temperature range, and extending battery life.

[0020] Understandably, the first air intake control component 310 includes a preset fan for supplying air into the cooling chamber. The preset fan is bolted inside the air inlet 350. The second air intake control component 320 includes a preset fan assembly for exhausting air into the cooling chamber. The preset fan assembly is bolted inside the air outlet 340. The coordinated operation of the preset fan and the preset fan assembly creates forced convection, accelerating airflow within the cooling chamber and improving heat dissipation efficiency. The air outlet 340 has a rectangular cross-section, and the air inlet 350 also has a rectangular cross-section. The cross-section of the air outlet 340 is smaller than that of the air inlet 350. This design increases the air velocity at the air outlet 340 when the air flows through the cooling chamber, creating a negative pressure zone, which helps to accelerate airflow and improve heat dissipation.

[0021] It should be noted that the inverter 500 is located on the lower side of the battery pack 100, inside the cooling pack 300.

[0022] Understandably, a filter plate 370 is bolted to the air inlet 350, and a filter plate 370 is also bolted to the air outlet 340. The filter plate 370 can filter dust and impurities in the air, preventing impurities from entering the cooling chamber, keeping the cooling system clean, and extending the service life of the equipment. At the same time, the filter plate 370 is easy to clean and replace, improving the maintainability of the equipment. In actual use, when the battery assembly 100 generates heat, the heat is first transferred to the heat conduction plate 400, and then transferred by the heat conduction plate 400 to the cooling assembly 3. 00, the preset fan of the first air intake control component 310 sends external cold air into the cooling chamber, while the preset fan group of the second air intake control component 320 draws hot air out from the air outlet 340, forming forced convection and accelerating heat dissipation. Since the cross-section of the air outlet 340 is smaller than that of the air inlet 350, the air speed increases when flowing through the cooling chamber, further enhancing the heat dissipation effect. During the entire heat dissipation process, the partition 360 divides the cooling chamber into two independent spaces, so that the heat dissipation of the battery components 100 on both sides does not interfere with each other, improving the heat dissipation efficiency of the inverter 500.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
