Description

Technical Field

[0001] This utility model relates to the field of electrical box technology, and in particular to an explosion-proof heat dissipation box for microgrid energy storage. Background Technology

[0002] With increasing global emphasis on environmental protection and sustainable development, the energy sector is undergoing a profound transformation. The finite nature of traditional fossil fuels and their negative environmental impacts during use have prompted countries to vigorously develop renewable energy. These distributed energy sources are characterized by intermittency and instability. To achieve a stable energy supply, microgrid technology has emerged. As a relatively independent and self-controlled small-scale power system, a microgrid can organically combine distributed energy sources, energy storage devices, loads, and control equipment to achieve on-site energy production, storage, and consumption. Energy storage systems play a core role in microgrids. They can store electrical energy when there is excess distributed energy generation and release electrical energy when there is insufficient generation and during peak load periods, thus smoothing power fluctuations, regulating grid frequency, improving power quality, and enhancing grid reliability. To meet the stringent safety and heat dissipation requirements of microgrid energy storage systems, the development of explosion-proof heat dissipation enclosures has become inevitable.

[0003] The structure of an explosion-proof heat dissipation enclosure includes a cabinet, cabinet door, heat dissipation device, electrical equipment mounting bracket, grounding system, and lightning protection device. The energy storage system consists of a large number of battery packs. During the charging and discharging process, batteries are at risk of thermal runaway, overcharging, over-discharging, and short circuits. These risks can cause fires or even explosions. Once an explosion occurs in the energy storage system, it will trigger a chain reaction, causing extremely serious casualties and property damage. Existing technologies can effectively prevent the spread of explosions occurring inside the enclosure by using special materials, structural designs, and heat dissipation technologies. However, the internal space of the explosion-proof enclosure is fixed, making it difficult to adapt to the installation needs of equipment of different sizes and quantities, and failing to make full use of the internal space, resulting in low space utilization.

At the same time, the sealing sleeve can prevent heat from being lost to other areas inside the enclosure during ventilation, avoid heat backflow, ensure that the discharged heat can be effectively transferred to the outside, and reduce the inflow of external heat.

[0035] Please see the appendix Figure 1 - Appendix Figure 3 An anti-slip pad 15 is fixedly connected to the bottom of the explosion-proof enclosure 1. A door 16 is rotatably connected to the left front end of the explosion-proof enclosure 1. A controller 22 is fixedly connected to the right side of the explosion-proof enclosure 1.

A controller 22 is fixedly connected to the right side of the explosion-proof enclosure 1, which is electrically connected to the motor 4 and the air cooler 202 respectively, to ensure the efficient operation of the motor 4 and the air cooler 202 to meet the adjustment and heat dissipation requirements inside the explosion-proof enclosure. The transparent observation panel 18 allows the operating status of the equipment inside the enclosure to be observed without opening the enclosure door 16, which facilitates daily monitoring and maintenance.

[0037] Please see the appendix Figure 1 - Appendix Figure 3 A handle 19 is fixedly connected to the front right side of the door 16, a nameplate 20 is fixedly connected to the front top of the door 16, a handle 13 is fixedly connected to the front of the latch 12, a sealing strip 14 is fixedly connected to the front of the explosion-proof enclosure 1, and multiple breathing lights 21 are fixedly connected to the right top of the explosion-proof enclosure 1.

[0039] Working principle: The motor 4 drives the threaded rod 5 to rotate, thereby moving the connecting frame 6 left and right, and then moving the partition plate 7, realizing the adjustment of the internal space of the explosion-proof enclosure 1. The motor 4 drives the automatic adjustment process, eliminating the need for manual operation, reducing labor intensity, improving work efficiency, and making the adjustment process more stable and reliable. At the same time, the position of the moving support plate 10 can be manually adjusted, and then the clamping frame 12 passes through the corresponding hole 9 and engages with the positioning hole 11 to fix the support plate 10, thereby further adjusting the internal space of the explosion-proof enclosure 1. It can make full use of the internal space of the explosion-proof enclosure 1. The position and spacing of the support plate 10 can be adjusted according to the size and shape of different equipment, so that the equipment can be installed and arranged more reasonably, improving space utilization and helping to reduce the footprint of the energy storage system.

[0040] The heat absorption plate 203 absorbs heat from inside the explosion-proof enclosure 1, effectively reducing the internal temperature. The hot air is then continuously blown out by the cooler 202 and discharged through the ventilation duct 204, forming forced convection to accelerate the discharge of hot air and improve heat dissipation efficiency. This allows heat to be dissipated to the external environment more quickly, maintaining the internal temperature of the explosion-proof enclosure 1 within a safe range. At the same time, the sealing sleeve 205 on the outer wall of the ventilation duct 204 prevents heat from being lost to other areas inside the enclosure during ventilation, avoiding heat backflow and ensuring that the discharged heat is effectively transferred to the outside. It also plays a certain role in heat insulation, reducing the ingress of external heat. The filter 206 in the middle prevents dust from accumulating on the equipment and affecting the heat dissipation effect. Meanwhile, the heat dissipation fins 207 on the rear side of the explosion-proof enclosure 1 further improve the heat dissipation effect, helping to quickly dissipate the heat inside the enclosure to the surrounding environment.
