Description

Technical Field

[0001] This utility model relates to the field of energy storage cabinet technology, specifically to a transformer heat dissipation structure inside an energy storage cabinet that is easy to maintain. Background Technology

[0002] Commercial and industrial photovoltaic-energy storage integrated systems are devices that integrate photovoltaic power generation and energy storage systems. They combine solar photovoltaic power generation and energy storage technologies to improve energy self-sufficiency, reduce dependence on the power grid, and provide clean power for devices in various scenarios.

[0003] During operation, the isolation transformer of a commercial and industrial integrated photovoltaic energy storage unit generates a large amount of heat. If this heat is not dissipated in time, it will affect the operation of the unit, accelerate the aging of internal cables, reduce their service life, and in severe cases, cause fires and significant losses. Currently, to save space, most commercial and industrial integrated photovoltaic energy storage units choose to install the transformer vertically in the cabinet. However, some isolation transformers are installed horizontally, and since isolation transformers are generally heavy, vertical installation can lead to installation difficulties. Therefore, it is necessary to study a transformer heat dissipation structure that is easy to maintain within the energy storage cabinet. Utility Model Content

[0025] The air intake assembly includes a removable cover plate 8, which is installed on the surface of the waterproof frame 4. The surface of the removable cover plate 8 has several ventilation openings and fixing holes. The inner wall of the removable cover plate 8 is fitted with a ventilation hood 9 by nuts, and the ventilation hood 9 is connected to the ventilation openings. The ventilation openings of the ventilation hood 9 are equipped with air intake dustproof nets 10, which are made of aluminum alloy frames and filled with polyurethane flame-retardant filter cotton, thereby effectively preventing external dust from entering the interior of the energy storage cabinet 1. Z-shaped handles 15 are symmetrically arranged on the surface of the air intake dustproof nets 10.

[0026] refer to Figure 7 A flame-retardant sealing strip 11 is affixed to the mating surface between the waterproof frame 4 and the air intake component.

[0027] As a technical optimization of this utility model, the flame-retardant sealing strip 11 can prevent rainwater from entering the interior of the energy storage cabinet 1 through the gap between the waterproof frame 4 and the air inlet component.

[0028] refer to Figure 7The inner wall of the waterproof frame 4 has several mounting holes, and the internal threads of the mounting holes are connected to stainless steel combination bolts 12, which are used in conjunction with the air intake assembly.

[0029] As a technical optimization of this utility model, the installation holes and stainless steel combination bolts 12 can improve the firmness of the waterproof frame 4 and the air intake component after installation, and can also help support the weight of the air intake component.

[0030] refer to Figure 7 Structural adhesive is applied to the edges of the ventilation hood 9.

[0031] As a technical optimization of this utility model, the use of structural adhesive prevents rainwater from seeping into the interior of the energy storage cabinet 1 through the installation gaps of the ventilation cover 9.

[0032] refer to Figure 4 The air outlet below the rain cover 7 is equipped with an air outlet dustproof net 13.

[0033] As a technical optimization of this utility model, the dustproof net 13 can achieve the effect of dust prevention and prevent small animals from entering the interior of the energy storage cabinet 1 through the rain cover 7.

[0035] As a technical optimization of this utility model, by setting up ventilation louvers 14, the inclined design of ventilation louvers 14 can effectively drain rainwater to the outside of the energy storage cabinet 1, thus achieving the purpose of waterproofing.

[0036] The usage process of this utility model is as follows: When installing the air inlet dustproof net 10, the air inlet dustproof net 10 is inserted into the groove of the ventilation cover 9 on one side and fixed with two Z-shaped handles 15 on the other side. When removing it for cleaning, simply rotate the two Z-shaped handles 15 first, and then pull the air inlet dustproof net 10 out of the groove of the ventilation cover 9. The disassembly process is simple and convenient. When installing the air outlet dustproof net 13, push the air outlet dustproof net 13 directly into the groove of the rainproof cover 7.

[0037] If the isolation transformer 2 is only suitable for vertical installation, simply open the door panel 5 on the back of the energy storage cabinet 1 and push the isolation transformer 2 from the door frame into the energy storage cabinet 1 for installation. If the isolation transformer 2 is only suitable for horizontal installation, simply remove the air intake component on the side of the energy storage cabinet 1 and push the isolation transformer 2 into the energy storage cabinet 1 through the air intake for installation. Furthermore, regardless of the installation method of the isolation transformer 2, when the wiring or operation of the isolation transformer 2 needs to be repaired, simply remove the air intake component on the side of the energy storage cabinet 1, which makes the installation and maintenance of the isolation transformer 2 more convenient.
