Description

TECHNICAL FIELD

[0001] The utility model belongs to the energy storage technical field relates to the air -cooled transformer energy storage converter cabinet. BACKGROUND

[0002] Energy storage converter, also known as bidirectional energy storage inverter, is the core component of the energy storage system and the power grid to realize the two-way flow of electric energy, used for controlling the charging and discharging process of the battery, converting AC and DC, and is also an important part of the photovoltaic energy storage system. The energy storage converter cabinet is equipped with an energy storage converter, and the battery, transformer and other components can work together in the cabinet to coordinate and control the entire energy storage system. In the prior art, the energy storage converter and the transformer will inevitably generate a large amount of heat during operation, which greatly affects the working efficiency of the entire machine, and even causes great safety hazards. Therefore, how to reduce the temperature of the entire machine has always been an important design part of the energy storage converter cabinet.

[0003] In the prior art, when the temperature of the energy storage converter and the transformer is high, the temperature of the energy storage converter and the transformer is often reduced by replacing a high-power fan or installing an air conditioner outside to reduce the ambient temperature. This cooling method needs to increase energy consumption to reduce the temperature of the components themselves or the surrounding environment. Although this method can reduce the temperature, it increases energy consumption and the user's use cost, which is not economical and practical. In addition, the cooling method is not environmentally friendly and is contrary to the concept of energy storage and environmental protection.

[0004] Without increasing the cost, improving the cooling efficiency and letting the wind carry more heat, i.e. improving the heat exchange rate, becomes the key to solving the problem. Heat exchange is mainly related to three factors, namely temperature difference, heat transfer coefficient and contact area. In the cabinet, the heat transfer coefficient is fixed, so the temperature difference and the contact area are mainly improved to improve the heat exchange rate. Some patents improve the temperature difference to increase the heat exchange efficiency, such as CN214045402U discloses an energy storage converter cabinet. The small heat generating converter and off-grid switching module are located in the upper cavity, and the air flow directly enters the third air inlet and is discharged from the air outlet for heat dissipation. The large heat generating transformer and other modules are arranged in the lower cavity, and the air flow entering the first air inlet and the second air inlet is guided by the heat sink and discharged from the air outlet. However, in practical work, due to the high temperature of the transformer, part of the air flow cannot exchange heat with the transformer in the relatively spacious space, causing hot air backflow, which greatly interferes with heat exchange and cannot achieve effective cooling and heat dissipation.
