Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation of energy storage converters, in particular to a heat dissipation structure of a high-power energy storage converter. Background Art

[0002] A high-power energy storage converter is a power electronic device used to convert the electrical energy stored in the energy storage system into AC electrical energy that can be used in the power grid or other power systems. It is mainly used for grid regulation, the application of energy storage systems, and the integration of renewable energy. This type of converter usually has the following characteristics: high power density, high efficiency, fast response, high reliability and stability, and versatility. These characteristics make high-power energy storage converters an important part of modern power systems, which can help improve the stability, flexibility and sustainability of the power grid, promote the large-scale integration of renewable energy, and support the development of power systems towards intelligence and efficiency. High-power energy storage converters generate a lot of heat during operation, mainly due to the loss of electronic devices and the conversion of energy into heat due to the resistance of the circuit. In order to avoid the internal temperature of the energy storage converter from rising, resulting in overheating and damage of electronic components, it is necessary to install a heat dissipation structure to dissipate heat, usually including heat sinks, cooling fans, radiators, etc., to ensure safety and stability during use and extend service life.

[0003] The existing Chinese patent publication number is CN219322847U, and its name is a converter and its heat dissipation structure. The fan is easy to replace, which improves the maintenance efficiency of the converter in the later stage and provides a good temperature environment for the converter to work. The ventilation of the converter can reduce dust from entering the machine, prevent internal machine damage, and increase the service life of the converter.

[0004] However, in this technology, heat is dissipated only through fans and heat sinks, resulting in low heat dissipation and slow heat dissipation, which can easily lead to device aging and reduce the service life of the device.

The circular holes in the heat sink can allow the cold air to circulate, ensuring that every position is blown by the cold air, thereby improving the heat dissipation effect; the pump body 10 is arranged in the mounting frame 3, and a cooling box 11 is arranged on one side of the pump body 10, and the inlet pipe 8 and the outlet pipe 9 are connected by a pipeline; the filter 15 is arranged on the box body 1 and the box door 2, and a limiting member is arranged in a rectangular array outside the filter 15.

[0027] Specifically, a partition plate 4 is provided between two adjacent heat sinks. The partition plate 4 is mounted on a mounting frame 3 , and the mounting frame 3 is mounted on the inner bottom of the box body 1 by screws.

[0028] In this embodiment, the partition plate 4 and the mounting frame 3 are an integrated structure, and separate the device devices installed on the mounting frame 3.

[0029] Specifically, the heat sink includes a heat sink 5, which is arranged on a mounting frame 3, and heat sink fins 6 are respectively arranged on both sides of the outside of the tube body, and the heat sink fins 6 are installed on the heat sink 5. A rectangular array of circular holes is opened on the heat sink fins 6, and an inlet pipe 8 is installed at the upper end of a plurality of cold water pipe fittings 7, and a discharge pipe 9 is installed at the lower end of a plurality of cold water pipe fittings 7, the other end of the inlet pipe 8 is installed on a cooling box 11, and the other end of the discharge pipe 9 is installed on a pump body 10.

[0030] In the present embodiment, the heat dissipation fins 6 on the outside of a cold water pipe fitting 7 are all installed on the heat dissipation plate 5 on one side thereof. The heat dissipation plate 5 and the heat dissipation fins 6 are an integrated structure. The cold water pipe fitting 7, the discharge pipe 9 and the input pipe 8 are an integrated structure.

The circular holes set can be used for the circulation of cold air to avoid the heat dissipation fins 6 blocking the cold air.

[0031] Specifically, ventilation slots 14 are respectively provided on the box body 1 and the box door 2, the filter 15 is arranged outside the ventilation slot 14, the box door 2 is provided with a control device 20, the limiting component includes a limiting block 16, a connecting block 17 is installed on the limiting block 16, and grooves adapted to the connecting block 17 are provided on the box body 1 and the box door 2.

At the same time, the cold air flows to the outside of the heat dissipation component through the circular holes opened on the heat dissipation fins 6, and the inside of the box body 1 is fully cooled. The cold air after absorbing heat is discharged from the filter 15 on the box door 2. In this process, the pump body 10 operates, so that the water in the cold water pipe 7 that has absorbed heat is cooled. It enters the discharge pipe 9, and then enters the cooling box 11 for cooling, and flows back to the cold water pipe 7 through the input pipe 8, and is used to dissipate the heat dissipation fins 6 that are fitted with the pipe body, thereby dissipating the heat dissipation of the device connected to the heat sink 5, and cools the device inside the box 1 at the same time as the fan 13, and the cooling effect is ensured.
