Description

TECHNICAL FIELD

[0002] In today's energy field, energy storage converter, as one of the key equipment, plays a vital role. With the growing demand for energy storage and large-scale access of renewable energy to the grid, the performance and reliability of energy storage converter are increasingly concerned.

[0003] In the working process of energy storage converter, a large amount of heat will be generated due to the continuous conversion and control of internal electronic components. If this heat cannot be dissipated in time and effectively, it will have many adverse effects on the performance of energy storage converter. First of all, high temperature will lead to the performance degradation of electronic components, such as increased resistance, reduced capacitance, etc., thereby affecting the conversion efficiency and stability of energy storage converter. Secondly, the life of electronic components will be greatly shortened in a long-term high-temperature environment, increasing the maintenance cost and replacement frequency of the equipment. In addition, high temperature may also cause safety hazards, such as overheating, which may cause fire and explosion of components.

[0004] At present, the existing energy storage converter cooling methods mainly include natural cooling, air cooling and liquid cooling. Natural cooling relies on the heat conduction of the equipment itself and the heat exchange with the surrounding air to dissipate heat. This method has limited cooling effect and is difficult to meet the cooling needs of high-power energy storage converters. Air cooling blows external cold air into the equipment interior through a fan to take away heat, but this method is easily affected by environmental factors such as dust and humidity. At the same time, the cooling effect of the separate fan is poor. Although liquid cooling has good cooling effect, the system structure is complex, the cost is high, and there is a risk of cooling liquid leakage.

Therefore, there is an urgent need for a new type of energy storage converter that is easy to cool to meet the growing demand for energy storage and conversion. UTILITY MODEL CONTENT

[0032] Working principle

[0033] The closed cavity 8 can prevent the gas and impurities in the external environment from entering the closed cavity 8, thereby improving the working efficiency and effect of the energy storage converter electrical element 9. The circulating fan 10 blows air to the elements in the cavity of the closed cavity 8, thereby forming circulating air in the closed cavity 8, and the flow field passes through each element more fully. The air flows through each heating element in turn, thereby cooling each heating element to achieve the purpose of cooling. After the air exchanges heat with the elements, the air becomes high-temperature air, and the heat loss is transferred from the elements to the air. The high-temperature air is cooled by the heat exchanger 11 to become lower-temperature air. The high-temperature air in the closed cavity is transferred to the ventilation cavity 20 through the heat exchanger 11.

[0034] The radiator fan 13 and the heat exchanger ventilation cavity fan 19 suck in the external cold air from the air inlet plate 3 of the ventilation cavity 20 into the ventilation cavity 20. The entering cold air is divided into two air flows. One air flow directly flows through the radiator 15, and the IGBT assembly of the energy storage converter electrical element 9 in the closed cavity 8 directly exchanges heat through the radiator 15. The other air flow enters the heat exchanger 11 through the heat exchanger air inlet duct 18, and carries out the heat in the closed cavity 8 after heat exchange. The heat flows out of the air outlet of the heat exchanger 11, and then combines with the air flow passing through the radiator 15, and then flows out of the product to the outside through the air outlet plate 6 of the energy storage converter.
