(Summary description) Solar photovoltaic power generation may become one of the active energy sources of world energy consumption in the future. It may not only replace part of conventional energy and become the main body of world energy. It is expected to account for 30% of the total energy by 2025, and the proportion of solar photovoltaic power generation in the world's total power supply is expected to reach more than 10%.

Solar photovoltaic power generation may become one of the active energy sources of world energy consumption in the future. It may not only replace part of conventional energy and become the main body of world energy. It is expected to account for 30% of the total energy by 2025, and the proportion of solar photovoltaic power generation in the world's total power supply is expected to reach more than 10%.
Photovoltaic inverter is one of the core equipment of photovoltaic grid connected power generation system. It plays a key role in realizing the conversion of solar energy and electric energy. Photovoltaic cell modules convert solar energy into DC energy, which is transformed into AC energy synchronized with AC power grid through inverter, and sent to power grid to realize grid connected power generation.
However, because the stability of many key electronic components is greatly affected by the ambient temperature, it is very important to design a good heat dissipation solution to ensure the normal operation and stable performance of the photovoltaic inverter power system. High power inverters and frequency converters are pursuing high efficiency and small size. Due to the large amount of heat generated by the operation of high-power chips, transformers, MOSFETs and other devices, the temperature of the whole photovoltaic inverter power supply system rises. In order to maintain a stable working temperature, it is necessary to solve the problem of heat dissipation. So how to solve the heat dissipation problem of photovoltaic inverter? At present, the power supply is generally equipped with aluminum heat sink, which is not enough for passive heat dissipation. For example, adding a fan on the heat sink to strengthen wind circulation and implement forced air cooling can take away a large amount of heat in the shortest time, ensure that the power supply system works at a relatively constant and ideal ambient temperature and ensure the stability of the inverter power supply, The service life of the inverter power supply is greatly improved.
