Air-cooled inverter generator Technical Field The utility model relates to the field of power electronic equipment, in particular to an air-cooled inverter generator. Background Along with the continuous development of power electronics technology, an inverter is used as a key device for converting direct current into alternating current, and plays an important role in the fields of industrial automation, renewable energy power generation, power grid regulation and the like. In particular, in generator systems, inverters are widely used to convert ac power generated by a generator to dc power or other forms of electrical power to meet different load demands. However, the inverter can generate a large amount of heat in the operation process, and if the heat cannot be timely and effectively dissipated, the temperature inside the inverter is too high, so that the working efficiency and the service life of the inverter are affected, and even potential safety hazards are caused. In the prior art, the heat dissipation mode of the inverter is mainly lateral air suction heat dissipation. The side-mounted air suction and heat dissipation is realized by arranging an air suction port on the side surface of the inverter and utilizing natural air cooling of the external environment or air suction of an auxiliary fan. The following problems exist in the practical application of the heat dissipation mode: 1) The heat dissipation effect is limited, namely, the natural wind speed is lower, hot air is not easy to exhaust, and the heat dissipation efficiency is low; 2) The adaptability of the high-temperature environment is poor, the temperature of the external air is higher in the high-temperature environment, the heat dissipation effect is further reduced, and the inverter is easy to overheat; 3) The side suction inlet occupies the side space of the inverter, which may conflict with the layout of other components such as the starter assembly or the oil tank, and the compactness of the whole structure is affected; 4) The side air suction inlet is lower, is easily influenced by external environment, such as rainwater, dust and the like, and can cause the inside of the inverter to be affected by damp and dust accumulation, thereby influencing the reliability and the safety of equipment. In summary, the prior art still has many disadvantages in the heat dissipation manner of the inverter, especially in a high-temperature environment, the problems of insufficient heat dissipation effect, reduced inverter efficiency, hidden safety hazards, and the like seriously affect the reliability and performance of the device. Therefore, the person skilled in the art is dedicated to develop an air-cooled inverter generator which can effectively improve the heat dissipation effect of the inverter and adapt to high-temperature environment.
