[0002] An air-cooled inverter is a special power conversion device that mainly uses air-cooling technology to handle the heat generated during the inverter process, ensuring the stable operation of the inverter.

[0003] In existing technologies, based on the combination of inverter technology and air-cooling technology, when DC power is input to the inverter power supply device, the inverter converts DC power into the required AC power output by controlling the on and off time of the switching devices; at the same time, the air-cooling system starts up, and the heat generated inside the inverter is carried away by air flow devices such as fans, ensuring that the inverter power supply device operates within the normal operating temperature range.

[0004] However, in the aforementioned prior art, electronic circuit boards and electronic components cannot be isolated from the external environment, cannot be dustproofed, and have poor heat dissipation. Utility Model Content
