The invention discloses an inverter cooling structure for a variable frequency generator set. A base (1) is in a polygon closed structure which is surrounded by a plurality of radiating panels (2), wherein one or more radiating panels of the base are provided with circuit boards (5); radiating fins (4) are arranged on the inner wall of an airflow passage (3) in the base (1); an air inlet (5) is formed in one side of the airflow passage (3); an air inlet hole (7) is formed in an air inlet bracket (6) arranged at the air inlet (5) of the airflow passage (3); an air outlet (8) is formed in the other side of the airflow passage (3); an air outlet hole (10) is formed in an air outlet bracket (9) at the air outlet (8) of the airflow passage (3); and a seal ring (13) is arranged between an exhaust inlet (12) of a fan (11) of the variable frequency generator set (14) and the air outlet bracket (9).
Description
technical field [0001] The invention relates to an inverter cooling structure of a variable frequency generating set. Background technique [0002] The relatively mature frequency conversion generator sets are all 1~3kw low power, and the higher power frequency conversion generator sets are relatively rare in the market, and the influencing factor is that it is limited by the conversion capacity of the inverter. However, the inverter of the current high-power variable frequency generator set has no cooling structure, and it is easy to burn out after long-term use, thereby causing the paralysis of the entire variable frequency generator set. Contents of the invention [0003] The invention provides an inverter cooling structure of a variable frequency generator set, which combines the heat exchange airflows that need to be cooled by multiple inverters into the airflow channel, so that the volume is greatly reduced, and it is convenient for the inverter generator set with a ...
