[0002] Marine generator sets generally include standard marine diesel generator sets and emergency marine diesel generator sets. A generator set usually consists of more than one generator, and each generator needs to be controlled by a frequency converter to control the generator's power output.

[0003] For example, in the prior art, there is a marine generator set frequency converter regulating device with publication number CN 222089468 U. A partition is fixedly installed in the middle of the housing, dividing the inner cavity of the housing into a frequency converter placement cavity and a generator set placement cavity. The generator set is installed in the generator set placement cavity, and multiple sets of frequency converters are fixedly installed in the frequency converter placement cavity, arranged evenly vertically. The spacing between each set of frequency converters is equal, and a guide plate is provided between two adjacent sets of frequency converters. A cold air exhaust module is installed on one side of the frequency converter placement cavity, and a hot air absorption module is installed on the other side. This marine generator set frequency converter regulating device can effectively cool the frequency converters and prevent them from overheating and burning out.

[0004] However, when the device is in use, it only blows cold air from one side of one of the inverter bodies to the other. And because the inverters are the same size, the inverter at the front end can easily block the cooling of the inverter at the back end, thus reducing the cooling effect of the inverter.

[0005] Therefore, it is necessary to provide a frequency converter for marine generator sets to solve the above-mentioned technical problems. Utility Model Content
