Description
Technical Field
[0001] The present application relates to the technical field of generator sets, and particularly to an inverter generator set. Background Art
[0002] In the power system, the generator set is one of the core devices, and its operating state directly affects the stability of the power system. Among them, the inverter module is an important part of the generator set, and its working efficiency and stability have an important impact on the performance of the generator set. However, a large amount of heat is generated during the operation of the inverter module. If this heat cannot be dissipated in time, it will seriously affect the normal operation of the inverter module and may even cause its damage. Therefore, how to effectively cool the inverter module and ensure its normal operation is a problem that must be solved in the design of the generator set.
[0003] In the prior art, the inverter module is usually arranged above the engine, and then holes are opened in the engine air guide cover, and at the same time, a large number of cumbersome air ducts are made to cool the inverter module. However, this cooling method has the following problems: First, opening holes in the engine air guide cover can only dissipate heat from a small part of the inverter module and cannot completely cover the heat dissipation surface of the entire inverter module; second, it is necessary to make a cumbersome air duct structure, resulting in an increase in cost; finally, arranging the inverter module above the engine will greatly increase the height of the generator set, resulting in an increase in the overall volume of the generator set and an increase in packaging and transportation costs.
[0004] Therefore, the prior art has defects and needs to be improved and developed. Utility Model Content
