Description

Technical Field

[0001] The utility model relates to the technical field of diesel generators, in particular to a novel air intake and exhaust device for a diesel generator set. Background Art

[0002] Normal ventilation and cooling of diesel generator sets is a necessary condition to ensure the rated power output of the units. The cooling of air-cooled units mainly relies on the radiation of heat from the engine cylinder to the air. If the ventilation is not handled well in a relatively closed small space, it is easy to cause high-temperature shutdown. In the prior art, when the diesel generator box is ventilated internally, the airflow is relatively concentrated, and the airflow distribution is not uniform. The heat inside the diesel generator box cannot be evenly taken away, which will cause local overheating and heat accumulation inside the diesel generator. Therefore, a new type of diesel generator set air intake and exhaust device is proposed to solve the above problems. Utility Model Content
