Description

Diesel generator set with good heat dissipation performance

technical field

The utility model belongs to the manufacturing field of diesel generating sets, in particular to a diesel generating set with good heat dissipation performance.

Background technique

Diesel generator set is a kind of power generation equipment with diesel as the main fuel. The diesel engine is used as the driving force to drive the generator (ie electric ball) to generate electricity and convert kinetic energy into electrical energy and thermal energy. The whole set of diesel generating set is mainly divided into three parts: diesel engine, generator and controller.

At present, most of the solutions to the heat dissipation of diesel generator sets are provided with air inlets and air outlets on the silent cover of the unit. Most of the noise problems are solved by adding traditional noise reduction and sound absorption structures to the unit. Although this traditional structure can play a certain role in reducing the noise of the unit, this structure sacrifices the internal ventilation of the unit in exchange for reducing the emission noise. This affects the heat dissipation performance of the diesel generator set, which in turn leads to a large power loss of the unit.

How to design a diesel generator set structure that can meet environmental noise emission standards and have good heat dissipation performance has become an important topic in the current industry.
