The resonance box is provided with a labyrinth air inlet shunt chamber on the base, the upper part of the labyrinth air inlet shunt chamber is connected to the air inlet resonant box, and one side of the labyrinth air inlet shunt chamber is provided with a first cold air shunt port and is formed for the main engine compartment. The first branch air duct for cooling by radiant heat, the upper part of the intake resonant box is provided with a second cold air split port and forms a second branch air duct for providing diesel engine working air combustion and exhaust gas exhaust, the intake resonant box One side is provided with a third cold air distribution port and forms a third branch air duct for cooling the diesel engine, the first branch air duct and the third branch air duct are connected to the thermal compartment, and the second branch air duct passes through the heat compartment. The air-cooled generator set of the invention has good ventilation and heat dissipation and low noise.

Description

technical field [0001] The invention relates to the technical field of diesel generator sets, in particular to a diesel generator set which adopts labyrinth branch air ducts to realize heat dissipation and noise reduction. Background technique [0002] In the existing air-cooled sound generator set, the cooling airflow inside the engine room comes from the power end and the motor end. After the airflow converges in the middle, it flows into the muffler compartment and then is discharged out of the engine compartment. [0003] The problems existing in the air-cooled sound generator set in the prior art are: the radiant heat of the engine room accumulates in the warehouse, which leads to an increase in the temperature of the warehouse, shortens the life of electronic components, batteries and rubber parts, etc., and increases the failure rate; The model uses a small electric fan to extract a part, but there are still problems of uneven hot air flow and uneven heat dissipation;...

AI Technical Summary

Problems solved by technology

[0003] The problems existing in the air-cooled sound generator set in the prior art are: the radiant heat of the machine cabin gathers in the cabin, causing the temperature of the cabin to rise, shortening the life of electronic components, batteries and rubber parts, etc., and increasing the failure rate; causing some The model uses a small electric fan to extract a part, but there are still problems of uneven hot air flow and uneven heat dissipation; the suction port of the generator is located below the bottom of the unit, close to the high temperature area, resulting in a high temperature rise of the generator winding

In addition, the noise radiation of diesel generator sets is also relatively high.
