Diesel generator set for realizing heat dissipation and noise reduction by adopting labyrinth branch air ducts

Abstract

The invention discloses a diesel generator set for realizing heat dissipation and noise reduction by adopting labyrinth branch air ducts. The diesel generator set comprises a base, a heat isolation bin and a main machine bin, wherein the heat isolation bin and the main machine bin are arranged in a mute box body, and an air-cooled generator, a diesel engine and an air inlet resonance box are arranged in the main machine bin; a labyrinth inlet air distribution chamber is arranged on the base, and the upper part of the labyrinth inlet air distribution chamber communicates with the air inlet resonance box; a first cold air distribution port and a first branch air duct used for cooling radiant heat in the main machine bin are formed in one side of the labyrinth inlet air distribution chamber;a second cold air distribution port and a second branch air duct used for providing working air combustion and waste gas exhaust for the diesel engine are formed in the upper part of the air inlet resonance box; a third cold air distribution port and a third branch air duct used for cooling the diesel engine are formed in one side of the air inlet resonance box; and the first branch air duct and the third branch air duct are connected into the heat isolation bin, and the second branch air duct penetrates through the heat isolation bin. The air-cooled generator set is good in ventilation and heat dissipation and low in noise.

Description

technical field [0001] The invention relates to the technical field of diesel generator sets, in particular to a diesel generator set that adopts a labyrinth branch air duct to realize heat dissipation and noise reduction. Background technique [0002] In the existing air-cooled and sound-generating generator set, the cooling airflow inside the machine compartment comes from the power end and the end of the motor. [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, r...

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.
