Cooling air duct of air cooling double cylinder diesel generator

Abstract

The invention discloses a cooling wind channel of a wind cooling double-cylinder diesel generator set, comprising a wind collecting header pipe, a pair of left and right cylinder upper windward covers, and a pair of left and right generator wind covers; wherein, the wind collecting header pipe is arranged at a wind outlet of the front end of the cooling channel and faces the side board of the outer shell of the generator set, the upper windward covers are sheathed and fixed at the cooling plate position at the upper part of the left and right cylinders, and are communicated and tightly connected with the wind inlet at the rear end of the wind collecting header pipe, the generator wind covers hold each other at the periphery of the generator temperature lowering fan cover shell, the bottoms thereof are connected with the seat of the generator set and the tops thereof are respectively communicated and tightly connected with the wind collecting header pipe; the above is the main characteristics of the invention which also has the advantages of reasonable structure, convenient mounting and dismounting, and good effects of temperature lowering and noise eliminating.

Description

technical field [0001] The invention relates to a cooling air channel of an air-cooled double-cylinder diesel generator set, belonging to the technical field of fuel engine manufacturing. Background technique [0002] The noise reduction and temperature reduction of diesel generator sets is one of the important research topics in the industry. [0003] The cooling of the existing generator sets (including single cylinder and double cylinder) is the axial flow cooling air produced by the cooling fan of the diesel engine, which passes through the cylinder (mainly the heat sink position), and then passes through a wind collecting hood from the air collecting The air duct is discharged to the outside of the machine. The cooling of the generator is discharged to the outside of the machine through the wind collecting cover and the collecting pipe by the air outlet located at the top of the generator cooling fan cover. [0004] The above-mentioned cooling air ducts in the prior ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned cooling air duct in the prior art will inevitably cause the cooling air generated by the cooling fan of the diesel engine and the generator to flow out of order, and stay in the power generation In the casing of the unit, this not only makes the cooling effect poor, but also the diffuse cooling air will collide with the casing and resonate to generate secondary noise
