Background technology
Problem when diesel generating set works is exactly the heat dissipation problem that generates heat, another is exactly asking for noise abatement noise reduction
Topic, often both of these problems are contradictory each other, solve to get up to compare to be difficult to a two indices and all reach perfect condition, this is
The problem of annoying generating set manufacturer always.
Currently, the diesel engine thermal efficiency can only have 40% or so, it is meant that remaining most of other than switching to this part of kinetic energy
It has been wholly converted into thermal energy to distribute or be discharged with tail gas, in addition there be 25% or so mechanical friction loss this 40% the inside, equally
There is heat that need to distribute.Generator is also the same, and efficiency can reach 75% or so, but still have 25% or so energy to switch to heat,
Mainly mechanical friction heat, electric current generate vortex heat by conductor temp.-elevating and magnetic field.Open type generating set can be directly sharp
It is contacted with outside atmosphere, radiating condition is preferable, and there is no the high problems of temperature, but it just subtracts noise without any substantially
It makes an uproar the measure of noise reduction.

Raw aerodynamic noise, in addition also combustion noise and mechanical friction noise radiated by machine surface.The noise master of generator
If rotor friction noise and electric motor fan noise.
For this purpose, for cooling this problem that radiates, current most of production firms use installs electronics in generator cavity
Fan, or using the type of cooling of water cooling, since unit inner space is limited, water-cooling structure arrangement is complex, and lets out
There are security risks for leakage, and electronic fan cooling effect is limited, and reliable long-term working is bad, itself will also generate heat,
Electronic circuit, which goes wrong, to be stopped.
The condition significantly of the three of heat dissipation, first, heat dissipation area, second is that the temperature difference, third, air flows, and most important problem is just
It is air flowing to be generated.And for this problem of noise reduction, it has been deep-cut to pole in reduction engine, generator noise source this part
It causes, is now only solved by sound insulation and sound-absorbing.
