What are the advantages of cooling by hydrogen generators?
The two main advantages of cooling by hydrogen generators are its density is 1/14th of the air and its thermal conductivity is 6.7 times that of the air. These two properties of the hydrogen gas have the following advantages: · The noise generated by the alternator is reduced considerably due to the lighter cooling medium and lower friction. · Windage losses which are proportional to the density of the cooling medium are drastically reduced. · The reliability of the insulation increases and its life span is prolonged. · The cooling surface required for Hydrogen cooling is considerably smaller than that needed for the air coolers due to high heat transfer rates · There is no possibility of the fire hazard in the machine if the failur...
