Partitioned container for high output mobile generator

A mobile generator unit comprising:

• a generally closed container having a peripheral wall defining an inner chamber;
• a first and second transverse partition wall inside said container inner chamber separating said inner chamber into a first and a second compartments and an intermediate compartment between said first and second compartments;
• a power generating motor carried by said container in said first compartment;
• a radiator assembly carried by said container in said second compartment and operatively linked to said motor for cooling said motor;
• a first fresh air intake port provided in said trailer peripheral wall in said first compartment, for cooling said motor;
• a second fresh air intake port provided in said trailer peripheral wall in said second compartment, for cooling said radiator assembly;
• a hot air outlet port provided in said trailer peripheral wall in said intermediate compartment for exhausting warm air from said inner chamber;
• a first air channel linking said first and intermediate compartments;
• a second air channel linking said second and intermediate compartments;
• and
• a plenum air fan assembly provided in said intermediate compartment, operatively connected to said motor and rotating about a rotational axis radially offset relative to said hot air outlet port, said plenum air fan assembly comprising a first and a second coaxially extending fan portions separated and integrally linked to fan plate diametrally extending in said plenum air fan assembly between said first and second fan portions, said first fan portion being positioned in facing operative register with said first air channel for sucking air out of said first compartment and expelling this air out through said hot air outlet port, and said second fan portion being positioned in facing operative register with said second air channel for sucking air out of said second compartment and expelling this air out through said hot air outlet port, with said second fan portion being axially longer than said first fan portion for providing a greater air flow in said second compartment than in said first compartment.

• a first fresh air intake opening provided in said trailer peripheral wall in said first compartment, for cooling said motor;
• a second fresh air intake opening provided in said trailer peripheral wall in said second compartment, for cooling said radiator assembly, with said first fresh air intake opening being smaller than said second fresh air intake opening;
• a hot air outlet port provided in said trailer peripheral wall in said intermediate compartment for exhausting warm air from said inner chamber;
• a first air channel linking said first and intermediate compartments;
• a second air channel linking said second and intermediate compartments;
• and
• an air fan assembly provided in said intermediate compartment and operatively connected to said motor, said air fan assembly having a first fan portion connected to said first air channel for sucking air out of said first compartment and expelling this air out through said hot air outlet port, and a second fan portion connected to said second air channel for sucking air out of said second compartment and expelling this air out through said hot air outlet port, with said second fan portion having a greater air flow debit rate that said first fan portion.
