Description

Technical Field

[0001] The invention belongs to the technical field of heat dissipation structures of diesel generator power systems, and in particular relates to a cabin structure of a diesel generator based on the principle of double-field coupling enhanced heat dissipation. Background Art

[0002] The market has higher and higher requirements for the power of diesel generator sets. As the power of diesel generator sets increases, the heat dissipation requirements are gradually increasing. However, the existing diesel generator set cabin air inlet setting makes it impossible for the air intake to completely take away the heat generated by the heating components in the cabin, which leads to heat accumulation in the cabin. At the same time, since the engine compartment and the heat dissipation compartment are integrated, the intercooler radiator and the engine radiator are directly installed in the engine compartment, which causes the cooling air entering the intercooler radiator to be heated by the heat accumulated in the cabin first, so that the intake temperature of the cooling air entering the intercooler radiator is much higher than the ambient temperature. At the same time, the cooling air passes through the intercooler radiator and then enters the engine radiator, which further increases the intake temperature of the cooling air entering the engine radiator. If the intake temperature of the cooling air of the two radiators is too high, the heat dissipation capacity will be reduced. In severe cases, there will even be an alarm phenomenon of excessive engine water temperature, which is more prominent in high temperature environments.

[0003] Therefore, designing a diesel generator cabin structure based on the principle of dual-field coupling enhanced heat dissipation to reduce the inlet air temperature of the intercooler radiator and the engine radiator, thereby effectively improving the heat dissipation efficiency of the two radiators, has become a technical problem that needs to be urgently solved by technicians in the relevant technical field.
