Portable engine-generator set

摘要

A portable engine-generator set is provide, which includes a soundproof cover defining an internal space for housing the components of the engine-generator set. The internal space comprises an intake compartment, a heat source compartment and an exhaust compartment. The heat source compartment comprises first and second sub-compartments which form independent cooling wind passages, each of the sub-compartments having an intake port in communication with the intake compartment. The exhaust compartment has an exhaust port in communication with the atmosphere, and intake ports in communication with the first and second sub-compartments such that air flow from the first and second sub-compartments are combined in the exhaust compartment. The engine and muffler of the engine are positioned in the second sub-compartment and the exhaust gas from the muffler flows into the exhaust compartment and is combined with the flow from the first and second sub-compartments, thereby rapidly cooling the exhaust gas and reducing the noise therefrom. The exhaust compartment includes sound absorbing material on the walls thereof to form a silencer box.
