a generator set

Abstract

The invention discloses a power generator unit. A machine case divided into a heat dissipating bin and a power bin, a first fan, a first air inlet and an air guiding cover are included, wherein an engine, a power generator and a silencer are arranged in the power bin; the air guiding cover is arranged in the periphery of the silencer and the top is provided with an opening, and the air guiding cover is matched with the top wall of the power bin, so that cooling air flow is guided to cool the portion, encircled by the air guiding cover, in the periphery of the silencer; the end, close to the heat dissipating bin, of the air guiding cover is provided with a second air inlet, and the other end of the air guiding cover is provided with a second air outlet; cooling air flow generated by the first fan flows through the engine and the power generator, and then the cooling air flow flows into the air guiding cover through the second air inlet; and after the corresponding periphery of the silencer is cooled, the cooling air flow is discharged upwards from the second air outlet to the outside through a first air outlet in the top wall of the power bin. Under guiding of the air guiding cover,the cooling air flow takes away the heat corresponding to the periphery of the encircled silencer, and directional and concentrated heat dissipating on the silencer is achieved, so that the overall heat dissipating effect of the power bin is better.

Description

technical field [0001] The invention relates to the technical field of power generation, and more specifically, to a generator set. Background technique [0002] A generator set driven by an engine, especially a high-power generator set, will generate a lot of noise during operation. For curbing its noise, prior art product is made silent generating set mostly by adding cabinet and laying means such as sound-absorbing material. In this way, the main components of the generator set including the engine, the generator, the radiator attached to the engine, the muffler, etc. are all placed in the casing, and a large amount of heat is bound to be generated and accumulated in the casing and generate relatively loud noises. For this type of generator set in the prior art, for better heat dissipation, the chassis is divided into a heat dissipation compartment, a power compartment and a muffler compartment, and the heat dissipation design is carried out according to the compartments...

AI Technical Summary

Problems solved by technology

This kind of power bin, because of its large internal space, the flow of cooling air in the bin is scattered and turbulent, and the heat dissipation effect in the bin is not good; especially when the muffler is built in the power bin, the heat retained in the bin is even greater. more, exacerbating the poor heat dissipation in the warehouse; at the same time, the noise of the cooling air inlet of this power warehouse is also relatively high

Therefore, the problems existing in the power bin of the prior art are: poor cooling effect and high noise
